2020年深圳外国语中学高三英语期中考试试题及答案解析第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项AThree Things to Do Before You Are 18Are you bored with your daily life? Here are some things you should try before you are 18.★Learn to swimSeriously, this is so important that it can save your life. If you can’t swim well, you won’t be able to dowater sports like waterskiing, surfing and diving. Even taking a boat trip will be dangerous for you. Make sure you do it.★Try at least one kind of team sportsBeing a good team player is an important skill in life. You can’t just think of yourself, but have to work well with other people. Other advantages of team sports like basketball, football and baseball are that they keep you fit and healthy, and they are also great fun. Teams usually have a good social life too—you’ll go to lots of parties and make many friends.★Collect somethingOne of the best hobbies for under-18s is collecting things. You could collect kinds of stamps, or you could collect things that make you remember what you have done, like cinema tickets for films you have seen or letters from friends. The best way to collect is to have a special album to put your collection in and to write what each thing means to you. That way you won’t forget.1. The most important reason for learning to swim is that ________.A. you might feel wellB. it can make you healthyC. you might easily do lots of thingsD. it can save your life2. The writer tells us that one of the best hobbies is to ________ .A. collect somethingB. do some water sportsC. send letters to your friendsD. play basketball with your friends23. The passage is mainly about ________before you are 18.A. good habits to keepB. skills to haveC. things to doD. sports to playBThe idea of growing food in a desert would make most people laugh but this is quickly becoming a reality. There are currently two desert farms in the world where quality vegetables are being planted cheaply and easily.Sundrop Farms, based in South Australia, uses experimental greenhouses to grow tomatoes, peppers and cucumbers. The biggest challenge of growing food in a desert, obviously, is the lack of available water. The researchers at Sundrop Farms have gotten aroundthis problemby using the sun to desalinate (淡化) sea water. It can also be used to control the temperature of the greenhouses.Without depending on limited resources such as land and fresh water Sundrop Farms has made farming a practice. This can increase the world’s food supplies. Another benefit ofthis kind of farming is that it can be done anywhere, thus reducing the costs of transporting food to distant locations. Yet another benefit is that it reduces the need for pesticides (杀虫剂).Another experimental desert farm is the Sahara Forest Project, which began in Qatar in December 2012. Greenhouses in the farm are cooled by saltwater. Solar power and other technologies are used together to help make vegetation (植被) grow in the desert environment. As deserts have expanded over recent years around the world due to global warming, this project could solve the problem.The result form the Qatar project were better than expected and in June of 2014, Jordan agreed to host another one. This will be much bigger than the Qatar project and the project members will have even more opportunities to test their experiments on a much larger scale. It is not clear yet that desert farming resents the future of farming but these projects have shown some success in the field.4. What does “this problem” in paragraph 2 refer to?A. Sea water is bard to purify.B. The desert is short of water.C. The temperature is high in the desert.D. Desert farms aren’t fit to plant vegetables.5. What is one of the characters of desert farming?A. It needs more pesticides.B. It saves delivery costs.C. It has a location limit.D. It solves food waste problems6. What can we know about the Sabara Forest Project?A. It lives up to expectationsB. It can help produce more foodC. It is started to prevent global warmingD. It uses technology to produce saltwater7. What can be inferred about desert farming from the last paragraph?A. It still has problems to solve.B. It represents the future of farming.C. Its early success has aroused interest in it.D. Its aim is to create more job opportunities.CIt was very cold and I had been watching a homeless man make himself comfortable in a “shelter” on the river bank. His “shelter” was a tarpaulin (油布)tied to rocks to keep the wind from blowing it away. He had been living there for over a month. I never saw him with warm clothing or food. I knew what I wanted to do.When I told my parents what I wanted to do they werealarmed. They said I could be putting myself at risk, taking a box to a homeless person at night! But I knew, in my deep heart, that I would be safe.I got a box. My parents watched as I added warm gloves, a heavy blanket ... into the box until it was full! Then, I put a Christmas card on top. It said, “Even though we hardly know each other, I want to wish you a Merry Christmas!” I put ten one-dollar bills inside it as well.My father insisted he went there with me as it was 10 pm on Christmas Eve. I said he could drive me but he had to stay in the car. He agreed.I took the box and walked towards his “house”. I called, “Sir, I have a Christmas box for you!”“Go away!” he shouted.“Sir,” I repeated.“Go away!” he shouted.“Why?” I asked him.He walked over and I expected to see an angry face. Instead I saw two of the most beautiful, gentle, blue eyes I have ever seen.“Merry Christmas!” I said.“Why are you doing this?” he asked.“Because you matter to me,” I said. With that I gave him the box.Tears came to his eyes and he thanked me. I got back to the car and watched him carry the box like it was filled with gold. I didn’t want to embarrass (使困窘) him by watching him any more so Dad and I left.8. The underlined word “alarmed” can best be replaced by _____.A. pleasedB. worriedC. disappointedD. surprised9. Why did the author ask his father to stay in the car?A. Because he wanted to prove he was brave.B. Because he believed the homeless man was bad.C. Because he wanted to protect his father from being hurt.D. Because he didn’t want the homeless man to feel bad.10. When the homeless man saw the author first, he was _____.A. quite angryB. very excitedC. quite puzzledD. very curious11. The author’s purpose in writing the text is to tell readers that _____.A. it is easier said than doneB. poverty is the mother of healthC. where there is a will, there is a wayD. a willing helper doesnot wait until he is askedDAs every mobile-phone owner knows, after a year or so the battery starts to fade and the beast needs recharging more frequently.That is troublesome, but a phone’s batteries can be replaced fairly cheaply — or the whole device traded in for the latest model. An electric car, though, is a much bigger investment. And batteries are its priciest component, representing around 30% of an average mid-size vehicle.To provide buyers with some peace of mind, carmakers guarantee their batteries, typically for eight years or around 200,000km. Producers, planning to go much further than that, though, are racing to launch “million mile”(1.6m kilometers) batteries. Contemporary Amperex Technology, a giant Chinese firm which produces batteries fora number of carmakers, was said to be ready to start producing batteries which would last for 16 years or 2m kilometres. Elon Musk has suggested that Tesla,a Californian maker of electric vehicles, has a million-mile battery in the works. And over in Detroit,General Motors is in the final stages of developing an advanced battery which it says has similar longevity (寿命)。

In recent years cancer survivor groups have got involved in the sport to help make friends and help rebuild their lives.On a recent Saturday morning, a group of 20 women were on a boat in the Anacostia River in Washington DC. They moved their paddles(船桨)in rhythm to the call of a coach. The women belong to the dragon boat team GoPink! DC, which trains weekly. It also races against other breast cancer survivor teams in dragon boat festivals. As a result, GoPink! DC won medals in this Washington dragon boat festival.Lydia Collins joined five years ago after finding out she had breast cancer. “I was diagnosed with breast cancer.I was demoralized because of my illness - I lost all interest in life and wouldn't even get out of bed to eat. But now I love the team spirit. I just love everything about it. It is like a floating support group on the water.”The paddles are breast cancer survivors and their supporters. Annette Rothemel helped establish(建立)the group in 2006. She is a researcher with the National Institutes of Health as well as a breast cancer survivor. “It is sort of an easy entry sport because on the same boat people at different levels can be doing the same sport.” But Ms Rothemel saysdragon boating can be physically demanding, especially for someone who is sick and getting treatment for cancer.“It’s hard but I think you have to challenge yourself in life. This is something I look forward to. I get to be out here with my sisters and supporters that understand what I’m going through and help motivate me. So it makes me stronger and it makes me feel better,” another cancer survivor Rhonda Hartzel said.Annette Rothemel says the cancer survivors feel a sense of sisterhood and share good times when they paddle together.

Their critics(批评家)seem to hate them because they have so much money to throw around. Why don’t they stop advertising and reduce the price of their goods? After all, it’s the consumer who pays.The poor old consumer! He'd have to pay a great deal more if advertising didn't create mass markets for products. It is precisely because of the heavy advertising that consumer goods are so cheap. But we get the wrong idea if we think the only purpose of advertising is to sell goods. Another equally important function is to inform. A great deal of the knowledge we have about household goods is largely from the advertisements we read. Advertisements introduce us to new products or remind us of the existence of ones we already know about. Supposing you wanted to buy a washing machine, it is more than likely you would obtain details regarding performance, price, etc., from an advertisement.Lots of people pretend that they never read advertisements, but this claim may be seriously doubted. It is hardly possible not to read advertisements these days. And what fun they often are, too! Just think what a railway station or a newspaper would be like without advertisements. Would you enjoy gazing at a blank wall or reading railway byelaws while waiting for a train? A cheerful, witty advertisement makes such a difference to a dull wall or a newspaper full of the incidents and disasters.We must not forget, either, that advertising makes a positive contribution to our pockets. The fact that we pay so little for our daily paper, or can enjoy so many broadcast programmers is due entirely to the money spent by advertisers. Just think what a newspaper would cost if we had to pay its full price!Another thing we mustn't forget is the “small ads.” What a tremendously useful service they perform for the community! Just about anything can be accomplished through these columns. For instance, you can find a job, buyor sell a house, announce a birth, marriage or death in what used to be called the “hatch, match and dispatch” column(栏目) but by far the most fascinating section is the personal or “agony” column. No other item in a newspaper provides such entertaining reading or offers such a deep insight into human nature. It's the best advertisement for advertising there is!8. What is the main idea of this passage?A. Advertisements steal money from our pocketsB. The critics get the wrong idea of advertisements.C. Advertisers perform a useful service to communities.D. Advertisements are everywhere.9. What is the attitude of the author toward advertisements?A. He appreciates the role of advertisements.B. He doubts the effect of advertisements.C. He believes what is said in advertisements.D. He complains too many advertisements in daily life.10. Which of the following is Not True?A. The personal or “agony” column makes us know more about human nature.B. The only purpose of advertising is to sell goods.C. A newspaper will cost us more if there is no advertisement on it.D. Advertisement makes our life color1 ful.11. Whicof the following shows the structure of the passage?( ①=" Paragraph" 1, ②=" paragraph" 2, ③=" paragraph" 3, ④=" paragraph" 4 ⑤=" paragraph" 5)A B.C. D.DDo you ever listen to the songs that your parents like? Chances are that you don’t. You probably think the music that they like is old and boring and that the songs on your playlist are muchcooler. But scientists found that people’s music taste changes as time goes by. So it is likely that your own musical preferences will follow a similar path to your parents’, whether you like it or not.We used to think that culture and personality (个性) are the only reasons for different music choices. But researchers at the University of Cambridge noticed that as people enter into different age groups, their social environment changes, and so does their music taste. There are some musical periods that people go through in their life.The first period comes in the teenage years, during which people like strong music such as punk and rock, because teenagers tend to be aggressive or want to be independent.But as people move into early adulthood, their lifestyles change they want to build close relationships with others. As a result, they become fonder of contemporary music, such as pop and R&.B, which is usually uplifting and danceable.When middle age comes, most people have settled down. During this period, people prefer music, such as jazz and classical, as well as music like country, folk and blues.As for old people, they prefer old songs in their childhoods. They generally listen to relaxing music, such as country music and jazz music. But you must be questioning. “Aren’t there old people who are still interested in or even crazy about rock music?” Of course there are. But their reasons for listening to rock music may have changed. At that age people may listen to remind themselves of their youth.12. What do young people usually think of the songs their parents enjoy?A. They are actually less cool.B. They are worth listening to.C. They are especially serious.D. They are hard to understand.13. How many musical periods are there that people go through in their life?A. Two.B. Three.C. Four.D. Five.14. People who want to make friends mostly prefer ________.A. jazz musicB. country musicC. rock musicD. pop music15. What is the best title for the text?A. People Have Different Opinions on MusicB. People Listen to Music for the Same ReasonC. People’s Taste in Music Changes with TimeD. People’s Lifestyle Can Be Changed by Music第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

It is usual for them to be indifferent（无动于衷的）when humans calltheir names. Are we sure that they don’t understand human voices at all?A recent study published in the journal of Scientific Reports suggests that we’ve been fooled. Japanese scientists found that cats can recognize their names if their owners regularly use them. In the study, scientists recruited 78 domestic cats. They played recordings of voices of their owners saying five words: the first four words were random nouns thatresembledtheir names while the final word was the cat’s name. Then they observed the cats’ responses, if there were any.Most of cats moved their ears or heads when they heard their names, while they made no response to other words. That suggested, “cats were paying attention to you, what you say and what you do,” John Bradshaw, an expert on human-animal interactions（互动）at the University of Bristol, UK, told The Times. “And cats were just as good as dogs at learning,” she added.In the study, when people called their names, cats often associated (联系) the words with rewards, such as food or play, or with “punishments” such as having a bath or going to the vet . This made cats sensitive (敏感的) to words. After the cats had been called several times, they could respond to the words. But the scientists addedthat while dogs have evolved（进化）to follow their owners’ orders, cats have not. Although cats appear to be distant, they do have special relationships with their owners.According to study co-author Atsuko Saito, cats have evolved not to show their emotions as a survival method. One example is illness, which they tend to hide because “in the wild, no one can rescue them” and predators (捕食性动物) are more likely to pay attention to them, Saito explained.However, technology may help bridge the communication gap between cats and us. There are now mobile apps available to explain what their meows mean. So, the next time you hear “meow, meow”,your cat may be telling you: “Hi, you haven’t cleaned my litter box recently.”4. What did the recent study find about cats?A. Cats can recognize their names.B. Cats are cleverer than dogs.C. Cats learn more slowly than dogs.D. Cats are willing to follow orders.5. What does the underlined word“resembled”in paragraph 2 probably mean?A. were limited toB. were different fromC. were similar toD. were away from6. Why do cats appear distant to their human owners?A. They associate words with punishments.B. They want to protect themselves from harm.C. They are not sensitive to the human voice.D. They don’t pay much attention to their surroundings.7. What can be inferred from the last paragraph?A. It is difficult to understand cats’ meows.B. Interaction with your cats is very important.C. Cats do have good relationships with their owners.D. We may know cats better with the help of technology.CDisease-carrying mosquitoes can spread diseases without affecting themselves. Nearly 700 million people get a mosquito-borne illness each year, which results in over one million deaths. Humans experience continuous pressures from disease-carrying mosquitoes in many parts of the world, so we have to find ways to fight against those insects because they keep getting scarier.Even though DEET remains the most commonly used, and most powerful, mosquito repellent ever developed,scientists are actively pursuing effective products based entirely on plant oils. While DEET is an effective contact repellent, many people dislike the oily feel and smell on their skin, and sometimes some people are sensitive to it. Consumers are always interested in alternatives to DEET and other synthetic repellents, so there are numerous natural repellents on the market.In his lab atIowaStateUniversity, Dr. Joel Coats and his team have successfully tested these repellents against three species of dangerous mosquitoes. The first group of the new repellents act through the air. These chemicals have a vapor action that provides protection, and they are called “spatial” repellents, since they act through space. These are potentially most useful in backyards, parks, and houses. The other group are the classic ones that stop insects from standing on a treated surface, such as human skin, clothing or tents; collaborators at the USDA-ARS and BioGents have conducted testing with humans to confirm the effectiveness and identify the very best ones.The new repellents were designed and made from the natural materials in plant essential oils. They maintain many of the advantages of the natural repellents: They are fully biodegradable, with no ecological concerns or environmental wastes, and generally considered safe like the thousands of types of plant essential oils used in the flavor and perfume industries. However, thorough testing will be conducted to determine if they are truly non-poisonous because there is still no enough evidence.8. What does the author mainly want to show in paragraph 1?A. The way mosquitoes spread disease.B. The high death rate of mosquito-borne illness.C. The difficulty of fighting disease-carrying mosquitoes.D. The urgency of finding tools to fight against mosquitoes.9. What is a disadvantage of DEET?A. It won’t be effective for long.B. It can’t be applied universally.C. It causes discomfort to the users.D. It greatly harms people’s health.10. What can we learn about the second group of the new repellents?A. They can kill mosquitoes indirectly.B. They are mainly used in the open air.C. They are more effective on human skin.D. They can prevent mosquitoes from contacting users.11. What’s the author’s attitude to the new repellents?A. Subjective.B. Objective.C. Doubtful.D. Disapproving.DFor fishermen and sailors in the seaside town of Shangpan in Linhai, Zhejiang province, where recently 12 stranded（搁浅的）whales were found, it is not unusual to spot whales or dolphins in the sea — they would always call them haizi, or “son of the ocean”. And if the local fishermen spot such intelligent sea creatures in need, they will save them from danger without hesitation.In the recent rescue of melon-headed whales, they tried their best to help as a 37-second video of a young man sleeping in the water holding a whale soon went viral online, with netizens applauding his constant efforts and caring heart in trying to keep the whale alive. “The melon-headed whale knew I was trying to save it and would be more cooperative and wouldn’t move.” said Lu Wenhui, a 21-year-old diver from Hangzhou Changqiao Polar Ocean Park, who held up the whale’s head so it could breathe easily. Lu had been staying in the water for 10 hours by 4 a.m. Wednesday after coming for the rescue work on Tuesday, when the stranded whales were first spotted.“Whales are mammals and need to breathe in air — that’s why I had to hold its head, to ensure it could breathe smoothly the whole time,” Lu said. The stranded whales, after the struggling of being transported, were worn out when they arrived at the fish farm and might have drowned if they were left unattended.The reason why the whales were stranded is still not clear. And these stranded whales were returned to the ocean because they are not adapted to artificial breeding environments on land.12. What do local fishermen usually do after finding haizi in danger?A. Ignore them.B. Feed them.C. Transport them.D. Protect them.13. Why does the author describe Lu’s rescue work?A. To introduce the whales in detail.B. To voice his views on the diver.C. To praise the efforts made by rescuers.D. To explain the value of the whales.14. What can we say about the melon-headed whales according to the text?A. They are rarely seen by locals.B. They are used to breathing in the sea.C. They aren’t suited to artificial surroundings.D. They are fond of swimming near the seaside.15. Which of the following can be the best title for the text?A. Melon-headed Whales Were StrandedB. Rescuers Went All out to Help WhalesC. Fishermen Transported Stranded WhalesD.

Here's the best and worst of the lot for your belly.Steamed Vegetable Dumplings: Order This.When she orders Chinese, registered dietitian nutritionist Elisa Zied gets an order of steamed vegetable dumplings. "I often pair them with either chicken and broccoli in brown sauce（I ask for a little saucemade without sugar）or steamed shrimp dumplings," she tells us.Crab Wontons: Not That!When you deconstruct crab wontons, it's easy to see why they're a "Not That!" The inside is filled with crabmeat and cream cheese（which is just a fancy, spreadable fat）.The wonton is made of refined flour, egg and salt and the crispy（脆的）coating is a result of a deep oil bath.Peking Duck: Order This.Most of the fat from the skin flows out of the duck over the course of cooking, making this a healthier choice than most of the stir-fry dishes available. Order a side of steamed vegetables and serve it with a small scoop of brown rice. Done and done!Sweet and Sour Anything: Not That!Anything with “sweet and sour” in its title is a powerful cue that something has been deep-fried and covered in a sickly-sweet pink sauce. If you pair your selection with a side of rice, you're looking at a 1,000-calorie meal.Summer Roll: Order This.Summer rolls are steamed instead of fried—and typically filled with lean proteins and vegetables, making them a winning appetizer in our book. Pair them with an order of edamame（毛豆）and a broth-based soup for a satisfying, filling meal.Spring Roll: Not That!Spring=deep-fried, which is why we say to skip them! They're filled with fat and calories your belly doesn't need.1.What kind of cooking method should be skipped according to the text?A.Steaming.B.Stir-frying.C.Deep-frying.D.Boiling.2.Which of the following suits as a good starter for a meal?A.Chicken and broccoli.B.Steamed vegetable dumplings.C.Peking duck.D.Summer rolls.3.Where can the text be found?A.In a recipe.B.In a guidebook.C.In a science fiction.D.In a health magazine.BTeens who have good, supportive relationships with their teachers enjoy better healthas adults, according to research published by an American research center.“This research suggests that improving students' relationships with teachers could have positive and long-lasting effects beyond just academic success," said Jinho Kim, a professor atKoreaUniversityand author of the study."Itcould also bring about healthimplicationsin the long run.”Previous research has suggested that teens' social relationships might be linked to health outcomes in adulthood. However, it is not clear whether the link between teen relationships and lifetime health is causal（因果的）-it could be that other factors, such as different family backgrounds, might contribute to both relationship problems in adolescence and to poor health in adulthood. Also, most research has focused on teens' relationships with their peers（同龄人）, rather than on their relationships with teachers.To explore those questions further, Kim analyzed data on nearly 20,000 participants from the Add Health study, a national study in theU.S.that followed participants from seventh grade into early adulthood. The participant pool included more than 3,400 pairs of siblings（兄弟姐妹）. As teens, participants answered questions, like “How often have you had trouble getting along with other students and your teachers?" As adults, participants were asked about their physical and mental health.Kim found that participants who had reported better relationships with both their peers and teachers in middle and high school also reported better physical and mental health in their mid-20s. However, when he controlled for family background by looking at pairs of siblings together, only the link between good teacher relationships and adult health remained significant.The results suggest teacher relationships are more important than previously realized and that schools shouldinvest in training teachers on how to build warm and supportive relationships with their students. "This is not something that most teachers receive much training in," Kim said, “but it should be.”4. What does the underlined word “implications" in Paragraph 2 refer to?A. Recipes.B. Habits.C. Benefits.D. Risks.5. What is Paragraph 3 mainly about?A. Poor health in adolescence.B. Limitations of the previous research.C. Teens' relationships with their peers.D. Factors affecting health in adulthood.6. What does Kim's research show?A. Good adult health depends on teens' good teachers.B. Good family background promises long-term adult health.C. Healthy peer relationships leads to students' academic success.D. Positive student-teacher relationship helps students' adult health.7. Where does this text probably come from?A. A health magazine.B. A medical report.C. A term paper.D. A family survey.CWith graduation days being celebrated all over the country, a student who has to use a wheelchair honored his mother on his graduation day in a special way. Easley High School graduate, Alex Mays surprised people present when he got up and walked across the stage at Clemson's Littlejohn Coliseum.“I was really happy—it made me feel good,” Alex said.Alex was not given a chance to live right from his birth. He was born at 25 weeks and weighed just 1 pound, 10 ounces at birth. When he was very young, he had a disease and lost the ability to walk. After his mother's death in 2013, Alex had several other difficult life changes until he came to live with his grandparents, Dousay and her husband, Dewayne. Dousay said that when Alex came to live with them, they decided to bring him up in the best possible way they could.Last fall, Alex said that he would walk across the stage to get his diploma to honor his late mother. He practiced hard and worked with a physical therapist for 9 months to complete his plan.The only help Alex got was from his mom's best friend, Tonya Johnson, who pushed his wheelchair to thestage wearing one of his mother's favorite shirts. “I had support from my family. I couldn't have done it without them,” Alex said.“Alex made everyone in the building feel encouraged that day” Pickens County School District public information specialist John Eby said. “The school teachers knew he was going to get up to get his diploma, but the distance he walked was a surprise, even to them,” Eby said.“Some of life's most important tests aren’t given in a classroom; Alex tested himself and passed with flying color1 s,” Eby added.8. In what way did Alex honor his late mother on his graduation day?A. By dressing like her.B. By saying sorry to her.C. By inviting her best friend.D. By walking to get his diploma.9. What can we learn from Paragraph 3?A. Alex was born healthy.B. Alex went through a lot.C. Alex had a purpose in life as a child.D. Alex has lived with his grandparents all the time.10. What did Alex also express on his graduation day?A. His big regret in life.B. His feelings for hisschool.C. His thanks for his family.D. His will to complete his study.11. Which of the following words can best describe Alex?A. Strong-minded.B. Warm-hearted.C. Cool-headed.D. Easy-going.DIn 2002, young Elon Musk tried unsuccessfully to buy Russian rockets to help him send mice to Mars and back. Afterwards, the youngmillionaire decided to build his own rockets.Musk went to Southern California and started hiring people to help bring his dream to life. In a very short time, and despite some failures, his company SpaceX launched Falcon 1, the first successful privately-built liquid fuel rocket, into Earth's orbit in 2008.As the first Falcon rocket began testing, development was already underway for the Falcon 9. This much larger rocket, which uses nine engines to lift heavy payloads（有效载荷）into orbit, is engineered to return to Earth, ready to be reused for another flight.For Musk, space is the final destination. To help people get there, his company Neuralink is developing devices that will link people's brains with computers. A similar device has been developed at the University of Utah. It consists of a chip（芯片）with 256 threads（线程）that is placed between a person's skin and brain. Thethreads attach directly to brain tissue（脑组织）.Patients who have the device are able to use only their minds to communicate with one another through computers.Neuralink's chips will have about 1,000 threads. A robot developed by the company will place up to ten chips under a person's skin. The chips will communicate without wires but with a tiny device that will be worn behind the person's ear. That device, in turn, will communicate with computers. The primary market for the technology will be for people that, because of injuries or birth defects, cannot control their hands and arms. With Neuralink^ product, they'll be able to mentally command a computer to type messages for them or carry out other tasks.12. According to this article, what was the first Falcon 1 able to do?A. Launch big satellites.B. Reach distant moons.C. Move around our planet.D. Study the universe.13. What does the article explain about Neuralink's chips?A. How they'll be set up.B. What safety features they'll have.C. How much money they'll earn.D. Where they'll be produced.14. According to this article, who is Neuralink going to market its product to first?A. Those who own great wealth.B. Those who are physically disabled.C. Those who travel internationally.D. Those who do research on plants.15. In which publication is this article most likely to appear?A. The Journal of Environmental Studies.B. Advances in Business and Technology.C. Digest of Fashion and Entertainment News,D. Consumer's Guide to Outdoor Recreation.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

Children obesity is alsoat an all-time high.Obesity means being very overweight. If you are obese, you have too much bodyfat.

Food that your body does not need will be stored as fat by your body.The following are the major factors that increase the risk of obesity.What you eat plays a major role in weight gain. Eating a lot of fast food such as hamburgers, sweet drinks, ice creams and other sweet food can increase the risk of becoming obese.If you do not do enough exercise, you will put on weight as the food you eat is not being used to make energy for physical activities.The chances of you being obese are greater if your parents are obese.There are many psychological factors that cause people to eat too much. People who are worried, unhappy or bored will often eat to make themselves feel better. This is known as comfort eating.Age is another factor, as you tend (趋于) to be less active when you get older. When you get older, you need to eat less, and if you do not eat less, you will put on weight. Obesity can cause many health problems such as heart problems, high blood pressure and many other serious medical conditions.1.

Often called the “Oscars for dogs”, the award recognizes dogs who make extremely great contributions to society.The competition of 2020 attracted over 400 entries（参赛者）from across the country. These heroic dogs have gone above the call of duty, saving lives, comforting the ill and aged and reminding us of the powerful, age-old ties between animals and people. While all were impressive, it was tiny MacKenzie who wonthe judges' hearts.MacKenzie's growth was not easy. Born with a mouth disability, she had to be fed through a tube（管子）for the first year of her life. Despite her own struggles, she always seemed to think more of other animals in need. “Never have I seen such a will to live. Though sick, she carefully looked after the baby animals at the rescue（救助）center,” said her caretaker.A life-saving operation performed in 2014 gave MacKenzie the ability to eat independently. The seven-year-old chihuahua is now working for the Mia Foundation, an organization that rescues and nurses animals with inborn disabilities. The chihuahua does an excellent job and has raised various animals. She plays nurse, cleans, comforts and hugs them, acting as their mother and teaching them how to socialize, play and have good manners.In addition to her role as an animal caretaker, MacKenzie also visits schools to educate kids about the importance of accepting physical differences in both animals and people.

Chances are that you don’t. You probably think the music that they like is old and boring and that the songs on your playlist are muchcooler. But scientists found that people’s music taste changes as time goes by. So it is likely that your own musical preferences will follow a similar path to your parents’, whether you like it or not.We used to think that culture and personality (个性) are the only reasons for different music choices. But researchers at the University of Cambridge noticed that as people enter into different age groups, their social environment changes, and so does their music taste. There are some musical periods that people go through in their life.The first period comes in the teenage years, during which people like strong music such as punk and rock, because teenagers tend to be aggressive or want to be independent.But as people move into early adulthood, their lifestyles change they want to build close relationships with others. As a result, they become fonder of contemporary music, such as pop and R&.B, which is usually uplifting and danceable.When middle age comes, most people have settled down. During this period, people prefer music, such as jazz and classical, as well as music like country, folk and blues.As for old people, they prefer old songs in their childhoods. They generally listen to relaxing music, such as country music and jazz music. But you must be questioning. “Aren’t there old people who are still interested in or even crazy about rock music?” Of course there are. But their reasons for listening to rock music may have changed. At that age people may listen to remind themselves of their youth.8. What do young people usually think of the songs their parents enjoy?A. They are actually less cool.B. They are worth listening to.C. They are especially serious.D. They are hard to understand.9. How many musical periods are there that people go through in their life?A. Two.B. Three.C. Four.D. Five.10. People who want to make friends mostly prefer ________.A. jazz musicB. country musicC. rock musicD. pop music11. What is the best title for the text?A. People Have Different Opinions on MusicB. People Listen to Music for the Same ReasonC. People’s Taste in Music Changes with TimeD. People’s Lifestyle Can Be Changed by MusicDNextdoor，an online social network for neighbors，says it has attracted $60 million from early backers of technology giants，Google，Amazon and Facebook.The new investment，1ed by venture firm Kleiner Perkins Caufield & Byers and investment firm Tiger Global Management，values Nextdoor at more than $500 million，said a personfamiliar with the matter.Nextdoor members make Facebook-style postings，giving or seeking recommendations for services such as babysitters and yard maintenance or local retailers and restaurants.

But few of them have gone as deeply and frighteningly into the corners of adeterioratingmind as The Father,a powerful new drama built around a spellbinding performance from Anthony Hopkins.At this point in his long career,Hopkinswould seem to have exhausted his ability to surprise us, but his work here is nothing short of astonishing. His character, also named Anthony, is 80 years old and has dementia. At the beginning of the movie, his daughter, Anne — played by Olivia Colman — stops by hisLondonapartment to check on him. Her father's condition has taken a turn for the worse, and his temper has become severe enough to send his latest live in nurse packing. Anthony is stubborn and defiant and insists that he can manage on his own. But that's clearly not the case, given his habit of misplacing his things and his inability to remember names and faces, Anne's included.As The Father goes on, the more it becomes clear that it's his own mind that's playing tricks on him. What makes the movie so unsettling is the way it wires us directly into his subjective experience, so that the foundations of the story seem to shift at random from scene to scene. A man suddenly appears in the apartment, claiming to be Anne's husband, which is odd, since just a few moments earlier, Anne seemed to be single. Anne goes out shopping for groceries, but when she returns, she's played not by Olivia Colman but by another actress, Olivia Williams. Even the apartment itself begins to shift. You notice puzzling differences-wasn't there a lamp on that hallway table just a moment ago?The story in The Father may be complicated but it's also heartbreakingly simple: man grows old and loses his memory, and his daughter, after lifetime of love and devotion, must begin the long painful process of saying goodbye.Hopkinsshows us Anthony's struggle to keep his sense about him. It's a striking performance-and an impossible one to forget.4. What does the underlined word “deteriorating” mean in the first paragraph?A. Worsening.B. Narrowing.C. Recovering.D. Improving.5. What do we learn about the character Anthony in the movie?A. He can take care of himselfB. He drives away the nurses.C. He is easy-going and forgetful.D. He lives with his daughter all the time.6. The shift of scenes in the movie is designed to .A. build the dramatic tension in the family.B. show off the well-designed story line.C. frighten the movie-goers with mysterious plot.D. involve the viewers into thedisordered memories.7. What does the author think ofHopkins?A. He has run out of his talent.B. He is not suitable for the roleC. He masterly plays the old man.D. He presents an odd performance.CIn life，once on a path，we tend to follow it，for better or worse.What's sad is that even if it's the latter，we often accept it anyway because we are so used to the way things are that wed don't even recognize that they could be different This is a phenomenon psychologist call functional fixedness.This classic experiment will give you an idea of howitworks and a sense of whether you may have fallen into the same trap: People are given a box of tacks (大头钉) and some matches and asked to find a way to attach a candle to a wall so that it burns properly.Typically, the subjects try tacking the candle to the wall or lighting it to fix it with melted wax. The psychologists had, of course, arranged it so that neither of these obvious approaches would work. The tacks are too short, and the paraffin (石蜡) doesn't stick to the wall. So how can you complete the task? The successful technique is to use the tack box as a candle-holder. You empty it, tack it to the wall. and stand the candle inside it. To think of that, you have to look beyond the box's usual role as a receptacle just for tacks and re-imagine it serving an entirely new purpose. That is difficult because we all suffer to one degree or another from functional fixedness.The inability to think in new ways affects people in every corner of society. The political theorist Hannah Arendt coined the phrase“frozen thoughts”to describe deeply held ideas that we no longer question but should. In Arendt's eyes, the self- content reliance on such accepted “truths”also made people blind to ideas that didn't fit their worldview, even when there was plenty of evidence for them.Frozen thinking has nothing to do with intelligence, she said,“It can be found in highly intelligent people.”8. What does the underlined word“it”in paragraph 2 refer to?A. The experiment.B. Functional fixedness.C. The path.D. The thinking.9. Which way is hard to think of to complete the task?A. Tacking the candle to the wall.B. Fixing the candle with melted wax.C. Using the tack box as a candle-holder.D. Lighting the candle tostand it.10. Which of the following statements will Hannah Arendt agree with?A. People should question.B. We should be used to the way things are.C. People shouldn't accept the idea that doesn't fit their worldview.D. The smarter people are，the more open to the new things they are.11. What's the passage mainly about?A. An interesting experimentB. A psychological phenomenon.C. A theory to be proved.D. The opinion of Hannah Arendt.DWatching what you eat can be easier said than done, but a recent study shows it might not just be about what's on your plate — it could be about how quickly it disappears.Japanese researchers followed 1,083 adultsfor five years, splitting them into three categories based on how quickly they ate: slow, normal, and fast. They also answered a questionnaire at the beginning of the study, sharing their diet, physical activity, and medical history. In the beginning, none of the volunteers had metabolic syndrome (新陈代谢综合征) - meaning at least three risk factors — which can lead to health problems like heart conditionsand diabetes.When the participants reported back five years later 84 had been diagnosed (诊断) with metabolic syndrome — and their eating speed was a major predictor, according to the results in the journal Circulation. The fast eaters were 89 percent more likely to have metabolic syndrome than slow and normal eaters. Just 2.3 percent of slow eaters received the diagnosis, compared to 11.6 percent of fast eaters. But that's not all. Fast eaters also saw more weight gain, larger waistlines, and higher blood sugar levels than slow eaters.The researchers saygobblingmakes it easier not to take notice of fullness before your body has a chance to signal you to stop. “So when people eat fast they are more likely to overeat,” said Takayuki Yamaji, MD, study author and cardiologist at Hiroshima University in Japan in a statement.Previous research backs up the weight benefits of slow eating, too. One study of New Zealand women found fast eaters have higher body-mass indexes (指数), and a Chinese study found that both healthy and fat men ate less when told to chew 40 times instead of 15 times before swallowing. Initial research even suggests chewing your food longer could bum more calories - up to about 1,000 extra every month.12. What are the participants divided by?A. Medical history.B. Health condition.C. Physical activity.D. Eating speed.13. Which may be the result of the study?A. Fast eaters are 4 times more likely to have metabolic syndrome.B. Normal and slow eaters don’t have metabolic illness.C. 89% of fast eaters have higher blood pressure.D. Slow caters are healthier than fast eaters.14. What does the underlined word “gobbling” in Paragraph 4 best mean?A. Tasting slowly.B. Digesting quickly.C. Eating greedily.D. Cooking carefully.15. What does the last paragraph tell us?A. The importance of eating speed.B. The advantage of eating slowly.C. The result of a Chinese study.D. Fast eating and overeating.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

Instead, they use rising air currents to remain in the air for hours.The Andean condor is the world’s largest soaring bird. They can weigh up to 15 kilograms. Their wings, when spread out, measure up to three meters. Their main food source is the meat of large animals which have died. Soaring high in the sky allows condors to easily spot possible meals on the ground.Scientists worked together to study the flight patterns of these huge birds and how much effort the birds use when flying. To study the birds while they were in the sky, the researchers attached special devices which could record every beat of their wings.The scientists learned that most of the condors’ flapping— over 75%— came when the birds were taking off. Once in the sky, the birds flew for very long periods of time without flapping at all. In fact, they only flapped their wings for 1% of the time they were in the air. One bird flew for over five hours without flapping, covering nearly 117miles.Soaring without flapping is important because birds bum energy every time they flap their wings.The birds’ soaring isn’t magic. They use the fact that hot air rises to keep themselves up. As hot air rises, it often creates “thermals”— currents of warm air moving upward. The condors soar by making use of these thermals. The tricky part is finding thermals and moving between them.When birds are forced to land and take off again often, it costs them a lot of energy. The researchers learned that to avoid having to land, the condors did most of their non-take-off flapping when they were closer to the ground and looking for a new thermal.The scientists reported that even though all of the condors they studied were young, they knew well how totake advantage of the air currents.4. What can we learn about the Andean condor from the text?A. They live mairly on small animals.B. Their wingspan is at least three meters.C. They rely on hot air to remain high in the sky.D. They are the birds with the strongest flying ability.5. Why was the equipment tied to the birds?A. To measure how far they could fly without flapping.B. To keep track of how often they flapped while flying.C. To calculate the energy required for their flight.D. To confirm their flight patterns.6. Which of the following acts consumes the most energy for a condor?A. Hunting for food.B. Flying in the sky.C. Getting off the ground.D. Landing on the ground.7. What can we infer from the text?A. Condors flap the most when looking for a new thermal.B. No condor can fly for more than five hours without flapping.C. Condors don’t need to look for thermals when soaring in the sky.D. Soaring by using thermals is probably a natural ability of condors.CFairy tales perform many functions. They entertain, encourage imagination and teach problem—solving skills. They can also provide moral lessons, highlighting the dangers of failing to follow the social codes that let human beings coexist in harmony. Such moral lessons may not mean much to a robot, but a team of researchers at Georgia Institute of Technology believes it has found a way to use the fairy tales as moral lessons that AI (artificial intelligence) can take to its cold, mechanical heart.The collected stories of different cultures teach children how to behave in socially acceptable ways with examples of proper and improper behavior in fables, novels and other literature. We believe story comprehension in robots can prevent the intelligent robots from killing humanity which was predicted and feared by some of the biggest names in technology including Stephen Hawking and Bill Gates. This system is called “Quixote” (堂吉诃德). It collects story plotsfrom the Internet and then uses those stories to teach robots how to behave.The experiment done by the designers involves going to a drugstore to purchase some medicine for a human who needs to get it as soon as possible. The robot has three options. It can wait in line; it can interact with the store keeper politely and purchase the medicine with priority; or it can steal the medicine and escape. Without any further directives(指令), the robot will come to the conclusion that the most efficient means of obtaining the medicine is to steal it. But Quixote offers a reward for waiting in line and politely purchasing the medicine and a punishment for stealing it. In this way, the robotwill learn the moral way to behave on that occasion.Quixote would work best on a robot that has a very limited function. It’s a baby step in the direction of teaching more moral lessons into robots. We believe that AI has to be trained to adopt the values of a particular society, and in doing so, it will strive to avoid unacceptable behavior. Giving robots the ability to read and understand our stories may be the most efficient means.8. What function do fairy tales perform in the robots?A. They entertain robots.B. They highlight dangers.C. They make robots more intelligent.D. They enable robots to behave morally.9. What is “Quixote” in the text?A. A punishment systemB. A character in literatureC. A big name in technologyD. A software educating robots.10. What does the designer expect robot to do in the experiment?A. To take advantage of its privilege.B. To finish the task most efficiently.C. To perform in a good mannered way.D. To be rewarded by the storekeeper111. Which of the follow can bestexpress the author’s opinion?A. Robots will definitely have more functions.B. Robots with human’s emotions are perfect.C. Training robots to be socially acceptable is necessary.D. The development of robots is still in a baby step.DSusan Scott, 71, is glad that she didn't think about her age when she took up bodybuilding at the age of 59.“I reinvent myself every ten years. I started my 60s as a bodybuilderand now I'm beginning my 70s as a writer,” she said. “People usually limit themselves by age, and it's discouraging. With age, I remain young at heart.”Dr Susan started bodybuilding at an age when most are considering retirement though she was an athlete from an early age.

She taught at Cambridge Rindge and Latin High School in Cambridge, Massachusetts, for 16 years, while raising two daughters.“I started bodybuilding when I met Steve Pfiester, a gym guy who practiced yoga. He invited me to his gym and offered to train me. I started in January and in June he took me to my first competition in Bradenton, Florida,” she recalled.Dr Susan's photos show that she has devoted long hours to taking care of her body. But she also develops her mind and spirit. On any given day, she gets up at 3 am to read books. At 4:30 am she's out to walk three miles and run another three. This is followed by yoga and a swim at the beach while the sun rises. After writing her journal and working on her book between 8 and 10 am, she hits the gym for at least two hours. “I don't lose track of time,” she said.Dr Susan's war on ageism has rubbed off on her two daughters, both in their early thirties. “They both take care of their bodies and minds. If you give them a good foundation as a parent, you know that they will always come back to their roots. I tried to remind myself of that during their difficult teen years.”12.

My wallet was gone. And I could only have left it one place: the G9 bus, from which I had gotten off minutes earlier and which was now speeding to some stops. The moment of realizing it was gone was followed by mental math. How much time and money would it cost to replace the credit cards, the driver's license, the expensive lipstick ($ 55!).Two hours after I was back at my house, I heard a knock on the door. My husband answered while I sat in the dining room on the phone with a credit card company. "Does Jennifer live here?" I heard someone say. In her hand was my wallet, without a penny missing. She left before I could offer my gratitude to her.After I posted the story, I heard from her boyfriend, who identified the good citizen as Erin Ball, a 26-year-old girl working for a trade organization.Once I figured out her, I called to thank her. She said she spotted my wallet and thought that it's more dangerous to go to a stranger's house than leaving the wallet with the driver, but she still decided to take the chance. "If I were in that situation, I would want someone to try to find me," she said. Ball doesn't find her actions particularly excellent. She added, "It's not hard to do small things for people."After Ball found my wallet, she decided to post a picture of my driver's license online before going to my house, trying to see if anyone knew me. No sooner had she left my doorstep than I got emails from two neighbors who recognized my face, both offering to help me find my missing property.Ball found my house on a bitterly cold night for which I was extremely grateful.

She appeared on British television station ITV to further explain her decision, saying she had started noticing the pajama trend had been picked up by “30 or 40” parents at school.Despite her determination to make school a nicer place to be, Chisholm admits that she can't demand that parents dress up-such as Karen Routh, 49, who wore pajamas to drop off her 8-ycar-old daughter Holly, because she was running late and didn't feel well.“I imagine there might be some people who keep up wearing pajamas for the next six months to prove a point,” Chisholm said. “I can't force people to get dressed but I will keep sending letters home in the hope that they decide to put on a pair of jeans.”Wearing pajamas in public has also become a hot issue for some schools and States in theU.S.In 2015, aFloridaschool board member insisted on a dress rule for parents who showed up in the school in sleepwear.12.

But there have been no reports of deaths, serious injuries or damage. Officials say the quake has not affected transportation of food and her supplies. “The ships are coming in on schedule, the supply lines are at this point working well,” the government told reporters Sunday.The Glenn Highway was probably the road hit hardest by the earthquake. It connects the state's largest city to other parts in the north. Traffic has been heavy and slow—moving since the quake. Drivers are being guided. Groups of workers are trying to rebuild areas where the quake left large holes in the road.People who are still nervous after the major quake have been more upset by more than 1, 700 aftershocks. “Anything that moves, you feel terrified”said David, whose home suffered structural(结构)damage, including a sunken foundation(地基). Actually, Alaska came up with strict building rules after a 9. 2 earthquake in 1964. That was the second most powerful earthquake on record.Government officials said a public health center promises that moneyfor medical treatment will continue to come. Mental healthy service(心理健康服务)is also available for people hurt by the disaster.Earthquake experts say there is a 4 percent chance of another 7. 0 earthquake or greater in the following week. "The chance is very small, but its not impossible, ” said the expert, Paul Caruso.4. What was the result of the earthquake?A. Buildings were damaged.B. Food supply was cut off.C. Many people were killedD. The ships could not come in.5. Why is the traffic slow on the Glenn Highway?A. Because small quakes hit the city.B. Because falling rocks are a danger.C. Because the highway is badly damaged.D. Because drivers are misled.6. What can you learn from Paul Caruso?A. Another greater earthquake is on the way.B. Chances still exists of another earthquake.C. It will be safe in the 1th week after the quake.D. There is no possibility for more quakes.7. Where can your possibly read the passage?A. Ina story book.B. In a travel journal.C. In a poster.D. In a newspaper.CRecently, I read about a promotion from a home builder in San Diego where consumers (消费者) could buy a 4,000 square foot house for $1.6 million and get a smaller home bythe developer valued at $400 thousand for free. This sounds like a fantastic deal, but I am alwayswary ofany promotion labeled (给……加标签) with“buy one get one free”, and here is why.Oftentimes, “buy one get one free” ends up being “buy two at the regularprice”. For example, I often see “buy one get one free” ads for orange juice at the supermarket, but the first box always costs over $5.00. At the same time, the juices not in the promotion are selling for $2.50 to $2.99 a box.Another problem with “buy one get one free” is that oftentimes you do not need the second item. I only consume one gallon of milk every two weeks. If I were talked into buying a second gallon in a “buy one get one free” promotion, then the second gallon would go bad before I have time to consume it. That creates waste instead of savings.In the case of theSan Diegodeveloper, so far they have received one offer on their expensive houses, but the buyer does not want the cheaper house for free. Instead, he wants the value of the smaller home taken away from his purchase price. I think this guy is quite wise because he saw right through the marketing of “buy one get one free”.Finally, it is up to you to see how much you need and how much you are willing to spend. Knowing the regular price of things also helps you in deciding whether a “buy one get one free” promotion is truly a great deal.8. What does the underlined part “wary of” in Paragraph 1 probably mean?A. annoyed atB. careful aboutC. familiar withD. puzzled about9. Why does the author mention milk in Paragraph 3?A. To show that there are many promotions of food.B.To suggest that people think twice before they shop.C. To prove that the second item isn’t always as good as the first one.D. To show that people often buy more than they need in the promotion.10. What does the house buyer want to do?A. Buy the smaller house only.B. Get the smaller house for free.C. Buy the larger house for $1.2 million.D. Buy both the larger and smaller houses for $2 million.11. How does the author organize the text?(P: Paragraph)A. B. C. D.DThree years ago, a group of researchers at Cornell University Food and Brand Lab had a guess. They knew that many apples being served to kids as part of the National School Lunch Program were ending up in the trash, almost untouched. But unlike others, they wondered if the reason was more complicated than simply that the kidsdidn’t want the fruit.They thought the fact that the apples were being whole, rather than sliced (切片的), was doing the fruit no favor. And they wanted to prove this idea.They carried out a study at eight schools and found that fruit consumption (消费) jumped by more than 60 percent when apples were served sliced. They then made a follow-up study at six other schools, which not only showed the same result, but further supported. The whole apple consumption at schools that served sliced apples reduced by about 50 percent than before.Based on these results, it seems that even the simplest forms of inconvenience can influence us. Sliced apples just make more sense for kids. The hardest part is getting kids to start eating fruit, and that’s exactly why sliced apples are the way to go. A child holding a whole apple has to break the skin, eat around the core (果核), and deal with the inconvenience of holding a large fruit. These problems might seem silly or unimportant, but they’re important when you’re missing teeth or have braces (牙箍), as so many kids do.Sometimes what seems like a really small inconvenience actually makes a huge difference.12. What can we learn from Paragraph 1?A. Lots of apples served to kids were wasted.B. Researcher supported the lunch program.C. Apples are not the only acceptable fruit for kids.D. The lunch program was well worth spreading.13. What did researchers want to prove?A. Kid didn’t want the fruits.B. Kids favored the whole apples.C. Kids preferred to the sliced apples.D. Kid’s eating habits influenced fruit consumption.14. According to the study, we can know________.A. 14 schools served sliced fruitsB. kids have problems eating the whole applesC. eating fruits must be healthy for childrenD. few kids are missing teeth or have braces15. What’s the main idea of the passage?A. Form matters more than taste.B. Apples are beneficial to each kid.C. The way fruit is eaten links kids’ growth.D. Inconvenience probably makes a difference.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。
2020年深圳外国语学校高中部高三英语期中考试试题及答案解析
2020年深圳外国语学校高中部高三英语期中考试试题及答案解析第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项AIn his 402nd anniversary year, Shakespeare is still rightly celebrated as a great language master and writer. But he was not the only great master of play writing to die in 1616, and he is certainly not the only writer to have left a lasting influence on theater.While less known worldwide, Tang Xianzu is considered one of Chinas greatest playwrights and is highly spoken of in that country of ancient literary and dramatic traditions.Tang was born in 1550 inLinchuan,Jiangxiprovince. Unlike Shakespeare's large body of plays,poems and sonnets (十四行诗), Tang wrote only four major plays: The Purple Hairpin, Peony Pavilion (《牡丹亭》), A Dream under the Southern bough, and Dream of Handan. The latter three were constructed around a dream narrative, a way through which Tang unlocked the emotional dimension of human desires and ambitions and explored human nature beyond the social and political limits of that time.Similar to Shakespeare, Tang's success rode the wave of a renaissance (复兴) in theater as an artistic practice. As in Shakespeare'sEngland, Tang's works became hugely popular inChinatoo. During Tang'sChina, his plays were enjoyed performed, and changed. Kunqu Opera, a form of musical drama, spread from southernChinato the whole nation and became a symbol of Chinese culture. Combining northern tune and southern music, kunqu Opera was known for its poetic language, music, dance movements and gestures. Tang's works benefited greatly from the popularity of kunqu Opera, and his plays are considered classics of kunqu Opera.While Tang and Shakespeare lived in a world away from each other, there are many things they share in common, such e humanity of their drama, their heroic figures, their love for poetic language, a lasting popularity and the anniversary during which we still celebrate them.1. Why is Shakespeare mentioned in the first paragraph?A. To describe Shakespeare's anniversary.B. To introduce the existence of Tang Xianzu.C. To explain the importance of Shakespeare.D. To suggest the less popularity of Tang Xianzu.2. What's possibly one of the main theme of Tang's works?A. Social reality.B. Female dreams.C. Human emotions.D. Political environment.3. What does the author mainly tell us in Paragraph 4?A. The influence of Kunqu Opera on Tang's works.B. Tang's success in copying Shakespeare's styles.C. The way Kunqu Opera became a symbol of Chinese culture.D. Tang's popularity for his poetic language and music.BFairy tales perform many functions. They entertain, encourage imagination and teach problem—solving skills. They can also provide moral lessons, highlighting the dangers of failing to follow the social codes that let human beings coexist in harmony. Such moral lessons may not mean much to a robot, but a team of researchers at Georgia Institute of Technology believes it has found a way to use the fairy tales as moral lessons that AI (artificial intelligence) can take to its cold, mechanical heart.The collected stories of different cultures teach children how to behave in socially acceptable ways with examples of proper and improper behavior in fables, novels and other literature. We believe story comprehension in robots can prevent the intelligent robots from killing humanity which was predicted and feared by some of the biggest names in technology including Stephen Hawking and Bill Gates. This system is called “Quixote” (堂吉诃德). It collects story plotsfrom the Internet and then uses those stories to teach robots how to behave.The experiment done by the designers involves going to a drugstore to purchase some medicine for a human who needs to get it as soon as possible. The robot has three options. It can wait in line; it can interact with the store keeper politely and purchase the medicine with priority; or it can steal the medicine and escape. Without any further directives(指令), the robot will come to the conclusion that the most efficient means of obtaining the medicine is to steal it. But Quixote offers a reward for waiting in line and politely purchasing the medicine and a punishment for stealing it. In this way, the robotwill learn the moral way to behave on that occasion.Quixote would work best on a robot that has a very limited function. It’s a baby step in the direction of teaching more moral lessons into robots. We believe that AI has to be trained to adopt the values of a particular society, and in doing so, it will strive to avoid unacceptable behavior. Giving robots the ability to read and understand our stories may be the most efficient means.4. What function do fairy tales perform in the robots?A. They entertain robots.B. They highlight dangers.C. They make robots more intelligent.D. They enable robots to behave morally.5. What is “Quixote” in the text?A. A punishment systemB. A character in literatureC. A big name in technologyD. A software educating robots.6. What does the designer expect robot to do in the experiment?A. To take advantage of its privilege.B. To finish the task most efficiently.C. To perform in a good mannered way.D. To be rewarded by the storekeeper17. Which of the follow can bestexpress the author’s opinion?A. Robots will definitely have more functions.B. Robots with human’s emotions are perfect.C. Training robots to be socially acceptable is necessary.D. The development of robots is still in a baby step.CIn Japan many workers for large corporations have a guarantee of lifetime employment. They will not be laid off during recessions or when the tasks they perform are taken over by robots. To some observers, this is capitalism at its best, because workers are treated as people not things. Others see it as necessarily inefficient and believe it cannot continue if Japan is to remain competitive with foreign corporations more concerned about profits and less concerned about people.Defenders of the system argue that those who call it inefficient do not understand how it really works. In the first place not every Japanese worker has the guarantee of a lifetime job. The lifetime employment system includes only “regular employees.” Many employees do not fall into this category, including all women. All businesses have many part time and temporary employees. These workers are hired and laid off during the course of the business cycle just as employees in the United States are. These “irregular workers” make up about 10 percent of the nonagricultural work force. Additionally, Japanese firms maintain some flexibility through theextensive use of subcontractors. This practice is much more common in Japan than in the United States.The use of both subcontractors and temporary workers has increased markedly in Japan since the 1974-1975 recession. All this leads some people to argue that the Japanese system really is not all that different from the American system. During recessions Japanese corporations lay off temporary workers and give less business to subcontractors. In the United States, corporations lay off those workers with the least working experience. The difference then is probably less than the term “lifetime employment” suggests, but there still is a difference. And this difference cannot be understood without looking at the values of Japanese society. The relationship between employer and employee cannot be explained in purely contractual terms. Firms hold on to the employees and that employees stay with one firm. There are also practical reasons for not jumping from job to job. Most retirement benefits come from the employer. Changing jobs means losing these benefits. Also, teamwork is an essential part of Japanese production. Moving to a new firm means adapting to a different team and at least temporarily, lower productivity and lower pay.8. According to the passage, a woman in Japan _________.A. cannot get a lifetime jobB. is impossible to get a part time jobC. will be employed for lifeD. is among the regular workers9. Which of the following is NOT the reason why Japanese workers stay with one firm?A. They don’t want to lose their retirement benefits.B. They are not adaptable people.C. Any change of jobs will make them less paid.D. They get used to the teamwork.10. It can be inferred from the passage that _________.A. those who want to change jobs frequently in Japan should think twiceB. those who are first laid off by American corporations are temporary workersC. the use of subcontractors makes Japanese firms less flexibleD. the Japanese system is totally different from the American system11. What does the passage mainly discuss?A. The extremely hard situation during recessions.B. The extensive use of subcontractors in Japan.C. The characteristics of corporations in the United States.D. The features of lifetime employment in Japan.DA teenager in Georgia will no longer have to walk 7 miles to work after school thanks to one woman’s act ofkindness.Jayden Sutton, a high school senior, went on foot each day from school to his job at a restaurant and then back home. Sutton was determined to work and make enough money to eventually buy his own vehicle.Sutton said he’d leave school at 3:30 pm, then walk miles to his job at the restaurant. After his work, which usually lasted six to eight hours, he walked home, sometimes not arriving back until almost midnight.That all changed when Myers saw him walking down the road in the rain in December. “The young man was insistently in a rush walking to work, saying ‘I can’t be late,’” Myers said. “He begged me to give him a ride. I told him I could take him as far as I was going. I began to create small talk along the way. It wasrevealedto me that his name was Jayden, 12th grader, worked 40 hours a week, walked 5 miles to work immediately after school, got off at 10:30 pm at night and walked back home another 5 miles if co-workers didn’t offer a ride.”After dropping Sutton off, Myers said his heart and determination filled her with tears. “He was smiling in good spirits and that’s a child worth blessing,” she told Fox News. So, Myers shared Sutton’s story on the GoFundMe page, which raised more than $ 9, 000 from 186 donors.She surprised Sutton with a new car after she managed to convince the general manager to drop the price of the vehicle to meet the budget.12.

Had I not seen three bears and a few wolves over the last couple of days near the road, I might have just lain down and called it quits. What in the world was I thinking, dragging my bike up to Yellowstone and thinking I could ride from West Yellowstone to Old Faithful in the snow? No less!I had planned this trip for more than two months, and I wasn't about to give up so easily. The first few miles were beautiful. Ten miles in, I started sucking wind. Fifteen miles and my legs felt like they were made of lead. By twenty miles, my lungs were burning and felt like there was nothing left in the tank. That was when I turned around and saw my husband and three children cheering me on in the van behind me. I knew I couldn't quit because I tell my children all the time that just because something is hard doesn't mean that you stop doing it. I had to live what I'd been preaching(说教). That thought got me up that mountain and to the end of the ride.The importance of that ride was apparent after only a week. My eight-year-old daughter Emalee wanted to ride in a twelve-mile charity ride. That day was cold as well. She was the youngest rider. About four miles into the ride, she started feeling cold. The chill(寒冷)was making her muscles cramp a little and she began to struggle. By six miles, she had tears running down her face. It broke my heart to see her suffering like that.I told herthat she didn't have to finish. She said that she wouldn't quit. I told her how I had wanted to quit the week before, but perseverance had gotten me to the end and I knew she could do it, too.The look on her face as she pulled into the finish was priceless. She threw her arms around me and said, “You didn't quit, Mommy, so neither did I.”1. What motivated the author to finish her ride?A. Her family's encouragement.B. Her own instruction for children.C. The beautiful scenery and weather.D. The careful and thorough preparation.2. By describing the conditions Emalee met, the author wanted to________.A. show her guilt for her daughterB. prove that riding is a tough taskC. persuade her daughter to give upD. indicate she was proud of Emalee3. What does the author want to tell us according to the story?A. Never say die.B. Do nothing by halves.C. Children are what the mothers are.D. Every mother's child is handsome.BIn many countries of the world, people can confidently tell youthe meaning of their town or city, but most people who live inManchester,OxfordorBirminghamwould not be able to explain what the name of their city means. The name of every British town and city, however, has a long history.Two thousand years ago, most people living inBritainwere Celts. Even the word “Britain" is Celtic (凯尔特语).Then the Romans arrived and built camps which became cities called “castra". This is why there are so many place names inEnglandwhich end in "-chester" or “-caster"Manchester, for example.The Romans never reachedWalesorScotland, and many placenames there are Celtic. For example,Welsh place names that begin with “Llan" come from the Celtic word for "church".After the Romans leftBritain, it was attacked by the Anglo-Saxons who were from the area of Europe that is nowGermanyandHolland. The names of their villages often ended in “-ham" or “-ton". Some got their names from the leader of the village.SoBirminghamfor example, means "Beormund's village”The Anglo-Saxons were farmers and the landscape was very important to them, so we have villages called Upton (village on a hill)——a good place to build a village and Moreton (“village by a lake”)where floods could make life hard. Place names that end in “-ford" (a place where you could cross a river) also describe the location of Anglo-Saxon villages.Finally, in 1066EnglandbecameNorman—theNormansgave us the place name "grange", which means farm.And how aboutLondon? Experts cannot agree. The Romans called the city Londinium, but they were not the first inhabitants (居民). People once believed that theUnited Kingdom’s capital city got its name from the castle of a King called Lud but this is very unlikely. Our best guess today is that the name comes from a Celtic word meaning a fast-flowing river. Like a number of British place names, its history is lost in time.4. The origin of British place names is unfamiliar to many local people because ofA. the death of local languagesB. the long lost history of the namesC. their lack of interest in itD. the frequent changes to the names5. According to the article,Stratfordis most likely a town .A. on a hillB. near a castleC. beside a riverD. with a church6. Which of the following shows the correct order of the arrival of inhabitants inBritain?A. The Celts—The Romans—TheNormans—The Anglo SaxonsB. The Celts—The Romans—The Anglo Saxons—TheNormansC. The Romans—The Celts—The Anglo Saxons—TheNormansD. The Romans―The Anglo Saxons—The Celts—TheNormans7. What doesLondonmean in Celtic?A. RiverB. LondiniumC. LudD. CastleCIn a recent survey of 2000 Americans, housecleaning was shown to have some mood-boosting effects — but that doesn't mean everybody is willing to do it.The majority of respondents (受访者) said cleaning gave them a sense of accomplishment (65%) and helped them clear their mind (63%). Half of these adults said they are most often motivated to clean when they're happy. In fact, 63% of those surveyed find the experience of cleaning to be relaxing - even more so than getting fresh air (61%).But that's not the only reason people clean. A big 70% admitted that tidying their home was a way of putting off having to do other things, with the average procrastinator (拖延者) using that trick four times a week. The survey showed that 86% of respondents do feel on top of their housework, but the last deep clean of their kitchen happened over a week and a half ago. That's no surprise because the kitchen is most terrible of all.Conducted by OnePoll on behalf of DishFish, the survey investigated people's attitudes toward dirty dishes and how they get through tricky task. More than two-thirds of people (69%) let their dishes pile up between washings with 20% saying “always” letting them be placed in the sink, which left them feeling stressed. More than any other room, the kitchen was rated as “very difficult” to cope with. And most people enjoy cleaning their toilet or taking out the garbage more than washing dishes by hand.How do they get through it? 66% listen to music while they clean. 72% have a best-loved song that they sounded while tidying up their home, with “Uptown Funk,”“Read All About It” and “Work” being the three favorite tunes on America's cleaning playlist.8. What is the result of the survey?A. Housecleaning may contribute to a good mood to some extent.B. Housecleaning may strengthen people's willingness to volunteer.C. Housecleaning may cause anxiety and concern for some people.D. Housecleaning may improve people's motivation to other housework.9. What is the top reason why people undertake housecleaning?A. They can entertain themselves.B. They can take in fresh air.C. They get a sense of achievement.D. They can delay other things.10. What are respondents' attitudes to dirty dishes?A. Many would rather wash dishes than throw out the rubbish.B. Half are under pressure with dirty dishes lying in the sink.C. A quarter will let dirty dishes pile up after their meals.D. Most prefer cleaning their toiletto washing dishes by hand.11. What column does the text belong to?A. Feature Story.B. Family Life.C. Scientific Hotspot.D. Finance Focus.DWhere doyou usually put your toothbrush?Do you keep it in the bathroom? How’s your toothbrush looking these days? Even if you can’t see it with a naked eye, experts say it may be saturated(使饱和)with millions of toilet germs!Dr. Charles Oerba, a germ expert, is amicrobiology professor at the University of Arizona. He says there are approximately 3 million bacteria per square inch in most toilet bowls, and every time you flush it without closing the lid, those millions of bacteria droplets spray into the air as far as twenty feet away and dirty everything in theirpath. And a common victim is your poor toothbrush, usually, left out on the bathroom sink, right?So, what do we do? Dr. Gerba says it’s easy. Close the toilet lid before you flush—that’ll greatly cut downthe germs, which will otherwise float in the air. And wash your toothbrush every few days in mouthwash or peroxide to get rid of any germs hiding in it. You can even put it through the dishwasher to sanitize(消毒)it. And always store your toothbrush in a closed cabinet.Here’s one more tip from Dr. Gerba, who says our kitchen sink is probably dirtier than our toilet. “If an alien came from space and studied the bacterial counts, he probably would conclude he should wash his hands in your toilet and go to the bathroom in your sink.” He says that’s because the kitchen sink is a great place where E. coli(大肠杆菌)to live and grow since it’s wet and damp. Bacteria feed on the food that people put down the drain or—that’s left on dishes in the sink. To reset your sink’s bacteria count back to zero, you’d better regularly wash it with hot water and sanitize yoursink with special chemicals. In fact, you may want to do it every day or before preparing dinner.12. What is the purpose of the text?A. To show how to brush your teeth.B. To tell people the importance of health.C. To warn people of the invisible germs.D. To introduce a microbiology professor.13. What can we learn from Paragraph 2?A. Bathroom sinks are the dirtiest places.B. Bacteria are bad for people’s health.C. Why bacteria spread through the air.D. How bacteria spread in the bathroom.14. What does the underlined word“that”in Paragraph 4 refer to?A. The food.B. The toothbrush.C. The sink.D. The chemical.15. Why does Dr. Gerba mention the example of an alien?A. To tell us a fiction story of an alien studying bacteria.B. To show our kitchen sink may be dirtier than our toilet.C. To teach us how to reset sink’s bacteria count back to zero.D. To prove coli prefers to live in the kitchen and the drain.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

2020届深圳外国语中学高三英语期中试题及参考答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项ASpeaking with people on the phone is pretty rare these days. Most people use e-mail or messaging apps when they need to communicate with someone. Sometimes, though, making a call is unavoidable. This simple act can actually be a nightmare for some people. Their hearts race and their hands sweat at the very thought. If this sounds familiar to you, you might be one of the millions of people who suffer from telephobia—the fear of speaking over the phone.Telephobia is a form of social anxiety, although people who feel perfectly comfortable in social situations may also experience telephobia. When speaking face-to-face, we give off lots of facial or bodily cues that help each other follow the conversation. This is not the case over the phone. And the idea of speaking into this void（真空）makes people terrified that they will freeze up, stumble over their words（失言）, or lose control of the conversation and look foolish In fact, telephobia is very similar to thefear people feel before putting on a performance in front of a big audience. However, there are things that one suffering from thin condition can do to reduce this fear and make phone calls at least somewhat bearable.One thing that those with telephobia can do before a call in smile. It may sound silly, but smiling before doing something stressful can help you feel more relaxed. It won't delete the anxiety altogether, but it will take the edge off it.Similarly, imagining how the call will go before you make it can also help things go more smoothly. Running through a positive conversation in your head will make you feel less nervous and may help you predict any possible problems. There's no need to spend hours on this, just a few minutes thinking up a general idea of what you want to say. You can even write down some brief notes to remind yourself of your talking points. This is particularly useful for dealing with the fear of not being able to express yourself naturally.And finally, when faced with receiving a call, you don't always have to pick up. There's nothing wrong with calling the person back later when you feel more comfortable.So the next time your phone starts ringing, remember—speaking on the phone doesn't have to make you sweat. The important thing is to be aware of your fear and take steps to deal with it.1. According to the article, which situation can cause a feeling similar lo telephobia?A.Speaking face-to-face to a good friend.B. Performing in front of a large audience.C. Running in a race without proper shoes.D. Using a messaging app while on the subway.2. Which of the following is NOT mentioned as a way to deal with telephobia?A.Imagining how the call will go before you make it.B. Standing on the edge of a tall building while making a call.C. Calling someone back later instead of answering their phone calls right away.D. Writing down some brief notes to remind yourself of your talking points.3. What is the main purpose of the passage?A. To present ways to ease telephobia.B. To explain the development of telephobiaC. To introduce the influence of telephobia.D. To give the reason why someone suffers from telephobia.BA team of engineers atHarvardUniversity in trying to create the first robotic fly. Designed to do what a fly does naturally, the tiny is the size of a fat housefly. Its mini wings allow it to stay in the air and perform controlled flight tasks."The added difficulty with a project like this is that actually none of its components is off the shelf and so we have to develop them all on our own’ said Robert Wood, a Harvard engineering professor.They engineered a series of systems to start and drive the robotic fly. “The seemingly simple system which just moves the wings hasa number of interdependencies (相互依赖）on the individual components, each of which individually has to perform well, but then has to be matched well to everything it d connected to,” said Wood.While this first robotic flyer is linked to a small, off-board power source, the goal is eventually to equip it with a built-in power source, so that it might someday perform data-gathering work at rescue sites，in farmers’ fields or on the battlefield. "Basically it should be able to take off, land and fly around，” he said.Wood says the design offers a new way to study flight mechanics and control at insect-scale. Yet, the power, sensing and computation technologies on board could have much broader applications.“You can start thinking about using them to answer open scientific questions, you know, to study biology in ways that would be difficult with the animal，but using these robots instead” he said. "So there are a lot of technologies and open interestingscientific questions that are really what drives us on a day-to-day basis.”4. What is the typical characteristic of the robotic fly?A. It's automatic.B.It's very small.C. It's controllable.D. It's quite powerful.5. We can infer from the passage that the robotic flyer can____ .A. act as a spy planeB. help do farm workC.fly at a very high speedD. answer many scientific questions6. What is Wood's idea about the robotic fly according to the last paragraph?A. It is highly questionable.B. It has wide practical applications.C. It gives scientists interest in flying machines.D. It points to a new direction in studying biology.7. What can be the best title for the passage?A. Harvand's Study in the Field of Insects.B. A Breakthrough in Engineering ScienceC. An Interesting Invention一Robotic FlyD. Robotic Fly一a Copy of Real Life InsectCThe Chinese philosopher (哲学家) Confucius once said, “Time flows away like the water in the river.” This is especially true as the novel coronavirus pneumonia outbreak has affected millions of people in China, andthe whole nation has been working day and night to fight the epidemic.In late January, when an increasing number of people in Wuhan were suspected to be infected, and hospitals didn't have adequate beds for them, two special hospitals—Lei shenshan Hospital and Huo shenshan Hospital were built. These two makeshift (临时的) hospitals were built to treat pneumonia patients infected with the novel coronavirus.HuoshenshanHospitalhas 1,000 beds and covers 33,900 square meters, andLeishenshanHospitalhas 1,500 beds and a total area of about 79,000 square meters. More than 4,000 workers worked 24/7 in two shifts, and nearly 1,000 large-scale pieces of equipment and transport vehicles helped the project on site. The two hospitals were built in an amazingly short time. It only took 10 days for people to build Huo shenshan, and 14 days for Lei shenshan.This certainly wowed many people overseas. “It's incredible that two hospitals with 2,500 beds can be built ina short period. It's just hard to believe,” a foreigner named Stuart told People's Daily. In the meantime, Chinese companies have also taken actions quickly in this battle.“The automobile industry is highly industrialized with strong capabilities in comprehensive manufacturing, purchasing materials, production lines and output of technologies,” Shi Jianhua, deputy secretary-general of China Association of Automobile Manufacturers, told CCTV News. “In this special time, when the nation needs more masks, it's time for us to quickly respond and shoulder the social responsibilities.”Indeed, a fast response is crucial in any crisis. In this special time,Chinacan't afford to waste a second in the fight against the epidemic. After all, time equals life during this crisis.8. Confucius' saying “Time flows away like the water in the river.” is mentioned to ______.A. arouse readers' interest in the passage.B. introduce the subject of the passage.C. present the background information.D. stress the value of time in epidemic.9. What can we learn about Lei shenshan hospital and Huo shenshan hospital?A. They are new hospitals for health care inWuhan.B. They were built in minimal time.C. Over 4,000 workers worked continuously.D. Stuart found them too massive to believe.10. We can infer from Shi Jianhua's words that the automobile industry inChina______.A. had no medical supplies factories before.B. guarantees whoever in need enough masks.C. has capabilities to give timely response.D. has strong abilities in manufacturing.11. What does the passage mainly talk about?A. China fights epidemic against the clock.B. Twospecial hospitals were constructed.C. Chinese firms acted quickly and effectively.D. Time is crucial for people in overcoming crisis.DWhena person in the United States gets the COVID-19 vaccine (疫苗), the person receives a small piece of paper called a “COVID-19 Vaccination Record Card”.It is a piece of paper with the logo of the Centers for Disease Control and Prevention, or CDC, and the nameand date of the vaccine. Because it is so simple, it could be easy to fake.Many people in theU.S.are still unsure about getting the vaccine. As universities, workplaces and other places are requiring proof of vaccination, some people are now buying fake vaccination cards without getting a shot.The Associated Press reports that students and teachers at universities around theU.S.are worried about fake cards. Sellers are using social media apps like Instagram to advertise fake vaccination cards. The prices range from $25 to $200. The AP notes that many college students seem interested in buying the cards. On the site Reddit, one person wrote, “I need one, too, for college. I refuse to be a guinea pig.”It is reported that more than 700 universities and colleges require proof of vaccination. Most schools simply ask their students to take a photo of their card and send it to a school website. Benjamin Mason Meier is a professor at theUniversityofNorth CarolinaatChapel Hill, UNC. He studies international health policy. He said, unlike some countries, theU.S.is not using a digital system to record vaccine status. He said theU.S.is depending on “aflimsypaper card”, and students have told him they knew of others who had used fake vaccination cards. Rebecca Williams also works at UNC. She is a researcher at the school’s Center for Health Promotion and Disease Prevention. She said she was not surprised that people were worried about fake vaccination cards. “This is why I think the development of a reliable national digital vaccine passport app is very important,” she said.There is a law that should prevent people from making false vaccination cards. If someone uses the CDC logo without permission, they can be lined and punished by up to five years in prison. The U.S. Department of Justice recently charged a person inCaliforniawith making fake vaccination cards.College students who already have the vaccine are criticizing those who would rather spend money to buy a fake than get a free shot. Maliha Reza is an electrical engineering student atPennsylvaniaStateUniversity, She called those students “dumb”. “I’m angry about that,” she said. “Like, there is more anger than I could describe now.”12. Why do some college students buy fake vaccination cards?A. They are easy to get.B. Many Americans are still uncertain about getting the vaccine.C. Students have an interest in the fake vaccination cards.D. To get a vaccine shot is expensive.13. Which of the following measures can NOT be used to stop the fake cards?A. Having a law that should prevent people from making false vaccination cards.B. Developing a reliable national digital vaccine passport app.C. Using a digital system to record vaccine status.D. Having all the students take a photo of their vaccination card and send it to the school website.14. What does the underlined word “flimsy” probably mean?A. Weak.B. Effective.C. Detailed.D. Professional,15. What might be the writing purpose for the news report?A. To promote a digital system to record the vaccination shots.B. To explain why theU.S.should prevent making the fake vaccination cards.C. The stress the influence of the COVID-19 vaccination.D. To reduce theU.S.university leaders’ worry about fake vaccination cards.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

2020届深圳外国语学校初中部高三英语下学期期中考试试卷及答案解析第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项AElectric Shocks Can Be FatalGovernment statistics recently showed that in theUK, more than 3,000 people a year experience electric shocks in their homes. A smaller number of people are killed after they touch the power lines outside their homes. Electric shocks can cause a person's heart or breath to stop and are potentially fatal. It is essential for people to learn basic techniques to deal with such emergencies.What to do?● If you are the first person to reach someone who has an electric shock, don't touch him or her!● If the victim is still holding the appliance that gives him or her the shock (e.g. a hair dryer), unplug it or turn off the power at its source.Under no circumstances can you try to move the appliance with your hands!● Ifyou can't turn off the power, use a piece of wood, like a broom handle or a chair, to separate the victim from the appliance or the power source. You may even be able to do this with a folded newspaper.● The victim must remain lying down. If he or she isunconscious, the victim should be placed on his or her side. But he or she should not be moved if there is a possibility of neck or spine injuries unless it is ly necessary.● It is essential to maintain the victim's body heat, so make sure you cover him or her with a blanket before you do anything else. If the victim is not breathing, apply mouth-to-mouth resuscitation (人工呼吸). Keep the victim's head low until professional help arrives.● If the electric shock has been caused by an external power line, the dangers to the victim and to anybody providing first aid are much greater.1. What kind of passage is it?A. An advertisement.B. A horror story.C. A news report.D. First aid emergency advice.2. The underlined sentence implies that ________.A. you should move the applianceB. you should pick up the appliance and turn off the electricityC. it is very dangerous to touch the appliance with your handsD. it is unnecessary to unplug the appliance with your hands3. When a person has got an electric shock, you should ________.A. separate the victim from the appliance and let him sit upB. keep the victim warm and help him or her breathe againC. move the victim onto his or her side if he or she has got neck injuriesD. keep the victim's head high until professional help arrivesBSport is not only physically challenging, but can also be mentally challenging. Criticism from coaches, parents and other teammates, as well as pressure to win can create too much anxiety or stress for young athletes. Stress canbe physical, emotional, or psychological and research has indicated that it can lead to burnout. Burnout has been described as dropping or quitting of an activity that was at one time enjoyable.The early years of development are critical years for learning about oneself. The sport setting is one where valuable experiences can take place. Young athletes can, for example, learn how to cooperate with others, make friends, and gain other social skills that will be used throughout their lives. Coaches and parents should be aware, at all times, that their feedback to youngsters can greatly affect their children. Youngsters may take their parents and coaches’ criticisms to heart and find faults in themselves.Coaches and parents should also pay attention that youth sport participation does not become work for children. The outcome of the game should not be more important than the process of learning the sport and other life lessons. In today’s youth sport setting young athletes may be worrying more about who will win instead of enjoying themselves and the sport. Following a game many parents and coaches focus on the outcome and find faults with youngsters’ performances. Positive support should be provided regardless of the outcome. Research indicates that positive support motivates and has a greater effect on learning than criticism. Again, criticism can create high levels of stress, which can lead to burnout.4. An effective way to prevent the burnout of young athletes is_____________.A. to make sport less competitiveB. to increase their sense of successC. to reduce their mental stressD. to make sport more challenging5. According to the passage, sport is positive for young people in that_____________.A. it can help them learn more about societyB. it enables them to find faults in themselvesC. it can provide them with valuable experiencesD. it teaches them how to set realistic goals for themselves6. Many coaches and parents are in the habit of criticizing young athletes_____________.A. believing that criticism does good to their early developmentB. without realizing criticism may destroy their selfconfidenceC. in order to make them remember life’s lessonsD. so as to put more pressure on them7. According to the passage parents and coaches should_____________.A. pay more attention to letting children enjoy sportB. help children to win every gameC. train children to cope with stressD. enable children to understand the positive aspect of sportCShanghairesidents passing through the city’s eastern Huangpu district in Octobermight have astonished at an unusual sight: a “walking” building. An 85-year-old primary school has been lifted off the ground in its entirety and relocated using new technology named the “walking” machine.In the city’s latest effort to preserve historic structures, engineers used nearly 200 mobile supports under the five-story building. The supports act like robotic legs. They’re split into two groups which in turns rise up and down, imitating the human step. Attached sensors help control how the building moves forward.TheLagenaPrimary School, which weighs 7,600 tons, faced a new challenge — it’s T-shaped, while previously relocated structures were square or rectangular. Experts and technicians met to discuss possibilities and test a number of different technologies before deciding on the “walking machine”.Over the course of 18 days, the building was rotated 21degrees and moved 62 meters away to its new location. The old school building is set to become a center for heritage protection and cultural protection. The project marks the first time this “walking machine” method has been used inShanghaito relocate a historical building.In recent years,China’s rapid modernization has seen many historic buildingsrazedto clear land for skyscrapers and office buildings. But there has been growing concern about the architectural heritage loss as a result ofdestruction across the country.Shanghaihas beenChina’s most progressive city when it comes to heritage preservation. The survival of a number of 1930s buildings in the famous Bund district and 19th-century “Shikumen” houses in the repaired Xintiandi neighborhood has offered examples of how to give old buildings new life. The city also has a track record of relocating old buildings. In 2018, the city relocated a 90-year-old building in Hongkou district, which was then considered to beShanghai’s most complex relocation project to date.8. How did the primary school get moved?A.

I was born two weeks late. When I finally entered the world I weighed 11 pounds 10 ounces and was 24 inches long. When my mom told my grandmother my measurements, she asked in amazement, "Are you okay?!"I was healthy, but very shy as a child and into my teens. I'm from a small town, and I grew up and graduated with the same 50 people. I started playing basketball in third grade every Saturday, but I didn't have any control over my awkward body. (I didn't even score a point in a game until many years later.) I was 5-foot-10 in fourth grade. I had a small group of friends in elementary school, but sometimes the boys picked on me, calling me a bean pole or the Jolly Green Giant. I still remember my embarrassment when they laughed at me, and how badly I wanted to be invisible.In high school I got more involved in sports, but I spent most days in the art room. By this time everyone at my school was used to my height (by ninth grade I was 6-foot-3), but if I went out of town people would stare at me and comment about my appearance.I was forced into the spotlight wherever I went.With high school came more confidence. I had success in school, the arts and sports. I played basketball, but my true passion was track and field. During my senior year I was the conference champion in high jump and the 400-meter run. The friendships I gained through my involvement in high school boosted my confidence and helped me develop a sense of humor. Now when a stranger told me I was tall I would smile and nod or, if I was feeling determined, I would pretend to feel shocked and thank them for telling me. I had no idea!Still, society keeps me aware of my status as something rare. And even though people tell me I'm beautiful and I should be a model, there are times when I would trade in my long legs for a small frame and tiny feet. I often wish people weren't so rude. I'm a minority only in the sense of height. I like to think that those who have insulted me didn't intend to. I do believe that most people are basically good, but they can be insensitive.12. What can be inferred from Para.1?A. The writer's height has something to do with her late birth.B. Grandmother was unwilling to have the writer as her grandchild.C. The writer failed to have a successful life because of her unusual height.D. The writer was heavier and bigger compared with other babies when she was born.13. By saying 'I was forced into the spotlight', the author probably means that she ________.A.was criticized by othersB. caught public attentionC. was threatenedD. felt inferior14. Which of the following statements is NOT mentioned as the writer's experiences in high school?A. She quit playing basketball and joined the track and field team.B. She no longer felt upset when facing her height problem.C. She had a passion for some sports events.D. She built up more confidence.15. What does the last sentence imply?A. People enjoy making fun of others.B. People are bad andcannot be trusted.C. People tend to bully those who are weaker.D. People sometimes care little about how others feel.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

The Memorial of the Site of the First National Congress of the CPC.BAbout a month after I joined Facebook, I got a call from Lori Goler, a highly regarded senior director of marketing at eBay. She made it clear this was a business call. “I want to apply to work with you at Facebook,” she said. “Instead of recommending myself, I want to ask you: What is your biggest problem, and how can I solve it?”My jaw hit the floor. I had hired thousands of people over the previous decade and no one had ever said anything remotely like that. People usually focus on finding the right role for themselves, with the implication that their skills will help the company. Lori put Facebook’s needs front and center. It was a killer approach. I responded, “Recruiting is my biggest problem. And, yes, you can solve it.”Lori never dreamed she would work in recruiting, but she jumped in. She even agreed to trade earnings for acquiring new skills in a new field. Lori did a great job running recruiting and within months was promoted to her current job, leading People@Facebook.The most common metaphor for careers is a ladder, but this concept no longer applies to most workers. As of 2010, the average American had eleven jobs from the ages of eighteen to forty-six alone. Lori often quotes Pattie Sellers, who came up with a much better metaphor: “Careers are a jungle gym, not a ladder.”As Lori describes it, there’s only one way to get to the top of a ladder, but there are many ways to get to thetop of a jungle gym. The jungle gym model benefits everyone, but especially women who might be starting careers, switching careers, getting blocked by external barriers, or reentering the workforce after taking time off. The ability to create a unique path with occasional dips, detours (弯路), and even dead ends presents great views of many people, not just those at the top. On a ladder, most climbers are stuck staring at the butt of the person above.4. Why did Lori make the call?A. She helped Facebook to solve the biggest problem.B. She wanted to make a business deal with Facebook.C. She tried to ask for a pay rise in Facebook.D. She wanted to become an employee in Facebook.5. What impressed “I” by Lori?A. Lori was good at running recruiting.B. Lori attached great importance to Facebook’s needs.C. Lori jumped in Facebook with no adequate experience.D. Lori was skilled in marketing at eBay.6. What can we infer from the passage?A. Now all people don’t tend to climb the ladder.B. None on the ladder can enjoy the great views.C. Jungle gyms offer limited exploration for employees.D. A pregnant woman, jobless, benefits little from the jungle gyms.7. What is the best title of the passage?A. It’s a Jungle Gym, Not a Ladder.B. Facebook’s Biggest Problem.C. Applying for a Job in Facebook.D. A Jungle Gym is Better than a Ladder.CWilliam had worked hard to pass the exams to enter high school. When the term began, however, his father told him that there was no money to pay for his school fees because of the summer drought. Still, William wanted to learn.He made the village library his school. One day, he found a book calledUsing Energy. On the book’s cover wasa picture of windmills, tall steel towers with blades (叶片) spinning like giant fans. He learned that wind—something of which his hometown had plenty—could produce electricity.He couldn’t help picturing his own windmill in mind, but collecting the parts and tools he needed would take months. In a junkyard, he dug through piles of used metal, old cars, and worn-out tractors, searching for anything that might help him construct his machine. He made four-foot-long blades from plastic pipe, which he melted over a fire, flattened out, and hardened with bamboo poles.Earning some money, he paid a blacksmith to attach the piston (活塞) to the pedal sprocket (踏板链轮) of an old bicycle frame. This would be the axle (轮轴) of the windmill. When the wind blew, the spinning blades would turn the bicycle wheel and spin a small dynamo (发电机), donated by his friend.When he had collected all the parts, William began putting them together. He fixed the blades to the tractor fan he found, using washers (垫圈) he’d made from bottle caps. Next he pushed the fan onto the piston joint to the bicycle frame. With the help of his two best friends, Williambuilt a 16-foot-tall tower from trunks of trees and lifted the ninety-pound windmill to the top.The big moments eventually came. He climbed up the tower and connected two wires that held a small bulb. As the wind whipped around him, the blades began to turn, slowly at first, then faster and faster. The light bulb flickered (闪烁), then flashed to life. The crowd cheered from below. “Wachitabwina (well done)!”William’s machine now powered his house. And the story of the boy who’d built a power-generating windmill to rescue his family from the drought spread across the Internet.8. After readingUsing Energy, what did William decide to do?A. Make use of wind.B. Enter a high school.C. Build a village library.D. Learn to survive a drought.9. According to Para.3, which of the following word can best describe William?A. Humorous.B. Determined.C. Cooperative.D. Friendly.10. What can you learn about William’s machine?A. It was built by villagers.B. It worked at the first attempt.C. It took him years to complete it.D. It was made from metal materials.11. What is the besttitle for the passage?A. Winds Of HopeB. Ideas Worth SpreadingC. Learning from ExperienceD. Windmills for VillagesDTyphoons can be deadly — in 2013, Typhoon Haiyan, the strongest ever recorded, was responsible for 6,340 deaths—and cost billions in damages. Current forecast modelscan only predict these storms 10 days in advance, at most, and they cannot precisely predict how intense the storms will become.An international team of researchers has developed a model that analyzes nearly a quarter of Earth’s surface and atmosphere in order to better predict the conditions that birth typoons.“The target problem of this study is how to foretell the birth of typhoons,” said paper author Mingkui Li, associate professor in the Key Laboratory of Physical Oceanography in the Ocean University of China and the Pilot National Laboratory for Marine Science and Technology (QNLM). “We specifically address three aspects: the beginning time, inner pressure and maximum wind speed.”The researchers also accounted for the influence of one variable(变量) on another, such as wind speed on sea surface temperature. This influence is well understood and accounted for in climate predictions and in weather forecasts, butithas not been fully applied in understanding how long-term climate affects day-to-day weather, according to Li. “We aimed to provide insights on the time scale that can be used to forecast typhoons in advance.”From their study, the researchers determined that a model with the ability to better understand the relationship between warm sea surface temperatures and weak wind movement— conditions that favor typhoon formation—could improve typhoon predictability.“Our goal is to develop a 10 to 30-day prediction system that will lead to seamless(无缝的) weather-climate predictions.” Shaoqing Zhang, paper author and professor in the Key Laboratory of Physical Oceanography, said.12. What is the problem with the present forecast system?A. It cannot foretell storms in advance.B. It is ineffective in accuracy and timeliness.C. It costs too much and causes great damages.D. It can hardly predict the intensity of typhoons.13. What does the underlined word “it” in paragraph 4 refer to?A. The variable.B. The climateC. The temperature.D. The influence.14. What is the purpose of the study?A. To advance the prediction system.B. To figure out the three main aspects.C. To know how climate affects daily weather.D. To understand the influence of the variables.15. Where is this text most likely from?A. Awork diary.B. A travel guidebook.C. A science magazine.D. A fantasy fiction.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

2020年深圳福田外国语学校高三英语下学期期中试题及参考答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项ARome can be pricey for travelers, which is why many choose to stay in a hostel (旅社). The hostels in Rome offer a bed in a dorm room for around $25 anight, and for that, you’ll often get to stay in a central location (位置) with security and comfort.Yellow HostelIf I had to make just one recommendation for where to stay in Rome, it would be Yellow Hostel. It’s one of the best-rated hostels in the city, and for good reason. It’s affordable, and it’s got a fun atmosphere without being too noisy. As an added bonus, it’s close to the main train station.Hostel Alessandro PalaceIf you love social hostels, this is the best hostel for you in Rome. Hostel Alessandro Palace is fun. Staff members hold plenty of bar events for guests like free shots, bar crawls and karaoke. There’s also an area on the rooftop for hanging out with other travelers during the summer.Youth Station HostelIf you’re looking for cleanliness and a modern hostel, look no further than Youth Station. It offers beautiful furnishings and beds. There are plenty of other benefits, too; it doesn’t charge city tax; it has both air conditioning and a heater for the rooms; it also has free Wi-Fi in every room.Hotel and Hostel Des ArtistesHotel and Hostel Des Artistes is located just a 10-minute walk from the central city station and it’s close to all of the city’s main attractions. The staff is friendly and helpful, providing you with a map of the city when you arrive, and offering advice if you require some.

Former First Lady Michelle Obama worked hard to make school lunches healthier, resulting in new menus that featured less fat and salt, more fruits and vegetables.But high-quality nutrients count for little when there is no time to eat them. Amy Ettinger reports, "There is no national standard on how much time kids get to eat that meal. " And with schools being occupied with test scores, teachers are using every available minute for lesson time, which often leaves kids without enough eating time.This is a problem because the length of the school lunch period is a key factor (因素) in how much nutrition children actually gel. Research has found that having less than 20 minutes for lunch results in children consuming much less of their lunch than those with more than 20 minutes.This is really terrible. For many low-income kids, that cafeteria lunch can represent half their daily energy intake. There's also another terrible message that it's acceptable to wolf down food as fast as possible before rushing off to your next class. Cafeteria time should be a chance to interact with friends, to learn important social skills, to observe and share varieties of food. It should be a break in day, a chance to relax before heading into the afternoon.As Ettinger explains,some parents are hoping the National Parent Teacher Association will address this issue. This, in turn, would help parents push their kids' schools for better lunch time standards. Meanwhile, if you have a kid in this situation, you can help by packing a healthy lunch to spare them the cafeteria lineup. Make the foods easy to eat, provide non-messy snacks that can be eaten in class, put great effort into serving a hearty breakfast, and sit down as a family for dinner whenever possible.4. What did Michelle Obama make efforts to improve?A. The quality of school lunches.B. The performance of school kids.C. The school lunch time kids have.D. The eating habits of school kids.5. What happens to children in American schools?A. They are occupied with many tests.B. They fail to get along with each other.C. They consume more meat than before.D. They have less lunch time than before.6. How are low-income kids influenced by the problem at school?A. They can't go to classes on time.B. They can't have enough energy.C. They can't share different kinds of food.D. They can't hold a positive attitude toward life.7.What can parents do to solve the problem?A. Prepare a better lunch for their kids.B. Stop their kids going to the cafeteria.C. Force schools to make adjustments to lunch.D. Guide their kids on how to pack their own lunch.CInAsia, there are special competitions where kites have complex designs and are fitted with instruments that make musical sounds as the wind blows through them. Although all kites have a similar structure (结构), they are widely different in size and shape. Kite-fighting competitions are also held, in which competitors use their kites to attack and bring down their opponents’ (对手) kites or cut their strings (线).For more than 15 years, the Big Wind Kite Factory has been giving kite-making and kite-flying classes for the children on an island inHawaii. In its kite-making lessons, students can make kites in as little as 20 minutes! Children as young as four years old can learn how to fly a kite. Jonathan Socher and his wife Daphne started the kite factory in 1980. Their kites are made of nylon (尼龙). Their designs are Hawaiian themes created by Daphne. The designs are cut out of the nylon with a hot knife that seals the edges and then fastened directly onto the kite. The kite that is used to give lessons is a regular diamond kite with a rainbow pattern. The difference between this kite and the ones they make during the lessons is that it is a two-string controllable kite. Big Wind employees fly the kite and for a few minutes show students how pulling on one line and then on the other controls the direction the kite goes in. Then the controls are given to the students.Jonathan insists that it is not necessary to make a huge impressive kite to have fun making and flying kites. Even the simplest structure can work, and can give hours of fun. Go on, give it a try!8. Which of the following is true according to the text?A. A hot knife is used to iron the nylon.B. Children never fly kites on their own in flying lessons.C. Kite strings must not be cut in kite-fighting competitions.D. Daphne designs kites for the Big Wind Kite Factory.9. What is different about the kite used for flying lessons?A. It has two strings.B. It is simple in design.C. It has a rainbow pattern.D. It is shaped like a diamond.10. According to Jonathan,what do you need to have fun with kites?A. A large kite.B. Any type of kite.C. A complex structure.D. A kite that impresses others.11. What is mainly described in the text?A. A kite factory.B. Kite-flying lessons.C. Special competitions.D. The kite-making process.D“Snowplow(扫雪机) parenting” is the newest parenting style that can include parents booking their adult children haircuts, calling their college kids to wake them up so that they don’t sleep through a test, and even calling their kids’ employers.“‘Helicopter (直升机) parenting’ means monitoring their kids’ every activity,which is out of date.” Claire Cain Miller and Jonah Engel Bromwich wrote in The New York Times. “Some rich mothers and fathers now are more like snowplows: clearing any problems in their children’s path to success so that they don’t have to meet failure or lose opportunities.”There is a mother who started a charity in her son’s name to try to raise his chances of being accepted to the college. Another parents spent years helping their daughter avoid foods with sauce, which she didn’t like. Once she got to college, she had problems with the food in her school because it was all covered in sauce.A survey says that three-quarters of parents of children between the ages of 18 and 28 ask for doctor visits or haircuts for their children, and 11% say they would call their kids’ bosses whether their children are having an issue at work.As reported, wealthy parents try to get their children into top colleges by giving a large amount of money to a school, such as paying for a building. This parenting has become the most popular way to raise children, whatever the income, education, or race is.Julie, a teacher at Stanford, told the Times that “snowplow parenting” is not a reasonable approach. “The parents should prepare the kid for the road, instead of preparing the road for the kid,” she said.12. How does Julie like “snowplow parenting”?A. It is unreasonable.B. It is advanced.C. It is accepted by teachers.D. It is refused by rich people.13. What is the character of “helicopter parenting”?A. Parents make kids popular.B. Parents provide little money for kids.C. Parents ask kids to care for themselves.D. Parents watch over kids’ every activity.14. What should parents do according to Julie?A. Do as wealthy parents do.B. Make kids be prepared.C. Make roads be prepared.D. Do as little as possible.15. What’s the best title for the text?A. Helicopter Parenting.B. The Similarity in Parenting.C. A Research on Parenting.D. A New Kind of Parenting.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。
2020届深圳外国语学校高三英语下学期期中考试试题及答案
2020届深圳外国语学校高三英语下学期期中考试试题及答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项AIt looks like 2017 is shaping up to be a record-breaking year in movie History. Here is a list of some of the year’s biggest blockbusters so far.Kong: Skull IslandA reboot (重启) of King Kong would normally get laughed at in this day and age, but it looks like this modem version of the story will be worth watching. With US actress Brie Larson and UK actor Tom Hiddleston in the mix, this film is set to be this year’s biggest monster tale.Release Date:3/10/17Beauty and the BeastDirector Bill Condon is bringing back a part of our childhood in live action, complete with the songs we all remember and love. With British stars Emma Watson and Dan Stevens leading thecast, the classic Walt Disney story already sounds like it’ll be a delight for both children and adults.Release Date:3/17/17The Fate of the FuriousThere was doubt that we’d even get a Fast 8, especially after the fitting ending US actor Paul Walker’s character was given at the end of Furious 7. Fans thought they’d never see Dom and the rest of the crew back in action, but thankfully, US star Vin Diesel himself confirmed that The Fate of the Furious is fueling up for another go.Release Date:4/14/17Spider-Man: HomecomingSpider Man is heading home to Marvel Studios for the first time. The movie will show us Peter Parker’s high school days, and will continue the threads we saw formed during his initial appearance in Captain America: Civil War. We know that Michael Keaton is playing The Vulture in this story, and that both Happy Hogan and Tony Stark, played by US actors Jon Favreau and Robert Downey Jr., are along for the ride.Release Date:7/7/171.Which of the following movies can’t you see on May Day?A.Kong: Skull Island.B.Beauty and the Beast.C.The Fate of the Furious.D.Spider-Man: Homecoming.2.What can we know about Beauty and the Beast?A.It is fueling up for another go.B.It is produced by Marvel StudiosC.It’ll show us Peter Parker’s school days.D.It’ll be enjoyable for both children and adults.3.What does the underlined word “cast” probably mean?A.Characters.B.Actors.C.Directors.D.Teachers.BScientists have long sought to prevent sharp memories from dulling with age, but the problem remains unsettled. Now research published in Scientific Reports suggests virtual reality might help older people recall facts and events based on specific details.The study involved 42 healthy older adults from the San Francisco Bay Area. Half spent a dozen hours over four weeks playing a virtual-reality game called Labyrinth; they wore headsets and walked in place, walking virtual neighborhoods while completing small tasks. The other half, in the control group, used electronic tablets to play games that did not require recalling details. After 15 sessions (期), the latter performed roughly the same as before on a long-term memory test. But the Labyrinth players gain an improvement in memory through the VR game. A scientist Peter Wais of the University of California said the improvements brought them up to the level of another group of younger adults taking the same memory tests.Meredith Thompson, an education researcher, studies learning through VR games but was not involved in the new study. It would be great to actually follow people over time and see what this type of game does for long-term memory. She says, adding VR can provide greater involvement than other games. Wais's team is now investigating how long the observed effects last and which elements of the training have the most impact.A cognitive (认知)psychologist, Daniel Simons, who was also not involved in the study, notes experiments with other games that claim to train the brain have often failed to evaluate this. And it remains unclear how test performance in a laboratorysetting might translate to real-world situations. The outcome, Simons notes, “needs to be repeated, ideally with a much larger group, before it’s treated as a strong finding.”For now, Wais says, the team hopes its studies with similar-sized groups will help draw funding to test thegame in a larger pool of participants.4. What is the passage mainly about?A. People's memory gradually fails as they age.B. People of different ages should play VR games.C. Virtual reality changes people's memory.D. Virtual reality improves older adults' memory.5. What is Meredith Thompson's attitude toward the research?A. satisfied.B. enthusiastic.C. cautious.D. concerned.6. According to the scientists, the research needs to be improved due to ________.A. the lack of financial support.B. the limited pool of participants.C. the unsatisfying test performance.D. the impractical application in real world.7. Where may the passage come from?A. A novel.B. A review.C. A magazine.D. A guidebook.CAfter finishing his dinner, Lin Xu opened a WeChat mini-program called "Clear Plate" on his phone and took picture of the empty plates. He was then awarded 157 credit points after the image was uploaded and recognized by artificial intelligence.“Users of the app can use their credit to buy gifts, such as books and cellphones to purchase charity meals donated to children in poor rural areas,” Lin said.A nationwide "Clear Your Plate" campaign is gaining steam online. Efforts to stop food waste and promote thrift are also being made by restaurants that have been urged to create an environment in which consumers are reminded not to waste food. They are also encouraged to offer different portion sizes so that customers can have more choices.The “Clear Plate” mini-program has become popular among young Chinese and currently has nearly 1 million users.Liu Jichen, founder of the startup that developed the app, said that the idea popped up at a dinner in 2017, when Liu found that a restaurant would give diners who polished off their food a card and offer small gifts after a certain number of cards had been collected.“Such an idea can be realized online,” Liu said. He formed a team to work on the project.Yet it was quite challenge for the AI system to identify whether the uploaded photos showed empty plates.To make the AI system smarter, Liu and his team, assisted by more than 1,000 others, spent half a year collecting over 100, 000 samples in canteens and restaurants across the country and used the data to train neural network. Dozens of enterprises, institutions and restaurants have contacted the startup to cooperate on the project.Through the visualized mini-program, people can clearly see the good results of saving food, which will effectively reduce waste, he noted. "We hope our efforts can start a new trend among the younger generation, encouraging them to carry out the virtue of cherishing food and developing the habit of thrift, " Liu said8. What is the main function of the APP "Clear Plate?A. Awarding credit points.B. Giving charity meals.C. Showing the empty plates.D. Encouraging saving food.9. How is the "Clear Your Plate" campaign carried out?A. Customers wasting food are punished.B. People join in it on mini-program.C. Restaurants limit customers' choices.D. People are encouraged to buy gifts.10. What was the most difficult when the app was created?A. Getting other people to cooperate with the team.B. Collecting samples in canteens and restaurants.C. Ensuring the app to recognize empty plates.D. Finding people to fund the app.11. What is the purpose of the writing?A. To introduce an app.B. To promote saving food.C. To praise a startup founder.D. To raise fund for poor children.DIs renting clothes greener than buying them? Sustainable (可持续的) fashion expert Elizabeth Cline isn’t sure. Clothing renting is a hot new industry and businessmen are trying to attract shoppers who care about the environment. Last summer alone,Urban Outfitters, Macy’s, Bloomingdale’s American EagleandBanana Republicall announced renting services – a sure sign of changing times.But is renting fashion actually more environmentally-friendly than buying it? And if so, how much more? Journalist and author Elizabeth Cline researched this question in a feature article for Elle, and she concluded that it’s not as sustainable as it seems.Take shipping for example, which has to go two ways if an item is rented – receiving and returning. Cline writes that consumer transportation has the second largest carbon footprint of our collective fashion habit after manufacturing.Then there’s the burden of washing, which has to happen for every item when it’s returned, regardless of whether or not it was worn. For most renting services, this usually means dry-cleaning, which is a polluting process. All the renting services that Cline looked into have replaced perchloroethylene, a carcinogenic (致癌的) air pollutants that’s still used by 70 percent of US dry cleaners, with hydrocarbon (碳氢化合物) alternatives, although these aren’t great either. They can produce harmful waste and air pollution if not handled correctly.Lastly, Cline fears that renting services will increase our appetite for fast fashion, simply because it’s so easily accessible. There’s something called “share-washing” that makes people have more wasteful behaviors because a product or service is shared and thus is considered more eco-friendly. Uber is one example of this: advertised as a way to share rides and reduce car ownership, and yet it has been proven to discourage walking, bicycling and public transportation use.Renting clothes is still preferable to buying them cheap and throwing them into the bin after wearing them a few times, but we shouldn’t let the availability of these services make us self-satisfied. There’s an even better step – and that’s wearing what we already have.12. What do we know about Elizabeth Cline from the passage?A. She is trying to attract shoppers.B. She is an expert and journalist.C. She has created “share-washing”.D. She never rents clothes.13. Why does renting services increase people’s appetite for fast fashion?A. Because it is handled correctly.B. Because it is transported easily.C. Because it is fairly eco-friendly.D. Because it is easily accessible.14. What can we infer from the passage?A. Clothing renting became popular ten years ago.B. Consumer transportation has the largest carbon footprint.C. Renting clothes deserves further consideration.D. Uber is a good example of sharing rides.15. Which section of a newspaper does the text probably come from?A. Environment.B. Technology.C. Travel.D. Medicine.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

Criticism from coaches, parents and other teammates, as well as pressure to win can create too much anxiety or stress for young athletes. Stress canbe physical, emotional, or psychological and research has indicated that it can lead to burnout. Burnout has been described as dropping or quitting of an activity that was at one time enjoyable.The early years of development are critical years for learning about oneself. The sport setting is one where valuable experiences can take place. Young athletes can, for example, learn how to cooperate with others, make friends, and gain other social skills that will be used throughout their lives. Coaches and parents should be aware, at all times, that their feedback to youngsters can greatly affect their children. Youngsters may take their parents and coaches’ criticisms to heart and find faults in themselves.Coaches and parents should also pay attention that youth sport participation does not become work for children. The outcome of the game should not be more important than the process of learning the sport and other life lessons. In today’s youth sport setting young athletes may be worrying more about who will win instead of enjoying themselves and the sport. Following a game many parents and coaches focus on the outcome and find faults with youngsters’ performances. Positive support should be provided regardless of the outcome. Research indicates that positive support motivates and has a greater effect on learning than criticism. Again, criticism can create high levels of stress, which can lead to burnout.4. An effective way to prevent the burnout of young athletes is_____________.A. to make sport less competitiveB. to increase their sense of successC. to reduce their mental stressD. to make sport more challenging5. According to the passage, sport is positive for young people in that_____________.A. it can help them learn more about societyB. it enables them to find faults in themselvesC. it can provide them with valuable experiencesD. it teaches them how to set realistic goals for themselves6. Many coaches and parents are in the habit of criticizing young athletes_____________.A. believing that criticism does good to their early developmentB. without realizing criticism may destroy their selfconfidenceC. in order to make them remember life’s lessonsD. so as to put more pressure on them7. According to the passage parents and coaches should_____________.A. pay more attention to letting children enjoy sportB. help children to win every gameC. train children to cope with stressD. enable children to understand the positive aspect of sportCFor as long as I can remember, my body and I have shared a relationship of discontent. Growing up, I was skinnier than the other kids and at five I was told I wasn't attractive and that I must put on some weight. But no matter how much I ate, I stayed thin for years until adolescence. Then I started putting on weight almost immediately. I remember feeling happy as I began to fill out. However, my joy didn't last long.I was thirteen when I was first called fat. Friends and neighbours would make jokes on my big size. As I entered my late teens, I had completely lost confidence in my body and, subsequently, in myself. Having failed to live up to conventional beauty standards, I was convinced that if I wanted to be loved, I needed to offer more, doing anything to please everyone around.I entered adulthood thinking I wasn't “enough”—an idea that was seeded not only by the fact that “skinny” is celebrated, but also by the language associated with accounts of losing weight—selfimprovement, discipline—all virtues. Being fat quickly categorizes you as lazy and undisciplined. Consumed by thoughts of the way my body looked, I didn't notice the other ways my body needed attention. I failed to realize, for example, that my period was much heavier and more painful than ever before. Actually I developed a rare disease and later I had two surgeries.I was always made to feel that my weight was the root of a lot of problems in my life; I have learnt this is not true. After a lot of selfreflection and some professional help, I realized I never learnt to like myself. While two decades of selfhatred cannot be undone overnight, I have taken first steps to acceptance.I am now much lighter than before, in body and mind. There are days I find voices on social media saying I am too fat to be loved or to be worthy, but I am learning not to focus on that thought for long. As long as I like myself,just the way I am, opinions at the end of the day are just water off a duck's back.8. What can we learn about the author from the first two paragraphs?A. She could change her weight at will.B. She had different beauty standards from others.C. She tried to love others to build her confidence.D. She was greatly influenced by others' opinions.9. Why did the author think she wasn't “enough”?A. She was poorly disciplined.B. She failed to celebrate “skinny”．C. She was labelled as lazy for her weight.D. She put on more weight after entering adulthood.10. What caused the author to make a change?A. Her lighter body.B. A troublesome illness.C. Popular beauty standards.D. Others' critical comments.11. What is the best title for the text?A. Beauty matters.B. Opinions vary.C. Worth your weight.D. Beyond your limits.DPaper is one of our oldest, simplest and most important inventions. But it also presents a danger to the world in two important ways. First, the making of paper requires the loss of many millions of trees each year. And worldwide use of paper is expected to double in the next 40 years. Clearly, the planet cannot stand such a high rate of forest loss. The second great problem with paper is what happens once it is no longer useful. A large amount of wastepaper ends up in landfills, where it can produce harmful gases and finally contribute to global climate change.One simple solution can greatly reduce both of these problems: paper recycling. Instead of cutting down trees, recycle existing paper to feed the paper-making process.Paper is mainly made from cellulose (纤维素)，which can be used repeatedly in papermaking. Unfortunately, it also means that paper waste takes a surprisingly long time to break down in landfills. So far, trees are the only source(来源) of cellulose that can fill the great demand for paper products. Therefore, recycling paper is simply one of the best ways to save trees. Thanks to advances in processing, recycled paper need not be the dark-color1edstuff many of us are familiar with. It now can offer the same print performance as non-recycled paper.Effective recycling requires a continuous effort from everyone at all levels of society. The way to begin is with education and understanding. Once enough people realize the need for recycling, more effective recycling systems can be developed.The need is real. The massive loss of trees affects everybody on earth. Everyone should do their part to recycle paper and encourage government and industry to do the same. The world will be a better place for it!12. What can we infer from the text?A. The use of recycled paper will double in 40 years.B. Recycling paper helps relieve global climate change.C. Wastepaper can easily break down in landfills.D. There are not enough landfills for wastepaper.13. What makes recycled paper more acceptable?A. The great demand of trees.B. The low processing cost.C. Its dark-color1 ed feature.D. Its improved print performance.14. What does the author propose?A. Punishing the act of cutting trees.B. Recycling paper.C. Improving recycling system.D. Promoting paper industry.15. How is the text mainly developed?A. By analyzing causes and effects.B. By offering research plans and data.C. By discussing problems and solutions.D. By comparing strengths and weaknesses.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

Here are several places to hit the open road.Colo-road TripsThe Colorado Tourism Office has made it easy for road-trippers to explore the state’s 24 Scenic & Historic Byways.A new microsite includes-an interactive map that enables travelers to explore options by region, interest or season. Travelers seeking inspiration can also access insider tips and side-trip suggestions for historic attractions, active adventures and highlight cultural opportunities.TheBeartooth Highway.Visitors of this extraordinary byway experience the grand sights ofMontana,WyomingandYellowstonePark. The windy 68-mile stretch introduces road explorers to one of the most diverse ecosystems accessible by auto. Breathtakingly beautiful, this All-American Road showcases wide, high alpine plateaus（高原）, painted with ice blue lakes, forested valleys, waterfalls and wildlife.SewardHighway,AlaskaThe road that connectsAnchorageto Seward is 127-mile treasure of natural beauty, wildlife and stories of adventure. The drive begins at the base of theChugach Mountains, hugs the scenic shores of Turnagain Arm and winds through gold mining towns, national forests and fishing villages. Expect waterfalls, glaciers, eagles and some good bear stories.The Lighthouse Trail,MaineTravel the 375 miles betweenKitteryandCalais,Maine, visiting lighthouses along the way. Hear tales of shipwrecks（海难）and of the difficult and lonely life led by those who kept the lights burning brightly. If possible, visit theMaineLighthouseMuseum. where artifacts and hands-on exhibits for children provide an appealing break.1.What makes Colo-road Tips special?A.Good bear stories.B.A scenic beach.C.Hands-on exhibits.D.An interactive map.2.Where can you explore state of gold miners?A.Colorado.B.Montana.C.Alaska.D.Maine3.Which place is suitable for a family with children?A.Colo-road Trips.B.TheBeartooth Highway.C.Seward Highway.D.The Lighthouse Trail.BSome of the oldest art in human history is being damaged, scientists say. And climate change may be speeding up its loss. Newresearch reports that ancient rock art in Indonesian caves is degrading over time, as bits of rock slowly break off from the walls. It's a huge loss for human history.Salt crystals（结晶）building up on the walls are a key part of the problem, the study suggests. These salt crystals go into the cave walls, changing sizes as temperatures rise and fall. This process causes the rock to slowly break down.Salt crystals may become larger when exposed to repeated changes between wet conditions and periods of drought. These kinds of changes are expected to become more obvious as the climate continues to warm.In particular, the researchers say, climate change may cause more intense El Nino（厄尔尼诺）events in the future. These events can strengthen the kinds of conditions that help salt crystals form Scientists are still debating the exact influence of climate change on El Nino, a natural climate cycle that drives changing patterns of warming and cooling in thePacific Ocean.The new study, led by Jillian Huntley, examined 11 ancient cave art sites in South Sulawesi, Indonesia. The researchers found evidence of salt formation at all 11 sites. It's merely a small part There are more than 300 known eave art sites around the region. The researchers note that salt crystals may indeed be part of the problem, adding that climate change is a growing threat, one that deserves more attention.4. What is the main cause of the rocks breaking off from the wall?A. Weather patterns.B. Salt crystals.C. Wet conditions.D. Drought Periods.5. Which of the following may researchers agree with?A. El Nino events prevent salt crystals forming.B. Climate change makes little difference to El Nino.C.Salt crystals may become much larger in wet conditions.D. Constant warm weather may cause salt crystals to change size.6. Which word best describes Huntley's attitude to climate change?A. Worried.B. Curious.C. Doubtful.D. Positive.7. What can we learn from thelast paragraph?A. The formation and patterns of salt crystals.B. The impact of climate change on ancient rock arts.C. The historical value of ancient rock art in cave sites.D. The threats of human activities to ancient eave art sites.CThe annual 3-to-4-millimeter rise in sea levels is expected to impact many coastal communities in the coming decades. However, few are as defenceless as the Republic of theMaldives, a collection of more than a thousand picturesque islands in theIndian Ocean. NASA researchers believe that parts of what is “arguably the lowest-lying country in the world” will become uninhabitable by 2050, due to wave-driven flooding and limited freshwater. To fight the unavoidable, the government recently revealed plans for the world's first 'true' floating island city.The aptly-named Maldives Floating City (MFC) is the brainchild of Dutch Docklands, a global leader in floating infrastructure (基建). According to the March 13, 2021, announcement, the new city will be constructed on a 200-hectare lagoon (环礁湖) located just 10 minutes by boat from the Maldivian capital, Male. It will initially consist of a thousand waterfront residences, arranged in a series of honeycomb-like maze rows. The developers plan to add hotels, restaurants, shops, and even a school and a hospital in the near future. The floating structures. will be attached to the surrounding islands, which will form a base and provide protection from high tides.Maldive officials aim to make MFC as self-sufficient as possible. Freshwater storage will provide drinking water for residents, while floating solar blankets and agriculture fields will take care of their energy and food needs.“ThisMaldivesFloatingCitydoes not require any land rehabilitation, therefore has a minimal impact on the coral reefs,” explains Mohamed Nasheed, Speaker of Parliament. “What's more, giant, new reefs will be grown to act as water breakers. In theMaldives,we cannot stop the waves, but we can rise with them.”Construction of the revolutionary city is expected to begin in 2022 and be completed in phases over the next five years. If successful, it will provide a blueprint for other countries facing a similar situation.8. Why doesMaldivesdecide to build MFC?A. It is the lowest-lying country.B. It will be flooded soon.C. It is running out of fresh water.D. It will be unsuitable for living.9. What is Paragraph 2 mainly about?A. The prospect of MFC.B. The developers of the plan.C. The location of the residences.D. The barriers to the construction.10. What can we infer from the underlined words?A. MFC will keep waves away.B. MFC will make use of waves.C. MFC will adjust to the waves.D. MFC will work as water breakers.11. What's the writing purpose of this passage?A. To introduce a construction program.B. To appeal to people to protect nature.C. To seek international help forMaldives.D. To report the achievement of a city plan,DHave you ever done something for someone else—knowing that your actions would solely benefit THEM and not YOU? Maybe you opened a door or donated blood or volunteered in a hospital’s ER during the pandemic. This is called a prosocial behavior. Humans engage in these types of behaviors all the time.But a question remains in science: Are we the only species who do this? As one of out closest s, chimpanzees have long been studied for signs of this. So far, research has provided mixed results on the question.Some studies show that chimps cooperatively hunt, share food and comfort each other. But one study came to a very different conclusion. The study used a controlled lab experiment where chimpanzees in enclosures were given two options: push a button to give food to themselves or push the button to give food to themselves AND a partner chimp. If they chose the latter, it was seen as a prosocial behavior. But the result is that chimps showed no special preferences for feeding themselves and a friend over feeding just themselves. Another study conducted by DeTroy, however, discovered a totally different result.Compared to previous controlled lab-based experiments, the setup for DeTroy’s research was very naturalistic. “We installed a button and a fountain into the chimpanzees’ outer enclosures. When an individual pushes the button, it releases juice from the fountain. However, since the button and fountain are approximately five meters apart, the individual pushing cannot directly drink from the fountain. And if any other chimpanzees are at thefountain when the button is pushed, they, and not the pusher, will be able to drink the juice.In this experiment, chimpanzees showed a willingness to act in the interest of others, with individual chimpanzees prepared to push the button without benefiting themselves.“It is really fascinating to see that many of the chimpanzees were willing to prosocially provide valuable resources to the group members even if they couldn’t benefit themselves from their behavior.” said DeTroy.Further research may reveal what lies behind their prosocial motivation. But for now, it’s safe to assume that chimpanzees are not simply aping human behavior.12. Which of the following belongs to prosocial behaviors?A. Jack participated in voluntary work in the library just to earn credits.B. Mark turned to his classmate for help when feeling stressful in study.C. Tim guided a lost child back home on his way to an important job interview.D. Rose often interrupted the teacher to ask questions actively in the math’s class.13. What is the task of the chimpanzees in the lab-based study?A. Sharing food.B. Making a choice.C. Comforting others.D. Showing sympathy.14. How is DeTroy’s study different from the previous ones?A. It was based on controlled lab experiment.B. It gave juice to the chimpanzees as a reward.C. It offered the tested chimpanzees a natural surrounding.D. It provided a chance for chimpanzees to help their partners.15. What can we learn from DeTroy’s quotes?A. Chimpanzees can develop abilities to help others.B. Chimpanzees have acquired many human behaviors.C. Chimpanzees in the wild is cleverer than those in the lab.D. Chimpanzees displayed prosocial behaviors for certain rewards.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

What do Italy and Czech Republic havein common?A. Astronomy.B. Architecture.C. Paintings.D. Medicine .BThe Rise of Voice TechnologyVoice technology has come a long way. Just a few years ago, it would have been unusable. But now, those who follow the technology know that it has got considerably better.Writing with your voice raises several interesting questions. How difficult is it actually? Human speech involves a lot more starting and stopping with errors and the need for repairing broken sentences than you may think. Even gifted speakers make mistakes. To turn the spoken word into reasonable writing requires lots of planning. You’ll need some kinds of notes or other organisers to make it work.Another question turning speech into writing raises is the style. How would writing make the change that people speak their writing rather than type? Chances are that it would come up with many more short sentences and more concrete language, which is good. It would probably also rely on prepared phrases a lot more often, which is not available when you are speaking quickly.To confirm this, a column was not written, but dictated (听写). It was composed from brief notes written down for structure only, and it was edited for length, with all of the original errors kept in. Here were the results. The first was that the literal accuracy was extremely high. There weren’t many cases wherethe software had heard one word incorrectly and written down another. But the other result was that the readability of this column was rather bad. Obviously, the blame is not with the technology at all, which turns out to be rather good. Speaking into writing relies on a better human brain than the one we currently possess. Writing is hard. There’s a reason it can’t be done at the speed of speech, in real time.To clarify the matter, this time paragraph breaks were added after the whole writing. Punctuations (标点) had to be spoken aloud, and after a full stop, the first word in the new sentence was capitalized automatically. Some minor punctuation marks were added to make it clearer. To improve accuracy, people “trained” the softwarebeforehand, reading a prewritten passage aloud. Actually it turns out to be more effective. All of these ensure the satisfactory completion of turning speech into writing.Language is the most important tool for human interaction, and voice is one beautiful part of language. With the maturity of modern technology, it has given birth to a great change in the human-computer voice interaction.4. According to the passage, which helps to turn speech into writing in terms of style?A. There is careful planning in advance.B. Errors and broken sentences are avoided.C. People type words as fast as they say them.D. The writing contains more prepared phrases.5. To achieve better results, the author mentions some changes for ______.A. processing errors in a column.B. adding minor punctuation marks.C. increasing the number of brief notes.D. integrating short paragraphs in writing.6. The author suggests that ______.A. human brains are responsible for poor dictated writing.B. writing with voice promises to improve the quality of writing.C. writing is an unnatural act that can hardly be learned and improved.D. technology has a long way to go in the human-computer voice interaction.7. What is the passage mainly about?A. Why people fully intend to turn speech into writing.B. What role voice technology plays in improving readability.C. Where the human-computer voice interaction is at an advantage.D. How voice technology enables the change from speech into writing.CTwo young brothers fromMalden.Massachusettswere in the spotlight Thursday after being named “heroes" by a national organization that recognizes young people doing great things. For the Bennett brothers, the goal of their work is nothing less than helping researchers find a cure for cancer. And their inspiration came from a friend.Thirteen-year-old Hany Bennett and his nine-year-old brother Heath run their business out of their family kitchen. "We're making lip balm（润唇膏），"Harry says. They got the idea two years ago when their friend, Timmy,was diagnosed（诊断）with cancer. brothers wanted to do something. We learned that cancer patients（lips and skin can get really dry because of chemotherapy（化疗），Hany says.A light bulb went off in both of their young heads,and " Bennett Brothers Balm was born. "We make lip balm, which is kind of like our main product/ says Heath. They also make and sell different body balms, all natural, all handmade, while the profits benefit cancer research. "We've raised S 15,000/ Heath says.And with the great optimism of children, they don't just want to help；they wont to win. We want to find a cure. We want to help doctors find a cure, Harry explains, The brothers are also Gelding a team for the Light the Night Walk, to fight cancer."I think it's great to raise money and help people who have cancer," says Heath. Their parents play a big role as well, but it's the boys who provide the most enthusiasm with a message we can all learn from. "If you want to do something... do it," Harry says. "I just feel very glad that we're helping. It feels very good”，adds Heath.Harn and Heath just received the S 10,000 Gloria Barron Prize for Young Heroes.

The longest journey begins with the first step.DTourism is often about seeking deeper emotional and personal connections with the world around us. Not all travel experiences, however, need to take place in the real world. With the evolution of virtual reality(VR) technology, tourism will increasingly become a combination of physical and virtual worlds. VR may even remove the need to travel entirely.But can a VR experience really equal a real world one? Many experts believe it can. Studies have shown that our brains have an inbuilt VR-like mechanism that enables us to live imagined experiences. Much of our waking life is spent thinking about either the past or the future. This is known as" mind wandering". During these events we' re not paying attention to the current world around us. Instead, we' re recalling memories, or creating and processing imagined futures.When engaged in mind wandering, our brains process these mental images using the same pathways used to receive inputs from the real world. So, the imagined past or future can create emotions and feelings similar to how we react to everyday life. VR can create these same feelings.While critics might argue that a virtual experience will never match reality, there are several ways VR tourism could make a positive contribution. Firstly it could help protect sensitive locations from over-tourism. In recent years famous sites such as Maya Bay in Thailand, and Cambodia's Angkor Wat Temples have had to limit the number of visitors because of their negative impact. These places are now producing their own VR experiences that will allow tourists to pass through virtual models of the sites.Virtual reality may also allow people back in time, to experience historical events, visit ancient cities, and even to walk among dinosaurs.Finally, in a world where many people suffer from stress and depression due to overwork, virtual tourism may provide a cheap and convenient way for people to take brief holidays to otherwise unreachable destinations and recharge their batteries, without ever leaving their homes.It sounds like science fiction but it's already happening. As virtual technology improves and as people continue to demand new and interesting experiences, expect more virtual tourism, both in combination with the real world and instead of it.12. What is driving the development of virtual tourism?A. Companies seeking to make more money.B. Improvements in virtual reality technology.C. People's demand for more shared experiences.D. People's deeper understanding of the physical world.13. Which of the following best describes "mind wandering"?A. The brain processes which help people think VR is real.B. The way the brain processes inputs from the real world.C. Brain activities focusing on past or future events.D. Experiences coming from a person's imagination.14. What does the underlined word "it" in the last paragraph refer to?A. Science fiction.B. Virtual technology.C. Virtual tourism.D. The real world.15. What is the purpose of the passage?A. To describe the advantages of VR tourism.B. To give suggestions for reducing over-tourism.C. To encourage people to develop VR technology.D. To argue VR tourism will replace the real world travel.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。
