I wanted to play outside and not to be made to finish eating my old rice. When angrily opening the screen door (纱门) with my foot, I kicked back about a 12-inch part of the lower left hand corner of the new screen door. But I had no regret, for I was happy to be playing in the backyard with my toys.Today, I know if my child had done what I did, I would have blamed my child, and told him about how expensive this new screen door was, and I would have delivered a spanking (打屁股) for it. However, my parents never said a word. They left the corner of the screen door pushed out, creating an opening, in the defense against unwanted insects.For years, every time I saw that corner of the screen, it would constantly make me think about my mistake. For years, I knew that everyone in my family would see that hole and remember who did it. For years, every time I saw a fly buzzing (嗡嗡) in the kitchen, I would wonder if it came in through the hole that I had created with my angry foot. Iwould wonder if my family members were thinking the same thing, silently blaming me every time a flying insect entered our home, making life more terrible for us all. My parents taught me a valuable lesson, one that a spanking or stern (严厉的) words perhapscould not deliver. Their silent punishment for what I had done delivered a hundred stern messages to me. Above all, it has helped me become a more patient person and not burst out so easily.1. When the author damaged the door, his parents _______.A. gave him a spankingB. left the door unrepairedC. told him how expensive it wasD. blamed him for what he had done2. The experience may cause the author _______.A. not to go against his parents’ willB. to have a better control of himselfC. not to make mistakes in the futureD. to hide his anger away from others3. What is the main idea of this text?A. Parents is the best way to solve problems.B. Parents are the best teachers of their children.C. Adults should ignore their children’s bad behavior.D. Silent punishment may have a better effect on educating people.BThe 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.CAlthough computer technology is often necessary today, using a pen or pencil activates more areas of your brain than a keyboard does. You can potentially remember more by handwriting, according to a new study.The potential benefits of handwriting for memory have been debated for some time. The new study set out to answer one question: How does handwriting compare to using a keyboard when it comes to remembering new information?In all,24 participants took part. Researchers asked each of them to write with a pen and then each was also asked to type on a keyboard. While performing these tasks, each volunteer wore a cap that held electrodes next to their head. It looked somewhat like a hair net fitted with 256 sensors. Those sensors recorded the participants' brainwaves. The electrodes noted which parts of the brain turned on during each task. And they showed that writing turned on memory areas in the brain while typing didn't.Audrey van der Meer, the new study's leader, says this suggests that when we write by hand, we remember better. “This is because writing involves complex movements that activate more areas of the brain. The increased brain activity gives the brain more ‘hooks’ to hang your memories on,” she explains. Van der Meer also points out that writing by hand is related to visual notetaking. “Rather than typing blindly, the visual notetaker has to think about what is important to write down. Then, key words can be interlinked by boxes, arrows and small drawings,” she adds.This study does not recommend banning digital devices. In fact, its authors point out, computers and other devices with keyboards have become necessary in modern society. Keyboarding can especially benefit those with certain special needs (such as if they have trouble using their hands) and typing beats writing when it comes to speed, they add.8. Why were participants asked to wear caps in the study?A. To record their brainwavesB. To inform them of their tasksC. To allow them to focus on writingD. To protect their heads like hair nets9. What does Audrey van der Meer try to explain?A. Why handwriting is more complex than typingB. Why the brain works when it comes to learningC. Why handwriting helps remember informationD. Why key words are helpful to visual notetaking10. What is the study's authors' view on typing?A. It relieves people's handsB. It remains vital and helpfulC. It is not worth recommendingD. It is more challenging than writing11. Which of the following can be a suitable title for the text?A. How Can You Remember New Information?B. Handwriting Benefits Health in the LongRunC. Should Typing Take the Place of Handwriting?D. Handwriting Is Better for Memory Than TypingDWhen rescuers were called to rescue a “little owl”, they did not expect to find one that was too fat to fly. A concerned citizen first spotted the poor bird lying helplessly. Even Rufus Samkin, whose team then took the team in on Jan.3, believed the bird to be injured. There were no wounds to be found, however, causing experts to believe the female owl was simply too wet to fly.But it was only after a thorough drying-off and complete checkup that they noted the real issue. The rescuers weighed the owl and concluded that she was “simply extremely obese” and couldn’t take off. This additional weight left her unable to fly, though experts began to wonder how she got so fat in the first place. Because it’s rather unusual for wild birds to reach such a state, they decided to keep her a few weeks and monitor her.In the end, the rescuers assessed that it was simply a case of “natural obesity”. December 2019 was quite warm, which meant that there were many insects for the bird to feast upon. Indeed, the owl was discovered in a field that was “filled with field mice” due to the usual climate. “It’s been very mild here, and the owl is able to find foods easily,” Samkin explained. With the sudden food, “she ly ate much and got very fat. She had a lovely time, but went too far.”The researchers consequently put the owl on a “strict diet” so she could shrink to a more “natural weight”. She was even put on a bit of exercise and encouraged to fly around. In the end, the bird was sent flying gracefullyoff into the British countryside at a much healthier and happier weight. Hopefully, this owl won’t come upon another feast of field mice—unless she wants another few weeks at the fat camp.12. What did people think happened to the owl at first?A. She was hurt.B. She was trapped.C. She was hungry.D. She was wet.13. Why was the bird unable to fly?A. She needed a thorough checkup.B. She should be given a drying-off.C. She was completed overweight.D. She was simply extremely strong.14. What made the owl have enough foods?A. The especially warm weather.B. The reducing number of insects.C. The rich fields growing crops.D. The lovely time the bird enjoyed.15. How did the owl loseits weight?A. Going on a diet and exercising.B. Flying in the British countryside.C. Visiting that fat camp again.D. Enjoying her wonderful feast freely.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。

Elion spent her early youth in Manhattan. She attended senior high school and had, in her words, an unbelievable thirst for knowledge.Influenced by the death of her grandfather, who died of cancer, Elion entered Hunter College at the age of 15 and graduated in chemistry at the age of 19. She had difficulty finding employment after graduation because many laboratories refused to hire women chemists. She found a part-time job as a lab assistant and went back to school at New York University. Elion worked as a high school teacher for a few years after finishing work on her master’s degree.The start of World War II created more opportunities for women. At the age of 26, Elion was able to get a job at Burroughs Welcome, where she began a 40-year partnership with Dr. George H. Hitchings. Her thirst for knowledge impressed Dr. Hitchings, and he permitted her to take on more responsibility.Elion and Hitchings set out on a course of creating medicines by studying the chemical composition of diseased cells. Rather than relying on old trial-and-error methods, they used the differences in biochemistry between normal human cells and pathogens(病原体)to design medicines. In all, Elion obtained 45 patents on medicine and was awarded 23 honorary degrees.In 1988, Elion received the Nobel Prize for Medicine, together with George H. Hlitchings and Sir James Black. She received other awards for her work, including the National Medal of Science in 1991, and that same year, she became the first woman to beabsorbed into the National Inventors Hall of Fame.

A report published this week suggests that climate change has a negative effect on our mental health, too.The study, published in the journal Proceedings of the National Academy of Sciences of the United States(PNAS), links an increase in monthly temperatures to a rise in mental health issues. The experimental evidence stems from meteorological (气象的) data paired with information collected from nearly 2 million randomly sampled residents in the United States. The data was collected over the span (跨度) of a decade.“We find that experiences with hotter temperatures and added rainfall each worsen mental health, that long-lasting warming associates with an increased popularity of mental health issues, and that exposure to tropical cyclones(热带气旋), likely to increase in frequency in the future, is linked to worsened mental health,” authors of the study stated. “These results provide added large-scale evidence to the growing link between climate change and mental health.”The report specifically focused on mental health outcomes due to the effects of environmental stress - such as temperature, rainfall, and tropical cyclones - but other climate change-related issues are likely to affect mental health as well - specifically, the stress and anxiety of knowing natural disasters could be more frequent as temperatures rise.8．From the newly-published report, we learn that the climate change may _________.A．save a lot of people’s livesB．cause unbelievable disastersC．influence people’s mental healthD．greatly change people’s life styles9．Why did the author mention “the span of a decade” in Paragraph 2?A．To stress the importance of the study.B．To show that the study cost too much money.C．To explain the difficulties and hardships of the study.D．to indicate that the study is objective and believable.10．Where can we find some specific results of the study?A．In Paragraph 1B．In Paragraph 2C．In Paragraph 3D．In Paragraph 411．What can we infer from the last paragraph?A．The study has its limits.B．The results of the study aren’t satisfactory.C．The environmental problems can’t be solved.D．Mental health is determined by climate change.Your child is unique, but what all children have in common is natural curiosity(好奇心)and an ability to learn they are born with. Our brains are active all the time, and a baby’s brain is the busiest of all. Research has shown that babies begin to understand language about twice as fast as they actually speak it. By showing children other languages at an early age, you are giving them the opportunity to make use of their natural ability to hear and recognize (辨认)between the sounds of other languages, and their ability to make sense of what they are hearing.Communication is something that children do to help them achieve something else, and they are unaware of the large amount of learning taking place. They take everything inthrough their senses, making connection between what they hear, see, smell, taste and touch. As long as we provide the right conditions, their learning and development will take place in a natural way.In your child’s early years, the emotional environment is just as important as the physical environment. Children learn when they feel safe, happy, valued and listened to. This is central to any learning experience in child’s early years, including learning an additional language. Your child has a trial (试验)-and-error approach to its development, and making mistakes is a valuable part of the learning process. When children learn an additional language at an early age, they get the benefits of experimenting with that language as a natural part of their development. Their progress isn’t prevented by a fear of getting it wrong, a nd very young children are simply working their way towards getting it right.The long-term benefits of learning another language go beyond being able to communicate with others. Studies suggest that children learning an additional language tend to score better on standardized tests because learning languages develops listening, observation, problem-solving and critical (批判性的)thinking skills. These are skills that are of life-long benefit, both personally and professionally. Encouraging in children a love of language at an early age prepares them well for school and for life.12．what do we know about Children according to Paragraph 1?A．Children are busy playing.B．Children are born to speak.C．Children are good at speaking native language.D．Children live a better ability to learn other languages.13．While learning a language, children ________ .A．spook to themselves B．need to have language classesC．make use of their different senses D．notice how much they have learned 14．Children learn when they________.A．are in bad emotion B．need to have language classesC．learn from their mistakes D．are taught by their teachers15．In fact learning another language helps children to________.A．take more tests B．have a good timeC．encourage themselves D．develop life-long skills二、七选五Small Talk Might Get You Big RewardsIn many culture, small talk is a big deal. Although it may seem like a pointless conversation to pass the time or avoid awkward silence, it is actually very important for communicating and bonding with others.According to US inspirational speaker Melissa Wadsworth, “Small talk is about tapping into possibility.” Having good small talk skills is the best way to meet new people, which can lead to friendships, jobs, or other goals. 16If small talk is so important, how do you do it? What’s the best way to break the ice and start talking to people? Well, some of the most common topics include the weather, hobbies, work, family and travel. 17 It’s easy for people to talk about them.18 For example, you can talk to your schoolmates about your classes or that teacher who drives everyone crazy. 19 If you’re lucky, you might have a friend introducing you to others firstly to help you start a conversation.Sometimes, it may seem a bit difficult to start a conversation with someone you don’t know. That’s OK! 20 Wadsworth has the best advice for this: “approach the conversation excited about the friendship, the good laugh, the fascinating story, the job opportunity, the date, the joy or the sense-of-belonging potential inherent (内在的) in this shared experience.”Small talk might just be the first step to something much bigger.A．Everyone has this problem sometimes.B．Another way to start small talk is to comment on your surroundings.C．These topics are great for small talk because they are valuable.D．Small talk can also be used for striking up a conversation.E．Not only that, small talk is shown to boost brainpower by encouraging empathy, making you consider what another person feels or thinks.F．Nobody would doubt the values of small talk.G．If you’re at a party, you might comment on the snacks, music, or the number of people there of video games.三、完形填空阅读下面短文，掌握其大意，然后从16－35各题所给的A．B．C．D四个选项中，选出最佳选项。

Some rich mothers and fathers now are more like snowplows: machines moving ahead, clearing any difficulties in their children’s path to success, so they don’t have to suffer failure, frustration (挫折) or lose opportunities.It starts early, when parents get on wait lists for excellent preschools before their babies are born and try to make sure their kids never do anything that may frustrate them. It gets more intense when school starts: running forgotten homework to school or calling a coach to request that their children make the team.Rich parents may have more time and money to devote to making sure their children don’t ever meet with failure, but it’s not only rich parents practicing snowplow parenting. This intensive parenting has become the most welcome way to raise children, regardless of income, education, or race.Yes, it’s a parent’s job to support the children, and to use their adult wisdom to prepare for the future when their children aren’t mature enough to do so. That’s why parents hide certain toys from babies to avoid getting angry or take away a teenager’s car keys until he finishes his college applications.But snowplow parents can take it too far, some experts say. If children have never faced a difficulty, what happens when they get into the real world?“Solving problems, taking risks and overcoming frustration are key life skills,” many child development experts say, “and if parents don’t let their children experience failure, the children don’t acquire them.”4. What do we know about snowplow parenting?A. It appeared before helicopter parenting.B. It costs parents less than helicopter parenting.C. It was a typical phenomenon of the 20th century.D. It provides more than enough services for children.5. What is mainly discussed about snowplow parenting in Paragraph 4?A. Its cost.B. Its benefits.C. Its popularity.D. Its ending.6. Why does the author mention parents’ taking away car keys?A. To show teenagers are no better than babies.B. To advise teenagers not to treat their cars as toys.C. To advise parents not to buy cars for their teenagers.D. To show it’s appropriate to help children when necessary.7. What’s the possible result of snowplow parenting according to the experts?A. Children lacking problem-solving ability in reality.B. Children mastering more key life skills than parents.C. Children gaining great success in every aspect of life.D. Children meeting no problems or frustration after growing up.CI got my first bike when I was nine years old. Jimmy, the bike, was my first love. I rode it everywhere. The suburb, the back lanes, the fields and forests, the river paths and swampland were far more exciting than any adventure novel or television series.There’s nothing quite like the relationship between a child and his bicycle and the endless happiness two wheels and a pair of strong legs offer. No video or computer game can replace the liberation of being alone on a bicycle.As parents, to deny children the simple pleasure of riding a bike is a failure of our responsibilities to raise independent and stable young citizens. We should offer our children a healthy alternative to hours in front of an addictive screen. Studies have shown that cycling promotes not only muscle growth but brain growth. Guess which country has children with the best mental health outcomes and is regularly the top of listings of the happiest young people. No surprise it’s theNetherlands, the unquestioned leader among industrial countries in encouraging bicycle use.Our dependence on cars has degraded the public transport system, polluted our sky, led to the untimely death of thousands every year, and denied children safe access to their suburbs. A recent study found that 69% of children were accompanied to school. The same study found that a similar number of parents drove to work.In some regions ofJapan, when children start their first year of school, parents are expected to walk with them for the first few weeks, introducing them to residents and shopkeepers along the chosen route, letting thecommunity take care of these children. However, driving children to school isproscribed. Children can choose to ride a bike or walk to school after they are familiar with the community, and it’s the community’s role to keep them safe.Therefore, I strongly advise the government to provide better infrastructure (基础设施). Build separated cycle lanes, decrease speed limits, and design street scapes that favour people over cars. The results will be less pollution, quieter suburbs, a healthier population and, best of all, happy and independent children.8. What can we infer about the author from the text?A. He was addicted to computer games.B. He liked taking adventurous trips in nature.C. He had great fun exploring the outside by cycling.D.He got his first birthday present at the age of nine.9. Why does the author mention theNetherlandsin Paragraph 3?A. To introduce his good way of raising independent children.B. To illustrate the great influence riding has on mental health.C. To stress the importance of being physically and mentally healthy.D. To explain cycling does best in city development in theNetherlands.10. What does the underlined word “proscribed” in Paragraph 5 probably mean?A. Recommended.B. Protected.C. Delayed.D. Forbidden.11. How does the author mainly support his idea?A. By analyzing causes.B. By listing examples.C.By giving definitions.D. By analyzing scientific data.D"Sorry, but I don't agree with you..."This is usually followed by unbearable silence and angry tears. I've always found it difficult to disagree with someone, because I don't want to lose a friend. I've found it even harder to accept it when someone disagrees with me, because my ego（自尊心）ishurt.Before the other person gets a chance to explain why she disagrees with me, my usual response would be," If you aren't able to see my point of view, then what you think isn't worth my time or consideration, either." But now I've come to realize that when a friend disagrees with me, sometimes she is simply saying, "I don't agree with the way things are done." She still respects me as a person, and is only pointing out a better way to look at a matter. However, there may be times when my friend disagrees with me because I'm against the truth. That's when needto listen to what she says.I've learned that one way to help my friend is for me to be open and honest with the other to voice my thoughts and listen to the other carefully. While we can't control how a person will respond to our views, we must learn to disagree with our friends in love. We will never feel that we are better than the other person.And that will help us to be less emotional, and more objective in the way we express our opinions.In the same way, we can also stay open to feedback（反馈）from others,knowing that our friends may be correcting us in love.Good friendships build each other up, sometimes through disagreements and honest opinions. Though I don't like being disagreed with, I'm starting to see the value of such disagreements.12. The author has found it difficult to disagree with someone because .A. he is a friendly personB. he usually hides his ideasC. he has no mind of his ownD. he wants to keep the friendship13. When a friend disagreed with him,the author used to .A. be unhappyB. argue with the friendC. break up with the friendD. explain things calmly14. The author will listen to a friend when .A. he is against the truthB. he doesn't tell the truthC. he is respected by a friendD. he does things in the wrong way15. What does the author mainly talk about in the text?A. How to keep friendship.B. How to avoid hurting a friend.C. How to express disagreements.D. How to deal with disagreements.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。

I’d watch as he put his personal items away: his watch, wallet, comb and car keys would always occupy the same spot on the table every time.Dad’s comb was bought when he married Mum. Every evening, he would smile, hand me the comb and say: “Be a good girl and help Daddy clean it, OK?” I was more than happy to do it. This seems amundanetask, but it brought me such joy at that time. I would excitedly turn the tap on, then brush the comb with a used toothbrush as hard as I could. Satisfied that I’d done a good job, I would proudly return the comb to Dad. He would smile at me, and place the comb on top of his wallet.About two years later, Dad started his own business. I started primary school. That was when things started to change. Dad’s business wasn’t doing so well, and he didn’t come home as much as he used to. Over the years, I stopped waiting for him to come home.Today, I’ve graduated from college and Dad’s business are better now. Yet the uncomfortable silence between Dad and me continued. Two days before my birthday last year, Dad came home early and said to me, “Hey, would you like to help me clean my comb?” I looked at him a while, then took the comb and headed to the sink. It’s a new comb. I hadn’t noticed that he’d changed it. I brushed the comb, and it hit me then: why, as a child, helping my dad clean his comb was such a joy.I passed the clean comb back to Dad. This time, I noticed my day has aged. But his smile is still as heartwarming as before. Dad carefully places his comb on top of his wallet. After so many years, I guess some things never change. And for that, I’m glad.4.

My Memory with My Dad.D. I Love My Family Members.CA new study finds almost one third of the world’s population is overweight. Since 1980, obesity rates(肥胖率)in children and adults have doubled in 73 countries, making people more worried. And rates are increasing in many other countries. Obesity is increasing faster in children than adults in many nations, including Algeria, Turkey and Jordan, the report said. But the world's weight problem is growing in both rich and poor countries alike. Researchers say an increasing number of people are dying of related health problems in what they called a "disturbing global public health problem."Researchers studied health information from 1980 through 2015. They examined obesity rates, average weight gain in 195 countries. They found that obesity rates are three times greater among youth and young adults in countries like China, Brazil and India. Almost 108 million children and more than 600 million adults were found to be overweight. Egypt had the highest number of overweight adults in 2015. Vietnam had the least. In the same year, the United States had the highest number of overweight children, and Bangladesh had the least.Yet hunger remains a problem in many areas. The United Nations said that almost 800 million people, including 300 million children, go to bed hungry each night. Experts said poor diets and lack of physical activity are mainly to blame for the rising numbers of overweight people.Growing populations have led to rising obesity rates in poor countries. Often, poor people will eat processed(加工的) foods instead of choosing a diet rich in vegetables.The London-based Overseas Development Institute studied the price of food in five countries: Britain, Brazil, China, Mexico and South Korea. It found that the cost of processed foods like ice creamand hamburgers has fallen since 1990. But the cost of fresh fruits and vegetables has gone up.8. What do we know about obesity in the world?A. It is worryingB. It is given no attentionC. It has been successfully solvedD. It is more serious among old people9. Which country has the most overweight children in 2015?A. AmericaB. VietnamC. EgyptD. Bangladesh10. What is one of the reasons why people get overweight?A. HungerB. Poor dietC. Diets with vegetablesD. Eating too much fruit11. Which ofthe following can be the best title for the text?A. It’s Important to Have a Balanced DietB. How Can We Lose Weight and Keep Fit?C. Is It Necessary for Us to Eat Fresh Vegetables?D. Nearly One Third of People in the World Are Overweight.DThe health benefits of staying active are already well-known. It can help you manage weight, keep blood sugar levels down and reduce risk factors for heart disease.Now, a new study suggests that regularly playing sports, especially badminton or tennis, is not only healthy but also reduces your risk of death, at any age, by approximately 50%. This is a big scale population study to explore the health benefits of sports in terms of death rate. The study evaluated responses from 80, 306 adults aged 30 and above inEnglandandScotland, who were surveyed about their health, lifestyle and exercise patterns.After adjusting factors such as age, sex, weight, smoking habits, alcohol use, education and other forms of exercise besidesthe named sports, the researchers compared the risk of death among people who took part in a sport to those who didn’t. The percentage of reduced risk of death was found to be: 47% for racket（球拍）sports, 28% for swimming and 15% for cycling.In addition to this, the study didn’t find any significant reduction in the risk for sports like running and football. The findings also exposed that over 44% of the participants met the guidelines for the recommended exercise levels to stay fit and healthy, which amounts to 150 minutes of moderate(适度的) physical activity in a week.Does this mean you stop running or playing football and switch to tennis instead? Every kind of sport and physical activity has different physical, social and mental benefits attached to it. The apparent lack of benefits of running and football could result from several variables that were not taken into account.Being active helps you feel happier and live longer. So, the most important step is to take part in any kind of sport that you are likely to enjoy and follow in the long term.12. How is the study conducted?A. By doing comparative experiments.B. By analyzing previous data.C. By evaluating survey information.D. By tracking participants for a long time.13. What does the underlined part “the named sports” refer to?A. Ball sports.B. Racket sports.C. Individual sports.D. Traditional sports.14. What can we infer from paragraph 5?A. Few people will play football.B. Tennis will become more popular.C. The result of this study is wrong.D. The study needs to be further improved.15. What does the author advise people to do?A. Stick to any sport that you like.B. Play badminton and tennis only.C. Stop running and playing football.D. Do any sport according to guidelines.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。
2021届西安市第一中学高三英语第一次联考试卷及答案
2021届西安市第一中学高三英语第一次联考试卷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APeople in the Middle Ages did eat with their hands. Personal utensils (餐具) were mostly unheard of, especially forks. There were spoons to help serve, but only special guests would receive a knife from the host. Everyone else would be expected to bring their own. Of course, eating with one's hands can be quite a sticky situation, so towels were provided to help diners stay at least somewhat clean as they ate.Still, dining was often a messy affair. At special occasions in the wealthiest households, women tended to dine alone, separate from the men. Women were expected to uphold a quality of grace. Eating greasy meat by hand would certainly not help! Once the men and women had finished their meals, they would come together to socialize.Dietary scholars of the Middle Ages believed that the foods in a meal needed to be served and eaten in order of heaviness. The lightest and most easily digested foods, such as fruits and cheeses, were eaten first to help the digestive (消化) system get started. Once digestion was underway, greens and light meats, such as lettuce, cabbage and chicken, could be eaten. Last came the heavier vegetables and meats, such as carrots, beans, beef, pork, and mutton. This method was considered the most healthful way to eat.The main and largest meal of the day was supper, and it was eaten at midday. Dinner was a light meal, and many of those in nobility (贵族) -the highest levels of the Middle Ages society-skipped breakfast altogether. Breakfast was considered unnecessary for those who did not perform physical work. Snacks and any other eating during the day were viewed the same way. Commoners, or the working class, were allowed to eat breakfast and small meals throughout the day.1. What did people in the Middle Ages usually do at the dinner table?A. They cleaned hands before meals.B. They used personal utensils.C. They had to use knives at dinner.D. They ate mostly with hands.2. What is the third paragraph mainly about?A. The order of eating foods.B. The weight of various foods.C. The principles of digesting foods.D. The list of healthy foods.3. Why did the nobility avoid eating breakfast?A. Breakfast was wasted for the nobility.B. Breakfast was viewed as unnecessary.C. Breakfast was considered as a light meal.D. Breakfast was saved for commoners.BPlanned missions to the moon need to hurry up to avoid hitting one of the busiest periods for extreme space weather, according to scientists conducting the most in-depth ever research on solar storm timing.Scientists at theUniversityofReadingstudied 150 years of space weather data to look into patterns in the timing of the most extreme events,which can be extremely dangerous to astronauts and satellites. This new research on space weather timing allows predictions to be made for extreme space weather. Therefore, it could be used to plan the timing of activities, which could be affected by extreme space weather, for example, major space missions.The researchers found for the first time that extreme space weather events are more likely to occur early in or late solar cycles-such as the one just starting. The findings may have influences on the NASA-led Artemis mission. It plans to make humans return to the moon in 2024, but can be put off to the late 2020s.Professor Mathew Owens, a space physicist at theUniversityofReading, said, “Until now, the most extreme space weather events were thought to berandomin their timing. Though there is no set pattern of the events, this research suggests they are more predictable.”In the new study, the scientists used a new method applying statistical modelling to storm timing for the first time. Previous research generally focused on how big extreme space weather events can be, based on observations of previous events. Predicting their timing is far more difficult because extreme events are rare, so there is ly little historic data to identify patterns. The findings suggest that any major planned space missions , which is beyond the next five years, will have to consider the higher probability of extreme space weather late in the present solar cycle between 2026 and 2030.4. What can we learn about the study from the first two paragraphs?A. It has lasted just 150 years.B. It doesn't refer to space weather data.C. It shows space weather has no effect on astronauts.D. It makes it possible to predict extreme space weather.5. Why might the NASA-led Artemis mission be put off?A. To research solar cycles.B. To avoid effects of space weather.C. To meet the needs of the astronauts.D. To make humans return to Earth in 2024.6. What does the underlined word “random“ in paragraph 4 probably mean?A. Irregular.B. Easy.C. Limited.D. Changeless.7. What can we infer from the last paragraph?A. The study is useful for future space missions.B. The planned space missions should be put off.C. Extreme space weather will happen before 2026.D. Previous observations make no difference to the study.CWhen I was trying to find a place where to spend my December holidays, I met by chance some cheap flights to Iceland. After checking just a few winter pictures of Iceland, I realized that the country, known as the land of fire and ice, during the cold months of the year could offer me experiences I had never had before.For sure you can’t miss the chance to go to Iceland in winter if your traveling wish list includes at least one of the crazy experiences Iceland can offer. Iceland in the North Atlantic Ocean is a paradise (乐园) for all those who want to see the northern lights, experience cold weather conditions and put themselves in geothermal (地热的) baths while the snow is falling on their head.The best way to move around Iceland is with a rental car. Distances are huge and public transport in winter is not really common out of the major towns. As we wanted to be even more convenient we decided to rent a small camper (野营车). Sleeping and cooking in a camper saved us a lot of driving, money and gave us the chance tobe always in the right place at the right time.There were also no locals and in many cases no tourist facilities (设备). For us, as we slept in a camper, it was easier. But for tourists traveling by normal cars it is necessary to check the opening times ofhotels and restaurants as many of them run just from June to September.It is amazing to experience how the weather is changing in Iceland. However, Icelanders prefer to stay insidetheir houses. They have even no time to complain about the weather in December. All they care about is Christmas. They love to decorate their houses, sing Christmas songs and eat typical Christmas food.8. Why is Iceland famous as the land of fire and ice?A. Because tourists would like to play with fire on the ice.B. Because it is too dry to easily cause fire to happen.C. Because it is hot inside a house and cold outside.D. Because there exist hot springs and freezing ice.9. What did the author think of the rented camper?A. It was not only practical but also economical.B. It was convenient but cost them more money.C. It provided the best chance to see the new country.D. It was much faster than other public transport.10. What does the last paragraph imply?A. The Icelanders prefer to live with their family.B. The joy of Christmas drives the freezing weather away.C. December is the coldest month of the year.D. The Icelanders are always positive and stay outside.11. What does this passage most probably come from?A. A textbookB. A scientific reportC. A travel magazineD. A news reportDWith 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 the stage 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.12. 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.13. 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.14. 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.15. Which of the following words can best describe Alex?A. Strong-minded.B. Warm-hearted.C. Cool-headed.D. Easy-going.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 Below Zero icecream machine uses a unique technique to freeze alcohol, which allows you to turn beers, cocktails and even spirits (烈酒) into delicious soft —serve ice cream.Rogers was trying to create a highly — caffeinated espresso ice cream flavor when he realized hecould use the same technique with alcoholic beverages. He started experimenting with various gums and stabilizers commonly used in the ice cream industry and eventually patented something called the NEA gel. It’s this magical concoction (调制品) that allows the alcohol to freeze to a near solid inside the Below Zero ice cream machine.Even though Below Zero changes the texture (质地) of beer, cocktails and even spirits, essentially turning them into soft —serve ice cream, it does not affect the alcohol contentat all. The ABV (酒精度) remains exactly the same, which means you can get drunk on ice — cream just as you would on the same concoctions in liquid form.Will Rogers claims that it takes around 30 minutes for beer to go from liquid to ice cream form, but higher alcohol content drinks take longer. Essentially, the higher the alcohol level, the longer the wait.The American inventor plans to sell Below Zero ice cream machines to bars and breweries wanting to surprise their patrons. Metro reports that machines will sell for about 6,000.4. What’s the name of the machine which can change beer and spirits into ice cream?A. Will RogersB. WDS Dessert StationsC. HinkleyD. Below Zero5. What makes alcohol to freeze to a near solid inside the machine?A. gums.B. stabilizers.C. NEA gel.D. ABV.6. What can we know from the passage?A. The machine can change all liquids into ice cream.B. It takes 20 minutes for beer to change into ice cream.C. The higher the alcohol level, the shorter the wait will be.D. The machine changes the texture of beer, cocktails and even spirits.7. What can we infer from the passage?A. The machine affects the alcohol content.B. You can get drunk if you have ice—creams made from spirits.C. The American inventor doesn’t want to sell themagical machine.D. Bars and breweries will not become potential buyers of the machine.C“Your mind is a garden; your thoughts are the seeds. The harvest can either be flowers or weeds,” William Wordsworth wrote. In the above quote, William suggests that the process of gardening mirrors human life. Depending on what we “plant” in our lives, we bloom (生长茂盛) or don’t. Before you start to work in your garden, it’s necessary to have a vision for it. Thinking of what youwant to grow in your garden and how to lay it out is a good first step in making your vision a fruitful reality. In life, you should consider what you want to create and what you want to achieve, because your mind-garden is like the white paper and the possibilities are endless. Regardless of what you choose to plant, poor soil isn’t suitable for growth. This is why gardeners take the time and energy to upgrade the soil before planting. So, creating the right soil is important to the realization of your goals and dreams. Fortunately, there are countless ways to make your personal bedrock better. Getting an education is one of the most effective ways, which can help you enrich your life’s soil.You don’t have to be an enthusiastic gardener to understand the meaning of “You reap(收获) what you sow.” When a gardener wants tomatoes, they just need to plant tomato seeds. It’s a very clear act that produces an expected result. Each of us has the power to decide which “life seeds” to plant. For example, if you plant ill seeds, it's likely that you’ll experience pain in return. Contrarily, if you plant seeds of kindness and understanding, your life will bloom with happiness and love.A gardener’s trulyarduouswork begins after the seeds are in the ground because a garden requires a lot of care and attention. Regular watering and weeding are required for a healthy garden. So, to ensure your dreams takeroot, you should be devoted, aware, and present. After countless hours and energy spent, the crops have grown well and are finally ready to be harvested.8. What is important before gardeners break ground in their gardens?A. Receiving some training in planting.B. Drawing up a good plan for their gardens.C. Having the courage to accept the worst outcome.D. Doing research on the common local garden plants.9. What is compared to getting education by the author?A. Improving the condition of the soil.B. Growing your most favorable plants.C. Taking care of the plants in your garden.D. Selecting proper goals in gardening work.10. What does the author want to express in Paragraph 3?A. Your quality of life depends on your positive action.B. Your experience can help you understand plants better.C. Your choice of soil is an important part in your gardening.D. Your knowledge of planting will make you a successful gardener.11. What does the underlined word “arduous” in Paragraph 4 probably mean?A. BeneficialB. CreativeC. Boring.D. ToughDWhy isn’t science better? Look at career incentive(激励).There are oftensubstantial gaps between the idealized and actual versions of those people whose work involves providing a social good. Government officials are supposed to work for their constituents. Journalists are supposed to provide unbiased reporting and penetrating analysis. And scientists are supposed to relentlessly probe the fabric of reality with the most rigorous and skeptical of methods.All too often, however, what should be just isn’t so. In a number of scientific fields, published findings turn out not toreplicate(复制), or to have smaller effects than, what was initially claimed. Plenty of science does replicate — meaning the experiments turn out the same way when you repeat them -but the amount that doesn’t is too much for comfort.But there are also waysin which scientists increase their chances of getting it wrong. Running studies with small samples, mining data for correlations and forming hypotheses to fit an experiment’s results after the fact are just some of the ways to increase the number of false discoveries.It’s not like we don't know how to do better. Scientists who study scientific methods have known about feasible remedies for decades. Unfortunately, their advice often falls ondeaf ears.Why? Why aren't scientific methods better than they are? In a word: incentives. But perhaps not in the way you think.In the 1970s, psychologists and economists began to point out the danger in relying on quantitative measures for social decision-making. For example, when public schools are evaluated by students’ performance on standardized tests, teachers respond by teaching “to the test”. In turn, the test serves largely as of how well the school can prepare students for the test.We can see this principle—often summarized as “when a measure becomes a target, it ceases to be a good measure”—playing out in the realm of research. Science is a competitive enterprise. There are far more credentialed (授以证书的) scholars and researchers than there are university professorships or comparably prestigious research positions. Once someone acquires a research position, there is additional competition for tenure grant funding, and support and placement for graduate students. Due to this competition for resources, scientists must be evaluated and compared. How do you tell if someone is a good scientist?An oft-used metric is the number of publications one has in peer-reviewed journals, as well as the status of those journals. Metrics like these make it straightforward to compare researchers whose work may otherwise be quite different. Unfortunately, this also makes these numbers susceptible to exploitation.If scientists are motivated to publish often and in high-impact journals, we might expect them to actively try to game the system. And certainly, some do—as seen in recent high-profile cases of scientific fraud(欺诈). If malicious fraud is the prime concern, then perhaps the solution is simply heightened alertness.However, most scientists are, I believe, genuinely interested in learning about the world, and honest. The problem with incentives is that they can shape cultural norms without any intention on the part of individuals.12. Which of the following is TRUE about the general trend in scientific field?A. Scientists are persistently devoted to exploration of reality.B. The research findings fail to achieve the expected effect.C. Hypotheses are modified to highlight the experiments' results.D. The amount of science that does replicate is comforting.13. What doesdeaf earsin the fourth paragraph probably refer to?A. The public.B. The incentive initiators.C. The peer researchers.D. The high-impact journal editors.14. Which of the following does the author probably agree with?A. Good scientists excel in seeking resources and securing research positions.B. Competition for resources inspires researchers to work in a more skeptical way.C. All the credentialed scholars and researchers will not take up university professorships.D. The number of publication reveals how scientists are bitterly exploited.15. According to the author, what might be a remedy for the fundamental problem in scientific research?A.

On the Internet.BFrom skateboarding to Fleetwood Mac, TikTok users got creative in a pandemic (流行病) year with new songs, dances and shows in 60 seconds or less.The social mediavideo app on Wednesday shared its list of top 100 videos, creators and trends in America during 2020. “These videos brought joy and inspiration to millions of Americans in the rough year,” said Kudzi Chikumbu, director of creator community at TikTok.The platform has been widely associated with Generation Z (people born after 1996), millennials (people born in the 1980s or 1990s) and influencers who have started careers based on the shared videos.The Weeknd'sBlinding Lightsand Jason Derulo's Savage Loveinspired TikTok dance challenges that made them among the top songs used on the app.For some TikTok creators, the pandemic itself became inspiration to create a connection with other users. Comedian Caitlin Reilly used the app during quarantine (隔离) to make fun of those annoying coworkers for one of the top liked videos. And singer Curtis Roach made an song for the endless days at home with his song Bored in the House.The second most popular video was an Idaho man named Nathan Apodaca who shot to fame after coolly singing Dreams by Fleetwood Mac, while skateboarding on a highway.But the most liked TikTok video was awarded to Bella Poarch with 45 million followers, who created a simple but interesting video with a few seconds of well-timed head nods and eye rolls.While the app might be designed for youth, Chikumbu said that the growth of TikTok this year has pushed it more into mainstream culture. “You're seeing everyone from the teenager to the college students with their parents and then their grandparents all making videos,” said Chikumbu. “And now TikTok trulytranscendsgenerations, particularly in this year when people had a lot of time to dig in and not only watch, but try.”4.

Makes use of.B. Goes beyond.C. Calls on.D. Takes charge of.CYour house may have an effect on your figure.Experts say the way you design your home could play a role in whether you pack on the pounds or keep them off. You can make your environment work for you instead of against you. Here are some ways to turn your home into part of your diet plan.Open the curtains and turn up the lights. Dark environments are more likely to encourage overeating, for people are often less selfconscious (难为情) when they’re in poorly lit places—and so more likely to eat lots of food. If your home doesn’t have enough window light, get more lamps and flood the place with brightness.Mind the color1 s. Research suggests warm color1 s fuel our appetites. In one study, people who ate meals in a blue room consumed 33 percent less than those in a yellow or red room. Warm color1 s like yellow make food appear more appetizing, while cold color1 s make us feel less hungry. So when it’s time to repaint, go blue.Don’t forget the clock—or the radio. People who eat slowly tend to consume about 70 fewer calories (卡路里) per meal than those who rush through their meals. Begin keeping track of the time, and try to make dinner last at least 30 minutes. And while you’re at it, actually sit down to eat. If you need some help slowing down, turn on relaxing music. It makesyou less likely to rush through a meal.Downsize the dishes. Big serving bowls and plates can easily make us fat. We eat about 22 percent more when using a 12inch plate instead of a 10inch plate. When we choose a large spoon over a smaller one, total intake (摄入) jumps by 14 percent. And we’ll pour about 30 percent more liquid into a short, wide glass than a tall, skinny glass.8. The text is especially helpful for those who care about ____________.A. their home comfortsB. their body shapeC. house buyingD.healthy diets9. A home environment in blue can help people ______________.A. digest food betterB. reduce food intakeC. burn more caloriesD. regain their appetites10. What are people advised to do at mealtimes?A. Eat quickly.B. Play fast music.C. Use smaller spoons.D. Turn down the lights.11. What can be a suitable title for the text?A. Is Your House Making You Fat?B. Waysof Serving DinnerC. Effects of SelfConsciousnessD. Is Your Home Environment Relaxing?DHardware in general,and smartphones in particular,have become a huge environmental and health problem in the Global South's landfill sites(垃圾填埋场).Electronic waste(e-waste) currently takes up 5 percent of all global waste,and it is set to increase rapidly as more of us own more than one smartphone,laptop and power bank They end up in places like Agbogbloshie on theoutskirts of Ghana's capital,Accra. It is the biggest e-waste dump in the world,where 10,000 informal workers walk through tons of abandoned goods as part of an informal recycling process.They risk their health searching for the precious metals that are found in abandoned smartphones.But Agbogbloshie should not exist.The Basel Convention,a 1989 treaty,aims to prevent developed nations from unauthorized dumping of e-waste in less developed countries.The e-waste industry,however,circumventsregulations by exporting e-waste labelled as "secondhand goods' to poor countries like Ghana,knowing full well hat it is heading for a landfill site.A recent report found Agbogbloshie contained some of the most dangerous chemicals.This is not surprising: smartphones contain chemicals like mercury（水银）,lead and even arsenic(砷).Reportedly, one egg from a free-range chicken in Agbogbloshie contained a certainchemical which can cause cancer and damage the immune system at a level that's about 220 times greater than a limit set by the European Food Safety Authority(EFSA).Most worryingly,these poisonous chemicals are free to pollute the broader soil and water system.This should concern us all, since some ofGhana's top exports are cocoa and nuts.Some governments have started to take responsibility for their consumers' waste.For example,Germanyhas started a project that includes a sustainable recycling system at Agbogbloshie,along with a health clinic for workers.However,governments cannot solve the problem alone, as there is an almost limitless consumer demand for hardware,especially when governments' green policies are focused on issues like climate change.Only the manufacturers can fix this.A more economically sustainable and politically possible solution is through encouraging hardware manufacturers to make the repair, reuse and recycling of hardware profitable,or at least cost-neutral12. What can we infer from Paragraph 2?A. Electronic waste requires more landfill sites acrossGhana.B. Electronic waste is too complex to get fully recycleC. Electronic products need to be improved urgentlyD. Electronic pollution is a burning question in Agbogbloshie13. What does the underlined word "circumvents"in Paragraph 3 mean?A. AbolishesB. TightensC. Brings inD. Gets around14. What should be the best concern according to the text?A. The thread of polluted food around the worldB. The damage of chicken’s immune systemC. The lack of diversity inGhana's exportsD. The violation of EFSA's standards15. What does the author think is the best solution to the e-waste problem?A. Manufacturers' developing a sustainable hardware economyB. Governments’ adjusting their green policies about e-waste.C. Reducing customers' demands for electronic productsD. Manufacturers’ urging the government to make effective policies to ensure more profit.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。
2021年西安市长安区第一中学高三英语第一次联考试题及答案解析
2021年西安市长安区第一中学高三英语第一次联考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AThe Internet has revolutionized our lives to such an extent (程度) that for most people, the global network has become more than just a tool but rather an important aid in everyday life. More and more people go online as wireless networks have brought the Internet closer and closer: it’s on our mobile phones, in our cars and TV sets, in hospital surgery rooms and in fishing boats that battle the waves of the Atlantic.And this revolution has brought along with it a new way of shopping. Both big and small, e-business websites have flooded the Internet by the hundreds of thousands. Anything you can buy from a brick and mortar store (实体店) you can also buy online: from food and clothes to toys, no matter what you’re looking for, you’re bound to find the right online store with just a few clicks of the mouse. You can use the Internet to find new suppliers, post buying requests or search for products and services.This revolution has affected brick and mortar business owners greatly. And what was their reaction? They’ve opened online stores to go hand in hand with their conventional business.But do the big players have reasons to be afraid? Are we going to start seeing ghostly, deserted Walmarts (沃尔玛) across the country? Probably not in the near future but the day will come when most people will just stop shopping offline anymore. A trip to Walmart wastes time, burns gas.The recent advancements in mobile technology and the introduction of mobile phones with enhanced (提高的) web capabilities have even made some people order their groceries when they get out from work and have them delivered at their doorstep by the time they get home. And as “Time is money”, this practice is lifesaving for people whowork two jobs.Technology will continue to advance and e-business will follow closely in its footsteps. Everything will become easier and less time consuming, leaving us more time to enjoy the things that really matter in life: the ones we love, our friends and hobbies.1. What is Paragraph 1 mainly about?A. The popularity of mobile phones.B. The great influence of the Internet.C. The importance of the Internet.D. The function of the global network.2. In response to the threat of online business, the brick-and-mortar store owners________.A. have stopped their traditional businessB. have started their dislike of the InternetC. have established their own websiteD. have opened their online stores3. What would be the best title for the passage?A. A New Way of Shopping.B. The Internet Revolution.C. What is the Reaction to Online Shopping?D. Is Online Shopping the Future of E-business?BGlobally, people use roofs to dry out food, do their laundry and sleep. In Belfast, where we're based, there's a culture of enjoying looking down on the city from up high, because it's in a valley. But because we were a conflict area for a long time,many people didn't want to live, work or hang out in the city, and our roofs cape has been neglected.Rooftop projects can be as big or as small as you want. They can be used as social or cultural spaces, for green or blue public facilities. But it's not just about commercial opportunities; it can be as simple as an individual turning his/her city balcony into a mini garden or vegetable patch. It's not just about doing it on a rooftop because it's “cool”.It's about giving up the deep-rooted thought that roofs are off limits and embracing their challenges as opportunities. That can make a huge difference. For instance, we're helping turn the rooftop car park of a city central shopping centre into an outdoor space for employees, due to restrictions they now face indoors because of COVID-19.Using rooftops creatively allows us to cope with many of the challenges faced by cities today--be those environmental, social, technological, or cultural. At the moment,we're being forced to rethink how we use public spaces due to COVID-19. With lots of restrictions on enclosed areas, we should be acknowledging rooftops alternatives.For example,Rotterdam recently hosted a play that took place across its rooftops. Each roof lit up and hosted a different part of the drama, while residents sat and watched, listening to the action through headphones. Are there any challenges? Rain is one. Also is health and safety. But there are creative and practical solutions to all the barriers we face. In fact,the challenges are what make rooftops so exciting----because they give you even moreopportunities to be creative and solve problems. It is always a matter of trial and error.4. What can we learn about rooftops in the first two paragraphs?A. People enjoy getting together on rooftops.B. People can use rooftops to their own advantage.C. Rooftops are made good use of by locals in Belfast.D. Rooftops projects were launched for commercial reasons.5. How can rooftops benefit people in their life?A. Rooftops can be adapted to car parks.B. Rooftops help solve environmental problems.C. Rooftops can provide space for work and play.D. People can exchange their thoughts on rooftops.6. What will be possibly mentioned after the last paragraph?A. The new challenges of the future.B. Reasons for building rooftop projects.C. Exciting development of rooftop projects.D. Solutions to the challenges we are facing now.7. What is the author's purpose in writing the text?A. To introduce rooftop projects in Belfast.B. To encourage people to start rooftop projects.C. To analyze the current situation of rooftop projects.D. To offer suggestions on long-term city development.CAccording to the study posted onScienceDirect, gardening just two to three times a week increase the benefits of better well-being as much as possible and lower stress levels.The research explored why residents engaged with gardening and the extent to which they recognized any health benefits from the activity.A questionnaire was handed out electronically within theUK, with 5,766 gardeners and 249 non-gardeners responding. Data was collected on factors including garden typology（类型学）, frequency of gardening and individual awareness of health and well-being."This is the first time the dose response（剂量效应）to gardening has been tested and the evidence from thesurvey strongly suggests that the more frequently you garden, the greaterthe health benefits," said Royal Horticultural Society (RHS) lead author Dr Lauriane Chalmin-Pui. In fact, gardening every day has the same positive impact on well-being than undertaking regular and powerful exercise like cycling or running.When gardening, our brains are pleasantly entertained by nature around us. Gardening takes our attention away from ourselves and our stresses, therefore, it helps restore our minds and reduce unfavorable feelings.Improving health, however, was not the main motive power to garden, but rather the direct pleasure gardening brought to the participants."Gardening is like effortless exercise because it doesn't feel as exhausting and hard as going to the gym, for example, but we canexpendsimilar amounts of energy," Chalmin-Pui added.Most people say they garden for pleasure and enjoyment, so people who like gardening may be easy to be addicted to it. However, this sometimes may become a piece of good news, from the aspect of mental health. "We hope all the millions of new gardeners will be getting their daily gardening and feeling all the better for it. " Chalmin-Pui said in the interview.8. What can be inferred about gardening from the survey?A. Improving health is the aim of the participants.BGardening makes no difference to health.C. Health benefits from frequent gardening.D. Too much gardening always does harm to health.9. What does the underlined word "expend" mean in paragraph 7?A. Consume.B. Make use of.C. Increase.D. Save.10. Why do so many participantslike gardening?A. It isn't exhausting.B. It is good for health.C. It brings pleasure.D. It is like going to the gym.11. What is Chalmin-Pui's attitude to the new gardeners' gardening?A. Carefree.B. SupportiveC. Tolerant.D. Indifferent.DIt’s easy to do easy things, but they don’t carry the challenges and rewards of doing something difficult. Scott Kelly said he tried to express that view everywhere he went. And he spoke from experience, having spent a career that included the time as a NASA astronaut, US Navy captain, fighter pilot, and engineer.Scott spoke at the University of North Alabama, sharing stories about his experience of spending a year on theInternational Space Station (ISS). He said the physical pressure of living in weightlessness for a year was hard to describe and that the fluids(积水) in his head sometimes made him feel like he was standing on his head. It also needed some time to recover when he returned home. “My legs were weak and it would be uncomfortable to sit for a while because my body hadn’t had that pressure so long,” Scott said.He discussed life aboard including spending time with Russian astronauts. They came from different cultures. He had managed to get along well with everyone aboard as they lived together, worked together, and had to rely on each other. He thought it was one of the most rewarding things in his life.Though life there was not easy, Scott never regretted being an astronaut and going to space. He also discussed experiences growing up, admitting that he wasn’t always the greatest student but was able to overcome that through hard work and determination.“Never give up or lower your dreams. If you work for it, all things are possible. There is a zero percent chance of succeeding if you don’t even try. And when you succeed after trying hard, you’ll find it really rewarding,” Scott said in the end.12. Scott mentioned his experience in the ISS mainly to show ________.A. he enjoyed making speechesB. he was a responsible astronautC. his life in space was challengingD. the daily life of an astronaut can be boring13. What may benefit Scott most when he lived with Russian astronauts?A. He won some awards through teamwork.B. He found the fun of living in the Space Station.C. He learned to develop close relationships with others.D. He picked up some knowledge of Russian culture.14. Which of the following can best describe Scott?A. Kind and thoughtful.B. Curious and humorous.C. Easygoing and sociable.D. Hardworking and determined.15. What does the author intend to tell us from Scott’s story?A. It’s importantto have a dreamB. Easy things are also worth doingC. A suitable career leads one to success.D. Difficult things are demanding but rewarding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。

He teaches in the area where having electricity is something of a luxury and students have no access to mobile apps or computers, which became a problem when Guatemalan government had to choosedistance education for students at home because of COVID-19 inmid-March.Gerardo Ixcoy felt that he had to teach those children living far from the digital world. After all, education is a universal right. But what was the solution?Gerardo bought himself a secondhand tricycle with his savings. Once he had the tricycle, the next step was to change it into a classroom on wheels. He put a roof with a solar panel（太阳能电池板）on it, along with a screen to avoid the spread of COVID-19. He fixed a whiteboard on it so he could explain to the students the basics of primary education：math, the local language and the national language Spanish.The purpose of the solar panelis to provide constant power for a small loudspeaker so he can teach from a distance. It's a matter of respecting the healthy distance required to be safe from the virus. He, the teacher, staysoutside, and the student participates from his or her house.He tries to visit his students at least twice a week, riding his classroom — cycle. The children he serves say that, although he visits them for only a few hours a week, they look forward to it. They appreciate his visit because they know he has limited time he can devote to them. They must take advantage of it to learn.4. What happened to Gerardo Ixcoy's students because of COVID-19?A. They chose to have classes in groups.B. They had to stop all the classes.C. They continued to have classes online.D. They started to learn about computers.5. Why does the teacher stay from a distance while teaching?A. Because healthy distance is reqired.B.

Education is the key to success.CWe asked four people who watched an online talk on technology and communication by Sherry Turkle for their opinions.Fred:The talk certainly gave me plenty of food for thought about how technology is changing our behaviour. People are constantly multitasking, whether it be emailing during meetings or texting in the checkout queue. It’s as if we can’t bear to miss out on what our online friends are up to, so we juggle the real and online world. My greatest concern is that we don’t give our brains a chance to switch off. It’sthese precious momentswhen we actually process information that helps us make important decisions.Jeremy:It was a fascinating talk and the speaker really hit the nail on the head with a couple of things. Take parental influence, for instance. How can we expect teenagers not to text while doing their homework when they witness their parents posting on social media while cooking the evening meal or waiting at a red light?Kath:So much of what the speaker said rang true. I honestly believe there’s a danger that the more connected we are, the more isolated we feel. I don’t think this is such an issue for my generation who’ve lived without technology for so long. We know how to be alone. But the under 20s are another kettle of fish. They’re so busy communicating that they never experience the feeling of solitude and run the risk of not learning how to enjoy their own company.Carl:I’m not sure to what extent I agree that people are more alone, but the way we communicate has certainly evolved. The speaker makes a good point about how we’re getting used to talking with machines like Siri or robots, which are totally lack of experience of human life. But despite such limitations, we seem to be expecting more from technology and less from each other.8. What does the underlined phrase “these precious moments” in paragraph 2 refer to?A. When our brains are free.B. When we emailing during meeting.C. When we texting in the checkout queue.D. When we juggle the real and online world.9. What suggestion may Jeremy give to the parents?A. Accompany their children when they are doing homework.B. Prevent their children using phone while doing homework.C. Set a good example for their children on using phone properly.D. Stop posting on social media in face of their children.10. What does Kath worry about the under 20s generation?A. They communicate more with others.B. They use more technology.C. It’s difficult for them to find companies.D. They don’t know how to be alone.11. What is Carl’s attitude towards the use of technology in communication?A. Favorable.B. Intolerant.C. Doubtful.D. Indifferent.DIf you’re looking for a reason to care about tree loss, this summer’s record-breaking heat waves might be it. Trees can lower summer daytime temperatures by as much as 10 degrees Fahrenheit, according to arecent study.But tree cover in US cities is shrinking (缩减). A study published last year by the US Forest Service found that we lost 36 million trees annually from urban and rural communities over a five-year period. “If we continue on this path, cities will become warmer, more polluted and generally unhealthier for inhabitants,” said David Nowak, a senior US Forest Service scientist and co-author of the study. Nowak says there are many reasons why our tree cover is declining, including hurricanes, tornadoes, fires, insects and disease. But the one reason for tree loss that humans can control is sensible development.Nowak says there is a downside to trees too, such as pollen allergy (花粉过敏) or large tailing branches in storms, and people don’t like sweeping leaves. But, he says, there are ways cities and counties can manage trees to help communities thrive (繁荣). Urban forests especially need our help to replace fallen trees. Unlike rural areas, it is very difficult for trees to repopulate themselves in a city environment with so much pavement and asphalt (沥青). “A lot of our native trees can’t actually find a place to drop a seed so they can regenerate,” explains Greg Levine, co-executivedirector of Trees Atlanta. “That’s why the community has to go in and actually plant a tree because the areas just aren’t natural anymore.”Nowak says the first step is caring for the trees on your own property (财产). “We think we pay for our house, and sowe must maintain it. But because we don’t pay for nature, we don’t need to. And that’s not necessarily true.”12. Why does the author mention “trees can lower summer daytime temperatures”?A. To tell the temperatures in summer are high.B. To explain the reason of tree loss.C. To tell trees are helpful.D. To introduce the topic.13. How can humans control tree loss according to Nowak?A. Develop cities in reasonable ways.B. Prevent fires form damaging trees.C. Improve climate to let trees grow.D. Decrease insects in cities.14. Why do forests in cities need our help?A. Because trees don’t grow in a city environment.B. Because native trees don’t drop seeds any more.C. Because trees in urban areas can’t regenerate naturally.D. Because humans want to plant more trees.15. What is the purpose of this passage?A. Describe the importance of trees in cities.B. Appeal people to protect trees in their surroundings.C. Ask people to plant trees with the author.D. Show the number of trees in theUSis declining.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 smaller satellite is equipped with a magnetic (磁力的) plate which allows the chaser todock withit.The two stacked spacecraft will perform three tests once in orbit, each of which will involve the servicer satellite releasing and then recapturing the client satellite. The first test will be the simplest, with the client satellite drifting a short distance away and then being recaptured. In the second test, the servicer satellite will set the client satellite tumbling before catching up with it and matching its motion to grab it.Finally, if those two tests go well, the chaser will live up to its name by letting the client satellite float a few hundred metres away before finding it and attaching to it. All of these tests will be performed autonomously, with little to no human input once they are set in motion.“These kinds of demonstrations have never been done before in space - they are very different to, say, an astronaut controlling a robotic arm on the International Space Station,” says Jason Forshaw at AstroscaleUK.“This is more of an autonomous mission.” At the end of the tests, both spacecraft will burn up in Earth's atmosphere.If companies wanted to use this capability, they would have to attach a magnetic plate to their satellites so they could be captured later. Because of the growing space garbage problem, many countries now require firms to have a way to bring back their satellites once they run out of fuel or fail, so this could be a fairly simple likely plan, Forshaw says. Right now, each chaser can only nab one satellite, but Astroscale is working on a version that could drag three or four out of orbit at once.4. Which of the following can replace the underlined word "dock with" in Paragraph 2?A. Deal with.B. Keep up with.C. Join together.D. Crash.5. Why many countries now require firms to have a way to bring back their satellites?A. Because of the growing space waste problem.B. Because the frequency of space launches are dramatically increasing.C. Because they can earn large profits from it.D. Because Astroscale has found a new method of capturing the space garbage.6. What will Astroscale do to solve the space junk problem?A. An astronaut controls a robotic arm on the International Space to capture the “client” satellite.B. Through a magnetic plate remotely controlled by humans on the ground to catch the “client” satellite.C. Finding the "client "satellite and attaching to it with a magnetic plate automatically.D. Tumbling to match the motion of “client satellite the drag three or four satellites out of its orbit into atmosphere.7. What can we infer from the passage?A. People will bum the space junk up in Earth's atmosphere in the future.B. Japan andRussiawill conduct space debris cleanup experiment together.C. These kinds of demonstrations have never been done before.D. The demonstration mission will be divided into three phases.CGetting rid of dirt, in the opinion of most people, is a good thing However, there is nothing fixed about attitudes to dirt.In the early 16th century, people thought that dirt on the skin was a means to block outdisease, as medical opinion had it that washing off dirt with hot water could open up the skin and let ills in. A particular danger was thought to lie in public baths. By 1538, the French king had closed the bath houses in his kingdom. So did the king ofEnglandin 1546. Thus began a long time when the rich and the poor inEuropelived with dirt in a friendly way. Henry IV, king ofFrance, was famously dirty. Upon learning that a nobleman had taken a bath, the king ordered that, to avoid the attack of disease, the nobleman should not go out.Though the belief in the merit(优点) of dirt was long-lived, dirt has no longer been regarded as a nice neighbor ever since the 18th century. Scientifically speaking, cleaning away dirt is good to health. Clean water supply and hand washing are practical means of preventing disease. Yet, it seems that standards of cleanliness have moved beyond science since World War II. Advertisements repeatedly sell the idea: clothes need to be whiter than white, cloths ever softer, surfaces to shine. Has the hate for dirt, however, gone too far?Attitudes to dirt still differ hugely nowadays. Many first-time parents nervously try to warn their children off touching dirt, which might be responsible for the spread of disease. On the contrary, Mary Ruebush, an American immunologist(免疫学家), encourages children to play in the dirt to build up a strong immune system. And the latter position is gaining some ground.8. The kings ofFranceandEnglandin the 16th century closed bath houses because .A. they lived healthily in a dirty environmentB. they thought bath houses were too dirty to stay inC. they considered bathing as cause of skin diseaseD. They believed disease could be spread in public baths9. Which of the following best describes Henry IV’s attitude to bathing?A. CuriousB. AfraidC. ApprovingD. Uninterested10. How does the passage mainly develop?A. By following the order of time.B. By making comparison.C. By providing examplesD. By following the order of importance.111. What is the author’s purpose in writing the passages?A. To call attention to the danger of dirt.B. To introduce the history of dirt.C. To present the change of views on dirt.D. To stress the role of dirt.DJoshua Nelson, 18, fromMissouri, is graduating fromSt. CharlesWestHigh Schoolthis week and will be attendingSoutheastMissouriStatein the fall. He had saved upmoney to pay for his tuition, but when he received the college's President's Scholarship, he decided to take his savings and donate it to other students in need.“It comes from my family education and faith," Nelson said. "I've always lived by strong principles as far as being a cheerful giver andhaving an open handwhen it comes to giving back so I feel like that really motivated me.”SEMO's President's Scholarship is the school’s most celebrated, and is only awarded to five top students annually. Nelsonsaid he sat down and outlined how a scholarship could work to help future students who need financial assistance for college. Originally the plan was to give away $ 1,000 the one time, but then he met up with his counselor (顾问), Yolanda Curry, to work outa game plan.“I wasn't expecting it at all!” Curry said. "He told me he had a great idea and wanted to share it with me. I could tell he was really excited.Nelson, in association with his high school, set up the Joshua Nelson Leaders In Action Scholarship fund. Each year, $1,000 will be awarded to a senior. The money will come from donations, of which there have been $16,000 so far — for a total of $17,435 at last count, according to the school. With the money already in the fund, there's enough to give out a scholarship each year for over a decade. The first scholarship was awarded on June 1 to Darrell Montalvo-Luna. As the first recipient, his scholarship was $2,000.“Joshua has the heart of a servant leader. He leads by example and he's genuinely excited when good things happen for other people," Curry said. "He's an encouragement — he's good at building others up and does what he can to help encourage and motivate those around.12. What did Nelson's initial donation come from?A. His scholarship.B. His savings.C. His pocket money.D. His wages.13. What does the underlined phrase "having an open hand" in paragraph 2 mean?A. Ambitious.B. Courageous.C. Generous.D. Cautious.14. How did Curry feel when hearing Nelson's idea?A. Shocked.B. Confused.C. Excited.D. Delighted.15. What can be inferred about the Joshua Nelson Leaders In Action Scholarship fund?A. It never supports high school students.B. It was set up more than ten years ago.C. It was founded by Nelson and Curry.D. It is going very smoothly.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。
2021年西安市长安区第一中学高三英语模拟试卷及答案
2021年西安市长安区第一中学高三英语模拟试卷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AFor some people, there’s no better companion than mans best friend-a dog. This four-legged pet can bring comfort and joy and provide much- needed exercise for you when it needs walkies! This probably explains why dog ownership increased last year because people spent more time at home during he CovID-I9 lockdown.However, as demand for a new dog increased, so did the price tag. Popular breeds, such as Cockapoos and Cocker Spaniels, saw even sharper price increases, and puppies have been selling for $3,000 or more.Animal welfare charities fearthat high prices could encourage puppy farming, smuggling (走私) or dog theft. An investigation found some breeders have been selling puppies and kittens on social media sites--something charities have called “extremely irresponsible”.But despite some new owners purchasing a dog legally, maybe from a rescue center or registered breeder, they’ve proved to be ill-prepared for life with a new pet, and the pet itself has found it hard tocome to terms withlife in a new home.Looking to the future, there are concerns about the welfare of these much-loved pets. Lan Alkin manager of the Oxfordshire Animal Sanct uary in the UK, notes: “At the moment, the dogs are having a great time, but separation anxiety could still surface when people go back to work.” And Cliare Calder from the UKs Dogs Trust rescue charity says, “The economic situation also means that some people may find they can’t afford to look aftera dog.” The message is not to buy a dog in haste and to pick one that fits into our lifestyle.1. The greater demand for dogs can cause the following problems except ________.A. illegal trade of dogsB. less dog farmingC. high prices of dogsD. online sale of dogs2. What does the underlined phrase"come to terms with"in paragraph 4 mean?A. Fit in withB. Go in forC. Make up for.D. End up with3. What can we learn from the last paragraph?A. Despite the problems, dogs are living happily.B. The writer has a positive attitude towards dogs future.C. Experts are worried that dogs will be unaffordable to people.D. The writer advises people to think twice before keeping dogs as pets.B“Tell her,” I whispered to my daughter as she pressed her body against mine. She folded my free arm around her little shoulders while I finished loading the groceries onto the conveyer belt.I smiled at the young cashier who had a butterfly knot tied to her black ponytail(马尾辫). My daughter was right when she'd whispered to me, “Her hair is so pretty.”“Tell her,” I repeated witha gentle push. My girl only dug her pink cheeks deeper into my side as she nervously twisted the edge of my sleeve in her small fist.The cashier looked down at my daughter, her expression showing a little concern. “My daughter thinks your hair is beautiful.” I explained.The cashier's face lit up. “You do?” This led my little one out of her hiding place. She looked up and nodded.“Thank you so much! You made my day,” the cashier said with a smile brilliant enough to compete with her highlights. My daughter returned it with a shining smile of her own.As I walked out of the store, holding my daughter's hand, I stole a glance back at the young woman. Her energy was clearly brighter now than it had: been when we first entered her line.After loading my groceries in the trunk, I climbed into the driver's seat. It was then that my daughter made a declaration, “Mom, I think I'm going to start telling everyone when I like their hair.” “You should, honey.” And she did. She still does.It's a rare occasion if we make a trip out in public without her telling someone that she loves their hair, or nails, or shirt, or shoes. To be honest, I think she even does so more than me. And it's one of my favorite things about this girl. She learned, at a very young age, that by simply telling people when you see beauty in them, you can draw out the beauty of human connection.4. Why was the author's daughter nervous in the store?A. She was frightened of the cashier.B. She was too shy to express herself.C. She was unable to pay the groceries.D. She was unhappy to greet a stranger.5. What made the cashier more energetic in her work?A. The praise from a little girl.B. The support of the customers.C. The competition environment.D. The understanding of a mother.6. What does the author think of her daughter now?A. Kind and independent.B. Lively and cheerful.C. Careful and generous.D. Smart and proud.7. What is the best title of the text?A. The Beauty Of Good MannersB. The Power In Raising Others UpC. A Girl's New Way OutOf TroubleD. A Mother's Love For Her DaughterCWhen you walk on a sandy beach, it takes more energy than striding down a sidewalk — because the weight of your body pushes into the sand. Turns out, the same thing is true for vehicles driving on roads. The weight of the vehicles creates a very shallow indentation (凹陷) in the pavement (路面) — and it makes it such that it’s continuously driving up a very shallow hill.Jeremy Gregory, a sustainability scientist at M.I.T. and histeam modeled how much energy could be saved — and green-house gases avoided — by simply stiffening (硬化) the nation’s roads and highways. And they found that stiffening 10 percent of the nation’s roads every year could prevent 440 megatons of carbon dioxide equivalent emissions over the next five decades — enough to offset half a percent of projected transportation sector emissions over that time period. To put those emissions savings into context — that amount is equivalent to how much CO2 you’d spare the planet by keeping a billion barrels of oil in the ground — or by growing seven billion trees — for a decade.The results are in the Transportation Research Record.As for how to stiffen roads? Gregory says you could mix small amounts of synthetic fibers orcarbon nanotubes into paving materials. Or you could pave with cement-based concrete, which is stiffer than asphalt (沥青).This system could also be a way to shave carbon emissions without some of the usual hurdles. Usually, when it comes to reducing emissions in the transportation sector, you’re talking about changing policies related to vehicles and also driver behavior, which involves millions and millions of people — as opposed to changing the way we design and maintain our pavements. That’s just on the order of thousands of people who are working in transportation agencies. And when it comes to retrofitting (翻新) our streets and highways —those agencies are where the rubber meets the road.8. Why does the author mention “walk on a sandy beach” in paragraph 1?A. To present a fact.B. To make a contrast.C. To explain a rule.D. To share an experience.9. What suggestion does the author give to reduce CO2 emissions?A. Hardening the road.B. Keeping oil in the ground.C. Growing trees for decades.D. Improving the transportation.10. What is the advantage of this suggestion?A. Gaining more support.B. Consuming less money.C. Involving more people.D. Facing fewer usual obstacles.11. What does the underlined part mean in the last paragraph?A.Those agencies are likely to make more rules.B. Those agencies will change some related policies.C. Those agenciesmight put more rubber tires on the roads.D. Those agencies will play a key role in making this happen.DRecycling plastic has always been a stop-start effort, and the wide variety of plastics we produce, the pollution from waste, and other limitations make recycling an economic(经济) problem. It’s estimated(估计)only 9% of plastic ever created has been recycled. But with the help of a chemical process, Canadian Miranda Wang and her company BioCellection want to change that.Stability is one of plastic greatest qualities and downside. There's limited evidence that some plastics can biodegrade (生物降解)but largely photo-plastics degrade in the sun. It’s a long process, and the truth is that we can only estimate how long it takes. Wang is looking to break the inaction and BioCellection's task is to make most plastic waste recyclable.She outlines two current methods. One is to take plastics like water bottles, wash them, cut them, melt and reconstitute them. “That's a very limited process” she says, due to the requirement that plastics be “clean” . The other, which can handle dirtier plastics and a level of pollution, is called hydrolysis(热解). Intense heat is applied to break down plastics so they can be reused as oils for energy, but “it’s not economical,’’ she says.BioCellection’s solution builds on research from over ten years ago, Wang explains, when a US studydiscovered pure polyethylene powder (聚乙烯粉)could be broken down by a catalyst (催化剂). Wang and her co-founder Jean hit upon a bacterium being able to eat plastic. In the years since, they engineered a comparable catalyst capable of doing the same job, only faster, which even works on plastics no one else can recycle at present. “We have now found a catalyst that is much cheaper than the one that was used before, Wang says.Currently focusing on plastic films like shopping hags, the three-hour process breaks clown plastic intochemicals that can act as the building blocks for more complex plastic products.“Right now we’re able to achieve about 70% transformation from plastic waste material to these chemicals,” she adds, saying they’re working to increase that figure.12. Why has so little plastic been recycled?A. Plastic is chemically stable.B. Recycling plastic led to pollution.C. We produced various plastics.D. Most photo-plastics degrade in the sun.13. What does Wang think of the two current methods?A. Highly effective and dynamic.B. Expensive and pollution-causing.C. Limited and energy-consuming.D. Widely used and recognized.14. What did BioCellection find effective to recycle plastics?A. Polyethylene powder.B. Chemical products.C. Plastic films.D. A catalyst.15. What is the text mainly about?A. Miranda Wang and her company.B. A new plastic recycling method.C. The greatest downside of plastic.D. Transformation of plastic waste.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。

2020-2021学年西安市长安区第一中学高三英语第一次联考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.BThermoelectric generators turn waste heat into electricity without producing greenhouse gas emissions, like a free lunch. But the high cost of these devices has prevented their widespread use. Now, researchers have found a way to make cheap thermae-lectrices that work just as well. The work could pave the way for greener car engines, and other energy-generating devices.“This looks like a very smart way to realize high performance,” says Li-Dong Zhao, a materials scientist. He notes there are still a few more steps before these materials can become high-performing. However, he says, “This will be used in the not too far future.”Thermoelectrics are semiconductor devices placed on a hot surface. That gives them a hot side and a cool side. If a device allows the hot side to warm up the cool side, the electricity stops flowing. A device’s success at preventing this, as well as its ability to conduct electrons, feeds into a score known as the figure of merit, or ZT.Researchers have produced thermoelectric materials with increasing ZTs. The record came in 2014 when Mercouri Kanatzidis came up with a tin selenide with a ZT of 3.1. Yet the material was too fragile to work with. “For practical applications, it’s a non-star-ter,” Kanatzidis says.Getting through that door will still take some time. The tin selenide the team makes is mixed with Na, creating a “p-type” material that conducts positive charges. To make working devices, researchers also need an “n-type” version to conduct negative charges.Zhao’s team is now working on making an n-type version. Once successful, researchers should have a clear path to making a new generation of super-efficient thermoelectric genera-tors. Those could be installedeverywhere from automobile exhaust pipes to water heaters and industrial smelters toscavengesome of the 65% of fossil fuel energy that winds up as waste heat.4. The first paragraph wants to tell us________.A. The wide use of thermoelectric generatorsB. The devices of current thermoelectric generatorsC. The reason why researchers make cheap thermoelectricsD. The greener car engines that contribute to environmental protection5. How does Li-Dong Zhao feel about cheap thermoelectric generators?A. Indifferent.B. Optimistic.C. Critical.D. Worried.6. What do you know about the research in 2014 from paragraph 4 and 5?A. It was far from a success for practical applications.B. A tin selenide with a ZT of 3.1 can be easy to work with.C. Researchers made an “n-type” version to make working devicesD. A “p-type” material made from the tin selenide conducts negative charges7. What does the underlined word “scavenge” in the last paragraph mean?A. Recycle.B. Produce.C. Clean.D. Increase.CMedha Gupta sometimes felt worried about making the 20-minute walk from the corner where the school bus dropped her off to her home in Herndon -especially during the colder months in winter.Her mother, Divya Gupta had a suggestion: write an app. Shewas half-kidding,but Medha didn't take the challenge lightly. So she set out to work.The result was Safe Travel, an app designed by Medha to help walkers feel more secure when travelling alone. Using the iPhone, a person can program it to send a warning to someone he or she trusts if he or she fails to arrive at a destination within a certain time.It was the first iOS app that Medha had created. While she didn't think much would come from the project, her effort caught the eye of judges for the annual Congressional App. Challenge, who selected her as the winner for Virginia's 10th District.The App Challenge is designed to encourage students to consider careers in science, technology, engineering, and math by experimenting with coding and computer science. Winning students are invited lo attend a reception on Capitol Hill in April and also received $250 in Amazon Web Service credits.Medha said it took her about 40 hours to design, program and test the app. As for her next app? Medha's not certain. She temporarily has her app-development ambitionson holdbecause she's busy teaching herself artificial intelligence to help deal with improper words on Facebook. Yes,she knows that there are teams of engineers probably doing the same thing. But she figures it can't hurt her own part, too.“If we see something wrong with the world, we should do something about it,” she said. “After all, the only one stopping us from doing something is ourselves. ”8. Why did Medha Gupta feel worried?A. It took a long time to walk home.B. It was difficult to write an app.C. It was colder than ever in winter.D. It was unsafe to walk home alone.9. What is Medha's attitude to her mother's challenge?A. Serious.B. Casual.C. Uncertain.D. Indifferent.10. What does the underlined phrase “on hold” in Paragraph 6 mean?A. Developed.B. Delayed.C. Achieved.D. Satisfied.11. What's the main idea of the text?A. Medha signed up for the App Challenge.B. Medha designed Safe Travel successfully.C. An app Safe Travel guides walkers home.D. The App Challenge directs students to choose careers.DWith 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.12. 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.13.

2020-2021学年西安市长安区第一中学高三英语上学期期中试卷及答案
2020-2021学年西安市长安区第一中学高三英语上学期期中试卷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A“Why do I feel cold when I have a fever?” “Why does the sun rise in the east?” I knew the day would come when my little girl Sophie would learn to talk and inevitably (不可避免地) start askingthose questions. The questions themselves weren’t worrying me. I was actually looking forward to seeing where her curiosity would lie.What was bothering (烦恼) me was whether or not I would know the answers. In the age of the smartphone, this may seem like a silly worry. The answers to almost everything would be just one Google away.Still, I struggled with how I was going to prepare to become an all-knowing mother. Then one day, it struck me: I didn’t need to have all the answers. What a great example I could set if I let my daughter know that I, too, was still learning. And I realized how much more I could learn if I took another look at things I thought I already knew the answer to with the curiosity of a child. My little girl’s mind is a beginner’s mind--- curious, open to new ideas, eager to learn, and not based on knowledge that already exists. I decided that I would deal with her questions with a beginner’s mind, too.Once I decided to become more curious, I started noticing that curiosity was becoming more important in the workplace, too. It seems that leaders don't need to have all the answers, but they do need to be curious.Curious about curiosity, I searched for answers and found Albert Einstein’s famous words, “I have no special talent. I am only passionately (热情地) curious.” We mightquibble overthe view that Einstein had no special talent, but there is one thing for certain---he wouldn't have solved the puzzles of the universe without his passionate curiosity. Then I came across another Einstein quote, “The important thing is not to stop questioning. Curiosity has its own reason or existence.”1. The advantage of having a beginner’s mind is that ________.A. people can learn much faster.B. people won't be afraid to make mistakes.C. people are willing to receive new things.D. people won't be expected to answer all questions.2. What does the example of Einstein’s words show?A. Einstein was passionate about curiosity.B. Einstein’s quotes are very famous.C. Curiosity is of great significance.D. Curiosity is more necessary than talent.3. What does the underlined phrase “quibble over” in the last paragraph probably mean?A. Fight against.B. Argue about.C. Work out.D. Agree withBScott and Daniel Harry are enjoying everyday tasks like shopping and washing for the first time following their move to an accommodation (住宿) support house in Kurwongbah, north of Brisbane last year.Disability Services Queensland’s Strengthening Non-Government Organisations project provided an accommodation support model that would enable residents (居住者) like Daniel and Scott to live more independently.The house is just one of many accommodation support services funded (资助)through the project. The five-bedroom house provides 24-hour care for up to four individuals with complex needs, including medical support. Care and staffing levels are varied and flexible, depending on each resident’s requirements.Scott and Daniel, who have a severe form of Duchenne Muscular Dystrophy, require 24-hour support in all activities of daily living. Before they moved to the house, they lived with their family. Scott says living at home was difficult as it placed a physical and emotional strain(负担) on their parents who had to wake them several times each night to reposition them or place them on breathing machines.“We were heavyhearted,” says Scott, who is planning to write a book about his life experiences. “But our parents now have a lot moretime for themselves. We now manage ourselves on a day-to-day basis.”Daniel is an enthusiastic gardener, taking care of his own vegetable garden. The men share the house with one other young man, and they go to rugby league games, meeting up with friends.Leeding Care Australia provides the care service at Kurwongbah. Manager Lee Garniss says setting up the facilities (设施) has not been without its challenges.“It is an unconventional model of care,” Lee says. “The home is Scott and Daniel’s home, however it is also a workplace for their support staff. Balancing these two requirements has been a challenge for all.”“We have experienced a bit of a learning phase over the last twelve months. However, by working as a team we try our best to meet the needs of both residents and staff and I think we have achieved the right balance.”4. What do we know about the house Scott and Daniel live in now?A. It was built by their parents.B. It can accommodate four residents.C. It belongs to a governmental project.D. It’s located in the center of Brisbane.5. Why did Scott and Daniel’s parents wake up frequently at night?A. To help them do exercise.B. They were making a lot of noise.C. To check on their breathing.D. They were under emotional pressure.6. How did Scott feel while living with his parents?A. A bit guilty.B. Quite happy.C. Very proud.D. Slightly angry.7. What was a challenge while setting up the facilities?A. Lack of fund.B. No workplace.C. Inexperienced staff members.D. Satisfying both staff and residents’ needs.CThe China International Search and Rescue Team(CISAR) was formed in 2001 and is now made up of several hundred rescue workers and about 20 police dogs. The team brings help and hope to those whose lives are changed by astorm, flood, earthquake, or any other natural disasters.After long and careful training, the team went on its first international rescue tasks in 2003. That year, the Chinese team helped save lives after earthquakes inAlgeriaandIran. It was the first time that a Chinese team had worked outsideChinawhose members won high praise for bravery and skill.Since then, the CISAR has completed many tasks. The list of people to whom help has been given is long. The team treated more than 3,000 people who were wounded in the 2006 earthquake inIndonesia, helped 2,500 wounded people after the earthquake that hitHaitiin 2010, and spent several months giving aid to over 25,000 people suffering from the 2010 floods inPakistan. On April 26, 2015, a group of 62 people from CISAR went toNepalafter the 8.1 magnitude earthquake that happened there.Rescue workers are trained to find people, treat wounds, and hand out food, water, and other supplies. They have to be able to do work that is difficult under conditions which can be very dangerous. After a disaster, there is usually no electricity or water, and there may be diseases and other dangers. Rescue workers get to save lives, but they must also bury the dead. That means they have to be strong in both body and mind.Rescue workers must have big hearts, too. It takes a lot of love and courage to risk one’s own life to save someone else’s. The members of the CISAR have plenty of both and are always ready to go wherever help is needed.8. What is the function of the numbers in Paragraph 3?A. To advertise for the CISAR.B. To add some basic information.C. To praise Recue Workers’ contributions.D. To stress the dangers Rescue Workers face.9. What is the author’s attitude towards Rescue Workers?A. Hopeful.B. Respectful.C. Curious.D. Supportive.10. What are the last two paragraphs mainly about?A. The duty rescue workers must perform.B. The qualities rescue workers must own.C. The difficulties rescue workers must go through.D. The willingness rescue workers should require.11. What may be the best title of the passage?A. China to the RescueB. How to train CISARC. Welcome to CISARD. Rescue on requestDOn March 18, 34-year-old Lance Karlson was walking on the beach and looking for somewhere toswim in Geographe Bay when he saw what he thought was a stingray (黄貂鱼) leap from the water.Realizing the creature was, in fact, an octopus (章鱼), he started filming it — just in time for the angry octopus to launch itself at him. He immediately felt a sharp pain across his left arm, followed by a second strike across his neck and upper back. His goggles (护目镜) fogged and the water around him turned dark with what he thought might have been octopus ink as he struggled back toward the shore."I was confused — it was more of a shock than a fright," said Karlson, "I might have hit on its home." Within a minute, a perfect imprint of an octopus tentacle (触手) appeared on Karlson's neck and back.A former volunteer lifeguard, Karlson rushed back to his hotelroom to find something acidic to put on the wound. All his family could grab was Coca-Cola, which his wife poured over his back and the pain disappeared."The pain went away and more than anything since then, it's been more the physical hit that was painful.... The imprint on my neck is more from the physical hit, and I guess it makes complete sense when you look at the video I took," he said.Karlson said he'd never seen an octopus that close before and watched Netflix documentary "My Octopus Teacher" after the incident to learn more about the species."They are beautiful creatures and I really hope this promotes more interest in octopuses as opposed to fear of them. I think this is a fascinating creature with clearly some very strong emotions just like we do as humans," he added.12. When did the octopus attack Karlson?A. When he was swimming in the bay.B. When he was shooting the octopus.C. When he was looking for some fish.D. When he was fighting against the octopus.13. What plays an essential role in reducing Karlson's pain?A. The lifeguard's timely help.B. Karson's wife's quick action.C. The family members' efforts.D. Karlson’s knowledge of first aid.14. What does Karlson learn from his experience?A. The octopus is dangerous.B. People should get away from the octopus.C. People need know more about the octopus.D. The physical hit from the octopus is painful.15. Which of the following might be the best title?A. Pain from Strong AttackB. First Aid for Octopus' StrikeC. Face to Face with Angry OctopusD.

If you subscribe toReader’s Digest, you can ________.A. have as many issues as possible every yearB. renew your subscription at the original rateC. get back your money for the issues not mailedD. obtain all the past issues online anytime, anywhereBSome years ago a young man applied to a large United States optical firm for a job as a lens designer. He apologized for lack of training, but on announcing that he owned two copies of the classic Conrady's Applied Optics and Optical Design, one for his office and a second for his bedside table, he was hired on the spot. Perhaps the story will be repeated some day with Buchdahl's Introduction to Hamiltonian Optics as a similar certificate of qualification.Hamiltonian theory describes with powerful generality the overall properties of optical systems considered as ‘black boxes’, although it does not describe the detailed structure needed to construct the systems and achieve these properties. Buchdahl's book is therefore on the subject of geometrical optics, but it is not about how to design lenses. It is, however a compact comprehensive account of the fundamentals of the theory written with the lens designer's needs very much in mind. Every lens designer worth his salt has at some time in his career attempted to apply the broad concepts of Hamiltonian optics to the solutions of practical problems. Success has been sufficiently rare that the theory, as such, has made little direct contribution to techniques for optical instrument design. The failures have been frustrating because of the obvious fundamental power of the theory and because of its conceptual elegance. The indirect effects have been large, however, both in contributing to an understanding of fundamental principles that govern the overall behavior of optical systems and in pointing the way to other, more practical, theoretical approaches.Buchdahl approaches the subject not only as a capable mathematical physicist, but as one who with a knowledge of practical optics has made a significant contribution to geometrical optical theory. Buchdahl's approach has, over the last decade, had a major impact on modern lens design with computers. Thus, he brings to this exposition of Hamiltonian optics a familiarity with practical optics not usually found in authors on this subject.The author claims his book to be non-mathematical, and indeed it might be so viewed by a professional mathematician. From the point of view of many physicists and engineers, it will appear to be quite mathematical. Moreover, this is a tightly written book. The subject matter is developed with precision, and the author expects the reader, at very point, to be master of the preceding exposition.4. Hamiltonian theory met with failures as a result of ______.A. newer finding related to the wave particle nature of lightB. very complicated concepts too difficult to understand by most lens designersC. too much mathematical detail in the theoryD. not enough practical information offered by the theory to allow for use by lens crafters5. The author of this passage implies that Introduction to Hamiltonian Optics is necessary to ______.A. the students who are major in mathematical geometryB. those who want to grasp the basic principles of optical systemsC. the lens designers who look for instructions on practical designsD. those who are interested in physics6. The article points out that the great benefits of Hamiltonian optics have been found is ______.A. indirect ways of learning mathematicsB. a fundamental power within the theoryC. the conceptual elegance of the theoryD. the practical applications of the theory in finding new approaches to old problems7. This passage is probably excerpted from ______.A. a review of a bookB. a chemistry textbookC. an optician's essayD. a general science textCIn 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. InArendt'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.DHardware in general,and smartphones in particular,have become a huge environmental and health problem in the Global South's landfill sites(垃圾填埋场).Electronic waste(e-waste) currently takes up 5 percent of all global waste,and it is set to increase rapidly as more of us own more than one smartphone,laptop and power bank They end up in places like Agbogbloshie on theoutskirts of Ghana's capital,Accra. It is the biggest e-waste dump in the world,where 10,000 informal workers walk through tons of abandoned goods as part of an informal recycling process.They risk their health searching for the precious metals that are found in abandoned smartphones.But Agbogbloshie should not exist.The Basel Convention,a 1989 treaty,aims to prevent developed nationsfrom unauthorized dumping of e-waste in less developed countries.The e-waste industry,however,circumventsregulations by exporting e-waste labelled as "secondhand goods' to poor countries like Ghana,knowing full well hat it is heading for a landfill site.A recent report found Agbogbloshie contained some of the most dangerous chemicals.This is not surprising: smartphones contain chemicals like mercury（水银）,lead and even arsenic(砷).Reportedly, one egg from a free-range chicken in Agbogbloshie contained a certainchemical which can cause cancer and damage the immune system at a level that's about 220 times greater than a limit set by the European Food Safety Authority(EFSA).Most worryingly,these poisonous chemicals are free to pollute the broader soil and water system.This should concern us all, since some ofGhana's top exports are cocoa and nuts.Some governments have started to take responsibility for their consumers' waste.For example,Germanyhas started a project that includes a sustainable recycling system at Agbogbloshie,along with a health clinic for workers.However,governments cannot solve the problem alone, as there is an almost limitless consumer demand for hardware,especially when governments' green policies are focused on issues like climate change.Only the manufacturers can fix this.A more economically sustainable and politically possible solution is through encouraging hardware manufacturers to make the repair, reuse and recycling of hardware profitable,or at least cost-neutral12. What can we infer from Paragraph 2?A. Electronic waste requires more landfill sites acrossGhana.B. Electronic waste is too complex to get fully recycleC. Electronic products need to be improved urgentlyD. Electronic pollution is a burning question in Agbogbloshie13. What does the underlined word "circumvents"in Paragraph 3 mean?A. AbolishesB. TightensC. Brings inD. Gets around14. What should be the best concern according to the text?A. The thread of polluted food around the worldB. The damage of chicken’s immune systemC. The lack of diversity inGhana's exportsD. The violation of EFSA's standards15. What does the author think is the best solution to the e-waste problem?A. Manufacturers' developing a sustainable hardware economyB. Governments’ adjusting their green policies about e-waste.C. Reducing customers' demands for electronic productsD. Manufacturers’ urging the government to make effective policies to ensure more profit.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。

2021届西安市长安区第一中学高三英语模拟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AThe last thing Caitlin Hipp would have expected as she prepared to turn 28 years old was to be living at homewith her parents. But through working as a part-time skating instructor and restaurant server, she isn't able to earn enough to live anywhere other than home.To some degree, multigenerational households have always been a part of American life. However, the number of young adults who have been moving back in with their parents — or never leaving home in the first place — has been growing steadily.UBS Financial Services released a report that even suggests one reason for the growing number of young adultsstill living at home could be that their family doesn't want them to leave.The report shows that 74 percent of millennials (千禧一代)get some kind of financial support from their parents after college. It finds that millennials have redefined the ties that connect parents and children. Millennials see their parents as peers,friends and instructors. Nearly three quarters talked with their parents more than once a week during college. In return, their parents happily provide financial support well into adulthood, helping fund everything for them.Stuart Hoffman, chief economist for the PNC Financial Services Group in theUS, said the number of young adults striking out on their own fell during the Great Recession. Although job growth for millennials since 2014 has improved, that doesn't necessarily mean that millennials are starting to fly the nest. He said, “They may like living at home and being able to save money.“ There's no doubt it has held back household formation and purchases of things people spend money on related to household formation and perhaps related to child-raising," Hoffman explained. "But they are probably traveling more and eating out more if they don't have a house expense or marriage. I don't know if it represents a change in moral values. But it's much more common for adult children to live in their parents’ homes because it's becoming part of the culture.1. What can we learn from the UBS Financial Services' report?A. Millennials are on good terms with their parents.B. Millennials are financially independent after college.C. Parents are unwilling to give their young adults allowance.D. Parents want their kids to stay with them forever.2. What does Hoffman think of young adults' living at home?A. It increases the consumption of household products.B. It may continue despite job growth.C. It is a sign of shift in moral values.D. It is new in American culture.3. What is the author's purpose of writing this passage?A. To introduce millennials' living habits.B. To stress the importance of financial independence.C. To explain why American young adults still live at home.D. To inform people of a social trend in theUS.BThe measurable threat to the environment has been worsened by the spread of COVID-19 that increases the need for plastic protective equipment. Most plastic is made from fossil fuels. Millions of tons of greenhouse gas are released from the development of these resources and plastic production and burning.The end life of plastic is just worrisome. Less than 10% of the plastic produced has been recycled. Even more of it has been burned. But the vast majority of plastic has been buried inland, and it is increasingly polluting the environment. We hear mostly about ocean plastic and the harm done to sea creatures that mistake plastic bags and bits for food. But microplastic is even more worrisome. Plastic doesn't break down biologically but instead breaks down into tiny particles（a very small piece of something）, which have been found in every corner of the planet, on land and in the air, in drinking water and food sources.Yet the public has not given this global environmental disaster the attention it requires. Instead, they have viewed single-use plastic—which makes up about 40% of plastic used each year—as a litter issue that can be solved through better recycling and waste management. That attitude must change because the recent global breakdown of the market for recycling has made it clear that it has never been, nor ever will be, able to keep up with plastic trash use.California has been the forerunner of plastic waste reduction—it was the first state to ban single-use plastic bags and may be the first state to transform the way goods are packaged. The state also came close to passing an act which would have required that products sold in plastic packaging in the state have a proven recycling rate of75% by 2032. California, though influential, can't solve this crisis alone. The US has long been producing a great amount of plastic trash and it should engage in reducing the use of plastic as well.4. Why does the author mention the release of greenhouse gas in paragraph 1?A. To show the harm of plasticB. To warn of the climate change.C. To call for the development of fossil fuels.D. To highlight the importance of plastic equipment.5. What's the author's attitude towards the public opinion on single-use plastic?A. Favorable.B. Tolerant.C. Curious.D. Opposed.6. What's California's role in reducing plastic waste?A. A pioneer.B. A failure.C. An objector.D. A predictor.7. What can be the best title for the text?A. Microplastic Products Are HarmfulB. Waste Recycling Is an Urgent MatterC. Plastic Waste Pollution Is a Wake-up CallD. Global Environmental Disasters Are IncreasingCI don’t want to talk about being a woman scientistagain. There was a time in my life when people asked constantly for stories about what it’s like to work in a field dominated (controlled) by men. I was never very good at telling those stories because truthfully I never found them interesting. What I do find interesting is the origin of the universe, the shape of space, time and the nature of black holes.At 19, when I began studying astrophysics (天体物理学), it did not bother me in the least to be the only woman in the classroom. But while earning my Ph.D. at MIT and then as a post-doctor doing space research, the issue started to bother me. My every achievement — jobs, research papers, awards — was viewed through the lens (镜片) of gender (性别) politics. So were my failures. Sometimes, when I was pushed into an argument on left brain versus (相对于) right brain, or nature versus nurture (培育), I would instantly fight fiercely on my behalf and all womankind.Then one day a few years ago, out of my mouth came a sentence that would eventually become my reply toany and all provocations (挑衅): I don’t talk about that anymore. It took me 10 years to get back the confidence I had at 19 and to realize that I didn’t want to deal with gender issues. Why should curing sexism be yet another terrible burden on every female scientist? After all, I don’t study sociology or political theory.Today I research and teach at Barnard, a women’s college in New York City. Recently, someone asked me how many of the 45 students in my class were women. You cannot imagine my satisfaction at being able to answer, 45.I know some of my students worry how they will manage their scientific research and a desire for children. And I don’t dismiss those concerns. Still, I don’t tell them “war” stories. Instead, I have given them this: the visual of their physics professor heavily pregnant doing physics experiments. And in turn they have given me the image of 45 women driven by a love of science. And that’s a sight worth talking about.8. Why doesn’t the author want to talk about being a woman scientist again?A. She is fed up with the issue of gender discrimination (歧视).B. She feels unhappy working in male-dominated fields.C. She is not good at telling stories of the kind.D. She finds space research more important.9. From Paragraph 2, we can infer that people would attribute (把……归因于) the author’s failures to ________.A. the burden she bears in a male-dominated societyB. her involvement in gender politicsC. her over-confidence as a female astrophysicistD. the very fact that she is a woman10. What did the author constantly fight against while doing her Ph.D. and post-doctoral research?A. Lack of confidence in succeeding in space science.B. Unfair accusations from both inside and outside her circle.C. People’s fixed attitude toward female scientists.D. Widespread misconceptions about nature and nurtured.11. What does the image the author presents to her students suggest?A. Women students needn’t have the concerns of her generation.B. Women can balance a career in science and having a family.C. Women have more barriers on their way to academic success.D. Women now have fewer problems pursuing a science career.DDid you know people who live in different parts ofChinahave different habits and preferences? For example, people from southernChinaprefer to eat vegetables, while people from northChinalike to eat meat. According to a new study in a journal, gene variations (变异) might be responsible for these differences. Researchers fromChina’s BGI collected genetic information from 141,431 Chinese women, who came from 31 provinces and consisted of 36 ethnic minority groups.They found that natural selection has played an important role in the ways that people living in different regions of China have developed, affecting their food preferences, immunities (免疫力) to illness and physical features.A variation of the gene FADS2 is more commonly found in northern people. It helps people metabolize (新陈代谢) fatty acids, which suggests a diet that is rich in flesh. This is due to climate differences.Northern Chinais at a higher latitude. This weather is difficult to grow vegetables in. Therefore, northerners tend to eat more meat.The study also found differences in the immune systems of both groups. Most people in southernChinacarry the gene CR1, which protects against malaria. Malaria was once quite common in southernChina. In order to survive, the genes of people in the south evolved to fight against this disease. However, people in the south are also more sensitive to certain illnesses, as they lack the genes to stop them.Genes can also cause physical differences between northerners and southerners. Most northerners have the ABCC11 gene, which causes dry earwax, less body smell and fewer sweats. These physical differences are also more beneficial to living in cold environments. Southerners are less likely to have this gene, as it did not develop in their population.12. What did the new study focus on?A. Regions.B. Eating habits.C. Gene variations.D. Ethnic minority groups.13. What is the main function of the gene FADS2?A. It helps store fat.B. It helps digest meat.C. It helps gain weight.D. It helps treat an illness.14. According to the study, most northerners ________.A. sweat less frequentlyB. are immune to malariaC. prefer vegetables to meatD. are more sensitive to climates15. How many differences did the study find related to genes?A. Two.B. Three.C. Four.D. Five.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。

But other birds are wishing up, evolving some seriously impressive tricks to spot the cuckoo eggs.Cuckoos are often know asparasites, meaning that they hide their eggs in the nest of other species. To avoid detection, the cuckoos have evolved so that eggs seem reproduction of those of their preferred targets. If the host bird doesn’t notice the strange egg in its nest, the little cuckoo will actually take the entire nest for itself after it comes out, taking the other eggs on its back and dropping them out of the nest.To avoid this unpleasant fate for their young, the other birds have evolved a few smart ways to spot the fakes, which we’re only now beginning to fully understand. One of the most amazing finds is that birds have an extra colour-sensitive cell in their eyes, which makes them far more sensitive to ultraviolet wavelengths and allows them to see a far greater range of colours than humans can. This allows cautious birds to detect a fake egg which might be exactly the same to our eyes.Fascinatingly, we’re actually able to observe different bird species at very different points in their evolutionary war with the cuckoos. For instance, some cuckoos lay their eggs in the nests of the redstarts. Theblue eggs these cuckoos lay are practically alike to those of the redstarts, and yet they are still sometimes rejected. Compare that with cuckoos who target dunnocks. While those birds lay perfectly blue eggs, their cuckoo invaders just lay white eggs with brown irregular shaped spots. And yet dunnocks barely ever seem to notice the obvious trick.Biologists suspect these more easily fooled species like the dunnocks are on the same evolutionary path as the redstarts, but they have a long way to go until they evolve the same levels of suspicion. What’s remarkable is that the dunnocks fakes are so bad and the redstart ones so good, and yet cuckoos are still more successful with the former than the latter.It speaks to just how thoroughly a species’ behavior can be changed by the pressures of natural selection, or it might just be a bit of strategic cooperation on the part of the dunnocks. Biologists have suggested that these birds are willing to tolerate a parasite every so often because they don’t want to risk accidentally getting rid of one of their own eggs.4. This passage can be most likely found in a ________.A. science surveyB. nature magazineC. zoo advertisementD. travel journal5. What does the underlined word “parasite” in paragraph 2 most probably refer to?A. Animals that work together to raise young.B Small harmful animals such as worms or mice.C. Animals that can adapt to changing environments.D. Animals which live on or inside other host animals.6. Which of the following is TRUE about the dunnock according to the passage?A. It is colour-blind and therefore cannot identify foreign eggs in the nest.B. It can easily remove cuckoo eggs from the nest because fakes are so bad.C. It is a host bird that is more likely to raise a cuckoo chick than the redstart.D. It is unable to evolve and hence accepts cuckoo eggs that appear in the nest.7. Which of the following can be inferred from the passage?A. Dunnocks may eventually learn to recognise foreign eggs.B. Redstarts seem to be less suspicious compared to dunnocks.C. Cuckoo birds are good at taking responsibility for their own young.D. It is very easy for cuckoos to imitate the colouring of the dunnock’s egg.There are similarities and differences between high school life and college life.For one thing, there are several similarities between high school life and collegelife. First, the most important task in high school and college is both studying. Studying is the most important as a student. Second, we need a goal to fight for in both high school life and college life. To lead a meaningful life, we have to set up a goal to achieve.For another, there are also some differences between high school life and college life. First, our studying is also the biggest difference. In high school, we are required to follow our teachers' steps and finish theirassignmentsevery day. While in college, there are no teachers giving such detailed requirements to us and we can choose study or not according to our own willing. What and how to study totally depends on us. Therefore, the ability of self-control is very important in college life. Second, the flexibility (灵活性) of time is another difference. In high school, we have no much leisure except for our time of study. However, in college, we have much controlled by ourselves except the time of classes. And we have more time to do what we like. Finally, college lifeis much more various and richer. Besides study, we can attend many other activities, which make our college life more wonderful.In brief, there are both similarities and differences between high school life and college life. However, no matter we are in which period, we need to make full use of every day so that we will never feel regretful.8. Why do students need a goal to fight in high school and college?A. To enter a good college.B. To avoid living a meaningless life.C. To develop the ability of control.D. To meet their parents’ satisfaction.9. What does the underlined word “assignments” in paragraph 3 probably mean?A. Projects.B. Tasks.C. Goals.D. Dreams.10. Which is the correct structure of the passage?A. ①-②③-④B. ①②-③-④C. ①-②③④D.①②-③④11. Which of the following can be the best title for the text?A. College LifeB. High School LifeC. High School and CollegeD. High School Life and College LifeAfter 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 said12.

They may or may not read notice boards that share relevant information of the artworks or artists. Imagine, before being permitted to direct their eyeballs to the art on the walls, museum visitors were required to read a 15- or 20- page introduction to each piece or each artist. How many people would go to museums if that were the case?Yet this seems to be the expectation when it comes to reading classical literature. Classic novels typically come with 15- or 20- page introductions, which often include spoilers, assuming that readers do not come to classic books to discover, be absorbed in, and be surprised by the story world. Also, apparently, we mustn’t read classics alone, without experts guiding our experiences.However, classic literature is in a unique position to show us that we’re not alone in our pains and joys. By taking us out of our time, classic books free us to see beyond the set of beliefs we stick to and to connect human experiences that remain alive across time and place. What could be more grounding, more comforting, than seeing ourselves in the battles, longings, and pleasures that have played out across hundreds, thousands of years of human history? Our personal engagement is the first step of a longer journey of discovery that deepens our knowledge and understanding of ourselves and our world. We may, for example, feel for Hester Prynne from Nathaniel Hawthorne’s The Scarlet Letter though we despair of the world she lived in.While we’re letting go of things, let’s stop worrying about understanding everything. We can’t. It will be fun if we embrace curiosity, the pleasure of working out a mystery, and our common relationships as humans. We can feel, for example, the power of self-sacrifice in Charles Dickens’ A Tale of Two Cities even when we lack full understanding of the cultural references and language.24. Most museum goers ____.A. enjoy reading notice boardsB. lack professional art knowledgeC. understand the artworks wellD. share common interest in artworks25. What can the “spoilers” in paragraph 2 possibly be?A. Plots given away in advance.B. Readers’ expe ctations.C. Guiding experts.D. Story writers.26. What prevents readers enjoying reading classics?A. Showing curiosity about the writers.B. Letting go of things.C. Trying to understand everything.D. Working out mysteries.27. What message is mainly conveyed in the passage?A. We should find more fun from classics.B. Experts need to give readers better guidance.C. Reading classics is a personal exploration.D. Classic literature benefits readers a great deal.CNew research linked outdoor air pollution to an increased risk of diabetes (糖尿病) globally, according to a study from Washington University in St. Louis and the Veterans Affairs (V A) St. Louis Health Care System. The findings raised the possibility that reducing pollution might lead to a drop in diabetes cases.“Our research shows a significant link between air pollution and diabetes glo b ally,” said Ziyad Al-Aly, a professor at Washington University. “We found an increased risk, even at low levels of ai r pollution currently considered safe by the US Environmental Protection Agency (EPA) and the World Health Organization (WHO). This is important because many industry groups argue that current levels are too strict. Evidence shows that current levels are s till not sufficiently safe and need tightening.” The findings were published on June 29 in The Lancet Planetary Health.To evaluate outdoor air pollution, the researchers looked at small pieces of dust, smoke and liquid droplets. In diabetes, pollution was thought to reduce insulin (胰岛素) production and prevent the body from changing blood glucose (葡萄糖) into energy that the body needed to maintain health.The researchers also found that poverty-stricken countries faced a higher diabetes-pollution risk including Afghanistan, Papua New Guinea and Guyana, while richer countries such as France, Finland and Iceland experienced a lower risk. The US experienced a middle risk of pollution-related diabetes.In the US, the EPA’s pollution limit was 12 microgra ms per cubic meter of air, the highest level of air pollution considered safe for the public, as was set by the Clean Air Act of 1990 and was updated in 2012. However, using mathematical models, Al-Aly’s team set an increased diabetes risk at 2.4 microgram s per cubic meter of air. Based on V A data, among a sample of citizens exposed to pollution at a level of between 5 to 10 micrograms per cubic meter of air, about 21 percent developed diabetes.“The team in St. Louis is doing important research to firm up links between pollution and health conditions such as diabetes,” said commission member Philip J. Landrigan, MD, a pediatrician and epidemiologist at Mount Sinai School of Medicine in New York. “I believe their research will have a significant global effect.”28. What can we know from the first two paragraphs?A. Diabetes had little to do with outdoor air pollution.B. Reducing pollution might lead to a lot of diabetes cases.C. Air pollution contributed significantly to diabetes globally.D. Low-level air pollution was always considered safe by WHO.29. How did the researchers assess the air pollution?A. By reducing insulin production.B. By analyzing small matter in the air.C. By connecting diabetes and pollution.D. By checking blood glucose in the body.30. Why does the author list some figures in paragraph 5?A. To present a result.B. To support his idea.C. To make a comparison.D. To draw a conclusion.第二节：任务型阅读（共5小题；每小题2分，满分10分）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。
