Make sure you do it.★Try at least one kind of team sportsBeing a good team player is an important skill in life. You can’t just think of yourself, but have to work well with other people.

Teams usually have a good social life too—you’ll go to lots of parties and make many friends.★Collect somethingOne of the best hobbies for under-18s is collecting things. You could collect kinds of stamps, or you could collect things that make you remember what you have done, like cinema tickets for films you have seen or letters from friends.

The National Park Service was formed 44 years later in 1916.Yellowstone, which is mostly in the state of Wyoming, is considered an example of the success of the National Park System.Humans have been present in Yellowstone for more than 11,000 years.Yellowstone contains beautiful mountains, deep canyons(峡谷), lakes and rivers.The nameYellowstonecomes from the river running through the area. At first known as Rock Yellow River, it became known as theYellowstoneRiver.Yellowstoneis host to many different species of plants. However, the park is most distinctive because of what lies underneath it. It sits on top of an ancient super volcano, known as The Yellowstone Caldera. The caldera is 48 by 72 kilometers. And it remains an active volcano.It is believed that the last time the volcano erupted was one half million years ago. The area has had three major eruptions in the last three million years.Experts say it may erupt again in another 1,000 to 10,000 years. But each year, there are thousands of earthquakes atYellowstone. Most are too small to be felt by people visiting the park.Yellowstoneis filled with the beauty of many hot water springs. hot water and gasses are trapped under the earth. they rush to the surface in the form of hot water and steam.Old Faithful is The most famous one .Iterupts about every hour or hour and a half. The eruption can last from one and a half minutes up to 5 minutes. The amount of hot water it expels（排出）in that time can be as much as 31,000 liters or more.In addition to its beauty and wonder, Yellowstone is an animal sanctuary（保护区）. It is home to the largest group of wild animals in theUnited States. As you travel through the park, you can sometimes see them in their natural habitat and hear their calls .4. What wasYellowstonenamed after?A. RockYellow RiverB. The amazing mountains.C. The stones with yellow color1D. The first discovery inwyoming.5. What makesYellowstonequite unique?A. The scenery is beautiful.B. There are a lot of explorers.C. It’s home to many plants.D. Its location is very special.6. What does the underlined word“It”in Paragraph 5 refer to?A. The earth.B. Yellowstone.C.Old Faithful.D. TheYellowstoneCaldera.7. What can we infer from the text?A. The Yellowstone Caldera has been dead for years.B. Yellowstone is a shelter for the protected wildlife.C. Big earthquakes happen frequently atYellowstone.D.YellowstoneNational Parkhas attracted visitors for centuries.CNot long after the first fitness magazine was published, a list probably followed soon after, ranking the best fitness equipment. This tradition has continued, with the implied message: usethisand exercise willbe yours.And that's part of the problem, says Dr. Lieberman, a professor of Harvard University. There isn't one “best” anything to achieve fitness. Besides, people understand exercise is good for them. Knowledge about exercise still doesn't motivate.Before you can answer why, it helps to look at history. Before the Industrial Revolution, people fetched water and walked up stairs because they had to. But then technology made life and work easier. Exercise has become something that people have to carve out time for. “It's a fundamental instinct to avoid physical activity when it's neither necessary nor rewarding,” he says.It would seem like being healthy would qualify as necessary, but a doctor's prescription to exercise “can make it like taking cod liver oil,” Lieberman says. “Sometimes it works, but more often than not, it doesn't. And it's still coming across as an order, and “not having a heart attack in five years is not an immediate reward,” says Dr. Beth Frates, assistant professor at Harvard Medical School.People might not want to exercise because it's never been enjoyable. Most of us probably have memories of gym class, not being picked for a team, or being in a fitness center that's filled with in-shape people. The majority don't feel excited. They feel that exercise isn't for them, but it can be. Coaching people in an empowering and motivating way can work much better than ordering someone to exercise. It starts with an expanded definition of what counts as exercise, and an injection of what's rarely used to describe exercise, but is certainly allowed: namely, fun.8. What does the underlined “this” in paragraph 1 refer to?A. The magazine.B. The tradition.C. The equipment.D. The message.9. What can we infer about technology?A. It improves life quality.B. It saves people's time.C. It drives social progress.D. It makes exercise less likely.10. Why does the author mention “cod liver oil” in paragraph 4?A. To attach importance to health.B. To present a doctor's prescription.C. To explain exercise is considered inessential.D. To introduce the latest medical application.11. What is the main idea of the last paragraph?A. Exercise should be made more joyful.B. It's more fun to work out with others.C. We may encounter bad workout experiences.D. Orders work well to motivate people to exercise.DIn May this year, as part of our 150th anniversary, we asked readers aged between18 and 25 to enter an essay competition. The task was to tell us, in no more than 1,000 words, what scientific advance they would most like to see in their lifetimes, and why it mattered to them.The response was phenomenal: we received 661 entries. Some entrants hoped that science would make their lifetimes much longer than they can currently expect. Many looked forward to work that will end climate change. Others wanted to see advances in our understanding of human history, crop growth, space exploration, and medical technologies. The ideas were inspiring.The winner is a compelling essay by Yasmin Ali, a PhD student at the University of Nottingham, UK. Ali submitted a piece on Beethoven, her brother’s hearing loss and the science which she hoped would one day cure it. It stood out to the judges as a reminder of why many scientists do research: to make the world better tomorrow than it is today.All essays were judged by a group of Nature editors. The top ten submissions were then ranked by three members of a separate judging group: Magdalena Skipper, editor-in-chief of Nature; Faith Osier, a researcher; and Jess Wade, a physicist. All submissions were kept anonymous throughout the process.We also selected two runners-up(非冠军的获奖者).Physicist Robert Schittkoat Harvard University in Cambridge, Massachusetts, proposes that nuclear fusion(核聚变) could offer a solution to the climate crisis, in a piece that effortlessly mixes grand ambition with gentle humour. And chemist Matthew Zajac at the University of Chicagoin Illinois wrote a powerful personal account of why he wants to see advances in the field of same-sex reproduction.The results show that today’s young scientists have a wealth of ideas, talent and conviction that research can transform their world. We look forward to seeing what they do next.12. What’s the essay competition about?A. The scientific expectation.B. The fantastic scientific ideas.C. The dreams of future life.D. The celebration of anniversary.13. Why Yasmin Ali was chosen the winner?A. She showed great talent in music.B. She found the cure for the loss of hearing.C. She appealed for people to care about hearing loss problem.D. She reminded people to remember the meaning of science development.14. What can we learn about the result of the essay competition?A. Robert Schittko won the second place.B. There were two winners in the essay competition.C. Matthew Zajac presented his view of same-sex reproduction.D. The two runners-up were selected for the same field they chose.15. What isthe author’s attitude to the competitors’ ideas about science expectations?A. Doubtful.B. Favorable.C. Impossible.D. Ignorant.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。

She had requested the community to turn it into a museum upon her death. On a sunny Saturday, Sally and I drove over to the museum. She asked, "Do you have the address? " "No, but I'll recognize it, there was a picture in the magazine.""Oh, stop. There it is!"The museum was free. We entered, excited. A group of people sitting in the hall stopped talking and stared at us."May I help you? " a man asked. "No, " I said. "We're fine." Tour guides got on my nerves. What if they talked a long time about a painting you weren't that interested in? Sally had gone upstairs. The people in the hall seemed very nosy（爱窥探的）, keeping their eyes on me with curiosity. What was their problem? I saw some nice sculptures in one room. Suddenly I sensed a man standing behind me. "Where do you think you are? " he asked. I turned sharply. "The Mckay Art Museum!" He smiled, shaking his head. "Sorry, the Mckay is on New Braunfels Street." "What's this place? " I asked, still confused. "Well,it's our home." My heart jolted（震颤）. I raced to the staircase and called out, "Sally! Come down immediately!""There's some really good stuff up there." She stepped down, looking confused. I pushed her toward the front door, waving at the family, saying, "Sorry, please forgive us, you have a really nice place." Outside, when I told Sally what happened, she covered her mouth, laughing. She couldn't believe how long they let us look around without saying anything.The real McKay was splendid, but we felt nervous the whole time we were there. Van Gogh, Picasso. This time, we stayed together, in case anything else unusual happened.Thirty years later, a woman approached me in a public place. "Excuse me, did you ever enter a residence, long ago, thinking it was the McKay Museum? ""Yes. But how do you know? We never told anyone.""That was my home. I was a teenager sitting in the hall. Before you came over, I never realized what a beautiful place I lived in. I never felt lucky before. You thought it was a museum. My feelings about my home changed after that. I've always wanted to thank you."(1) How did the author feel about being stared at by the people in the hall?A. Concerned.B. Frightened.C. Puzzled.D.

And every Sunday afternoon, neighborhood residents chopped their food waste firstly, waiting for Victor Ibarra and Sandy Norse's arrival to collect the staff.These household waste contains more whole apples, whole tomatoes, and whole bunches of cabbages than commercial waste does, while cat litter, bones, and disposable cups, bowls and plates are not accepted.In 2016, they even founded BK ROT, a nonprofit collecting and composting operation to continue their careers. At BK ROT, food waste is mixed with wood chips and sawdust（锯末）, then moved, over a period of weeks, through a series of wooden bins the size of washing machines. By the time it reaches the final bin, it's black and bug-covered and unrecognizable as former food. The resulting mass, the compost, is sold in local stores or directly to individuals. "Somebody came from Staten Island yesterday and took a lot, " Norse said, "but most of it goes to nearby urban farms and community gardens."Some farmers and many citizens follow their examples, beginning to turn to running their farms and gardens without using any chemicals. To their delight, they feel that this makes the soil in their fields richer in minerals and so more fertile. BK Rot is becoming popular with a goal—to grow good food and avoid damaging the environment or people's health.(1) How is the compost made fromA. First combined with sawdust, moved and then rots.B.

2019-2020学年嘉兴市第一中学高三英语二模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AOur Teen Summer Spanish Program is two weeks of fun, educational excitement that helps students learn Spanish fast. Our Spanish summer program allows our students to learn from highly trained, certified teachers and be absorbed in the language and theculture of Costa Rica.Features include:* Intensive(强化的) daily Spanish classes* Extracurricular classes in dance, cooking, music, and handiwork* Outdoor activities including hiking, camping, rafting, and ziplining(高空滑索)* Homestay with a local Costa Rican family* Volunteer work in needy neighborhoodsOur Teaching Methods:We are proud to use TPRS---Total Physical Response Storytelling---in our curriculum. This innovative method uses strange and amusing stories to teach new vocabulary, increase fluency, and get students involved by giving them the opportunity to alter the details themselves. Because of the silliness, creativity, and repetition involved, TPRS allows students to learn easily and remember information effortlesslyMemorizing vocabulary and listening to lectures on grammar are slow, inefficient ways to learn a new language. The best way to truly learn and commit new material to memory is through conversation. In our Spanish classes, students can expect to speak up to 80% of each class. By speaking in the new language freely and consistently, students can see progress faster because they are using the new grammar and vocabulary that they have learned at the same time. This helps the brain remember the new words and grammar structures for future use, making it much easier to progress.1.What does the program do?A.It offers weekly Spanish classesB.It focuses more on outdoor activitiesC.It gives teachers a chance to receive trainingD.It provides activities about the Spanish culture2.What is the best way to learn a language according to the text?A.Memorizing a larger vocabularyB.Speaking more in the new language.C.Mastering more grammar structuresD.Writing stories to share with others3.What is the purpose of the text?A.To employexperienced Spanish teacherB.To hire foreign volunteers for a programC.To attract teen foreigners to a programD.To introduce language learning methodsBWhether for a special holiday, as a way of showing gratitude or just a way of letting someone know you care, gift giving is a universal custom Though the purpose may be similar from place to place, traditions vary widely from one country to the next. A behavior that shows respect in one place might be consideredoffensivesomewhere else. Take a look at unique gifting traditions from around the world.Here in theUS, a set of kitchen knives seems like the perfect gift idea for a wedding. However, in certain European countries likeGermany, people believe that a knife presented as a gift will cut off your friendship. There is a way to break it: Tie a coin to the knife or gift box. The receiver then returns the coin to you as a “payment”to remove the bad luck.There's a well-known Italian wedding tradition where the groom's (新郎) tie is cut into a number of tiny pieces. Wedding guests can then "buy” these tie pieces in exchange for cash. It's a fun way to give money to the new couple thatleaves guests with a wedding souvenir.As left hands are considered unclean in Indian culture, behaviors such as touching, passing money, or giving gifts are to be done with the right hand. Different from some other cultures , an odd number (奇数) of thingsor currency represents good luck. For example, £11 should be given rather than £10.InZimbabwe, it is common to directly ask for a gift. When you receive a gift without asking for it, even if the giver's family is poor, it's the worst way to reject the offering. Also, expressing thanks with actions is better than giving thanks orally (口头地).These may include jumping up and down, dancing, or whistling.4. What does the underlined word “offensive“ in paragraph 1 refer to?A. Rude.B. Creative.C. Suitable.D. Caring.5. How do people prevent friendship breaking down when giving gifts like knives?A. The guests cut the groom's tie into pieces.B. The receiver returns the coin to the giver.C. The giver gives gifts with the right hand.D. The receiver expresses thanks by dancing.6. What can we learn about the gift giving inZimbabwe?A. It is not proper to ask for a gift directly.B. It's better to reject a gift from a poor family.C. One can express thanks by writing letters.D. Showing gratitude with actions is better than words.7. Which can be a suitable title for the text?A. The Wayof Showing GratitudeB. A Fun Behavior to Respect PeopleC. Various Gift Giving TraditionsD. A Special Custom of Gift GivingCThe World Wildlife Fund (WWF) says more than half of the world’s wildlife population has been lost, whichthe conservation group says has placed the health of the planet at risk.The WWF recently released its 10th Flagship Living Planet Report. The group warns the condition of the world's animals is worse than its earlier reports showed, indicating worldwide action is needed.The WWF is worried about the loss of and damage to Earth’s environment. The report provides information about more than 10,000 animal populations from 1970 to 2010. These populations are called “vertebrate species,” or animals with backbones — like fish, birds, mammals, amphibians and reptiles. The report shows these populations have dropped by 52 percent in just 40 years. It warns freshwater species have fallen by 76 percent, which is almost twice the loss of land and ocean species. Most of these losses are in the tropics, with the biggest drop inLatin America.Marco Lambertini, the WWF’s International Director-General said, “This is about losing natural habitats. This is aboutconvertingforests, grasslands, and wetlands into agriculture mainly, and it is about unsustainable use of wildlife. Illegal hunting has been actually increasing over the last 10 years, which definitely a driving force forextinction, particularly of large species.”The report also notes what it calls the world’s “Ecological Footprint”, that is, the effect of human activities on the planet. Mr. Lambertini says there has been an increase in carbon dioxide gases and the pouring of nitrogen into oceans and rivers from fertilizers used in agriculture, which certainly cannot continue.“We are consuming on average every year about the equivalent of about 1.5, one and a half times the resources available to the planet. That means we are cutting trees more quickly than they can be restored. We are fishing the oceans more quickly than fishing stocks can reproduce, and we are emitting in the atmosphere more CO2than the natural systems can actually absorb, which is clearly not sustainable.”Mr. Lambertini warns climate change affects almost everyone on the planet and that whole species may disappear if the world does not reduce the effects of humans on the climate.8. According to the passage, what kind of species faces the biggest drop in population?A. Land and ocean species.B. Animals with backbones.C. Freshwater species inLatin America.D. Freshwater species in the tropics.9. All the following can contribute to the loss of world’s wildlife population EXCEPT ________.A. turning wildlife habitats into agriculture land.B. making sustainable use of wildlife.C. hunting illegally.D. emitting CO2 gases and pouring nitrogen.10. Which does the underlined word “converting” in paragraph 4 mean?A. Conserving.B. Conveying.C. Exchanging.D. Transforming.11. It can be inferred from the passage that _______.A. Marco is much concerned about human’s current behaviors towards wildlife.B. what the planet provides now can satisfy human’s sustainable development.C. more than half of the world’s wildlife population has been lost.D. if humans reduce the effects on the climate, the whole species will not disappear.DElizabeth Spelke, a cognitive psychologist at Harvard, has spent her career testing the world’s most complexlearning system-the mind of a baby. Babies might seem like no match for artificial intelligence (AI). They are terrible at labeling images, hopeless at mining text, and awful at video games. Then again, babies can do things beyond the reach of any AI. By just a few months old, they’ve begun to grasp the foundations of language, such as grammar. They’ve started to understand how to adapt to unfamiliar situations.Yet even experts like Spelke don’t understand precisely how babies or adults learn. Consider one of the most impressive examples of AI, Alpha Zero, a programme that plays board games with superhuman skill. After playing thousands of games against itself at a super speed, and learning from winning positions, Alpha Zero independently discovered several famous chess strategies and even invented new ones. It certainly seems like a machineeclipsinghuman cognitive abilities. But Alpha Zero needs to play millions more games than a person during practice to learn a game. Most importantly, it cannot take what it has learned from the game and apply it to another area.To some AI experts, that calls for a new approach. In a November research paper, Francois Chollet, a well-known AI engineer, argued that it’s misguided to measure machine intelligence just according to its skills at specific tasks. “Humans don’t start out with skills; they start out with a broad ability to acquire new skills,” he says. “What a strong human chess player is demonstrating is not only the ability to play chess, but the potential to fulfill any task of a similar difficulty.”12. Compared to an advanced AI programme, a baby might be better at ________.A playing games B. identifying locations C. labeling pictures D. making adjustments13. What does the underlined word “eclipsing” in Paragraph 3 probably mean?A. Imitating.B. Beating.C. Limiting.D. Promoting.14. According to the text, Francois Chollet may agree that ________.A. AI is good at completing certain assignments.B. AI is likely to gain abilities with less training.C. AI lacks the ability of acquiring specific skills.D. AI performs better than humans in cognitive ability.15. Whichwould be the best title for this passage?A. What is exactly intelligence?B. Why is modern AI advanced?C. Where is human intelligence going?D. How do humans face the challenge of AI?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。

2019-2020学年嘉兴市实验高级中学高三英语二模试卷及答案解析
2019-2020学年嘉兴市实验高级中学高三英语二模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ADuring ancient times, children didn’t have smartphones, iPad or computers to entertain themselves. Instead, they came up with interesting games to play.★Stone ballsDuring the Qing Dynasty, kicking a stone ball around was a popular sport in the northern part of China, and it was often played in the winter to protect kids from the cold. Stones were carved into small balls and kicked along with feet. In 1999, the sport was included in the 6th National Ethnic Group Traditional Sports Meeting held in Beijing.★Flying kitesKites have quite a long history. The earliest kites were made of wood, instead of paper. Nowadays, the four most famous kites are the Beijing kite, Tianjin kite , Weifang kite and Nantong kite, of which each has distinctive features. The kite which resembles a swallow is a well-known Beijing style.★Hide-and-seekHide-and-seek is a traditional game for children, popular around the nation. There are two ways to play: covering a child’s eyes while other kids run around to tease(戏弄) him or, more commonly, participants hide and one child must try to find them.★Playing diabolosA diabolo is always made of wood or bamboo and has empty space in the center. By juggling(边抛边接) the diabolo on the rope, the high-speed spinning diabolos will make a sound like a whistle. Playing diabolos is an interesting folk game, especially popular in North China. Playing diabolos was also included in the first group of national intangible cultural heritage(非物质文化遗产).1.Why did ancient children often play stone balls in the winter?A.To practice their feet.B.To warm themselves.C.To train their skills.D.To relax themselves.2.Which kites are swallow-shaped?A.Weifang kites.B.Tianjin kites.C.Beijing kites.D.Nantong kites.3.Why does playing diabolos make a sound?A.Because the diabolo’s center is empty.B.Because the high-speed spinning diabolo is light.C.Because the diabolo is equipped with a whistle.D.Because ropes’ surface moves against the diabolo’s.BWho is a genius? This question has greatly interested humankind for centuries.Let's state clearly: Einstein was a genius. His face is almost the international symbol for genius. But we want to go beyond one man and explore the nature of genius itself. Why is it that some people are so much more intelligent or creative than the rest of us? And who are they?In the sciences and arts, those praised as geniuses were most often white men, of European origin. Perhaps this is not a surprise. It's said that history is written by the victors, and those victors set the standards for admission to the genius club. When contributions were made by geniuses outside the club—women, or people of a different color1 or belief—they were unacknowledged and rejected by others.A study recently published bySciencefound that as young as age six, girls are less likely than boys to say that members of their gender(性别)are “really, really smart.” Even worse, the study found that girls act on that belief: Around age six they start to avoid activities said to be for children who are “really, really smart.” Can our planet afford to have any great thinkers become discouraged and give up? It doesn't take a genius to know the answer: ly not.Here's the good news. In a wired world with constant global communication, we're all positioned to see flashes of genius wherever they appear. And the more we look, the more we will see that social factors(因素)like gender, race, and class do not determine the appearance of genius. As a writer says, future geniuses come from those with “intelligence, creativity, perseverance(毅力), and simple good fortune, who are able to change the world.”4. Whatdoes the author think of victors' standards for joining the genius club?A. They're unfair.B. They're conservative.C. They're objective.D. They're strict.5. What can we infer about girls from the study inScience?A. They think themselves smart.B. They look up to great thinkers.C. They see gender differences earlier than boys.D. They are likely to be influenced by social beliefs6. Why are more geniuses known to the public?A. Improved global communication.B. Less discrimination against women.C.Acceptance of victors' concepts.D. Changes in people's social positions.7. What is the best title for the text?A. Geniuses Think AlikeB. Genius Takes Many FormsC. Genius and IntelligenceD. Genius and LuckCFor years video games have been criticised for making people more antisocial, overweight or depressed. Bui now researchers are finding that video games can actually change us for the better and improve both our body and mind.Games can help to develop physical skills. Pre-school children who played interactive games have been shown to have improved motor skills, for example they can kick, catch and throw a ball better than children who don’t play video games. A study found that those who played video games were 27 percent faster and made 37 percent fewer errors than those who didn't.Games also benefit a variety of brain functions, including decision-making. People who play action-based games make decisions 25 percent faster than others, according to one study. It was also found that the best gamers can make choices and act on them up to six times a second, four times faster than most people. In another study by researchers from the University of Rochester in New York, experienced gamers were shown to be able to pay attention to more than six things at once without getting confused, compared with the four that most people can normally keep in mind.There is also evidence that gaming can help with psychological problems. At the University of Auckland in New Zealand, researchers asked 94 young people diagnosed with depression to play a 3D fantasy game called SPARX and in many cases, the game reduced symptoms of depression more than conventional treatment.8. In what way playing video games benefits very young children?A. Muscle control.B. Social interaction.C. Decision-making.D. The ability to focus.9. Which type of video game improves the decision-making speed?A. Interactive games.B. Action-based games.C. 3D fantasy games.D. Violent games.10. What is the authors attitude to video games?A. Indifferent.B. Objective.C. Worried.D. Critical.11. What is the text mainly about?A. The effects of different types of video games.B. The negative effects of playing video games.C. The beneficial effects of playing video games.D. The effects of games on people's behavior.DRecently, I experienced a wonderful lesson in how little things still meana lot. My brother, mother and I live in Hawaii. Our farm is at least a dozen miles from even the most basic of services. Therefore, I take weekly trips to the shop to gel supplies. About a month ago, I finished loading up the car and was about to leave when a piece of paper on the ground caught my eye. I picked it up and read it carefully.Immediately, I was grateful that I had done that___4___It was a receipt (收据) from the State Motor Vehicle Division, recording the owner's payment of her Vehicle's Registration fees. I put myself in his or her shoes and thought: no one would throw this away. I looked over the receipt for any personal data, perhaps a license plate (车牌) or telephone number, but failed. How could I find the owner in the busy, crowded parking lot? Had it been lying there for a few minutes or a week? So I checked the date, the fees paid and the name of the owner, who must live in our town. I decided that the best and easiest step to take was to put the receipt in an envelope and send it to the owner first the next morning.By the end of the week, I received a beautiful “thank you” letter from a woman including a handwritten message and a card. In the letter, the woman explained how the wind took her receipt from a pocket in her car's passenger door. She had searched everywhere for quite some time before giving up.It felt great to know I had helped someone avoid a loss by doing something that seemed little and unimportant.12. What does the underlined sentence in paragraph 1 mean?A. He was lucky to learn the lesson.B. It was a good idea to do shopping that day.C. He was right to pick up the paper.D. It turned out the paper belonged to the writer.13. What information did the writer get from the paper?A The woman's license plate number.B. The woman's phone number.C. The woman's name.D. The woman's address.14. How did the woman lose the receipt?A. She forgot where she had put it.B. A strong wind blew it away.C. It fell onto the floor.D. She left it in the parking lot.15. What can be the best title for the text?A. A Lesson I Will Never ForgetB. Never Lose Heart or Give upC. Little Things Still Mean a LotD. Think Carefully Before You Act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。
2019-2020学年嘉兴市嘉善第二高级中学高三英语二模试题及答案
2019-2020学年嘉兴市嘉善第二高级中学高三英语二模试题及答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项AYou have to praise the smoothness（顺畅）of ants on the move. No matter how many of them are going toward a place, there's never a hold-up. A new research paper shows how ants keep traffic flowing by changing their behavior to meet changing conditions.For their experiments, researchers from the University of Toulouse focused on Argentine ants, animals that often move from colony（群落）to colony depending on where the food is. Making use of Argentine ants' talent for fast travel, the researchers built bridges connecting their colonies. The bridges were different in width from a fifth to three-quarters of an inch. The colonies, too, were of different sizes, ranging from 400 to more than 25,000 ants.Then the researchers sat back andmonitoredthe traffic. To their surprise, even when those narrower bridges were full of ants, there were no "traffic accidents". "When the number of ants on the bridge increased, ants seemed to be able to understand the situation and adjusted（调整）their speed accordingly to avoid making the traffic flow stop. "the authors note. "Moreover, ants avoided entering a busy road and made sure that the bridge was never too packed to cross.”The lesson for humans? The traffic problem may lie in our inability to adjust our driving habits for the good of the whole. Driving is fun when there are few cars on the road. Then the traffic moves very slowly. And yet, some impatient driver still acts like he's alone on the road.The research suggests that projects, like the ever-widening of highways, may never free us from traffic jams. As long as we drive along with our own habits, no matter how many other people are on the road, we'll always end up in a traffic jam. Indeed, less space may actually be a good thing. It leaves less room for individual choice and forces us to take a page from the driving book of ants.1. What is Paragraph 2 mainly about?A. The results of the experiments.B. The purpose of the experimentsC. The preparation of the experiments.D. The requirements of the experiments2. What does the underlined word "monitor" in paragraph 3 probably mean?A. watch and check.B. seek and improveC. design and planD. discuss and practise3. What is the best title for the text?A. Is widening highways a solution?B. Why don't ants need traffic lights?C. Can we learn safe driving from ants?D. What can ants teach us about traffic jams?BA team of engineers atHarvardUniversity in trying to create the first robotic fly. Designed to do what a fly does naturally, the tiny is the size of a fat housefly. Its mini wings allow it to stay in the air and perform controlled flight tasks."The added difficulty with a project like this is that actually none of its components is off the shelf and so we have to develop them all on our own’ said Robert Wood, a Harvard engineering professor.They engineered a series of systems to start and drive the robotic fly. “The seemingly simple system which just moves the wings hasa number of interdependencies (相互依赖）on the individual components, each of which individually has to perform well, but then has to be matched well to everything it d connected to,” said Wood.While this first robotic flyer is linked to a small, off-board power source, the goal is eventually to equip it with a built-in power source, so that it might someday perform data-gathering work at rescue sites，in farmers’ fields or on the battlefield. "Basically it should be able to take off, land and fly around，” he said.Wood says the design offers a new way to study flight mechanics and control at insect-scale. Yet, the power, sensing and computation technologies on board could have much broader applications.“You can start thinking about using them to answer open scientific questions, you know, to study biology in ways that would be difficult with the animal，but using these robots instead” he said. "So there are a lot of technologies and open interesting scientific questions that are really what drives us on a day-to-day basis.”4. What is the typical characteristic of the robotic fly?A. It's automatic.B.It's very small.C. It's controllable.D. It's quite powerful.5. We can infer from the passage that the robotic flyer can____ .A. act as a spy planeB. help do farm workC.fly at a very high speedD. answer many scientific questions6. What is Wood's idea about the robotic fly according to the last paragraph?A. It is highly questionable.B. It has wide practical applications.C. It gives scientists interest in flying machines.D. It points to a new direction in studying biology.7. What can be the best title for the passage?A. Harvand's Study in the Field of Insects.B. A Breakthrough in Engineering ScienceC. An Interesting Invention一Robotic FlyD. Robotic Fly一a Copy of Real Life InsectCIf you ever get the impression that your dog can "tell" whether you look delighted or annoyed, you may be onto something. Dogs may indeed be able to distinguish between happy and angry human faces, according to a new studyResearchers trained a group of 11 dogs to distinguish between images(图像)of the same person making either a happy or an angry face. During the training stage, each dog was shown only the upper half or the lower half of the person's face. The researchers then tested the dogs' ability to distinguish between human facial expressions by showing them the other half of the person's face on images totally different from the ones used in training. The researchers found that the dogs were able to pick the angry or happy face by touching a picture of it with their noses more often than one would expect by random chance.The study showed the animals had figured out how to apply what they learned about human faces during training to new faces in the testing stage. "We can rule out that the dogs simply distinguish between the pictures based on a simple cue, such as the sight of teeth," said study author Corsin Muller. "Instead, our results suggest that the successful dogs realized that a smiling mouth means the same thing as smiling eyes, and the same rule applies to an angry mouth having the same meaning as angry eyes.""With our study, we think we can now confidently conclude that at least some dogs can distinguish human facial expressions," Muller toldLive Science.At this point, it is not clear why dogs seem to be equipped with the ability to recognize different facial expressions in humans. "To us, the most likely explanation appears to be that the basis lies in their living with humans, which gives them a lot of exposure to human facial expressions and this exposure has provided them with many chances to learn to distinguish between them." Muller said.8. The new study focused on whether dogs can_________.A. distinguish shapesB. make sense of human facesC. feel happy or angryD. communicate with each other9. What can we learn about the study from paragraph 2?A. Researchers tested the dogs in random order.B. Diverse methods were adopted during training.C. Pictures used in the two stages were differentD. The dogs were photographed before the lest.10. What is the last paragraph mainly about?A. A suggestion for future studies.B. A possible reason for the study findings.C. A major limitation of the studyD. An explanation of the research method.11. In which section is the text most likely to be found in a newspaper ?A. EntertainmentB. EconomyC. ScienceD. NatureDHow much do consumers care about the carbon footprint of the products they buy? Would they care more if the goods were labeled with emissions（排放物）data?Does it matter at which stage in the lifecycle of a product the carbon is emitted? Research published in the International Journal of Environmental Policy and Decision Making offers a way to find out．Study participants view a carbon footprint label as similar to labels that have appeared on some existing products．The label shows the carbon dioxide emissions connected with their production, transportation, usage and disposal（清理）, thus showing the buyer the likely effect on climate change of buying a particular product．In the first group of studies, the research team proved that carbon emissions and a carbon emissions label would indeed play a role in consumer product decisions, although not as great a role as price．In a second set of studies, the team found that emissions connected with usage were most important to consumers followed by the transportation and disposal stages．The carbon footprint of the producing process was considered less important to consumers than the other stages in the product's lifecycle because it is outside the consumer's control．That is, the participants felt they were less responsible for carbon emitted during producing process．Consumers value recycling a product, but the researchers found that, overall, the consumers would preferproducers to offset（补偿）carbon emissions rather than having toaddressthe problem directly themselves．Consumers are increasingly concerned with climate change problems, and already carbon labeling is appearing on some products．"We find that participantsnot only take the carbon label into account when making product decisions, but they want detailed information on the label," the researchers explain．They suggest that companies should prepare for how carbon emissions labels might affect future consumer choice．12. Which of the following most affects consumer's choice?A. Labels．B. Price．C Packaging． D. Carbon footprint．13. About the carbon dioxide emissions in the product's lifecycle, which stage do consumers care most?A. Usage stage．B. Transportation stage．C. Disposal stage．D. Producing stage．14. Which of the following can best replace the underlined word "address"?A. Look into．B. Point out．C. Deal with．D. Run into．15. What can be inferred from the last paragraph?A. Companies should take carbonemissions more seriously．B. All products have been labeled with carbon emissions data．C. Producers will attach less importance to carbon emissions labels．D. Products labeled with carbon emissions data will have poor sales．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。

2019-2020学年嘉兴市秀洲现代实验学校高三英语二模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APersonal Time Off(PTO)is something my wife and I created after having kids. We learned that，over time，a full life can leave little time for personal rest and for reflection，hanging out with friends，or just being“off. ”So，after a number of years，we make a change. If I can persuade you to take your own PTO，then these might help.■Schedule itFirst of all，one of our favorite family sayings is“schedule it. ”Sounds easy enough，but life gets complicated managing full-time work and full-time family. Put yourPTO time on the calendar and you make it a real thing.■Be flexible and strictIf you can schedule PTO at the same time each week，then all the better. Because our calendar can get rather full，flexibility in scheduling becomes a necessity. But being strict in actually taking the time each week is more important. Skipping it once makes it easier to skip again.■Take enough timeMy typical PTO lasts a couple of hours or longer. Sometimes it might be half the day depending on what I’m doing. The goal is to spend enough time away to1et your shoulders drop.■Do what you want to doRemember，PTO time is about personal time to do what you want to do，not what you have to do. PTO time is about relaxation. Grab a friend and get a beer. Work can wait until tomorrow.1.What can be the first step to take the PTO?A.Persuade the family.B.Have a personal rest.C.Ask friends for advice.D.Make a time plan.2.What does the underlined part“let your shoulders drop”probably mean?A.Get you more focused.B.Have you feel relaxed.C.Shake your shoulders often.D.Make you feel more stressed.3.What does the text mainly talk about?A.Tips on how to take your time offB.Skills to manage work and familyC.Advice on how to free yourselfD.Ways of scheduling your workBGlobally, 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 more opportunities 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.CThe Nez Perce Indians are a tribe that lived in the Pacific Northwest of theUnited States. At the time of the Lewis and Clark expedition (探险队) , which was one of the first journeys by Americans from the Atlantic coast to the Pacific coast and back again, the Nez Perce territory (领土) covered about 17 million acres, covering parts of Washington, Oregon, and Idaho. Butthat was a brief sweet history.In September 1805, when Lewis and Clark came off theRockieson their westward journey, the entire exploring party was hungry and ill -- too weak to defend themselves.Had the Nez Perce chosen to attack them, they could have put an end to the Lewis and Clark expedition there on the banks ofClearwater River. Instead the Nez Perce welcomed the white Americans and looked after them until they made a full recovery. Thus began a long friendship between the Nez Perce and white Americans. But white men’s greed for land and gold finally broke the friendship.In 1855 Governor Isaac Stevens ofWashingtonTerritoryinvited the Nez Perce to a peace conference. He said there were a great many white people in the country, and many more would come. But the Chief of the tribe atthat time, Old Joseph, replied, “Take away your paper. I will not touch it with my hand.”Things were quiet for a while after that, but not for long. When Old Joseph died, the chiefship was passed onto Young Joseph. In the late 1870s, government officials came to order the Nez Perce to leave theWallowaValleyand then began hard battles between the Nez Perce and the white soldiers. After the tribe had fought thirteen battles and moved 1,600 miles to-wards Canada in an attempt to retreat(撤退) north, Young Joseph, gave in to the United States Army. Here was his famous statement, “Hear me my chiefs. I am tired; my heart is sick and sad. From where the sun now stands I will fight no more forever.”In 1885, Chief Joseph was sent along with manyof his band to the Colville Reservation inWashingtonwhere Joseph continued to lead his band for another 25 years, at times coming into conflict with the leaders of 11 other tribes living on the reservation.(保留地，居留地)8. What isTRUEabout the Lewis andClark expedition?A. They were well cared for by the Nez Perce.B. They ended their expedition on the banks ofClearwater River.C. They started the first battle with the Nez Perce.D. They were the first Americans to travel from theAtlanticto the Pacific.9. What ended the friendship between the Nez Perce and the Whites?A. Old Joseph’s proud mannerB. White men’s increasing demand for land and goldC. A growing number of white men in the landD The breakdown of the peace talk10. Young Joseph gave in at last because ________.A. he grew olderB. he was terribly illC. he hated the warD. he lost other chiefs’ support11. The passage might be followed by a paragraph about ________.A. the customs and traditions of the Nez Perce IndiansB. the last years of Chief Joseph in the Colville ReservationC. lasting fights between the Nez Perce and the whitesD. constant conflicts between the Nez Perce and other tribesDOver 180 teenage girls from LixianCounty No. 1 Middle School in Longnan city, Gansu province, listenedcarefully to a lecture about neuroscience (神经科学). It was delivered by a director of the experimental surgery department at The Second Affiliated Hospital of the Air Force Medical University in Xi’an.The students also joined a science class to make paper rockets to launch into the sky. A plastic bottle was connected with a long pipe joined to the end of the rocket, and students stepped heavily on the middle of the bottle so hard that the air pressure shot the rocket upward.The program started in 2016 as a one-week summer camp in Beijing that invited female students to take science courses and to interact with women in science. It aims to stir (激发) an interest in science and technology among female students.“I’m excited to take the opportunity because it’s been my biggest wish to popularize science among students. They can broaden their eyes and hopefully some of them will devote themselves to the field of neuroscience,” the director says. “It’s necessary to bring more of these activities on campus. I’m willing to communicate with teenagers, some of whom ask deep and thoughtful questions that I would never think of.”The key to science popularization is to imbue (灌输) others with the spirit of science. Some scientific and technological workers have devoted themselves to a job in a certain field and they enjoy the pleasure of scientific research. Female Chinese scientific and technological workers sometimes have to double their efforts to receive the same treatment or recognition as those male scientific workers. However, after years of continued effort, the situation will improve, showing the increasing number of female scientists in China.12. What is the purpose of the program?A. To praise the efforts of women scientists.B. To find out how much girls love science.C. To develop interest in science among girls.D. To show love for students in Western China.13. How does the director think of the program?A. Important.B. Challenging.C. Confusing.D. Serious.14. What is the most important in science popularization?A. Enjoying the fun of scientific research.B. Filling people with the spirit of science.C. Holding more scientific activities on campus.D. Forcing students to choose scientific subjects.15. What can we learn from the text?A. One can go anywhere if he/she learns science well.B. People have a stronger sense of science than before.C. Male scientists are much easily recognized than female ones.D.

If you are anywhere close to the area during a game,these fantastic sports events are here for you.San Francisco Giants BaseballThe San Francisco Giants baseball team plays in SF at Oracle Park. This is a fun ballpark because it's always packed with great energy and offers views of the bay. It's one of the most popular San Francisco sports events. The Giants are part of the National League West Division. Since their arrival here in 1958,they have been World Series Champions three times.Golden State Warriors BasketballThe fan base of the Golden State Warriors distributes the whole San Francisco Bay Area as this region's only NBA team.Their regular season runs from late October through mid-April, and all home games are played at the Chase Center in San Francisco.In total, the Warriors has won six NBA championships.San Francisco 49ers FootballThe 49ers are San Francisco's NFL team, though they have recently moved to Levi's Stadium in Santa Clara, about an hour south of SF. The football team was named for the prospectors (探矿者) who arrived in the area in 1849 for the Gold Rush. They’ve won 5 Super Bowl championships, all between 1981 and 1994.San Jose Sharks HockeyThe San Jose Sharks represent the Bay Area in hockey (冰球).They were founded in 1991 as the only Bay Area team to compete in the NHL. Sharks fans love going to these San Francisco sports events at the SAP Center,which they call the Shark Tank,located about an hour southeast of SF.1.Where can a sports fan have a good view of the area?A.The Oracle Park.B.The Chase Center.C.Levi's Stadium.D.The SAP Center2.Which team has claimed the most titles according to the text?A.The Giants.B.The Golden State Warriors.C.The 49ers.D.The San Jose Sharks.3.Where is the passage probably taken from?A.A book review.B.A news report.C.A science fiction.D.A tourist magazine.BThe far side of the moonis a strange and wild region, quite different from the familiar and mostly smooth face we see nightly from our planet. Soon this rough space will have even stranger features: it will be crowded with radio telescopes.Astronomers are planning to make the moon's distant side our newest and best window on the cosmic(宇宙的) dark ages, a mysterious era hiding early marks of stars and galaxies. Our universe was not always filled with stars. About 380,000 years after the big bang, the universe cooled, and the first atoms of hydrogen formed. Gigantic hydrogen clouds soon filled the universe. But for a few hundred million years, everything remained dark, without stars. Then came the cosmic dawn: the first stars flickered, galaxies came into existence and slowly the universe's largescale structure took shape.The seeds of this structure must have been present in the darkage hydrogen clouds, but the era has been impossible toprobeusing optical(光学的) telescopes—there was no light. And although this hydrogen produced longwavelength(or lowfrequency) radio emissions,radio telescopes on Earth have found it nearly impossible to detect them. Our atmosphere either blocks or disturbs these faint signals; those that get through are drowned out by humanity's radio noise.Scientists have dreamed for decades of studying the cosmic dark ages from the moon's far side. Now multiple space agencies plan lunar missions carrying radiowavedetecting instruments—some within the next three years—and astronomers' dreams are set to become reality.“If I were to design an ideal place to do lowfrequency radio astronomy, I would have to build the moon,”says astrophysicist Jack Burns of the University of Colorado Boulder. “We are just now finally getting to the place where we're actually going to be putting these telescopes down on the moon in the next few years.”4. What's the purpose of building radio telescopes on the moon?A To research the big bang. B. To discover unknown stars.C. To study the cosmic dark ages.D. To observe the far side of the moon.5. What does the underlined word “probe” in Paragraph 3 possibly mean?A. Explore.B. Evaluate.C. Produce.D. Predict.6. Hydrogen radio emissions can't be detected on Earth because ________．A. there was no light in the dark agesB. they cannot possibly get through our atmosphereC. gigantic hydrogen clouds no longer fill the universeD. radio signals on Earth cause too much interference7. What can we infer from theunderlined sentence in the last paragraph?A. Scientists have to rebuild the moon.B. We will finally get to the moon's distant side.C. The moon is a perfect place to set up radio telescopes.D. A favorable research environment will be found on the moon.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?DThe common use of Google Maps, a navigation(导航) app on smartphones, raises the age-old question we meet with any technology:What skills are we losing? But also, crucially: What capabilities are we gaining?People who are good at finding their way around or good at using paper maps usually experience lots of confusion with digital maps. For example, they may mess up the direction of north and south, and you can see only a small section at a time. But consider what digital navigation aids have meant for someone like me. Despite being a frequent traveler, I’m so terrible at finding my way that I still use Google Maps almost every day in the small town where I have lived for many years. What seems unnecessary to some has been a significant expansion of my own capabilities.Part of the problem is that reading paper maps requires a specific skill set. There is nothing natural about them. In many developed nations, street names and house numbers are meaningful, and instructions such as “go north for three blocks and then west” usually make sense. In Istanbul, in contrast, where I grew up, none of those hold true. For one thing, the locals rarely use street names, and house numbers often aren’tsequentialeither because after buildings 1, 2 and 3 were built, someone squeezed in another house between 1 and 2, and now that’s 4. But then 5 will maybe get built after 3, and 6 will be between 2 and 3. Besides, the city is full of winding and ancient streets that meet with newer ones. Therefore, instructions as simple as “go north” would require a helicopter. I got lost all the time.But since I used Google Maps, I travel with a lot more confidence, and my world has opened up. And becauseI go to more places more confidently, I believe my native navigation skills have somewhat improved, too.That brings me back to my original question: while we often lose some skills after seeking convenience from technology, this new setup may also allow us to expand our capabilities and do something more confidently. Maybe when technology closes a door, we should also look for the doors it opens.12. How does the author feel about Google Maps?A Confusing. B. Unnecessary. C. Complicated. D. Helpful.13. Which contributes to the difficulty of finding ways in Istanbul?A. Strange street names.B. Ordinary paper maps.C. Complex road arrangements.D. Lack of road instructions.14. What does the underlined word “sequential” in Paragraph 3 probably mean?A. In a fixed order.B. In good condition.C. Of great importance.D. Of the same kind.15. What column of a newspaper may this passage belong to?A. Fashion.B. Opinion.C. Society.D. Geography.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。

2019-2020学年嘉兴市高级中学高三英语第二次联考试卷及答案
2019-2020学年嘉兴市高级中学高三英语第二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AAs the MOOC craze continues to explode, anyone interested in taking an online course faces a tricky question: Which course to take? Here are five aspects that you should consider before you start.(1)What is your learning style?Many MOOCs are video-based. Other courses use presentation formats. Some also require participation in group work. If you want to stay motivated during your course, think about how you enjoy learning.Are you a visual learner, preferring to use images to understand a topic? If so, a video-based course will work well for you. If you are a verbal learner who gains new information by speaking and writing, try a text-based course with lots of note-taking. Social learners, meanwhile, will thrive in forum discussions and project-based assessment.(2)Are you ready to become a full-time student?Be realistic about the time that you can commit to your online studies. Participating in an online course can take as much time and commitment as a class-based program. Check the course requirements and make a plan around your current schedule.(3) Does the course really meet your needs?Whether you are interested in a professional qualification or want to take a personal development course like yoga, there is a MOOC for you. It's easy to get caught up in the excitement of taking lots of free courses in everything that you ever wanted to learn. Before you start a course, think about the end goal. Is the course aimed at beginners or advanced learners? Why do you need this qualification?(4) Do you need a support group?Some people learn best from seeing how others approach the problem. If you are such as learner, you will need to supplement your online lessons with an in-person support group.(5) What kind of certification will you get?Take time to find out what kind of certification is available upon completion of the course, and how you can prove your learning to others - for example, certificates, transcripts or digital badges.1. What kind of MOOC's does the author recommend to verbal learners?A. A video-based course.B. A text-based course.C. A forum-based discussion.D. A project-based assessment.2. What kind of learners need an in-person support group?A. Learners who prefer individual work.B. Learners who are in great need of a certificate.C. Learners who are too busy to become a full-time student.D. Learners who learn best from observing how others address the problem.3. What is the passage mainly about?A. Picking the right MOOC's for you.B. Deciding your learning style.C. Taking the right course you need.D. Choosing a suitable support group.BDragon boating is a team sport that has its root in ancient China. The boats are decorated with a dragon head and tail. In recent years cancer survivor groups have got involved in the sport to help make friends and help rebuild their lives.On a recent Saturday morning, a group of 20 women were on a boat in the Anacostia River in Washington DC. They moved their paddles(船桨)in rhythm to the call of a coach. The women belong to the dragon boat team GoPink! DC, which trains weekly. It also races against other breast cancer survivor teams in dragon boat festivals. As a result, GoPink! DC won medals in this Washington dragon boat festival.Lydia Collins joined five years ago after finding out she had breast cancer. “I was diagnosed with breast cancer.I was demoralized because of my illness - I lost all interest in life and wouldn't even get out of bed to eat. But now I love the team spirit. I just love everything about it. It is like a floating support group on the water.”The paddles are breast cancer survivors and their supporters. Annette Rothemel helped establish(建立)the group in 2006. She is a researcher with the National Institutes of Health as well as a breast cancer survivor. “It is sort of an easy entry sport because on the same boat people at different levels can be doing the same sport.” But Ms Rothemel saysdragon boating can be physically demanding, especially for someone who is sick and getting treatment for cancer.“It’s hard but I think you have to challenge yourself in life. This is something I look forward to. I get to be out here with my sisters and supporters that understand what I’m going through and help motivate me. So it makes me stronger and it makes me feel better,” another cancer survivor Rhonda Hartzel said.Annette Rothemel says the cancer survivors feel a sense of sisterhood and share good times when theypaddle together. She says both feelings are treasured by the team.4. What do the underline wordsdemoralizedIn para.3 probably mean?A. depressedB. anxiousC. astonishedD. awkward5. What can we know about Lydia Collims from the text?A. she helps establish Go Pink !DCB. she tries to find a cure for the cancerC. she benefits from the dragon boat raceD. she gives up hope because of her illness6. How can the dragon boat race help the cancer survivorsA. forget their tough experiencesB. recover physically and mentallyC. get rid of the pains of their cancerD. enjoy their rest life without sufferings7. What does the text tell us about Annette Rothemel?A. she is an expert in studying the cause of the cancerB. she helps the cancer survivors in financial difficultiesC. she believes there is a healthful result from the dragon boat raceD. she thinks it unwise for the patient to join in the dragon boat raceCZaki was small for his twelve years, and he was angry being treated as a child. Farid, his older brother, had been looked upon as a man long before he was Zaki’s age. Every day Farid and the other young Bahraini men went out in their wooden boats to dive for oysters (牡蛎). Many times Zaki begged to go along, but Faridalways refused to let him.So every day Zaki would go to the shallow water to practice. His grandfather, a former diver, would watch him and advise him. All morning, Zaki would practice diving beneath the waves. Every afternoon, again and again he would go underwater and hold his breath. With each day’s practice, his diving improved and he could hold his breath a little while longer. Soon Zaki felt as much at home in the water as he did out of it.Zaki rose early one day. He wanted to compete with his brother. They dived beneath the waves. Zaki opened his eyes and found himself looking into his brother’s face. Farid was smiling with confidence. Slowly, the smile was disappearing from Farid’s face. As more seconds passed, a worried look appeared on Farid’s face. Farid wasrealizing that Zaki could possibly beat him. Looking into Farid’s eyes, Zaki suddenly understood what losing could mean to his brother. Never would the villagers allow him to live it down. He would be laughed at by losing to a little child. Almost without thinking, Zaki kicked his feet and rose to the surface of the water a second before Farid’s head appeared beside him.The men around them cheered and patted Farid on the back. Farid, however, put his arm around Zaki’s shoulders. “Today,” Farid announced, “we shall have a new diver among us.” Then quietly, for Zaki’s ears alone, he said “Thank you, my brother.” And Zaki knew that they both had learned that it takes more than strength to makea man.8. What is the second paragraph mainly about?A. Zaki’s grandfather was a good diver.B. Zaki liked staying at home every day.C. Zaki practised hard in the water daily.D. Zaki’s grandfather encouraged him to dive.9. Which of the following best describes Zaki according to paragraph 3?A. Considerate.B. Ambitious.C. Confident.D. Adventurous.10. What can we infer from the last sentence of the text?A. Farid beat his little brother easily.B. Zaki was as strong as his brother.C. Zaki regretted losing the competition.D. Both Farid and Zaki had grown up.11. What is the best title for the text?A. Farid’s PrideB. Zaki’s ChallengeC. Brothers’ CompetitionD. Grandfather’s AdviceDThe idea came to him when he least expected it. Alvin Irby was at a barbershop when he saw one of his former students sitting in the shop with a bored look on his face. That’s when Irby realized that by pairing barbershops and books, he might be able to inspire young boys to read.Alvin Irby, a former kindergarten and first-grade teacher, knows how important it is for young children to read. He also knows that young boys in particular often don’t have adult male role models who inspire them to read.“Many young boys may literally never see a man reading in school during the years when they’re learning to read because there are so few male elementary school teachers,” Irby toldMashable.That’s where the barbershops come in. Four years ago, Irby launched Barbershop Books as a way to not just get books into the hands of young boys, but also to create community reading spaces in a place where kids go frequently. Since itsinceptionin 2013, the program has created kid-friendly reading spaces in 50 barbershops in 12 states throughout the United States.Irby isn’t the first person to see the connection between barbershops and books and boys. Hair stylist Courtney Holmes, launched a program a few years ago offering free haircuts to kids as long as they read to him while he cuts their hair.That’s the kind of environment that Irby wants to promote with his program. The reading spaces created by Barbershop Books help to spark an interest in books by showing kids that reading is about more than just spelling and vocabulary skills, it’s about making reading a low-stress activity that can help them relax, laugh and have fun.“Our belief is that if we can create positive reading experiences early and often for young boys, then they will choose to read for fun,” Irby noted, adding, “This is really what Barbershop Books is about, getting young boys to say three words: I’m a reader.”12. What happened to Alvin when he was at a barbershop?A. He found it easy for young people to get bored.B. He offered a barbershop to his former student.C. He thought of a way to encourage young readers.D. He realized the importance of reading for young boys.13. What is the function of Barbershop Books?A. To attract more customers who love films.B. To provide free haircuts to book lovers.C. To show the influence of reading on children.D. To create a reading environment fbr children.14. It can be inferred from the passage that ________.A. reading is a low-stress activity that is relaxingB. Barbershop Books is only suitable for young boysC. Irby attaches great importance to school educationD. Barbershop Books can arouse (引起) young people’s interest in reading15. What does the underlined word “inception” in the 3rdparagraph mean?A. discovery.B. success.C. popularity.D. beginning.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。

Suspicions havebeen that birds may regard the open areas behind glass as safe passageways. Or they may mistake the reflected trees for the real thing.Researchers would like to reduce collisions, which requires a solid understanding about what makes a bird more or less likely to die by crashing into a building in the first place.“There was ly little known at a broad scale. Previous studies were at one small study site.'' Jared Elmore, a graduate student in natural resource ecology and management atOklahomaStateUniversity. So he and his colleagues used a previously created data set of building collisions for birds at 40 sites throughoutMexico,Canadaand theU.S.The first finding was obvious: bigger buildings with more glass kill more birds. But the details were more remarkable. "We found that life history predicted collisions. Migrants(候鸟), insect-eaters and woodland-inhabiting species collided more than their counterparts(同类).”Most migratory species travel at night, when lights near buildings can distract or disorient(使迷失方向)them. And Elmore thinks that insect-eating birds might be attracted to buildings because their insect prey(猎物)is attracted to the lights. He suspects that woodland species get tooled by the reflections of trees and bushes in the windows. The results are in the journal Conservation Biology.By understanding which birds are more likely to collide with buildings, researchers can perhaps determine the best way to adapt buildings, or their lighting, to help prevent such accidents. And by knowing risks, along with migration timing and behavior, building managers can better predict when birds are at their greatest danger - and improve lighting strategics accordingly.Elmore's next project will use radar to help predict bird migrations. " I think that would maybe go a long way in terms of providing information to people, to the public, to building managers, on when they can get the most benefit in terms of lights-out policies."4. What is the possible reason for birds' crashing into buildings?A. They didn't see the buildings.B. They took reflections for reality.C. They assumed the windows to be open.D. They considered buildings as safe routes.5. What is Jared Elmore's study different from the previous ones?A. It created a new data set.B. It went beyond national borders.C. It covered a wider range of sites.D. I’ll studied some specific bird species.6. What was the most noticeable finding of Jared Elmore's study?A. Migratory species travel at night.B. Birds tend to be misled by glasses.C. Bigger buildings cause more collisions.D. Birds living habits give rise to collisions.7. Which of the following can help reduce bird collision?A. Adjust the lightening system.B. Attach radars to each building.C. Adopt strict lights-out policies.D. Ban using glasses on buildings.C“They’re harming your brain.” “They’re ruining your eyes.” “They’re turning you into a violent person.” The words said publicly against video games are so common, but are these worries founded on actual science? Countless studies have offered different opinions on whether video games are bad for you. We’ve rounded up the most notable reports and studies below, so you can weigh up the evidence for yourself.In 2013,psychologist(心理学家) Simone Kuhn studied the influences of spending long hours on video games on the brains of young adults and found that several areas became bigger than before. These areas are connected with highercognitive functions(认知功能), memory formation andfinemotor(精细运动) function.Last year, psychologists said that video game players who favour violent games are more likely to be violent when offline. Dr. Mark Appelbaum of the American Psychological Association said that there was a relation between violent video game use and increases in violent behaviour.Dr. Daphne Bavelier is an expert in the field of Brain & Cognitive Sciences. Bavelier presented the audience with a colour-word test, where non-gamers are easily puzzled by the test, and those who spend long periods playing on their computers are more likely to pass the test with flying colours.“Actually, those video game players have many other advantages in terms of attention,” said Bavelier, “and one part of attention which is also improved for the better is our ability to follow the movements of objects.”“So, in a sense, when we think about the influence of video games on the brain, it’s very similar to the influence of wine on the health. There are some very poor uses of wine. There are some very poor uses of video games. But when drunk in reasonable amounts, and at the right age, wine can be very good for health,” said Bavelier.8. What can be learned from Simone Kuhn’s study？A. Video games make you happier.B. Video games make your brain grow.C. Video games play a key role in memory.D. Video games teach you how to learn fast.9. What was Dr. Mark Appelbaum’s attitude towards video games？A. He was against them.B. He was hopeful of them.C.He was in favour of them.D. He was uncertain about them.10. Which of the following may Dr. Daphne Bavelier agree with？A. Video games fix attention problems.B. Video games make kids do well in exams.C. Video games encourage violent behaviour.D. Video games help increase colour knowledge.11. Why are the uses of wine mentioned in the last paragraph？A. To remind people to avoid video games.B. To show the disadvantages of video games.C. To help people learn more about video games.D.To ask people to make good use of video games.DThree years ago, a group of researchers at Cornell University Food and Brand Lab had a guess. They knew that many apples being served to kids as part of the National School Lunch Program were ending up in the trash, almost untouched. But unlike others, they wondered if the reason was more complicated than simply that the kids didn’t want the fruit.They thought the fact that the apples were being whole, rather than sliced (切片的), was doing the fruit nofavor. And they wanted to prove this idea.They carried out a study at eight schools and found that fruit consumption (消费) jumped by more than 60 percent when apples were served sliced. They then made a follow-up study at six other schools, which not only showed the same result, but further supported. The whole apple consumption at schools that served sliced apples reduced by about 50 percent than before.Based on these results, it seems that even the simplest forms of inconvenience can influence us. Sliced apples just make more sense for kids. The hardest part is getting kids to start eating fruit, and that’s exactly why sliced apples are the way to go. A child holding a whole apple has to break the skin, eat around the core (果核), and deal with the inconvenience of holding a large fruit. These problems might seem silly or unimportant, but they’re important when you’re missing teeth or have braces (牙箍), as so many kids do.Sometimes what seems like a really small inconvenience actually makes a huge difference.12. What can we learn from Paragraph 1?A. Lots of apples served to kids were wasted.B. Researcher supported the lunch program.C. Apples are not the only acceptable fruit for kids.D. The lunch program was well worth spreading.13. What did researchers want to prove?A. Kid didn’t want the fruits.B. Kids favored the whole apples.C. Kids preferred to the sliced apples.D. Kid’s eating habits influenced fruit consumption.14.
