2020届乌鲁木齐市第一中学高三英语第二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AAmid the coronavirus outbreak, the U. S. Department of Homeland Security recommends having at least a two - week supply of water and food.PotatoesShelf life：2 to 5 weeks if stored in a cool, dry, dark placeYukon Gold, red, and fingerling potatoeswill last from two to three weeks. Larger white potatoes can last for three to five weeks. Sweet potatoes have about the same shelf life. Don't store them next to onions, however. The two might go together well in cooking, but raw, each gives off gases and moisture that might cause the other to spoil faster.Tea※Shelf life：6 to 12 months past "sell - by" dateDried tea leaves, whether loose (in a sealed container) or in teabags (in an unopened box) can easily last a year or more if they' re not subjected to damp or humidity. However, the tea does tend to lose flavor over time.Peanuts● Shelf life：1 to 2 monthsPeanuts in their shell, especially when kept cool and dry, are perfectly happy in the cupboard for as long as two months.Canned fruits and vegetables● Shelf life：1 to 2 years past "sell - by” dateCanning is an extremely efficient means of preserving food. Generally speaking, if canned foods aren't subjected to extreme heat, their contents should stay good for two years or more. Be aware, however, of dented cans or those with swollen tops, which may indicate the presence of bacteria inside.1. Which can go bad faster if stored with onions?A. Potatoes.B. Tea.C. Peanuts.D. Canned fruits and vegetables.2. What is special about tea?A. The flavor of tea can always remain the same.B. Tea leaves are better to be preserved in an open jar.C.

Shapes of cans.B. Categories of foods.C. Decline of the temperature.D. Exposure to high temperature.BLosing your ability to think and remember is pretty frightening. We know the risk of dementia (痴呆症) increases with age. But if you have memory slips you probably needn’t worry. There are pretty clear differences between signs of dementia and age-related memory loss.After age 50, it’s quite common to have trouble remembering the namesof people, places and things quickly, says Dr. Kirk Daffner of Brigham and Women’s Hospital inBoston.The brain ages just like the rest of the body. Certain parts become smaller, especially areas in the brain that are important to learning, memory and planning. Changes in brain cells can affect communication between different regions of the brain. And blood flow can be reduced as blood vessels narrow.Forgetting the name of an actor in a favorite movie, for example, is nothing to worry about. But if you forget the plot of the movie or don’t remember even seeing it, that’s far more concerning, Daffner says.When you forget entire experiences, he says, that’s “a red flag that something more serious may be involved”. Forgetting how to operate a familiar object like a microwave oven, or forgetting how to drive to the house of a friend you’ve visited many times before can also be signs of something going wrongBut even then, Daffner says, people shouldn’t panic. There are many things that can cause confusion andmemory loss, including health problems like temporary stoppage of breathing during sleep, high blood pressure, or depression, as well as medications (药物) like antidepressants.You don’t have to figure this out on your own. Daffner suggests going to your doctor to check on medications, health problems and other issues that could be affecting memory. And the best defense against memory loss is to try to prevent it by building up your brain’s cognitive(认知的) reserve, Daffner says.“Read books, go to movies, take on new hobbies or activities that force one to think in novel ways, ” he says. In other words, keep your brain busy and working. And also get physically active, because exercise is a known brain booster4. Why does the author say that one needn’t be concerned about memory slips?A. Not all of them are related to one’s age.B. Not all of them are symptoms of dementia.C. They occur only among certain groups of people.D. They are quite common among fifty-year-old people.5. Which memory-related symptom should people take seriouslyA. Totally forgetting how to do one’s daily routines.B. Inability to recall details of one’s life experiencesC. Failure to remember the names of movies or actorsD. Occasionally confusing the addresses of one’s friends.6. What should people do when signs of serious memory loss show up?A. Check the brain’s cognitive reserve.B. Stop medications affecting memory.C. Turn to a professional for assistance.D. Exercise to improve their well-being7. What is Dr. Daffner’s advice forfight against memory loss?A. Having regular physical and mental checkups.B. Taking medicine that helps boost one’s brain.C. Engaging in known memory repair activities.D. Staying active both physically and mentallyCJapan's prime minister encouraged the decision to ban viewers, even family members, by issuing a state of emergency order in Tokyo earlier this month in response to rising COVID-19 case numbers.From the perspective of sports psychologists, an Olympics without fans is a real-life science experiment that is helping researchers and clinicians to comb through the true impact of a crowd of fans on its players—and on viewers at home. The strange circumstances under which the games are held may place unexpected pressure on some athletes. On Tuesday, superstar gymnast Simone Biles dropped out of the women's team event, telling teammates and reporters she wasn't in the right “headspace” to compete. “It's been really stressful this Olympic Games. There are a lot of different variables going into it,” Biles told the Washington Post.The 2020 Summer Olympics bears similarities and differences to other major sporting events without viewers.The English Premier League supplemented (增加) game broadcasts with crowd noise from the soccer video game FIFA 20, mixed with game audio in real time. A Taiwanese baseball team and German soccer team began populating stands with cardboard cutouts of fans, and the trend caught on internationally.Jamey Houle, the lead sports psychologist for Ohio State University Athletics and a former Al-American gymnast, says competitive athletes are trained in visualization— imagining performing a certain action or motion, such as doing a roundoff back handspring in gymnastics. Without moving a muscle, players using visualization can solidify neural (神经的) connections and activate their motor cortex (皮层). To visualize most effectively, Houle says, athletes working with sports psychologists will try to simulate as closely as possible the conditions of actual gameplay. Empty stadiums may thus have a measurable impact on players' performance. This phenomenon is grounded in a psychological concept called “social facilitation”, referring to a change in a person's performance that occurs when others are around compared to when a person is alone.8. What caused Biles to drop out of the women's team event?A. The poor physical condition.B. The absence of the audience.C. The fiercely competitive event.D. The influence of crowds of fans.9. What can be inferred from Paragraph 3?A. The Taiwanese baseball team is a success.B. The tendency mentioned is popular among some sporting events.C. The 2020 Summer Olympics is stricter in preventing the pandemic.D. The crowd noise plays a leading role in the English Premier League.10. How does Houle explain the impact of empty stadiums on players' performance?A. By doing a roundoff back handspring.B. By simulating the conditions of actual gameplay.C. By using the concept called social facilitation.D. By changing the viewers of a player.11. What message does the author mainly convey in the text?A. Athletes should be trained in visualization.B. Audience should be admitted to the Olympics.C. Social facilitation is helpful to sporting events.D. Viewers present may influence players' performance.DWhen the COVID-19 hit and supermarket shelves were empty, Chris Hall and Stefanny Lowey decided they no longer wanted to rely on others for food. The couple, who live on Pender Island in BritishColumbia, Canada, decided to start a year-long challenge where they wouldn't buy a single thing to eat. Instead they would grow,raise or catch everything—right down to sugar, salt and flour. Now, five months in, they say the challenge has changed their lives.Chris, 38, said, “It has always been something that we have wanted to do. We have had a garden and grown vegetables for a long time already. When the COVID-19 hit, it gave us that extra push that we needed to do it. We were both out of work when we started, and with the reality check of grocery stores running out of items, it gave us even more motivation to see if we could look after ourselves.”The pair spent the months before building a house for chickens, ducks and turkey as well as studying as much as possible to figure out where they would get all the things they needed. Chris adds, “We had to learn so many new things like how to grow mushrooms, process our Stevia plants, and harvest salt from the ocean. We spent a lot of time reading and studying online to figure out all the things we were going to need to do.”Now after five months, they both feel its been going well but Chris admits the first few weeks were difficult. “The first three weeks were very challenging as our bodies adjusted to cutting out coffee, wine and sugar all on the same day,” he says. “After three weeks our energy levels balanced out and our wishes reduced and now we feel great.” Now February has ended. As they come through winter, they feel positive about continuing with this way of living, with their challenge officially ending in August.12. Why did the pair decide to produce foods on their own?A. They were isolated by Pender Island.B. They couldn't afford to buy them because they were out of work.C. They believed it's good for their health.D. They could hardly buy them in shops.13. Which words can be used to describe the couple?A. Rich and generous.B. Helpful and positive.C. Optimistic and self-dependent.D. Motivated and brave.14. What can we learn from the last paragraph?A. Their challenge may last about eleven months in total.B. They were discouraged by the difficulty at first.C. They had difficulty because they wanted more.D. They couldn't adjust their bodies to the hard work after three weeks.15. In which column may you read such a passage?A. Sports.B. Agriculture.C. Lifestyle.D. Business.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学年乌鲁木齐市实验学校高三英语第二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AThough online ordering is popular in the UK today，handson experience still attracts many buyers' attention.Oxford StreetLondon is a shoppers' paradise，and most visitors head for Oxford Street.Halfway along is Selfridges，one of the world's first department stores where the architecture and window dressing impress you even before you go in.There are at least four other major stores on this street，plus Europe's largest music shop.In December the atmosphere is especially festive because of the Christmaslights which are always lighted by a politician，a great sportsman，or a super star.Kensington High StreetA fashionable area for shopping is Kensington High Street.One of its department stores even has a roof garden—good for relaxing between purchases.There's also an organic food superstore.Borough MarketYou can't visit London without going to a supermarketOne of the oldest and best for food is probably Borough Market on the south bank of the Thames.Get off the underground at London Bridge and wander among fresh fish stalls，bakeries，and fruit and vegetable sellers.You can also buy specialities to take away，like cheeses，pork pies，mustard and chutney.More places for bargainsPortobello Road Market on a Saturday is your best choice for jewelry or collector's items.It's a shortwalk from the underground station at Notting Hill Gate and you never know what you will find.For clothes，Camden Market is the place.It gets a little crowded at the weekends，though.Convent Garden Market offers great experience for the simple pleasure of looking at jewelry and gifts.1.Oxford Street becomes special in December for ________.A.the wonderful window dressingB.the Europe's largest music shopC.the lights lighted by a famous personD.many bargains to choose from2.To enjoy food，you can goto ________.A.Camden MarketB.Borough MarketC.Kensington High StreetD.Portobello Road Market3.Where is this passage probably taken from?AA science book. B.A traveler's journal.C.A news report.D.A trip guide.BThere have been many fine films over the past several years aboutcharacters struggling with Alzheimer’s disease. But few of them have gone as deeply and frighteningly into the corners of adeterioratingmind as The Father,a powerful new drama built around a spellbinding performance from Anthony Hopkins.At this point in his long career,Hopkinswould seem to have exhausted his ability to surprise us, but his work here is nothing short of astonishing. His character, also named Anthony, is 80 years old and has dementia. At the beginning of the movie, his daughter, Anne — played by Olivia Colman — stops by hisLondonapartment to check on him. Her father's condition has taken a turn for the worse, and his temper has become severe enough to send his latest live in nurse packing. Anthony is stubborn and defiant and insists that he can manage on his own. But that's clearly not the case, given his habit of misplacing his things and his inability to remember names and faces, Anne's included.As The Father goes on, the more it becomes clear that it's his own mind that's playing tricks on him. What makes the movie so unsettling is the way it wires us directly into his subjective experience, so that the foundations of the story seem to shift at random from scene to scene. A man suddenly appears in the apartment, claiming to be Anne's husband, which is odd, since just a few moments earlier, Anne seemed to be single. Anne goes out shopping for groceries, but when she returns, she's played not by Olivia Colman but by another actress, Olivia Williams. Even the apartment itself begins to shift. You notice puzzling differences-wasn't there a lamp on that hallway table just a moment ago?The story in The Father may be complicated but it's also heartbreakingly simple: man grows old and loses his memory, and his daughter, after lifetime of love and devotion, must begin the long painful process of saying goodbye.Hopkinsshows us Anthony's struggle to keep his sense about him. It's a striking performance-and animpossible one to forget.4. What does the underlined word “deteriorating” mean in the first paragraph?A. Worsening.B. Narrowing.C. Recovering.D. Improving.5. What do we learn about the character Anthony in the movie?A. He can take care of himselfB. He drives away the nurses.C. He is easy-going and forgetful.D. He lives with his daughter all the time.6. The shift of scenes in the movie is designed to .A. build the dramatic tension in the family.B. show off the well-designed story line.C. frighten the movie-goers with mysterious plot.D. involve the viewers into thedisordered memories.7. What does the author think ofHopkins?A. He has run out of his talent.B. He is not suitable for the roleC. He masterly plays the old man.D. He presents an odd performance.CNewspapers in Great Britainvarygreatly in their ways of carrying the news. There are serious papers for those who want to know about important happenings everywhere, both at home and abroad. There are popular newspapers for those who prefer entertainment to information.The London newspaper that is best known outside Great Britain is probably the Times. It began in 1785, and has a high reputation for believable news and serious opinions on the news. It calls itself an independent paper, which means that it does not give its support to a particular political party. Its leading articles give the opinions of the editors, not those of the owners of the paper.Letters to the editor are printed in the newspaper. These parts of the Times are always interesting. Most of the letters are serious subjects. But from time to time there will be long letters on the subject which is not at all serious, perhaps on a new fashion of dress, or the bad manners of the young people, compared with manners of thirty years ago.8. If you want to get pleasure, please buy yourself _________.A. a serious newspaperB. foreign newspaperC. any independent paperD. a popular newspaper9. The Times has been famous to outside Great Britain for ________ years.A. 19B. 85C. 236D. 22910. The Times is an independent paper because ________.A. it supports no political partiesB. it is not controlled by the British GovernmentC. it gives special support to all the political parties.D. the editor’s opinions are not examined by the owners of the paper11. The underlined word “vary” in the passage probably means “_________”.A. improveB. compete with each otherC. are differentD. keep in touch with each otherDYou've probably heard it suggested that you need to move more throughout the day, and as a general rule of thumb, that "more" is often defined as around 10,000 steps. With many Americans tracking their stepsvia new fitness-tracking wearables, or even just by carrying their phone, more and more people use the 10,000-step rule as their marker for healthy living. Dr. Dreg Hager, professor of computer science at Johns Hopkins, decided to take a closer look at that 10,000-step rule, and he found that usingitas a standard may be doing more harm than good for many.“It turns out that in 1960 in Japan they figured out that the average Japanese man, when he walked 10,000 steps a day burned something like 3,000 calories and that is what they thought the average person should consume so they picked 10,000 steps as a number” Hager said.According to Hager, asking everyone to shoot for 10,000 steps each day could be harmful to the elderly or those with medical conditions, making it unwise for them to jump into that level of exercise, even if it's walking. The bottom line is that 10,000 steps may be too many for some and too few for others. He also noted that those with shorter legs have an easier time hitting the 10,000-step goal because they have to take more steps than people with longer legs to cover the distance. It seems that 10,000 steps may be suitable for the latter.A more recent study focused on older women and how many steps can help maintain good health and promote longevity (长寿).The study included nearly 17,000 women with an average age of 72. Researchers found that women who took 4,400 steps per day were about 40% less likely to die during a follow-up period of just overfour years: Interestingly, women in the study who walked more than 7,500 steps each day got no extra boost in longevity.12. What does the underlined word "it' in Paragraph 1 refer to?A. The phone recording.B. The 10,000-step rule.C. The healthy living.D. The fitness-tracking method.13. What does Paragraph 2 mainly talk about?A. How many steps a Japanese walks.B. How we calculate the number of steps.C. If burning 3,000 calories daily is scientific.D. Where 10,000 steps a day came from.14. Who will probably benefit from 10,000 steps each day according toHager?A. Senior citizens.B. Young short-legged people.C. Healthy long-legged peopleD. Weak individuals.15. How many steps may the researchers suggest senior citizens take each day?A. 4,400 steps.B. 10,000 steps.C. 2,700 steps.D. 7,500 steps.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。

We settled in our Airbnb accommodation, a cozy apartment, not long after we arrived inHobart, the capital city.After briefing us on the kitchen's facilities and the whereabouts of the bedroom and bathroom, our hostess Geraldine resumed her ironing work, which seemed to have been interrupted by our arrival.She was ironing what looked like security guard uniforms, and we soon found out that she worked in a local prison. And when she detected the curiosity in our tones, she offered a tour at the prison in her SUV. My friend and I exchanged a “this is incredible” look and said “yes” immediately.As we drove, she told us about the buildings that we were passing, the local market and how to get to MONA,Tasmania's well-known contemporary art gallery.And of course we got to hear some background information about the prison. According to our hostess, it currently holds Martin Bryant, a notorious criminal who cheated 35 people out of their property. We could see the high level of security from the layers upon layers of wires surrounding the gray structure inside.Getting to know a city in such a local way is something I would never be able to do by talking to a hotel receptionist, and this is what I like best about the apartment-sharing experience, not to mention the fact that it's usually cheaper than hotel rooms.But I'm fully aware of the risks of Airbnb, which is why I did my homework before booking online—I checked the reviews of the accommodation to avoid possible safety problems.That said, it is the mutual trust between a host and a guest that fascinates me—the interesting feeling of building a bond with a total stranger.4.

Doubtful.CA Singaporean company will feed airport food waste to mealworms before turning them into fish feed, aiming to cut the country's use of imported feed and offer a continuous alternative.Blue Aqua Internationalwill partner with Dnata, an air and travel services provider, to change organic waste at Singapore's Changi Airport into insect protein for aquacultural use, according to a statement Tuesday.The project looks to replace traditional fish and soybean meal as the main sources of protein for aquafeed. The insects will eat the food waste and change it into part of the body containing about 60 per cent protein. The dried baby worms will then be made into feed.These mealworms can be a continuous solution to several problems. Using a small land and giving out less carbon, they turn food waste into feed and offer an alternative source of protein. Ynsect SAS, a small French business that keeps mealworms to feed fish and pets, attracted money from investors includingIron Manmovie actor Robert Downey Jr. in a round of fund-raising last year.The deal will give Singapore's farmers access to domestically produced animal feed, which is traditionally bought from abroad. The Southeast Asian nation imports more than 90 percent of its food and has set a goal to produce a third of its food locally by 2030. It also aims to achieve a general recycling rate of 70 per cent by then. Presently, less than 20 per cent of Singapore's food waste is recycled.As part of the partnership, Dubai-based Dnata will add Blue Aqua to its list of suppliers to buy locally farmed seafood for its catering service.8. What is the function of mealworms?A. To cut the use of imported fish feed.B. To eat food waste and make fish feed.C. To domestically produce animal feed.D. To replace traditional fish and soybean meal.9. What does Paragraph 4 mainly talk about?A. The producers of the feed.B. The purpose of the projectC. The advantages of the project.D. The composition of the feed.10. What can we infer about Singapore from Paragraph 5?A. It is a rich country.B. It is short of self-produced food.C. Its recycling rate is very high now.D. Its farmers don't support the deal.11. What is the text mainly about?A. A new way to produce fish feed.B.An introduction to a company.C. A plan to reduce food waste.D. A deal to protect farmers.DA lot of us lose life’s tough battles by starting a frontal attack—when a touch of humor might well enable us to win．Consider the case of a young friend of mine，who hita traffic jam on his way to work shortly after receiving an ultimatum about beinglate on the job．Although there was a good reason for Sam’s a being late—serious illness at home—he decided that this by-now-familiar excuse wouldn’t work any longer．His supervisor was probably already pacing up and down preparing a dismissal speech．Yes，the boss was．Sam entered the office at 9：35．The place was as quiet as a locker room；everyone was hard at work．Sam’s supervisor came up to him．Suddenly，Sam forced a grin and stretched out his hand．“How do you do！” he said．“I’m Sam Maynard．I’m applying for a job，which，I understand，became available just 35 minutes ago．Does the early bird get the worm？”The room exploded in laughter．The supervisor“clamped off”a smile and walked back to his office．Sam Maynard had saved his job—with the only tool that could win，a laugh．Humor is a most effective，yet frequently neglected，means of handling the difficult situations in our lives．It can be used for patching up differences，apologizing，saying “no”，criticizing，getting the other fellow to do what you want without his losingface．For some jobs，it’s the only tool that can succeed．It is a way to discuss subjects so sensitive that serious dialog may start a quarrel．For example，many believe that comedians on television are doing more today for racial and religious tolerancethan people in any other forum．12. Why was Sam late for his job？A. Because he was ill．B. Because he got up late．C. Because he was caught in a traffic jam．D. He was busy applying for a new job．13. The main idea of this passage is ________．A. Sam Maynard saved his job with humorB. humor is important in our livesC. early bird gets the wormD. humor can solve racial discriminations14. The phrase “clamped off” in Paragraph 3 means ________．A tried to hold back B. tried to setC. chargedD. gave out15. Which of the following statements can we infer from the passage？A. Many lose life’s battles for they are lacking in a sense of humor．B. It wasn’t the first time that Sam came late for his work．C. Sam was supposed to come to his office at 8：30．D.

2020届乌鲁木齐市实验学校高三英语第二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ABird migration is described as the regular, seasonal movement of bird populations from one place to another and back again.The longer days and rich food of the northern summer provide greater chances for birds to feed their young. The longer daylight hours and enormous food resources allow birds to lay larger eggs than those of related non-migratory species that remain in the tropics all year round. As the days shorten in autumn and the breeding period is over, the birds return to warmer regions where the available food supply differs little with the seasons changing. The advantages of migration make up for the high stress, physical exertion（消耗）, and other risks of the migration.Day length is the primary environmental factor that encourages birds to prepare for migration. They have an increased appetite which results in weight gaining, giving them the fat reserves that provide energy for their migratory flight. They also show more activity at night, which is when most birds migrate. While the length of day is the primary reason for migration, birds also respond to temperature changes. For example, if a spring is late and the temperature is lower than normal, birds delay migration; if a spring is early, birds also begin migration early.The timing of the migratory cycle must allow birds to arrive on the breeding site so that there is time tobuild a breeding place, mate, lay the eggs, and hatch the young before the rich food is available to feed the young in the nest. Similarly, if birds wait until the climate in their northern breeding grounds becomes tolerable(可忍受的), there will be no time togain the necessary weight that provides the energy needed for their southbound migration.1. Why do birds migrate to the north in spring?A The temperature in the south has risen.B. They like traveling and enjoy the journey.C. The summer there is warmer than that in the south.D. The environment there is more suitable for them to feed their baby birds.2. What are the two factors that cause birds to migrate?A. Day length and food supply.B. Night length and high stress.C. Temperature changes and daylength.D. Food supply and temperature changes.3. Which can be the best title for the text?A. Birds' LifeB. Birds' MigrationC. Birds' Breeding HabitsD. Birds' Living EnvironmentBFrom Mozart to Metallica, tons of people enjoy listening to various types of music while they paint, write, or draw. Most believe that music helps increase creativity, but an international study conducted by English and Swedish researchers is challenging that view. The study results wereechoedby scientists fromLancasterUniversity, and theUniversityofGavle, saying their findings show music actually weakens creativity.To reach their conclusions, researchers had volunteers complete verbal problems designed to inspire creativity while sitting in a quiet room, and then again while music played in the background. They found that background music significantly weakened the volunteers’ ability to complete tasks connected with verbal creativity. The team also tested background noises like those commonly heard in a library, but found that such noises had no influence on subjects’ creativity.The tasks were simple word games. For example, volunteers were given three words, such as dress, rise, and flower. Then, they were asked to find a single word connected with all three that could be combined to form a common phrase or word. The single word, in this case, would be “sun” (sundress, sunrise, sunflower). Volunteers completed the tasks in either a quiet room, or while listening to two different types of music: rock music or light music“We found strong evidence of weakened performance when playing background music in comparison to quiet background conditions,” says co-author D. Neil McLatchie ofLancasterUniversity. He and his colleagues find that music negatively influences the verbal working memory processes of the brain, preventing creativity. Also, as far as the library background noises having seemingly no effect, the study’s authors believe that was the case because library noises create a “regular state” environment that doesn’t affect concentration.“To conclude, the findings here challenge the popular view that music increases creativity, and instead show that music, whatever type it is, is always a disadvantage for creative performance in problem solving,” the studyreads.4.

They found that the most environmentally friendly and cost-effective approach would be for more food producers to adopt the nitrogen-efficient “intensive” farming method, which involves the heavy use of labor and the production of more crops per acre.This approach was shown to be more effective than the “extensive” farming currently practiced by many poor nations, a method that includes clearing more new land to produce more food.Different farming methods produce significantly different yields, the researchers found — in 2005, the crop yields for the wealthiest nations were more than 300 percent higher than what the poorest nations produced.According to their analysis of the effects of extensive farming, if poorer nations continue using this method,by 2050theywill have cleared an area larger than theUnited States, about 2.5 billion acres. However, if wealthy nations help poorer nations to improve food yields by incorporating(吸收) intensive farming practices, that number could be reduced to half a billion acres.The researchers stress that the environmental effects of meeting future food demand depend on how global agriculture expands and develops.“Our analyses show that we cansave most of the Earth’s remaining ecosystems by helping the poorer nations of the world feed themselves,” Tilman said.8. What is the best title of this passage?A. The World Will Need Double Food by 2050B. Man Will Face the Risk of Lacking Food in the FutureC. Future Farmers Hold Environment’s Fate in Their HandsD. Different Farming Methods Produce Significantly Different Yields9. The character of the extensive farming is ________.A. very cost-effectiveB. to produce more crops per acreC. at cost of more new land to produce more foodD. very environmentally friendly10. It can be inferred from the passage that ________.A. poorer nations mainly use the intensive farmingB. wealthy nations mainly use the extensive farmingC. the intensive farming needs less food producersD. the extensive farming has a worse effect on ecosystems11. According to the passage, the underlined word “they” in the 7th paragraph refers to “________”.A. poorer nationsB. the effects of extensive farmingC. wealthy nationsD.future food demandDBrain cells work to actively forget memories during a specific period of sleep. When we sleep our brains clear out the memories we’ve made while we’re awake, deciding what to keep and what to get rid of. Forgetting is anactive process, explained the authors of the study published in the journal Science. But less is known about this process during the different periods of sleep.They found that during the rapid eye movement (REM ) sleep period — or active sleep when we are thought to dream — special nerve cells appear to actively contribute to forgetting. What are known as melanin-concentrating hormone-producing (MCH) neurons (神经元) sit in the hypothalamus (下丘脑): a part of the brain which helps with a range of functions such as sleep, appetite and emotions. Past research has suggested these cells help to control REM sleep patterns: activating the MCH neurons increasing time spentin this period, while preventingthemreducing changes into this period.The scientists looked at MCH cells in mice, and found 52.8 percent were active during REM sleep, compared with 35 percent when the mice were awake. Study co-author Thomas Kilduff, director of the Center for Neuroscience at SRI International, told Newsweek the team was surprised to find that mice performed better on learning and memory tasks when the MCH cells were prevented. “This result suggests that activation of the MCH neurons may affect memory — that is, MCH neurons may facilitate forgetting,” Kilduff explained.When asked what motivated the study, Kilduff said, “We hope the work could deepen our understanding of Alzheimer’s disease. Understanding the neural basis of learning and memory is a huge area of neuroscience research because of its effects on our everyday lives, as well as diseases such as Alzheimer’s disease. Prior to this work, no one suspected that MCH neurons had anything to do with forgetting,” said Kilduff.12. What can we infer from paragraph 1?A. Forgetting is a passive process.B. The forgetting process is known to us.C. Some memories are forgotten while we are awake.D. Certain memories are removed while we are asleep.13. What does the underlined word “them” in paragraph 2 refer to?A. REM sleep patterns.B. Past researches.C. MCH neurons.D. A range of functions.14. Why did Kilduff’s team conduct the research?A. To publish the study in the journal Science.B. To know more about Alzheimer’s disease.C. To contribute to human’s forgetting.D. To explore our everyday lives.15. What can we know about MCH?A. MCH cells takes control of REM sleep patterns .B. MCH neurons may disturb memory consolidation.C. MCH neurons have nothing to do with forgetting.D. MCH cells help mice performing better on learning.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。
