They said plants had been the key object of study because their reaction to climate change could have an effect on food chains and ecosystem services.The study, published on the Nature website, uses the findings from plant life cycle studies and experiments across four continents and 1,634 species. It found that some experiments had underestimated(低估) the speed of flowering by 8.5 times and leafing by 4 times.“Across all species, the experiments underpredicted the speed of the advance -for both leafing and flowering-that results from temperature increases,”the study said.The design of future experiments may need to be improved to better predict how plants will react to climate change, it said.Plants are necessary for life on the Earth. They are the base of the food chain, using photosynthesis (光合作用)to produce sugar from carbon dioxide and water. They let out oxygen which is needed by nearly every organism on the planet.Scientists believe the world's average temperature has risen by about 0.8℃since 1900, and nearly 0.2℃ every ten years since 1979.So far, efforts to cut emissions(排放)of planet-warming greenhouse gases are not seen as enough to prevent the Earth heating up beyond 2℃this century-a point scientists say will bring the danger of a changeable climate in which weather extremes are common, leading to drought, floods, crop failures and rising sea levels.【语篇解读】本文为科普类文章。
阶段质量检测(四)Unit 4Exploring plantsA卷学业水平达标【说明】本试卷满分120分,考试时间100分钟Ⅰ.阅读理解(共15小题;每小题2分,满分30分)AAlong the river banks of the Amazon and the Orinoco there lives a bird that swims before it can fly, flies like a fat chicken, eats green leaves, has the stomach of a cow and has claws (爪) on its wings when young. They build their homes about 4.6 m above the river, an important feature (特征) for the safety of the young. It is called the hoatzin.In appearance, the birds of both sexes look very much alike with brown on the back and cream and red on the underside. The head is small, with a large set of feathers on the top, bright red eyes, and blue skin. Its nearest relatives are the common birds, cuckoos. Its most striking feature, though, is only found in the young.Baby hoatzins have a claw on the leading edge of each wing and another at the end of each wing tip. Using these four claws, together with the beak(喙), they can climb about in the bushes, looking very much like primitive birds must have done. When the young hoatzins have learned to fly, they lose their claws.During the drier months between December and March hoatzins fly about the forest in groups of 20 to 30 birds, but in April, when the rainy season begins, they collect together in smaller living units of two to seven birds for producing purposes.When danger comes in the form of a snake or a monkey, the young hoatzins — maybe three in one family —jump over the side and into the river. They swim about under the water until it is safe to return and then, using their claws, lift themselves up through the branches and get back home. When they have learned to fly they lose their claws and escape enemies not by swimming but by flying off, in a slow and heavy way, to a neighboring tree.A.Hoatzins in dry and rainy seasons.B.The relatives and enemies of hoatzins.C.Primitive birds and hoatzins of the Amazon.D.The appearance and living habits of hoatzins.解析:选D主旨大意题。

I found myself at a checkout counter behind an elderly woman seemingly in no hurry as she paid for her groceries. A PhD student with not a lot of money, I had hurried into the store to pick up some flowers. I was in a huge rush, thinking of my upcoming evening. I did not want to be late for this date.We were in Boston, a place not always known for small conversation between strangers. The woman stopped unloading her basket and looked up at me. She smiled. It was a nice smile —warm and reassuring —and I returned her_gift_by smiling back.“Must be a special lady, whoever it is that will be getting those beautiful flowers,”she said. “Yes, she' s special,”I said, and then to my embarrassment, the words kept coming out. “It' s only our second date,but somehow I am just having the feeling she's‘the one' ,”Jokingly, I added, “The only problem is that I can' t figure out why she' d want to date a guy like me.”“Well, I think she's very lucky to have a boyfriend who brings her such lovely flowers and who is obviously in love with her,”the woman said. “My husband used to bring me flowers every week —even when times were tough and we didn' t have much money. Those were incredible days; he was very romantic and —of course —I miss him since he' s passed away.”I paid for my flowers as she was gathering up her groceries. There was no doubt in my mind as I walked up to her. I touched her on the shoulder and said, “You were right, you know. These flowers are indeed for a very special lady.”I handed her the flowers and thanked her for such a nice conversation.It took her a moment to realize that I was giving her the flowers I had just purchased.“You have a wonderful evening,”I said. I left her with a big smile and my heart warmed as I saw her smelling the beautiful flowers.I remember being slightly late for my date that night and telling my girlfriend the above story. A couple of years later,when I finally worked up the courage to ask her to marry me,she told me that this story had helped to seal it for her —that was the night that I won her heart.[语篇解读]作者赶着去和女朋友约会,在他买花的途中,偶遇一个”微笑”的老妇人,他们进行了一次”真诚”的谈话……1.Why was the writer in a hurry that day?A.

Elderly people deserve respecting.BWe already know the fastest, least expensive way to slow climate change: Use less energy. With a little effort, and not much money, most of us could reduce our energy diets by 25 percent or more —doing the Earth a favor while also helping our wallets.Not long ago, my wife, PJ, and I tried a new diet —not to lose a little weight but to answer an annoying question about climate change. Scientists have reported recently that the world is heating up even faster than predicted only a few years ago,and that the consequences could be severe if we don' t keep reducing emissions (排放) of carbon dioxide (CO2) and other greenhouse gases that are trapping heat in our atmosphere.We decided to try an experiment.For one month we recorded our personal emissions of CO2. We wanted to see how much we could cut back, so we went on a strict diet. The average US household(家庭) produces about 150 pounds of CO2 a day by doing common place things like turning on air conditioning or driving cars. That' s more than twice the European average and almost five times the global average, mostly because Americans drive more and have bigger houses. But how much should we try to reduce?For an answer, I checked with Tim Flannery, author of The Weather Makers: How Man Is Changing the Climate and What It Means for Life on Earth.in his book, he had challenged readers to make deep cuts in personal emissions to keep the world from reaching extremely important tipping_points,such as the melting (融化) of the ice sheets in Greenland or West Antarctica. “To stay below that point, we need to reduce CO2 emissions by 80 percent,”he said.Good advice, I thought.I' d opened our bedroom windows to let in the wind. We' d gotten so used to keeping our air conditioning going around the clock.I' d almost forgotten the windows even opened.We should not let this happen again. It' s time for us to change our habits if necessary.[语篇解读]我们已经知道,减缓气候变化最快、最经济的办法就是少用能源。

He even reached a point where he felt like he hadnothing to live for.“I was walking around with a lot on my shoulders,” he said.“I couldn’t handle it. I didn’t care about life anymore.” But all that started to change when Wright met Patricia Kelly.“I was seven when I met Mrs Kelly.I wasn’t used to strictness. I wasn’t used to hearing the word ’no’,”said Wright, now 17.Kelly, a former soldier and an equestrian (骑手), took Wright under her wing and helped him find hope in an unlikely place — on a horse.“Wright was like a round peg that everybody kept trying to squeeze into a square hole,” Kelly said.“He was hurting. He needed a place where he could express himself. The riding field became that place for him.”For the last 30 years, Kelly has helped children stay on the right track through her nonprofit, Ebony Horsewomen. The program offers horseback riding lessons and teaches animal science to more than 300 young people a year. By exposing those children to horsemanship, Kelly aims to give them an alternative to the streets and an opportunity to turn their lives around.“We use horses as a hook to create pride, esteem and healing,” said Kelly, 66.“They learn that they have ability. They just have to unlock it.”“When you teach a child to ride a horse, they learn they are the center of their environment,” said Kelly.“Once t hey make that connection, they can change what happens in school, at home and in the community.”语篇解读:本文是一篇记叙文。

They swim about under the water until it is safe to return and then, using their claws, lift themselves up through the branches and get back home. When they have learned to fly they lose their claws and escape enemies not by swimming but by flying off, in a slow and heavy way, to a neighboring tree.长大后爪子消失,能用爪子和喙攀登树木,与成鸟一样也会游泳。

AGustafson, 66, went outside to do yard work one afternoon last September. His nine-year-old white dog, Bounce, played nearby. Suddenly, Gustafson was shocked by a terrifying sound. “I heard a scream from Bounce,” he says. “I ran down the hill and saw Bounc e in the mouth of an alligator (短吻鳄). It was headed right to the water.”The little dog had wandered into the tall grass along a pond nearby. The alligator had sprung (跳跃) from the shallows of the pond and was now holding the dog’s collar between its teeth. It turned away from the bank and began quickly swimming into the water.Gustafson did a flying leap (跳跃), landed on top of the alligator, and grasped the back leg and tail of the alligator and yanked (猛地一拉)—which caused the animal to release (释放) the dog. Bounce paddled frantically (疯狂似地) toward the shore.Then the alligator turned around and sank its teeth into Gustafson’s right hand. “I screamed at the top of my lungs,” he says. “I thought I was in trouble.” Gustafson was able to free his hand when t he beast opened its jaws again. With his injured hand, Gustafson hit the animal and pulled its head underwater.“I yelled at Bounce reminding her to get to the shore, but she was exhausted (精疲力竭的). If I didn’t get to her quickly, she was going under,” he recalls (回忆).When Gustafson released the alligator, it swam away. He grabbed (抓住) Bounce, climbed out of the pond, and carried the dog up the hill to the house.Since the event, Bounce has been subdued (顺从的) and stayed close to home. Gustafson says, too, that the dog has grown more loving. “She likes me a lot more than she used to,” he says, smiling.1. What was Gustafson doing when he heard a scream from Bounce?A. He was playing nearby.B. He was doing yard work.C. He was exercising on the hill.D. He was walking his dog.2. Why did Gustafson scream when he rescued Bounce from the alligator?A. He hurt his right hand.B. His dog was seriously hurt.C. The alligator attacked him.D. He frightened the alligator.3. If Gustafson hadn’t taken Bounce out of the water, the dog would have ______.A. been exhaustedB. survived the attackC. swum out of the pondD. failed to return to the shoreBAre people less happy or more happy the older they get? If you answered more happy, then you were right, based on a study in 2008. It found that people generally become happier and experience less worry after age 50. In fact, it found that by the age of 85, people are happier with their life than they were at 18.The findings came from a Gallup survey of more than 340,000 adults in the United States in 2008. At that time, the people were between the ages of 18 and 85. Arthur Stone in the Department of Psychiatry and Behavioral Science at Stony Brook University in New York led the study. His team found that levels of stress were highest among adults between the ages of 22 and 25. Stress levels dropped sharply after people reached their 50s.Happiness was highest among the youngest adults and those in their early 70s. But the people least likely to report feeling negative (消极的) emotions (情绪) were those in their 70s and 80s.So why would happiness increase with age? One theory is that, as people get older, they become more thankful for what they have and have better control of their emotions. They also spend less time thinking about bad experiences.Happiness is not the only thing that apparently improves with age. In another study this year, people in their 80s reported the fewest problems with the quality of their sleep.The original goal was to confirm the popular belief that aging is connected with increased sleep problems. The study did find an increase during middle age, especially in women. But except for that, people reported that they felt their sleep quality improved as they got older.4. In the text, the author mainly talks about ______.A. the connection between sleep and happinessB. the relationship between aging and happinessC. different levels of happiness in our lifeD. how to find happiness when one ages5. According to the text, as people get older, they will feel ______.A. more optimisticB. less frightenedC. more worriedD. less happy6. When people are in their fifties, they ______.A. have the highest level of stressB. least likely report negative emotionsC. enjoy the highest level of happinessD. experience a sharp drop of stress levels7. According to the last paragraph, a lot of people believe that ______.A. people sleep more when they get olderB. middle-aged women usually sleep lessC. increased sleep problems are part of agingD. they need to improve their quality of sleepCThe Huntington LibraryHoursThe Huntington is closed on Thanksgiving, Christmas Eve, Christmas Day, New Year’s Day, and Independence Day.From November 1st to Labor Day, The Huntington observes summer hours and is open from 10:30 a.m. - 4:30 p.m. daily, except Tuesdays.

Predictions of how many will actually emigrate (移民) from both countries range from 250,000 within five years to 425,000 within two years, reports the Guardian.One method of discourage would-be immigrants may be to convince them that they don’t want to come to Britain at all. Government ministers are reportedly considering a negative ad campaign that focuses on the downsides of British life, in order to “correct the impression that the streets here are covered with gold,” the Guardian reports one government official as saying.There’s been no indication yet of what such a campaign would look like — whether it would focus on the benefits of staying in their countries or make Britain look as unpleasant as possible. The Guardian invited its readers to send in their own suggestions for poster designs, and the results are very unpleasant— bad weather, racial violence, too much drinking, and unreliable public transport.But a negative ad campaign flies in the face of the billions of pounds Britain spent on last summer’s Olympics —partly to build the country’s good reputation. One member of Parliament has said the supposed plans are very ridiculous, according to the BBC.The idea has actually been tried before: the town of Leicester targeted a negative advertising campaign at would-be immigrants from Uganda in the early 1970s —although as the Daily Telegraph notes, the scheme (方案) had little effect.12. The negative advertising campaign is designed to ______.A. show living in the U.K. is very dangerousB. lift the restrictions on the arrival of foreignersC. prevent an expected increase of immigrantsD. refuse to give immigrants the right to live in Britain13. The underlined word “downsides” in Paragraph 3 probably means “______”.A. benefitsB. barriersC. possibilitiesD. disadvantages14. When considering a negative ad campaign, the government ministers are now faced with ______.A. a dilemmaB. a chanceC. a failureD. a coincidence15. From the last paragraph we can learn that _____.A. negative ad campaigns should be promotedB. the negative ad campaign may not help a lotC. the author supports the negative ad campaignD. the number of immigrants will be greatly reduced第二节(共5小题;每小题2分,满分10分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。

Why plants always seem to turn towards the light and climbing plants run up rather than down? The answer is simple: auxin(生长素),a chemical substance that controls growth in plants.Auxin gives away its secretsAuxin is a plant hormone(激素).Darwin was already interested in it in the 19th century.Only in recent years,however,has the hormone started to give away its secrets,thanks to intensive molecular research.Auxin is produced in the young,growing parts of plants and then transported throughout the plant—to a lowlying stem for example.The stem needs tostraighten out as soon as possible to be able to absorb the topside,resulting in the underside growing faster and the stem straightening out.For the same reason,plants in front of windows will always turn to the light.This active regulation of auxin transport allows plants to take ideal advantage of local and changing conditions.A new means of transport for auxinThe transport of auxin through the plant plays a vital role.And,from all appearances,it is not a simple matter.The researchers identified an important new link and means of transport for auxin: PILS proteins (蛋白质).PILS proteins are vital for auxindependent plant growth and adjust the intracellular(细胞内的)storage of the hormone.It is exactly this compartmentalizing (分类) of auxin that seems functionally important for the various developmental processes.Growing crops more efficiently: the right amount of auxin in the right placeHigher auxin levels at the right moment and in the right place result in better growth and greater harvest.Better adjustment of auxin levels would make plants grow more efficiently.The researchers hope to contribute to the development of more efficient growing processes by continuing to sort out auxin transport processes.【语篇解读】本文讲述了现代研究条件下对于植物生长素(auxin)的研究成果。

阶段综合测评(四)(时间:100分钟;满分:120分)Ⅰ.阅读理解(共15小题;每小题2分,满分30分)APlants are flowering faster than scientists predicted(预测)in reaction to climate change, which could have long damaging effects on food chains and ecosystems.Global warming is having a great effect on hundreds of plant and animal species around the world,changing some living patterns,scientists say.Increased carbon dioxide (CO2)in the air from burning coal and oil can have an effect on how plants produce oxygen, while higher temperatures and changeable rainfall patterns can change their patterns of growth.“Predicting species' reaction to climate change is a major challenge in ecology,”said the researchers of several U.S. universities. They said plants had been the key object of study because their reaction to climate change could have an effect on food chains and ecosystem services.The study, published on the Nature website, uses the findings from plant life cycle studies and experiments across four continents and 1,634 species. It found that some experiments had underestimated(低估) the speed of flowering by 8.5 times and leafing by 4 times.“Across all species, the experiments underpredicted the speed of the advance -for both leafing and flowering-that results from temperature increases,” the study said.The design of future experiments may need to be improved to better predict how plants will react to climate change, it said.Plants are necessary for life on the Earth. They are the base of the food chain, using photosynthesis (光合作用)to produce sugar from carbon dioxide and water. They let out oxygen which is needed by nearly every organism on the planet.Scientists believe the world's average temperature has risen by about 0.8℃since 1900, and nearly 0.2℃ every ten years since 1979.So far, efforts to cut emissions(排放)of planetwarming greenhouse gases are not seen as enough to prevent the Earth heating up beyond 2℃ this century-a point scientists say will bring the danger of a changeable climate in which weather extremes are common, leading to drought, floods, crop failures and rising sea levels.【语篇解读】本文为科普类文章。

【答案】 DBThe production of coffee beans is a huge, profitable business, but, unfortunately, fullsun production is taking over the industry and bringing about a lot of damage. The change in how coffee is grown from shade-grown production to full-sun production endangers the very existence of certain animals and birds, and even disturbs the world's ecological balance.On a local level, the damage of the forest required by fullsun fields affects the area's birds and animals. The shade of the forest trees provides a home for birds and other species (物种) that depend on the trees' flowers and fruits. Full-sun coffee growers destroy this forest home. As a result,many species are quickly dying out.On a more global level, the destruction of the rainforest for fullsun coffee fields also threatens (威胁) human life. Medical research often makes use of the forests' plant and animal life, and the destruction of such species could prevent researchers from finding cures for certain diseases.In addition, new coffeegrowing techniquesare poisoning the water locally,and eventually the world's groundwater.Both locally and globally, the continued spread of full-sun coffee plantations (种植园) could mean the destruction of the rainforest ecology. The loss of shade trees is already causing a slight change in the world's climate,and studies show that the loss of oxygengiving trees also leads to air pollution and global warming. Moreover, the new growing techniques are contributing to acidic (酸性的) soil conditions.It is obvious that the way much coffee is grown affects many aspects of life, from the local environment to the global ecology. But consumers do have a choice. They can purchase shade-grown coffee whenever possible, although at a higher cost. The future health of the planet and mankind is surely worth more than an inexpensive cup of coffee.【语篇解读】本文是一篇议论文。
