课时提升作业十七必修4Unit 2Working the land(限时35分钟)Ⅰ. 阅读理解A(2018·茂名模拟) If you believe in thermometers(温度计), you should believe in global warming. And if you believe in eating fries with your burger, you should worry more about carbon emissions.It won’t happen overnight, but as the planet’s climate changes, the growth cycles of main crops will all be heavily affected. Here are three of the crops that might not beat the heat.The potato actually needs a great deal of beauty rest to develop properly. “They need a cool nighttime temperature in order to start growing the tuber, the part that we eat, ” Nelson says.Temperature and altitude are two primary concerns in coffee growth, and farmers are stuck between a rock and a hard place. “We know that coffee grows in a certain temperature range, ” Nelson says. “They’vebeen moving up the mountains, but at some point you run out of mountains to move up. ” Higher-grade strains of Arabica coffee in Central American regions are at particular risk due to the need for lower growing temperature, especially since diseases and pests are also becoming more of a factor as temperatures rise.Even if you’re looking at the direct effects of temperature alone, rice is in trouble. “As nighttime temperatures go up, the rice is going to have a problem flowering and won’t make as many seeds, ” Nelson says. In addition to this direct heat consequence, rising sea levels will flood many rice fields and destroy water salinity levels, while droughts will lower production, raise prices, and further shame westerners who are too clumsy with chopsticks to be able to clear their plates once a new grain is adopted.【文章大意】本文主要介绍的是马铃薯、咖啡和水稻这三种农作物需要凉爽的夜间温度才能够生长得好, 如果气温变化太大则不能生存。

This Ms Boyle, looking unfashionable, from a village in Scotland, shocked the three judges and the audience with the song I dreamed a dream from the musical Les Miserables on a show of Britain's Got Talent, one of the hottest reality shows in Britain.She couldn't hide the awkwardness when walking to the center of the stage in a housedress, and everyone—including the judges—seemed laughing at her when she said she wanted to be as successful as Elaine Paige. As soon as she began singing, however, everyone in the auditorium fell silent, then rose within seconds to applaud her incredible voice as the celebrity judges sat open­mouthed, and remained standing to the end.After her performance, one of the judges Piers Morgan said，“Without doubt thatwas the biggest surprise I've had in three years of this show. When you stood there everyone was laughing a t you.No one is laughing now. That was amazing.”Actress Amanda Holden followed，“I'm so thrilled because I know that we everybody were against you.I honestly think that we were all being very cynical(愤世嫉俗的) and I think that's the biggest wake­up call ever.”Susan obviously won over the hearts of millions around the world with sensation spreading across the Atlantic. Hollywood actors Ashton Kutcher and Demi Moore—who between them have nearly 1.5 million followers—speak highly of her. Kutcher posted a link to the video clip(片段). The Scottish talent made her live American debut via satellite connection on CBS's The Early Show, doing an interview and singing live from her room. And she already accepted an invitation from talk show hostess Oprah Winfrey.Now Boyle has become one of the world's hottest celebrities.

Their algebra teacher, LaMar Queen, uses rhyme to help them memorize seemingly difficult items to improve their grades.Queen, 26, is now known at Los Angeles Academy Middle School as the rap teacher, but his fame has spread beyond the 2，200­student school in this neighborhood. He's won a national award and shown teachers and parents how to use rap to teach children.“Math is a bad word for many students, but if we put it in a form that kids enjoy, they'll learn，” Queen said. “Rap is what the kids respond to.They don't have a problem memorizing the songs at all.”Queen's math rap came about by chance. Two months after starting at LA Academy, he was frustrated when kids said his class was boring. They thought that he looked like the singer Kanye West, so they challenged him to rap.Queen has been rapping since the seventh grade. With his students' challenge on his mind, he pushed aside work on his lesson plans and wrote a rap song Slope Intercept.Word of his rapping soon reached the school's main office. Principal Maria Borges went to look into it, and came out smiling.“It interests the kids，” she said.“Kids seem to know all the rap songs, and it's helpful for them to remember math rules.” “Some kids who aren't even in Mr Queen's class go ar ound singing his songs，” said Kejon Closure, 13, who went from a C­average to an A.In the raps, Queen defines a math concept and works through sample problems step by step. He keeps a relaxed manner when singing with his students. Queen also tries to insp ire them. His lyrics tell students “to get As on your papers”，and “to be respectful and listen to your parents”．Sometimes the students appear in the videos as a reward for good grades and behavior.20．According to the passage, LaMar Queen has been ________ since he began to teach students at Los Angeles Academy.A．a popular teacher B．a music teacherC．a mathematics teacher D．a famous singer21．LaMar Queen has won a national award because ________．A．he is good at composing rap songsB．his new musical production was shown on TVC．he created a unique teaching method in mathD．he gave students a lot of confidence22．We can infer from the last paragraph but one that ________．A．Queen's teaching method has been well received by both the principal and the studentsB．Queen makes math easy and tries to inspire his students in the rapC．Queen is willing to help the students who are not good at mathD．Principal Maria Borges doesn't think it a good way to teach math by rapping 23．This passage may be taken from China Daily in the column of ________．A．society B．educationC．entertainment D．biographyⅢ.短文填词Last weekend, our school organized a social activity.

Then her garden gave her the idea for a business: She'd planted 20 bamboo forests on their seven­acre farm.Heinr icher started Boo­Shoot Gardens in 1998. She realized early on what is just now beginning to be known to the rest of the world. It can be used to make fishing poles, skateboards, buildings, furniture, floors, and even clothing. An added bonus: Bamboo absorbs four times as much carbondioxide as a group of hardwood trees and releases 35 percent more oxygen.First she had to find a way to mass­produce the plants—a tough task, since bamboo flowers create seed only once every 50 to 100 years. And dividing a bamboo plant frequently kills it.Heinricher appealed to Randy Burr, a tissue culture expert, to help her.“People kept telling us we'd never figure it out，” says Heinricher.“Others had worked on it for 27 years! I believed in what we were doing, though, so I just kept going.”She was right to feel a sense of urgency. Bamboo forests are being rapidly used up, and a United Nations report showed that even though bamboo is highly renewable,_as many as half of the world's species are threatened with dying out.Heinricher knew that bamboo could make a significant impact on carbon emissions(排放)and world economies, but only if huge numbers could be produced. And that's just what she and Burr figured out after nine years of experiments—a way to grow millions of plants. By placing cuttings in test tubes with salts, vitamins, plant hormones, and seaweed gel, they got the plants to grow and then raised them in soil in greenhouses.Not long after it, Burr's lab hit financial difficulties. Heinricher had no experience running a tissue culture operation, but she wasn't prepared to quit. So she bought the lab.Today Heinricher heads up a profitable multimillion­dollar company, working on species from all over the world and selling them to wholesalers(批发商). “If you want to farm ba mboo, it's hard to do without the young plants, and that's what we have，” she says proudly.11．What was the main problem with planting bamboo widely?A．They didn't have enough young bamboo.B．They were short of money and experience.C．They didn't have a big enough farm to do it.D．They were not understood by other people.12．What does Heinricher think of bamboo?A．Fragile and affordable.B．Productive and flexible.C．Useful and earth­friendly.D．Strong and profitable.13．The underlined word “renewable” in Paragraph 6 probably means “________”．A．able to be replaced naturallyB．able to be raised difficultlyC．able to be shaped easilyD．able to be recycled conveniently14．What do you learn from the passage?A．Heinricher's love for bamboo led to her experiments in the lab.B．Heinricher's determination helped her to succeed in her work.C．Heinricher struggled to prevent bamboo from disappearing.D．Heinricher finally succeeded in realizing her childhood dream.BAll over my garden I've planted nothing but roses, because I especially love the flower.A close friend came for a visit the other day. I told her that she should pick a bunch of roses to beautify her bedroom. I promised that the smell of the roses would be wafted far, far away.That girl friend of mine, walking into the garden in high spirits, smelt here and there, but in the end she didn't pick a single rose. I said that she could pick many flowers; I told her that I was not a flower farmer and didn't make a living out of them. Saying so, I raised the scissors for the sacrifice of the flowers, but she stopped me, crying no, no, no!To cut such beautiful roses would hurt one, she said. With her hands seizing at my sleeves, she told me that by no means should they be cut.

He was coming back with a heavy heart. It was not just that it was the end of a wonderful holiday； it was not just that he invariably suffered badly from jet lag； it was that Monday mornings always began with a team meeting and， over the months， he had grown to hate them.Martin was aware that colleagues approached these meetings with hidden agendas；they indulged(纵容) game－playing； and he knew that people were not being honest and open. The meetings themselves were bad enough—there was all the moaning afterwards at the meeting like “I could have improved on that idea， but I wasn't going to say”.As this morning's meeting began， Martin prepared himself for the usual dullness and boredom. But， as the meeting progressed， he became aware of a strange background noise. At first， he thought that he was still hearing the engine noise from the aircraft that had brought him back to London. But， as he concentrated on the noise，it became a little clearer.He realized—to his amazement—that he could actually hear what they were thinking at the same time as they were speaking. What surprised him， even more than the acquisition(获得) of this strange power， was that he discovered that what people were saying was not really what they were thinking. They were not making clear their reservations. They were not supporting views which they thought might be popular. They were not contributing their new insights. They were not volunteering their new ideas.Martin found it impossible not to respond to his new knowledge. So he started to make gentle interventions， based more on what he could hear his colleagues thinking than on what he could hear them saying. “So，John are you really saying…” “Susan， do you really think that？” “Tom， have you got an idea on how we could take this forward？” They looked at him， puzzled. In truth， he felt rather proudof his_newly－acquired_talent.As the meeting progressed， it was clear to him that each member of the meeting was learning how to hear the thoughts of the others. The game－playing started to fall away； people started to speak more directly； views became better understood；the atmosphere became more open and trusting.The meeting ended. As people left the room， Martin found that he could still hear what they were thinking. “That was the best meeting we've ever had.” “All meetings should be like that.” “In future，I'm going to say what I think”.16．It is known from the first paragraph that Martin ________.A．just came back from his business trip in New YorkB．was found to suffer from a serious heart disease during the tripC．had a good time during his fortnight's stay in New YorkD．didn't like his work in his London office17．Why did Martin hate his company's team meeting？A．Because it had to be held every Monday morning.B．Because he was tired of hosting such a meeting.C．Because he couldn't control the meeting that was out of order.D．Because the meeting atmosphere wasn't open and trusting.18．The underlin ed part “his newly－acquired talent” in Paragraph 5 means that he could ________.A．still hear the engine noise of the plane though he was backB．clearly hear what the members of the meeting were sayingC．actually control the thoughts of the members of the meetingD．express what the meeting members were thinking based on their words and their thoughts19．What do we know about this Monday morning's meeting from the passage？A．Martin made people say what they were thinking immediately the meeting began.B．Martin was angry at the dullness of the meeting at the beginning of the meeting all the time.C．Martin led people to express their real thoughts with the meeting progressing.D．Many members of the meeting played games and told lies at the meeting all the time.20．It is inferred from the last two paragraphs that towards the end of the meeting Martin would hear such words as “ ________”.A．I was thinking of making a suggestion—but I couldn't be botheredB．I have got an idea on how we could take this forwa rd. I think we should…C．The usual people say the usual things， so I have no other new ideas D．I could have improved on that idea， but I wasn't going to sayⅢ.阅读表达阅读下面短文并回答问题，然后将答案写到相应的横线上(请注意问题后的词数要求)。

课时提升作业十七必修4 Unit 2 Working the land(限时35分钟)Ⅰ. 阅读理解A(2018·茂名模拟) If you believe in thermometers(温度计), you should believe in global warming. And if you believe in eating fries with your burger, you should worry more about carbon emissions.It won’t happen overnight, but as the planet’s climate changes, the growth cycles of main crops will all be heavily affected. Here are three of the crops that might not beat the heat.The potato actually needs a great deal of beauty rest to develop properly. “They need a cool nighttime temperature in order to start growing the tuber, the part that we eat, ” Nelson says.Temperature and altitude are two primary concerns in coffee growth, and f armers are stuck between a rock and a hard place. “We know that coffee grows in a certain temperature range, ” Nelson says. “They’ve been moving up the mountains, but at some point you run out of mountains to move up. ”Higher-grade strains of Arabica coffee in Central American regions are at particular risk due to the need for lower growing temperature, especially since diseases and pests are also becoming more of a factor as temperatures rise.Even if you’re looking at the direct effects of temperatu re alone, rice is in trouble. “As nighttime temperatures go up, the rice is going to have a problem flowering and won’t make as many seeds, ” Nelson says. In addition to this direct heat consequence, rising sea levels will flood many rice fields and destroy water salinity levels, while droughts will lower production, raise prices, and further shame westerners who are too clumsy with chopsticks to be able to clear their plates once a new grain is adopted.【文章大意】本文主要介绍的是马铃薯、咖啡和水稻这三种农作物需要凉爽的夜间温度才能够生长得好, 如果气温变化太大则不能生存。
