He is often described as the man who has saved more lives than any other person in history. Norman Borlaug is considered the father of what has been called the Green Revolution. His ideas about agriculture increased crop production and ended hunger in many nations. Mr Borlaug continues to be a leader among agricultural researchers.Norman Borlaug was born in 1914 on a farm in the American state of Iowa. In the middle of the 20th century, world population was expanding faster than food production. Experts said many people in developing countries would face starvation.Norman Borlaug was an agricultural researcher at the International Maize and Wheat Improvement Center in Mexico. He developed methods of growing wheat that increased the amount harvested by three times. He later repeated this success in India, Pakistan and Africa.His methods of farming saved millions of people who would have starved to death. Norman Borlaug was given the Nobel Peace Prize for his efforts in 1970.Norman Borlaug is still urging experts to think about the needs of people around the world. His latest concern is a disease in wheat called UG 99.He says it has the power to destroy mostof the wheat being grown around the world. He says reductions in agricultural programs have made it harder to take action against such threats.Mr Borlaug's granddaughter Julie works at the center named after him at Texas A&M University in Dallas. She says his worry about food problems rises from the belief that hunger is unacceptable. She says Norman Borlaug still believes it is our responsibility as human beings to feed one another.11. Norman Borlaug was ________ years old when he was given the Nobel Prize.A．56 B．94C．65 D．9912．In the passage, the writer tries to ________.A．express his respect for Norman BorlaugB．introduce Norman Borlaug's own life in AmericaC．show an interest in Norman Borlaug's researchD．describe Norman Borlaug and his research13．Which of the following statements about UG 99 is true?A．UG 99 is a modern software virus.B．UG 99 is a disease that does great harm to the wheat.C．UG 99 is a virus that appeared in 1999.D．UG 99 caused increase in agricultural output.14．In this passage, the author did NOT mention ________ besides the USA.A．France B．PakistanC．India D．Africa15．From the passage we can infer that________.A．Mr Borlaug died in 1970B．Norman Borlaug has made great contributions to the crop productionC．it is easy to take action against such threatsD．hunger is the main problem in AsiaBSome disabled people use a special card when they park their cars. These are called disabled placards, which are removable signs that can be hung from the rear－view(后视) mirror of a car. These placards are only supposed to be for disabled people.These placards are meant to help disabled people in a number of ways. They allow the person to park in special parking spaces. They can also be used when disabled people are being dropped off or picked up. Disabled people can even use them to park without having to pay.Parking officials think that some people are cheating. Not all people who have these placards are disabled. Today, one in sixteen drivers in California carries the sign. There are a lot more people who have disabled placards today than ten years ago. An official from the DMV(加州车辆管理局) says that there are many reasons for the increase. As people get older, they may develop health problems and need to have one. There are also other reasons why more drivers have them today. Finally, there are a number of people who have them that should not.Last year the DMV cancelled more than 25,000 permits. They found that lots of people who had the disabled placards had died. These permits are no longer valid.Some people are worried that the system is being abused. They are worried that access to the program could be limited because of the misuse. More rules could make it harder for people with real disabilities to get these placards.16．What do we know about placards?A．They are all used by disabled people.B．They are cards designed by disabled people.C．They can help disabled people park their cars.D．They allow disabled people to drive anywhere.17．The DMV cancelled many permits because________.A．the number of old people is growingB．the number of disabled people is on the riseC．they want to make it harder for disabled people to get themD．some people who have the placards have died18．What can people do with the placards?A．When disabled people are being dropped off, they can be used.B．Disabled people can pay for parking with them.C．Drivers can use them to drive their cars.D．People can have access to DMV with them.19．What does the third paragraph mainly talk about?A．The reasons why disabled placards are also popular among drivers.B．Some healthy people also use the disabled placards.C．The number of disabled placard users had increased.D．More reasons for drivers to use car cards.20．We learn from the passage that________.A. disabled placards will be stopped by the governmentB．some people will be punished for breaking the lawC．some disabled people will be forbidden to use disabled placardsD．some rules will be made related to disabled placardsⅢ.读写任务阅读下面的短文，然后按照要求写一篇150词左右的英语短文。

Unit 2 Working the landⅠ.阅读理解A体裁：说明文话题：农业词数：375 时间：6′Organic farming is a big－picture exercise.It's not only targeted at this season's results，but considers future generations.In the long run it makes better economic sense as well.But its main goal is to contribute to a healthier world.Studies conducted all over the world have shown the effects that conventional chemical farming has on the environment.Certainly，chemical fertilizers，pesticides，and herbicides increase the quantity of a farm's production.They help produce more grains and vegetables.But at what cost? A Swiss study showed that organic farming produces an average of 20% less than conventional methods.But the organically grown food contained 50% less fertilizer and 97% less pesticides.Though only a part of the amount of pesticides a farm uses actually does the job of killing bugs，all of it remains active in the soil for months or even years after application.Perhaps worse，each generation of pests is growing increasingly immune (免疫的)to the chemicals used.It's not even all about the food and the soil.The pesticides used in conventional agriculture are finally spilling their chemical residues(化学残留) into the waterways.It affects wildlife，soil and ecosystems as a whole.According to a Worldwatch paper，Deep Trouble: The Hidden Threat of Groundwater Pollution，poisonous chemicals are polluting groundwater on every inhabited continent，endangering the world's most valuable supplies of freshwater.Perhaps not so intuitive，organic farming affects the air.“Organic agriculture can reduce greenhouse gas emissions by effectively locking more carbon into the soil rather than releasing it into the atmosphere，” found “Farming Systems Trial，”a 15－year anic agriculture even uses 50% less energy than conventional farming.How does organic farming deal with pests? Organic farmers intentionally buildup populations of beneficial insects，such as ladybugs(瓢虫)，that eat other pests and control the growth of insects.Wildflowers create green belts that control the spread of weeds and themselves encourage the beneficial insects.Farmers have to stick to strict standards and practices to earn the label “organic.” Looking forward，by promoting biological diversity and maintaining soil fertility，organic farming creates a natural balance that helps to get high quality food in healthy quantities year after year.1．Which of the following can be the best title for the passage?A．The best ways to set up organic farmingB．Why organic farming benefits the environmentC．The history and development of organic farmingD．How to deal with pests and chemical residues答案 B [主旨大意题。

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 that was the biggest surprise I've had in three years of this show. When you stood there everyone was laughing at one is laughing now. That was amazing.”Actress Amanda Holden followed，“I'm so thrilled because I know that we everybody wereagainst honestly think that we were all being very cynical(愤世嫉俗的) and Ithink 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 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 aninterview and singing live from her room.

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. Roses are the smiling face of the earth, and who could be so iron­hearted as to destroy such a charming smile?My mind was shocked: the ugly earth, the tough earth, the plain earth—it is for the reason of that smile that it wins the care and pity of people.15．The writer plants nothing but roses in her garden probably because ________.A．she can make money out of themB．her friends like themC．she enjoys the roses very muchD．the roses sell well16．The underlined word “wafted” in Paragraph 1 is closest in meaning to “________”．A．given off B．lostC．destroyed D．thrown away17．Why did the writer's close friend refuse to pick a single rose?A．Because the roses were not beautiful.B．Because she loved the roses very much.C．Because she did not like this kind of roses.D．Because the writer did not want to give her any.18．What is the best title for the passage?A．The Pity of People to the RosesB．A Lover of FlowersC．A Lovely Rose GardenD．The Smiling Face of the EarthⅢ.完成句子阅读下列各小题，根据每句后的汉语提示，用句末括号内的英语单词完成句子。
