They 1 these clones from a single cell of an adult animal.Recently, a private group of scientists has announced 2 to make an exact copy of a human being. Doctor Zavos, an American member of the team, says he and 3 will soon begin to clone humans and they hope to produce the worlds forst cloned 4 within the next two years.Doctor Zavos says the new 5 group plans to offer human cloning to women unable to become 6 and produce children. The 7 would be similar to that used to clone animals. It would 8 clearing genetic material from a womans egg.

The situation was so severe that there was no time to debate who is to blame. The most 2 (importance) thing for the government to do is to find out the cause of this 3 (dead) disease. They invited all the most famous experts in this field to discuss and quite a few suggestions were 4 (put) forward. Some of the top experts picked out those suggestions and tested them to see whether they were 5 (avail). Doctor Zhong chose one patient who was seriously ill and had little hope of picking 6 and had the new medicine 7 (test) on him. To his great joy, this patient recovered! He made his way 8 his office and telephoned to the top official, 9 (tell) him this exciting news. For convenience, he moved to live in his office. His method 10 make sense. Not soon after that, the other hospitals also controlled this terrible disease and kicked it out finally.1. 2.3. 4.5. 6.7. 8.9. _ 10. _V. 阅读理解AHave you seen Jurassic Park? In this film, scientists use DNA kept for tens of millions of years to clone dinosaurs. They find trouble, however, when they realize that the cloned creatures are smarter and more dangerous than expected. Thats nothing more than a fiction.But could we really clone endangered animals? To date, the most successful attempt to do so was the cloning of a gaur, a rare ox-like animal from southeast Asia. Scientists used a cow to bring the cloned baby gaur, named Noah. Two days after birth, however, Noah died from a common bacterial infection. Other endangered species that may be cloned include the African bongo antelope (邦戈羚羊), the Sumatran tiger, the cheetah (猎豹), and the giant panda.Next, could we really clone extinct animals?In theory? Yes. To do this, you need a well-kept source of DNA from the extinct animals such as wool mammoth (毛象), Tasmanian tiger, or even dinosaur, and a closely related species, still living, which could serve as a surrogate mother.In reality? Probably not. On the one hand, its not likely that extinct animals DNA could survive undamaged for such a long time. Cloning extinct animals as wool mammoth, Tasmanian tiger, or dinosaur is much more difficult due to the lack of properly well-preserved DNA. On the other hand, for example, a gaur can have a cow as a surrogate mother, definitely not a monkey. But what about an extinct animals as unique as the panda? What species could possibly serve as a surrogate mother? Cloning presents many exciting possibilities. However, even if extinct animals are brought back, they could not survive in todays world. Not only do most extinct animals have no habitat to love in, but the other plants and animals they depended on for food may also be gone as well.1. It can be learned from the text that _.A. scientists have cloned the African bongo antelopeB. both the cheetah and the giant panda live in AsiaC. the gaur lives in Asia and is endangeredD. the gaur is an extinct species2. The underlined words “a surrogate mother” probably refer to a female who _.A. contributes its eggs to another female B. gives birth to a baby for another femaleC. gives birth to a baby of its own D. cannot give birth to a baby3. The difficulty in cloning an extinct species is the lack of _.A. both the well-preserved DNA and plants to live onB. both the habitat to live in and the well-preserved DNAC. both habitat to live in and plants to live onD. both the well-preserved DNA and a surrogate mother4. In the authors opinion, it is possible that _.A. some extinct species may be cloned, but not surviveB. extinct species may be cloned and easily surviveC. a gaur can have a monkey as a surrogate motherD. all the extinct species may be clonedBResearch advances over the past decade have told us that, with a little work, we humans can clone just about anything we want, from frogs to monkeys and probably even ourselves!So, we can clone things, but why would we want to?Of all the reasons, cloning for medical purposes most probably benefit large numbers of people. How might cloning be used in medicine? 1. Cloning animal models of diseaseMuch of what researchers learn about human disease comes from studying animal models such as mice. Often, animal models are genetically engineered to carry disease-causing mutations (变异) in their genes. Creating these transgenic(转基因的) animals is a process that requires trial-and-erro and several generations of breeding (培育). Cloning technologies might reduce the time needed to make a transgenic animal model, and the result would be a population of genetically identical animals for study.2. Cloning stem cells (干细胞) for the treatment of diseasesStem cells are the bodys bulding blocks, responsible for developing and repairing the body throughout life. As a result, they might be used to repair damaged or diseased organs and tissues. Researchers are currently looking up cloning as a way to create certain human stem cells for the treatment of diseases.3. Cloning farm animals for drug productionFarm animals such cows, sheep and goats are currently being genetically engineered to produce drugs or proteins that are useful in medicine. Just like creating animal models of disease, cloning might be a faster way to produce large numbers of genetically engineered animals.5. From Purpose One, we can infer that _.A. most transgenic animals are clonedB. most animals carry engineered genesC. most transgenic animal models are not clonedD. most animals carry disease-causing mutations in their genes6. It can be learned from Propose Two that cloning technologies can be mainly used to _.A. create damaged or diseased organs and tissuesB. clone genetically defined human stem cellsC. develop and maintain the body D. repair the body throughout life7. According to Purpose Three, cloning technologies can be mainly used to _.A. speed up the producing of genetically engineered animalsB. produce drugs or proteins that are useful in medicineC. raise genetically engineered cows, sheep and goatsD. produce large herds of animals for human beingsCDifficult times often bring out the best in people. And this was the case for basketball star Yao Ming, who hosted a television show in Shanghai that raised US$300,000 to help researchers find a cure for SARS. Fundraising, or charity, is an act of goodwill towards others. Charities in the West have more flexible ways. Look at a typical day for Ruth, a wealthy woman in the UK, for example. Ruth wakes up in the morning and collects her post. Theres a letter addressed to her with a picture of a half-dead, beaten horse. Its from a charity asking Ruth to donate money to save the animals. The door bell rings and there, on Ruths doorstep, is an old woman asking for money to help the aged. She turns on the television, hears sad music and sees a picture of a wide-eyed child dying of hunger in Africa with an appeal for money to help the child. Ruth then goes shopping for a dress to wear to that evenings large party for the rich and famous. The ticket cost her a small fortune, but she doesnt mind because most of the money is going to a charity that fights AIDS. She feels good about going because shes helping the sick. Within five minutes of walking down the street, Ruth has passed a charity shop. She doesnt stop because she doesnt think shed find a suitable dress thereits full of old, secondhand clothes. But, many other people enter and but all sorts of bargains. Edna, a little old lady, looks after the shop. Any profit it has made goes to a cancer charity. Now that she has retired, she has plenty of spare time to offer her services for free.For people like Yao Ming, Ruth and Edna, charity is a virtue that holds the same importance in life as faith and hope. “As you look back on your life, the moments that stand out are the moments when you have done things for others,” said Scottish author Henry Drummond.8. Which of the following is NOT mentioned in the story as a way of fundraising?A. Charity party B. Charity postC. Charity TV programD. Charity for beggars.9. What does the word “raise” in the first paragraph mean?A. Collect togetherB. DonateC. IncreaseD. Bring to someones attention.10. We can infer from the passage that .A. Yao Ming donated US$300,000 to help researchers find a cure for SARSB. Edna may not be a rich lady but she is willing to do something for othersC. Ruth leads a busy life and she feels very tiredD. Ruth is angry because so many people ask her for money every day11. Whats the writers attitude towards charity?A. The writer thinks its something only people like Ruth can afford to doB. The writer just wants to inform us of the different ways to practice charityC. The writer thinks its a virtue and admires the people who practice itD. The writer doesnt make it clear in the story12. The underlined part in the last paragraph probably means that .A. when you look back sometimes, you need stand outB. when you want to do something for others, you need stand outC. the moment you stand out, you can do something for othersD. what impresses people deeply is what they have done for othersDCHINA and India possess the global might and energy to transform the 21st century economy. What makes the two giants(巨人) especially powerful is that they complement(补充) each others strengths.Technical and managerial skills in both China and India are becoming more important than cheap labor.China will stay the most important place in mass manufacturing(制造业). India is a rising power in software, design, services, and precision(精密) industry.Business exchanges have increased lately between China and India. They are also among the fastest growing economics.The Chinese Ministry of Commerce says China India trade grew seven times between 2000 and 2020, reaching US$ 13.6 billion last year. Many analysts predict ii will hit US$ 30 billion by 2020. This raises a provocative(煽动性的) question: What if the two nations are combined into one giant Chinadia?13. Why are China and India becoming powerful?A. Because the two giants possess the global might and energy and large populations.B. Because China will stay the most important place in mass manufacturing.C. Because India is a rising power in software, design, services, and precision industry.D. Because China and India are able to complement each others strengths.14. What is the purpose of the question in the last paragraph?A. To draw publics attention to China and India.B. To introduce the two giants development to the public.C. To remind the public to watch out Chinadia.D. To be afraid of the development of the two nations.15. What can we learn from tile above chart?A. Indias population is almost the same as Chinas.B. By 2020 Indias will be larger than ChinasC. China bas a larger output than India.D. By 2020 India will be richer than China.VI. 信息匹配下面是一篇应用文及其应用场合的信息，请阅读下列应用文和相关信息，并按照要求匹配信息。请在答题卡上将对应题号的相应选项字母涂黑。首先，请阅读下列广告：A.
