10、 In the past, scientists have produced exact genetic copies of sheep and a few other animals. 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 th

11、e team, says he and 3 will soon begin to clone humans and they hope to produce the world’s 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

12、 clone animals. It would 8 clearing genetic material from a woman’s egg. Doctors then would 9 genetic material from the woman’s husband into the egg 10 putting it in the women’s uterus(子宮). Doctor Zavos says his 11 plans to do its work in a country near the Mediterranean Sea, but he di

20、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 o

21、f 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

24、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. That’s nothing more than a fiction. But could we really clone endangered animals?

25、 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

26、cloned include the African bongo antelope (邦戈羚羊), the Sumatran tiger, the cheetah (獵豹), 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

27、 even dinosaur, and a closely related species, still living, which could serve as a surrogate mother. In reality? Probably not. On the one hand, it’s not likely that extinct animals’ DNA could survive undamaged for such a long time. Cloning extinct animals as wool mammoth, Tasmanian tiger, or

28、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?

29、 Cloning presents many exciting possibilities. However, even if extinct animals are brought back, they could not survive in today’s 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

30、 learned from the text that ________. A. scientists have cloned the African bongo antelope B. both the cheetah and the giant panda live in Asia C. the gaur lives in Asia and is endangered D. the gaur is an extinct species 2. The underlined words “a surrogate mother” probably refer to a female w

31、ho ______. A. contributes its eggs to another female B. gives birth to a baby for another female C. gives birth to a baby of its own D. cannot give birth to a baby 3. The difficulty in cloning an extinct species is the lack of ______. A. both the well-preserved DNA and plants to l

32、ive on B. both the habitat to live in and the well-preserved DNA C. both habitat to live in and plants to live on D. both the well-preserved DNA and a surrogate mother 4. In the author’s opinion, it is possible that ______. A. some extinct species may be cloned, but not survive B. ex

33、tinct species may be cloned and easily survive C. a gaur can have a monkey as a surrogate mother D. all the extinct species may be cloned B Research 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

34、 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 disease Much of what researchers learn about human

35、disease comes from studying animal models such as mice. Often, animal models are genetically engineered to carry disease-causing mutations (變異) in their genes. Creating these transgenic(轉(zhuǎn)基因的) animals is a process that requires trial-and-erro and several generations of breeding (培育). Cloning technolo

36、gies 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 (干細(xì)胞) for the treatment of diseases Stem cells are the body’s bulding blocks, responsible for developing and repairing the bod

37、y 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 production Farm animals such cows, sheep an

38、d 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. m

39、ost transgenic animals are cloned B. most animals carry engineered genes C. most transgenic animal models are not cloned D. most animals carry disease-causing mutations in their genes 6. It can be learned from Propose Two that cloning technologies can be mainly used to _____. A. crea

40、te damaged or diseased organs and tissues B. clone genetically defined human stem cells C. develop and maintain the body D. repair the body throughout life 7. According to Purpose Three, cloning technologies can be mainly used to ______. A. speed up the producing of genetically engineer

41、ed animals B. produce drugs or proteins that are useful in medicine C. raise genetically engineered cows, sheep and goats D. produce large herds of animals for human beings C Difficult times often bring out the best in people. And this was the case for basketball star Yao Ming, who hoste

42、d 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

43、morning and collects her post. There’s a letter addressed to her with a picture of a half-dead, beaten horse. It’s from a charity asking Ruth to donate money to save the animals. The door bell rings and there, on Ruth’s doorstep, is an old woman asking for money to help the aged. She turns on the te

44、levision, 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 evening’s large party for the rich and famous. The ticket cost her a small fortune, but she doesn’t mind because

45、 most of the money is going to a charity that fights AIDS. She feels good about going because she’s helping the sick. Within five minutes of walking down the street, Ruth has passed a charity shop. She doesn’t stop because she doesn’t think she’d find a suitable dress there—it’s full of old, secondh

46、and 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, ch

47、arity 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 fund

48、raising? A. Charity party B. Charity post C. Charity TV program D. Charity for beggars. 9. What does the word “raise” in the first paragraph mean? A. Collect together B. Donate C. Increase D. Bring to someone’s attention. 10. We can infer from the passage th

49、at . A. Yao Ming donated US$300,000 to help researchers find a cure for SARS B. Edna may not be a rich lady but she is willing to do something for others C. Ruth leads a busy life and she feels very tired D. Ruth is angry because so many people ask her for money every day 11.

50、What’s the writer’s attitude towards charity? A. The writer thinks it’s something only people like Ruth can afford to do B. The writer just wants to inform us of the different ways to practice charity C. The writer thinks it’s a virtue and admires the people who practice it D. The wr

51、iter doesn’t make it clear in the story 12. The underlined part in the last paragraph probably means that . A. when you look back sometimes, you need stand out B. when you want to do something for others, you need stand out C. the moment you stand out, you can do something for othe

52、rs D. what impresses people deeply is what they have done for others D CHINA 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(補(bǔ)充) each other's strengths. Technical and managerial skil

53、ls in both China and India are becoming more important than cheap labor. China will stay the most important place in mass manufacturing(制造業(yè)). India is a rising power in software, design, services, and precision(精密) industry. Business exchanges have increased lately between China and India. They ar

54、e also among the fastest growing economics. The Chinese Ministry of Commerce says China India trade grew seven times between 2000 and 2004, reaching US$ 13.6 billion last year. Many analysts predict ii will hit US$ 30 billion by 2010. This raises a provocative(煽動(dòng)性的) question: What if the two nation

55、s 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 powe

56、r in software, design, services, and precision industry. D. Because China and India are able to complement each other's strengths. 14. What is the purpose of the question in the last paragraph? A. To draw public's attention to China and India. B. To introduce the two giants' development to the

57、 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. India's population is almost the same as China's. B. By 2010 India's will be larger than China's C. China bas a larger output than

58、 India. D. By 2010 India will be richer than China.
