This has caused much debate round the world

8、. On the one hand, some scientists point out that if you clone an embryo, you can produce valuable human tissuessuch as bone or lung tissuethat could be used to save human lives. On the other hand, many people, including some scientists, disagree and are afraid that, if mankind toys with nature in t

9、his way, we may be on our way to producing a real-life Frankensteins monster. Cloning is producing an exact copy of a plant or an animal using its cells. The first mammal to be cloned successfully from an adult cell was Dolly the sheep. She was born in 1996 and died in early 2003, at a much younger

10、age than normal. When she was born, many people were worried that cloning would lead to more diseases in the animal world. However, in general the scientists were praised for their wonderful scientific advance. Ian Wilnut, the Scottish scientist who created Dolly, is shocked that some scientists are

11、 now considering cloning human beings. Although he researches cloning, his intention has never been to create copies of humans. Instead, he thinks research efforts should concentrate on creating new tissues and organs that can be used to cure diseases like cancer. However, some people believe that c

12、loning human embryos with the intention of destroying them shows no respect for human life. Even though human cloning is causing a lot of anxiety, it is good news for Faye Wilson, a 41-year-old saleswoman who cannot have a baby. I am anxious to have a child of my own, she says. I dont want to adopt

13、someone elses childif I had the chance, I would have a cloned baby right now. While cloning human embryos is not legal in many countries, some scientists are already pushing ahead with research in order to produce a cloned human baby. Severino Antinori, an Italian physician, has declared that he wan

14、ts to be the first to clone a human being. In China, scientists have focused their efforts on cloning animals, as well as cloned tissues to be used in medical treatment. China has succeeded in producing clones of cows and goats, and continues to research ways in which cloning can benefit mankind.Dea

15、r Editor, I believe that human cloning is wrong. If we toy with nature, we will have to deal with the consequences. Who knows what could happen? Human life would just become a crop to be harvested or a product for sale. The human race is using up Earths natural wealth. We should be having fewer babi

16、es in order to reduce Earths population, not cloning more. I feel sorry for the lady who cannot have a baby, but I would like to point out that there are many children in the world with no parents who would be delighted to have a mother. Pauline CarterDear Editor, I would like to comment on your art

17、icle The perfect copy. I think the scientific advances mentioned in your article are fantastic. I am in complete agreement with human cloning. After all, scientists have been challenging moral ideas for centuries. Why should we stop them now? On a personal note, cloning would totally transform my li

18、fe. Seven years ago, my 10-year-old daughter died of heart failure. She was beautiful, cheerful and bright. I miss her every single day. If I had the chance, I would clone her immediately so that I could be with her again.Colin JakeFirst period Listen and learn: Listen to the wordlist and try to lea

Why should resources be spent on space rather than on conditions and people on Earth? These are questions that

35、, understandably, are very often asked. Perhaps the best answer lies in our genetic makeup(基因构成) as human beings. What drove our ancestors to move from the trees into the plains, and on into all possible areas and environments? The wider the spread of a species, the better its chance of survival. Pe

36、rhaps the best reason for exploring space is this genetic tendency to expand wherever possible.Nearly every successful civilization has explored, because by doing so, any dangers in surrounding areas can be identified and prepared for. Without knowledge, we may be completely destroyed by the danger.

37、 With knowledge, we can lessen its effects. Exploration also allows minerals and other potential (潜在的) resources to be found. Even if we have no immediate need of them, they will perhaps be useful later. Resources may be more than physical possessions. Knowledge or techniques have been acquired thro

38、ugh exploration. The techniques may have medical applications which can improve the length or quality of our lives. We have already benefited from other spin-offs including improvements in earthquake prediction, in satellites for weather forecasting and in communications systems. Even non-stick pans

39、 and mirrored sunglasses are by-products (副产品) of technological developments in the space, the chance to save ourselves might not exist.While many resources are spent on what seems a small return, the exploration of space allows creative, brave and intelligent members of our species to focus on what

40、 may serve to save us. While space may hold many wonders and explanations of how the universe was formed or how it works, it also holds dangers. The danger exists, but knowledge can help human being to survive. Without the ability to reach out across space, the chance to save ourselves might not exi

41、st.While Earth is the only planet known to support life, surely the adaptive ability of humans would allow us to live on other planets. It is true that the lifestyle would be different, but human life and cultures have adapted in the past and surely could in the future.71. Why does the author mentio

42、n the questions in Paragraph1?A. To express his doubts.B. To compare different ideas.C. To introduce points for discussion.D. To describe the conditions on Earth.72. What is the reason for exploring space based on Paragraph2?A. Humans are nature-born to do so.B. Humans have the tendency to fight.C.

43、Humans may find new sources of food.D. Humans dont like to stay in the same place.73. The underlined word “spin-offs” in Paragraph 4 probably refers to_.A. survival chancesB. potential resourcesC. unexpected benefitsD. physical possessions74. What makes it possible for humans to live on other planet

Space exploration has created many wonders.B. Space exploration provided the best value for money.C. Space exploration c

People who are thinking about adopting a dog as a friend for their cats are worried that they will fight. A recent research has f

46、ound a new recipe of success. According to the study, if the cat is adopted before the dog, and if they are introduced when still young (less than 6 months for cats, a year for dogs), it is highly probable that the two pets will get along swimmingly. Two-thirds of the homes interviewed reported a po

47、sitive relationship between their cat and dog.However, it wasnt all sweetness and light. There was a reported coldness between the cat and dog in 25% of the homes, while aggression and fighting were observed in 10% of the homes. One reason for this is probably that some of their body signals were ju

48、st opposite. For example, when a cat turns its head away it signals aggression, while a dog doing the same signals submission.In homes with cats and dogs living peacefully, researchers observed a surprising behaviour. They are learning how to talk each others language. It is a surprise that cats can

49、 learn how to talk dog, and dogs can learn how to talk Cat.Whats interesting is that both cats and dogs have appeared to develop their intelligence. They can learn to read each others body signals, suggesting that the two may have more in common than was preciously suspected. Once familiar with each

50、 others presence and body language, cats and dogs can play together, greet each other nose to nose, and enjoy sleeping together in the sofa. They can easily share the same water bowl and in some cases groom(梳理) each other.The significance of this research on cats and dogs may go beyond pets-to peopl

51、e who dont get along, including neighbors, colleagues at work, and even world superpowers. If cats and dogs can learn to get along, surely people have a good chance.31. The underlined word swimmingly in paragraph1 is closest in meaning to_.A. early B. sweetly C. quickly D. smoothly32. Some cats and

52、dogs may fight when _.A. they are cold to each other B. they look away from each otherC. they misunderstand each others signalsD. they are introduced at an early age33. What is found surprising about cats and dogs?A. They eat and sleep togetherB. They observe each others behaviorsC. They learn to sp

53、eak each others languageD. They know something from each others voice34. It is suggested in paragraph 4 that cats and dogs_.A. have common interests B. are less different than was thoughtC. have a common body languageD. are less intelligent than was expected35. What can we human beings learn from ca

54、ts and dogs?A. We should learn to live in harmonyB. We should knows more about animalsC. We should live in peace with animalsD. We should learn more body languagesForth periodProject 1: Man versus nature For a long time, our environment has been damaged because humans have been careless. People have

55、 harmed nature through agriculture, fishing, hunting and tourism. We further damage Earth by building new channels in the sea and factories on the land, and by creating pollution with chemical waste. We will some day destroy the planet we live on if we continue in this way.However, if we focus only

56、on conservation, then people may suffer. Not everything that is best for nature is good for people. Would anyone say that development should be stopped in favor of nature? From the point of view of some people, we are only doing what humans have always done, using nature to meet our own needs. Other people argue that such thinking may cause a catastrophe, unless
