There are different types of cloning however, and cloning technologies can be used for other purposes besides producing the genetic twin of another organism.Scientists have been cloning animals for many years. In 1952, the first animal, a tadpole, was cloned. Before the creation of Dolly, the first mammal cloned from the cell of an adult animal, clones were created from embryonic cells. Since Dolly, researchers have cloned a number of large and small animals including sheep, goats, cows, mice, pigs ,cats, rabbits, and a gaur.

Now middle-aged Americans may not keep in touch with old people until they are old themselves.That's because we group people by age. We put our three-year-olds together in day-care centers, our 13-year-olds in schools and sport activities, and our 80-year-olds in senior citizen homes. Why?We live far away from the old for many reasons. Young people sometimes avoid the old to get rid of fears of becoming old and dying. It is much harder to watch someone we love disappear before our eyes. Sometimes it’s got hard that we stay away from the people who need us the most.Fortunately, some of us have found our way to the old. And we have discovered that they often save the young.A reporter moved her family into a block filled with old people. At first her childrenwere disappointed. But the reporter made banana bread for the neighbors and had her children send it and visit them. Soon the children had many new friends, with whom they shared food, stories and projects. "My children have never been lonely, "the reporter said.The young, in turn, save the old. Once I was in a rest home (an organization where old people are cared for) when a visitor showed up with a baby, she was immediately surrounded. People who hadn't gotten out of bed in a week suddenly were ringing for a wheelchair. Even those who had seemed asleep woke up to watch the child. Babies have an astonishing power to comfort and cure.Grandparents are a special case. They give their grandchildren a feeling of security and continuity. As my husband put it "My grandparents gave me a deep sense that things would turn out right in the end." Grandchildren speak of attention they don't get from worried parents. "My parents were always telling me to hurry up, and my grandparents told me to slow down," one friend said. A teacher told me she can tell which pupils have relationships with grandparents: they are quieter, calmer and more trusting.46. Now in an American family, people can find that___________.A. children never live with their parentsB. not all working people live with their parentsC. old people are supported by their grandchildrenD. grandchildren are supported by their grandparents47. Seeing a baby, the old people got excited because _______.A. they had never seen a baby beforeB. the baby was clever and beautifulC. the baby brought them the image oflifeD. the baby's mother would take care of them48. Why are some children quieter, calmer and more trusting ?A. Because they have relationships with their grandparents.B. Because their worried parents ask them to act like that.C . Because they have nothing to worry about.D. Because their teachers ask them to act like that.49. Which of the following can show the fact that the old often save the young?A. The old can become friends of the children and the children may not feel lonely.B. The old get excited when they see a baby. 高@考☆资&源*网C. The old can cure the young when they are sick.D. Babies have an astonishing power to comfort and cure.B篇The other day I heard a few local musicians talking:"I hate all the pianos in this town and I hate that rubbish they play on the radio. They cannot even understand rhythm (韵律).""Nobody wants to pay musicians anything. I’m sick of all the people who want you to play without paying you."One younger musician said, "There are several clubs who want me to play for a few nights a month, and I’m trying to find other places to play. I’m also planning to join in several summer festivals this year."I really liked what the younger musician said so I made friends with him.Attitudes are im portant. Whether they’re positive (积极的) or negative (消极的), they’re all rubbing off on you. If you’re around people who are always complaining or blaming (责备) others, it is possible that you will start doing the same as well. If you spend lots of time with people who don’t support (支持) yourdreams, it is time to take a look at the people you call "friends".There is an easy exercise you can try. Make a list of the people who you often stay with, and simply stop spending time with the negative ones on your list. Set a new standard for yourself and don’t become friends with people who fall below that standard.Of course, this exercise is entirely different from making friends only for the good of oneself. We really should try to help and spend time with those who are working towards a goal or dream.50.The musicians’ conversation at the beginning is there to show that ______.A. musicians’ living conditions are not goodB. people in that town have poor taste in musicC. young people are more likely to succeedD. different people have different attitudes51.The underlined part "they’re all rubbing off on you" in Paragraph 6 means ______.A. they’ll push you aheadB. they’ll help you realize your dreamsC. they’ll keep you from moving onD. they’ll have an influence (影响) on you52.By doing the exercise mentioned in Paragraph 7, you can ______.A. improve your ability to make friendsB. make the right kind of friendsC. develop a better relationship with your friendsD. make some new friends with the same interests as you53. We can get the following information from the passage EXCEPT ______.A. the younger musician is a positive person and would be a good friendB. one should avoid (避免) making friends with people who have lots of difficultiesC. the exercise can help you keep close to really helpful friendsD. one will start complaining if one spends too much time with negative people .1-5.BDCBC6-10.DCABC11-15.CAACB 16-20.ACCBC21-25.BABAB26—45 CCADD CBDDD CDBDC BBDDC 46-53 BCAA DDCB。
