选修8 Unit 2 Cloning克隆晨读·记忆Be Careful about CloningAfter a series of initial experiments and corrections, the scientist’s hard work paid off when the twin clone turkeys were hatched with normal feather and claws. This breakthrough possibly enabled people to bring their adored pets back to life. However, it bothered him from time to time that their health was in poor condition because they were unable toresist illnesses. This drawback cast him down. Merely 2 weeks later, the clones and their carrier died, which struck frustration into his heart. He retired before he attained his ambition and became a member of an opera chorus to relieve his depression.Shortlyafterwards, the media published a conservative argument objecting to cloning owing to moral problems, and suggested the constitution include compulsory regulations to forbid obtaining commercial profits from cloning.When interviewed, the scientist stared at the decorations on the ceiling, thinking for a while, and then said, “I’m not in favour of any arbitrary assumption, but undertaking cloning does differ from the straightforward procedure of making loafs out of flour. Until we accumulate enough exact knowledge, any practice is in vain and is bound to fail. Altogether, being more careful is reasonable or we may walk into a side road.”谨慎对待克隆在最初一系列的实验和修正之后，科学家的辛苦工作终于取得了成功，一对双生的克隆火鸡孵化出来，羽毛和爪子都很正常.这一突破或许能让人们使他们喜爱的宠物死而复生.然而，使他不时地烦恼的是，因为它们无法抵抗疾病，使得它们的健康状况极差.这个缺点让他很沮丧.仅仅过了两个星期，克隆体和母体都死亡了，这使他内心里充满了挫折，他也因此在达到自己目标前就退休了，并选择加入歌剧合唱团来减轻消沉的感觉.之后不久，媒体就因为道德问题而发表了反对克隆的保守论点，并且建议宪法应该包括强制性的法规禁止通过克隆获得商业利益.当被采访时，科学家盯着天花板上的装饰物思考了一会儿，说：“我不赞成任何任意的假设，但是从事克隆与用面粉制作面包的简单过程确实不大相同.在我们积累了足够的准确知识前，任何实际操作都是徒劳无功的，注定会失败.总而言之，更加谨慎地对待克隆是合理的，否则我们或许会误入歧途.”I.单词盘点1.___________(vi.) 不同；相异→__________(adj.) 不同的II.短语回顾1.得到好结果；取得成功；偿清__________________2.沮丧；不愉快__________________3.赞成；支持__________________4.一定或注定(做)…… __________________5.使……刻骨铭心__________________6.不时；偶尔__________________7.使复生；使复活__________________8.白费力气；枉费心机__________________III.句式扫描1.The fact that she seemed to develop normally was very encouraging.(教材P11)看来多莉是在正常地成长着，这很令人鼓舞.2.Then came the disturbing news that Dolly had become seriously ill. 接着传来了多莉病重的坏消息.3.The advantage is that if there is a new illness some of these animals may die, but others will survive and pass on the ability to resist thatdisease to the next generation.其优点是如果发生某种新的疾病，这类动物中的一些可能会死掉，但是另外一些却能存活下来，并且把这种免疫力传给下一代. 4.Based on what we know now, you cannot clone animals that have been extinct longer than 10,000 years.就我们现在所知，你不可能克隆那些绝种了一万年以上的动物.IV .小试牛刀Ⅰ.单词填空1.At last ，his hard working earned him a lot after he__________(retire)．st night ，the earthquake___________(strike) the place ，making much damage.3.It is _______________(forbid) to sell alcohol to those under the age of 18 here.4.At that moment ，I couldn't say anything____________(owe)to my sadness.5.They were asked to______________(regular)the traffic.6.I'm sorry to have______________(bother) you with so many questions on such an occasion.

Unit 2 Cloning李仕才***阅读理解。
Susan Brownell Anthony was a lady ahead of her time. She fought for women’s rights long before they became a popular issue.Susan was born on February 15, 1820, in Adams，Massachusetts. At that time, women had few rights. They could not own property. Money earned by a married woman belonged to her husband. Major decisions regarding children were made by the fathers. Women could not vote.At the age of 15, Susan became a schoolteacher. She taught for 15 years. Then she began organizing women’s groups to promote causes that were important to women. She helped gain better educational rights for women. She helped give married women possession of their earnings.After the Civil War, Susan became very involved in the women’s suffrage movement. After years of lecturing, writing, and appealing by Susan and other women, some parts of the United States changed their laws to give women the right to vote. The first state was Wyoming in 1869. Other areas and states gradually followed Wyoming’s decision. It was not until 1920 that the U．S. Constitution was changed to give all women voting rights.Susan Brownell Anthony died in 1906 at the age of 86. She was elected to the Hall of Fame for Great Americans in 1950. She was the first American woman to have a likeness(肖像) of her face on a coin. It was the 1979 Susan Brownell Anthony dollar.【解题导语】本文主要介绍了美国历史上著名的女权运动领袖Susan Brownell Anthony。

针对这一技术，有人支持，有人却反对。
根据下面的表格，用英语写一篇文章，并阐述自己的态度和看法。
佳作欣赏Science is developing so fast that it is beyond our imagination.Cloning is one of the most advanced technologies.Is it good or bad？Different people have different opinions.Some people are in favour of cloning technology.They think the technology is of great benefit.Firstly，it can be used to produce valuable tissues and organs that could be used to cure diseases like cancer.Secondly，it can help those who are unable to have a baby but want a baby genetically related to themselves.Besides，it can help those who want to clone their dead relatives.However，a few people object to it.They believe cloning shows no respect for human life，and human life would no longer be unique.More seriously，it would create more diseases in the animal world and cause Earth’s population to increase fast.In my opinion，although the technique is beneficial to mankind in many aspects，cloning human beings will be at the cost of the existence of mankind itself.名师点睛本文第一段提出话题，第二段说明克隆的优点，第三段是克隆的缺点，第四段是表述作者自己的观点。
