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.2Cloning stem cells (干細(xì)胞) for research Stem cells are the bodys bulding blocks which might be used to repair damaged or diseased organs and tissues. Researchers are currently looking toward cloning as a way to create genetically defined human stem cells for research and medical purposes.3Reviving endangered or extinct speciesDinosaur was an extinct species. Could we really clone dinosaurs? In theory? Yes. What would you need to do this? A wellpreserved source of DNA from the extinct dinosaur, and a closely related species, currently living, that could serve as a surrogate(代用的 ) mother. In reality? Probably not. Its not likely that dinosaur DNA could survive undamaged for such a long time. However, scientists have tried to clone species that became extinct more recently, using DNA from wellpreserved tissue samples.4Cloning humansWhy would anyone want to clone humans？Some reasons are to help infertile_couples have children or to replace a decreased child.However, there are the risks involved.For example，how sure can we be that a cloned baby will be healthy or what might go wrong?【語篇解讀】 為什么要研究克隆技術(shù)？它對(duì)人類有利的方面是什么？1Whats the main idea of the whole passage?AWhy people use cloning.BHow to clone animals.CCloning is of great use for people and animals.DThe development of cloning.解析主旨大意題。由第一段可知。答案A2Which of the following is TRUE according to the passage?ACloning is mainly used for cloning human beings.BIn the far future, we will have the live dinosaurs on earth.CCloning human beings may cause a lot of trouble.DGenetically human stem cells are used for cloning human beings.解析細(xì)節(jié)理解題。由最后一段最后兩句可知。答案C3The underlined phrase “infertile couples” in the last paragraph probably means_.Acouples who just marriedBcouples who are unable to bear childrenCcouples who dont like bearing childrenDcouples who want to bear more children解析推理判斷題。沒有生育能力的父母會(huì)想到用克隆的方法擁有自己的孩子。答案B4According to the passage，the reason why people want to clone humans is that_.Ait can make people live longerBit can help infertile couples have childrenCit can replace a deceased child for the coupleDB and C解析細(xì)節(jié)理解題。由最后一段第二句可知。答案DBThe Human Genome(基因組) Project, a great $3 billion, 15year task aimed at drawing the genetic(遺傳的) map of humans, is now more than 90 percent completed. The scientific and medical communities(團(tuán)體) are very excited about the chances genetic research provides for getting rid of diseases and prolonging(延長) human life. But those communities and policy(政策) makers also are careful about the scientific door they are opening as the project uncovers the mysteries of life.For the last few years, the genetic advances in the developing field of biotechnology(生物技術(shù)) have provides material for all kinds of work, but the developments of modern science in unlocking the secrets of the human genetic code(密碼) have opened a world of possibilities for human health, as well as for the popular imagination.While European and Japanese researchers are making rapid progress in decoding(解碼) human DNA, the leading organization for genetic research is in the United States, which began in 1990, is “unlocking the code” of the human body to learn how to defeat fatal(致命的)diseases. Already, the Human Genome Project has become widely known and praised for finding the genes(基因) connected with terrible diseases as yet(迄今), and making progress toward separating the genes that show a sign of breast cancer or AIDS.Once these genes are found and studied, researchers can develop new ways to attack infections(傳染), and genetic diseases. Medical companies are very interested in mapping the human genome, as they expect to develop a lot of new drugs for these illnesses.【語篇解讀】 繪制人類基因組圖，這將意味著人類消滅癌癥、艾滋病的危害，延長人類壽命將成為現(xiàn)實(shí)。5Why did the scientists work hard at mapping the human genome?ABecause the human genome can destroy many illnesses.BBecause the human genomes completion can help them get rid of many diseases.CBecause they wanted to be better known than others.DBecause the human genome can provide a lot of chances of work.解析語義理解題。從文章最后一段第一句話Once these genes are found and studied, researchers can develop new ways to attack infections(傳染), and genetic diseases 可以看出科學(xué)家們完成人類基因組圖的目的。答案B6Which country studied the genes most rapidly in the world?AJapan. BGermany.CThe United States. DChina.解析細(xì)節(jié)理解題。因?yàn)?the leading organization for genetic research is in the United States，所以選C。答案C7Which of the following is NOT true?AIf the genes can be found, scientists can study many new ways to cure illnesses.BThe scientists have made great progress in connecting the genes with the cancers.CMany medical companies show great interest in drawing the human genome map.DThe United States began the Genes Study early in the 19th century.解析推理判斷題。美國是在 1990 年，即 20 世紀(jì)末開始繪制人類基因組圖的，所以選D。答案D8The author suggests that the Human Genome Project can cause_.Athe policy makers to feel very worried and carefulBthe scientists to work harderCmany people to find work easilyDa lot of companies to produce many new drugs解析推理判斷題。從文章內(nèi)容可知，人類基因組圖的完成將有助于科學(xué)家們攻克一系列難關(guān)。所以，他們?cè)诟Φ靥骄?。答案B
