Although they will share the same genetic code, different conditions in the womb and the environment they are exposed to after birth will change some characteristics, including aspects of the dogs appearance and behavior. Experts also warned that cloning animals is extremely unreliable, only successfully resulting in a healthy specimen (样本) in one or two of every hundred attempts, and that making the cloning process reliable would be a “major achievement”. But South Korean firm Sooam Biotech says it has never failed to produce a clone and will guarantee its work. The technique involves taking a single skin cell from the original animal and replicating its DNA to create a manmade embryo (胚胎), which is born after two months gestation (孕育). The company says it has cloned at least 400 dogs around the world, including rescue and police dogs for the South Korean government and dozens of pets for wealthy American owners. The competition, and following creation of Britains first cloned dog, will be filmed and broadcast in a documentary on Channel Four. Sooam Biotech scientist Insung Hwang said, “We can clone any breed, size or shape of dogs and are coming to the UK to offer this process to the owner of one very special dog. We welcome any UKbased dog owner who wants to benefit from this exciting new advance in biotechnology.” Prof Robin LovellBadge, Head of Developmental Genetics at the MRC National Institute for Medical Research, said cloning in dogs can work but warned that it is “not an efficient (高效的) process” and would not create a replica of the original pet.语篇解读:本文是新闻报道。一家韩国公司准备为英国人克隆他们的宠物狗,但科学家对此持谨慎态度。1Why did scientists warn dog owners? ABecause cloned dogs will not live long. BBecause cloned dogs carry certain diseases. CBecause dog cloning may not bring the perfect result.DBecause dog cloning is still too expensive for common people.解析:选C细节理解题。由文章第二段可知,科学家警告狗的主人,原因是克隆来的狗不会和以前的狗一模一样,而且克隆的失败率很高。2What can be inferred from the fifth paragraph?

DInsung Hwang is confident in his cloning work.解析:选D推理判断题。由文章第五段可知,Insung Hwang宣称自己能够克隆各种品种的狗,说明他对自己的工作充满了信心。3What is Robin LovellBadges attitude towards dog cloning? ACautious. BSupportive. CDisapproval. DSubjective.解析:选A推理判断题。分析文章最后一段,Robin LovellBadge还是强调克隆的不可靠,由此推断,他对克隆持有谨慎态度。4What can be the best title for the passage?

Well, generally, it could make couples unable to have babies have their own children.Replacing a dead child is also another reason why some people have expressed interest in the technology.语篇解读:本文是说明文,介绍了克隆的相关情况。5The purpose of the first paragraph is to _.Agive us an introduction to a movieBanalyse the possibility of cloningCgive an introduction to the textDtell us the importance of cloning解析:选C从后文内容可知,第一段主要是为了引出下文。6We can infer from the second paragraph that _.Amore and more people are interested in cloningBcloning has saved many animals from dying outCcloning has a very short historyDcloning plants is much easier解析:选D第二段说明,人们已经成功克隆了植物,而动物还不太成功,说明克隆植物要比克隆动物简单得多。7In what way is human cloning useful?AIt can bring a dead person back to life.BIt makes it possible to replace a dead child.CIt can help cure some human diseases.DIt can help people have more healthy children.解析:选B从最后一段可知,克隆人可以替代一个死了的孩子或者帮助不孕夫妻受孕。8What does the underlined word “misgivings” in the third paragraph mean?AWorries.
