Get to the topic 01 Do you know about cloning 02 Come up with at least three questions about cloning. ...的过程 ①Cloning is the process of making an exact copy of a plant or animal and developing it either naturally or artificially. Natural cloning has been going on for generations. For example, gardeners have been using a form of cloning when they take a cutting from a plant and place it in a 世世代代 例如 go on 发生；进行 要么...要么...；或者…或者… 一种形式 when引导时间状语从句 suitable medium, such as soil. Another example of natural cloning is identical twins, who are produced from the same egg. 相同的 be identical to/with 和……一样/一致 be identical in 在……方面一样/一致 例如 译文： 克隆(clone)是通过自然或人为(artificially)的方式，对植物或动物进行精确复制、培育的过程。自然克隆由来已久。例如，园丁们从植物上截取一段，放在合适的培养基，例如土壤中，就是一种克隆。自然克隆的另一个例子是同(identical)卵双胞胎(twin)，它们是由同一个卵子受精产生的。 ②For years, there had been attempts to clone animals artificially. The first successfully cloned animal was a sheep named Dolly in 1996. At first, Dolly grew normally, but later she developed an illness that is more normally found in much older animals. She lived for six and a half years, 起初 much修饰比较级 患病 attempt to do sth.试图做某事 only half the life of the sheep from which she was cloned. After Dolly, scientists have cloned more than 20 mammal species, including camels, cattle, deer, dogs, goats and mice. However, they have found a similar pattern of health problems with these other species as well. This has led to 超过 lead to 引起 也 “from＋which”引导的定语从句 questions such as, “Will this be a major issue for all cloned animals ” “Will it continue to happen forever ”. 主要问题 continue to do sth.继续做某事 ③In January 2018, the cloning of two long-tailed monkeys, Zhong Zhong and Hua Hua, was announced by Chinese scientists. They were the first-ever primates (the order of mammals which include apes, monkeys, and humans) to have been cloned! In comparison with other species,cloning primates has proved to be “much harder”, and doing so with 前所未有的，史无前例的 与……比较 prove to be被证明是，证明为 non-reproductive cells was even more complicated. Dr. Sun Qiang, director of the research team, said they had been wholly devoted to the research and had been taking care of more than 1,000 monkeys 2 ... ...
