List the reasons

Step1 Warm up
If you were offered a chance to clone yourself, would you like to do so?
Step2 Pre-writing DISCUSSION: What’s your opinion on cloning?

S1: No, indeed. 1 know it's a bird like the Great Auk but neither of them could fly. So if you kept either, it wouldn't escape from a park, a family or its home in the wild. You could also farm a dodo, unlike all the others, and produce many of them as exotic pets.

Actually, cloning is a phenomenon that occurs naturally in a wide variety of species. Whenever you see a pair of identical twins, they are examples of nature’s clones. Although scientists have been cloning certain plants like the carrot quite successfully for decades, attempts at cloning animals have not been as successful. However, they began long before the birth of Dolly, the sheep—the first mammal to be successfully cloned.

人们时不时的建议说：可以通过克隆技术让有些已 经灭绝的动物复活，比如恐龙。今天，高二十八班就 是否支持克隆恐龙展开了一次讨论。 有的同学支持克 隆恐龙,因为他们认为：如果恐龙能克隆成功将会给我 们带来很多刺激的体验。我们可以用恐龙来拍电影， 也可以把恐龙养在动物园供人们参观。更重要的是， 可以增加生物种类的多样性。然而，另外一些同学则 持反对的观点。他们认为在一方面，如果恐龙失控的 话将会给人类带来很大的灾难。在另外一方面，让恐 龙没有自己的栖息地而养在动物园对它们很不公平。 对它们是一种惩罚，而不是自由。
