范文赏析
最近你在某网站有一篇抨击克隆技术的文章，文章作者认为克隆是残忍的，而你并不赞同此观点。请你写一篇英语短文作为评论反对此观点。主要内容包括：1. 你的观点；2. 你的理由。 Cloning has always been a controversial topic since it was brought up. There is no doubt that some people are against it, thinking it’s cruel, but I believe that cloning benefits our society. For example, if a couple can’t have children, cloning can help give them a child. Besides, cloning enables endangered species t increase their population, preventing some species from dying out. What’s more, cloning can be used to find cure for fatal diseases.
In a word, cloning is not cruel at all. On the contrary, it can help us in many aspects. I believe if we make good use of cloning, we can benefit greatly from it.

作文：
I don’t think it’s good to clone human beings. The reasons are as follows. To start with, cloning human will cause moral problems. For example, some people may want to clone the dead, which is unacceptable. What’s more, people may want to clone themselves in the hope that they could live forever, which is also against nature. Frankly, I would shiver at the thought that another “me” was created and lived the same life as I did. As far as I am concerned, it’s better that scientists do not clone human beings. However, we can clone valuable plants or animals for the purpose of medical research and species protection.
