如何写作CET-4提纲作文？
提纲作文是近几年的写作考试中最常见的题型，占历次考试的82%以上。由于有了命题和提纲对整篇文章的主题内容和选材范围进行规范，考生就不容易偏题，因而这种题型更易于检查考生的英语表达能力。考生应根据提纲对文章主题和内容的规定进行拓展，完成全文的写作。在下面的两篇范例中，第一篇根据中文提纲写作的范文，第二篇为根据英文提纲写作的范文，这正是大学英语四级考试提纲作文的两种类型。
Directions: For this part, you are allowed 30 minutes to write a composition entitled “Euthanasia”. You should base your composition on the following outline (given in Chinese). Write no less than 120 words.
1.有的人赞成实行安乐死；
2.有的人反对安乐死合法化；
3.我的看法。
[范文]
Euthanasia
Euthanasia, a way to help patients die peacefully without pain, recently has made the headline frequently. Many people applaud it and argue that euthanasia should be legalized.
As is pointed out, to practise euthanasia can benefit both the patient and his family. To an incurable who is suffering excruciating pains day and night or living "like a vegetable", to be allowed to end his life painlessly is a good release. It is also a big relief of the financial and emotional burden on his family.
However, the legalization of euthanasia may also bring about problems our society has not previously faced. For example, is it wise to end a patient’s life simply because of a mistaken diagnosis? And is it possible that euthanasia could be used for some evil or criminal purposes?
Since the legalization of euthanasia will raise serious moral and social issues, the decision our society makes about euthanasia will undoubtedly have tremendous consequences in society. Therefore, I think, we should be very cautious and take every aspect into consideration before we come to a decision on the legalization of euthanasia.
这是一篇根据汉语提纲完成的议论文。文章引言段开宗明义，指出安乐死近来成为头条话题，许多人认为安乐死应当合法化。第二段，承接上文，从两个方面论证安乐死对病人及其家属都有利。第三段用however将笔锋一转，表明安乐死也可能带来某些问题。最后一段，作者表明态度：在决定安乐死合法化以前，我们应当认真考虑。本文针对安乐死这一热门话题，紧扣提纲展开行文，重点突出，主题明确。文中多用长句，说理透彻明晰。第三段中三个排比问句的使用，加强了文章的气势，令人深思。
我们再看一个例子：
Directions: For this part, you're allowed thirty minutes to write a composition on the topic: Should We Clone Human? You should write at least 120 words and you should base your composition on the outline given below:
1.Some people think that we should clone human because…
2.However, many people disagree because …
3.My view is that…
[范文]
Should We Clone Human?
These days the world is excited by a piece of news that we can clone a sheep now. There are not many technical problems for us to clone human. But should we clone human? People are discussing this question seriously.
Some people think that we should clone human because it is very useful in science. Firstly, by cloning human, people can learn more about genetics. People can know more details of genetic illness; and so people can try to treat them. Secondly, people can clone a person’s apparatus if he needs to change it for a new one. In this way, we can solve the problem of high death rate in apparatus transplantation and we can get enough apparatus to cure the patients. Thirdly, one can clone himself. The new copy is completely the same as oneself, so it can be regarded as the continuance of one's life.
However many people disagree, because there still exist many social problems. They ask the question if one can get another person' s apparatus without any precondition though that person is cloned from him. They think that the cloned person is an independent person that has his own right. For the same reason, they also question if a cloned person can be considered the person he is cloned from. A body can be cloned, but how can we clone a person's soul?
My view is that we should not clone human now. We must consider the social problems carefully. We should not clone human until we find good solutions to them.
这是一篇根据英文提纲完成的议论文。文章首先从人类已经克隆羊切入正题：Should we clone human? 提出问题后，马上进入主体论述部分，列出正方和反方的不同意见。第二段写正方支持克隆人，并用列举法加以证明。第三段交待反方观点，由于存在某些社会问题，他们反对克隆人。最后一段，作者提出了自己的看法，即反对克隆人。他认为在解决存在的社会问题之前不应克隆人。本文议题新颖、思路清晰。首尾呼应，结构严谨。语言流畅，过渡自然。
