一、什么是利弊分析类作文利弊分析类作文一般是要求考生针对某一事物或话题的两个方面（如利和弊、好处和害处、优点和缺点）进行分析。
命题中一般是要求考生在第一部分描述要论述的中心事物或话题，指出其利弊；在第二部分详细阐述其“利”的一面和“弊”的一面；最后在第三部分得出结论、总结全文或给出建议。
此类作文在近年来的真题中都没有出现过，考生熟悉其写法即可。
例（1995年）SECTION A COMPOSITION［35 MIN ］Nowadays it has become fashionable for college students to take a part-time job in their spare time.Discuss the advantages and disadvantages of this trend.You are to write in three parts.In the first part state clearly your viewpoint on both the advantages and disadvantages.In the second part support your viewpoint with details or examples.In the last part bring what you have written to a natural conclusion with a summary or a suggestion.类型分析：命题中没有指定题目，但明确要求分析兼职工作的利和弊，由此可判断本文应为利弊分析类作文。
二、结构公式陈列第一段——提出观点① 简述要讨论的主题。
② Some people 持肯定态度。
③ Howeverothers持否定态度。
④ In my opinion/From my point of view.主题has both advantages and disadvantages./can be beneficial or harmful.第一段——提出观点先简要描述要讨论的主题，然后指出人们对其利弊的不同看法，之后引出我的看法，即该主题有利有弊。

阐述时要注意客观，利和弊所占篇幅不能过于悬殊。
第三段——总结观点① Through the above analysis/From the fo regoingwe can see clearly that 主题 has positive aspects as well as negative ones.② 提出建议或希望。
第三段——总结观点自然得出结论，再次强调其利弊。
最后提出自己的建议或希望。
