作文练习：今天作文讲正反观点对比型议论文的写作。

本类文章的一般结构为：
第一段：正方观点。
第二段：反方观点。
第三段：我的观点。

评论性议论文只是客观的分析和评论某一事物的正反两个方面，或在某一问题上反映出来的两种不同看法，并不下结论说其对或不对，正确或错误。这类作文主要适用于评论那些难以绝对说好或不好的主题，这时四级考试中经常出现的题目。

这类作文要求在比较所讨论的两个事物的优缺点时，要有自己的观点倾向。对自己赞同的事物，其有点要多写祥写，而对其略点要少写略写。对反对的事物其有点要少写略写，一笔带过，而对其缺点则要多写祥写。最后在我的观点中对以上对比加以总结，明确表达自己的观点看法。

范文背诵：

Reading Selectively Or Extensively?
Outline:
1. 有人认为读书要有选择
2. 有人认为应当博览群书
3. 我的想法

How should we read? Should we read selectively or extensively? Everyone has his own view. Some people think we should read selectively. They argue that with the development of modern science and technology, more and more books are published. It is impossible for us to read all the books. What’s more, there are many bad books that are poisonous to our mind, and we shouldn’t read them. Since we can’t read all the books and we shouldn’t read bad books, we must read selectively.

But others may not agree, they emphasize that today's society is not what it was. If one man has many kinds of knowledge, he will have more chances to succeed. If a man knows much in one field but knows nothing in other fields, he may be useless. Since we must have many kinds of knowledge, we must read extensively.

Who’s right? I think both of them have something right. But I think we should read extensively first. We should read books in many fields, and read selectively in one field.
