　　作文練習：今天作文講正反觀點對比型議論文的寫作。

　　本類文章的一般結構為：

　　第一段：正方觀點。

　　第二段：反方觀點。

　　第三段：我的觀點。

　　評論性議論文只是客觀的分析和評論某一事物的正反兩個方面，或在某一問題上反映出來的兩種不同看法，并不下結論說其對或不對，正確或錯誤。這類作文主要適用于評論那些難以絕對說好或不好的主題，這時四級考試中經常出現的題目。

　　這類作文要求在比較所討論的兩個事物的優缺點時，要有自己的觀點傾向。對自己贊同的事物，其有點要多寫祥寫，而對其略點要少寫略寫。對反對的事物其有點要少寫略寫，一筆帶過，而對其缺點則要多寫祥寫。最后在我的觀點中對以上對比加以總結，明確表達自己的觀點看法。

　　Reading Selectively Or Extensively?

　　Outline:

　　1. 有人認為讀書要有選擇

　　2. 有人認為應當博覽群書

　　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.
