III 比較對比型

        1) 概念判斷

       判斷一道作文題是否屬于“比較對比型”，可以看題目中是否包含下列詞匯：compare and contrast，compare，advantages and disadvantages等。例如：

       1. （4題）

       It has been said, "Not everything that is learned is contained in books." Compare and contrast knowledge gained from experience with knowledge gained from books. In your opinion, which source is more important? Why?

       2. （5題）

       A company has announced that it wishes to build a large factory near your community. Discuss the advantages and disadvantages of this new influence on your community. Do you support or oppose the factory? Explain your position.

       3. （113題）

       The government has announced that it plans to build a new university. Some people think that your community would be a good place to locate the university. Compare the advantages and disadvantages of establishing a new university in your community. Use specific details in your discussion.

       由上述三道題中的compare and contrast，advantages and disadvantages可以判斷它們都屬于“比較對比型”的題目。由此可見，比較對比型和之前介紹過的二選一型有個區別，它要求考生必須兩個觀點或方面（即優缺點）都要提到，它顯然是不能用單邊論證結構。它可以采用的結構如下。

       2) 對應結構分析

       雙邊論證

       雙邊論證基本為四段論，它與單邊的最大區別在正文，正文兩段分別對題干提出的兩個觀點或優缺點進行論證。現通過上面的例題二來理解這一結構的使用：

       原創范例（5題）

       Introduction: The new factory does bring a range of benefits, yet the residents are not advised to establish it.

       Main body 1:

       Topic sentence: Admittedly, the residents and the local government as well gain benefits from the construction of this factory in the community.

       Reason 1: For one thing, a new factory requires plenty of new workers, providing employment opportunities for the community.

       Reason 2: For another, the new factory is certain to pay tax to the indigenous government, and thus enhance the tax income of the whole community.

       Main body 2:

       Topic sentence: However, building a large factory could bring along a great many disadvantages.

       Reason 1: First and foremost, a large factory will definitely produce pollution to the community.

       Reason 2: In the second place, it is possible that traffic jams could happen due to the returning tide during rush hours.

       Reason 3: Last but not least, flowing population resulted from the establishment of the factory will undoubtedly increase, which casts threat to the community.
