TASK TWO 主要为Expository Writing (论说文)，根据不同题目，又可分为Discussion 和Argumentation两种类型。
国外有些参考书分为Report 和Essay两种。现就如何区分这两种类型说明如下：
一、 Discussion / Report 型
Discussion / Report 型主要目的是提供事实和信息或提出问题和阐述解决问题的方法。
二、 Argumentation / Essay 型
Argumentation / Essay 型主要目的是提出并论证一个观点或假设，或者陈述及评估反方观点，论据等。
举例说明：
Task: Many people believe that birth control will solve the problems of overpopulation and poverty in the world.
a. Do you agree? Give examples to support your argument. Other people, however, claim that it is inhuman
to exercise birth control and that it doesn’t work well in many places. Write an argument to support either
side of the issue.
b. Explain how your county uses birth control to solve the problem of overpopulation and alleviate poverty.
经过分析，大家可以看出，a 属于Argumentation ， 而b属于Discussion.
