第二章 段落的构成
段落是指一组相互关联，用来阐述某一中心思想的句子群。 一 段落和提纲 我们在写文章之前应该拟出一个提纲，而提纲的每一个

例如：要写一段中心思想是“I prefer to live in the city”的段落 请拟一个提纲：
1） Transportation and communication is more convenient than in the country. 2) Cultural life is richer.
提纲可以写成：
1） More land 2) Buildings Higher and Bigger 3) More People
二 段落主题句 （topic sentence)
主题句：每一段落只能包含一个中心思想，表达这一 中心思想 的句子就是主题句。
请找出下面段落的主题句。 There are two factors which determine an individual’s intelligence. The first is the sort of brain he is born with. Human brains differ considerably,some being more capable than others. But no matter how good a brain he has to begin with,an individual will have a low order of intelligence unless he has opportunities to learn. So the second factor is what happens to the individual------
the sort of environment in which he is brought up. If an individual is in poor environment, it is likely that his brain will fail to develop and he will never attain the level of intelligence of which he is capable. 主题句位于句首，后面的辅助句发展主题句的中心意念。
