同雅思一样，托福写作的要求也有句型结构多样性这一项，那么如何显得自己的句子结构多变，长短句结合呢？环球教育老师具体为考生先来介绍一下如何写好并列句，从基础开始逐渐深化句型的多样性。
   最常见的并列句就是用and，but等作为连接词，将两个分句连接起来。比如：
   历史必然含混也因此必然有趣。
   History has to be vague and is therefore very interesting.
   在中国孩子们没有权利也因此做一些自己不喜欢做的事情。
   In China children have little rights and therefore have to do many things that they do not enjoy doing.
   计算机不仅给人们带来了方便，还使人们学得更多。
   Computers have not only brought convenience but they have also made people learn more.
   从这些例句，我们可以得到以下这些结论：
   1、尽量使用复数名词作主语
   之所以提出这样的建议，是因为复数名词更能说明某个群体的共性，具有说服力，个体例子可能比较典型，不足以论证你的观点。
   2、能用过去式就用过去式，能用完成式就用完成式
   3、用not only把第一个谓语动词切开，用but also把第二个谓语动词切开
   常见的三种句子切分结构：
   主语和谓语切开（要求主语超过一个词）
   Those parents, however, have supported such a stupid decision.
   助动词和实义动词切开
   Those parents have , however, supported such a stupid decision.
   系动词和表语切开
   It is, however, hardly true that……
   4、不是省略而是替换（代词）
   例：6. If you could change one important thing about your hometown, what would you change? Use reasons and specific examples to support your answer.
