一、 长短句原则
As a creature, I eat; as a man, I read. Although one action is to meet the primary need of my body and the other is to satisfy the intellectual need of mind, they are in a way quite similar.
强烈建议：在文章第一段(开头)用一长一短，且先长后短;在文章主体部分，要先用一个短句解释主要意思，然后在阐述几个要点的时候采用先短后长的句群形式，定会让主体部分妙笔生辉!文章结尾一般用一长一短就可以了。
