很多同学在作文中倾向于用人开头来写句子，譬如名词people, 代词we, I, He, She, They等。尤其是在SAT写作中，例子占了很大的比重，有的同学的作文整个段落所有句子都是以he或she开头，这样的句子多了，难免会让人厌倦。那么如何给这些句子作些改变，让作文更灵动一些，这里给大家提供几个参考：

1. 用普通名词作主语

对比以下三组句子：

A: I have an idea.

B: An idea was thought up by me.

C: An idea came into my mind. /An idea occurred to me.（推荐）

不难发现三句都没有错误，第一句是最常见的句子，口语中完全可以说；第二句是以普通名词做主语的被动句，但SAT写作中并不推荐，大家在SAT官方指南中对于语言这一部分可以看到详细的说明“use ACTion words”以及“you should change the passive voice into ACTive voice.”当然，如果动作的发出者不重要或其他特殊情况另作他论，这里不过多解释。第三句则是以普通名词做主语的拟人句，是我所推荐的句子，既改变了句子的开头，又不困于被动。

再看几个例子对比：

A: As long as you compare the two examples, you will find the differences.

B: The differences will be revealed if you compare the two examples.

C: A comparison between the two examples will reveal their differences.（推荐）

A: He was poor and he was ill.

B: He led a poor life and suffered from illness.

C: Abject poverty and severe illness overwhelmingly destroyed his life. （推荐）

2. 用时间作主语

传统上，大家更习惯于用时间作状语，但用时间作主语，用witness, be accompanied by等作谓语也是一个很好的选择。

A: In his last ten years, he suffered from severe illness and abject poverty.

B: His last ten years was accompanied by severe illness and abject poverty. （推荐）

3. 用to do/ing形式作主语

这样的句子很简单，关键是要有改写的意识。

A: We should make contribution to the prosperity of society.

B: Making contribution to the prosperity of society is everyone’s obligation.
