复合句和简单句的转换(一)
1. 用“宾语+宾补”来代替“宾语从句”。

例句： I found him very happy. 我发现他很快乐。

I found (that) he was very happy. 我发现他很快乐。

2. 用“疑问词+动词不定式”来代替“宾语从句”。

例句： I don't know what I will do tomorrow.
我不知道我明天会干什么。

I don't know what to do tomorrow.
我不知道明天千什么。

注意：why 是不能和不定式连用的。

“疑问词+动词不定式”来代替“宾语从句”这种简化的前提是宾语从句的主语和主句的主语相同，且主句的谓语动词通常是know, remember, forget ,learn 等。

3. 用“动词不定式”来代替一些结果状语从句或者目的状语从句。

例句：He must get up early so that he can catch the first bus.
他必须早起以便他能赶上第一班公交。

He must get up early to catch the first bus.
他必须早起以赶上第一班公交。
