为了使讲话和行文简洁，句中某些成分有时可省略。
省略可分以下几种情况：
一）简单句中的省略。
1、省略主语：祈使句中主语通常省略。
其它省略主语多限于少数现成的说法。

2、省略主谓语或主谓语的一部分。 (there is) no smoking.(is there) anything wrong?

3、省略作宾语的不定式短语，只保留to。 -are you going there?--i’d liketo(go there).

形容词：glad, happy, pleased, delighted, …
短语：be going to, be about to, be able to, h**e to, used to, ought to, …
注意：如果该宾语是be动词或完成时态，则须在to之后加上be或h**e。 -are you an engineer?--no, but i want to be.
---he hasn’t finished the task yet.--well, he ought to h**e.
4、省略表语。
---are you thirsty?--yes, i am (thirsty).

2、省略了一个从句或从句的一部分，用so或not（切不可用it或that）代替。 -is he coming back tonight?--i thinkso.

这种用法常见的有：how so? why so?
