状语从句的省略
状语从句同时具备下列两个条件:
主句和从句的主语一致，或从句主语为it；
②从句主要动词是be的某种形式。从句中的主语和be动词常可省略。

另外，比较状语从句经常省略。
I'm taller than he (is tall ).
The higher the temperature (is), the greater the pressure (is ).
状语从句的省略现象常存在于以下五种状语从句中:
①由if, unless等引导的条件状语从句;

10 12



②由although, though, even if though等引导的让步状语从句;
③由when, while, as, before, after, until till等引导的时间状语从句;
④由as, as if等引导的方式状语从句;
⑤由as, than等引导的比较状语从句。

下面针对这五种情形作归纳。

If (it is) possible, he will help you out of the difficulty.
