状语从句的简化
?状语从句的省略
状语从句同时具备下列两个条件:
①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。例如：
When ( the lab is ) completed ,the lab will be open to the public .
He’ll go to the seaside for his holiday if (it is ) possible.
另外，比较状语从句经常省略。例如：
I’m taller than he (is tall ).
The higher the temperature (is), the greater the pressure (is ).
状语从句的简化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;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。
(1)当状语从句的主语是it,且谓语动词是be时,it和be要完全简化掉。例如:
If (it is) possible, he will help you out of the difficulty.
You must attend the meeting unless (it is) inconvenient to you.
(2)当状语从句的主 语和主句的主语一致时,从句可以将主语和be动词简化掉。
