导语:英语语法:状语从句的省略用法讲解大全,看这个就够啦
我们常常将状语从句“简化”,让语言更加精炼简洁,状语从句“简化”在日常口语中也很常见。小编今天就给大家整理了状语从句的省略用法,看了这篇干货你会更加了解这些语法知识哦~
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 museum is) completed , the museum will be open to the public next year.
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。
下面针对这五种情形进行归纳~
(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.
如果可能的话,他会帮你摆脱困境。
You must attend the meeting unless (it is) inconvenient to you.
除非情况对你来说不方便,否则你必须出席这次会议。
(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。
常用于以下几种情形:
