什么是状语从句呢

生活经验佚名2023-04-28

状语从句是指句子用作状语时,起副词作用的句子。状语从句中的从句可以修饰谓语、非谓语动词、定语、状语或整个句子。状语从句一般由连词(从属连词)引导,也可以由词组引起。从句位于句首或句中时通常用逗号与主句隔开,位于句尾时可以不用逗号隔开。

状语从句的时态特点

一般情况下,时间和条件状语从句的谓语动词一般用“一般现在时”表示“一般将来时”,用“现在完成时”表示“将来完成时”。例如如下:

I will call you as soon as I arrive in Beijing. 我到北京就将给你打电话。

(这是由as soon as引导的时间状语从句,从句中的谓语动词arrive是一般现在时,表示一般将来时,绝不可用will arrive)

As soon as I have finished this work, I will have gone home.如果我早完成工作的话,我现在已经到家了.。

(从句中的谓语动词用现在完成时have finished,表示将来完成时,绝不可用will have finished)

状语修饰动词、形容词、副词或整个句子。通常由副词、介词短语、动词不定式、分词和从句等担当。例如:

1. Naturally, our grandparents were pleased to get our phone call.(副词)

当然,我们的祖父母乐于接到我们的电话。

2. We worked hard, from sunrise to sunset.(介词状短语)

我们工作得很努力,从日出到日落。

地点状语从句

特殊引导词:wherever, anywhere, everywhere

Generally, air will be heavily polluted where there are factories.

一般来说,有工厂的地方空气污染就严重。

Wherever you go, you should work hard.

无论你去哪里,你都应该努力工作。

地点状语从句一般由连接副词where, wherever等引导,已经形成了固定的句型,例如:

They were good persons. Where they went, there they were warmly welcomed.

他们都是好人。因此他们走到哪里都受到热烈欢迎。

目的状语从句

常用引导词:so that, in order that

特殊引导词:lest, in case, for fear that,in the hope that, for the purpose of , to the end that

The boss asked the secretary to hurry up with the letters so that he could sign them.
