1什么是状语从句

状语从句 (Adverbial Clause) 状语从句指句子用作状语时,起副词作用的句子。它可以修饰谓语、非谓语动词、定语、状语或整个句子。根据其作用可分为时间、地点、原因、条件、目的、结果、让步、方式和比较等从句。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。

2状语从句考点分析:

1. 状语从句虽然有完整的主谓结构,却是不能独立的从句。

2. 状语从句它由从属连词引导成为整个句子一个不可缺少的部分。

3. 考查的热点有条件、时间、地点、让步等状语从句的连接词词义辨析.

4. 动词的时态呼应、状语从句的省略等。

5. 题干结构呈交叉和综合特征,选项设计多从定语从句和名词性从句的角度进行思维干扰。

3状语从句时态特点

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:

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. 我一完成此工作,就回家。

(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)

If he comes back, please let me know.如果他回来了,请通知我。

(从句中的谓语动词用comes back,表示一般将来时,绝不可用will come back)
