状语从句知识点详解（初中英语专项复习）状语从句的概念: 用一个句子作状语来修饰动词和形容词，以表明动作发生或状态存在的时间、地点、原因等，这个句子就叫做状语从句。

状语从句的分类：状语从句共分为九大类，包括：时间、地点、原因、条件、让步、目的、结果、方式、比较状语从句。

下面分别讲解：一、时间状语从句概念：用来表示时间的状语从句，由when, while, as, till, until，before, after, since等引导。

由于时间状语从句的引导词所表示的意思并非一致，不同引导词表达不同的时间，它们在句子中对应的时态、语态等也有所不同。

例如：when /while引导的时间状语从句when引导的从句的谓语动词通常是瞬间动词，也可以是延续性动词。

从句动作可与主语动作通常先后发生也可同时发生。

I was writing when my sister came back.( come是瞬间动词，只能用when引导，不能用while)He often wrote me when/while he studied in Shanghai International Studies University.( study 是延续性动词，while可代替when)While my mother was cooking , I was playing chess with dad. (cook是延续性的动词，cook和play同时发生)I like playing chess while my sister likes reading stories.我喜欢下棋，而我姐姐喜欢看小说。

(while表示对比)when和while的区别还有：while引导的时间状语从句多用于进行时态，而when引导的时间状语从句多用于一般时态。

While we were playing games, our headmaster called me .我们正在做游戏的时候，校长叫我了。

从第一句话的句子结构和句子的意思分析，此句应是强调句型，被强调的内容为：for two months，所以用that引导。

第二句的结构为：It is+ 一段时间+since，意思为“……已经多久了”。

故选A。

2．_________I saw him, I knew he was the man the police were looking for.A．The place B．The week C．The day D．The instant全面解析：一看见他，我就知道他是那个警察正在寻找的人。

分析句子，I saw him 与I knew he was the man.，为两个完整的句子，此处需用连词连接。

the instant 译为“一……就”时，引导时间状语从句符合句意，故选D。

3．It was ten years they got married.A．When B．that C．Since D．before全面解析：十年后他们才结婚。

it is +时间+before...，固定句式，“.....以后才.....”,before引导时间状语从句，故选D。

4．He was about to go to bed ________ the doorbell rang.A．while B．as C．before D．when全面解析：他刚要上床就在这时门铃响了。

主语+was/were about to do... when...，固定句式，“正要做......，这时......”，此处when为并列连词，在意义上等于and at that time/and then ，故选D。
