初中英语知识点总结：时间状语从句
时间状语从句在复合句中，由时间连接词引导的状语从句叫做时间状语从句。
时间状语从句通常由when, while, as，after,before,since,until等词引导。
一、时间状语从句种类1、引导的从句表示主从句的动作同时发生，或从句的动作在主句之前。
when引导的从句的谓语动词可以是延续性的动词，又可以是瞬时动词。
例如：When she came in, I stopped eating.她进来时，我停止吃饭。
(瞬时动词)When I lived in the countryside, I used to carry some water for him.当我住在农村时，我常常为他担水。
（延续性的动词）We were about to leave when he came in.我们就要离开，就在那时他进来了。
2、While引导的从句的谓语动作必须是延续性的，并强调主句和从句的动作同时发生（或者相对应）。
并且while有时还可以表示对比。
例如：While my wife was reading the newspaper, I was watching TV. (was reading是延续性的动词，was reading和was watching同时发生) I like playing football while you like playing basketball.我喜欢踢足球，而你喜欢打篮球。
（对比）3、As表示“一边……一边”，as引导的动作是延续性的动作，一般用于主句和从句动作同时发生；as也可以强调“一先一后。
例如：We always sing as we walk.我们总是边走边唱。
（as表示“一边……一边”）As we was going out, it began to snow.当我们出门时，开始下雪了。
（as强调句中两个动作紧接着先后发生，而不强调开始下雪的特定时间）4、由before和after引导的时间状语从句，表示两个动作一前一后发生。
时间状语从句的用法归纳总结
时间状语从句的用法归纳总结时间状语从句是一个从句，通常用来陈述一个动作或事件发生的时间。
下面是时间状语从句的用法的归纳总结：1. 时间状语从句通常以连词引导，常见的连词有：when, while, as, before, after, since, until, as soon as, once等。
例句: She arrived when the party started. (当派对开始时，她到达了。
)I will call you as soon as I finish work. (我下班后会立即给你打电话。
)2. 当主句和从句的动作同时发生时，使用连词when或while引导时间状语从句。
例句: I was studying when the phone rang. (电话响时我在学习。
)He was watching TV while his mother was cooking. (他妈妈在做饭的时候他在看电视。
)3. 当主句的动作在从句的动作之前发生时，使用连词before, after或once引导时间状语从句。
例句: She left before I arrived. (我到达之前她离开了。
)After he finished his homework, he went out to play. (他做完作业后出去玩。
)Once you finish your dinner, you can have dessert. (一旦你吃完晚饭，就可以吃甜点了。

)She will wait until you come back. (她会等到你回来。

时间状语从句知识点归纳
时间状语从句知识点归纳when/while/as 当……时，随着（一）when：表示“时间点”1. When my mother came into the house(=When coming into the house), she found me lying there awake .当我妈妈走进屋子时，发现我醒着躺在那。
这个句子主句是一般过去时，从句是一般过去时。
同时要注意，当从句主语和主句主语一致时，往往可以省略从句的主语，将从句谓语转化为现在分词形式即“when+Ving”这种短语形式代替状语从句；（二） while：表示“时间段”1、while they are arranging everything for their children, they are also interfering their growth.当他们在为子女安排一切的同时, 也在干涉他们的成长。
请大家注意以下几点：A. While译为“当...时”或“在…期间”，while引导的从句通常为进行时，即指一段时间，表示从句动作在进行时，主句动作也在进行中，所以此时主句一般也是进行时；B. While还能译为“趁”和“虽然/然而”，while译为“虽然/然而”时是让步状语从句。
如果发现while引导的状语从句与主句方向相反时，肯定是让步状语从句，表示“虽然/然而”，这一点要区分清楚。
（三）as：表示“随着”1、As Tony listened to those words, smile appeared on his face.随着托尼听到这些话, 微笑出现在了他的脸上。
这个句子主句是一般过去时，从句也是一般过去时。
A. As引导的从句侧重于表示主句发生的背景和条件，所以一般不为进行时，主句也不是进行时；B. As一般译为“随着”，当然也可以理解为“当…时”，不过从句的动作有持续发展之意，这一点不同于when/while。
时间状语从句
I waited till the rain stopped. 我一直等到雨停。 He didn’t give me the answer until I asked him the second time. 直到我问了第二次，他才回答我 的问题。
1.当某事正在进行的时候，又发生了另一件事， 这时三个词都可以引导时间状语从句。如： As/when/while I was walking down the street， I noticed a police car. 我在街上散步的时候,看到了一辆警车. 2.当两个延续性动作同时进行的时候，最常用 的是while。如： While my mother was cooking，I was doing my homework. 当我妈妈在做饭时，我正在做家庭作业。
As children get older, they become more and more interested in things around them.
随着孩子年龄的增大，他们就会对 他们周围的事情越来越感兴趣。

例如：1) The plane had taken off before he arrived at the airport.2) After he had lived in the south for 20 years, he decided to go to seek his fortune in the north.3) He was still tired even after he had had eight hours of sleeping.但是如果不强调先后，或是因为从句中使用的是某个状态动词，after和before句子结构中的谓语动词也可以都用一般过去时。
