例如: He was working when I went in. 我进去时他正在工作。 When she heard the news, she began to cry. 她听到这个消息,她哭了起来。 (3) while引导的状语从句中常用延续性动词或表示状态的动词,意思是“在……期间”。 while还可以表示两者之间的对比关系。 They rushed in while we were singing. 我们唱歌时,他们冲进来。 I like playing football, while Tom likes listening to music. 我喜欢踢足球,而汤姆喜欢听音乐。 (4) as引导状语从句,强调同时发生,不分先后。可以译成“随着”或“一边……一边”。 例如:John sings as he walks home. 约翰一边往家走一边唱歌。 (5) since引导状语从句,主句常用现在完成时,从句常用一般过去时。 We have been friends since we met in Beijing. 自从我们在北京遇到就一直是朋友。 It has been six years since she left school. 自从她毕业已经有六年了。 (6) until/ till 引导时间状语从句,当主句的谓语动词是瞬间动词时,主句常用否定形式,not… until意思为“直到……才”。 He didn’t go to bed until he finished his homework. 他直到做完作业才睡觉。 2.地点状语从句:

When (While) we were at school, we went to the library every day. (2)While表示时间段,因此,while 从句的谓语动词要用延续性动词。如: Please don’t talk so loud while others are working.

初中英语状语从句

初中英语状语从句 一、时间状语从句 时间状语从句表示时间,引导词有: when, while, as, till, until before, after, since等。 时间状语从句的引导词所表示的意思不尽相同,要注意把握不同引导词所表示的不同时间关系,以及它在具体句子中对应的时态、语态等问题。 注意:as(在……时候,因为),since(自从,因为),它们可以引导时间从句,并强调主句和从句的动作同事发生。并且while有时还可以表示对比。例如: (1)While my mother was reading the newspaper, I was watching TV.(read是延续性的动词,read和watch同事发生) I like playing football while you like playing basketball. 我喜欢踢足球,而你喜欢打篮球。(对比) (2)when(当……的时候),引导的从句的谓语动词可以是延续性动词,也可以是瞬间动词。从句动作可与主语动作同事发生,也可在其后发生。 I was reading a book when she came into my room. (come是瞬间动词,只能用when引导,不能用while) I often missed my home when(while) I lived in NewYork. (live是延续性动词,when可用while代替)

(3)when和while的区别还在于: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 they were talking, the bell rang.正在他们谈话的时候,上课铃响了。 (4)as译作“一边……一边”、“随着……”,侧重主句和从句的动作同时发生。有时可与when,while通用。 We always sing as we walk. 我们总是边走边唱。(as表示“一边……一边”) As you grow, you will know more and more。 随着年龄的增长,你会懂得越来越多。 2.till或until引导的时间状语从句 till,until(直到……才):一般情况下两者可以互换,但是在强调句型中多用until。till不可以在句首,而until可以放在句首。注意:如果主句中的的谓语动词是瞬间动词时,必须用否定形式;如果主句中的谓语动词是延续性动词时,用肯定或否定形式都可以,但表达的意思不同。 例如: I didn’t go to bed until(till) my father came back. 直到我父亲回来我才上床睡觉。(go to bed 是瞬间动词,主句用否定形式) I talked until he came back. 我工作到他回来为止

初中英语语法——状语从句

状语从句 一、考点解读 今天我们复习状语从句,英语中状语与中文的状语大致相同,分为时间状语、地点状语、原因状语、目的状语、结果状语、条件 状语、方式状语等等。如果一个主从复合句中的从句是用来表示时 间,原因等等时,那就称为状语从句。 在主从复合句中修饰主句中的动词、形容词、副词等的从句叫做状语从句,又由于其功能与副词非常相近,又称做副词性从句。 状语从句一般可分为时间状语从句、地点状语从句、原因状语从句、目的状语从句、结果状语从句、条件状语从句、让步状语从句、比 较状语从句和方式状语从句九种。 这节课我们主要复习如下的内容: 1.时间状语从句 2.地点状语从句 3.原因状语从句 4.目的状语从句 5.结果状语从句 6.条件状语从句 7.让步状语从句 8.比较状语从句 9.方式状语从句 二、专题梳理 (一)时间状语从句 在句子中起时间状语作用的句子称为时间状语从句。时间状语从句可以放在句首、句中和句尾。 常用来引导时间状语从句的引导词有: when 当……时候

while 当……时候 as 当……时候、一边 after 在……之后 before 在……之前 since 自从 ever since 自从 once 一……就…… whenever 不管什么时候 by the time 到…… as long as 长达…… as soon as 一……就…… till/until 直到…… 1.when,while,as的用法 从属连词when,while,as都可用来引导时间状语从句,意为“在……时候”。但在具体用法上又不尽相同。 (1)这三个连词中,when用得最广,常可代替while与as。与while相比,when引导的从句动词既可是延续性的,也可是终止性的。as在这一点上与when相同,while所引导的从句中,动词只能是延续性的。在初中阶段,我们几乎很少讲as引导时间状语从句。是因为as在初中阶段是一种供了解性的内容。 e.g.When the fire broke out, all the students were sleeping soundly.(终止性的) 当火灾发生时,所有的学生正在熟睡 中。 The telephone rang while I was taking a bath.(延续性的) 我在洗澡时电话响了。

初中英语状语从句讲解

语法专题三状语从句 状语从句在复合句中起状语的作用,用来修饰主句中的动词,副词和形容词。状语从句由从属连词引导,从属连词在句中不充当句子成分,只起连接作用。状语从句多位于句首或句尾。位于句首时,一般要用逗号与主句隔开;位于句尾时,一般不用逗号。根据其含义状语从句可分为时间,地点,条件,原因,结果,比较,目的,方式,让步。 1. 时间状语从句 (1)时间状语从句常用when, as, while, before, after, since, till, until, as soon as/immediately/the moment(that)等连词来引导。例如: While he was doing his homework, the telephone rang. He had learned a little Chinese before he came to China. After he finished middle school, he went to work in a factory. (2)when,while,as都表示“当..的时候”,但是when引导的从句的动作和主句中的动词所表示的动作可以同时发生,也可以先后发生;while和as引导的则强调主句和从句的动作同时发生。While引导的从句谓语动词是延续性动词,且多用进行时,as则强调“一面…一面…”。注:while有时也还可以表示对比。 He was watching TV last night while l was writing a letter. As the children walked along the street,they sang happily. 练习: I was playing computer games I heard someone knocking at the door. A.as B.while C.when D.since (3)在时间状语从句里,通常不用将来时态,用一般现在时态表示将来的动作或状态。例如: I’ll ring y ou up as soon as I get to New York. (4)在带有till或until引导的时间状语从句的主从复合句里,如果主句用肯定式,其含义是“一直到……时”, 谓语动词只能用延续性动词。如果主句用否定式,其含义是“直到……才……”, “在……以前不……”, 谓语动词可用瞬间动词。例如: Let’s wait until the rain stops. We won’t start until Bob comes. 【Till是指直到某一特定事件发生的时候,而在那个时刻之后,该事情或状况仍将持续。Until是指直到某一特定事件发生的时候,而讲话的人在自己心里认为,在那个时刻之后,该事情或该状况将中止(不怎么可能持续)。固定组合里from morning till night,till/until是不能替换的,】 练习: -Hurry up.The bus is coming. -Oh,no.We mustn’t cross the street the traffic lights are green. A.after B.since C.while D.until (5)since引导的状语从句,从句中的谓语动词常为非延续性动词的一般过去式,主句的谓语动词表示延续,主句时态通常用一般现在时或现在完成时。 He has lived in the city since I came here. 补充:since从句中的谓语若是延续性动词或状态动词,则用一般过去时表示动作的完成或状态的结果。 We haven’t seen each other since he lived next door to me.
