时间状语从句用法总结： 1.引导时间状语从句的从属连词很多，如较基本的有before, after, when, while, as, since, till, until, as soon as 等。除以上基本的引导时间状语从句的从属连词外，还有些本来不是从属连词却可用作从属连词的词： 2.表示“一…就”的从属连词：the moment, the minute, the second, the instant, immediately, directly, instantly, once, no sooner…than, hardly…when等。 3.涉及time的几个从属连词：every time(每次)，each time(每次)，(the) next time(下次)，any time(随时)，the last time(上次)，the first time(第一次)。 4.当主句为将来时态或具有将来意义时，时间状语从句通常要用一般现在时表示将来意义，而不能直接使用将来时态。 5.与since 从句搭配的主句的时态通常是现在完成时态，在特定的语言环境中有时也可能用过去完成时或一般现在时。 状语从句的语法总结 1. 用when引导：when表示“当……时候”。如：Things were different when I was a child. 我小时候情况与现在不同。People breathe more slowly when they are asleep. 人睡觉时呼吸比较缓慢。2. 用while引导：while表示“当……时候”。如：We must strike while the iron is hot. 我们要趁热打铁。I went swimming while the others played tennis. 我去游泳，其余的人都打网球去了。注意：while 所引导的时间状语从句中谓语动词必须是持续性的，不能是短暂性的。3. 用as引导：as表示“当……时候”“随着”。如：He dropped the glass as he stood up. 他站起来时，把杯子摔了。We get wiser as we get old. 随着年岁的增长，我们也变得聪明些了。4. 用before引导：before表示“在……之前”。如：Turn off the lights before you go to bed. 睡觉前要关灯。Before he went to university he was a worker. 上大学之前他是工人。5. 用after引导：after表示“在……之后”。如：I will tell you after they leave. 他们走我再告诉你。After you finish the letter show it to me．信写完后给我看看。

一、when“当……时”,引导时间状语从句时,从句用于表示主句动作发生的特定时间.如： The days get longer when spring comes. = When spring comes, the days get longer. 春天到来时,白天变得更长了. 二、before“在……之前”,引导时间状语从句时,表示主句动作发生在从句动作之前.如： Close the door before you leave the room. 离开房间前关上门. 三、after“在……之后”,引导时间状语从句时,表示主句的动作发生在从句的动作之后.如： I went to school after I finished my breakfast. 吃完早饭后我就去上学了. 四、as soon as“一……就……”,引导时间状语从句时,表示主句动作紧接着从句动作发生.如： I’ll call you as soon as I get home. 我一到家就给你打电话. 五、until, till“直到”,引导时间状语从句.当主句谓语动词是延续性动词时,主句常用肯定形式；当主句谓语动词是非延续性动词时,主句要用否定形式,即“not…until/till…”意为“直到……才……”.如： I’ll wait here until/till the rain stops. 我将在这里等着,直到雨停. You can’t go home until/till you finish your work. 直到你完成你的工作,你才能回家. 下面再向大家透露点儿内幕消息,状语从句的两手绝活——时态的呼应和从句的位置.请看： 一、时态呼应 一般来讲,复合句都要遵循主、从句时态呼应规律,状语从句也不例外.即主句用现在时,从句也用现在时；主句用过去时,从句也用过去的某种时态.如： Be careful when you cross the road. 过马路时要小心. You must see the doctor if you are ill. 如果你生病了,你必须去看医生. 主句是一般过去时,从句也要用一般过去时.如： When he was seven years old, he could swim. 当他七岁时就会游泳. She turned off the light before she left the office. 她离开办公室前就关了灯. 二、主从句的位置. 大多数情况下,从句可以位于主句之前,也可以位于主句之后.不过从句在前时,主从句之间必须用逗号隔开.如： Please tell me when he comes back. = When he comes back, please tell me.

When (While) we were at school, we went to the library every day. 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.

状语从句是英语语法中的常用句型语法，那么大家是否清楚什么是状语从句呢?下面就是我给大家带来的初中英语状语从句详细解析，希望能帮助到大家! 状语从句详细解析 一、什么是状语、状语从句? 状语：是用来修饰动词、形容词、副词或全句用的。 eg：He works hard! (他努力工作)中的hard。 状语的位置： 修饰形容词或副词的状语放在被修饰语之前。 eg：The Summer Palace is very beautiful.颐和园非常美丽。 (very 为状语，修饰形容词 beautiful，放在 beautiful 之前)。 修饰动词的状语有的放在动词前，有的放在动词之后。 如果动词有宾语，状语一般须放在宾语之后。 eg： I He often came here to see me.他经常到这里来看我。(often 为状语，修饰动词came，放在前面)。 I know him well.我十分了解他。(well为状语，修饰动词 know，放在 know 之后)。 状语从句：用一个 句子 (从句)来作另一个句子(主句)的状语，用作状语的句子就叫作状语从句。作什么样的状语就叫什么类型的状语从句。例如：条件状语从句就是用一个句子来作条件状语。 二、状语从句的分类。 (1)时间状语从句 凡是从句都必须有引导词，引导时间状语从句的词有when，before，after，until，as soon as，while 等，具体用法如下： 1. when 意为“当……时”，引导时间状语从句，表示主句的动作和从句的动作同时或先后发生。 eg: I feel very happy when you come to see me. When you are crossing the street，you must be careful. when引导的时间状语从句，when的从句可以用延续性动词，也可以用瞬间动词。 eg：He was working at the table when I went in. 。 Someone knocked at the door when I was sleeping. I will visit my good friend when I have time. 注：when也可以作并列连词，表示一个动词正在进行的时候，突然间发生了另外一件事。 eg: I was fishing by the river，when someone called for help. We were working in the chemistry lab，when the lights went out. 2. before 意为“在……之前”，引导时间状语从句时，表示主句的动作发生在从句的动作之前。 eg: We cleaned the classroom before we left school yesterday. He had been a cook before he went to college . after 意为“在……之后”，引导时间状语从句时，表示主句的动作发生在从句的动作之后。 eg: After you use plastic bags，you mustn't throw them about. He called me after he had finished his work. 注：若主句和从句两个动作发生的先后顺序十分接近，那么也可以不用完成时态，如上面的 第二句可改成：He called me after he finished his work. 3. since引导的时间状语从句，译为“自从……”，主句常用现在完成时，从句常用一般过去时。 eg: I have taught English, since I came to Shenzhen. 注：常用句型：It is +时间段+since从句 译为：自从……有多长时间了。 eg. It is six years since she graduated from the university. 4. until 意为“直到……时”，引导时间状语从句时，表示主句的动作发生在从句的动作之前。 当主句的谓语动词是持续性动词时，主句常用肯定形式;当主句的谓语动词是非持续性动词时，从句常用否定形式，not…until… 意为“直到……才……”，这时的until可以用before 来替换。 eg：I'll stay here until you come back. 我会呆在这里，直到你回来。 (stay表示的 动作可以持续) He didn't go to bed until he finished his homework. 他直到做完作业才睡觉。(go to bed 表示的动作不能持续) 5. as soon as 意为“一……就……”，表示从句的动作一发生，主句的动作马上就发生。 eg：I'll tell him about it as soon as he comes back. 6. while引导的时间状语从句，常译为“与……同时，在……期间”，while的从句中常用延续性动词或表示状态的词。 eg. They rushed in while we were discussing problems. Father was cleaning the car while I was playing computer games. 注：while也可以作并列连词，表转折的关系，相当于but，译为“然而”。 eg. I like listening to music，while my brother likes doing sports. 7. till和until引导的时间状语从句，译为“直到……为止”，not … till / until引导的时间状语从句，译为“直到……才”。前者强调主句动作的结束，用延续性动词，后者强调主句动作的开始，用瞬间动词。 eg. I will wait for my friend until / till he comes. 我要一直等到我朋友来。 We won't start our discussion until / till he comes. 我们要等到他来了，再开始我们的讨论。 (2)条件状语从句 1.条件状语从句通常由if, unless引导。 eg：What shall we do if it snows tomorrow? Don’t leave the building unless I tell you to. 2.在条件状语从句里，谓语动词通常用现在时态表示将来的动作或状态。(主将从现) eg：I’ll help you with your English if I am free tomorrow. He won’t be late unless he is ill. 3.“祈使句 + and (or)+ 陈述句” 在意思上相当于一个带有条件状语从句的复合句。 eg：Hurry up, or you’ll be late.=If you don’t hurry up, you’ll be late. Study hard and you will pass the exam. =If you study hard, you will pass the exam. (3) 原因状语从句 1.原因状语从句通常由because, since, as引导。 eg：He didn’t come to school because he was ill. As it is raining, we shall not go the zoo. Since you can’t answer the question, I’ll ask someone else. 2. because表示直接原因，语气最强。Because引导的原因状语从句多放在主句之后。回答由why提出的问题，只能用because。As和since语气较弱，一般用来表示明显的原因。由as和since引导的原因状语从居多放在句首。 eg：------Why aren’t going there? ------Because I don’t want to. As he has no car, he can’t get there easily. 3. because和so不能同用在一个句子里。 For 语气最弱，它所引导的分句必须放主句后面，引补充说明作用。 eg：Put on more clothes, for it's cold outside. 注：because, since, as, for 的区别 语气位置意义 because最强前或后 “原因”;表客观因果关系;回答“” as 较强 前 “由于”;把众人所知的事实当作理由 since 较弱 前 “既然”;就对方陈述的事实作为理由 for 最弱 后 “理由”;对某一事实进行推断的理由 (4)地点状语从句 常用where(哪里)和wherever(无论哪里) eg. Where there is a will，there is a way. 有志者，事竟成。 We will go wherever the motherland need us most. 我们要到祖国最需要的地方去。
