时间状语从句英语 从句用主将从现。用表示时间的连词连接一个句子作状语，这样的主从复合句就是时 间状语从句。连接时间状语从句的连接词有：when, before, after, while, as soon as, until, since...... 这里要注意一点的是，如果主句是一般将来时，从句只能用一般现 在时表示将来意义。 引导的时间状语从句的主从复合句中，动作发生在先的用过去完成时，在后的`用过 去时。表示前面的叙述所没有提到过的信息。它总是对所描述的事件予以引人注目的强调，意为“这时；突然”；当位于句末的分句具有引种用法时，大致有以下三种情况： a. when 分句前面的分句采用过去展开时。例如： he was still smiling when the door opened and his wife came in. 他正笑着的 时候，门突然开了，他妻子走了进来。 b. when 分句前面的分句采用 was （were） about to， was （were） on the point 等。例如： we were about to start when it began to rain. 我们刚要出发就开始下雨了。 c. when 分句之前的分句用过去顺利完成时，其中 sb had hardly / scarcely /barely … when 已沦为紧固词组。例如： (1) we had hardly fallen asleep when the bell rang. 我们刚刚入睡，铃声就响 了起来。 (2) he had scarcely arrived when he had to leave again. 他刚刚抵达就又必须 离开了。
4种 句动作同时发生或从句动作先于主句。(既可引导时间点又可引导时间段) I was thin when I was a child. The film had been on when w e arrived. 2. be about to do … when … be doing …when… be on o ne’s way … when … be on the point of doing …when… had done … when… “ 在那时”“这时”,表示某件事正在发生或刚刚发生，另一动作同时发生 The telephone was ringing when I got home. I was about to go to bed when he came back. W e w ere just on the point of calling you up when you came in. 3. When 还以引导条件状语从句相当于if How can I explain it to you when / if you won’t listen. How can you get good records when you don’t study? When you read it again, the meaning will become clearer to you. 4.When还可引导原因状语从句，“既然” It was foolish of you to take a taxi when you could easily walk there in five minutes. 3种 1. 必须引导持续性动作，强调在一段时间内，主句和从句动作同时发生。 My mother was cooking while I was doing my homework. Please don’t talk so loud while others are working. 2. “然而” 表示轻微转折, 两者对比。 I like watching TV while he likes reading. 3.引导让步状语从句“ 虽然，尽管” While I admit his good points, I can see his shortcomings. 1 As I left the house , I forgot the key.我离开家时，忘记了带钥匙。 As 引导时间状语从句，强调动作并行发生，不指先后。 2. As I get older, I get more optimistic. 随着年龄的增长，我变得更加乐观“随着” 表示时间的推移。 3. He hurried home, looking behind as he w ent. 他匆匆忙忙回家，边走边往后看。“一边…一边…” 4 As he was going out, it began to rain. 当他出去时开始下雨了强调两个动作紧接着发生。 5. As a boy (When he was a boy), he was hopeless at English.
时间状语从句常由以下连接词引导：when（当……时），as（一边……一边；当…时），while（在……期间），after（在……之后），before（在……之前），as soon as（一……就），since（自从），till(until)（直到……，直到……才），whenever（任何时候），the moment（一……就），no sooner than（一……就），hardly…when… （一……就）等。由以上连接词（或词组）连接的主从复合句中，主句和从句的动作，有的是同时发生，有的是先后发生。因此，要特别注意根据连接词所代表的时间不同，主句和从句的谓语要使用相应的时态。这是掌握时间状语从句的关键。 1. when 和whenever 引导的从句：从句的动作和主句的动作可以同时发生，也可以先于主句的动作发生。例如： When we reached home, it was already dark. 我们到家的时候天已经黑了。 When my cousin came yesterday, I was playing volleyball. 昨天我表哥来时，我正在打排球。 When it rains, I go to school by bus.下雨的时候，我坐车去学校。 I shall tell her the good news when she comes. 她来时，我将告诉她这个好消息。（主从句都表示将来发生的动作，但要注意从句中要用一般现在时，表示将来。） Come to see us whenever you can.你什么时候有空，就过来看看我们。 2. while 和as 引导的从句：while表示“当…过程中”，强调某一段时间主句和从句的动作在同时发生。as表示“当…时”或 “一边…一边”，主句和从句的动作同时发生。例如： Work while you work; play while you play. 该工作的时候就工作，该玩的时候就玩。 While he is reading, he always makes notes. 他经常一面看书，一面做笔记。 She sings as she goes along.她边走边唱。 You will grow wiser as you grow older. 随着年龄的增长，你会更加聪明起来。 3. before 和after 引导的从句：前者一般表示主句的动作发生在从句动作之前。后者表示主句的动作发生在从句动作之后。 例如： I didn’t know any English before I came here. 我来这儿之前，一点英语都不懂。 I had written my report before my mother came back.
英语中时间状语从句 1、时间状语从句可由when，whenever，while，before，after，until，till，since，now that，once，as soon as等连词引起：Let’s wait until(till)the rain stops． 等雨停了再说。 She comes to talk to me whenever she feels lonely． 每当她感到寂寞时就来和我聊天。 As I talked，I gained some confidence． 我一面谈着一面增强了信心。 Now that I have come back,I want to help you both． 现在既然我回来了，我要帮助你们两人。 Once the train is moving，there is no way to stop it． 一旦火车开动了就没法址它停下来。 2、由every time，the moment等词引起的从句也可以用作状语

时间状语从句讲练 一.概述 概念：在复合句中，由时间连接词引导的表示时间的状语从句叫做时间状语从句。（在复合句中，要注意主句和从句的时态大多都要保持一致。） 一般来说，时间状语从句常由连词when, before, after, as soon as或until等引导。在使用时，从句一般不用一般将来时态。若主句为一般将来时态或是含有将来的意味时，时间状语从句常用一般现在时态来代替将来，即“主将从现”。如： I will go to the cinema as soon as I finish my homework. 我一完成作业就去电影院。 When I grow up, I will join the army. 当我毕业了，我就要去参军。 二.常用连接词举例 1.when连接的时间状语从句 when相当于汉语的“当……时候”。如： When the weather is fine, many families go out for a walk. 天气好时，很多家庭都出去散步。 When I got home, I found mother cooking for me. 我到家时，发现妈妈在为我做饭。 I always go to see the doctor when I do not feel well. 我感到不舒服时总要去看医生。 Please let me know when you have trouble. 有因难时请告诉我。 2.before/after连接的时间状语从句 before表示“在……之前”，after表示“在……这后”。如： He telephoned that he couldn’t come before the concert began. 他打电话来说音乐会开始前来不了了。 Mother always prepares supper before I come back from school. 妈妈总是在我放学回家前把晚饭准备好。 I will go out to play basketball with you after I finish my homework. 我做完功课后就和你一起出去打篮球。 3.as soon as连接的时间状语从句 as soon as表示“一……就……”，强调动作紧密相连。如： We start to sing as soon as it is 12o’ clock. 一到 12 点，大家就开始唱起来。 We began t work as soon as we got there. 我们一到那儿，就马上开始工作。 4.until连接的时间状语从句 until表示一个动作一直持续到某一时刻，即“直到……”。如： He waited until all the people left. 他一直等到所有的人都走了。 I didn't go to bed until Mum came back. 直到妈妈回家后我才上床睡觉。 5.while连接的时间状语从句 while 连接时间状语时，表示主句的行为在从句行为过程之中发生。由于while 从句表示一个持续的行为，所以从句中要用持续性动词或状态动词，并且持续性动词常用进行时态。如： while they are waiting for the New Year, they listen to music, sing songs and have fun.
时间状语从句 用句子表达一件事情或一个行为发生的时间，这个句子就叫时间状语从句。时间状语从句根据其所表示的时间不同，所使用的连词也不同。下面我们一起来看一下几个常见的时间状语从句： 1．when引导的从句：表示主句的动作和从句的动作同时发生，或从句的动作发生在主句动作之前。 例如：I was going out when a visitor came. (动词动作同时发生。)我正要出门，有客人来访。 I shall tell her the good news when she comes.她来时，我将告诉她这个好消息。 小试牛刀：I found mother cooking for me. I got home.(when)_______________________________________ He was listening to the radio when I home. (get) 2．while 引导的从句：表示“当……过程中”，强调某一段时间内主句和从句中谓语动词所表示的动作在同一时期发生。由于while从句表示一个持续的行为，所以从句中要用持续性动词，并且持续性动词常用进行时态。例如：Keep an eye on my little sister while I am away.我不在时，请照看一下我的小妹妹。 While we were watching TV, Jim came in. 我们看电视的时候，Jim进来了。 小试牛刀：It started to rain. We were playing football.(while)_______________________________________ Lucy was cleaning the room Lily was listening to music. 3．as引导的时间状语从句：表示“当……的时候；一边……一边……；随着……”，其从句的主语与主句的主语往往是同一人或物。 例如：She sang as she worked. 她一边工作一边唱歌。=She was singing as she was working. I saw him as he was getting off the bus. 正当他下公共汽车时, 我看见了他。 小试牛刀：we walked, we talked. You will grow wiser you grow older. 4．before引导的从句：一般表示主句的动作发生在从句动作之前。 例如：I didn’t know any English before I came here. 我到这儿来之前，一点英语都不懂。 例如：I had written my report before my father came back. 小试牛刀：He bought the ticket he went to see the film. 5．after引导的从句：表示主句的动作发生在从句动作之后。 例如：After he locked the door, he left. 他锁上门后，就走了。 After he had finished his work, he played a game of chess with his friend. 他做完工作后，和朋友下了一盘棋。小试牛刀：I will go out to play basketball with you. I finish my homework.(after) _______________________ _ He left the classroom he had finished his homework the other day. 6．since引导的从句：表示“自从……以来”，从句中的动词一般表示动作的起点，用过去时。主句中的动词表示动作延续的情况，一般用现在完成时。如果主句中的动词表示的不是延续的动作而是表示目前的状态，可用一般现在时。 例如：Since he met this good friend, he has made great progress in his studies. 自从遇见了这个好朋友，他已在学习上取得了巨大的进步。 例如：It is twenty years since she joined the Party. 她入党二十年了。（主句中的动词表示的是状态，用现在时。）小试牛刀：it is five years since we last time.（meet） Mr green has taught in that school since he (come) to China three years ago. 7．until 引导的从句：表示一个动作持续到某一时刻。 （1）表示“直到……”，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。（2）表示“直到……才”，主句用否定式，从句用肯定。如果主句中的谓语动词是瞬间动词时，必须用否定形式。例如：They worked until it was late. 他们一直工作到天黑。
概念：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。(在复合句中，要注意主句和从句的时态大多都要保持一致。） 1.由when, while, ,just ,just as, as，after, before, since, until, as soon as,引导的时间状语从句。 例如： When you think you know nothing, then you begin to know something. 当你以为自己一无所知的时候，你就是在开始知道一些事物了。 When truth is buried under the ground ，it grows, it chokes, it gathers such an explosive force that on the day it bursts out , it blows up everything with it. 当真理被埋在地下的时候，它在生长，它感到压抑，它蓄存着这么一种爆炸性力 量，一旦冒出，它就会炸破一切！ Strike while the iron is hot. 趁热打铁。 You can feel the air moving as your hand pushes through it. 当你的手在空气中挥动的时候，你就能感觉到空气在流动。 Our headmaster laughed as she spoke. 我们的校长边谈边笑。 主要时态：主现从不现；主过从四过；主将从现。 when, while和as的区别 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；动作既可以和主句的动作同时发生，又可以在主句的动作前后发生。并且when有时表 示“就在那时”。 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。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） 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： ）”一边……一边“表示as我们总是边走边唱。（We always sing as we walk. As we were 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） 2.由before和after引导的时间状语从句。注意before引导的从句不再用否定式的谓语，并且当before引导的从句位于主句之后，有时译成“就，才”。还要注意主句和从句之间的时间关系。当主句用将来时，从句总是用现在时；如果before
when, while和as的区别 when引导的从句的谓语动词可以是延续性的动词，可以是瞬时动词。并且when有时表示“就在那时”。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。 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） 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 were 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） 由before和after引导的时间状语从句 注意before引导的从句不再用否定式的谓语，并且当before引导的从句位于主句之后，有时译成“就，才”。还要注意主句和从句之间的时间关系。当主句用将来时，从句总是用现在时；如果before引导的主句谓语用的是过去完成时，则从句动词多用一般过去时，这样以便体现动作发生的先后。After表示主句动作发生在从句动作之后。主句和从句的动作的时间关系正好与before引导的从句相反。例如： It will be four days before they come back. 他们要过四天才能回来。 Einstein almost knocked me down before he saw me.爱因斯坦几乎把我撞倒才看到我。 My father had left for Canada just before the letter arrived.我父亲恰好在信到之前去加拿大了。They had not been married four months before they were divorced. 他们结婚还不到四个月就离婚了。 After you think it over, please let me know what you decide.你仔细考虑过以后，告诉我你是怎样决定的。 After we had finished the work, we went home.完成工作之后，我们回家了。（从句用过去完成时，主句用一般过去时） 由till或until引导的时间状语从句。 till和until一般情况下两者可以互换，但是在强调句型中多用until。并且要注意的是：如果主句中的谓语动词是瞬时动词时，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。till不可以用在句首，而until可以放在句首。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。 It was not until the meeting was over that he began to teach me English.直到散会之后他才开始教我英语。 I worked until he came back.我工作到他回来为止。
