时间状语从句讲解和练习
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.

As we age, we trade strength for ingenuity, speed for thoroughness, and passion for reason. 随着年龄的增长，我们用力量换来了机敏，以速度换来了严谨，以热情换来了理智。 注：1)when还可作并列连词，其意义为“那时，这时”，相当于and at this/that time。常用于下列句式： sb.was doing sth.when...某人正在干某事就在这时…… sb.was about to/ going to do sth.when...某人正打算干某事就在这时…… sb.body has just done sth.when...某人刚干了某事就在这时…… 2)如果主句表示的是短暂动作，而从句用延续性动词的进行时态表示在一段时间内正在进行的动作时，when，while 与as可互换使用。如： When/While/As I was walking down the street，I came across an old friend of mine. 2、before/ after It will be five years before we meet again.五年之后我们才能见面。 After you think it over, please let me know what you decide. After her husband had gone to work, she sent her children to school. 3、until, till, not...until 1)肯定句：主句的谓语是延续性动词，主从句均为肯定式，意为“某动作一直持续到某时间点才停止”
(完整版)初中英语语法专题(状语从句)讲解
初中英语语法专题（状语从句）讲解 状语从句在复合句中作状语，修饰动词、形容词或副词等。状语从句可以表示时间、条件、原因、地点、目的、结果、让步、方式、比较等意义。 知识梳理：提纲挈领，抓住重点和难点！ 各类状语从句连接词（短语）一览表： 时间 when, while, as, as soon as, since, until, after, before 条件 If, unless 原因 As, because, since 地点 Where 目的 So that, in order that 结果So that, so…that, such…that 让步 though, although, even if, however 方式 As 比较 t han, (not)as…as, 时间状语从句： Whenever he comes, he brings a friend. 他每次来都带个朋友。 条件状语从句： As long as I am alive, I will go on studying. 只要我活着，我就要学习。 原因状语从句： Since we live near the sea, we enjoy nice weather.由于我们住在海边，能享受到好的天气。 地点状语从句： Put it where we can all see it.把它放在我们都能看到的位置。 目的状语从句：
Finish this so that you can start another.把这个做完，你可以开始另一个。 结果状语从句： He was so angry that he couldn't say a word. 他气得说不出话了。 让步状语从句： Though he is in poor health, he works hard.虽然他身体不好，但是他工作很努力。 方式状语从句： Students do as the teachers say.学生们按照老师说的去做。 比较状语从句： The work isn't as easy as I thought.这项工作比我想象得难。 例题解析：举一反三，学的更轻松！ 1. 易混引导词while, when, as的区别： when既可以指"时间点",与瞬间动词连用，也可以指"时间段"，与延续性动词连用 （=while）。如： When he came in, his mother was cooking. 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. As与when用法相似，但着重强调主句动作与从句动作同时发生，有"随着……"或"一边……一边……"之意。如： As you get older, you get more knowledge.随着年龄的增长，你获得的知识就越多。 2．Because,as,since 的区别： Because用于表示直接原因,回答why提出的问题，语气最强；As用于说明原因, 着重点在主句，常译成"由于"；since表示显然的或已知的理由或事实，常译成"既然"。如： Water is very important because we can't live without it. He didn't come yesterday as his mother was ill. I'll do it for you since you are busy.
状语从句用法讲解和练习
第章状语从句 学习指导 状语从句在句子中作状语，用来修饰主句或主句的谓语。一般可分为九大类,分别表示时间、地点、原因、目的、结果、条件、让步、比 较和方式。尽管种类较多,但由于状语从句与汉语结构和用法相似,所 以理解和掌握它并不难。状语从句的关键是要掌握引导不同状语从句的常用连接词。现分别列举如下: 状语从句分九类： 在这一章节的学习中，要求同学们掌握各类状语从句基本概念，并能够灵活应用。 第一节时间状语从句 时间状语从句用一般现在时表示将来。连接时间状语从句的连接词有：2．when，while，as均可表示“当……的时候”。 when强调“特定时间”，表示主句谓语动词的动作与从句谓语动词的动作是同时发生的，或从句的动作发生在主句的动作之前；while表 示的时间是一段，而不是一点，as多用在口语中，强调“同一时间”或“一前一后”，有时还有“随着”的含义。 When spring came, he felt like a trip.春天来了，他想去旅游。 As spring warms the good earth，all flowers begin to bloom．(as有“随着”的含义) as, when, while都表示主、从句的动作或状态同时发生，但三者也有
区别。as和when引导的从句既可表示一点时间，也可表示一段时间，从句中的谓语动词既可以是持续性动词，也可以为短暂性动词，经常可以互换使用；while引导的从句通常表示一段时间，从句中宜用持续性动词作谓语。当从句中的谓语动词为持续性动词时，这三者可以通用（前面例句中已有体现），再如： 1 / 18 Mother was worried because little Alice was ill, especially as / when / while father was away in France.妈妈担心，因为小艾丽思病了，特别是当父亲远在法国的时候。 如果从句和主句要表示一个人的两个动作交替进行或同时完成时，则多用as，可译为“一边......，一边......”。例如： He looked behind from to time as he went.他一边走，一边不时地往后看。 As time goes on, it's getting warmer and warmer..随着时间的推移，天气变得越来越暖了。 I thought of it just as you opened your mouth.你一张嘴我就知道你要 说什么。（若表示两个短促动作几乎同时发生时，用as的场合多于when.） 当主从句之间表示转折或对比关系时，多用while, 不用as或when。如：

时间状语从句讲解讲课教案
（adverbial clause of time） 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, as，after,before,since,untill,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：主过从过；主将从现；主句为一般现在时，从句不受影响。 编辑本段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。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 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） 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 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
