初中英语时间状语从句讲解及练习
语法 29时间状语从句 一、什么是状语从句 状语就是在一句话中表示该句子的时间、地点、方式、原因、条件等成分。状语从句就是用一个从 句表示状语。状语从句根据它表达的意思不同，可分为时间、地点、原因、目的、结果、条件、方式、比较、让步等九类。 与状语一样，状语从句的位置比较灵活。既可置于主句之前（通常用逗号与主句隔开），也课置于主句之后（不需要用逗号与主句隔开），有时甚至可以置于主句之中。 二、时间状语从句 1. 主句和从句同时发生，这类从句由从属连词when, while, as引导。 He was hungry when he came home. I was crying while everyone was laughing. As I walked out, he walked in. as, when, while, 的区别 ① as强调从句的动作与主句动作同时发生及持续，具有at the same time的意思 他继续往下谈的时候，越来越兴奋。 as还可以表示一边??一边??，强调从句和主句中两个动作交替进行或同步进行。 他们边走边聊。 as还有“ 随着”的含义 随着春天的到来，天气暖和起来。 ② when 强调动作点的特定时间，具有at the time that 的意思 当老师走进来的时候，我们都站起来了。 ③ while 表示较长的期间，具有during the time that 的意思 当我在这的时候，我很安全。 2.主句发生在从句之前，这类从句由从属连词before, until 引导 ,before 意为“ 在---之前” until 在肯定句中意为“直到 --- 为止”，在否定句中意为“直到 --- 才”。从句既可置于主句前，也可置 于主句之后。 回家之前我必须干完所有的活。
时间地点原因状语从句
地点状语从句 常用连词：where 特殊连词：wherever (在……的任何地方), anywhere, everywhere 【点拨】地点状语从句与定语从句的区别：where引导定语从句时，从句前应有一个表示地点的名词作先行词；而状语从句前则无需先行词。 Go back where you came from.(where引导地点状语从句)你从哪儿来回哪儿去。Go back to the village where you came from. (where引导定语从句，修饰village)回到你来的那个村子里去。 时间状语从句 常用连词：when, as, while, as soon as, before, after, since , till, until, whenever (每当，一……就……) 特殊连词：the minute, the moment, the second, every time, the day, the instant, immediately, directly, no sooner ... than, hardly ... when, scarcely ... when 1．由when, while, as引导的时间状语从句when，while，as都有“当……时候”的意思。 1) when引导的从句的谓语动词既可以是延续性动词，又可以是瞬间性动词，并且when有时表示“就在那时”，相当于and at that time。 It was raining when we arrived. (指时间点)当我们到达的时候，天正在下雨。 When we were at school, we went to the library every day. (在一段时间内) 我们在学校上学的时候，每天都去图书馆。 We were about to leave when he came in.我们刚要离开，就在那时他进来了。 2) while引导的从句的谓语动词必须是延续性的，并强调主句和从句的动作同时发生(或者相对应)，此外，while有时还可以表示对比。 I like playing football while you like playing basketball. 我喜欢踢足球，而你喜欢打篮球。(对比) He fell asleep while/when reading.看书的时候，他睡着了。 Strike while the iron is hot. (用as或when不可以，这里的while意思是“趁……”) 趁热打铁。 3) as表示“一边……一边”，as引导的句子的动词是延续性的动词，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。 We always sing as we walk.我们总是边走边唱。(as表示“一边……一边”) Our headmaster laughed as she spoke.我们的校长边谈边笑。 2．由before“在……之前”和after“在……之后”引导的时间状语从句。 It will be four days before they come back．他们要过四天才能回来。 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。 After you think it over, please let me know what you decide. 你仔细考虑过以后，请告诉我你是怎样决定的。
状语从句的省略
状语从句的省略 状语从句的省略有以下几种情况： （1）在状语从句中如果主语与主句的主语一致，同时从句中又含有动词be则通常可省去从句中的主语和动词be，留下其余部分。 1.She stood at the gate as if （she was ）waiting for someone. 她站在门口好像在等人。 2．The woman teacher hurriedly left the classroom as though（she was ）angry. 这位女教师匆匆忙忙离开教室，好像生气了。 3.

If (it is) so，you must get back and get it．如果这样的话，你必须回去把它拿来。 4.I’11 buy a TV set if (it is) necessary．如有必要，我就买一台电视机。 5. Everything went on better than (it had been) expected．一切进展得比预料的顺利。 6. No matter how difficult(it may be)，we are determined to carry the research to the end． 不管有多困难，我们决心把研究进行到底。 （3）状语从句中的部分内容若与主句的部分内容相同，可将从句中的此部分内容省去。 1. He has no money．If (he has) any，he will give us．他没有钱，如果有，他会给我们的。 2. Some flowers shut up at night as if (they did this in order) to sleep．有些花夜间收拢，好像为了睡眠一样。 1.

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.

掌门1对1教育高中英语 时间、原因、条件状语从句 一．when, while 和as 引导时间状语从句的区别用法（一）when 的用法when 从句的A事件，相当于另一个事件B发生的时间点。（也就是说，when 从句的重点不在动作本身发生的状态，而只是把它作为一个时间点，）所以when 多数情况下用的是一般过去时，则不用正在进行时。（口头练习） When I got to the airport, the guests had left. Why do you want a new job when you have got such a good one already? (二)while 的用法 while 从句的侧重点在于描述动作正在发生的状态，（它的意思是：当while 事件正在发生的时候，另一件事如何如何。）所以，while 从句一般用的是正在进行时。而另一件事的状态根据具体情况而定。（口头练习） 1. While my wife was reading the newspaper, I was watching TV. 2. While Jim was mending his bike, Lin T ao came to see him. 从时间的角度来看，while 表示的是一段时间，是一个过程。 趁热打铁。Strike while the iron is hot.（这句话中，是说趁着铁是热的这段时间，赶紧打铁。如果换成when 意思就变了，相当于说铁只热了一下，打一下，然后铁就冷了。这显然不符合文意。） (三)as 的用法 as 从句表示的也是一件事情正在发生，另一件事也正在进行当中。as 从句用的一般不用正在进行时，而只是一般过去时。可以翻译成“边……边……”。（口头练习） As my mother sang those old songs, tears ran down her cheeks. The students took notes as they listened. as 表达的事件，往往只是主句动作发生的背景或条件时，as 只是一个次要的时间说明，常常翻译成“随着……”之意。 1. As the time went on，the weather got worse. 随着时间的推移，气候更加糟糕。 2. The atmosphere gets thinner and thinner as the height increases. 随着高度的增加，大气越来越稀薄。（少数情况下，如果强调动作正在发生，as 从句也可以用正在进行时。The sad mother sat on the roadside, shouting as she was crying. 伤心的妈妈坐在路边，边哭边叫喊。）
状语从句的省略形式
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。 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。 （2）条件状语从句 主要看一下由if引导的条件状语从句。if 意为“如果”，引导条件状语从句时，表示假如有从句的动作发生就（不）会有主句的动作发生。例如： If it doesn't rain tomorrow，we will go there by bike.如果明天不下雨，我们就骑自行车去那里。 If I get there early，I can see the doctor quickly.如果我早早地到那里，我就可以快点看病。 3）地点状语从句用法要点 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。（4）原因状语从句用法要点 常用的引导连词有because，as和since，三者的区别是：在回答问题的时候，使用because；对于显而易见的原因，常用as或since；as和since的从句常放在主句之前，而because的从句常放在主句之后。eg. Why did you go？I went because Tom told me to go. 你为何去？那是因为汤姆叫我去。 He was angry not because we were late but because we made a noise. 他很生气不是因为我们来迟了，而是因为我们弄出了声音。 As it was raining hard，we had to be indoors. 由于雨太大，我们只好呆在家里。Since you feel ill，you'd better not go to work. 既然你感觉不舒服，你最好不要去上班了。 （5）目的状语从句用法要点 常用的引导连词有so that，that和in order that译为：以便，为了，目的是。eg. Please speak more slowly so that we can make full notes. 请讲慢一点，以便我们能作详细笔记。 I shall write down your address that I may not forget. 我要把你的地址记下来，以免忘记。 I sent the letter by air mail in order that it might reach him in time. 这封信我以航空信发出，以便他能及时收到。 注：目的状语从句可以用动词不定式来替换做目的状语。eg. We work harder than usual finish it in a week. 我们比平常加倍努力工作以在一周

时间状语从句讲解与练习
when, while 和as 引导时间状语从句的用法 一、when 的用法 如果只从现象来看，when 从句用的最多的是一般过去时，而主句的时态没有限制,根据具体情况而定。 1. When he was a child he was always trying out new ideas. 他小时候就常常试验一些新的设想。 2. When she came into my room, I was just reading a book. 她走进我房间时，我正在看书。 3. Were you writing when the teacher came in? 老师进来的时候，你在写信吗？ 4. Sorry, I was out when you called me. 对不起，你打电话来的时候我出去了。 5. He was on the point of leaving when someone knocked at the door. 他正要走，这时有人敲门。 6. I thought of it just when you opened your mouth. 就在你要说话的时候，我也想到了。 7. I had hardly[scarcely] closed my eyes when someone knocked at the door. 我刚一闭上眼，就有人在敲门了。
根据以上的例句，我们可以总结出一点：when 从句的A事件，相当于另一个事件B发生的时间点。也就是说，when 从句的重点不在动作本身发生的状态，而只是把它作为一个时间点，所以when 多数情况下用的是一般过去时，则不用正在进行时。因为如果用正在进行时，它表示的就是一段时间而不是一个时间点了。根据这一点，有的文章补充说：when 从句的动词大多是瞬时动词。 实际上，when 从句也可以有其它的时态，但几乎也不用进行时，因为它也只是作为一个时间参照点。 1. When I got to the airport, the guests had left. 当我赶到飞机场时，客人们已经离开了。 2. When he had finished his homework, he took a short rest. 当他完成作业后，他休息了一会儿。 3. Why do you want a new job when you have got such a good one already? 你已经找到如此好的工作，为何还想再找新的？ 4. You shall borrow the book when I have
