状语从句讲解与练习
状语从句讲解与练习一、时间状语从句定义：用从句来表达一件事情或一个行为发生的时间(一) before & afterbefore：“在……之前”，主句动作发生在从句动作之前[主前从后]after：“在……之后”，主句动作发生在从句动作之后[主后从前]He called me after he finished his homework.He had learned English for three years before he went to London.(二)as soon as 一……就…… [主将从现]表示从句动作一发生，主句动作马上就发生。
I'll tell her everything as soon as she comes back.As soon as I reached Canada, I rang him up.(三) since 自从(1) 主句【现在完成时】+ since时间状语从句【一般过去时】He has gone abroad since he was 20.(2) It’s + 一段时间+ since时间状语从句【一般过去时】It is 10 years since we became friends.(四) until(1) 用于肯定句中，表示主句的动作一直持续到从句动作发生或状态出现时为止。
一般可译为“直到……为止”。
主句的动词必须是延续性的。
He will stay here until his mother comes back. [主将从现](2) until用于否定句中，表示主句的动作在从句的动作发生之后才开始。
一般可译为“直到……才……”或“直到……之前不要……” 。
主句的动词多为非延续性。
Don”t get off the bus until it has stopped.The little girl didn’t stop crying until she saw her mom.(五) when & while & as(1) 理论基础①三者都可表示“当……时”② while只接持续性动词，when/as持续、短暂都可以接③while 多用于进行时态，when多用于一般时态(2) 一般时while进行；进行when一般时The telephone rang while I was taking a bath.I was reading a newspaper when he came in.(3) 事件对比用while（然而；却）Father was preparing a report while I was playing PC games.He likes coffee while she likes tea.(4) “随着”/“一边…一边”用asThings are getting better and better as time goes on.She sang as she went along.二、原因状语从句because 因为（不与so连用）(1) because &because ofbecause引导原因状语从句because of 是介词短语，后跟n./pron./V-ing，句中作原因状语-- Why didn't he come here?-- He didn’t come here because he was ill.-- He didn’t come here because of his illness.(2) because & for & since & asbecause 语气最强烈；for放句中，用来表示一种附带或补充解释、说明；since & as 通常放句首，作“既然”讲。

状语从句用法讲解和练习Document number：NOCG-YUNOO-BUYTT-UU986-1986UT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:第一节时间状语从句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。
I'll go on with the work when／come back tomorrow．我明天回来后会继续做我的工作。
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：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：She thought I was talking about her daughter, while in fact, I was talking about my daughter.她以为我在谈论她女儿，而事实上，我在谈论我的女儿。
如果表示从句的动作在主句的动作“之前”或“之后”发生时，多用when（=after）, 不用as 或 while。
此外，when还含有“at that moment”的意思（= and then），引起的句子不能放在句首，也不能用as, while来替换。
例如：He was about to leave when the telephone rang.他正要离开，忽然电话铃响了。
We were watching TV when suddenly the lights went out.我们正在看电视，突然灯灭了。
They had just arrived home when it began to rain.他们刚到家，天就开始下雨了。
3．till／until，表示“一直到……”，主从句都用肯定式；表示“直到……才”，主句否定，从句肯定。
He worked until it was dark. 他一直工作到天黑。
He did not get up till his mother came in. 一直到母亲进来他才起床。
4．once“一旦”，by the time“到……时”。
Once you see her, you will find what I said is true. 一旦你见到她就会发现我说的是对的。
by the time+现在时，主句用将来完成时。
By the time he arrives, we will already have left here. 等他到达时，我们将已离开这儿了。
by the time+一般过去时，主句用过去完成时。
By the time he arrived, we had already left here.他到达的时候我们早已离开这儿了。
5．as soon as，the moment表示从句动作一发生，主句动作随即发生，通常译为“一……就”。
As soon as I finish the work, I'll go to see you. 我一完成工作就会来看你。
She came to the scene the moment she heard the news.她一听到消息就来到现场。
6．since“自从”，before“在……前”，after“在……后”，It was not long before意为“不久”。
since引导从句用非延续性动词或“过去时间点”或“过去时间段+ago”，主句用完成时态。
Since he graduated, he has worked in this city. 他毕业后一直在这个城市工作。
I haven't seen him since last year/ three years ago. 去年以来/3年来，我没见过他。
