状语从句讲解和练习(20200526003646)
状语从句
状语从句修饰主句/主句的谓语。一般有九大类：表示时间、地点、原因、目的、结果、条
件、让步、比较和方式等。
时间状语从句
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。
6. 用until / till引导：until / till表示“直到……”。如：
He waited until she was about to leave. 他等着一直到她准备离开。
I watched him until he disappeared in the distance. 我瞧着他直到他在远处消失。
这类句型的主句动词通常只能是延续性动词，不能是终止性动词。但是，在否定句中，主句
句式，意为“直到……才……”。如：
动词可以是终止性动词，此时构成not…ntil [till]…
She didn’t marry until she was over fifty. 她直到五十多岁才结婚。
We’d better not go until your sister arrives. 我们最好等你姐姐到了再走。
7. 用since引导：since表示“自从……以来”。如：
We have known each other since we were children. 我们从小认识。
They’ve moved twice since they got married. 他们结婚后已搬了两次家。
这类句子的主句通常用现在完成时。但是，当主句表示一段时间时，可用一般现在时代替现在完成时。如：
It’s a long time since we met last. 好久没见面了。
How long is it since you came in London? 你来伦敦有多久了?
地点状语从句
地点状语从句多由where或wherever引起：
Winters were very long where he lived．在他住的地方冬天很长。
I’m standing where the brook and the river meet．我站在小溪与大河汇合处。
He left the camera where it was．他把相机留在原来的地方。
Wherever he went，he took her with him．不管他到哪里，他都带着她。
Sleep wherever yon like．你高兴在哪里睡就在哪里睡。
You can sit anywhere you like．你爱坐哪就坐哪儿。
Everywhere I go，I find the same result．不管我到哪里我都得到同样的结果。
原因状语从句：
原因状语从句多由because，as，since，seeing(that)，considering that等连词引起：
You only do it because you have to．你这样做只是因为不得不如此。
As he had been up since 4 a.m.，he was very tired．由于他清晨四点就起床了，他十分疲倦。
He can’t come with us since he’s ill.由于生病他不能和我们一道去。
Stay in bed longer today，seeing that you were late last night.昨夜你睡得晚，你今天多睡一会儿。Considering he’s only been learning English a year he speaks it very well.考虑他学英语才一年，他英语是讲得很好的。
Now that you have the chance you had better avail yourself of it.既然你现在有了机会，你最好加以利用。
目的状语从句
表示目的状语的从句可以由that（以便），so that（以便），in order that（为了；以便），Lest（免得；唯恐），in case(以防)，for fear that（生怕；以免）等引导。
为了获得他人的赞美，穿上了Lucy puts on her new skirt that she can receive others’ praise.Lucy
她的新裙子。
Mr Black eats four bowls of rice a day so that he can keep strong.为了保持强壮，Mr Black每天吃四碗饭。

Lee takes more money in case the price of items is too high.以防物价太高，Lee带了很多钱。
He ran home as fast as he can for fear that it rains.他飞快地往家跑，生怕下雨。
结果状语从句
结果状语从句表示主句动作的结果，通常由so…that…或such…that…引导，例如：
a) I am so angry that I cannot speak a word. 我气的说不出话来。
b) I am such an angry man that I cannot speak a word. 我气的说不出话来。
细心的同学一定发现，so…that…和such…that…之间的微妙区别了吧？So后面加形容词或
副词，而such后面要加名词或名词词组。例如：
a) He is so young that he can't go to school.他还太小不能上学。
b) He is such a young boy that he can't go to school.他还太小不能上学。
除此之外，so that也可以引导结果状语从句，例如：
a) I got up late this morning so that I missed the bus. 我早上起晚了，没看上公交。
有时候，so that可以省略其中的so或that。例如：
a) I got up late this morning so I missed the bus.
b) I got up late this morning that I missed the bus.
条件状语从句
常用引导词：if, unless, as/so long as 只要, only if只要, providing/provided that 假如, supposing that, in case that, on condition that。
条件状语从句的基本用法
1、用if引导：if意为“如果”。
考试作弊必予追究。
例句：If you cheat in the exam you’ll never get away with it.
2、用unless引导：unless的意思是“如果不”“除非”。
例句：Unless you go at once you will be late. 如果你不马上走，就会迟到的。
3、用as [so] long as引导：as [so] long as的意思是“如果”“只要”。
例句：I’ll remember that day as long as I live. 只要我活着，我就不会忘记那个日子。
4、用in case引导：in case用连词引导条件状语从句时，其意为“如果”“万一”。
例句：In case I forget, please remind me about it. 万一我忘记，请提醒我一下。
5、条件状语从句的时态：当主句为将来时态或含有将来意义时，条件状语从句习惯上要用
一般现在时表示将来意义，而不能直接使用将来时态。
不知道明天是
eg. I don’t know if it will rain tomorrow. But if it rains tomorrow, I’ll stay at home.否会下雨，但要是下雨的话，我就呆在家里。
让步状语从句
引导让步状语从句的连词主要有以下这些：though,although,while,as; even if,even though;
whether...or...; no matter+疑问词，疑问词-ever，regardless of+名词/名词短语/名词从句，
despite，in spite of。
① though，although：“虽然，纵然”，这两个连词意思大致相同，在一般情况下可以互换使
用。在口语中，though较常使用，although比though正式，二者都可与yet，still或nevertheless
连用，但不能与but连用。
eg. I will go to school though it's too late now.
Although he was exhausted, he(still) kept on working.
Although/Though he is very old, (yet) he is quite strong.
② as（though）：“虽然…但是”，“纵使…”，as引导的让步状语从句必须以部分倒装的形式
出现，被倒装的部分可以是表语、状语或动词原形，though也可用于这样的结构中。
eg. Object as/though you may, I’ll go.(=Though/Although you may object, I’ll go.) Fast as you write, you can’t finish your paper in only one night.
Lover of towns as I am, I realize that I owe a debt to my early country life.
③ whether：“无论，不论，不管”，由这一个复合连词引导的让步状语从句旨在说明正反两
方面的可能性都不会影响主句的意向或结果，所以它的语气是比较强烈的。
eg. You'll have to attend the ceremony whether you're free or busy.
Whether you believe it or not, it's true.
Whether or not you like her, you have to become her husband.
④ no matter+疑问词=疑问词-ever：“……都……；不管……都……”
eg. No matter what happened, he would not mind. =Whatever happened, he would not mind.
⑤ whether...or...：“不论是否……”，“不管是……还是……”
eg. Whether you are rich or poor, the end result is the same, death
比较状语从句
引导比较状语从句的从属连词为as...as，not as/so...as，than，the more...the more 等等，这些都是用来进行比较对比，并且通常会与比较级最高级等连用。
The work is not so difficult as you imagine这个工作不像你想的那么难。
He is as handsome as that film star.他跟那个电影明星一样帅。
The more you study, the more knowledge you can get.你越学习就越能懂更多。
方式状语从句
引导方式状语从句的从属连词有as，as if 或as though等, 但和比较状语从句不同，方式状
语从句的“像”“如同” 并不是表示单纯的比较，而是带有比喻或者依照的含义。
eg. Do as I told you.按我告诉你的那样做。
I remember the whole thing as if it happened yesterday. 整个这件事我记得很清楚，就仿佛是昨天发生似的。
As water is to fish, so air is to man.我们离不开空气，犹如鱼儿离不开水。
* 口语中like也可用连词引导方式状语从句。
eg. Do it like I do. 照我这样做。
我没她舞跳得好。
I can’t dance like she does.

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：
