初中英语状语从句讲解、练习与答案
初中英语状语从句讲解、练习与答案状语从句是用来修饰主句中的动词、副词和形容词的从句。
根据其含义，状语从句可以分为时间状语从句、地点状语从句、条件状语从句、原因状语从句、结果状语从句、比较状语从句、目的状语从句和让步状语从句。
时间状语从句通常用when、as、while、before、after、since、till、until、as soon as等连词来引导。
例如：昨天我到学校时，正下着大雨。
他正在做作业时，电话响了。
他沿着湖边走着，快乐地唱着歌。
他来中国之前学了一点中文。
他中学毕业后，去了一家工厂工作。
在时间状语从句中，通常不使用将来时态，而是用现在时态表示将来的动作或状态。
例如：我到纽约后会给你打电话。
他回来时，我会告诉他一切。
他不看到实物，是不会相信的。
在带有till或until引导的时间状语从句的主从复合句中，如果主句用肯定式，其含义是“一直到……时”，谓语动词只能用延续性动词。
如果主句用否定式，其含义是“直到……才……”、“在……以前不……”，谓语动词可用瞬间动词。
例如：年轻人读书直到灯熄灭。
让我们等到雨停。
XXX来之前我们不会开始。
在公交车停下之前不要下车。

在固定组合中，XXX和till/until是不能互换的。
条件状语从句通常由if或unless引导。
谓语动词通常用现在时态表示将来的动作或状态。
例如，如果我明天有空，我会帮你学英语。
他不会迟到，除非他生病了。
同时，“祈使句+ and (or)+陈述句”在意思上相当于一个带有条件状语从句的复合句。
原因状语从句通常由because、since或as引导。
其中，XXX表示直接原因，语气最强，常放在主句之后。
而as和since语气较弱，一般用来表示明显的原因，常放在句首。
例如，他没来上学是因为他生病了。
由于现在下雨，我们不应该去动物园。

1. 时间状语从句(1)时间状语从句常用when, as, while, before, after, since, till, until, as soon as等连词来引导。
例如：It was raining hard（rain hard 下大雨）when got to school yesterday.While he was doing his homework, the telephone rang.As he walked along（沿着走）the lake, he sang happily.He had learned a little Chinese before he came to China.After he finished middle school, he went to work in a factory.(2)在时间状语从句里，通常不用将来时态，用现在时态表示将来的动作或状态。
例如：I’ll ring you up as soon as I get to New York.I will tell him everything when he comes back.He won’t believe it until he sees it with his own eyes.(3)在带有till或until引导的时间状语从句的主从复合句里，如果主句用肯定式，其含义是“一直到……时”，谓语动词只能用延续性动词。
如果主句用否定式，其含义是“直到……才……”, “在……以前不……”, 谓语动词可用瞬间动词。
例如：The young man read till the light went out（熄灭）.Let’s wait until the rain stops.We won’t start until Bob comes.Don’t get off（从下来）until the bus stops.【Till是指直到某一特定事件发生的时候，而在那个时刻之后，该事情或状况仍将持续。

初中英语语法专题讲座——状语从句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，as long as（长达……之久）条件 If, unless,as/so long as(只要)原因 As, because, since，as/so long as(既然,因为)地点 Where目的 So that(为了), in order that结果 So that（方便）, so…that,such…that让步 though, although, even if, however方式 As比较than, (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。
They all continued their regard for me as long as they lived. 他们毕生都在关心着我.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，（为了）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可以和延续性动词连用，也可以和短暂性动词连用；而while和as只能和延续性动词连用。
如：When he came in, his mother was cooking.When (While) we were at school, we went to the library every day.when从句的谓语动词可以在主句谓语动作之前、之后或同时发生；while和as从句的谓语动作必须是和主句谓语动作同时发生。
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。
在将来时从句中，常用when，且从句须用一般时代替将来时。
①You shall borrow the book when I have finished reading it．在我读完这本书后，你可以借阅。
②When the manager comes here for a visit next week，Ill talk with him about this．下周，经理来这参观时，我会和他谈谈此事。
when用于表示“一……就……”的句型中（指过去的事情）。
sb．had hardly（＝scarcely）done sth．when．．．＝Hardly ／Scarcely had sb．done sth．when．．．①I had hardly／scarcely closed my eyes when someone knocked at the door．＝Hardly／Scarcely had I closed my eyes when someone knocked at the door．我刚一闭上眼，就有人在敲门了。
②I had hardly／scarcely entered my room when the telephone rang．＝Hardly ／Scarcely had I entered my room when the telephone rang．我刚一走进房门，电话就响了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.3．such…that, so…that, so that 引导结果状语从句的区别：such是形容词，修饰名词; so 是副词，修饰形容词或副词。
其结构如下：1) such + a (n)+ 形容词+单数可数名词+that……2) such+形容词+复数可数名词+that ……3) such +形容词+不可数名词+that……。
如：This was such a good film that I went to see it several times.It was such good books that they sell well.It was such bad weather that I had to stay at home.He spoke so fast that I couldn't follow him.He is such a lovely boy that we all like him.=He is so lovely a boy that we all like him.注：在"形容词+可数名词复数/不可数名词"结构中，当名词前有many, much, few, little 表示数量的多少时，名词前用so。
如：She made so many mistakes that she didn't pass the exam.so that 既可以引导目的状语从句又可以引导结果状语从句引导目的状语从句时可译为"为了" ,引导结果状语从句时可译为"以便" 如I speak loudly so that all the students can hear me clearly.(目的状语从句)Maria likes the woolen dress so that she decides to buy it immediately .(结果状语从句)(1)so that引导目的状语从句时表示“以便为了”从句中常使用can /could /may/might /will /would /should等情态动词或助动词引导结果状语从句时从句中一般不用can 和may等词。
(2)So that引导的目的状语从句之前不用逗号而so that引导的结果状语从句与主句之间往往有逗号相隔开即略作停顿意思是“因此;所以”。
请比较He worked hard at his lessons so that he could gain high grades in the exams.他努力学习功课争取考试能获得好成绩。
He worked hard at his lessons, so that he gained high grades in the exams.他努力学习结果考试获得了好成绩。
