条件状语从句英语语法大全
条件状语从句英语语法大全条件状语从句条件状语从句是由引导词if或unless引导的从句。
例如：1.如果明天不下雨，我们就去远足。
2.如果你努力研究，就会取得好成绩。
3.除非他也去，否则我不会去参加聚会。
4.如果你不马上走，你将会迟到。
（如果你不走，你会迟到。
）在英语中，条件是指某一件事情实现之后（状语从句中的动作），其它事情（主句中的动作）才能发生，通常译作“假如”。
需要注意的是，在含有条件状语从句的复合句中，表示将来时态时，主句要用一般将来时态，从句要用一般现在时、祈使句或情态动词，即主将从现原则。
主将从现并不是指将来时，而是表示将来的含义，与if后的从句相呼应。
条件状语从句类型if是条件状语从句最常用的连词，表示在某种条件下某事很可能发生。
例如：1.如果你请他帮忙，他会帮你的。
2.如果你考试不及格，你会让他失望。
if引导的条件状语从句既可以将从句放前面，也可以将从句放后面。
例如：“如果天下雨，我们就不玩了”可以转化为“We will。
playing if it rains.”此外，if从句还可以表示不可实现的条件或根本不存在的条件，即一种虚拟的条件或假设，从句多用一般过去时或过去完成时。
例如：表示可能实现的条件，主句用一般将来时，从句用一般现在时。
例如：If it rains tomorrow。
we will stay at home。
如果明天下雨，我们会待在家里。

I would travel around the world。
如果我有更多时间，我会周游世界。
虚拟结果句则表示与现实相反的结果，主句用过去时，从句用would/could/might+动词原形。

）No sooner had he reached home than it began to rain.他刚到家，天就开始下雨了。

注意当no sooner, hardly, scarcely不放在句首时，主句不倒装，如：I had no sooner reached the bus stop than the bus started.我刚到车站，车就开走了。

2. when, while, as引导时间状语从句1) when的用法①when既可指时间点，也可指时间段（即：从句动词可以是短暂的也可是延续的）；主从句动作可同时也可先后发生。
I was thin when I was a child.当我是个孩子的时候,我很瘦。
It was raining when I arrived.我到达时，天正在下雨。
②在when引导时间状语从句时，如果从句主语与主句主语相同或为it，且从句有be动词，则从句可省主语和be动词，如：When (you are) in trouble, you can visit this man.当你有麻烦时，可以找这个人。
She is always listening to music when（she is) doing her homework. 当她做作业时，总是听音乐。

强调某一段时间内发生主句动作，相当于during the time that....My mother was cooking while I was doing my homework.当我在做作业时，妈妈在做饭。

注意 while除引导时间状语从句外，还引导对比句，作“然而”讲；并可在句首引出让步状语从句作“虽然···但”讲。

While he has his own car, he often uses mine.尽管他自己有车，他却常用我的。
3) as的用法① as引导时间状语从句时常可和when换用，但较强调同时发生，多指短暂动作。

② as还可说明两种正在发展或变化的情况，“随着...”的意思，表时间的推移。
如：As I get older, I get more optimistic.随着年龄的增长，我变得更加乐观。
③as表“一边…一边…”，引出伴随动作。
He hurried home, looking behind as he went.他匆忙地回家，边走边往后看。
④用以强调两个动作紧接着发生。
As he was going out, it began to rain.当他出去的时候，天开始下雨了。
⑤as有时引出一个名词，相当于一个时间状语从句。

Before they got to the bus stop, the bus had gone.在他们到达公共汽车站之前，公共汽车已经走了。
②在“It be + 时间段 + before从句”句型中，肯定句译成“…（之后）才”，否定句译成“…就”。
该句型有一般过去时、过去将来时、一般将来时三个时态，且有否定句。

▲before可译成“趁着还没”I'll write it down before I forget.趁着还没忘我要把它写下来。
4. until和till1)“延续性动词肯定式+until”表示“动作延续到…为止，”译为“直到…为止”，如：I waited for him until he came back. 我一直等到他回来。
2)“终止性动词的否定式+ until”表示“直到···才”。
