状语从句
由从句担任的状语，在句子中可修饰谓语（或其它动词）、形容词、副词或是整个句子，它可以用来表示时间、地点、原因、目的、结果、条件、方式、比较、让步等。状语从句是一较大的语法项目，也是近几年高考题中常见的一个重要试点。高考中已考查了时间、让步、地点、条件、目的等状语从句，这些从句仍是今后高考热点，应作充分准备。同时对方式状语从句也应引起重视。

原因状语从句是表示原因或理由的，引导这类从句的最常用的连词是because, since, as , now that（既然）等，for 表示因果关系时（它引导的不是从句）为并列连词，语气不如because强。

He was so excited that he could not say a word.
She is such a good teacher that everyone admires her.
（六）条件状语从句

10. 状语从句的简化
状语从句的省略
状语从句同时具备下列两个条件:①主句和从句的主语一致，或从句主语为it;②从句主要动词是be的某种形式。从句中的主语和be动词常可省略。例如：
When the museum is pleted , the museum will be open to the public next year .
He’ll go to the seaside for his holiday if it is possible.
另外，比较状语从句经常省略。例如：
I’m taller than he is tall .
The higher the temperature is, the greater the pressure is .
就状语从句而言,有时为了使语言言简意赅,常常将状语从句进行"简化"。状语从句的"简化"现象在口语中较为普遍,而且在高考中的复现率也较高。因此,有必要对其进行全面、透彻的了解。
状语从句的"简化"现象常存在于以下五种状语从句中:①由if, unless等引导的条件状语从句;②由although, though, even if / though等引导的让步状语从句;③由when, while, as, before, after, until / till等引导的时间状语从句;④由as, as if等引导的方式状语从句;⑤由as, than等引导的比较状语从句。下面针对这五种情形作一归纳。
1当状语从句的主语是it,且谓语动词是be时,it和be要完全简化掉。例如:
If it is possible, he will help you out of the difficulty.如果可能的话,他会帮你摆脱困境。
You must attend the meeting unless it is inconvenient to you.除非情况对你来说不方便,否则你必须出席这次会议。
2当状语从句的主语和主句的主语一致时,从句可以将主语和be动词简化掉。常用于以下几种情形:
a.连词+形容词
As he was young, he learned how to ride a bike.他小时候就学会了骑自行车。
Whenever she is free, she often goes shopping.她有空就去逛商店。
Work hard when you are young, or you'll regret.少壮不努力,老大徒伤悲。
b.连词+名词
While he was a young boy, he was always ready to help others.他在孩提时代就乐于助人。
Although he was a farmer, now he is a famous director.尽管他曾是个农民,而现在是位著名的导演了。
c.连词+现在分词
As she was walking along the river bank, she was singing a pop song.她沿着河堤边走边唱着流行歌曲。
Although he is doing his best in maths these days, he has still got no good marks.尽管近来他一直在学数学,但他仍然没有取得好成绩。
d.连词+过去分词
He won't go there with us unless he is invited.除非受到邀请,否则他不会和我们一道去那里。
The concert was a great success than it was expected.这场音乐会出乎意料地取得了巨大成功。
e.连词+不定式
He stood up as if he were to say something.当时他站起来好像要说什么。He wouldn't solve the problem even if he were to take charge.即使他来负责,他也解决不了这个问题。
f. 连词+介词短语
She looked anxious as though she was in trouble.她看上去很焦急,好像遇到了麻烦。
He had mastered the English language before he was in the USA.他到美国之前就懂英语了。
注意:当从句主语和主句主语不一致时,从句部分要么用完全形式,要么用独立主格结构来表达。例如:
When the meeting was over, all the people went out of the meeting-room.当会议结束时,人们都走出了会议室。=The meeting over
状语从句的时态特点
一般情况下，时间和条件状语从句的谓语动词一般用“一般现在时”表示“一般将来时”，用“现在完成时”表示“将来完成时”。例如：
I will call you as soon as I arrive in Beijing. 我一到北京就给你打电话。这是由as soon as引导的时间状语从句，从句中的谓语动词arrive是一般现在时，表示一般将来时，决不可用will arrive
As soon as I have finished this work, I will go home. 我一完成此工作，就回家。从句中的谓语动词用现在完成时have finished，表示将来完成时,决不可用will have finished
If he es back, please let me know.如果他回来了，请通知我。从句中的谓语动词用es back,表示一般将来时，决不可用will e back
unless = if...not.
e.g. Let's go out for a walk unless you are too tired.
If you are not too tired,let's go out for a walk.
if 引导的条件句有真实条件句和非真实条件句两种：
真实条件句
如：If it rains tomorrow,we won’t go on a park 非真实条件句是虚拟语气的一种，表示与事实相反，如：
If I were you,I would go with him.
so/as long as只要
由as (so) long as,in case引导。
So long as you’re happy,it doesn’t matter what you do.
只要你高兴，你做什么都没有关系。
You may borrow my book as long as you keep it clean.
只要你保持书的清洁，你就可以把我的书借去。
Take your umbrella in case it rains.
带着你的伞吧，以防下雨。
例句
引导条件状语从句的连词有：if（如果），unless（除非；如果不），as long as（除非；只要），supposing（假设），on condition that（条件是），in case（如果）。
例
You can't learn English well unless you work hard.
除非你努力学习，否则你学不好英语。
You can use my bike on condition that you return it by Friday.
你可以使用我的自行车，条件是你星期五以前还。
1）学习条件状语从句应注意以下几点：
⑴条件状语从句中一般不使用将来时态，尽管主句使用将
来时态，而从句用一般现在时或现在完成时。
例
I will come to see you if I have time.
我有时间，我就来看你。
If the rain stops,I shall go out for a walk.
如果雨停了，我就出去散步。
⑵注意条件状语从句在虚拟语气中的使用。
例
If I were to I should first of all get the experts to discuss the plan.
如果我真的想做这事，我首先会找专家们讨论我的计划。
⑶条件状语从句中的省略。
例
Come tomorrow if possible. 可能的话，明天来。
I will buy a DVD set if necessary.
