状语从句讲解

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。

（一）时间状语从句

表示时间的状语从句可由when, as, while, whenever, after, before, till(until), since, once, as soon as(或the moment), by the time, no sooner … than, hardly(scarcely)… when, every time等引导。e.g.When I came into the office, the teachers were having a meeting.He started as soon as he received the news.Once you see him, you will never forget him.No sooner had I gone to bed than I went to sleep.（二）原因状语从句

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。

e.g.He is disappointed because he didn't get the position.As it is raining, I will not go out.Now that you mention it, I do remember.（三）地点状语从句

引导地点状语从句的连词是where 和wherever等。e.g.Sit wherever you like.Make a mark where you have a question.（四）目的状语从句

引导目的状语从句最常用的词（组）是so, so that（从句谓语常有情态动词）, in order that, in case（以防，以免）等。

e.g.Speak clearly, so that they may understand you.She has bought the book in order that she could follow the TV leons.He left early in case he should mi the train.（五）结果状语从句

结果状语从句是表示事态结果的从句，通常主句是原因，从句是结果。由so that（从句谓语一般没有情态动词）, so … that, such … that等引导。

e.g.She was ill, so that she didn’t attend the meeting.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

条件状语从句分真实性（有可能实现的事情）与非真实性（条件与事实相反或者在说话者看来不大可能实现的事情）条件句。引导条件状语从句的词（组）主要有if, unle, so(as)long as, on condition that, so(as)far as, if only(= if)。注意：条件从句中的if 不能用whether替换。

e.g.If he is not in the office, he must be out for lunch.You may borrow the book so long as you keep it clean.So far as I know（据我所知）, he will be away for three months.You can go swimming on condition that(= if)you don’t go too far away from the river bank.If he had come a few minutes earlier, he could have seen her.（七）让步状语从句 让步状语从句可由although, though, as, even if(though), however, whatever, whether … or, no matter who(when, what, …)等引导。注意：as引导的让步状语从句一般是倒装的。

e.g.Though he is a child, he knows a lot.Child as he is, he knows a lot.Whatever(= No matter what)you say, I’ll never change my mind.（八）方式状语从句

方式状语从句常由as, as if(though), the way, rather than等引导。

e.g.You must do the exercise as I show you.He acted as if nothing had happened.（九）比较状语从句

比较状语从句常用than, so(as)… as, the more … the more等引导。

e.g.I have made a lot more mistakes than you have.He smokes cigarettes as expensive as he can afford.The busier he is, the happier he feels.（十）使用状语从句时要注意的几个问题

1、在时间和条件（有时也在方式、让步等）从句中，主句是一般将来时，从句通常用一般现在时表示将来。

e.g.We’ll go outing if it doesn’t rain tomorrow.I’ll write to you as soon as I get to Shanghai.2、有些时间、地点、条件、方式或让步从句，如果从句的主语与主句主语一致（或虽不一致，是it），从句的谓语又包含动词be，就可省略从句中的“主语 + be”部分。

e.g.When(he was)still a boy of ten, he had to work day and night.If(you are)asked you may come in.If(it is)neceary I’ll explain to you again.3、注意区分不同从句：引导的是什么从句，不仅要根据连词，还要根据句子结构和句意来判别。以where为例，能引导多种从句。

e.g.You are to find it where you left it.（地点状语从句）

Tell me the addre where he lives.（定语从句，句中有先行词）I don’t know where he came from.（宾语从句）

Where he has gone is not known yet.（主语从句）

This place is where they once hid.（表语从句）

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。

例题解析：举一反三，学的更轻松！

易混引导词while, when, as的区别：

when既可以指“时间点”,与瞬间动词连用，也可以指“时间段”，与延续性动词连用（=while）。如：

When he came in, his mother was cooking.When(While)we were at school, we went to the library every day.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。

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 pa the exam.练习与巩固：熟能生巧，取得好成绩！选择合适的连接词，完成下列句子。
