老师，我又忘 记什么是状 语从句了。

小新，你什么

时候会哭呢？

上面这个句子有什么特点吗？

批注：引导学生去发现这句话的特点：第一，这句话由两个完整的小句子组成，问问学生哪句话是主句，哪句话不是。其次，when作为连接词，让人想到了时间，所以结合到一起就是时间状语从句。

一、状语从句的概念

用来修饰主句中的动词，副词和形容词的从句叫状语从句。

二、状语从句的分类

根据其含义状语从句可分为时间状语从句，地点状语从句，条件状语从句, 语从句，目的

原因状语从句，结果状语从句，比较状状语从句，让步状语从句。

三、状语从句的句法功能

2 1.时间状语从句（主句将来时从句现在时）

弋殳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 when got to school yesterday.

While he was doing his homework, the telephone rang.

As he walked along 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.

易混引导词while, when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 )。While表示时间段，因此，while从句的谓语动词要用延续性动词。

练习：用while或when填空

1. Please don't talk so loud others are working.

2.he came in, his mother was cooking.

3.we were at school, we went to the library every day. Keys: 1. while 2. when 2. While

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。

2)

练习：

1.I ' ll ring you up as soon as I ( get) to New York.

2..I will tell him everything when he(come) back.

3.He won ' t believe it until he(see) it with his own eyes. Keys: 1. get 2. comes 3. sees

结论：主将从现的原则

学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"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：(注意粗体单词)

1.The young man read till the light went out.

2.Let ' wait until the rain stops.

3.We won' start until Bob comes.

4.Don' g et off until the bus stops.

① 2.条件状语从句(主句用将来时从句用现在时)

4^1)条件状语从句通常由if, unless引导。例如：

What shall we do if it snows tomorrow?

Don' t leave the building unless I tell you to.

2)在条件状语从句里，谓语动词通常用现在时态表示将来的动作或状态

练习：

1.I ' ll help you with your English if I(be) free tomorrow.

2.He (not) be late unless he is ill.

Keys: 1. am 2. will not

仇）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。例如：

Hurry up, or （其中文意思是什么）you ' ll be late.

=If you don ' t hurry up, you ' ll be late.

Study hard and you will pass the exam.

=If you study hard, you will pass the exam.

批注：需要让学生理解祈使句也是个句子，只是省略主语的句子，汉语中也较多此类句型，可以类比讲解。

陆3.原因状语从句

'了1）原因状语从句通常由because, since （因为），as （因为）引导。例如：

He didn ' t come to school because he was ill.

As it is raining, we shall not go the zoo.

Since you can ' t answer the question, I ' ll ask someone else.

4?2）because表示直接原因，语气最强。Because引导的原因状语从句多放在主句之后。回答由why提出的问题, 只能用because。As和since语气较弱，一般用来表示明显的原因。由as和since引导的原因状语从居多放在句首。例如： --- Why aren ' t going there?

--- Because I don ' t want to.

As he has no car, he can ' t get there easily.

Since we have no money, we can ' t buy it.

'l，3）because和so不能同用在一个句子里。

P 4.结果状语从句

【’I）结果状语从句由so…that, such …that, so that导。

练习：

1.He is poor that he can ' t buy a bike for his son.

A . so B. such C. much D .too

2.She is good teacher that everybody likes her.

A .such a B. so a C. a so D .a such

Keys: A A

t'2）so…that语such...that可以互换。例如：

在由so...that引导的结果状语从句中，so是副词，与形容词连用。其结构是：

“…so +形容词（副词）+ that +从句”。

例如：

He was so glad that he couldn ' t say a word.

The hall is so big that it can hold 2,000 people.

Mother lives so far away that we hardly ever see her.
