状语从句

状语从句是一个有主谓结构的完整句子在主句中修饰动词或整个句子充当状语的从句，可表示时间、地点、原因、目的、结果、条件、让步、方式和比较等。高考的重点是：时间、让步、地点、条件和目的状语从句。其特点是：从属连词有一定的意义，根据主句和从句的逻辑关系来确定连词。

Take an umbrella ____ it rains.

A. unless

B. in case

C. Though

D. after 一、时间状语从句

常用的连词有：when, as, while, whenever, after, before, not… until (till), since, once , as … as, the moment (minute), by the time, no sooner… than, hardly… when, every time (next time ),

1.when

while

as 有几种情况要用when be doing sth…..

when;

be just about to do…. when ;

had done…when; hardly/scarcely….when ; be on the point of doing sth….when

while 从句中常用进行时态或表状态延续的动词，用while时也可用

when代替。

He phoned me while (when) I was having lunch.

as 表示主句和从句的谓语动词动作同时发生, 表”随…而发生”时只用as. He sang as he worked. As

time goes by, we become mature. ( “with” is a preposition, we can say: With time going by, we become mature.)

2. before 由before引导的一个句型: It is / will be +一段时间+ before

从句（从句中用一般现在时或一般过去时）

It is (will be) five days before he comes here. It was/might be a few days before he came back to life. 3. not… until (till) 如果前面的谓语动词是延续性动词就不用否定not，till不放在句首。

I will stay here until you come back. I will not leave until you come back. 高考考点：

Not until you come back will I leave. It is not until you come back that I will leave. 4. since

since 所连接的状语从句中常用一般过去时，主句用现在完成时。

They have lived here since they moved here. 现在完成时也有句型：

I have taught here for ten years.（可转换为

It is (has been) ten years since I began to teach.) 这句的形式为：It is/has been+一段时间+ since从句（从句中用一般过去时）。注意before与比较。下面两句的意思一样吗？

翻译：

It is six years since he came here.

It is six years since he lived here. 5.as soon as

表示

“一…就”；

表这个意义还可用：the moment (minute), directly, immediately, instantly, hardly… when, no sooner… than,

I will tell her the news as soon as I see her. She returned the book

the moment she finished reading it. The workers went home immediately they finished their work. 有时还可用every time, each time, next time, the first time等连接时间状语从句。

Make the right choices: 1. They fell in love with each other____ they met each other. A. for the first time B. at the first time C. the first time

D. at no time 2. It began to rain

____ he got home. A. the minute

B. in a minute C. for a minute

D. at the moment

二、原因状语从句

从属连词常有：

because, since, as, now that, in that (for是并列连词，补充说明原因。）

because语气最强,常回答why的提问；我们用since

,

as表示已知的或明显的原因；

in that 意思为

“原因在于”,for放在另一个句子之后用逗号隔开，补充说明前一句的原因,连接的是并列句。

because不与so 连用。

---Why didn’t he feel disappointed?

--- Because he didn’t get the position?

Since it is raining, I’ll not go out.

Now that you mention it, I do remember. I was lucky in that I was able to find a good job. I got a cold, for I had been walking in the rain. 三、地点状语从句

地点状语从句常用连词

where, wherever 来引导。状语从句要根据句子注意体会。

目的状语从句用连词

so that, in order that, in case 来连接，从句中常有情态动词may (might), can (could)。

Speak clearly, so that they may understand you. (Speak clearly so as to understand you.) She has bought the book in order that she

could follow the lessons. (She has bought the book in order to follow the lessons. ) He left early in case he should miss the train. 五、结果状语从句

so 或

such 的区别。

She is so good a teacher that everyone respects her. 注意：

1.She is such a good teacher (so good a teacher) ____ everyone respects . 2.She is such a good teacher (so good a teacher) ____ everyone respects . Such a good teacher (So good a teacher) is she that everyone respects her.

as, while (常放在句首）等引导。
