各种状语从句的简化方法:

1 .以after 和before 引导的状语从句的主语若与主句主语一致时， 从句等于after/before+doing sth.

作状语。

例： After she sang she left the rich man's house = After singing , she left the rich man's house 2. 以as soon as 引导的状语从句的主语若与主句主语一致时，从句等于 on+doing sth.作状语，此 时的动词为非延续性动词。

例： Mary began to operate on the wounded soldiers as soon as he arrived at the village =Mary began to operate on the wounded soldiers on arriving at the village

3. 时间状语从句和条件状语从句的主语和主句主语一致时，有时可简化为不定式作状语。 例：She stopped when she saw her husband = She stopped to see her husband If you want to understand the farmers you must go to the countryside =To understand the farmers you must go to the countryside

4. 结果状语从句和目的状语从句的主语与主句主语一致时， 可以简化为不定式作状语；若两者主 语不一致时，则应简化为不定式的复合结构作状语。

例：He was so tired that he could n't go any further = He was too tired to go any further:

I came here so that I could ask some questions= I came here （i n order ） to ask some questions 5. 以when, while 引导的时间状语从句和以if 引导的条件状语从句的主语若与主句主语一致时， 从句

as （当 .....的时候，一边 .... 一边 .... ）

till/until （直到） hardly …when …刚 .... 就）

.较状语从句

等于when/while/if+doing sth.作状语，表示谓语动作发生在该状语动作的进行过程之中。

例：When he turned on the radio he found it broken. = When turning on the radio, he found it broken. While she was walking along the street she was hit by a car = While walking along the street，she was hit by a car.

6. 原因状语从句的主语与主句主语一致时，可简化为分词短语作状语。

例：Since I did n't know Chin ese, I tried to speak to her in En glish. = Not knowing Chin ese, I tried to speak to her in En glish

注意：形容词短语也可作表示原因的状语，来代替原因状语从句，放在句首、句末均可，但一般应加逗号。

例: As he was thirsty and eager to get a little rest he went into the tea-house =Thirsty and eager to get

a little rest he went into the tea-house

7. 在时间、原因、条件等状语从句中，若从句和主句主语不一致时，可简化为分词复合结构作状语。有时也可简化为“with/without名词或代词十分词（短语）'形式作状语。

例: When the film start appeared, the children got exited = The film start appearing，the children got exited .

If all the work is done, you can have a rest = With all the work done，you can have a rest Nothing can live if there is no air . = Nothing can live without air .

=Fac ing the death，he did n't say anything before the en emy.

=In spite of dan ger, he rushed out to carry the boy to safety

hardly/scarcely…when/before, no soon er-tha n 和as soon as都可以表示"一…就…"的意思, 例: I had hardly / scarcely got home when it began to rain.

I had no sooner got home tha n it bega n to rain.

As soon as I got home, it bega n to rain.

注意：如果hardly, scarcely 或no sooner置于句首，句子必须用倒装结构：

Hardly / Scarcely had I got home when it began to rain.

No sooner had I got home tha n it bega n to rain.

四.As引导的让步状语从句的倒装:

1. 形容词+as+主语+系动词：
