状语从句教讲解和习题练习(含答案)

高中英语——状语从句

一、 考点、热点回顾

状语从句在句中作状语，可分为：时间、条件、让步、原因、目的、结果、比较、地点、方式状语从句。

（一）时间状语从句

引导时间状语从句的连词有：when, as, while, until, not…until, before, after, since, the minute, the moment,

1． When , while, as都可解释为“当```的时候”但侧重点有所不同。

1) When

Eg: When I arrived home , I had a little rest.

注意点：

when 从句的主语与主句主语相同，谓语动词是be 动词时，从句主语和be可以省略。

Eg: When (she was) walking along the street, she met her class teacher.

2) As

As 除了表示“当```的时候”，还可表示为“一面```一面”，“随着”

Eg: He sang as he danced.(一面```一面)

You will grow wiser as you grow older.(随着)

3) While表示“当```的时候”强调主句的动作和从句的动作同时发生，从句一般用进行时，从句动

词必须是延续性动词。

Eg: While we were working, they were having a rest.

While (they were) having a discussion, they got very confused.

注意点：

while 有对比的含义，解释为“然而”。

eg: I prefer black tee, while he likes coffee.

2． until, not…until表示“直到```才”,在肯定句中主句常用延续性动词；在否定句中主句常用短暂

性动词。

肯定句：I waited until midnight.

否定句：I did not leave until midnight.

注意点：

1）not until…在句首，主句用倒装

eg: Not until you had explained how did I manage to do it.

2) It is not until…that…引导的强调句

It was not until it was dark that he came back.

3. the minute, the moment, each time都可表示“一```就```”

eg: The worker recognized the type of the machine the moment he saw it.

注意点：

the minute, the moment, each ( every, next, the first) time作连词不和when 连用。

4．Hardly/scarcely…when, no sooner…than, as soon as表示为“一```就```”

eg: I had hardly/scarcely got home when it began to rain.

I had no sooner got home than it began to rain.
