[我的发现]

(1)判断上述状语从句的类型：②⑦⑧是让步状语从句；③④是条件状语从句；①⑤⑥是时间状语从句。

(2)even though引导让步状语从句时，可用even_if来替换。

一、时间状语从句

1．when引导的时间状语从句

when引导的时间状语从句的谓语动词可以是延续性动词，也可以是终止性动词；从句的动作和主句的动作可以同时发生，也可以先后发生。

It was snowing when we got to the airport.

我们到达机场时，天正下着雪。(同时发生)

He went home when he had finished his homework.

做完作业后他回家了。(先后发生)

[名师点津] whenever意为“每当，每每”时，也能引导时间状语从句。

Larry always blames me whenever anything goes wrong.

每每什么事情出现问题，拉里总是责怪我。

2．while引导的时间状语从句

while引导的时间状语从句的谓语动词是延续性动词或表示状态的动词，并强调主句和从句的动作同时发生。

Please write while I read.

我念的时候，请写下来。

He listens to the radio while driving to work.

他去上班时一边开着车一边听广播。

3．as引导的时间状语从句

as表示“一边……一边……，随着”，as引导的时间状语从句动作是延续性的动作，一般主句和从句动作同时发生。

I hurt my shoulder as I was playing basketball.

我打篮球时弄伤了肩膀。(本句中的as 可用when 或者while替换)

4．since引导的时间状语从句

since引导时间状语从句时，表示“自从……”，从句中的谓语动词常用瞬间动词。一般情况下，从句的谓语动词用一般过去时，而主句的谓语动词用现在完成时。

He has written to me frequently since I got sick.

自从我病了以后，他经常给我写信。

5．till和until引导的时间状语从句

这两个词的用法类似，都表示“直到……才”，但till不用于句首；用于肯定句时，主句要用延续性动词，用于否定句时，主句要用非延续性动词。

I waited till/until 9：00.

我一直等到9点钟。(wait为延续性动作)

I didn't go to bed until/till my father came back.

我直到父亲回来才上床睡觉。(go to bed为非延续性动作)

6．before引导的时间状语从句

before引导时间状语从句时，意为“在……之前；……之后才；没来得及……就……”，常表示主句动作先于从句动作发生。从句一般不能为否定句。

He had put the broken vase away before his mother came back.

他趁妈妈还没回来把打碎的花瓶收拾好了。

7．after引导的时间状语从句

after表示主句动作发生在从句动作之后。主句用一般过去时，从句可以用一般过去时，也可以用过去完成时。

He called me after he had finished his work.

工作完了之后他给我打了个电话。

8．名词词组作连词引导的时间状语从句

表示时间的名词词组也可以引导时间状语从句。常见的这类名词词组有：the time, the moment, the minute, the day, the year, the first time, the second time, each time, every time, next time, any time等。

The moment he reached the country, he started his search.

他一到达这个国家，就开始他的搜寻工作。

9．表示“一……就……”的连词或结构引导的时间状语从句

as soon as, immediately, directly, instantly, no sooner ...than ..., hardly/scarcely ... when ...都意为“一……就……”，表示从句动作一发生，主句动作随即发生。

Directly you feel any pains, you must go to the doctor.

你一感觉疼痛就必须去找医生。

No sooner had she gone to sleep than the telephone rang once more.

她刚睡着，电话就又响了。

[名师点津] 注意no sooner ...than ..., hardly/scarcely ...when ...结构的时态搭配， no sooner与hardly/scarcely引导的主句谓语动词应用过去完成时，而than与when的从句中的谓语动词应用一般过去时。此外，当把no sooner和hardly/scarcely提到句首时，句子应用部分倒装语序。

10．时间状语从句的几个常用句型

(1)It is/has been＋时间段＋since ...(从句用一般过去时)“自……以来已有多长时间了”，从句谓语用短暂性动词时，表示动作持续了多久，用延续性动词时，表示动作停止了多久。

How long is it since we met last time?

自上次我们见面以来有多长时间了？

(2)It is/was＋时间点＋when ...“当……的时候已是……”。
