使用时间状语从句时要注意下列几个词:
as，while，When
as强调两个动作同时进行，动作通常是延续性的，且表示“一边……一边”；还可表示“随着时叵的推移”。例:
He always sings as he walks.
As time went on,his theory proved to be correct.
when引导的时间状语从句中，其谓语动词可以是延续性的，也可以是非延续性的，有时还表示“就在那时”。例:
When the teacher came in, the students were reading aloud.
When he stayed in America, he learned a lot of English.
We were about to set out when it began to rain.
while在……期间，引导的从句的动作是延续性的，并侧重主从句的动作同时发生；有时while还表示转折关系“而”。例:
While his mother was cooking in the kitchen, the little boy fell asleep in the chair.
He is a worker,while his sister is a doctor.
原因状语从句的引导词有:as because,since,now that 等。
如:Now that you are all here,let’s reach a decision.
注意，for是并列连词，引导的是并列句，对前述内容作补充性说明。

It is known to all that __ you exercise regularly, you won’t keep good health.
A. unless
B. whenever
C. although
D. if
【错误解答】 B
【错解分析】 很多考生认为本题应该用whenever来引导时间状语从句，事实上分析本句结构和句意可知，it实际上是替代后面从句的，句子的真正结构为:_
you exercise regularly，you won’t keep good health。因此，应该用unless，句意为“除非你经常有规则地锻炼，否则不会有好身体的”。
【正确解答】 A
【名师点睛】
结果状语从句的引导词有:so...that，such...that应该正确使用so和such
(1)so + adj.／adv.／分词 + that...
(2)so + adj + a + 可数名词单数 + that...
(3)so +
many／few／little/much + 名词 + that... 此处many／few／little／much是表示数量的形容词。
(4)such + a + adj. + 单数可数名词 + that...
(5)such + adj.+ 可数名词复数或不可数名词 + that...例:
The boy is so young that he can’t go to school.
He is such a young boy that he can’t go to school.

【错误解答】 D
【错解分析】 as though = as if，用在本句中明显不合语境，本句意为“请给孩子们发言的机会，即使他们的意见和你们的不统一”。even if 意为“即使”，符合语境。
【正确解答】 B
【名师点睛】
由“no matter+疑问词”和“疑问词+ever”引 导的让步状语从句可互换。例:
No matter what happened, he wouldn’t mind.
= Whatever happened, he wouldn’t mind.
注意:“on matter+疑问词”结构只能引导让步状语从句，而“疑问词+ever”还可以引导名词性从句。例:Whoever comes will be welcomed.

让步状语从句的引导词有:though，although， as，even if，even though，
疑问词 + ever，no matter + 疑问词，方式状语从句的引导词有：as，as if，as though。
