时间、地点、原因、目的、结果、条件、行为 方式、比较、让步 等九种状语从句。一般位于 句首或者句末，位于句首，用逗号和主句格开。

地点 原因 目的 结果/程度 条件 比较 让步
考点（1）when, as, while 引导时间状语从句 When既可引导持续动作，又可引导短暂动作。它表示主 句动作和从句动作同时发生，或从句动作在主句动作之前。
When I was a boy, I used to go to the seashore on Sundays.（同时） When the lesson was over, we began our writing.（从句动作在前）
while指“在某一时间里”，“在… 期间”，从句动作必 须是持续性；也强调主句和从句动作的同时发生，往往侧 重主从句动作的对比。
While he was in London, he studied music.
as常和when, while通用，但侧重主句和从句的动作同时 发生，说明两种正在发展和变化的情况。
He hurried home, looking behind as he went. I saw your sister as she was getting on the bus yesterday. He sang as he walked.
______ he left school at fourteen, he began to train as an engineer. A. While B. Since C. When C. Then ______ the day went on, the weather got worse. A .With B. Since C. While D. As 当when, as, while表示“在…一段时间里”，主从句的动 作同时发生时，可以换用。如： While (When或As) we were discussing, Mr. Smith came in.
When 和while 引导时间状语从句时，若主句的主语和从 句的主语一致的时候，可以用when/while+现在分词表示。
____ a young man, he went to France for French.
A. When B. While C. As D. Since
Don’t be afraid of asking for help_____ it is needed. A. Unless B. since C. although D. when when和while还可以是并列连词，意思分别是“就在这 时”，“然而”。如： He was about to tell me the secret____ someone patted him on the shoulder. A. as B. until C. while D. when I do every single bit of housework____ my husband Bob just does the dishes now and then. A. since B. while C. when D. as Jasmine was holidaying with her family in a wildlife park ____she was bitten on the leg by a lion. A. when B. while C. since D. before
考点2 表示时间的词组引导状从 as soon as, no sooner…than…,hardly (barely, scarcely) …when…等用法都表示主从动作相继发生。 hardly和no sooner放在句首，从句要倒装。 例：Hardly had she sat down when the telephone rang. Immediately, instantly，the moment，the instant, the minute, the second，the day (the + 瞬时名词/段时 名词) 等 表示时间概念的词也可引导时间状从。 例： I went to see him immediately I heard from him. by the time, each time, every time, any time, last
--- Did you remember to give Mary the money you owed her? --- Yes, I gave it to her ______ I saw her. A. for the moment moment D. while B. the moment C. at the
考点3 until/ till 主句谓语动词是持续动词，“直到…为止”。如： I worked till (until) he came back. not…until…: “直到…才”,主句谓语动词必须是短暂性 的 如： She won’t go to bed till/until he returns home. not…until结构若在强调句中成为被强调的部分，须将 not 和until连在一起并前移，如果not until在句首，主句倒

几个极易混淆的时间状语从句： It was +时间点+when…（当的时候时间是） It was 5 am when we arrived at the village. It was/will be+时间段+before…(没过…就／过了…才) It was/will be two weeks before we met/meet again. It is /has been +时间段+since…（自从…以来有…） It is/has been 3 years since we last met. 突破点：一看be动词的时态，二看时间段还是时间点。 注意：在“It is /has been +时间段+since…”句型中，从句 的动词必须是短暂性的，如果是延续性的动词，时间要从 从句的动作结束时算起。如： It is 3 years since I smoked.( 我戒烟有三年了)
注意： 时间状语从句中谓语动词不能用任何一种将来 时，只能用现在时和过去时表示将来时。
where/wherever 引导，要注意 where there 连用的某些情 况下，使得地点从句更像是一个条件句。 例如： Where there is a will, there is a way.

考点1：because, as, since, for引导原因状从的区别。 because 表示的原因因果关系很强, as 和 since表示已知的 或比较明显的原因，译为“由于”“既然”，since 比 as 更正式，as 从句有时候可以倒装。 1. 在强调句中强调原因状语从句，只能用because引导， 不可用as或 since，如： It was because he was ill that he didn’t go with us. 2. because可以引导表语从句,而 as, since不可以，这时状 语一 般都是it, this, that 如：It’s because he is too lazy. 3. Tired as he was, he went to bed early. (倒装表示原因) as 也可以引导让步状语从句，具体意义由上下文表明。 4. *for也有“因为”之意，是并列连词，语气较强。常用 来补充说明原因或用来表示推断的依据，前面常带逗号。 如： It must have rained last night, for the ground is wet．
