状 语 从 句
1.时间状语从句
1)由连词when, while, as, as soon as, before, after, since, till/ until 等引导。 • 主句用将来时，从句常用一般现在 时表将来
_____ I accept that he is not perfect, I do actually like the person. A. While B. Since C. Before D. Unless Did you remember to give Mary the money you owed her? Yes. I gave it to her ______ I saw her. A. while B. the moment C. suddenly D. once

另外, when/while还作并列连词,连接并列分句, while表示 “而,可是”如: I like reading while my wife enjoys watching TV. when表示 “就在这时” 在下列结构中，表示某 件事正在发生或刚刚发生，另一动作同时发生。
1.be about to do… when… 2.be doing… when… 3.had done… when…
1)as 引导的让步从句要倒装，句型为： 形容词/ 副词/ 名词（不带冠词）/ 动词 （原形）+主语+谓语 Young as he is, he knows a lot. Much as I like it, I can’t afford it. Farmer as he is, he is well-educated. Try as I might, I couldn’t lift the stone. 2）although不倒装， though可倒装也可 不倒装, as 必须倒装

while的用法小结 ： ①While I was walking down the street, I came across an old friend. ( while when =_______) ②He likes pop music, while I am fond of folk music. ( while but ③While I really don’t like art, I find his work impressive. (while=___________) although
I will tell him when he comes back.
2)while, when, as辨析
While引导的时间状语从句只指一段时间， 强调某一段时间内，主从句动作同时发 生。从句动词常是延续性的 When既可以指一个时间点,也可以是一段 时间，可表示主从句的动作同时或先后 发生。从句动词可以是延续性的，也可 以是非延续性的。 As强调主句﹑从句动作相并发生,译为”一 边…一边…”
How long is it since you lived in Shanghai? 你离开（没住在）上海多久了延续性；不… 多长时间了 It is half a month since he was a League member.他退团（不当团员）半个月了。 It’s been quite some time since I was last in London我离开伦敦已很长时间了。 比较：He has written to me frequently since I was ill.自从我病愈以来，他屡次给我写信。 （从句谓语为状态动词） He has written to me frequently since I fell ill. 自从我生病以来，他就屡次给我写信。 （从句谓语为终止性动词）
