(课件网) 状语从句 一、状语从句的类型及关联词 状语从句根据其用途可分为时间状语从句、地点状语从句、原因状语从句、目的状语从句、结果状语从句、条件状语从句、让步状语从句、方式状语从句、比较状语从句九种。 时间状语从句:由 when, as, while, whenever, after, before, until / till, as soon as, since, once, directly, immediately, by the time, every time, the moment, the minute, no sooner ... than, hardly ... when等引导。 地点状语从句:由 where, wherever, anywhere, everywhere等引导。 原因状语从句:由 because, since, as, now that, seeing that, considering that, in that等引导。 目的状语从句:由 so, so that, in case, in order that, for fear (that)等引导。 结果状语从句:由 so (that), so ... that, such ... that, with the result that等引导。 条件状语从句:由 if, unless, so / as long as, only if, provided, on condition that, in case, suppose / supposing (that)等引导。 让步状语从句:由 although, though, even if / though, as, whether ... or,“疑问词+ ever”构成的复合词,“no matter +疑问词”等引导。 方式状语从句:由 as, like, as if / though, the way等引导。 比较状语从句:由than或as引导。 二、常用关联词注意事项 1. when (1) when引导时间状语从句时,从句的动作既可与主句的动作同时发生,也可先后发生。如: When he looked back, the woman had disappeared. Don't get excited when you talk. (2) when还可引导条件状语从句,意为“如果”。如: No one can make a dress when they haven't learned how. 2. while (1) while引导时间状语从句时,从句的谓语一般是延续性动词(如work, stay, wait, live等)。如: While you are sorting your things upstairs, I'll pack my books. (2) while 引导让步状语从句时,相当于 although / though。while和although引导的让步状语从句不用倒装语序,though 引导的让步状语从句可以倒装也可以不倒装。如: While / Although / Though I admit that the problems are difficult, I don't agree that they cannot be solved. Happy though the little girl is, she will feel homesick at the beginning. 3. until和till (1) until和till都表示“直到”,常可互换,但till一般不用于句首。如: He determined to stay at the office till / until his year was up. Until I was 21, I never missed attending night school four nights a week. (2) until / till从句与肯定的主句连用时,主句的谓语动词一般是延续性动词,表示主句的动作一直持续到until / till所表示的时间为止。如: Julie stayed up till / until eleven o'clock last night. (3) until / till从句与否定的主句连用时,主句的谓语动词是非延续性动词,表示“直到……才”,即主句的动作到 until / till 所表示的时间才开始。如: I cannot comment further until / till I have all the information. (4) not until后跟从句位于句首时,主句需部分倒装。如: Not until the war was over was Einstein able to return to his homeland. 4. as (1) as引导时间状语从句时,表示“当……时;随着”。如: A look of surprise came into Allison's eyes as she read the message. As I knew him better, I discovered that my impressions had been right. (2) as引导原因状语从句时,一般放在句首,表示十分明显的原因或是已知的事实。如: As it was getting late, I decide ... ...
