状语从句的用法讲解 一、概述 状语从句(adverbial clause)在句中作状语，可修饰主句中的动词、形容词和副词等。状语从句由从属连词引导。状语从句可放在句首或句末。放在句首时，从句后面常用逗号；放在句末时，从句前面往往不用逗号。 When the plane arrived, some of the detectives were waiting inside the main building while others were waiting on the airfield. 当飞机抵达时，一部分侦探等在主楼里面，而另一部分则等在停机坪上。 When I came home， my wife was cooking dinner. 我回家时，妻子在做晚饭。 Though he was poor， he was happy. 虽然他很穷却很快乐。 If you ask him, he will help you. 如果你向他请求，他会帮助你。 Since you ask, I will tell you. 你既然问，我就告诉你。 I cant tell you when you wont listen. 既然你不想听，我就不告诉你了。 He stopped trying, when he might have succeeded next time. 他不再试了，其实他可能下一次就成功。 二、引导状语从句的连词分类 状语从句根据它们的含义分为时间、地点、原因、目的、结果、方式、让步、条件、比较等九种。 状语从句 连词 时间 when, whenever, as, since, till, until, before, after, as soon as, once, the moment, immediately, the day, no sooner … than, hardly(scarcely)… when, the minute, the second, every(each) time 地点 Where, wherever, everywhere 条件 if, unless, providing/provided that, as(so) long as, on condition that, suppose/supposing that, in case, only if, if only 原因 because, since, as, now that, seeing that, considering that, in that, in view of the fact that(鉴于) 让步 though, although, even if(though), as, while, whatever, wherever, whoever, however, no matter +wh词，for all that, granting/granted, whether … or, in spite of the fact that, despite the fact that 比较 as…as, not the same as, not so…as, than 方式 as, as if(though) the way 目的 that, so that, in order that, in case, for fear that, lest 结果 so that, so… that, such … that, but that 三、时间状语从句 1、?? 引导时间状语从句从属常用连词例析 常用来引导时间状语从句的从属连词有:when(当……的时候)，whenever(每当)，after(在……之后)，before(在……之前)，as(当…… ;一边……一边)，as soon as/hardly…when/no sooner…than(一……就……)，while(在……期间)，till/until(直到)，since(自从)，once(一旦……就……)。如果主句是一般将来时，在时间状语从句中用一般现在时。since 所引导的从句一般要用非延续性动词，主句用完成时态。 Don’t be afraid of asking for help when it is needed. 如果你需要时别不敢求援。?
