(雨停后,我们出去了。)while 当……期间;在……过程中 1. 强调主句和从句的动作同时发生,且持续一段时间。2. 从句谓语必须是延续性动词。 While I was sleeping, my mother was cooking. (我在睡觉的时候,妈妈正在做饭。)as 一边……一边……;随着 1. 强调主句和从句动作同时发生,且都在变化或发展。2. 表示“随着”时间推移。 As he grew older, he became wiser. (随着年龄增长,他变得更聪明了。)before 在……之前 表示主句动作发生在从句动作之前。 Please wash your hands before you have dinner. (吃饭前请洗手。)after 在……之后 表示主句动作发生在从句动作之后。 After he finished his homework, he watched TV. (他做完作业后看了电视。)since 自从……以来 1. 主句常用现在完成时,从句用一般过去时。2. 表示从过去某一点开始,持续到现在的动作。 He has lived here since he was born. (他自从出生就住在这里。)until / till 直到……为止 1. 用于肯定句时,主句谓语是延续性动词,表示动作持续到从句动作发生为止。2. 用于否定句(not...until...)时,主句谓语是瞬间动词,表示“直到……才……”。 I waited until he came back. (我一直等到他回来。)I didn't go to bed until he came back. (直到他回来我才睡觉。)as soon as 一……就…… 表示从句动作一发生,主句动作立即发生。 I will call you as soon as I arrive. (我一到就给你打电话。)三、 重点与难点1. when, while, as 的区别这是最常考的考点,关键在于从句动词的性质。引导词 动作性质 侧重点 典型句型when 可延续,可瞬间 某个时间点或时间段 when + 一般过去时/过去进行时while 必须是延续性动词 强调整个过程 while + 过去进行时as 可延续 强调“一边…一边…”或“随着” as + 一般过去时When I got home, it was raining. (get home是瞬间动作,用when)While it was raining, I was reading. (rain和read都是延续性动作,用while)As/When/While I walked along the street, I saw an old friend. (walk是延续性动作,三者都可,但含义略有不同)2. 时态问题:主将从现这是时间状语从句中最重要的时态规则。规则:当主句是将来时(或含有将来的意味,如祈使句、情态动词can/may/must等)时,时间状语从句必须用一般现在时来表示将来的动作。主句时态 从句时态(示例) 例句一般将来时 (will do) 一般现在时 (do/does) I will tell him when he comes. (他来的时候我会告诉他。)祈使句 (Do...) 一般现在时 (do/does) Please turn off the light before you leave. (你离开前请关灯。)情态动词 (can/may...) 一般现在时 (do/does) You can go out after you finish your homework. (你完成作业后就可以出去。)特别注意:when 引导的从句如果表示“当……时候”,也遵循“主将从现”原则。但如果 when 表示“那时”,引导的是宾语从句,则时态不受此限制。I don't know when he will come. (宾语从句,表示“他何时会来”,用将来时)I will call you when he comes. (时间状语从句,表示“当他来的时候”,用一般现在时)3. until 的用法肯定句:主句(延续性动词) + until... “直到……为止”He waited until the rain stopped.否定句:主句(not + 瞬间动词) + until... “直到……才……”He didn't leave until the rain stopped. (直到雨停了他才离开。)1.—Have you ever visited the West Lake —Yes.
