江苏省2014届高三语法专题复习-状语从句.doc

江苏省 2014 届高三语法专项- 状语从句(1) 【考点分析】状语从句是每年高考必考的内容,在高考试题中加上其它从句的干扰,以及倒装句,强调句的介入,使得状语从句更为复杂。 1. 时间状语从句由下列连词引导: when, while, as, before, after, once, till, until, since, as soon as, now that, hardly … when, scarcely … when, no sooner … than, 有一些表示时间的副词(短语)或名词短语也可引导时间状语从句。如: directly, instantly, immediately, by the time , the moment, the second, the minute, the instant, every time, each time, next time, the last time 等重点内容如下: ① when, while, as 引导的时间状语从句▲ as 表示“当……的时候”,往往和 when/ while 通用,但它着重强调主句与从句的动作或事情同时或几乎同时发生。 She came up asI was cooking. ( 同时) The runners started as the gun went off. ( 几乎同时) ▲ when(at or during the time that ) 既可以表示在某一点的时候,又可表示在某一段时间内,主句与从句的动作或事情可以同时发生也可以先后发生。 It was raining when we arrived. ( 指时间点) When we were at school, we went to the library every day. ( 在一段时间内) When we arrived there, the film had already begun. ( 先后发生) ▲ while 意思是“当……的时候”或“在某一段时间里”。主句中的动作或事情在从句中的动作或事情的进展过程中发生,从句中的动词一般要用延续性动词。在 when 表示 a period of time 时,两者可以互换。 Please don ’t talk so loud while/when others are working. He fell asleep while/when reading. Strike while the iron is hot.( 不可用 as或 when ,这里的 while 意思是“趁……”) ② before 状语从句的重点句型▲……之后……才: It was a long time before I got to sleep . ▲不多久……就: It wasn ’t long before he told me about the affair. ▲不等……就: Before I could get ina word, he had measured me. ▲刚……就: He hardly entered the room before he heard the telephone ring. ▲先……再: You can have a few days to think about it before you make your decision. ③ since 引导的从句用延续性动词的过去式( 包括过去完成时), 则从句的动作已经结束, 从句意思是否定的。如果从句的动词是延续性的用完成时态, 从句意思是肯定的。▲ He has never been to see me since I was ill. 我病愈后,他一直未来看我。(不在生病了) ▲ He has never been to see me since I have been ill. 我病了,他一直未来看我。▲I haven ’t heard from him since he lived here. 自从他这里搬走,我就没有收到他的信。(不住在这儿了) ▲I know him very well since he has lived here near us. 自他住在我们附近以来,我对他很了解。▲ It’s three years since I was in the army. 我退伍已三年了。(不在服役了) ▲ It’s three years since I have been in the army=It's three years since he joined the army. 我入伍已三年了。④如果与 till 与 unti
