高考英语_状语从句_详解习题加答案

2. 时间状语从句起时间状语作用的句子；可放在句首，句中和句尾常用引导词：when，while, as, after, before, since, till, until, the moment, hardly … when , no sooner … thanwhen, while, as的用法1) when 用法最广，常可代替while和as, 在while 引导的从句中，动词只能是延续性的When the fire broke out, all the students were sleeping soundly.The telephone rang while I was taking a bath.2) 当两个表示时间延续的动作同时发生而又有对比意味的时候，用while，在这样的复合句中，主句从句的时态通常是相同的。
Father was preparing a report while I was playing PC games.3) 常用as的情况：一边…一边；表示随着短暂动作的发生，另一行为伴随发生As he talked on, he got more and more excited.They talked as they walked along the river.My cap was blown away as I sat down.until和till的用法表示“一直到…”时，主句和从句都用肯定式；I will wait until/ till the concert is over.表示“直到…才…”是，主句用否定，从句用肯定式。
They can’t go until Sunday.since的用法He has written to me frequently since he was ill. 自从他病好以来，他常写信给我。
