If引导条件状语从句的详细用法解答

高二必修五重点难点——时间、条件和让步状语从句
Section ⅡGrammar 时间、条件和让步状语从句 时间、条件和让步状语从句在高考中约占3分，考查形式主要有单选、完型填空、语篇填空和改错，主要考察这三种从句中的引导词、谓语动词。 幻灯片3 一、时间状语从句 1．no sooner...than与hardly...when 都表示主句与从句的动作相继发生，意为“一……就……，刚刚……就”，主句动词用过去完成时。如no sooner，hardly位于句首时，主句用倒装形式。 He had hardly gone to bed when the doorbell rang. ＝Hardly had he gone to bed when the doorbell rang. 他刚睡下门铃就响了。 No sooner had he got off the train than his daughter ran towards him. 他刚下火车，他女儿就向他跑了过来。 幻灯片4 2．as soon as，the moment，immediately 引导的从句表示从句动作一发生，主句动作随即发生，常译为“一……就”。名词词组the second，the minute，the moment，every time，any time，next time，the first/last time，the day/week/month等亦可作连词，引导时间状语从句。 They told me about it as soon as/immediately/the moment they got the message.他们一听到口信就把消息告诉了我。 Every time he walked by the lake，he thought of his childhood life.每当他走过那个湖时，就会想起童年的生活。 注意：immediately可用做连词也可用做副词。 幻灯片5 3．till和until 词义是“直到……，一直……为止”，表示一个动作持续到某一时刻或某一动作发生为止，在句首只能用until。在肯定句中，主句中要用延续性动词；在否定句中，可以用非延续性动词。 She stood there till/until he had passed out of sight. 她站在那里看着，直到望不见他的身影。 Until they had finished the work，they did not go home. ＝Not until they had finished the work did they go home. 直到工作完成了他们才回家。 幻灯片6 注意：(1)在not...until结构中not until位于句首时主句部分倒装。在强调句中，强调until引导时间状语时，常把not提前，构成It isn’t/wasn’t until...that...。(2)not...until和not...before意思相同，表示“直到……才，在……以前不”。 幻灯片7
