5. 英语中有一些固定的省略结构 (1)在以if,when,though,as if(好像)等连词引导的状语从句中,如果主句主语和从句主语一致,且从句谓语中含有动词be,或者从句为it is结构时,从句往往使用省略的形式。 If(it is)necessary,we shall send a telegram home. 如有必要,我们就往家里打电报。 Whenever(it is)possible,he will come to my help. 他一有可能就来帮助我。 While(you are)cycling,dont forget the traffic lights. 骑车时,不要忘记看红绿灯。 (2)由固定词组引导的疑问句。 What about having a game of chess? 下盘棋怎么样? How come they left you alone here? 他们怎么会把你一人留在这里呢? What if its raining? 如果天下雨怎么办? Why not try again? 为什么不再试试呢? (3)在口语中,为了避免重复,不定式可以省去和句子前部重复的动词原形而只留下不定式符号to。 He may leave if he wishes to. 他可以走,如果他愿意的话。 Dont go till I tell you to. 等我叫你走你再走。 热点考向四 感叹句 感叹句常用的七大句型 (1)How+形容词/副词+主语+谓语!
