2. “……就……”英语表达法

(1) as soon as 归纳：

as soon as 引出的时间状语从句既可以放在主句之前，也可放在主句之后，表示它所指的动作发生在另一分句所指的动作之前。

as soon as 可以与动词的一般现在时，一般过去时或完成时态连用，主句的动词使用相应的动词现在时，过去时或将来时。He started as soon as he received the news.

他一得到消息就出发了。As soon as he had got into the car, I said "good morning" to him in French and he replied in the same language. 他一上车，我就用法语向他道了声早安，他也用法语作了回答。

(2) hardly / scarcely / barely...when / before...no sooner... than...归纳：

注意搭配关系：hardly / scarcely / barely和no sooner不可以放在when / before和than之后。hardly / scarcely / barely和no sooner否定词位于句首时，句中的主语和谓语必须部分倒装。hardly / scarcely / barely和no sooner引导的是主句，表示它的动作发生在从句之前，故常用过去完成时；而when / before和than引导的从句只能与一般过去时连用。该句型含惊奇之意。Mrs Winthrop had no sooner left the room than they began to gossip about her.温思罗太太刚离开房间，他们就议论起她来了。Scarcely / Hardly / Barely had he begun to speak when I sensed that he was in trouble. 他刚一开口，我就感到他遇到麻烦事了。No sooner had we set out than a thunderstorm broke.我们一动身就遇上了大雷雨。

(3) the moment / the instant 归纳：名词短语the moment / instant / minute / second 和副词immediately / directly 可以用做连词，相当于as soon as，引导的是时间状语从句；从句既可放在句首，也可放在句中。 The moment I saw him, I knew that there was no hope. 一见到他，我就知道没希望了。The instant you leave this tent, you will get a big surprise. 你一出帐篷，便会大吃一惊。We will leave the minute you're ready. 你一准备好，我们就走。She returned immediately she heard the bad news. 她一听到这个坏消息，就返了回来。I left directly the clock struck twelve. 钟一敲十二点我就离开了。

(4) on + 动名词 (或表示动作的名词)归纳：动名词(或名词)结构表示它所表达的动作刚一发生或完成，句子谓语所表示的动作就接着发生。它相当于as soon as 引导的时间状语从句。On arriving in England, they were taken to the Crystal Palace by train. 他们一到英国便乘火车去水晶宫。He was greeted by the Prime Minister on his arrival at the airport. 他一到机场，便受到总理的欢迎。　　

另外，each time，every time 如同上面四种类型一样，可直接用作从属连词，引导状语从句。Every time I listen to his advice, I get into trouble. 我每次听了他的劝告，都会遇到麻烦。I'll think of my hometown each time I listen to that song. 我每次听这首歌，都会想起家乡。
