  全部:新概念英语第二册第38课知识点解析(汇总)

  as soon as只有一种用法,就是一...就...简单讲,这个副词短语并没有固定的时态要求,一切按照句意确定就可以了。

  该句型可以说是所有表“一...就...”的句型中最为常见而简单的。它既可以用来描述当前的状况或动作,也可以用在过去的时间背景下。如:

  As soon as he comes, we will set out for Shanghai. (他一来我们就动身去上海。)

  I gave the alarm as soon as I saw the smoke. (我一看见冒烟,就发出了警报。)

  【注意】

  as soon as常和possible一起构成固定表达as soon as possible,表示尽可能快地。如:

  We must get to the airport as soon as possible. (我们必须尽快赶到机场。)

  as soon as的时态用法非常灵活,现在时时主句用将来时,从句用一般现在时或完成时。

  As soon as I finish my homework, I will go and play with you.

  As soon as I have read this book, I will return it to you.

  在过去式的情况下,如果从句用过去式,主句用过去式也可以。比如上面的例句。

  as soon as一…就…它的意思相当于:

  directly

  immediately

  instantly…

  = the second

  the minute

  the moment

  the instant…

  下面我们通过几个例句来看看详细的用法

  He came around to see me as soon as / the moment/ immediately he checked in the hotel.

  他刚一入住宾馆就来看我.

  They informed us the news immediately / directly they got it.

  他们一得到消息就通知了我们.

  The policeman came to the spot the moment / the instant / the minute she heard of the accident.

  一听说事故,这位警察就到了现场.
