同学你好~
1.用短语连词as soon as来表示“一……就……”是最为常见的，并且有时可以改为so soon as，意思一样。例如：
They quarelled as soon as the wedding ceremony ended.
婚礼一结束他们就吵起来。
So soon as there is any talk of paying, his enthusiasm cools down.
一谈到付款的事，他就不热心了。

2．用连词when、whenever和once也可以表达“一……就……”。
I hid myself when I saw him coming.
我一看见他过来，便躲藏起来了。
I’ll visit him whenever I get the chance.
我一有机会就会去看望他。
Once the film is made, all young people will want to see it.
这个影片一拍好，所有的年轻人都会想看的。

3．用连词no sooner …than…、hardly/scarcely/barely…when…，同样可以表达“一……就……”。例如：
No sooner had they got to the plant than they started to work.
他们一到工厂就开始工作了。
Hardly had I arrived when I had a new problem to cope with.
我一到达就有新问题需要处理。
Scarcely had the clown appeared when the spectators roared with laughter.
小丑刚一出场，观众就哄堂大笑。
Barely had he arrived when he had to leave again.
他刚到就又得走了。

4．可用副词immediately、instantly和  directly来表达“一……就……”。这时，这几个词所起的作用相当于连词，引导时间状语从句。这种用法主要用在英国英语及口语中。
Immediately he arrived, he started telling us what to do.
他一到达，就开始告诉我们该做什么。
I came directly I got your message.
我一得到你的口信就立刻来了。

5．在名词minute、moment和instant前加上定冠词the也可以引导时间状语从句来表达“一……就……”。它们后面可以加that，含义不变。例如：
The moment (that) he spoke we recognized his voice.
他刚一讲话，我们就听出了他的声音。
I’ll tell him the minute (that) he gets here.
他一到这儿我马上就告诉你。
I sent you the news the instant (that) I heard it.
我一听到这个消息就传达给你了。

6．某些表示“立刻”含义的副词跟after连用可以表达“一……就……”。这里的after既可以作连词引导从句，也可以作介词后跟名词或动名词短语。可以这样用的副词有：immediately、instantly、soon、right等。例如：
The machine will start instantly after you press the button.
你一按电钮机器就会开动。
The turtle returns to the sea soon after it has laid its eggs.
海龟一产完卵就返回大海。
I would like to propose that for sixty to ninety minutes each evening, right after the early evening news, all television broadcasting in the United States be prohibited by law.
我想建议每天晚上一播完晚间新闻，美国所有的电视节目都依法停播六十至九十分钟。
We had a meeting to sum up our experiences immediately after finishing the work.
工作一结束，我们立即开会总结经验。

7．某些at引导的介词短语可用来表达“一……就……”，如：at the sight of（一看到）；at the thought of（一想到）；at the sound of（一听到）；at the first opportunity/chance（一有机会）等。
After being turned down several times, the young man felt discouraged at the thought of looking any further for jobs.
在几次被拒绝之后，那年轻人一想到再去找工作就无比沮丧。
The birds scattered at the sound of the gun.
那些鸟一听到枪响就四处飞散。
At the sight of the police officer the thief ran off.
一看见警官，小偷就逃掉了。
I’d like to pay a visit to you at the first opportunity.
我愿一有机会就去拜访您。

8．一些表示短暂性动作的动词，如：arrive、return、reach、hear、see、receive、enter、step、get、recognize、leave等，它们相应的名词形式或动名词形式用在upon或on之后可表达“一……就……”。例如：
Upon/on his return from Japan, Prof. Li went directly to his laboratory and started working with his colleagues.
李教授刚一从日本回来就到他的实验室，开始和他的同事们一道工作起来。
Upon/on arriving at the spot, he found that the gypsies had gone.
他一到现场，就发现吉普赛人已经走了。
