“一……就”表达：
1. “on+名词或动名词”结构，相当于时间状语从句，强调时间的短促和动作的紧凑。
如：On arriving (或On arrival) I discovered they had gone.我一到达就发现他们已经离开了。
2.hardly…when，主句中的谓语动词用过去完成时，when引导的从句的谓语动词用一般过去时；当hardly置于句首时，要求部分倒装，即助动词提到主语前，如：We had hardly（或Hardly had we）sat down at the table, when the phone rang.我们刚在桌子旁坐下，电话铃就响了。
3. scarcely ... before，如：Scarcely had the bell rung before they went to the playground. 铃一响，他们就到操场上去了。
4. as soon as，如：As soon as she entered the room, she knew there was something wrong.她刚进屋就知道有点不对劲。
5. at+名词/动名词，如：At seeing her mother/ At the sight of her mother，the girl burst into tears.一见到母亲，那女孩就放声大哭起来。
6. the instant/the moment/the minute (that)，如： I will pay you back, I promise, the moment I get paid. 我保证一拿到薪水就还你钱。
7. immediately/instantly/directly，如：Immediately the discussion was finished，the meeting was over. 讨论一完毕，会就散了。I went home directly I had finished work.我一干完活就回家了。
8. right after，如：The workers went home for a rest right after completing their task.（工人们一完成任务，就回家休息了。）
9. lose no time，如：When the new manager was appointed, he lost no time in reorganizing the office.新经理刚被任命，就开始重新调整办公室。
10.“no sooner…than”和“scarcely…when”都意为“一……就”，与hardly…when的用法相同，如：No sooner had she heard the news than she cried.她一听到这个消息就哭了。Scarcely had the game started when it began to rain.比赛才开始就下起雨来。
