这个是试卷上的题目，全错的可能性不大吧？

我很负责任地来说说正确的答案.这五句都是考的同一知识点,即：“一.就”
1.(On/Upon）the teacher's arriving,we started the meeting.
本句的要点在于on/upon+n./doing形式,表示“一...就”如:
On/Upon his stepping out of the taxi,he was seized by two men.
一下出租车,他就被两个人抓住了.
2.(Immediately/Directly/Instantly)the class teacher arrived,we started the meeting.
本句的要点在于immediately/directly/instantly+从句,表示“一...就”
3.(The )(moment/time/minute/instant/second)the class teacher arrived,we started the meeting.
本句的要点在于the moment/time/minute/instant/second+从句,表示“一...就”
4.(Hardly/scarcely/barely)had the teacher arrived(when)we started the meeting.
本句的要点在于hardly/scarcely/barely.when...表示“一...就”
本句是一个倒装句,正常的语序应该是
The teacher had hardly/scarcely/barely arrived when we started the meeting.
因为hardly/scarcely/barely都是否定词放句首,句子要倒装,就成为楼主的题目那样的形式.而且这个句式还要注意时态的搭配,主句用过去完成而从句用一般过去式,如:
I had hardly left the room when the bell rang.
=Hardly had I left the room when the bell rang.
5.(No)(sooner)had the teacher arrived(than)we started the meeting.
本句的要点在于no sooner...than...表示“一...就”
本句也是一个倒装句,正常的语序应该是
The teacher had no sooner arrived than we started the meeting.
同上题一样,因为no sooner是表否定的词,放句首,句子要倒装,就成为楼主的题目那样的形式.而且这个句式也要注意时态的搭配,主句用过去完成而从句用一般过去式,如:
I had no sooner left the room than the bell rang.
=No sooner had I left the room than the bell rang.
