问题补充:
- Have you known each other for long?
- Not really. we started to work in this school.
A. Just after
B. Just when
C. Ever since
D. Just before
答案:
A. Just after
B. Just when
(答案→)C. Ever since
D. Just before
解析:考查连词:A. Just after就在…后面,B. Just when就在…时候,C. Ever since自从,D. Just before就在…前面,句意:--你们认得彼此很长时间了吗?--不是,(我们认得)是自从在这个学校学习以来。这句话的主句We have known each other被省略了,所以从句用ever since(和现在完成时连用),选C。
