Have you finished your homework?Yes,i(_)it just now.

问题描述:

Have you finished your homework?Yes,i(_)it just now.
A(FINISH)
B(HAVE FINISHED)
C(FINISHED)
D(WILLFINISH)

首先排除A和D.
那么B和C应该选哪一个呢?
B是 have finished.
表示已经完成.是现在完成式.
如果要用B.后面就不能加just now.
just now表示刚才.
那么时态就对不上了.一个表过去,一个表现在.
因此对于"刚才"这个时态
要用finished.过去时.
因此选C./
