in是不是用现在完成时
问题描述：
in是不是用现在完成时
In the past few years _______ great changes in Shanghai.
A.there have been
B.there have
C.there were
D.there will be
我选的是C可答案A,domo!
答
这是道初中长考题,技巧：_____great changes in shanghai(in the past few years)都选择现在完成时态,这里原句是there is a great change in XXX ,变化一般都是可持续的动作,指上海不停的在发生变化,所以用现在完成时恰当!
