题目

The building project ____quickly over the months after it was decided at the meeting.
A.had developed B.has developed C.would develop D.developed
我想知道为什么B不可以，时间状语over the months 不应该用完成时态吗？

答案

这个考查时态.
题意：这项建筑工程在会议决定后的几个月内进展得很快.这里的时间关键词是over the months"过了几个月",是指会议过后的几个月,所以还是过去的,而没有说到现在为止,所以选D.注意区别的是,如果用over the past (few) months“在过去的几个月”,则是强调到现在为止,或者对现在的影响,那么此时才用现在完成时,即B选项.
不懂可以继续问,
