Over forty years has passed since the first bridge was built in the district.

题目

Over forty years has passed since the first bridge was built in the district.
表示一段距离,时间、重量、金额方面的词做主语,相应谓语不是为单数么,譬如:It is $20.为何这里over forty years 用的是"have passed" insteand of "has passed"
我的英文写错了哦 是Over forty years have passed since the first bridge was built in the district.以此为准.

答案

因为这里是over forty years(超过40年),不是确切的一个时间..所以谓语动词用复数.
如果是it's forty years就用单数
