Over forty years has passed since the first bridge was built in the district.
问题描述：
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
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
