问题描述：
a result of the serious flood,two-thirds of the buildings in the area____.
As a result of the serious flood,two-thirds of the buildings in the area____.
A.need repairing B.needs to repair C.needs repairing D.need to repair
为什么呢?
答
由于后半句的主语是two-thirds of the buildings,因此谓语不能用单三形式,排除BC
而如果用D的形式,则应是 need to be repaired
因此只能选A
表物的主语后加need doing可以理解为是固定用法,表主语需要“被”如何
