问题补充:
As a result of the serious flood, two-thirds of the buildings in the area .
A. need to repair
B. needs to repair
C. needs repairing
D. need repairing
答案:
A. need to repair
B. needs to repair
C. needs repairing
(答案→)D. need repairing
解析:由于后半句的two-thirds 接的名词the buildings作主语,the buildings是可数名词,因此谓语用复数,故排除BC选项。且need在这里作为特殊的及物动词,其后面的宾语用动名词的主动式表示被动或者用不定式的被动式:need doing=need to be done。句意:因为严重的洪水,这个地区三分之二的房子受到破坏需要进行修建。
