2.There's no light on in the dormitory , they must have gone to attend the concert being held on campus,________?
A.aren 't they B.mustn't they C.haven't they D.shouldn't they
求解题过程.
1 D,首先two-thirds of the buildings 中心词为buildings,所以谓语用复数,因而排除B,C其次“物体+need doing（主动表被动）或者物体+to be done二者都表被动所以选 D
2 C第二句话,they应该是大写吧,答案选 C.haven't they ,原因 must have done表一种猜测,这种类型的题与翻译疑问句结合比较麻烦,得具体分析说话人的语境,该句的这个答案表示过去某件事对现在造成的影响,所以用现在完成时.另一个语境如果表过去则用didn't they?
