There must have been something wrong with him,

题目

There must have been something wrong with him,
A mustn't there B isn't there C was there D wasn't there
应该选择哪一个?
haven't there对吗.

答案

haven't there.对现在情况的推测,问句部分用主动词（do,be)一般现在时的适当形式.若是现在进行时,问句部分用现在进行时的适当形式表示.若是there be结构,问句用isn't/aren't there.如：1)He must be there,isn't he?...
