what ___ Mary and Kate talking?A.about B.is C.is D.do
为什么不选about?

what is mary and kate talking about?为什么不选about你这句话完整的应该是 what is mary and kate talking about?意思“mary和kate在谈什么呢”这是在没有上下文的情况下的最正确的事情但如果你给出的what ___ mary and kate talking? 这句是没问题的,那么就要选 about 了,意思就变成了“ 那mary 和kate说话这件事怎么办?”这个就需要接上下文理解了
