1、Both his parents look sad . Maybe they ______what's happened to him .

解析:现在完成时主要强调过去发生的动作对现在造成的影响,或过去发生的动作还未结束,一直持续到现在或将来,重点在于对现在的影响。这种考查难度较大,往往无时间状语,需要从上下文分析、推理才行。

故上两侧根据上下文分析、推理,正确答案是B。

2. Kate's never seen Chinese films, ____ ?  

A. hasn't she       B. has she       C. isn't she       D. is she

解析:陈述句部分含否定词never,简略问句部分要用肯定式,又因Kate's是Kate has的缩写,故选B。 

3. He has _______ been to Shanghai , has he ?

A.already      B.never      C.ever      D. still

解析:现在完成时常与already(已经)just(刚刚,正好) 、ever(曾经)、never(从来,也不;从不)、before(以前 )、yet(仍然)等连用。故应选B
