问题补充：
There a dolphin show at the zoo tomorrow evening.
A. was
B. is going to have
C. will have
D. is going to be
答案：
A. was
B. is going to have
C. will have
(答案→)D. is going to be
解析：句意：这明天晚上将会有一个海豚表演在动物园。there be 结构的将来时，在there be中间加入be going to或will表达“将要有”如：There is going to be a meeting this afternoon.今下午有个会。There are going to be two films this evening.今晚将有两部电影。be动词用is或are根据后面的名词的单复数来确定。故选D
