—Why_________ there so many students sitting crowding on the playground?

—There is going to ________a football match there.

A. is; are B. are; have C. are; be D. have; have

C

句意：——为什么在操场上有那么多学生坐在那里？——那里将举办一场足球比赛。

根据there be有，have/has有，这里是there be结构，所以不能用have/has，排除B/D；根据is用于单三和不可数名词，are用于第二人称和复数，many students复数，所以第一个空用are，根据be going to后接动词原形，所以第二个空用be；故选C。
