Question

It is fairly common in Africa for _____ a group of musicians surrounded by others who also join in the performance.

A．there are

B．there being

C．there to be

D．there be

Answer 1

C

试题分析：考查不定式做主语的用法，句型是：It’s +adj.+for sb to do。这里用的是there be句型，所以选there to be。句意是：在非洲有一群音乐家被别人包围着，这群人也同样参加了表演这是相当普遍的。选C。
