Question

There________a class meeting this afternoon.

A.is going to have B.is going to be C.will have D.is going to has

Answer

B

【解析】

句意：今天下午有一个班会。

考查there be 结构。is going to have不是there be 结构；is going to be是there be 结构；will have不是there be 结构；is going to has不是there be结构，用法错误。这道题考查的是there be 句型的用法。根据原句中的this afternoon,判定原句为一般将来时，there be句型的一般将来时构成是 There is/are going to be ... / There will be...结合句意可知，此空应填is going to be，故选B。
