题目

they ____ an english evening next sunday.请说明为什么这么选的理由,
they ____ an english evening next sunday.
A.are having B.are going to have C.will having D.is going to have
请说明为什么这么选的理由,

答案

选B.
分析：句意为“他们下周日将有一个英语之夜.”时态要用将来时,即will have/be going to have.因为给出了肯定时间（next Sunday）,所以使用be going to have.'they' 是复数,be动词为are.
