—Do you know ?
—Next month.
A. When will they come
B. when did they come
C. When they came
D. when they will come

A. When will they comeB. when did they comeC. When they came(答案→)D. when they will come解析：根据题干，我们可知本句是一个宾语从句或间接引语。宾语从句或间接引语的语序应该用陈述句语序，所谓陈述句语序，就是谓语动词（包括be动词，助动词和情态动词）应放在主语之后。通过观察，排除AB；根据next mouth可知，应该用将来时。所以本题选D。
