Question

she didn't know _ A.where would they have the meeting B.why they will have the meeting

C.what to have the meeting
D.when to have the meeting

Answer 1

正确的答案应该是 A. B 和C 是语法有瑕疵。D 在逻辑上有问题；She didn't know when to have the meeting 表明她是会议组织者，所以她不知会议何时进行是讲不通的。

【英语牛人团】

Answer 2

选D, 因为know后面加宾语从句排除A，C项意思不通，B项主从句时态不一致

Answer 3

选B应该是正确的
