问题补充：

We don’t know , maybe in the afternoon.

A. why will we start

B. how we will start it

C. when we will start

D. where we will go

答案：

A. why will we start

B. how we will start it

(答案→)C. when we will start

D. where we will go

解析：试题分析:句意:我们不知道我们什么时候开始的，可能是在下午。这里宾语从句，其语序应该是陈述语序，故排除A；根据maybe in the afternoon这里叙述的是时间，所以应该用when。
