题目内容：

I haven't heard from Henry for a long time.-What do you suppose----to him?
A.was happenning
B.to happen
C.has happend
D.had happend
还有为什么不选B而选C不是也有suppose to do的吗

优质解答

没有,suppose to do,是be supposed to do 应该做什么事这里其实是：I suppose what has happened to him,是宾语从句,意思是：我猜 他发生了什么事,特殊疑问句,将特殊疑问词提前到句首变成了题目 What do you suppose...
