nonbody knows where he is now.what do you suppose___him?

题目

nonbody knows where he is now.what do you suppose___him?
A.to happen
B.was happening to
C.have happened to
D.has happened to
为什么呢?suppose has happened?不就有两个谓语了吗?

答案

题目没有出错
这个句子中的 do you suppose可以省略 翻译中中文就是“你觉得”
打个比方 有两句句子
1、你觉得他什么时候来?
2、他什么时候来?
都是问你意见,所以你觉得可以省略.
把这句话改成陈述语气
You suppose sth has happened to him.
就和 I think you are beautiful 差不多 不是两个谓语 是有主从关系的.
至于为什么用完成时 我想lz应该知道的吧
