Question

I didn't hear_____because there was so much noise there.

A.what he has said B.what did he say C.what he said D.what had he said.
我还找到了一题类似的（见图片），这题的答案选Boy。请大神，帮我解释一下第一题选择什么，还有

做这两题要注意什么。

Answer 1

A.what he has said
因为didn’t hear 后是一个宾语从句,必须用陈述语序,只有C和A是陈述语序,又因“他所说的”在“didn't hear”之前发生，故要用过去完成时态，而C时态不对，所以选A了.

Answer 2

C.what he said
