初中英语选择题..Do you know___?……

选A.
这是一句宾语从句，从句要保持陈述句语序。但问题是，What's the matter with him? 的主语就是What,the matter with him 是表语。 所以该问句的语序和陈述句语序一致。不用再调整。
举例说明：
He's my father.陈述句
Who's my father? 疑问句，疑问词作主语，所以仍属陈述句语序。
Do you know who's my father?
Who's he? 主语为he
Do you know who he is?

总结：
what's the matter with... , what's wrong with..., which is the way to... 等都属系表结构，疑问词就是主语，作宾语从句时，都不必调整语序。

Do you know___？

B.what the matter with him is
Do you know是宾语从句的标志之一，而宾语从句的从句部分用陈述句语序（主谓结构），故选B。

A.并不是陈述句语序。what's the matter with him 这句话中the matter with him 才是主语！主语放到句末了，怎么还能是陈述句？！

选B

Do you know 后面接从句
从句要用陈述句语序

A显然是疑问句
所以选B

A 从题中可知选项要做know的宾语从句 而在宾语从句中要用陈述句语序 A就是陈述句语序 what是主语 is 是宾语 the matter是表语

选B....
因为后面该填陈述句...
What's什么的不能在这里用`!
解释的不好...但是是选B~!
