I don't know what is wrong with you为何从句不用陈述语态？

what's wrong with you ?这一句的主语就是what，因此就是一个陈述句形式，比如：what happened to you yesterday?此时的what也是做主语，类似的还有：who went to the theatre yesterday? 手工翻译，尊重劳动，欢迎提问，感谢采纳！

Do you know what's wrong with him?中 what's wrong with him为什么不用陈述语序？

what's wrong with him就是陈述语序，

what 是主语，

is 是系动词

wrong是表语

what is wrong with you在宾语从句中为什么不用陈述语序

what's wrong 里的what 是做主语，所以它的顺序自然是正常语序。

以Do you know开始的句型为何后边有陈述与疑问两种，如何区分？多谢！

Do you know开始的句型后边跟的应该是宾语从句，而宾语从句则来源于陈述句或者疑问句，但是，不管来源如何，一律采用陈述语序。
