Tell me what is wrong with it?还是Tell me what the matter is with it?为什么?

第一句对的.第二句不对.
what是句子主语,所以不用改的
What is wrong with it?
What is the matter with it?
这两个句子中,what是主语+系动词+表语……
the matter可以看成形容词的.
如Is there anything wrong with you?
=Is there anything the matter with you?那么在宾语从句中，有哪些句型不用变成陈述句语序呢？（简单说说就行，我知道句型太多不可能都讲到）比如说what引导的疑问句？引导词做主语就不用改的。如Do you know who will come?I found what had happened to him.The teacher told me which book belonged to me.(which book 是从句主语）这种结构在主语从句，表语从句中也是如此。也包括特殊疑问句的。Who will come to help me?
