为什么Could you tell me what's wrong with you ?中从句没用陈述语序?
还有在Could you tell me what's the matter with you?Cocld you tell me what's the date of your return?中都不是用的陈述语序?

What's wrong with you?这一句是口语,表示“你怎么了?”.从句型结构上讲,what疑问词是主语,is是系动词,wrong是形容词,作表语.句子本身就是疑问词引导的陈述句序,所以没有必要更改.
再比如:Could you tell me who is the man over there?也是同样的句型结构,所以关键是看疑问词在疑问句中做主语还是其他成分.如果做主语,句序不需要改变;如果做宾语或者补语等其他成分,则需要改为陈述句序.
