答案是C.在What is the matter with.句子中,疑问词what做主语,其疑问语序和陈述语序是一样的,也就是说,它作宾语从句时,不需要做语序的变化.类似的问句还有：What is wrong with .

C

C
此句是宾语从句（这个知道吧？）后面引导的句子必须倒装成这种形式：疑问词+谓语（be动词、助动词等）+宾语 也就是陈述句形式
但是what's the matter 和what is wrong 特殊，它们的疑问词都是句子中的主语，故不用倒装

C
宾语从句的两个重要特点:陈述句词序,前后时态一致.
选项A B D都是一般疑问词序.
祝你进步!

答案C
分析：本题主要是考察宾语从句的用法。首先一般情况下，宾语从句都要用陈述句语序。但本题的C选项是一个特例，what's the matter是一个固定用法，在宾语从句中不用变语序。所以答案选C
