宾语从句疑问句I asked what was wrong with him.为什么不用陈述句顺序?还有类似这类的不用陈

这里what充当宾语从句的主语,所以what is本身就是主+谓的正常语序,不需要倒装.
(1).Bill wanted to know who did this.
(2).I don't know what's the matter with Bob?
(3).I don't know what's wrong with them?
记住这个原则
在作为宾语从句时,始终保证主语+谓语的陈述顺序
看这个例子
例如
Could you tell me where you are from?(where作from的宾语,整个from where作宾语从句中的表语) (或者说Could you tell me from where you are?总之保证主语+谓语这1陈述顺序,即you are而不是are you)
