请问如何区分下列英语的宾语从句?我觉得都对啊……〔正确：the doctor asked me w

The doctor asked me,"What's the trouble with you?" 这是直接引语的句子.变成间接引语就成了：The doctor asked me what was the trouble with me.原来的问号,要变成句号.因为宾语
从句是陈述句.
The teacher asked me,"Have you finished your homework?"
间接引语：The teacher asked me if I had finished my homework.
The doctor asked me "When did you have your dinner?"
间接引语：The doctor asked me When I had had my dinner.
.what不能看做是宾语么？我觉得也可讲得通啊……当然可以呀。For example:He asked me,"What did you do yesterday?"间接引语: He asked me what I had done the day before.呀呀呀怎么老回答不到点上啊亲!这么说吧，为什么what's the trouble with you在间接直接引语语序都未改变？还有what's the matter也是。难道这是个例外要特殊记忆么？对不起，回答问题时，大意了：直接引语：He asked, “What is the trouble with you?”间接引语：He asked what the trouble was with me.直接引语：He asked, "What is the matter with you?"间接引语:He asked what the matter was with me.直接引语：He asked,"what do you want?"间接引语：He asked what I wanted.间接引语变成了陈述句，句尾应使用句号。Any other questions？I'm always at your service.What does that mean in English?
