我想問reported speech 既野, 唔該

問題形式的reported speech ：
1. Peter asked the doctor, "Why should I stop smoking ?
應轉成
Peter asked the doctor why he should stop smoking.
因 why, what, who, when, How, ....之類的字在
reported speech 中的轉變是不用加 that , if, whether
的字。

2. 以下 question 形式 reported speech 要加 if 或
whether 亦要轉 tense.
原句 Mr. Chan asked Peter, " Do you want to have
some tea ?"
轉做 Mr. Chan asked Peter whether he wanted to have
some tea.

I think it is
Peter asked the doctor tat why he should stop smoking.
