要根據說話人的語氣來確定用哪種引導詞.
當說話人用陳述語氣時,用that 引導.如：
He said,"I'm tired."就轉述成：He said (that) he was tired.或 He told me (that) he was tired.
當說話人用祈使語氣時,用 tell 或want 或ask 轉述.如：
Tom said to me ,"Don't take my bag away." 應當轉述成：Tom told me not to take his bag away.
當說話人用一般疑問語氣時,用if 或 whether 轉述.如：
Kathy asked Lily,"Do you like music?" 應當轉述成：Kathy asked Lily if /whether she liked music.
當說話人用特殊疑問語氣時,用說話人的疑問詞轉述.如：
Kathy asked him,"Where were you born?"應當轉述成：Kathy asked him where he was born.
在轉述時,有一點非常重要,就是：轉述中的內容一律使用陳述語序,不能用疑問語序.
還的其他一些需要作適當改變的內容,你可以通過多做練習掌握起來.
打這些內容很累.我只能說到這里了.
