1. 基本转换规则
直接引语： He said, "I am happy."
间接引语： He said that he was happy.
解析： 时态从 am 变为 was，人称从 I 变为 he。
2. 时态变化（若主句为过去时，句子时态需后推一格）
- 一般现在时 → 一般过去时
She said, "I like apples." → She said that she liked apples.
- 现在进行时 → 过去进行时
He said, "I am reading." → He said that he was reading.
- 现在完成时 → 过去完成时
She said, "I have seen this movie." → She said that she had seen that movie.
- 一般过去时 → 过去完成时
He said, "I went home early." → He said that he had gone home early.
3. 代词和指示词的变化
- I → he/she（She said, "I love music." → She said that she loved music.）
- my → his/her（He said, "This is my book." → He said that was his book.）
- now → then（She said, "I am busy now." → She said that she was busy then.）
- today → that day（He said, "I met her today." → He said that he had met her that day.）
- yesterday → the day before（She said, "I left yesterday." → She said that she had left the day before.）
- tomorrow → the next day（He said, "I will call you tomorrow." → He said that he would call me the next day.）
4. 祈使句转换（用ask/tell + to do）
直接引语： She said, "Close the door."
间接引语： She told me to close the door.
直接引语： He said, "Don't be late."
间接引语： He told me not to be late.
5. 疑问句转换
一般疑问句（if/whether）
直接引语： She asked, "Do you like coffee?"
间接引语： She asked if I liked coffee.
特殊疑问句（疑问词不变）
直接引语： He asked, "Where do you live?"
间接引语： He asked where I lived.
总结：
- 时态后推一格（若主句为过去时）
- 代词、时间、地点随上下文变化
- 祈使句用 to do 形式
- 疑问句用 if/whether 或保持疑问词
