1、若直接引语为陈述句，改为间接引语时，用连词that引导(口语中常省略)，其它作相应的变化。
He said, "I've just got a letter from my sister."
He said he had just got a letter from his sister.
需要说明的是，若引号里是两句话，改为间接引语后，第二句前也要用that连接起来。
"He was here a few weeks ago, and he came again yesterday." she said.
She said that he had been there a few weeks before, and that he had come again the day before.
2、若直接引语为一般疑问句(原为倒装语序)，改为间接引语时要用陈述句的语序而且还要加连词if 或whether引出。注意whether后还可跟or或or nor ，但if 不能。Whether可用在介词后或带to的不定式前面，而if不能。但若宾语从句为否定句时，常用if而不用whether。
He asked, "Are you a teacher or a student?"
He asked me whether I was a teacher or a student.
注：如果主句中的谓语为said，改为间接引语时要用asked，无间接宾语，要适当加一个me，us，him等。如
3、若直接引语为特殊疑问句，间接引语就要使用疑问词引出，而且要用陈述句语序。
"What are you doing here?" the guard said to us.
The guard asked us what we were doing there.
4、当直接引语为祈使句时，间接引语要改为带复合宾语(宾语+宾语补足语)的句子，宾补用不定式表示。
即：ask (tell, order, beg, etc) someone (not) to do something。注意不要用said。
"Don't mention it again," the said to her husband.
She asked her husband not to mention it againUID303

直接引语改间接引语的注意事项：
1、直接引语如果表达的是客观真理，谚（习）语，变间接引语时时态不变。例如：
The teacher said, “Theearth goes round the sun.”
The teacher said that the earth goes round the sun.
My father said, “Practice makes perfect.”
My father said practice makes perfect.
2、直接引语中被引述的部分是反复出现的，习惯性的动作或说话时情况仍然存在的，变间接引语时，时态保持不变，例如：
The boy said to us, “I usually get up at six every day.”
The boy told us he usually gets up at six every day.
He said, “We are still students.”
He said they are still students.
3、直接引语如果有明确的表示过去的时间状语，时态不变。例如：
He said to me, “I was born in 1978.”
He told me that he was born in 1978.
The engineer said, “I was at college in 1967.”
The engineer said he was at college in 1967.
4、直接引语中凡有when，since，while 引导的从句，在变为间接引语时，只改变主句时态，从句的时态不变。例
如：
He said, “I have studied English since I was a boy.”
He said he had studied English since he was a boy.
She said, “I read the book while I was waiting for a bus.
She said she had read the book while she was waiting for a bus.
Mr. Green said to them, “Joe told me all about his story when he asked for a job.”
Mr. Green told them Joe had told him all about his story when he asked for a job.
5、如果直接引语中引述部分含有insist, suggest, demand等引导的虚拟宾语从句，变间接引语时，引语中的主从句时态都不变。例如：
He said, “We insisted that she start immediately.
He said they (had) insisted that she start immediately.
She said, “He demanded that the girl leave at once.”
She said he demanded that the girl leave at once.
另外，如果说话人转述自己的话，人称则可不变。例如：
I said to him, “I have finished it.”
I told him I had finished it.
