窗体顶端直接引用别人原话，叫直接引语。用自己的话转述别人的话，叫间接引语。间接引语常用宾语从句表达。直接引语前后要用引号，间接引语不用引号。
He Said: I have seen the film. 他说： 我已经看过这部电影。 (直接引语)
He said that he had seen the film. 他说他已经看过这部电影了。(间接引语)
怎样把直接引语改为间接引语?
1.根据意思改变人称。
如：They said, We are busy now. (直接引语)
They said that they were busy then. (间接引语)
一般来说第三人称代词常常不变，第一人称一般变为第二人称。
2.若主句的谓语是过去时态，直接引语改为间接引语时，要调整时态。
直接引语 间接引语
现在时 过去时
过去时 过去完成时(少数不变)
现在完成时 过去完成时
现在进行时 过去进行时
一般将来时 过去将来时
过去完成时 不变
现在完成进行时 过去完成进行时
由上述内容可知，时态的变化都是由现在的某个时态而变成了达去的某个时态。要特别注意，客观真理以及过去完成时在改为间接引语时，不需作时态调整。
3.指示代词，进间状语也要作调整。
直接引语 间接引语
this that
these those
now then
today that day
tonight that night
tomorrow the next (following) day(month, year)
yesterday the day before
yesterday afternoon the afternoon before
last year (month) the year (month) before
ago before
here there
注：动词(come)也常变为go
4.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.
