一、如何变人称：
学生在将直接引语变间接引语时。常常弄不清人称变化。下面有一句顺口溜“一随主。二随宾，第三人称不更新”。“一随主”是指在直接引语变间接引语时，如果从句中的主语是第一人称或被第一人称所修饰。从句中的人称要按照主句中主语的人称变化如：
She said. 'My brother wants to go with me. '→She said her brother wanted to go with her.

“二随宾”是指直接引语变间接引语时，若从句中的主语及宾语是第二人称。或被第二人你所修饰。从句中的人称要跟引号外的主句的宾语一致。如果引号外的主句没有宾语。也可以用第一人称，如：
He said to Kate. 'How is your sister now?'→He asked Kate how her sister was then。

“第三人称不更新”是指直接引语变间接引语时。如果从句中的主语及宾语是第三人称或被第三人称所修饰从句中的人称一般不需要变化如：
Mr Smith said。 'Jack is a good worker。'→Mr Smith said Jack was a good worker。

二、如何变时态：
直接引语在改为间接引语时、时态需要做相应的调整。
现在时它需改为过去时态；过去时态改为完成时；过去完成时则保留原来的时态。如：
1)She said. 'I have lost a pen.'→She said she had lost a pen
2)She said. 'We hope so.'→She said they hoped so.
3) She said. 'He will go to see his friend。'→She said he would go to see his friend。
但要注意在以下几种情况下。在直接引语变为间接引语时，时态一般不变化。

①直接引语是客观真理。
'The earth moves around the sun and the moon moves around the earth, the teacher told me. → The teacher told me the earth moves around the sun and the moon moves around the earth。
