直接引语变间接引语的人称变化倒不是中国学生的难点，但是对于时态的变化却使很多学生一筹莫展。这篇文章里给大家解决这一问题。
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。
②直接引语是过去进行时，时态不变。如：
Jack said. 'John, where were you going when I met you in the street?'→Jack asked John where he was going when he met him in the street。
③直接引语中有具体的过去某年、某月、某日作状语，变为间接引语时，时态不变。如：
Xiao Wang said. 'I was born on April 2l, 1980。' →Xiao Wang said he was born on April 20, 1980。
④直接引语如果是一般现在时。表示一种反复出现或习惯
