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性的动作，变间接引语，时态不变。如：
He said, 'I get up at six every morning。' →He said he gets up at six every morning。
⑤如果直接引语中的情态动词没有过去时的形式（例：ought to， had better, used to)和已经是过去时的形式时，（例：could, should, would, might）不再变。如：
Peter said. 'You had better come have today。' →Peter said I had better go there that day。
