10、的人称、时态、指示代词、时间状语和地点状语等一般均要作相应的变化。一、如何变人称：一、如何变人称：“一随主，二随宾，第三人称不更新一随主，二随宾，第三人称不更新”。“第三人称不更新第三人称不更新”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。e.g.Mr.Smith said:Jack is a good worker.Mr.Smith said Jack was a good worker.“二随宾二随宾”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，或被第二人称所修饰。从句中的人称要跟引号外的主句的宾语一致。如果引号外

11、的主句没有宾语。也可以用第一人称。e.g.He said to Kate,How is your sister now?He asked Kate how her sister was then。“一随主一随主”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。e.g.She said.My brother wants to go with me.She said her brother wanted to go with her.二、如何变时态：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

12、态；过去时态改为完成时；过去完成时则保留原来的时态。e.g.She said,I have lost a pen.She said she had lost a pen.She said,We hope so.She said they hoped so.She said,He will go to see his friend.She said he would go to see his friend.（1）一般现在时变为一般过去时（2）现在进行时变为过去进行时（3）一般将来时变为过去将来时（4）现在完成时变为过去完成时（5）一般过去时变为过去完成时（6）过去完成时不变，仍为过去完成时时态

13、变化规律时态变化规律三、如何变状语：三、如何变状语：直接引语变间接引语，状语变化有其内在规则，时间状语由“现在”改为“原来”（例：now变为then,yesterday变为 the day before）地点状语，尤其表示方向性的，或用指示代词修饰的状语，由“此”改为“彼”（例：this 改为that)。e.g.He said,These books are mine.He said those books were his.指示代词、时间状语、地点状语和动词的变化指示代词、时间状语、地点状语和动词的变化：指示代词：this that these those 表示时间的词：now then t

15、is mother said to me,“Mr Harry is in charge of the work.”His mother told me that Mr Harry was in charge of the work.直接引语是一般疑问句，间接引语用 whether/if 引导，疑问语序变为陈述语序，谓语动词 say(said)改为 ask(asked)。e.g.Mr Tonny said to me,“Are your injuries severe?”Mr Tonny asked me if/whether my injuries were severe.直接引语是特殊疑问句

16、，间接引语用原来的疑问词引导，疑问语序变为陈述语序。e.g.Mary asked me,“When did the British prince become infected with the disease?”Mary asked me when the British prince became infected with the disease.直接引语是祈使句，间接引语变为 ask/tell/order sb.(not)to do sth.句式。e.g.He said,“Dont subscribe to her view.”He told me not to subscribe t

17、o her view.【注意注意】祈使句中的 please 在间接引语中必须省略。e.g.“Please pass me the pump,”he said to her.He asked her to pass him the pump.直接引语是客观事实、真理、规律等，变成间接引语时，时态不变。e.g.The teacher told his students,“The earth goes round the sun.”The teacher told his students that the earth goes round the sun.目标二：目标二：To convert so
