E.g.: 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.E.g.: He said to Kate, “How is your sister now?”→He asked Kate how ________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.E.g.: Mr. Smith said, “Jack is a good worker.”→Mr. Smith said________ was a good worker.直接引语变为间接引语:时态变化:直接引语在改为间接引语时,时态需要做相应的调整.其基本法则和我们刚刚学过的宾语从句的时态变化一致,也就是说从句时态要和主句时态一致.如果从句是过去时,主句要向后退一个时态,变成一种过去时.1．She said. “I have lost a pen.” →She said ______________ a pen.2．She said. “We hope so.” →She said _______________ so.3．She said, “He will go to see his frien d.”→ She said he_________ go to see his friend.(一般将来→ 过去将来) 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.是客观真理.E.g.: “The earth moves around the sun and the moon moves around the earth”, the teacher told me.→ The teacher told me the earth _______________ the sun and the moon moves around the earth.②直接引语是过去进行时,时态不变.Eg: 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.Eg: Xiao Wang said,“I was born on April 20, 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.Eg: He said, “I get up at six every morning.” →He said he __gets____ __up___ at six every morning.[即时练习]将下列句子连接成宾语从句.1．Light travels faster than sound．My teacher told me.My teacher told me ___________ light _____________ faster than sound.2．There will be a meeting in five days. Jack didn’t know.Jack didn’t know ________ there ________ _______ a meeting in five days.3．Can they speak French? I want to know.I want to know _________ __________ ___________ ___________ French.4．Have you finished your homework yet? Mr. Zhao asked Ma Chao.Mr. Zhao asked Ma Chao ______ ______ _____ ____ _____ homework yet.5．Where did she park her car? Do you know?Do you know ___________ __________ _________ her car?[知识网络]基本题型我过关根据句意及首字母提示补全单词.1．On Mid-Autumn Day Chinese people eat m______________.2．Do you hear of the L_________ Festival in Jiangxi?3．---Excuse me, where is the post office? ---Sorry, I’m a s_________ here.4．During the Spring Festival, Chinese people often get together with big family and also visit their r___________ and friends.5．My god!
