Kangkang asked the old lady Pay attention!注意：直接引语变为间接引语时：如果直接引语是陈述句，则变为say引导的宾语从句；如果直接引语是疑问句, 则变为ask引导的宾语从句。同时要注意当主句是一般过去时 时，从句的时态也要相应的变为过去的某种时态。还要注意人称 呦！ 2. Kangkang asked the old lady 直接引语变为间接引语时: 要注意时态 和人称 的变化，如果是特殊疑问句还要注意变回陈述句语序。 3. Kangkang asked the old lady 如果直接引语是一般疑问句，应该变回陈述句语序，同时前加if/whether。还应当注意时态 和人称。直接引语变为间接引语的转化中还需要注意下列的词语变化！a.指示代词this that these those b. 表示时间的词now then today that day yesterday the day beforelast week(month ,etc.) the week(month ,etc.) before three days (a year ,etc.) ago three days (a year. etc.) before tomorrow the next (following ) day next week (month,etc.) the next (following ) week (month,etc.) c. 表地点的词Here thered. 动词bring take come go三、affect，effect和influence的区别区别一：affect 与 effect 均为“影响”，区别是：前者是动词(Vt)，主要指一时的影响，着重动作，影响不分好坏；后者是名词(可数或不可数)，两者的关系大致为：affecthave an effect on。如：To affect a policy is to have an effect on it. 影响一项政策就是对该政策具有一种影响。The news did not affect her at all.The news had no effect on her at all. 这条消息对她没有一点影响。注：effect 有时虽用作动词(及物)，但不表示“影响”，而表示“实现”或“产生”等。如：They affected their escape in the middle of the night. He effected great changes in the company. 他使公司发生了巨大的变化。 区别二：influence 表示“影响”，主要指对行为、性格、观点等产生间接的或潜移默化的影响。可用作动词”(Vt)或名词(通常【U】，但有时可连用不定冠词a/an)。如：What you read influences your thinking. 你读的东西对你的思想有影响。Television has a strong influence on people. 电视对人有很大的影响。Its clear that her painting has been influenced by Picasso. 她的画显然受了毕加索的影响。四、练习直接引语和间接引语的相互转换。1. “I often play the piano.” Tina said.
