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),如：He said, 'These books are mine.' →He said those books were his.如何变句型：①直接引语如果是陈述句，间接引语应改为由that引导的宾语从句。如：She said, 'Our bus will arrive in five minutes.' →She said that their bus would arrive in five minutes.②直接引语如果是反意疑问句，选择疑问句或一般疑问句，间接引语应改为由whether或if引导的宾语从句.如：He said, 'Can you swim, John?' →He asked John if he could swim.'You have finished the homework, haven't you?' my mother asked. →My mother asked me whether I had finished the homework.'Do you go to school by bus or by bike?' →He asked me if I went to school by bus or by bike.③直接引语如果是特殊问句，间接引语应该改为由疑问代词或疑问副词引导的宾语从句（宾语从句必须用陈述句语序）。She asked me, 'When do they have their dinner?'→ She asked me when they had their dinner.④直接引语如果是祈使句，间接引语应改为'tell(ask, order, beg等) sb.(not) to do sth.'句型。如：'Don't make any noise,' she said to the children. →She told (ordered) the children not to make any noise.'Bring me a cup of tea, please,' said she. →She asked him to bring her a cup of tea.⑤直接引语如果是以“Let's”开头的祈使句，变为间接引语时，通常用“suggest +动句词（或从句）。”如：He said, ' Let's go to the film.' →He suggested going to the film.或He suggested that they should go to see the film.引述别人的话有两种方式：一是使用引号引出人家的原话，这叫做直接引语；一是用自己的话把人家的话转述出来，这叫做间接引语。例如：John said, 'I'm going to London with my father.'约翰说：'我要和父亲到伦敦去。'（引号内是直接引语）John said that he was going to London with his father.约翰说，他要和他父亲去伦敦。（宾语从句是间接引语）</p 产品：澳博培训供货总量：不限产品价格：议定包装规格：不限物流说明：货运及物流交货说明：按订单
