1、如果从句是陈述句,引导词用that(that在口语或非正式文体中常省略);如果从句是一般疑问句,引导词用if/whether;如果从句是特殊疑问句,引导词用由疑问词转换而来的疑问代词/副词。2. 语序关陈述句变为宾语从句,语序不变,即仍用陈述语序。He is an honest boy. The teacher said. The teacher said(that)he was an honest boy.一般疑问句和特殊疑问句变为宾语从句,语序变为陈述语序。Does he work hard?I wonder.I wonder if/whether he works hard.When d
2、id he leave?I dont know. I dont know when he left.3. 时态关如果主句是现在的时态,从句的时态可根据实际情况而定。I have heard(that)he will come back next week.如果主句是过去的某种时态,那么从句的时态一定要用过去的某种时态。He said(that)there were no classes yesterday.注意:如果宾语从句表述的是客观真理、自然现象等时,不管主句是什么时态,从句都要用一般现在时。He said that light travels much faster than sound
3、.三、人称的变化和标点的使用1. 从句的主语如果是第一人称,变为宾语从句则与主句的主语一致;如果是第二人称,则与主句的宾语一致;如果是第三人称,不用变化。“May I use your knife?”He asked me. He asked me if he might use my knife.“Do you know her telephone number?”He asked me. He asked me if I know her telephone number.2. 宾语从句的标点均由主句决定。主句是陈述句,用句号;主句是疑问句,用问号。Who will give us a t
4、alk?I dont know. I dont know who will give us a talk.Do you know?Where does he live?Do you know where he lives?四、两副面孔if和when既能引导时间状语从句,又能引导宾语从句。因此,遇到它们就要认真分析一下,它们究竟属于“两副面孔”的哪一副。If it rains tomorrow,I wont come.(时间状语从句)I dont know if it will rain tomorrow. (宾语从句)五、从句的简化1. 当主句谓语动词是find,see,watch,hear等
5、感官动词时,从句常简化为“宾语宾补”结构,宾补为不带to的不定式或V-ing形式。She found that the wallet lay/was lying on the ground. She found the wallet lie/lying on the ground.2. 当主句谓语动词是hope,wish,decide,forget,plan,agree等,且主句主语与从句主语相同时,从句可简化为不定式结构。She agreed that she could help me with my maths. She agreed to help me with my maths.3
6、. 在连接代词/副词引导的宾语从句中,当从句主语与主句主语或间接宾语一致时,宾语从句可简化为“连接代词/副词不定式”结构。Can you tell me how I can get to the station?Can you tell me how to get to the station?中考真题演练1.重庆A卷-Do you know _?-Let me see.
