英语专项语法—宾语从句.ppt

一、宾语从句的定义 宾语从句是英语中用来充当宾语的句子。宾语从句一般由“引导词+主语+谓语+其它”构成。 例如： He said (that) he wanted to stay at home. He asked me if I could help him. Can you tell me where the No.3 bus stop is? 二、 应用宾语从句时应该注意的问题： 1.宾语从句的引导词 ①宾语从句为陈述句时，用 that 引导，在口语中常常省略。 e.g. He said （ that ）he had a new dictionary . I know ( that ) Lucy can play football very well . ②当宾语从句为一般疑问句时，用 whether 或 if 引导，意为“是否”，一般两词可以互换。但是 whether 可以和 or not 连用，而 if 不能。 e.g. I want to know if she still lives there . Please tell me whether you can come or not . ③宾语从句为特殊疑问句时，用原来的特殊疑问词where ,who 等做引导词 。 I don’t know whose book it is . Do you know where our English teacher lives ? 注意：if的两副面孔,可作“如果”，“是否”两种不同的意思。例如： Do you know if he will come back next week?? If he comes back, please let me know. 2. 宾语从句的时态 1).当主句是一般现在时，从句的时态不受主句限制，从句可用任何一种时态。如： Please tell us where he will go. Can you tell me how she got to the railway station? 2) 当主句是一般过去时，从句必须用过去时的某一种时态（一般过去时， 过去进行时， 过去将来时，过去完成时） 。例如： He asked what time it was. He told me that he was preparing for the sports meet. He asked if you had written to Peter. He said that he would go back to the U.S.A. soon. 3). 当宾语从句描述的是客观事实或自然现象，真理时，不用受主句时态的限制，都用一般现在时态。例如： He said that the sun is much bigger than the moon . The teacher told the students that no news is good news . 3.宾语从句的语序 无论主句是陈述句还是疑问句，宾语从句都用陈述句语序，即是“主语在前，谓语在后”的顺序。 e.g. Could you tell me how I can get to the Science Museum ? She asked me where I came from . 1. Does Mr. Brown enjoy living in China? Could you tell us?（合并句子） ???→Could you tell us _______Mr. Brown _______ living in China? 2. When does the train leave? I want to know.（改为含宾语从句的复合句） ??? I want to know _________ the train _________. 3.What is he doing there? Mother didn‘t know. (改为含有宾语从句的复合句）Mother didnt know what _______?? ______doing there.  If enjoys when leaves he was 4.The moon moves round t
