宾语从句：在句子中起宾语作用的从句叫宾语从句 宾语从句三大考点：时态、语序、引导词 宾语从句的时态：（1） 如果主句是现在时，那么从句可以根据需要选择任意时态；练：我记得他昨天给了我一本书；I remember that he （give） me a book yesterday.他告诉我他明天要动身前往纽约了；He tells me that he （leave） for New York tomorrow.我发现他正在看别人的信件。I find that he （read） other s letters.（2） 如果主句是过去时（某种时态），那么从句一般要用过去的某种时态 （般过去时，过去进行时，过去将来时）练：他告诉我他将会参加跳高比赛；He told me that he （take） part in the high jump.（3） 如果宾语从句表示的是客观事实或真理，即使主句是过去时，从句也用一般现在时；练：老师告诉我们地球绕着太阳转Our teacher told us that the earth （travel） around thesun宾语从句的引导词:引导词引导词的作用例句that本身无意义，只起连接 作用，在口语中可省略；He said (that) Kate was good at swimmi ng.what, which, who,whose在从句中作一定的成分，I don t know what they are等连接代词如主语、宾语、定语等；going to do.He asked mewhosebook this was.when（表时间），where（表 地点），why（表原因）, how（表方式）等连接副词在从句中作状语Could you tell me where you are from?if/ whetherHe asked mewhether / if/ whetherHe asked mewhether / if Miss Gao子成分，但不能省略； was a teacher.1、 当宾语从句是由陈述句转化而来时，用 that引导，口语中往往省略；“She is a good girl, ” the teacher tells us.f The teacher tells us she is a good girl.【注意】引导词that用于下列情况时不能省略；当宾语从句的主语是that时；例：He says that that is a useful book.当从句前有插入语时；例: It says, on the car, that it is made in China.当宾语从句中含有主从复合句时；例: I m afraid that if you lost the book, you must pay for it. 当有两个或多个宾语从句由并列连词连接时，除第一个从句中的 that 可以省略外物业经理人，其余从句中的that都不可以省略；例: He said (that) the film was very interesting and that he enjoyedsee ing it very much.把一般疑问句变为宾语从句时，用 whether或if引导；练： “ Are you from Japan? ” he asked me.f He asked me I (be) from Japa n.“ Do you like watchi ng TV? ” he asked me.f He asked me I (like) watch ing TV.【注意】a. 一般情况下，whether和if可以互换。但是以下三种情况只能用 whether.当宾语从句中出现了 or not时例: Let me know whether you can come or not.当在介词之后，做介词宾语时例: I m thinking of whether I should go fishing ./ It depends onwhether it will be sunny tomorrow.当与不定式连用时例： I don t knowwhether to accept or refuse. / I mnot sure whether to play basketball or go home.b. if 在宾语从句中，意为“是否” ，等同于 whether ； 在条件状语从句中，意为“如果” ，时态遵循“主将从现” ；3、把特殊疑问句变为宾语从句时，连接词就用原来的特殊疑问词，但一定要注 意用陈述语序；练： When did he leave for Japan? Could you tell me?f Could you tell me he (leave) for Japan?Who is our English teacher ? Do you know?fDo
