11、Tom is a good student.1.确定连接词确定连接词(根据从句句式根据从句句式)从从 句句 的的 句句 式式连连 接词接词 陈陈 述述 句句that一般疑问句一般疑问句if(whether)特殊疑问句特殊疑问句特殊疑问词特殊疑问词祈使句祈使句肯定句肯定句to+to+动词原形动词原形否定句否定句notto+动词原形3.确定从句的时态确定从句的时态(根据主句时态根据主句时态)主句时态主句时态从从句句时时态态连连接接前前连连接接后后一般现在时一般现在时时态保持不变时态保持不变一般过去时一般过去时一般现在时一般现在时一般过去时一般过去时一般过去时一般过去时一般过去时一般过去时一般将来时

12、一般将来时过去将来时过去将来时现在进行时现在进行时过去进行时过去进行时现在完成时现在完成时过去完成时过去完成时2.确定从句语序确定从句语序(把从句变成陈述句把从句变成陈述句)3.确定从句的时态确定从句的时态(根据主句的时态而定根据主句的时态而定)直接引语变间接引语与宾语从句的关系直接引语变间接引语与宾语从句的关系1.当主句的谓语动词是一般现在时或一般将来时，宾语从句的谓语动词可以用所需要的任何一种时态。2.当主句的谓语动词是一般过去时，宾语从句的谓语动词要用相应的过去时态，但当宾语从句叙述的内容为客观真理时，仍然用一般现在时。e.g.Theteachersaidthatthemoonmoves

13、aroundthesun.注注 意意1.三姊妹三姊妹宾语从句根据引导词的不同可分为三种类型：宾语从句根据引导词的不同可分为三种类型：1.由由that引导的宾语从句。如：引导的宾语从句。如：We knew that we should learn from each other.2.由由if/whether引导的宾语从句。如引导的宾语从句。如：Please tell me if/whether you have been to America.3.由由who，where，how等连接代词或连接副词引导的等连接代词或连接副词引导的宾语从句。如：宾语从句。如：Can you tell me how

14、I can get to the nearest post office？2.过三关1.1.引导词关引导词关如果从句是陈述句，引导词用如果从句是陈述句，引导词用thatthat（thatthat在口语或非正式文体中常省略在口语或非正式文体中常省略）；）；如果从句是一般疑问句，引导词用如果从句是一般疑问句，引导词用if/whetherif/whether；如果从句是特殊疑问句，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引导词用由疑问词转换而来的疑问代词词/副词副词(who,whomwho,whom,which,whose,which,whose,what,how,when,what,

15、how,when,where,whywhere,why)2.语序关语序关陈述句变为宾语从句，语序不变，即仍用陈述语序。陈述句变为宾语从句，语序不变，即仍用陈述语序。如：如：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。如：序变为陈述语序。如：Does he work hard？I wonder.I wonder if/whether he works hard.When did he lea

16、ve？I dont know.I dont know when he left.3.时态关时态关如果主句是现在的时态，从句的时态可根据实际如果主句是现在的时态，从句的时态可根据实际情况而定。如：情况而定。如：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。如：定要用过去的某种时态。如：He said（that)he had been there.注意：如果宾语从句表述的是客观真理、自然现象注意：如果宾语从句表述的是客观真理、自然现象等时，不管主句

17、是什么时态等时，不管主句是什么时态，从句都要用一般现从句都要用一般现在时。如在时。如：He said that light travels much faster than sound.4.从句的简化从句的简化1.当主句谓语动词当主句谓语动词是是find，see，watch，hear等感官动词时，从句常简化为等感官动词时，从句常简化为“宾语宾宾语宾补补”结构，宾补为不带结构，宾补为不带to的不定式或的不定式或V-ing形式。形式。如：如：She found that the wallet lay/was lying on the ground.She found the wallet lie/

18、lying on the ground.2.当主句谓语动词是当主句谓语动词是hope，wish，decide，forget，plan，agree等，且主句主语与等，且主句主语与从句主语相同时，从句可简化为不定式结构。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.在连接代词在连接代词/副词引导的宾语从句中，当从句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，宾语从句可主语与主句主语或间接宾语一致时，宾语从句可简化为简化

19、为“连接代词连接代词/副词不定式副词不定式”结构。如：结构。如：Can you tell me how I can get to the station？Can you tell me how to get to the station？5.宾语从句的否定转移宾语从句的否定转移 当主句的谓语动词是当主句的谓语动词是think,believe,suppose,imagine 时，并且时，并且它的主语是第一人称时，它的主语是第一人称时，如果如果从句的谓语动词表示否定意思，通常我们要将从句的谓语动词表示否定意思，通常我们要将否否定词转移到主句的谓语动词上定词转移到主句的谓语动词上，即通过否定主句，即

20、通过否定主句的谓语动词来否定从句的谓语动词。这中语法现的谓语动词来否定从句的谓语动词。这中语法现象就是象就是宾语从句的否定转移。宾语从句的否定转移。I dont believe she will tell you about it.We dont think he is right.We dont believe that he did the job himself.6.宾语从句反意问句及应该的注意问题宾语从句反意问句及应该的注意问题通常反意问句部分的构成通常反意问句部分的构成,常和主句的主谓常和主句的主谓 保持一致保持一致:WeallknowthattheycomefromAmerica,

21、dont we?Yousawthatthefirehadbeenputout,didnt you?Hethinksthatwemissedthetrain,doesnt he?但是当主句部分的主谓是但是当主句部分的主谓是:“Ithink,Idontbelieve”时时,这时的反意问句部分这时的反意问句部分,则要和从句的主谓保持一致则要和从句的主谓保持一致:Ibelieveyoucanwinthegame,cant you?Idontguessthattheirteamwillwin,will it?IdontthinksheisfromCanada,is she?注意：两副面孔注意：两副面孔i

22、f和和when既能引导时间状语从句，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，它们究竟属于认真分析一下，它们究竟属于“两副面孔两副面孔”的哪一副。的哪一副。如如：Ifitrainstomorrow，Iwontcome.（时间状语从句）（时间状语从句）I dont know if it will rain tomorrow.（宾语从句）（宾语从句）P89 B1 Complete the object clauses with the words from the box.how when whether why what wher
