Our teacher told us that the earth goes around the sun. I dont know if he will come tonight.,找出宾语从句,We are proud of that Beijing is one of the biggest cities in the world .,宾语从句三要素,引 导 词,时态呼应,陈述语序,that if/whether 特殊疑问词,引导词+主语+谓语+其他,当陈述句充当宾语时， 由 _连接。,(1).

Do you know?,Do you know if /whether Kate gets up early?,(1) Is Jim a good student? I dont know,I dont know if /whether Jim is a good student.,.当一般疑问句充当宾语，由_ 连接,if/whether,注意：宾语从句末尾的标点符号由主句决定，不受从句的限制.,3.当特殊疑问句充当宾语时，由 _ 连接,Eg:,1.What is she doing? Can you tell me?,Can you tell me what she is doing?,2.Where does she live? Do you know?,Do you know where she lives?,特殊疑问词,(what,who,how,where,when,what time,how ofen,how much.),3.

He asked me if I could get to the bus station on time.,三. 宾语从句的语序-陈述语序,无论主句是陈述句还是疑问句，宾语从句都是运用陈述句的语序，即是“主语在前，谓语在后”的顺序。,_,_,_,注意：疑问词作主语时,句子本身为陈述语序;所以,在宾语从句中 都不需要改变语序.,1. What's wrong with you ? I wonder _.,2. What happened to you ? He asked me _.,3. Which is the way to the station? Please tell me _.,what's wrong with you,What happened to you,Which is the way to the station,主句时态,从 句 时 态,连 接 前,连 接 后,一般现在时,时态由从句决定,一般过去时,一般现在时work,一般过去时worked,一般过去时 worked,过去完成时had worked,一般将来时will work,过去将来时would work,现在进行时is working,过去进行时was working,现在完成时have worked,过去完成时had worked,四.宾语从句的时态变化,填一填,was,is,Will cook,is singing,has been,was playing,had learned,1.当主句是一般现在时，宾语从句的时态不作限制，我们可以根据句子的需要使用任何一种时态。 （需要性原则）,2.当主句是一般过去时的时候，宾语从句必须运用相应的过去的某一种时态，从而达到主句和从句的相互一致。（呼应性原则）,1) He will go to Hong Kong . 2) He is sick. 3) He is reading a book . 4) He has finished his work.,1) He to Hong Kong .,2) He sick. 3) He a book . 4) He _ his work.,辨一辨,would go,was,was reading,had finished,3.当宾语从句说明的是客观存在的真理时，就不用受到主句时态的限制，仍是用一般现在时态。（特殊性原则）,He told me (that)Summer is after Spring .,I was told (that)the sun is much bigger than the moon.,My parents told me (that) no news is good news.,五.宾语从句的难点：,if与whether的区别 when与if 引导的宾语从句和状语从句 宾语从句与简单句的互换,一般情况下，if 和whether可以互换，但以下3种 情况只能用whether： 1. 与or not连用： I don't know whether he will come or not tomorrow 2. 在介词之后： It depends on whether it is going to rain. 3. 在不定式之前： We havent decided whether to go there. 4.作主语只能用whether Whether he will come is not decided.,比一比 I dont know where I should go.
