2021年中考英语语法复习（ppt课件）-宾语从句详解.pptx

1、Review of Object Clause Remember that life is full of ups and downs,and without the downs,the ups would mean nothing.铭记，生活充满起起伏伏，而若没有了人生的低谷，那站在高处亦失去了意义。Definition&Structure定义和结构I believe you.在句子中起宾语作用的从句叫做宾语从句主语谓语宾语I believe (that)you can fly.主语谓语连接词主语谓语宾语从句宾语从句常放在say,ask,tell,hope,think,believe等谓语动

2、词后面结构：主句+连接词+宾语从句主句连接词Observe the following object clauses.That comes from what you eat.My father thought that if he made a pot of pinto beans（花斑豆）,big enough,we would eat them all week.We had beans when my mother used to go to visit her sisters in Washington D.C.Conjunction连接词从句句式连接词(引导词)thatif/whe

3、therwhat/when/where等特殊疑问词宾语从句要素一：连接词（引导词）主从复合句需要连接词(引导词)做桥梁,根据不同句型采取不同的连接词(引导词)。that 无实义,在从句中不作任何成分，用来引导表示陈述句，that在句中可省略I think that this book is very interesting.I know that its very important to learn English well.Remember that life is full of ups and downs,and without the downs,the ups would mean

4、 nothing.if/whether中文含义为“是否”，用来引导一般疑问句，在从句中不作任何成分 Do you know if/whether there is a restaurant near here?I dont know whether he will come here or not.It depends on whether he is coming.He doesnt know whether to accept the invitation.如果从句中含有or not时，只能用whether而不用if连接词前有介词时，只能用whether而不用if与动词不定式连用时，只能用

5、whether而不用ifwho,what,which,whose,where,when,why等特殊疑问词用来引导特殊疑问句，在从句中充当成分 I asked where he lived.I asked Tom how he went to school.She wants to know what he has done for the exam.I dont know why he leaves.I wondered when she died.Classification分类动词的宾语从句I hear that he has passed the exam.介词的宾语从句We are

6、talking about whether we admit students into our club.That comes from what you eat.形容词的宾语从句I am sure that I will pass the exam.Word Order语序不管整个句子是表示肯定还是表示疑问，宾语从句都采用陈述语序：主+谓+其他。I dont know when I can get the result of the test.Can you tell me where I can get my car repaired?特殊情况Do you know who is on

7、duty today?Can you tell me which is the way to the cinema?I wonder what is wrong with you?who,which,what既是引导词，在从句中也是主语，本身就是陈述语序。在变成宾语从句时，语序无变化Tense时态主现从不限I hope that you will have a good time tomorrow.He says that he is listening to the weather reportMary tells me that she was born in 1985.如果主句的谓语是一

8、般现在时，则宾语从句可根据实际情况选用适当的时态。主过从必过 He said that he bought a new dictionary I knew that they were studying English如果主句的谓语是一般过去时，则宾语从句也必须改为相应的过去时态（一般过去时、过去进行时、过去将来时等）。真理永一现 The teacher said that the earth goes around the sun.My dad told me(that)light is faster than sound.但如果宾语从句所表达的是客观事实、真理、自然现象、名言、警句、谚语等

9、时，从句则用一般现在时，不受主句时态的限制。Difficulties难点1、当宾语从句的主语和主句的主语相同，宾语从句可转化为含有不定式的简单句，即“引导词to动词原形其他”。(1)I didnt know how I could do it.=I didnt know how to do it.(2)Mike didnt decide what he would buy.=Mike didnt decide what to buy.2、宾语从句的否定转移(否定前置)：当主句的主语是第一人称，且谓语动词是think，believe，suppose，expect等时，如果宾语从句是否定意义，否定

10、词要移到主句的谓语动词之前。(1)我认为他不对。I dont think he is right.(2)我相信他们还没有完成工作。I dont believe they have finished the work.3、if和when既可以引导宾语从句，也可以引导状语从句，应注意它们在两种从句中的意思和用法的不同。(1)Do you know when he will come back tomorrow？(宾从：主现从不限)你知道他明天什么时候回来吗？Sorry,I dont know.When he comes back,Ill tell you.(状从：主将从现)对不起，我不知道。等他回

11、来了，我就告诉你。(2)I dont know if he will come tomorrow我不知道明天他是否会来。(宾从：主现从不限)He will come if it doesnt rain如果不下雨，他会来的。(状从：主将从现)Summary TenseConjunctionClassificationWord OrderDifficultiesDefinition&StructureHomework单项选择()1.Could you tell me _ youd like me to pay you?Youd better use mobile payment.I dont ca
