这是一份初中宾语从句的讲解与运用课件PPT

The Object Clause 宾语从句 宾语从句是主从复合句的一种。主从复合句是由一个主句和一个或一个以上的从句构成的。 主句是复合句的主体，从句仅仅是主句的一个成分，它从属于主句，不能独立。从句在全句中充当什么成分，就叫什么从句。宾语从句当中的从句在全句中作宾语。宾语从句宾 语 从 句概念：句子的宾语一般由名词、代词、 动名词或动词不定式充当，当一 个句子充当宾语时,我们把这个句 子叫做宾语从句。宾语从句的三要点： 1、引导词 2、从句语序 3、从句的时态不同引导词引导的宾语从句由从属连词that引导的宾语从句 由连接代词 Who,whom,whose,which， what 和连接副词 where,how,why,when引导的宾语从句由从属连词 whether, if 引导的宾语从句一、引导词：取决于从句的语气1.从句是陈述语气时，引导词用that.2.从句是一般疑问语气时，引导词用if或 whether.3.从句是特殊疑问语气时，引导词用特殊 疑问词。e.g. I'm afraid that you are right. I want to know if it will rain tomorrow. I didn't hear what he wanted me to do . Do you know whose bag I am carrying? He asked me if I taught English.由从属连词that引导的宾语从句注：that 在句中无词汇意义，在从句中不能充当成分，在口语当中往往省略I hear (that) ____________________________. （一小时后他会回来）He said (that) __________________________. （他非常想念我们）The teacher told us (that) ______________________________________. （地球围着太阳转） he will be back in an hour he missed us very much the earth moves around the sun由连接代词who, whom, whose, which, what及连接副词 when, where, how, why引导的宾语从句1. He asked . (谁能回答这个问题）2. Do you know_________________________. （他们在谁）3. He asked ______________________________. （谁的作业是班上最好的）4. Please tell me _______________________________. （我们什么时候开会）5. Can you tell me _______________. （他在哪儿）6. Could you tell me ____________________________. （我该怎么去车站）9. Would you tell me _________________________（为什么火车迟到了） who could answer the question whom they are waiting for whose homework was the best in the class when we’ll have a meeting where he is how I can get to the station why the train is late由从属连词whether, if 引导的宾语从句e.g. 1. I want to know _________________________________. （他是否跟我们一起去公园）2. Ask him _____________________. （他是否能来）3. I don’t know ___________________________.（是否要下雨） if (whether) he will go to the park with us whether (if) he can come whether it is going to rain or not1、当句末为or not时，引导词只能用whether而不能用if.2、在不定式前，引导词只能用whether而不能用if.例如：I haven’t made up my mind whether to go there or not.二、从句语序：一律用陈述语序 主句+引导词+主语+谓语动词+其他He asked me when I arrived in Shanghai .I want to know where they will go.Could you tell me what you are reading?I don't know where he lives .　         Could you tell me how I can get to the Science Museum ?He asked him where he came from .Did you know what’s the name of the handsome boy in the classroom yesterday？Please tell me where I can buy the beautiful flowers .请注意观察红色字体的语序三、主.从句的时态呼应1.主句是一般现在时，从句可以用任何时态。2.主句是一般过去时,从句用过去范畴的时态。3.主句是一般过去时，但从句表达的是客观真 理或自然现象时，仍然用一般现在时。He says that he is reading a book now.He said that he would work hard.They said they had been to France.The students asked me if the earth goes round the sun.　      具体的时态的变化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意思来使用需要的任何一种时态。I hear ( that ) Tom has been to Guilin twice .I hear ( that ) she will come tomorrow .I hear ( that ) Jim went to work an hour ago .I hear ( that ) he is interested in English . 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。e.g. He said ( that ) he would go to Xi’an .   He said ( that ) he was ill yesterday .   He said ( that ) he was reading a book .    He said ( that ) he had had supper already .3.当宾语从句说明的是客观存在的事实或者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。e.g. He said that the sun is much bigger than the moon .   The teacher told the students that light travels faster than sound.    The PE teacher said that doing morning exercise is useful to our health .　       标点符号 ：       宾语从句末尾的标点符号由主句决定，不受从句的限制。如果主句是陈述句或者是祈使句时用句号；而主句是疑问句时，句末则用问号。       e.g        He asked me if / whether I could help him . Do you know where Li Ping is ?       Please tell me which colour you like best .       Would you please tell the teacher how old you are ? 四、宾语从句的标点符号　        五、宾语从句的否定形式 ：        一般而言，宾语从句的否定式与一般句子的否定式是一样的。但若主句谓语动词是 think 、 expect 、 believe 、 guess 、 imagine 、 suppose 等表示“认为，猜想”的词时，一般要把宾语从句中的否定式转移到主句中。        e.g         I don’t think it’s going to rain . I don’t believe she will lend you the money .         但是，如果主句中的谓语动词是 hope ，则不适用于此规则。        e.g         I hope he won’t come .六、宾语从句与直接引语变间接引语的关系。直接引语变为间接引语之后通常都构成一个宾语从句。因此我们要掌握好宾语从句的用法必须也要熟悉直接引语变间接引语的规则。 Direct Speech and Indirect Speech引语的概念直接引述别人的原话，叫 ____________;直接引语 用自己的话把别人的话陈述出来，叫 _________。间接引语直接引语通常都用____________括起来， 引号“ ” 间接引语在多数情况下都构成一个 ________。宾语从句Direct SpeechIndirect SpeechShe said, “I like singing. ”She said, “I am waiting for a bus.”She said, “I visited Europe last year.”She said, “I have never met an American.”She said, “I will see you next week.” She said that she liked singing.She said that she was waiting for a bus. She said she had visited Europe the year before.She said she had never met an American. She said that she would see me the next week.
