初中英语语法宾语从句讲解，专项练习及答案注意！宾语从句小口诀：
宾语从句三注意，时态语序引导词；
主句一般现在时，从句不需受限制；
主句一般过去时，从句须用相应时；
陈述句转化that引，一般疑问句用if/whether,
特殊问句疑问词，引导词后陈述式。
一、基本讲解
1 概念:在句中担当宾语的从句叫宾语从句，宾语从句可作谓语动词的宾语，也可做介词的宾语。eg, He said he was good at drawing. (动词宾语)
He asks him how long Mike has been down . (动词宾语)
Miss Zhang is angry at what you said. (介词宾语)
2.连接词
(1) .陈述句转化成宾语从句时，引导词用that,口语中常常省略。
e.g, She told me (that) she would like to go with us.
(2)以whether 或if 引导的宾语从句, 主要用来引导一般疑问句意思或选择疑问句意思的宾语从句，从句同样是陈述语序
eg, I wonder if /whether u have told the new to Li Lei .
注意：一般情况下，whether 和if 可以互用，但有些情况例外。
a. 当从句做介词的宾于是只用whether 不用if
eg, We are talking about whether we'll go on the pinic.
b. 引导词与动词不定式或not 连用时，只用whether.
eg, Please let me know what to do next.
Could you tell me whether u go or not?
c. if当如果讲时，引导的是条件状语从句，这时不能用whether.
(3).特殊疑问句转化成宾语从句时，引导词用特殊疑问词；引导词后要用陈述句语序。
E.g. Could you tell me what's the matter\wrong with you?
特殊情况：：当do you think后接特殊疑问句转化成宾语从句时，句式结构应为引导词＋do you think＋陈述句语序。
3.宾语从句时态
a.当主句是一般现在时，一般将来时或祈使句时，从句不受主句的限制，根据自身的需要选用相应的时态。例如：
Do you know（if/whether he has seen the film）?
b.当主句是一般过去时，从句要用过去时的相应时态。例如：
I didn't know （if/whether he had seen the film.）
注意：当主句是一般过去时，而从句表示的是客观真理，自然现象，科学原理，格言等，从句仍然要用一般现在时。例如：
He said （that the earth moves round the sun.）
The teacher told us （that light travels much faster than sound.）
4.、人称的变化和标点的使用
a.从句的主语如果是第一人称，变为宾语从句则与主句的主语一致；如果是第二人称，则与主句的宾语一致；如果是第三人称，不用变化。如：
?May I use your knife？?He asked me.
→He asked me if he might use my knife.
?Do you know her telephone number？?He asked me.
→He asked me if I know her telephone number.
b. 宾语从句的标点均由主句决定。主句是陈述句，用句号；主句是疑问句，用问号。如：
Who will give us a talk? I don’t know. →I don’t know who will give us a talk.
Do you know？Where does he live? →Do you know where he lives?
二、宾语从句的转化
1.2. 当主句谓语动词是hope，wish，decide，forget，plan，agree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。如：
She agreed that she could help me with my maths.
→She agreed to help me with my maths.
2.当主句的谓语动词是know, learn, forget, remember, decide等后面带特殊疑问句转化的宾语时，主从句的主语也须一致这时从句可以简化成?疑问词＋不定式结构?。例如：
I don't know which sweater I should buy.→I don't know which sweater to buy.
3.当主句的谓语动词是ask，tell, show, teach等后面带双宾语时，从句的主语和间接宾语一致，且从句是由特殊疑问句转化来时，从句可以转化成?疑问词＋不定式结构?,或者在连接代词/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，宾语从句可简化为?连接代词/副词＋不定式?结

一、宾语:是表示及物动词的动作对象，放在及物动词后面。 例如：She plays the piano. He often helps me. I like watching TV. 二、宾语从句：从句在句中起宾语的作用，就叫宾语从句。 三、宾语从句的时态： 当主句为一般现在时，从句可用任何一种时态；She says that she will come.她说她会来。 当主句为一般过去时，从句用过去相应的时态。She said that she wanted to have a try. 她说过她想试一试。 当从句客观真理时，从句用一般现在时。Our teacher said the earth goes around the sun.我们的老师说过地球围绕着太阳转。 1、陈述句变宾语从句：用that引导，通常可以省略。 翻译：我认为你是对的。_____________________________________________ 她说她是个学生。_____________________________________________ 2、一般疑问句变宾语从句（…...吗？） 当一般疑问句变成宾语从句时，我们需要用if或whether来引导。 例如：Is it true？这是真的吗？→_____________________________________________我想知道是否是真的。 Are you a student？你是一个学生吗？→_____________________________________________他问我是不是学生。 注意：一般疑问句中的疑问语序要变成_________语序。 3、特殊疑问句变宾语从句 用特殊疑问句本身的疑问词引导，特殊疑问句中的疑问语序要变成陈述语序。 如：Do you know？Where can I park my car？（两个特殊疑问句） 将两个句子合成宾语从句：_____________________________________________ 注意：特殊疑问句中的疑问语序也要变成_________语序。 专项练习 一、根据宾语从句的时态，用所给动词的正确形式填空. 1. We are sure that he _________ (go) to school tomorrow. 2. Do you know who ________ (be) the first man to walk on the moon 3. Could you tell me where the post office ______ (is) 4.

She doesn't know whether _____________ (go) or wait. 二、请将以下句子转换成宾语从句。（考虑三方面：引导词、时态、语序） 1. He will come back in a week.→I think _________ he ______________ ______________ back in a week. 2. Who is he looking for?→Do you know _________ ______________ _________ looking for? 3. Why is the plane late? →I didn’t know _________ the plane ______________ ______________. 4. He has already come back. →He told me _________ he ______________ already come back. 5. How can I get to the Summer Palace? →Could you tell me _________ _________ ______________ get to the

初中英语宾语从句讲解 一、宾语从句的概念 宾语从句属于名词性从句，在句中作主句的宾语。 eg. We know Mr. Green teaches English. She asked if these answers were right. 二、宾语从句三要素 引导词（连接词） 语序 时态 三、重难点掌握 （一）引导词 1．由从属连词that引导的宾语从句 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2。由从属连词whether, if 引导的宾语从句（重点掌握） 由从属连词whether, if 引导的宾语从句 if/ whether “是否”，说明对陈述的事物不明确或不清楚。常用在ask, wonder, can(could) you tell me 等后。 1. I want to know whether/if he is right. 2. I Ask him whether/if he likes me_. 3. I wonder _whether/if we can get there. 4. Could you tell me whether/if that film is interesting ? ◆只能用whether不能用if的情况 1.在介词后面： I’m thinking of whether we should go fishing. We are worried about whether it will rain tomorrow. 2.在动词不定式前： They asked me whether to go skating. 3.当与or not连用，或提出两种选择时: I don’t know whether he’s free or not. Mary asked whether I was doing my homework or not. Tell me whether you’d like to go shopping or tidy the room. 4.宾语从句提前时： Whether this is true or not, I can’t say.

宾语从句专项讲解及练习（有答案）宾语从句 一、基本概念 定义：在句子中起宾语作用的从句叫做宾语从句。 二、宾语从句分类 动词的宾语从句 e.g.He asked whose handwriting was the best. 介词的宾语从句 e.g.It depends on whether it is going to rain. 形容词的宾语从句,即系词+心理状态形容词+宾语 e.g I am afraid that he can't finish the work. 三、宾语从句用法详解 1.宾语从句的语序 宾语从句的语序应为陈述句的语序。即主语+谓语的顺序。如： I hear (that) physics isn’t easy. I think (that) you will like this school soon. Can you tell me how I can get to zoo? Please tell me when we’ll have the meeting. 注意：在宾语从句中带有特殊疑问词但句序不变的句子： What’s the matter? What’s your trouble? What’s your problem?
What’s up? What’s your name? 典型例题 1.Can you tell me ____? A .whom do we have to see B. whom we have to see 2. The teacher asked the students ____. A. what they were doing B. what were they doing 3. She wants to know____. A. where does he live B. Where he lives 4. Her father asked _____. A. who the tallest is B. who is the tallest 5.Do you know ____? A. what is on the desk B . what on the desk is 答案：BABBA 2.宾语从句的时态 1）. 若主句时态是一般现在时，宾语从句该用什么时态就用什么时态。即从句可用所需任何时态，如： I don’t think (that) you are right. Can you tell me how I can get to the railway station? He says Mary is playing with the cat . He says Mary often plays with the cat. He says Mary will play with the cat. I think he left yesterday morning. 2）. 如果主句的时态是一般过去时，宾语从句只能用相应的过去时态（一般过去时，过去进行时，过去将来时，过去完成时）。例如： He asked what time it was.
宾语从句 1、基本概念 1.1 宾语 veiw 请用下划线划出下列句子中的宾语： I know him. He runs a big shoe factory. We grow lots of vegetables. He told me the news. She promised me a nice gift to me on Christmas Day. I hear that you have passed the examination. 1.2 什么是宾语从句？ 当一个句子充当宾语时，这个句子就称之为宾语从句。宾语从句可作谓语动词 的宾语，也可做介词的宾语。例如： He said he was good at drawing. （ 动词宾语 ） He asks him how long Mike has been down . （ 动词宾语 ） Miss Zhang is angry at what you said. （ 介词宾语 ） 1.3 宾语从句的分类 ：宾语从句根据引导词的不同可分为三种类型： 1. 由 that 引导的宾语从句。如： We knew (that)we should learn from each other. 2. 由 if/whether 引导的宾语从句。如： Please tell me if/whether you have been to America. 3. 由 who ， where ，how 等连接代词或连接副词引导的宾语从句。 Can you tell me how I can get to the nearest post office 2、引导词 （1） 以 that 引导，主要用来引导陈述句形式的宾语从句， 略。 I know (that) he is a Canadian athlete. Do you think (that) the children need to write a song? Maria says (that) she doesn 't like the uniforms. She told me (that) she would like to go with us. (2) 以 whether 或 if 引导，主要用来引导一般疑问句意思或选择疑问句意思 的宾语从句。 whether 和 if 都可以引导宾语从句，表示“是否”，两者可以互换使用。 如： that 可以省
宾语从句 一、定义：在复合句中用作宾语的从句叫做宾语从句。在复合句中宾语从句作主句中谓语动词、介词的宾语。 在及物动词的后面可以接一个名词来充当宾语，如：I know the man. 而这时也可以用一个句子来充当宾语，如：I know that the man is a policeman. 主句引导词从句 宾语从句三大块: 1. 引导宾语从句的连接词（从属连接词和连接代词）； 2. 宾语从句的语序； 3. 宾语从句的时态。 二、宾语从句的引导词（连接词） 作用有无意义在从句中 所做成分从属连接词that 只起连接作用无无 Whether/if 起连接作用有（表示是否）无 连接词连接代 词What 连接+从句中做成分什么（指物）主，宾，表Which 连接+从句中做成分哪一个（指物）主，宾，表who 连接+从句中做成分谁（指人主格）主，表whom 连接+从句中做成分谁（指人宾格）宾whose 连接+从句中做成分谁的（指人所有格）定 连接副词Where 连接+从句中做成分地点状语When 连接+从句中做成分时间状语Why 连接+从句中做成分原因状语How 连接+从句中做成分方式状语 1.陈述句充当宾语从句时，用that引导，that无词义，在口语或非正式文体中常省略。如：My teacher said I was a good boy.老师说我是个好男孩。 She doesn’t know (that) she is seriously ill. I am sure (that) he will succeed. 2.当由一般疑问句充当宾语从句时，用if或whether引导，意为“是否”。如： I don’t know

【初中英语】宾语从句章节知识点总结及练习测试题含答案解析 一、初中英语宾语从句 1．—We can use VQR code（二维码） to find information on the cell phone now.—Really? Can you show me _____________it’? A．how I can use B．how can I use C．why can I use D．what I can use 【答案】A 【解析】 句意：--我们现在可以在手机上使用二维码找到信息。--真的吗？你能教我如何使用它吗？根据Can you show me ，可知本句考查了宾语从句的用法．在宾语从句中所使用的语序应该是陈述句语序，选项BC是疑问句语序，排除掉．再根据Can you show me it，可知这里有it，所以宾语从句的引导词不能再有what．故选A。 2．—I’m sorry about yesterday. —Don’t worry about it. It’s never just one person’s fault. We should think abo ut______better next time. A．how can we do it B．how we can do it C．how can they do it D．how they can do it 【答案】B 【解析】 【详解】 句意：——昨天我很抱歉。——不用担心。它永远不只是一个人的错。我们应该考虑下一次如何做得更好。考查宾语从句。宾语从句需用陈述句语序，AC都是疑问句语序，可排除。It’s never just one person’s fault. 不只是一个人的错，意思是“我们大家都有责任”；根据句意语境，可知they不合句意，故选B。 3．—I'm going to give a talk on the Dragon Boat Festival to the exchange students. —Great! But don't forget to tell them __________. A．what should they eat at the festival B．what kind of race is often held C．why people enjoy the full moon D．how do people celebrate it 【答案】B 【解析】 试题分析：句意：――我要给交换生们作一份有关端午节的报告。――好极了。但是不要忘了告诉他们：A.whatshouldtheyeatatthefestival.他们在节日里应该吃什么； B.whypeopleenjoythefullmoon为什么人们喜欢圆月； C.whatkindofraceisoftenheld经常举行的什么比赛； D.Howdopeoplecelebrateit人们怎样庆祝。宾语从句需要用陈述句语序，可以排除掉A、D,再根据常识可知龙舟节跟欣赏满月没有关系，排除掉C，所以正确答案选B。
初中英语语法宾语从句讲解 小口诀： 宾语从句三注意，时态语序引导词；主句一般现在时，从句不需受限制； 主句一般过去时，从句须用相应时；陈述转化that引，一般疑问用if/whether, 特殊问句疑问词，引导词后陈述式。 一．基本讲解来源：直接引语变间接引语 概念:在句中担当宾语的从句叫宾语从句。 Eg: He said,“I am good at drawing”. He said he was good at drawing. (动词宾语) 1.引导词 (1) that引导宾语从句时，通常用陈述句充当, that可省略。 Eg: She said,“I want to go there ”She said (that) she wanted to go there. (2) whether 或if 引导的宾语从句,由一般疑问句/选择疑问句充当，陈述语序。 Eg: “Are you interested in geography?” she said. She asked if/whether I was interested in geography. I wonder if /whether she has told the new to Li Lei . I’m not sure whether he will come or not. 注意：一般情况下，whether 和if 可以互用，但有些情况例外 a. 介词短语后只用whether 不用if eg: We are talking about whether we'll go on the panic. b. 引导词与动词不定式或or not 连用时，只用whether. eg:I can’t say whether or not he will come on time c. if当如果讲时,引导的是条件状语从句，表示‘如果’，不能用whether. Eg: If you want to be a good teacher, it will take times. Whether you can succeed depends on how much effort you pay. (3).特殊疑问词引导宾语从句时，不可省略，陈述句语序。 特殊疑问词为：how , when, where, why ,which whose. E.g. ‘What do you want?’ He asked. He asked me what I wanted. I have no idea where he is now. I don’t know how to deal with it. He asked whose handwriting is the best in the class. 2.宾语从句时态 a.主句为一般现在时，从句不受主句的限制 eg: Do you know if/whether he has seen the film? I’m sorry to hear that your father is ill. She says she is going to go to Beijing next week. He tells me that his sister came back yesterday. b.当主句是一般过去时，从句用过去的相应某种时态 She didn’t know why the boy was late again. (过去一般) I didn't know if/whether he had seen the film.（过去完成） I wondered when she was going to America.（过去将来） 注意：当主句是一般过去时，而从句表示的是客观真理，自然现象，科学原理，格言等，从句仍然要用一般现在时。例如： Eg: He said （that the earth moves round the sun. / that light travels much faster than sound.）The teacher told us （seeing is believing.）
宾语从句专项练习(含答案)宾语从句：用一个完整句子充当前面某个谓语动词的宾语对象 不论宾语从句由什么引导词引导，也不论主句是陈述句还是疑问句，宾语从句一律用陈述句语序，即“引导词＋主语＋谓语＋其他”结构。判断正误： We don't know when will they arrive. ( ) We don't know when they will arrive. ( ) Could you tell me who is he waiting for? ( ) Could you tell me who he is waiting for? ( ) 注意：特殊疑问词作主语时，如果语序本来就是“主语＋谓语”结构，则语序不再变化。如： Please tell me. Who will give us a talk this afternoon？(合并为一句) →Please tell me _____________us a talk this afternoon. 宾语从句在时态上应遵循时态呼应原则 在宾语从句中，谓语动词时态要受到主句谓语动词时态的制约，一般要遵循以下三条原则： 1．主句是祈使句或主句中的谓语动词是一般现在时或一般将来，则宾语从句根据实际选用时态。如： Will you tell us which places you visited during the vacation? 2．如果主句中的谓语动词是一般过去时，则宾语从句需要使用表示过去的某种时态。如： I knew she had cleaned the classroom already. 3．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，多用一般现在时。如： He said time is money. Our teacher told us that light travels much faster than sound. 宾语从句的“否定转移” 当主句的谓语动词为think, believe等词，且主语为第一人称时，从句中的否定词not应转移到主句谓语动词。如： 合并为一句 宾语从句的简化结构 由特殊疑问词引导的宾语从句通常可以简化成“特殊疑问词＋不定式”结构，此时主从复合句也就变成了简 单句，但简化必须符合以下两种条件： 1．简单句的疑问词为原宾语从句的引导词； 2．原从句的主语应与主句的主语或间接宾语一致。 I don't know what I should do next.(改为简单句) →I don't know ____________________. 含有宾语从句的复合句的反意疑问句 1．陈述部分是“I/We think (know, believe, suppose, consider)＋that从句”或者是“I'm/We're sure that; I'm/We're afraid that; I/We hope that; It seems that”时，附加疑问部分的主语应和从句一致，但需注意否定前移的情况。如： I don't think he is right, ____________？ I'm sure that you know him well, ______________？ 2．如果主语是其他人称，附加疑问部分的主语和主句一致。如： Your father believed you could succeed, ______________？ Kate doesn't know if Jim is a good singer, ______________？ 宾语从句中人称的变化 注意宾语从句中人称代词的正确使用。一般遵循“一随主，二随宾，第三人称不更新”的原则。 解题技巧：
宾语从句基本讲解与练习 宾语从句小口诀 宾语从句三注意，时态语序引导词； 主句一般现在时，从句不需受限制； 主句一般过去时，从句须用相应时； if/whether,引，一般疑问句陈述句转that 特殊问句疑问词，引导词后陈述式。 一、概念宾语作用的从句叫做宾语从句。在句子中起到二、连接词 在从句中不。that在非正式场合that可以省略)1. 陈述句转化成宾语从句时，引导词用that ( 充当任何成分，也没有实在意思，只起到连接作用。没有人告诉杰克第二天有班No one told Jack (that) there would be a class meeting the next day. 会。Little Tom was afraid (that) he couldn't pass the exam. 小汤姆担心这次考试不及格。say, think, wish, hope, imagine, wonder, know, believe, 从句做宾语的动词有：that1】可跟【拓展等。agree, explain, feel, suggest, hear, mean, notice等词，而宾语从句的意思是否定expect think, believe, suppose, 【拓展2】当主句谓语动词是

宾语从句讲解 在复合句中用作宾语的从句叫宾语从句。 1．语序 无论主句是陈述句还是疑问句，宾语从句都必须使用陈述语序，即“主句＋连词＋宾语从句（主语＋谓语＋……）”句式。根据连接词在从句中所担任的不同成分，可分为以下四种：1）连接词＋谓语。连接词在从句中作主语。常见的连接词有：who，what，which等。如：Could you tell me who knows the answer，please？你能告诉我谁知道答案吗？ The small children don't know what is in their stockings．这些小孩子不知道袜子里有什么东西？ 2）连接词＋名词＋谓语。连接词在从句中作主语的定语。常见的连接词有：whose，what，which，how many，how much等。如： He asked whose handwriting was the best in our class．他问我们班上谁的书法最好。 The teacher asked us how many people there were in the room．老师问我们房间里有多少人。3）连接词＋主语＋谓语。连接词在从句中作宾语、状语或表语。常见的连接词有：who（m），what，which，how many，how much，when，why，how，where，if ／whether（在句中不充当任何成分）等。如： He hasn't decided if he'll go on a trip to Wuxi．他还没决定是否去无锡旅行。 Could you tell me what I should do with the money ？你能告诉我我如何处理这笔钱吗？ 4）连接词＋名词＋主语＋谓语。连接词在从句中作宾语或表语的定语。常见的连接词有：what，which，how many，how much，how等。如： Do you know which class he is in ？你知道他在哪个班吗？ She asked me if I knew whose pen it was．她问我是否知道这是谁的钢笔。 2．连接词 1）当由陈述句充当宾语从句时，用that引导，that无词义，在口语或非正式文体中常省略。如： He said that he could finish his work before supper．他说他会在晚饭前完成工作。 2）当由一般疑问句充当宾语从句时，用if或whether引导，意为“是否”。如： I don't know if ／whether he still lives here after so many years．我不知道这么多年后他是否还住在这儿。 但在下列情况下只能用whether： ①在具有选择意义，又有or或or not时，尤其是直接与or not连用时，往往用whether（if…or not也可以使用）。如： Let me know whether ／if he will come or not．（＝Let me know whether or not he will come）让我知道他是否能来。 I don't know whether ／if he does any washing or not．（＝I don't know whether or not he does any washing．）我不知道他洗不洗衣服。 I wonder whether we stay or whether wego．我不知道我们是去还是留。 ②在介词之后用whether。如： I'm interested in whether he likes English．我关心的是他是否喜欢英语。 We're thinking about whether we can finish the work on time．我们正在考虑是否能按时完成这项工作。
