范文一：仁爱初中宾语从句知识点总结
宾语从句
1.宾语:是动作的承受者,一般放在及物动词后面。如,
Our team beat all the others.我们的球队打败了所有其他球队。
2.有时为了强调,宾语也可以放在句首,如,
Two weeks you shall have .你可以有两周的时间。
3.名词作宾语
Face the facts!
4.代词作宾语
They won’t hurt us.
5. 数词作宾语
If you add 5 to 5, you get 10
一、宾语从句的用法,
宾语是句子的一个重要成分,它可以由名词、代词、名词短语或句子充当。当一个句子充当宾语时,这个句子就叫做宾语从句。
二、宾语从句结构,
1、主句+ that，无词义,可省略，+从句，陈述句语序，
2、主句+ whether / if ，是否，+从句，陈述句语序，
3、主句+疑问词+从句，陈述句语序，
三、宾语从句的引导词,
引导宾语从句的引导词按所引导的句子结构特点可以分为三类。
1、that 引导的宾语从句,原句如果是陈述句,变宾语从句时要用 that 引导,that 无实义,只起到引导的作用。在口语和非正式文体中常可省略。
如:
(1)I think (that) I can sell newspapers.
我想我可以卖报纸。
(2) I know (that) he is a Canadian athlete.
我知道他是一名加拿大运动员。
(3) Do you think (that) the children need to write.
你认为孩子们需要写一首歌吗,
(4)Maria says (that) she doesn’t like the uniforms.
玛举亚说她不喜欢校服。
2、whether/if引导的宾语从句,
原句如果是一般疑问句,变宾语从句时要用whether /if 引导,whether /if意为“是否”。 如,
(1)I want to know whether / if people will leave as soon as they finish eating in western countries.
我想知道西方国家的人是否是一吃完饭就离开。
(2)Could you tell me if /whether it’s polite to speak loudly at the table ?
你能不能告诉我吃饭时大声讲话是否有礼貌,
(3) I don’t know if/whether you are right. 我不知道你是否正确。
注意,whether/if 引导的
宾语从句用法区别,用whether /if “是否”引导的宾语从句,通常情况下whether /if 可以互换。但以下情况 whether 不能 用if 换。
(1) Whether后面紧跟有or not时。如,
I don’t know whether or not it rains.
我不知道是否会下雨。
(2) whether 引导主语从句位于句首首时。如,
Whether they will go by air or by train hasn’t decided.
他们是乘飞机去还是乘火车去还没有定下来。
(3) whether 用在带有to的动词不定式之前。如,
Please tell us whether to go or stay. 请告诉我们是去还是留。
(4) 有些动词 (如,discuss) 后面只能跟whether,不能跟if。 如,
We discussed whether we should let him join our team. 我们商量是否让他加入我们队。
(5) whether 可以与虚词it连用,并可引导不定式,但if 不能这样用。 如,
It’s not clear whether he will be able to come。
他是否会来还不清楚
3、疑问词引导的宾语从句,原句如果是特殊疑问句,变宾语从句时要用特殊疑问词引导。疑问词包括疑问代词，what, which, who, whose) 和疑问副词，when, how, where, why)。 如,
1、 Do you know who that man is over there ?
你知道那边那个人是谁吗,
2、You may ask what North American people wear on special days.
你也许会问北美洲的人在特殊的日 子里穿什么衣服。
3、I ask Tom which Chinese dish is his favorite.
我问汤姆他最喜欢的是那一道中国菜。
4、I don’t know who will come to the English corner.
我不知道谁会来英语角。
5、 Can you tell me how you deal with the problem ?
你能告诉我你怎样解决这个问题吗,
6、Can you tell me where they are ?
你能告诉我他们在哪里吗 ?
7、I ask him why his hot dogs are so popular.
我问他为什么他的热狗这么受欢迎。
四. 宾语从句的语序,宾语从句的语序一定要使用陈述句语序。
1.一般疑问句改成宾语从句时,先在从句前加上if/whether,然后把它变成陈述句序即可,当然也要注意时态的变化和some,陈述句用some,/any,否定用any,的变化. 如,Can you play football? ? I don't know if/whether you can play football. 2.陈述句改成宾语从句时,先在从句前加上that,也可以不加,,照抄即可,当然也要注意时态的变化. 如,She is a student.
? He said (that) she was a student. 3.特殊疑问句改成宾语从句时,疑问词不变依然放在从句句首,其后变成陈述句序,当然也要注意时态等变化. 如,How old is he?
? I wanted to know how old he was.
五、 宾语从句主句与从句时态一致的问题,主句若是一般现在时,从句可根据句意内容使用各种时态,主句如果是一般过去时,从句只能用相应的过去时态。如果宾语从句所陈述的是客观真理、自然现象或定理等,则只能用一般现在时。
如,
1、I think ，that，you are right.
我认为你是对的。
、I thought ，that， he watched the match. 2
我想他看过比赛了。
3、He told me ，that， he studied very hard.
他告诉我他学习非常努力。
4、He said ，that， Bill would go there soon.
他说比尔不久就将去那里。
5、The teacher said (that) the earth goes around the sun.
老师说地球绕着太阳转。
6、I want to know whether / if it is polite to point at people with chopsticks in China.
7、He asked me whether / if it was impolite to eat one’s soup very noisily in most African countries. 8、My little brother asked me whether / if the earth goes around the sun.
六. 宾语从句口诀,
宾语从句三注意,时态、语序、引导词。
主句若是过去时,主从时态要一致。
宾从表达是真理,一般现在就可以。
引导词也不难,陈述可用that连。
一般问句表“是否”,if或whether来引导。
特殊问句作宾从,疑问词引导就能行。
还有一点要说明,陈述语序要记清。

范文二：宾语从句知识点
宾语从句
1. 宾语从句：在句中作宾语，由连词连接主句和从句，下列句中划线部分是宾语从句
例：He didn’t know . 他不知道那个男人是谁？
宾语从句（who 是连接词）
2. 限制宾语从句的连接词有三点
①宾语从句是陈述句意思，用that 作连词，that 可以省略
例：He said . 他说他正在等一辆公共汽车。 ②宾语从句是一般疑问句的意思，则用if 和whether 作连词
例：I don’t know . 我不知道是否他将会来？ ③宾语从句是特殊疑问句的意思，用疑问词作连词
例：I don’t know . 我不知道他将买什么？（what 作连词）
Jim knew Jim 知道他们邀请了多少人。(how many people
作连词）
3. 限制宾语从句的语序只有一点：宾语从句中，主语要在前，谓语在后
例：Do you know whose watch ? 你知道是谁的手表吗？ （主语it 在前，谓语is 在后）
你知道是谁正在房间里读书吗？（主语who 在前，谓语
is reading在后）
4. 限制宾语从句的时态有2点
①如果主句是过去时态，则从句只能用过去的时态（一般过去时，过去进行时，过去将来时，过去完成时，都是过去的时态）
例：The teacher wanted to know 语从句是一般过去时）
老师想知道，吉姆昨天为什么迟到了。
. （宾语从句是过去完成时）
他说他已经买了一本书。
②如果宾语从句指的是客观真理，格言，解释科技内容或强调现在的事实，必须用一般现在时
例：He knew（太阳在东边升起是客观真理，宾语从句用一般现在时）
他原来就知道太阳从东边升起。
5. 下列三个划线的句子意思相同，在宾语从句中，语序不变
例：I don’t know ? 我不知道Jim 有什么不舒服？ = I don’t know
= I don’t know 6. if 和whether 的意思相同，表示“是否”：下列情况只用whether ，不用if ①放在不定式前 例：Please tell us 请告诉我们是走还是留。
②句中有or 或or not时 例：I wonder I’ll catch the last bus 我想知道是否我会赶上最后一班公共汽
车。
7. 感叹句如何放在宾语从句中

南京伟卓教育培训中心
初 中 宾 语 从 句
一：宾语从句的意义及结构
语法意义：宾语从句属于名词性从句，
在复合句中作主句的宾语。
宾语从句由从属连词(that, whether, if)
连接代词(which, what, who, whose, whom)
连接副词(where, how, when, why)等引导。 及物动词、介词或某些形容词后可带宾语从句。
eg. We know Mr Green teaches English.
She asked if these answers were right.
句型结构：主语+谓语+引导词+主语+谓语(+其他成分)
一：宾语从句的引导词
(1) 陈述句作宾语（作从句的原句是陈述句）从句引导词用that。that在从句中不充当任何句子成分，无实际意思，在口语或非正式文体中常省略。
如： He said (that) it was cold in Moscow.
Mother knows (that) Jim will work hard.
(2) 一般疑问句作宾语从句引导词用whether或if。 whether或if表示“是否、是不是”的意思，不能省略。原句为一般疑问句，选择疑问句或反意疑问句。常用在ask, wonder, can(could) you tell me 等后。如：
I want to know if / whether the answer is right.
Lucy asked if / whether they had a cheaper shirt.
(3) 特殊疑问句作宾语从句引导词用原来的疑问词，只不过在宾语从句中称作连接代词或连接副词。连接代词或连接副词在从句中充当一定的句子成分，有一定的意思，不能省略。如：
Please tell him which class you are in.
Could you tell me where the post office is?
Please ask the teacher how we can get there.
南京伟卓教育培训中心
宾语从句语序：在复合句中，宾语从句部分要用陈述语序。
(1) 陈述句作由that引导的宾语从句时，语序不用调整。
(2) 一般疑问句作宾语从句时，其结构为whether / if +陈述句。原一般疑问句的主语前如果是助动词do / does / did，应去掉，谓语动词应改为其相应的形式;原一般疑问句的主语前如果是don’t / doesn’t / didn’t，则直接将其放到主语之后;原一般疑问句的主语前如果是be 动词、情态动词或其他助动词，则应将其放到主语之后。如：
Does he like apples? I don’t know.-I don’t know whether he likes apples. He asks: Is Tom a diver? -He asks whether Tom is a driver.
(3) 特殊疑问句作宾语从句时， 如果疑问词作主语或主语的定语，其语序不用变化;如果疑问词充当其他句子成分，则宾语从句的结构为连接代词 / 连接副词+陈述句。如：
Who can answer the question? I want to know.
-I want to know who can answer the question.
宾语从句中的时态
1.如果主句的时态是一般现在时或一般将来时或祈使句时，从句的时态则根据具体情况或具体意义来确定。如：
① I don't know when he came back.
② Do you know where they will go this summer holiday?
③He is worried about whether he has passed the English exam.
④ Please tell us what we should do next, OK?
⑤ Will you please tell me how I can get to the post office?
2.如果主句的时态是一般过去时，从句的时态则相应地使用一般过去时/过去将来时/过去完成时/过去进行时等。如：
① He said that he didn't find your lost pen.
② My parents told me that they would go to Beijing.
③ The policeman asked him what he was doing at midnight yesterday. ④ I told you yesterday that I had returned your book. Why do you ask for it again?
南京伟卓教育培训中心
3.如果宾语从句所叙述的是客观真理、自然现象、名言警句或谚语等，不管主句是什么时态，从句都用原时态。如：
① Our geography teacher told us that the earth goes around the sun. ② When I was young, my father often told me that knowledge is power . ? 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：
I don’t know whether to go.
3.当与or not连用，或提出两种选择时:
Mary asked whether I was doing my homework or not.
Tell me whether you’d like to go shopping or tidy the room.
4.Whether置于句首时，不能换用if
Whether this is true or not,I can’t say.
5.引导主语从句和表语从句时，宜用whether
The question is whether we can catch the bus.
哪些宾语从句不可以省略引导词that
当that做learn, suggest,explain,agree,wonder,prove,mean,state, feel,hold等动词的宾语时;
当宾语从句较长时;
当主语状语置于主句尾,宾语从句之前时;
当主语谓语动词(包括非谓语动词)与宾语从句之间有插入语时;
当一个动词带有两个或两个以上宾语从句时,此时第一个that可以省略,第二个that不可以省略;
当宾语从句中的主语是this,that或this,that做主语的定语时;
当宾语从句是双宾语中的直接宾语时;
当宾语从句的主语是非谓语动词或主语从句时;
当主语中的谓语动词是固定词组时;
当宾语从句有it做其先行词时;
在直接引语中,转述分句把宾语从句隔开时.
南京伟卓教育培训中心
从句中人称与标点的变化
1.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.
2.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?
初中宾语从句知识点：宾语从句的简化
1. 当主句谓语动词是find，see，watch，hear等感官动词时，从句常简化为“宾语+宾补”结构，宾补为不带to的不定式或V-ing形式。如：
She found that the wallet lay/was lying on the ground.
→She found the wallet lie/lying on the ground.
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.
3. 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”结构。如：
Can you tell me how I can get to the station?→Can you tell me how to get to the station?
南京伟卓教育培训中心
语法口诀：宾语从句。
宾语从句须注意，几点事项应牢记。
一是关键引导词，不同句子词相异。
陈述句子用that;一般疑问是否(if，whether)替;
特殊问句更好办，引导还用疑问词。
二是时态常变化，主句不同从句异。
主句若为现在时，从句时态应看意;
主句若为过去时，从句时态向前移。
三是语序要记清，从句永保陈述序。
【妙语诠释】宾语从句应注意三点：①引导词，陈述句一般由that引导，这时的that可以省略;一般疑问句则由if或whe-ther引导;而特殊疑问句则由特殊疑问词引导。②时态，主句是现在时态，从句可用所需要的任何时态;但如果主句是过去时态，从句时态所表示时间一般往前移一个时间段。③语序，宾语从句永远要用陈述句顺序。
范文四：宾语从句知识点
宾语从句
1. 宾语从句引入：
1She told me something. ○
2She told me that the film was really good. ○
1
Our success depends on hard work. ○
2. Our success depends on whether we work hard.
1I’m afraid that’s impossible. ○
这种表示心理状态的词，（afraid ,sorry ,sure, glad, worried等）在句子中
作表语时，后面可以接宾语从句
2. 对宾语从句的考查主要集中在以下几个方面：
(1)宾语从句的连接词的选择
(2)宾语从句的语序
(3)宾语从句的时态
（4）宾语从句的其他注意点
(1) 引导宾语从句的词
that
whether 和 if
what , which ,who ,whom ,whose—连接代词
when ,where, how ,why—连接副词
1that ○
that——没意思，不作成分（在口语和非正式文体中可以省略）
He said (that) he wanted to stay at home.
I am sure (that) he will succeed.
2 If和whether在句中的意思：“是否” ○
I want to know if (whether) he lives there.
He asked me whether (if) I could help him.
☆ 用whether，不用if：
1.介词后面的宾语从句
Our success depends on whether we work hard.
2. 与or或or not连用
I don’t know whether it will rain tomorrow or not.
(了解)3. whether可以引导带to的不定式。如：
I don’t know whether to accept or refuse. I don’t know if to accept or refuse.
3由连接代词who, whom, whose, what, which和连接副词when, where, why, ○
how引导的宾语从句
这些连接代词和连接副词在宾语从句中充当某个成分
Do you know who (whom) they are waiting for?
I don’t know whose bag that is.
I don’t know how I can improve my English.
☆由how构成的词组也可以引导宾语从句的，如how old, how many ,how
much ,how often ,how long ,how far 等等
Can you tell me how old he is.
（2）宾语从句的语序
宾语从句的语序应为陈述句的语序
I hear (that) physics isn’t easy.
你知道咱多会儿放假吗？
Do you know…..
When will we have the holiday?
Do you know when we will have the holiday.
Can you tell me where I can buy the dictionary.
（3）宾语从句的时态
1 如果主句的时态是一般现在时，宾语从句根据表达的意思，该用什么 ○
时态就用什么时态—主现从随
我记得他去年给了我一本字典。
1（河北 2011）（）25. ——Do you know________?
——They moved here soon after their son was born.
A. when would the Greens move here
B. when the Greens moved here
C. the Greens would move here
D. when the Greens would move here
答案：D
2.（山东济宁 2011）25. Can you tell me ______ after this exam ?
A. what you did B. what did you do
C. what will you do D. what you will do
答案：D
3. （呼市 2006）13. The students said they ____ have a picnic together
after the big test.
A. would love to B. would love
C. had love to D. had love
答案：A
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）
He said… 他昨天去博物馆了——————一般过去
他昨天晚上9:00正在打电话——过去进行
他将要去趟三亚———————过去将来
——————过去完成
He asked what time it was.
He told me that he was preparing for the sports meeting.
3如果宾语从句所陈述的是客观真理，其时态常用一般现在时。例如： ○
Our teacher said that January is the first month of the year.
Scientists have proved that the earth turns around the sun.
（4）宾语从句的其他问题
1if和when既能引导时间状语从句，又能引导宾语从句 ○
If it rains tomorrow，I won’t come.
（条件状语从句）if表示“如果，要是”
I don’t know if it will rain tomorrow.
（宾语从句）if表示“是否
（呼市 2010）6. l don't know ____ he will come tomorrow ,___ he comes,
I'll tell you.
A. if; Whether B whether; Whether
C. if; That D. if: If
答案：D
2从句的简化 ○
Can you tell me how I can get to the station？ →Can you tell me how to get to the station？
She doesn’t know what she can do.
She doesn’t know what to do.
【1】 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”结构
练习：
1.He asked us how he can mend the recorder.
2.He asked us how to mend the recorder.
最常见的结构：
Can you tell me+what/when/how/… I …
He doesn’t know what/how/where/…he…
3宾语从句的否定转移 ○
主句的主语是第一人称，谓语是think ,believe ,suppose等词时，将从句的否定词转移到主句中
我认为他不会跟你去。
I don’t think he will come with you.
4 我发现学好英语很难。 （了解）○
I find it difficult to learn English well.

用变化;如果疑问词充当其他句子成分，则宾语从句的结构为连接代词 / 连接副
词+陈述句。如:
Who can answer the question? I want to know.

南京伟卓教育培训中心 从句中人称与标点的变化
1.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. 2.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? 初中宾语从句知识点:宾语从句的简化
1. 当主句谓语动词是find，see，watch，hear等感官动词时，从句常简化
为“宾语+宾补”结构，宾补为不带to的不定式或V-ing形式。如:
She found that the wallet lay/was lying on the ground.
?She found the wallet lie/lying on the ground.
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.
3. 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”结构。如:
Can you tell me how I can get to the station??Can you tell me how to get to the station?

语法口诀:宾语从句。
宾语从句须注意，几点事项应牢记。
一是关键引导词，不同句子词相异。
陈述句子用that;一般疑问是否(if，whether)替;
特殊问句更好办，引导还用疑问词。
二是时态常变化，主句不同从句异。
主句若为现在时，从句时态应看意;
主句若为过去时，从句时态向前移。
三是语序要记清，从句永保陈述序。
【妙语诠释】宾语从句应注意三点:?引导词，陈述句一般由that引导，这时的that可以省略;一般疑问句则由if或whe-ther引导;而特殊疑问句则由特殊疑问词引导。?时态，主句是现在时态，从句可用所需要的任何时态;但如果主句是过去时态，从句时态所表示时间一般往前移一个时间段。?语序，宾语从句永远要用陈述句顺序。
