在英语中,主要有三大从句,即名词性从句(包括主语从句,宾语从句,表语从句,同位语从句)、形容词性从句(即定语从句)、副词性从句(即状语从句,包括时间、条件、结果、目的、原因、让步、地点、方式等)。
一、定语从句概念定语从句(attributive clause),顾名思义,就是一个句子作定语从属于主句。
定语一般是由形容词充当,所以定语从句又称作形容词从句。
另外,定语从句是由关系代词或关系副词引导的,故又称作关系从句。
定语从句一般放在它所修饰的名词或代词之后,这种名词或代词被称作先行词。
请看示例:The woman who lives next door is a teacher. (先行词)二、关系代词引导的定语从句关系代词代替前面的先行词,并且在定语从句中充当句子成分,可以作主语、宾语、定语等。
常见的关系代词有:who, that, which。
它们的主格、宾格和所有格如下表所示:(一)关系代词who, whom和whose的用法who代替人,是主格,在定语从句中作主语。
例如:An architect is a person who designs buildings. 建筑师是设计房屋的人。
whose一般代替人,有时亦可代替物,是所有格,在定语从句作定语。
例如:The girl student whose father is a senior engineer used to study abroad. 其父是一位高级工程师的那个女学生过去在国外留学。
(二)关系代词which的用法which代替物,在定语从句作主语或宾语,作宾语时还可省略。
例如:I do not like stories which have unhappy endings.我不喜欢有不幸结局的小说。
(which可以换成that)(三)关系代词that的用法that既可指人又可指物,在当代英语中大多指物,在定语从句作主语或宾语,作宾语时还可省略。

根据引导宾语从句得不同连词,宾语从句可分为三类。
1. 由that引导得宾语从句。
that只有语法作用,没有实在得意义,在口语与非正式文体中可以省略、例如:He said (that) he wanted to stayat home。
She doesn’tknow (that)she is seriously ill.I am sure(that)hewill succeed。
2。
由连接代词who,whom, whose,what, which与连接副词when, where,why,how引导得宾语从句。
这些连接代词与连接副词在宾语从句中充当某个成分。
例如:ﻫDoyouknowwho (whom) theyare waiting for?He asked whosehandwritingwas thebest、Can you tell me wherethe No.3busstopis?Idon't know why the train islate。
3。
由if或whether引导得宾语从句。
if与whether在句中得意思就是“就是否”。
例如:ﻫI want toknow if (whether) helives there.ﻫHe asked me whether(if)Icould help him、ﻫ(二)宾语从句得语序宾语从句得语序应为陈述句得语序。
例如:ﻫIhear (that) physicsisn’t easy、ﻫI think (that) you willlike this school soon、ﻫCan yo utellme howIcanget to zoo?ﻫPleasetell mewhenwe’ll have the meeting。
(三)宾语从句得时态1ﻫ。
初中英语中考复习:三大从句(含答案))三大从句精讲点拨宾语从句1).概念:用一个完整的句子做宾语,叫做宾语从句。
宾语从句可作主句谓语动词的宾语,也可做介词的宾语。
宾语引导词打酱油派(无意义无成分that可省略)if/whether 纠结派(yes or no )个性派(看具体情况选He said (that) he could finish his work before supper.Alice wanted to know if / whether her grandmother liked the bag.I don’t know where I can buy the books.特殊疑问词从句语序陈述语序用)“引导词 +主语 +谓语 +其I want to know what you were doing at that time.时态它”主过从过,主现从任 I believe that he will come to help us.He knew that he was wrong.2).易错点:1.引导词 if 不能与 or not 连用;whether 可以。
如:I don’t know whether I can pass the exam or not .2. could 开头的一般疑问句代表委婉请求,不代表过去式。
如:Could you tell me how I can go to the bus station?3. 从句为客观真理时,时态不受主句影响。
(注意三单哦!如:The teacher told us yesterday that the earth g oes round the sun.4. 当从句为What’s the matter ?或What’s wrong 时,从句的语序不用改变。
★拓展:宾语从句的简化由特殊疑问词引导的宾语从句,若从句的主语在主句中出现过时,可简化为“疑问词+不定式”结构。

例如:Do you know who (whom) they are waiting forHe asked whose handwriting was the best.Can you tell me where the bus stop is?I don’t know why the train i s late.3. 由if或whether引导的宾语从句。
if和whether在句中的意思是“是否”。
例如:I want to know if (whether) he lives there.He asked me whether (if) I could help him.(二)宾语从句的语序宾语从句的语序应为陈述句的语序。

中考英语语法复习:三大从句三大从句一、知识要点1.宾语从句:在句子中起宾语作用的从句叫宾语从句,知识点有三个:引导词、语序和时态。
引导词有三种:①that;②whether/ if;③特殊疑问词What/ when/ where/ who等。
He said that he could help me.他说他能够帮助我。
Your mother asked if you could finish your work this week.你妈妈问这个星期你能否完成工作。
Can you tell me when the sports meeting will begin?你能告诉我运动会将在什么时候开始吗?①以that引导的宾语从句:that引导的宾语从句一般都是由陈述句充当,引导词that没有实际意义,不在从句中作任何成分,that可以省略,而且从句成分齐全,句意完整。
Do you think (that) it will rain?你认为天会下雨吗?He said (that) he could come on time.他说他会准时来的。
②以whether或if引导的宾语从句:从属连词if, whether引导的名词从句是由一般疑问句或选择疑问转化而来的,变成从句后,语序由原来的倒装语序变成陈述语序。
whether和if意思是“是否”。
Let us know whether / if you can finish the work before Friday.请让我们知道你是否能在星期五以前把工作做完。
I don’t care whether you like the story or not.我不在乎你是否喜欢这个故事。
注意:以下情况一般只用whether不用if。
①接带to的动词不定式。
She doesn’t know whether to go to the zoo.她不知道是不是去动物园。
初三英语语法串讲从句的分类与用法在初三英语的学习中,从句是一个重要且复杂的语法知识点。
掌握从句的分类与用法对于提高英语语言能力和应对考试都具有关键作用。
接下来,让我们一起深入了解一下从句的世界。
从句,简单来说,就是一个句子在另一个句子中充当某个成分。
根据其在主句中所充当的成分,从句可以分为三大类:名词性从句、形容词性从句(定语从句)和副词性从句(状语从句)。
一、名词性从句名词性从句包括主语从句、宾语从句、表语从句和同位语从句。
1、主语从句主语从句在句子中充当主语,通常放在句首。
例如:“What he saidis true”(他说的是真的。
)在这个句子中,“What he said”就是主语从句。
需要注意的是,为了避免句子头重脚轻,有时会用 it 作形式主语,而把真正的主语从句放在后面。
比如:“It is clear that he is wrong”(很明显他错了。
)2、宾语从句宾语从句在句子中充当宾语,常跟在及物动词、介词或某些形容词后面。
例如:“I believe that he is honest”(我相信他是诚实的。
)“We are interested in what you said”(我们对你所说的感兴趣。
)宾语从句的语序要用陈述句语序,即“主语+谓语+其他”。
同时,要注意宾语从句的时态,要根据主句的时态来变化。
3、表语从句表语从句在句子中充当表语,位于系动词之后。
例如:“The problem is whether we can finish the work on time”(问题是我们能否按时完成工作。
)4、同位语从句同位语从句用于解释说明前面的名词的具体内容。
常见的名词有:fact, news, idea, thought, hope 等。
例如:“The news that he will come is true”(他要来的消息是真的。
)二、形容词性从句(定语从句)定语从句在句中起定语作用,修饰一个名词或代词。
中考英语语法——三大从句(宾语从句、定语从句、状语从句):一、宾语从句宾语从句在句子中作为宾语,通常放在动词、介词或形容词后面。
三大考点:引导词、时态和语序。
其中,语序必须是陈述句语序。
1. 常由下面的一些词引导:●由that 引导,表示陈述意义,that可省略。
●由if ,whether 引导,表示一般疑问意义(带有是否、已否、对否等)。
●由连接代词、连接副词(疑问词)引导,表示特殊疑问意义。
2. 时态:主句用现在时或将来时,从句可用任何时态。
主句用过去时,从句用与过去相关的时态。
(1)从句说明的是一般真理、客观事实、自然现象、名言时,仍用现在时。
(2)从句中有具体时间状语,即使从句动作发生在主句动作前,仍用一般过去时。
【例】主句:I don't know.(我不知道。
)从句:if he will come.(他是否会来。
)解释:在这个例子中,“他是否会来”是宾语从句,作为“不知道”的宾语。
英文中,“if he will come”也起到了同样的作用,作为“don't know”的宾语。
二、定语从句定语从句在句中作定语,修饰一个名词或代词,被修饰的名词、词组或代词即先行词。
定语从句通常出现在先行词之后,由关系词(关系代词或关系副词)引出。
关系代词:who,whom,whose,that,which。
关系副词有:where,when,why。
【例】主句:I like the book.(我喜欢那本书。
)从句:that is red.(那本红色的。
)解释:在这个例子中,“那本红色的”是定语从句,修饰名词“书”。
英文中,“that is red”是定语从句,修饰名词“book”。
三、状语从句状语从句在复合句中作状语,修饰主句中的动词、形容词或副词等。
状语从句放在主句前时,常用逗号隔开;放在主句后时,可以不用逗号;放在主句中间时,从句前后都要用逗号。
状语从句根据意义可分为时间状语从句、地点状语从句、原因状语从句、目的状语从句、结果状语从句、条件状语从句、让步状语从句、比较状语从句和方式状语从句。
在初中英语中,主要有三大从句,即宾语从句、定语从句、状语从句(包括时间、条件、结果、目的、原因、让步、地点、方式等)。

1宾语从句在句子中起宾语作用的从句叫做宾语从句。
that: I think that you can pass the exam.Whether/if: I don’t know what the word means.“Wh”: I don’t know what the word means.I don’t know where he found the book.只用whether的情况:1. 与or not连用:I don’t know whether it’s raining or not.2. 与动词不定式连用:He doesn’t know whether to accept the invitation.3. 连接词前有介词时:It depends on whether he is coming.1. 主句是一般现在时态,从句根据实际情况而定(各种时态均可)She wants to know what he has done for the exam.2.主句是一般过去时态,从句用相应的过去的时态。
1)She said that she was a student.2)She said that she would fly to Japan in a week.3)She said that she had finished her homework already.3. 如果宾语从句说的是客观真理、自然现象或事实时,这时宾语从句要用一般现在时态。
The teacher said that the earth goes round the sun.2定语从句在复合句中修饰名词、代词的从句叫定语从句。

中考英语三大从句知识点总结精品|初中三大从句总结:定语从句精讲,必须收藏!定义在主句中做宾语的从句叫做宾语从句。
(简单来讲,就是用一个句子充当了另一个句子的宾语)如:She knew that the teacher had seen the film.“that the teacher had seen the film”做knew 的宾语,同时又是由连接词that 引导的从句,所以它叫做宾语从句。
分类1.动词宾语从句:顾名思义,它是位于动词后面的宾语从句。
He asked whose handwriting was the best in our class.他问我们班上谁的书法。
2.介词宾语从句:顾名思义,它是位于介词后面的宾语从句。
I agree with what you said just now.我同意你刚才说的话。
3.形容词宾语从句:顾名思义,它是位于形容词后面的宾语从句。
I am afraid that I will be late.恐怕我要迟到了。
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。
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。
He asked whose handwriting was the best in our class.他问我们班上谁的书法。
初中三大从句一、中考要求:宾语从句、定语从句、状语从句的用法是中考热点之一,主要考查三种从句的引导词的选择;宾语从句的语序和时态;状语从句主要考查时间状语从句、条件状语从句、因果状语从句,特别是条件状语从句的时态、so… that引导的结果状语从句和目的状语从句等。
二、知识要点:1. 宾语从句:在句子中起宾语作用的从句叫宾语从句,中考主要考查的知识点有三个:引导词、语序和时态。
宾语从句的引导词有三种:1)that;2)whether/ if;3)特殊疑问词What/ when/ where/ who等。
例如:He said that he could help me. 他说他能够帮助我。
Your mother asked if you could finish your work this week.你妈妈问这个星期你能否完成工作。
Can you tell me when the sports meeting will begin?你能告诉我运动会将在什么时候开始吗?1) 以that引导的宾语从句:that引导的宾语从句一般都是由陈述句充当,引导词that没有实际意义,不在从句中作任何成分,that可以省略,而且从句成分齐全,句意完整。
Do you think (that) it will rain? 你认为天会下雨吗?He said (that) he could come on time. 他说他会准时来的。
2) 以whether或if引导的宾语从句:从属连词if, whether引导的名词从句是由一般疑问句或选择疑问转化而来的,变成从句后,语序由原来的倒装语序变成陈述语序。
whether和if意思是“是否”。
Let us know whether / if you can finish the work before Friday.请让我们知道你是否能在星期五以前把工作做完。
I don’t care whether you like the story or not. 我不在乎你是否喜欢这个故事。
注意:以下情况一般只用whether不用if。
①接带to的动词不定式。
She doesn’t know whether to go to the zoo. 她不知道是不是去动物园。
②与or not连用时。
I’m not sure whether or not he will come on time. 他能否准时来,我说不准。
3) 含疑问意义的连接词引导的宾语从句:此类宾语从句原来是特殊疑问句,变成宾语从句后要用陈述语序,由wh-1开头的疑问词引导。
wh-词包括who, whom, whose, what, which等连接代词和where, when, how, why 等连接副词,这些引导词有各自的意思,在从句中要作相应的成分,不能省略。
例如:Could you tell me which gate we have to go to? 请问我们得走哪个门?He didn’t tell me how long he would stay here. 他没有告诉我他要在这里呆多长时间。
注意:what引导宾语从句时有两种含义,一是“什么”,一是“……的东西/ 事情等”。
例如:In one’s own home one can do what one likes. 在自己家里可以随心所欲。
(what意思为“……的事情”)Can you tell me what we can do for you?请问我们能为你做点什么?(what意思为“什么”)宾语从句的三个注意事项:1)语序:由whether/ if和疑问词引导的宾语从句要用陈述语序,原来的倒装语序改成陈述语序时注意相应的助动词和动词的变化等。
例如:把这两个简单句合成一个复合句:Where does your father work? Can you tell us? ─→Can you tell us where your father works? 你能告诉我们你爸爸在哪里工作吗?Did you get home very late? He asked me. ─→He asked me if I got home very late. 他问我是否到家很晚。
2)时态对应:如果主句是一般现在时,宾语从句根据实际情况用各种时态。
例如:My teacher says he will be back in a week. 我的老师说他将在一个星期后回来。
(一般将来时)My teacher says he is watching TV. 我的老师说他正在看电视。
(现在进行时)My teacher says he has seen the movie. 我的老师说他已经看过这部电影了。
(现在完成时)如果主句是一般过去时,宾语从句用相应的过去时态。
例如:My father said he was watching TV at that time. 我爸爸说在那个时候他在看电视。
(过去进行时)My father said the he had already seen the movie. 我爸爸说他已经看过那部电影了。
(过去完成时)2如果宾语从句是表示客观真理和规律的句子时,用一般现在时。
例如:Our teacher told us the sun is much bigger than the earth.我们的老师告诉我们太阳比地球大多了。
(一般现在时)3) 否定转移:主句如果是I think/ believe/ imagine/ suppose/ guess/ expect等,从句的否定一般要转移到主句中,其反意疑问句与从句一致。
例如:I don’t think they’ll wait to the last minute. 我认为他们不会等到最后一分钟。
I don’t believe he did this, did he? 我相信他不会做这样的事,他会吗?宾语从句专项练习题1.I don't know ____ next.A.how to doB.what to do itC.what I should doD.how I should do2.Can you tell me ____?A.who is that manB.who that man isC.that man is whoD.whom is that man3.He ____ in the English exam.A.believes that he can't failB.believes that he couldn't failC.doesn't believe he shouldn't failD.doesn't believe he has failed4.I want to know ____.A.what is his nameB.what's his nameC.that his name isD.what his name is5.Please tell us ____,will you?A.when the plane will leaveB.when will the plane leaveC.when does the planes leaveD.when the plane leave6.I'll write down ____.A.how you can do itB.how to doC.how can you do itD.how do you do it7.Could you please tell me ____?A.which gate have we to go toB.which we go to gateC.which gate we have to go toD.which gate we shall go8.They can't explain ____ the fish and the trees around the lake ____.A.that,are diedB.why,are deadC.why,dieD.whether,has been dead9.I didn't know that he ____ to London next week.A.will flyB.would flewC.would flyD.flew10.He asked me ____.A.if I could go with himB.whether could I go with him3C.that I can go with himD.what place I can go with him11.
