英语语法 宾语从句讲解

英语语法宾语从句讲解宾语从句在复合句中做主句的宾语,通俗的说就是一个句子做另一个句子的宾语. 如:I think you are a good student. 动词后面的句子是宾语从句,做主语谓语动词的宾语。
判断方法:1〃可以从整个句式看,宾语从句只能放在主句谓语动词之后。
2〃从引导词看。
if充当宾语从句的连接词时,相当于whether,词义为“是否”,when充当宾语从句的连接词时,意为“什么时候”。
3〃从时态看。
if和when作连接词时,引导宾语从句要注意:从句的谓语动词的时态应根据主句的时态作相应的变化。
学习宾语从句的4个注意事项: 1.连接词宾语从句通常由that, if, whether 和连接代词what, which, who, whom及连接副词when, where ,how, why等连接.其中that 连接一个陈述句做宾语,在中语中that可以省略;除that以外的连接词连接一个一般疑问句做宾语,且疑问句语序改为陈述句〃连接代词及连接副词其实就是特殊疑问句的疑问代词和疑问副词,连接一个特殊疑问句做宾语,语序改为陈述句〃She knows (that) she should study hard.她知道她应该努力学习. He asked me if he could come in.他问我他是否能进来. Can you tell me which class you are in? 你能告诉我,你在哪个班吗? 2.时态一致(即主句的时态与从句的时态相一致) <1>宾语从句中如果主句是现在的时态,从句的时态可根据实际情况而定. I know he lives in Xi'an 我知道他住在西安I know he lived in Xi'an several years ago.我知道他几年前住在西安. I know he has lived in Xi'an for ten years. 我知道他住在西安有十年了. <2>宾语从句中如果主句是过去的时态,那么从句的时态一定要用相应的过去进态.即: 一般现在时----- 一般过去时一般将来时----- 过去将来时现在进行时---- 过去进行时现在完成时---- 进去完成时 3.语序的变化凡宾语从句都必须是陈述句主语序,这一点非常很重要.<1> 陈述句; Lin Tao is a clever man. 宾语从句:He said that Lin Tao was a clever man. <2> 一般疑问句:Does he go home every day? 宾语从句:I wonder if / whether he goes home every day. <3>特殊疑问句:What did she want to do? 宾语从句:I don't know what she wanted to do. 4.人称,地点,时间等的变化在进行句型转换和合并句子的训练中,有些人称,地点状语,时间状语要根据主句做相应的变化〃<1> I will eat as much as I can,Polly says. Polly says that she will eat as much as she can. <2> I've lived here since I was 3 years old, Mike says. Mike says that he has lived there since he was 3 years old. <3>Lin Tao is singing now,he told me . He told me that Lin Tao was singing at that moment.that引导的宾语从句无敌英语语法一、什么是宾语从句?宾语从句是英语中用来充当宾语的句子。

一、英语宾语从句的定义和作用宾语从句是英语复合句子中的一种从句,它作为主句的宾语出现。
宾语从句通常由一个连词(如that, whether 等)引导,或者在某些情况下可以省略连词。
宾语从句的主要作用是作为主句动词的宾语,补充说明主句的意思。
二、英语宾语从句的构成宾语从句的构成包括引导词、主语、谓语、宾语和修饰成分等。
引导词有that, whether, if 等,它们用来引导从句并连接主句。
主语、谓语和宾语则是构成从句的基本成分,通常由名词、动词和代词等词性充当。
此外,宾语从句还可以有修饰成分,如定语、状语等。
三、英语宾语从句的举例及用法以下是一些宾语从句的例子,以帮助读者更好地理解其用法:1.我不知道他会不会来。

(She told me that she likes this movie.)3.他的问题是关于这个项目的。
(His question is about this project.)四、英语宾语从句的注意事项在使用宾语从句时,需要注意以下几点:1.引导词的选择:根据主句的语境和需要,选择合适的引导词,如that, whether, if 等。
2.引导词的位置:引导词在宾语从句中只起连接作用,没有实际意义,因此通常放在从句句首。
3.从句的语序:宾语从句的语序应保持主谓宾的顺序,即使引导词是作宾语,也不例外。
总之,英语宾语从句是英语语法中一个重要的组成部分,掌握好它的构成和用法,对于提高英语写作和阅读能力具有重要意义。

宾语从句讲解
一、概念
宾语从句的宾语部分中有一个从句充当宾语。
二、可接宾语从句的动词
say 、tell 、think、 know、 see、 hear、 hope、 guess、 find、 feel 等,或由形容词构成的系表结构,如:afraid、 sure、 glad、 sorry等
三、宾语从句的标点符号。
宾语从句的标点符号取决于主句,如果主句是陈述句,句尾用句号;如果主句是疑问句,句尾用问号。
四、引导词。
1、that (从句是陈述句时,引导词用that ,它本身无词义,不充当成分,在口语中可省略,但在正式场合不可省。
)
2、if或whether (从句是一般疑问句时用if 或whether ,含义是“是否”。
)
if、whether 一般情况下可以互换,但在构成whether…or not 句式只用whether
3、连接代词、连接副词(从句是特殊疑问句时用)
连接代词(what、 which、 who、 whose )
连接副词(when、 where、 how 、why )
五、宾语从句的同义句转换。
在宾语从句中经常会出现“疑问词+动词不定式”的结构,它可与“疑问词+主语+情态动词+动词原形”进行同义句转换。
Can you tell me how I can get to the station,
Can you tell me how to get to the station,
六、宾语从句的语序。
宾语从句的语序都用陈述句语序(即正常的主谓语序)
He says that Jim will miss a lot of lessons .
He asked whether we should hold a sports meeting .
- 1 -
Do you know what the population of Dalian is ,
七、宾语从句的时态。
1、主句是一般现在时,从句可根据需要选用任何时态。
He says that he is good at English
He says that he has been ill for two days
I don’t know if he will come tomorrow
2、主句是一般过去时,从句可根据需要用相应的过去某种时态。
(即一般过去时、过去将来时、过去完成时等)
He asked me where I lived
He said that she had been ill for two days
She said that she would return soon
3、当从句讲述的是客观事实或真理时,从句时态不受主句的影响,都用一般现在时。
The teacher said “light travels faster than sound”
He said that the earth is round
特例:Could you t ell me …委婉的语气,常按照一般现在时处理。
Could you tell me where the nearest hospital is ,
八、语从句的从句中不再有助动词。
即一般现在时的助动词do ,does ,一般过去时的助动词did.
Do you like speaking English ,He wants to know .(改为宾语从句)
He wants to know if you like speaking English
九、如果简单句变成了宾语从句,那么其谓语动词要相应的变化。
常见的一般过去时的动词应用过去式;一般现在时的如果主语是第三人称单数的,动词要用单三形式,如果主语不是第三人称单数,动词都用原形;其他时态变成相应的时态的结构即可。
十、宾语从句变否定句。
如果主句的主语是第一人称I或we 时,并且谓语动词多为think、guess、believe等表示心理活动的词时,变否定句要否定转移,即否定主句。
否则,变否定句看从句。
- 2 -
I think chicken can swim (变否定句)
I don’t think chicken can swim
He said that he would go shopping(变否定句) ……
He said that he would not go shopping
十一、宾语从句变反意疑问句
如果宾语从句的主句是第一人称I或we时,变反意疑问句时看从句。
如果主句不是第一人称时则看主句。
I think he is a good student ,isn’t he ,
They want to know if he is a good student ,don’t they ,
