英语语法之宾语从句
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。
宾语从句知识点
宾语从句知识点宾语从句是英语语法中的一个重要知识点，对于我们理解和运用英语句子有着关键作用。
首先，我们来了解一下什么是宾语从句。
宾语从句就是在复合句中作主句宾语的句子。
简单来说，就是一个句子充当了另一个句子中的宾语成分。
宾语从句有三大要素需要我们注意。
第一是引导词。
常见的引导词有 that（在从句中不充当成分，无实际意义，口语或非正式文体中常可省略）、if ／ whether（表示“是否”）、连接代词（what, who, whom, whose, which 等）以及连接副词（when, where, why, how 等）。
比如说，“I think that he is a good student” 这里的“that he is a good student”就是宾语从句，由 that 引导，在这个句子中 that 可以省略。
再比如，“I don't know if ／whether he will come” 这里用 if ／ whether 引导，表示“是否”。
第二要素是语序。
宾语从句要用陈述句语序，也就是主语在前，谓语在后。
例如，“Can you tell me where the post office is?” 不能说成“Can you tell me where is the post office?” 。
第三要素是时态。
当主句是一般现在时，宾语从句的时态可以根据实际情况而定。
如果主句是一般过去时，宾语从句通常要用相应的过去时态（一般过去时、过去进行时、过去将来时、过去完成时）。
但如果宾语从句所表达的是客观真理、自然现象、科学原理等，不论主句是什么时态，宾语从句都要用一般现在时。
比如，“The teacher toldus that the earth moves a round the sun” 这里地球绕着太阳转是客观真理，所以从句用一般现在时。
宾语从句在实际运用中有很多情况。

小编在这里整理了宾语从句英语语法供大家阅读，希望能帮助到您。
宾语从句英语语法主从复合句包含两个或多个主谓结构，其中一个(或多个)主谓结构充当句子某一(些)成分，如宾语、状语、定语等等。
充当某一成分的句子称为从句，带有从句的句子称为主句。
从句对主句的关系是从属关系。
主句和从句之间有一定的连接词加连接。
宾语从句如果一个句子充当宾语，称为宾语从句。
其主要句型结构如下：1. 动词+that引导的从句常用动词有hope, hear, see, know,think, believe, agree, feel, find, guess, mean, promise, learn等。
例如：I hope that you will enjoy our performance.我希望你会喜欢我的演出。
I think that the new science fiction film is interesting.我认为那部新的科幻片很有趣。
He learnt that David would come to China with his family soon.他得知戴维不久将和他全家来中国。
Do you believe that Li Ying will win a prize for her painting?你认识李英的画会得奖吗?提高英语学习效率的方法第一：明确自己确实有必要学习英语，并且有足够的时间。
学习英语毕竟不是轻松的事情，需要耗费大量的精力和时间。
我们说英语首先是一门知识，知识的掌握离不开记忆，同时英语又是一种技能，听说读写的能力就是一种技能，而技能的掌握需要重复训练才能掌握。
英语具有的知识和技能特性决定了学习英语不需要很高深的智力，学习英语不是创造发明，不需要刻苦钻研，所以只要有记忆力的人理论上都可以学会英语。
英语中的宾语从句
英语中的宾语从句宾语从句是英语中一种重要的语法结构，它在句子中充当宾语的作用。
宾语从句常出现在动词的宾语位置，能够完整表达句子的意思。
在本文中，我们将深入研究宾语从句的构成和用法。
首先，宾语从句的构成一般由连接词引导，常见的连接词有“that”、“whether/if”以及特殊疑问词。
例如：I know that heis coming.（我知道他要来。
）在这个句子中，“that he is coming”就是一个宾语从句，起到了宾语的作用。
其次，宾语从句可以包含各种陈述句、疑问句和感叹句。
当宾语从句表示陈述或肯定时，使用连接词“that”。
例如：She said that she would help us.（她说她会帮助我们。
）当宾语从句表示疑问时，使用连接词“whether/if”。
例如：He asked whether/if I could swim.（他问我是否会游泳。
）当宾语从句表示感叹时，常使用特殊疑问词“how”。
例如：I can't believe how beautiful she is!（我无法相信她有多美！）宾语从句在使用时需要注意几个要点。
首先，连接词“that”在口语中通常可以省略，但在形式较正式的文体中应保留。
例如：Hetold me (that) he loved me.（他告诉我他爱我。
）其次，连接词“that”在宾语从句中不充当任何成分，只起连接作用，不可替换为其他连接词。
最后，特殊疑问词在宾语从句中起问句的作用，但不再引导主语和谓语动词。
例如：I don't know what he is doing.（我不知道他在做什么。
）宾语从句在句子中起到了连接主句和从句的作用，使得句子更加完整、准确地表达。
在实际运用中，我们要灵活运用宾语从句，注意语法的准确性和句子的流畅性。
通过大量的练习和阅读，我们可以逐渐掌握宾语从句的使用技巧，提高自己的英语水平。

宾语从句一、宾语从句的定义在句中起宾语作用的从句叫宾语从句。
引导宾语从句的连接词：连词：that (that 常可省略),whether, if代词：who, whom，whose, what ,which，whatever，whichever，whoever等副词：when ,where, how, why 等。
宾语从句分三类：动词的宾语从句；介词的宾语从句；形容词的宾语从句。
（1）动词的宾语从句：作动词的宾语大多数及物动词可以带宾语从句，有些动词短语也可以带宾语从句。
I heard that he would come here later on.（2）介词的宾语从句：作介词的宾语一般情况下，介词后只用wh-类连接词引导宾语从句。
He said nothing about who broke the window last night. （3）形容词的宾语从句：作形容词的宾语在afraid，certain，glad，happy，pleased，sure，surprise，satisfied，sorry等表示感情的形容词后可接宾语从句。
I’m sorry you are having trouble in making friends.二、宾语从句中引导词（连接词）的用法1.that，if/whether引导that，whether，if引导宾语从句时都只起连接作用，不作句子成分。
That 无意义且可省略，而whether/if意为“是否”，故不可省略。
He told me that he would go to the college the next year.I don’t know if there will be a bus any more.Nobody knew whether he could pass the exam.2.连接代词引导当连接代词who, whom，whose, what ,which，whatever，whichever，whoever 等引导宾语从句时，可以在宾语从句中作主语、宾语、表语、定语等成分。
每个连词都有自己特定的意义，一般不能省略。
The book will show you what the best CEOs should know.Do you know who has won Red Alert game?Have you determined whichever you should buy,a Motorola or Nokia cell phone?3.连接副词引导当连接副词when，where，why，how，however等引导宾语从句时，可以在从句中充当状语，表示时间、地点、方式、原因等。
每个副词都有自己特定的意义，一般不能省略。
有时how many和how much也可以引导宾语从句。
He didn’t tell me when we should meet again.Could you please tell me how you use the new panel?None of us knows where these new parts can be bought.三.宾语从句的语序宾语从句的语序是陈述句语序即：连接代词/副词+主语+谓语+其他成分。
即使主句为疑问句语序，从句也用陈述句语序。
I don’t know what they are looking for.Could you tell me when the train will leave?四.宾语从句的时态1.主句是一般现在时或将来时，从句根据实际情况使用任何时态。
例句：The headmaster hopes everything goes well.I hope you will find these ideas useful.2.主句是过去时态，从句须用过去时态的某种形式。
例句：Sh e was sorry that she hadn’t finished her work on time.3.当宾语从句表示的是一个客观真理或者事实时，即使主句是过去时，从句也用一般现在时态。
例句：The teacher told his class that light travels faster than sound.五、宾语从句的否定转移1.当主句谓语动词是 think, believe, suppose, expect 等词，而宾语从句的意思是否定时，常把否定转移至主句表示。
例句：I don’t think it is right for him to treat you like that.2.主句的谓语动词是think ,believe, imagine, suppose, consider, expect, fancy, guess等,并且主句的主语是第一人称而且为一般现在时,从句的否定词一般要转移到主句上来,其反义疑问句一般与宾语从句一致. 例句：I don’t believe that man is killed by Jim,is he? 我认为那个人不是Jim所杀的,是不是?I expect our English teacher will be back this weekend, won't she/he?We suppose you have finished the project, haven't you?3.如果宾语从句中有某个含有否定意义的形容词或副词(不包含带有否定前缀的词，如：unhappy，unfair，dislike等),其反义疑问句要用肯定形式.例句：We find that he never listens to the teacher carefully, does he? 我们发现他从不仔细听老师讲课，是不是？4.当主句的主语是第二、三人称时，其反义疑问句一般与主句保持一致。
例句：Your sister supposes she needs no help, doesn't she?You thought they could have completed the project, didn't you?They don't believe she's an engineer, do they?She doesn't expect that we are coming so soon, does she?六、宾语从句中that不能省略的情况1、当句中的动词后接多于两个由that引导的宾语从句时，第一个that可省，但后面的that不可省。
例句：I believe（that）you have done your best and that things will get better．2.当主句的谓语动词与that宾语从句之间有插入语时，that一般不可省。
例句：Just then I noticed, for the first time, that our master was wearing his fine green coat and his black silk cap.3.当that从句是双宾语中的直接宾语时，that不可省。
例句：I can’t tell him that his mother died.4.当it作形式宾语时例句：She made it clear that she had nothing to do with him．许多带复合宾语的句子，that引导的宾语从句经常移到句子后部，而用it作形式宾语。
5.当宾语从句前置时例句：That our team will win，I believe．6.当that作learn, suggest, explain, agree, wonder, prove, mean, state, feel, hold等动词的宾语时。
例句：She suggest that we get up early.七、宾语从句中只用whether或只能用if的情况1.只能用whether，不能用if：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）I don't know whether ／if he does any washing or not．（＝I don't know whether or not he does any washing．）I wonder whether we stay or whether we go．②在介词之后用whether。
如：I'm interested in whether he likes English．We're thinking about whether we can finish the work on time．③在不定式前用whether。
如：He hasn't decided whether to visit the old man．He hasn't decided whether to go by bus or by train．④whether置于句首时，不能换用if。
如：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。
如：Whether she will come or not is still a question．⑥若用if会引起歧义时，则用whether。
如：Please let me know if you like the book.可理解为：b．If you like the book，please let me know．2.只能用if不能用whether的情况1）if引导条件状语从句，意为“如果”The students will go on a picnic if it is sunny.2）if引导否定概念的宾语从句时He asked if I didn’t come to school yesterday.3）引导状语从句even if（即使）和as if（好象）时He talks as if he has known all about it.练习题1(1)．I don’t think he is right,__________?A．isn’t he B．is he C．do I D．don’t I(2).
