宾语从句和表语从句的用法
宾语从句和表语从句
一.宾语从句的定义置于动词、介词等词性后面起宾语作用的从句叫宾语从句。
宾语从句的语序必须是陈述语序。
谓语动词、介词、动词不定式，v.-ing形式后面都能带宾语从句。
有些形容词（afraid,sure,glad 等）之后也可以带宾语从句。
二.宾语从句中引导词的用法在复合句中作主句的宾语，引导词有：连词：that (that 常可省略),whether, if代词：who, whose, what ,which副词：when ,where, how, why 等。
（一）that引导的宾语从句（在非正式场合that可以省略）可跟that从句做宾语的动词有：say, think, insist, wish, hope, demand, imagine, wonder, know, suppose, see, believe, agree, admit, deny, expect, explain, order, command, feel, dream, suggest, hear, mean, notice, prefer, request, require, propose, declare, report等。
例句：The boy believes that he will travel through space to other planets.注意事项：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.在以下情况中that不能省略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：He said (that) you were too young to understand the matter and that he was asked not to tell you.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。

宾语从句和表语从句概念引入She doesn’t know (that) her father is seriously ill. 她不知道她父亲病得很严重。
Can you tell me how I can get to the railway station?你可以告诉我怎么去火车站吗？The problem is when they can get there. 问题是他们什么时候能到那儿。
The problem is whether we can replace her. 问题是我们能否替换她。
看到宾语从句四个字，你一定想“我学过了”，那么从上面4个句子中，你能够很容易地判断出前两个句子含有宾语从句，而后两个句子的黑体词部分就是表语从句了吧？本单元我们就从复习宾语从句开始，开始对名词性从句中的位置很相似的这两个从句进行一下小结吧。
语法讲解认识名词性从句1. 名词能作什么成分研究下面这个简单的句子：Lily, my sister, is a good girl, and she likes music.主语同位语系动词表语主语谓语宾语分析：此句是and连接的一个并列句，含有两个小句子，and前的句子的结构是“主系表”结构，and后是“主谓宾”结构。
其中主语、表语、宾语和同位语都是名词或名词词组（如a good girl）充当的，当然主语she是代词，而代词是用来代替名词，从而避免重复的词。
换句话说，名词在句子中可以作主语、宾语、表语和同位语。
2. 名词性从句的定义：在句子中起名词作用的句子叫名词从句(Noun Clauses）。
名词从句的功能相当于名词词组，它在复合句中能担任主语、宾语、表语、同位语、介词宾语等，因此根据它在句中不同的语法功能，名词从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。
现在，再次研究“概念引入”中的句子，你对名词性从句有了很清晰的认识了吧？3. 判断下面的名词性从句（划线部分）是什么从句。

英语三大从句语法讲解
英语三大从句在英语中,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;定语从句一、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;An architect is a person who designs buildings. 建筑师是设计房屋的人;whom代替人,是宾格,在定语从句作宾语,在非正式英语常可省略;Do you know the gentleman whom we met in the school library yesterday 昨天我们在学校图书馆里遇到的那位先生你认识吗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;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;Do you know the name of the hotel whose window we can see here 我们这儿能看到窗户的那个宾馆叫什么名字,你知道吗关系代词whose指代先行词hotel,正式用法应该用of which;whose window=the window of which,意思是：the window of the hotel;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;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;： Is she the girl that sells newspapers她是卖报纸的那个女孩吗that可以换成whoWhere is the ice-cream that was in the fridge放在冰箱的冰激凌哪儿去了that可以换成whichIs this the book that you want to buy这是你要买的那本书吗 that可以换成which,在定语从句作宾语,还可以省略二、关系副词引导的定语从句常用的关系副词只有三个：when, where, why,在定语从句中充当时间、地点和原因状语;一关系副词when的用法关系副词when代替的先行词表示的是时间,when在定语从句作时间状语;In Beijing July and August are the months when it rains very often.北京的七月和八月是常下雨的月份;when先行词是months二关系副词where的用法关系副词where代替的先行词表示的是地点,where在定语从句作地点状语;During the Spring Festival I went back to the town where I was brought up.春节期间,我回到了生我养我的家乡;where的先行词是town三关系副词why的用法关系副词why代替的先行词表示的是原因,why在定语从句作原因状语;The reason why I am phoning you is to ask you whether you have got my email.我打电话给你的原因是想问问你是否收到了我的电子邮件;why先行词是reason, 当代英语里why可以用that替代,这时关系代词that就变成了表示原因的关系副词,还可以将why省略三、特殊关系代词as引导的定语从句一在固定搭配as…as, so…as, such…as, the same…as中,as引导定语从句You may take as many books as you want.你想要拿多少书就拿多少;第一个as是副词,修饰many的；第二个as才是关系代词,代替先行词books,在定语从句中作宾语二独立于主句之外,as引导定语从句As we know/ As is known to us, the earth turns around the sun. 正如我们所知,地球围绕太阳旋转;As we know和 As is known to us均为定语从句,as分别作宾语和主语,替代后面的主句;Taiwan is, as you know, an inseparable part of China.你知道,台湾是中国不可分割的一部分;关系代词as指代整个主句,在定语从句中作宾语;四、关系代词who, which与that的区别一关系代词who与that的区别1. 当关系代词用作主语时,多用主格who;He who loses hope loses all.失去希望的人就失去一切;先行词为代词he, they, any, all, one等时,多用whoI met Alice, who told me that she was learning Chinese.我遇见艾丽斯,她告诉我她在学汉语;在非限制性定语从句中,用who2. 当关系代词用作介词后的宾语时,用宾格whom,不用that;The man to whom our headmaster talked just now is our English teacher.我们校长刚才与他谈话的那个人是我们的英语老师;介词与关系代词紧密相连时,只能用宾格whom,不可用主格who注意：介词与关系代词不是紧密相连时,或者说介词放在句子后面时,这时可以用主格who,也可用that,还可以省略关系代词;因此,上面的这句话还可以有如下四种说法：1 The man whom our headmaster talked to just now is our English teacher.2 The man who our headmaster talked to just now is our English teacher.3 The man that our headmaster talked to just now is our English teacher.4 The man our headmaster talked to just now is our English teacher.3. 当关系代词泛指人时,多用that;He is a man that is never afraid of failure.他是个从不怕失败的人;that用来泛指人4. 当关系代词出现在who开头的疑问句时,应用that;例如：Who is the girl that is talking to Tom in English用英语同汤姆交谈的那个女孩是谁避免重复使用who,以免造成误解或语义含混不清二关系代词which与that的区别1. 当先行词为all, much, little以及不定代词anything, something, everything等时,关系代词多用that;All that glitters is not gold. 闪闪发光物,未必尽黄金;She told me everything that she knew. 她把她所知道的一切都告诉了我;2. 当先行词的前面有形容词最高级、序数词或限定词the only, the very, all, every, any, no 等时,关系代词一般都用that;This is the best novel that I have ever read. 这是我读过的最好的一部小说;He is the only person that has been invited to the ball. 他是惟一应邀参加舞会的人;3. 当关系代词出现在which开头的疑问句时,应用that;Which was the hotel that was recommended to the foreign guest 哪一个是推荐给外宾的宾馆这里使用that很明显是为了避免重复which4. 在非限制性定语从句中,关系代词一般只用which;Beijing, which is the capital of the People’s Republic of China, will host the 2008 Olympic Games. 北京是中华人民共和国的首都,将主办2008年奥运会;5. 介词后的关系代词用which,而不用that;She has collected 600 stamps, 60% of which are German stamps. 她收集了600张邮票,其中60％是德国邮票;五、定语从句的位置如前所述,定语从句一般总是直接置于所修饰的名词或代词之后;有时候,定语从句与先行词之间插入了其他的短语,这样它们被分隔了,这种情况下的定语从句被称作隔离定语从句;There was a girl upstairs who was shouting and crying, obviously mad.楼上有一个女孩,大喊大叫;很明显,她疯了;定语从句who was shouting and crying修饰the girl,被upstairs所隔开A new master will come tomorrow who will teach you German.明天要来一位新老师教你们德语了;定语从句置于句末以示强调名词性从句宾语从句一、引导词1由that 引导的陈述句性的宾语从句,在很多动词如say, think, wish , hope, see, believe, agree, expect, hear , feel等动词后;连词that只起连接作用,在从句中不做句子的成分,也无词汇意义,在口语中常被省略;如：I told him that he was wrong.在think, believe, suppose, expect等动词引起的宾语从句中,有时谓语尽管是否定意义,却不用否定形式,而将think 等动词变为否定形式;见语法：否定转移如：I don’t think you are right. 我认为你做的不对在许多带有复合宾语的句子中,that引导的宾语从句经常移到句子的后面,而用it做形式宾语;We think it wrong that he told a lie to everyone 我认为他向每一个人撒谎是错误的2 由连词if、 whether 引导的表示“是否…”的宾语从句;Whether, if 在从句中不做句子的成分,一般情况下,whether和if 可以替换;I don’t know if/whether he will come tomorrow.在介词后面的宾语从句中不用if引导Everything depends on whether we have enough money.宾语从句中有or not时不用if引导.I don’t know whether the movie star will come or not.和不定式连用作宾语时不用if引导Whether to go there or not hasn’t been decided.3由wh-引导的宾语从句;连接代词who, whom, whose, what, which和连接副词when, where, why, how 等连接的宾语从句,它们在句中即有连接从句的作用,又在句中充当句子的成分;Do you know which film they are talking about which做定语I don’t know where he lives. where 做地点状语二、宾语从句的语序,宾语从句的语序必须是陈述语序,既连接词+主语+谓语+其他成分 I believe that they will come soon.特例：有下列常见的问句,作为从句出现,是“不改变语句顺序”的;1. What's the matter2. What's wrong3. What's up4. What's the problem5. What's your trouble三、宾语从句的时态;宾语从句的时态受主句的限制,即：主句是一般现在时态,从句根据实际情况而定；主句是一般过去时态,从句用相应的过去的时态;如果从句的动作发生在主句之前,则从句要用过去完成时态;1 She says that she is a student.→ She said that she was a student.2She says that she will fly to Japan in a week. → She said that she would fly to Japan in a week.3She says that she has finished her homework alre ady. → She said that she had finished her homework already.1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.2Could you tell me…是用来征询对方的意见,语气委婉,并不表示过去;Could you tell me when we will visit the History Museum注意事项：3由陈述句变成宾语从句时,要注意人称的变化;She said: “I have been to England before.” → She said that she had been to England before. She asked me: “Do you like maths” → She asked me if I liked maths.4宾语从句与简单句的交换;由连接代词和连接副词引导的宾语从句,如果宾语从句的主语和主句的主语是同一个人时,可以用“疑问词+不定式”做宾语的简单句结构;I don’t know what I should do next. → I don’t know what to do next.DO SOME EXERCISES:you see AA. what he’s readingB. what is he readingC. what does he readD. he reads what2.

Why is our Chinese team be able to beat Korea同位语从句一一般来说,在主从复合句中,用作同位语的从句叫同位语从句;它通常跟在某些名词之后,用以说明或解释该名词表示的具体内容;可以跟同位语从句的名词通常有：advice, decision, fact, hope, idea, information, message, news, promise, proposal, reply, report, suggestion, word消息,problem, question, doubt, thought等;eg: They were delighted at the news that their team had won.当听到他们队获胜的消息时,他们欣喜若狂;有时同位语从句可以不紧跟在被说明的名词后面,而被别的词隔开; 如：The thought came to him that Tom might have returned the book.他突然想起汤姆可能已经还了书了;二引导词1. The news that Mr. Li will be our new English teacher is true.2. He hasn’t made the decision whether he will go there.3. The question who should do the work is being discussed at the meeting.4. I have no idea what the boy is doing in the next room now.5. We haven’t yet settled the question where we are going to spend our summer vacation this year.6. I have no idea how I can get to the railway station.7. I have no idea when he will be back．小结：① that引导同位语从句时无词义,也不充当任何成分,但通常不可以省略,如句1；② whether引导同位语从句时意为“是否”,通常不能用if来代替, 如句2;③ 连接代词who, what等可以引导同位语从句,如句3, 4；④ 连接副词where, how, when等可以引导同位语从句, 如句5,6,7;三 that 引导的同位语从句和定语从句① 意义不同：同位语从句用来进一步说明前面名词的内容；而定语从句用来修饰、限定前面的先行词;试比较：1. The news that our team has won the final match is encouraging.2. The news that you told us is really encouraging.② that的功能不同：that引导同位语从句时是一个纯连词,不充当任何成分；而引导定语从句时,不仅起连接作用,而且还指代先行词并在从句中充当主语、宾语等成分;试比较：1. Dad made a promise that he would buy me a CD player if I passed the English test.2. Dad made a promise that excited all his children.③ 可否省略：that在引导同位语从句时,通常不可省略;在引导定语从句时,若在从句中作宾语,通常可以省略,若作主语则不可以省略;DO SOME EXERCISES:I. 请用适当的词填空,使下列句子意思完整;1.
