初中英语从句语法讲解
从句
从句按其在复合句中的作用,分为主语从句、表语从句、宾语从句、定语从句和状语从句等。（参见以下各条）
3、各从句在句子中的位臵以及用法：
(1) 表语从句：在句子中作连系动词的表语的从句,它位于主句中的系动词之后。
例如：That is why he did not come to school yesterday. / It is because you are so clever.
(2) 宾语从句：在句子中作及物动词或介词的宾语。
①基本形式：（主句＋）连词+从句主语+从句谓语+...
②关于宾语从句连词的选择：
若从句来源于一个陈述句,那么,连词用that,在口语中that可以省略;
若从句来源于一个一般疑问句,连词则用if 或whether;
若从句来源于一个特殊疑问句,则连词就是疑问词(如what,who,where,when等) 例如：They believe that the computer will finally take the place of human beings.(他
们相信计算机终将代替人类。) (从句本来就是陈述句)/ I wonder whether I should say
something for him to the headmaster. (我不知道是不是该为他在校长跟前说点什么。) (从
句来源于一般问句Shall I say something for him to the headmaster?)/ He asked me where
he could get such medicine. (他问我在哪儿能搞到那样的药。) (从句来源于特殊问句Where
can he get such medicine? )
③宾语从句的时态问题：如果主句是现在时,从句则用现在某一时态,甚至可以用过去时；
如主句是过去时,从句则相应地使用过去某一时态,遇到客观真理时仍然用现在时。如：I think
I will do better in English this term.(我想本学期我的英语会学得好点。)/ The teacher
asked the boy if the earth is round. (老师问那个男孩地球是不是圆的。)
④下列结构后面的从句一般也作为宾语从句看待：
be sorry / afraid / sure / glad +that从句,如：I’m sorry I’m late. (对不起,我迟到
了。) / I’m afraid he isn’t in at the moment. (恐怕他此刻不在家。)
(3) 状语从句：在复合句中作状语,其位臵可以在主句前或主句后。状语从句可以分为时间、地点、原
因、目的、结果、比较、让步、条件等几种。状语从句由从属连接词引导。
时间状语从句通常由when ,as ,while, after, before, since, as soon as ,since, till (until), while, whenever等引导。时间状语从句一般放在句首或句尾,特别注意,时间状语从句不允许
使用将来时,而应该用现在时替代。如：When you finish the work, you may go out to play with Sam.(你完成工作就可以出去和Jim一起玩了。) / I won’t leave until Mum comes back.
(妈妈回来了我才会走。)
地点状语从句通常由 where, wherever等引导。如：Go back where you came from! (哪里来还滚到哪里去！) / I will never forget to catch the thief who stole my necklace wherever he may be. (我永远也不会忘记去抓住那个偷我项链的贼,无论他会在哪里。) 原因状语从句通常由because, since, as等引导,一般放在句首或句尾。如：He went abroad because his father had found a good university for him. (他出国了,因为他父亲给他找了一所好大学。)
目的状语从句通常由so that..., so...hat..., in order that...等引导,往往放在句尾,从句中通常含有can / could / may / might等情态动词。如：He got up earlier so that he could catch the first train. (他起身更早为的是赶上第一班车。)
结果状语从句通常由so that..., so...that... 等引导,放在句尾。结果状语从句一般表示已经发生的事情,故多为过去时态。如：He lost so many bikes that he decided never to buy a new one. (他丢了那么多辆自行车,他决定再也不买新车了。)
比较状语从句通常由as, than, as (so)...as等引导,一般省略从句的谓语部分,只剩下名词或代词(用主格或宾格均可)。如：Jane is much taller than I/me. (Jane比我高多了。) / I don’t have as many books as you (do). (我书没有你多)
让步状语从句通常由though (although), as, even if( even though), however, whatever等引导。如：Even if you pay the debt(债务) for me, I will not thank you because it has nothing to do with me. (即使你替我还了债我也不会感谢你,因为它与我毫无关系。) / He wears a T-shirt though it is very cold. (他穿了一件T恤衫,尽管天很冷。) 条件状语从句通常由if, unless, as long as等引导,条件状语从句一般放在句首或句尾,特别注意,时间状语从句不允许使用将来时,而应该用现在时替代。You will certainly fail in the coming final exams unless you work much harder. (即将来到的期末考试你肯定考不及格,除非你更用功。) / If it doesn’ t rain tomorrow, we shall go hiking. (如果明天不下雨我们就要去徒步旅行。)
[注意] 1、because与so；(al)though与but；if与so不可以同在一个句子中成对出现。
2、时间、条件、原因,让步状语从句放在句首时需要用逗号与主句隔开。
(4) 定语从句：在复合句中作定语用修饰句子中某一名词或代词的从句叫定语从句。
①定语从句的位臵：放在名词或代词的后面。如：The man who has an umbrella in his hand is
my uncle. (手上抓了一把雨伞的人是我的叔叔。)
②语法术语的改变：被修饰的名词或代词称为先行词；引导定语从句的连接词称为关系词,其中
that、which、who称为关系代词,where、when、how称为关系副词。
③关系代词或关系副词的作用：
关系代词who、whom和whose指人,分别在从句中作主语、宾语和定语。which指物that多指物, 有时也指人,它们在从句中可以作主语或宾语。定语从句中关系代词作从句宾语时可以省略。
This is the thief (that/who/whom) we have been looking for these days. (这个就是我们近日一直在找的小偷。)/ Please find a room which is big enough for all of us to live in. (请找一间足够大能住下我们全体的房间。)
关系副词when或where引导定语从句时,它们在从句中分别作时间状语和地点状语。如：This is the room where they had a quarrel a week ago. (这是一个星期前他们吵架的房间。) / I can never forget the day when I first saw you. (我永远不会忘记第一次见到你的日子。)
④限制性定语从句和非限制性定语从句。限制性定语从句在句中不能省略,否则主句意思就不完
整。非限制性定语从句和主句之间往往用逗号分开,这种从句是一种附加说明,如果从句子中省去,也不致于影响主句的意思。如：She spent the whole evening talking about her latest book, which none of us had heard of. (她一个晚上都在谈论她最近的书,我们一个人都没有听说过那本书。)
[注解]
1、关系代词只能用that的情况：当先行词是指事物的不定代词(all, anything等),或先行词部分
含有最高级,或含有序数词时,不能用其他的关系代词,只能用that. 如：All that Lily told me seems untrue.(Lily告诉我的话似乎不真实。)/ Can you give me anything that has no sugar inside? (能不能给我点里面没有糖的东西？) / This is the first two-story bus that runs in our city. (这是第一辆运行于我市的双层公交车。)
2、关系代词在从句中作主语时一般用who(指人)、that(指物),而不用that指人或用which指物。
如：Do you know the woman who is weeping in the corner? (你认识那个在角落里哭泣的女人吗？) / Do not tell me any words that have nothing to do with me. (跟我无关的话,请一个字也不要说。)
3、关系代词作从句的宾语时,常用which或whom,较少使用that或who,而且,关系代词常常省略。
如：Tom’s father was the first parent whom our teacher talked to. (Tom的父亲是我
们老师第一个谈话的人。)
4、当关系代词紧跟在介词后面时,必须用which或whom,而当介词移到句尾时,则又可以使用that
或who. 如：This is the room in which Miss Li once lived. (= This is the room Miss
Li once lived in.) (这是李小姐曾经居住过的房间。)
(5) 主语从句：在句子中充当句子主语的从句叫主语从句。位于谓语动词之前。通常由that,whether
以及疑问连词引导。一般情况下,常用it替代主语从句,而将主语从句移到句尾。如：When we
should start is still a question. (我们该在什么时候开始还是个问题呢。)
十五、直接引语和间接引语(初中不作特别要求)
1、直接引语和间接引语：在陈述句中,直接引用说话人原来的语句,称为直接引语。在书写时,直接引语用引
号。用自己的词语来转述表达原来说话人说的内容,称为间接引语。
2、直接引语改变为间接引语：
1、直接引语如果是陈述句,变为间接引语时应注意以下各点：
①不用引号,而用连接词that,但有时可省略。
②人称作相应变化；
③主句里的动词如果是过去时,间接引语中的时态一般应作相应改变：一般现在时变一般过去时；一
般将来时变过去将来时；现在进行时变过去进行时；现在完成时变成过去完成时；一般过去时变成过去完成时；但一般过去时如与一个具体的过去时间连用,则时态不变。
如：He says,"I am not from the USA.”→He says that he is not from the USA.
Mr Smith said to his girl friend,“ I haven’ t seen you for a long time.”
→Mr Smith said to his girl friend that he had not seen her for a long time.
2、直接引语如果是一般疑问句,变为间接引语时,需用从属连接词whether或if引导,词序要改变。如：
Lin Tao said to Miss Green, "Is it made in China?”→Lin Tao asked Miss Green if it was made in China.
3、直接引语如果是特殊疑问句,变为间接引语时,需用疑问词引导,词序是：连词+主语+谓语。
如：Lucy said to me, “How can I help?”→Lucy asked me how she could help.
4、直接引语如是祈使句,变间接引语时,须将祈使句变为动词不定式,并在动词不定式前用tell, ask,
order. 如：He said to the little boy,“ Come here, young man! ”
→He asked the little boy to go there.
5、直接引语变为间接引语时,指示代词以及表示时间和地点的词或词组应作相应变化：
初中英语语法——三大从句汇总(重点笔记)
初中英语语法——三大从句汇总 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）。以 下是一些基本的从句的语法知识点 A、定语从句专项讲解与训练 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. 先行词定语从句 在所有的从句中，算定语从句最难掌握，因为汉语里没有定语从句，汉语 里只有定语，而且总是放在名词之前来修饰名词。 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： 先行词主格宾格所有格 人 who whom whose 物 which which whose of which 人、物 that that — （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。 I will never forget the teacher who taught us chemistry in the first

初中英语定语从句的用法解析
初中英语定语从句的用法解析 【摘要】定语从句是一种形容词的关系从句。它由关系代词或关系副词引导（1）。初中英语中的定语从句仅限于限制性定于从句，但对初中生来说，定语从句既是一个重点，也是一个难点。 【关键词】定语从句先行词关系代词关系副词 一、英语中的定语从句与汉语中的定语位置不同。 在复合句中，修饰某一名词或代词的从句叫做定语从句。英语中的定语从句始终要放在被修饰的词之后，而汉语中的定语则放在被修饰词之前。如： The man who / that I saw at the school gate yesterday is my English teacher. 先行词定语从句 昨天我在校门口看见的那个人是我的英语老师。 二、英语从句中的句型结构比较复杂，有先行词、关系代词或关系副词。被定语从句修饰的词叫先行词，引导定语从句的关联词有关系代词或关系副词。限制性关系分句和它的先行项的所指意义有着不可分割的联系（2）。关系代词或关系副词放在先行词和定语从句之间起纽带作用，关系代词或关系副词在定语从句中要充当一个成分。关系代词在句中可作主语、宾语或定语，关系副词在句中作状语。如： I am waiting for the boy who /that is wearing a red coat. （主语） 先行词关系代词 我正在等穿着红色外套的那个男孩。 The dictionary that / which my sister gave me last Sunday is very expensive.(宾语) 先行词关系代词 我姐姐上周星期天给我的那本字典很贵。 The woman is his mother whose name is Linda Brown. (定语) 先行词关系代词 那个是他的母亲，名叫琳达·布朗。 That is the house where my father used to live.(状语) 先行词关系副词 那是我父亲曾经居住过的房子。 三、初中英语中的定语从句关系代词或关系副词的具体用法。 1. who指人（也可用that），在定语从句中作主语，也可作宾语。如： Yesterday I helped an old man who / that lost his way. （主语） 昨天我帮助了一位迷路的老人。 Mr Wang is the man (who / that / whom )you met in the zoo this morning.(宾语) 王先生就是今天早上你在动物里遇到的那个人。 注意：关系代词who指人,作宾语时，可用whom代替；作宾语时，关系代词可省略。作其它成分，关系代词则不能省略。 2. whose指人，也可指物。在定语从句中作定语。 The boy whose mother is ill is staying at home to look after her today. 其母亲生病的那个男孩今天呆在家里照顾她。 I have a story book whose cover is red. 我有一本封面是红色的故事书。 3. which指物（也可用that），在定语从句中作主语，也可作宾语。如： Football is a game which / that is liked by most boys. （主语） 足球是被大多数男孩喜欢的运动。 I don’t believe the news which / that Tom won the game. (宾语)
初中英语语法宾语从句讲解-专项练习及答案
初中英语语法宾语从句讲解 小口诀： 宾语从句三注意，时态语序引导词；主句一般现在时，从句不需受限制； 主句一般过去时，从句须用相应时；陈述转化that引，一般疑问用if/whether, 特殊问句疑问词，引导词后陈述式。 一．基本讲解来源：直接引语变间接引语 概念:在句中担当宾语的从句叫宾语从句。 Eg: He said,“I am good at drawing”. He said he was good at drawing. (动词宾语) 1.引导词 (1) that引导宾语从句时，通常用陈述句充当, that可省略。 Eg: She said,“I want to go there ”She said (that) she wanted to go there. (2) whether 或if 引导的宾语从句,由一般疑问句/选择疑问句充当，陈述语序。 Eg: “Are you interested in geography?” she said. She asked if/whether I was interested in geography. I wonder if /whether she has told the new to Li Lei . I’m not sure whether he will come or not. 注意：一般情况下，whether 和if 可以互用，但有些情况例外 a. 介词短语后只用whether 不用if eg: We are talking about whether we'll go on the panic. b. 引导词与动词不定式或or not 连用时，只用whether. eg:I can?t say whether or not he will come on time c. if当如果讲时,引导的是条件状语从句，表示‘如果’，不能用whether. Eg: If you want to be a good teacher, it will take times. Whether you can succeed depends on how much effort you pay. (3).特殊疑问词引导宾语从句时，不可省略，陈述句语序。 特殊疑问词为：how , when, where, why ,which whose. E.g. …What do you want?? He asked. He asked me what I wanted. I have no idea where he is now. I don?t know how to deal with it. He asked whose handwriting is the best in the class. 2.宾语从句时态 a.主句为一般现在时，从句不受主句的限制 eg: Do you know if/whether he has seen the film? I?m sorry to hear that your father is ill. She says she is going to go to Beijing next week. He tells me that his sister came back yesterday. b.当主句是一般过去时，从句用过去的相应某种时态 She didn?t know why the boy was late again. (过去一般) I didn't know if/whether he had seen the film.（过去完成） I wondered when she was going to America.（过去将来） 注意：当主句是一般过去时，而从句表示的是客观真理，自然现象，科学原理，格言等，从句仍然要用一般现在时。例如： Eg: He said （that the earth moves round the sun. / that light travels much faster than sound.）The teacher told us （seeing is believing.）
(精华版)初中英语语法基本从句汇总
（精华版）初中英语语法基本从句汇总从句的共同特点 从句是指在一个句子中充当一个成分的句子，充当什么成分就叫什么从句，如：充当宾语就叫宾语从句，充当定语成分就叫定语从句。 从以上定义中我们可以得出关于从句的一个最大特点：从句是句子。 从句的共同特点：1.从句都有自己的连接词2.从句都是陈述语序(陈述语序就是主语在前，谓语在后，如：He is a teacher主语He在谓语is之前，因此是陈述语序，而Is he a teacher?主语He在谓语is之后，因此不是陈述语序。) 1宾语从句 宾语从句是指在一个句子中充当宾语的句子，如：He said that he wanted to be a teacher when he grew up. 宾语从句的特点： ①宾语从句有自己的连接词 ②宾语从句用陈述语序 ③宾语从句的时态 1
①宾语从句的连接词：宾语从句的连接词包括that、if/whether(是否)、特殊疑问词。 ②宾语从句的语序; A.宾语从句的连接词后加陈述语序(主语在前，谓语在后),如：I want to know if he can come tomorrow B.当连接词本身又是宾语从句的主语时，后面直接加谓语动词，如：She asked me who had helped him. ③宾语从句的时态，只要记住以下口诀就可以了“主现则从任，主过则从过，客观真理一般现” A.主现则从任：主句如果是一般现在时，则从句根据时间状语需要从八种时态中任选一种，如：1.He tells me he likes English very much(一般现在时) B.主过则从过：主句如果是一般过去时，则从句根据时间状语需要从四种带“过”字的时态中任选一种，带“过”字的时态分别是如：一般过去时，过去进行时，过去将来时，过去完成时。 如：He told me that he liked playing football(一般过去时) C.客观真理一般现:客观真理永远用一般现在时。 如：1.He says the moon goes around the earth. 2状语从句 2

初中英语定语从句讲解及练习(教师版) 一.定语从句及相关术语 1.定语从句：修饰一个名词或代词的从句称为定语从句，一般紧跟在它所修饰的先行词后面。 2.关系词：引导定语从句的关联词成为关系词 关系词有关系代词和关系副词。关系代词有that, which, who, whom, whose, as 等； 关系副词有where, when, why等。 关系词常有3个作用：1，引导定语从句。2，代替先行词。3，在定语从句中担当一个成分。 二.关系代词引导的定语从句 1.who指人，在从句中做主语 (1) the boys who are playing football are from class one. (2) yesterday i helped an old man who lost his way. 2. whom指人，在定语从句中充当宾语，常可省略。 (1) mr. liu is the person (whom) you talked about on the bus. (2) mr. ling is just the boy whom i want to see. 注意：关系代词whom在口语和非正式语体中常用who代替，可省略。 (3) the man who/whom you met just now is my friend. 3. which指物，在定语从句中做主语或者宾语，做宾语时可省略 (1) football is a game which is liked by most boys. (2) this is the pen (which) he bought yesterday. 4. that指人时，相当于who 或者whom；指物时，相当于which。在宾语从句中做主语或者宾语，做宾语时可省略。 (5) the number of the people that/who come to visit the city each year rises one million. (6) where is the man that/whom i saw this morning? 5. whose通常指人，也可指物，在定语从句中做定语 (1) he has a friend whose father is a doctor. (2) i once lived in a house whose roof has fallen in. whose指物时，常用以下结构来代替 (3) the classroom whose door is broken will soon be repaired. (4) the classroom the door of which is broken will soon be repaired. (5) do you like the book whose cover is yellow? (6) do you like the book the color of which is yellow? 三.介词+关系代词引导的定语从句 关系代词在定语从句中做介词宾语时，从句常由介词+关系代词引导 (1) the school (that/which) he once studied in is very famous. (2) the school in which he once studied is very famous. (3) tomorrow i will bring here a magazine (that/which) you asked for. (4) tomorrow i will bring here a magazine for which you asked.

初中英语宾语从句讲解、练习与答案
宾语从句 一、考点、热点回顾 （一）宾语从句的种类 宾语从句是一种名词性从句，在句中作及物动词的宾语，或介词的宾语，或形容词的宾语。根据引导宾语从句的不同连词，宾语从句可分为三类。 1. 由that引导的宾语从句。that只有语法作用，没有实在的意义，在口语 和非正式文体中可以省略。例如： He said (that) he wanted to stay at home. She doesn’t know (that) she is seriously ill. I am sure (that) he will succeed. 2. 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。例如： Do you know who (whom) they are waiting foe？ He asked whose handwriting was the best. Can you tell me where the bus stop is？ I don’t know why the train is 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。例如： I hear (that) physics isn’t easy. I think (that) you will like this school soon. Can you tell me how I can get to zoo？ Please tell me when we’ll have the meeting. （三）宾语从句的时态 1. 如果主句的时态是一般现在时，宾语从句该用什麽时态就用什麽时态。 如：I don’t think (that) you are right. Please tell us where he is. Can you tell me how I can get to the railway station？ 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）。例如： He asked what time it was. He told me that he was preparing for the sports meet. He asked if you had written to Peter.
初中英语语法名词性从句
名词性从句 在句子中起名词作用的句子叫名词从句。名词从句的功能相当于名词词组，名词从句又可分为主语从句、宾语从句、表语从句和同位语从句。 一．主语从句 1.作句子主语的从句叫主语从句。主语从句通常由从属连词that,whether, if和连接代词what, who, which, whatever,whoever以及连接副词how, when, where, why等词引导。that在句中无词义，只起连接作用。连接代词和连接副词在句中既保留自己的疑问含义、又起连接作用，在从句中充当从句的成分。主语从句要求使用陈述句语序。 What surprised me most was that the little girl could play the violin so well. How he was successful is still a puzzle. That he is going aboard made him excited. Where the English party will be held has not yet been announced. 注：有时为避免句子头重脚轻，常用形式主语it代替主语从句作形式主语放于句首，而把主语从句置于句末。主语从句后的谓语动词一般用单数形式。 It is interesting that you like him. It is a pity that you can not go to the party tonight. 2.连接词的选用 （1）that和what的选用 that和what都可引导主语从句。what除起连接作用外，还在名词性从句中充当某些成分，可作从句的主语、宾语或表语。而that在名词性从句中不充当任何成分，无词义，只起连接词作用。 What he wants is a book. 他想要的是一本书。 That light travels in straight lines is known to all. 众所周知，光线沿直线运行。 （2）if和whether的选用

初中英语语法三大从句总结
初中英语语法三大从句总结 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）。 宾语从句 一、定义:在句子中起宾语作用的从句叫做宾语从句。 二、连接词 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. 三、时态 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. 定语从句 一、定义:在复合句中修饰名词、代词的从句叫定语从句。 二、先行词 先行词指人who /that 先行词指物which/ that 定语从句一般紧跟被修饰的名词或代词（即先行词）后
初中英语宾语从句专项练习(完整版)
宾语从句基本讲解与练习 一、概念 在句子中起到宾语作用的从句叫做宾语从句。 二、连接词 1. 陈述句转化成宾语从句时，引导词用that (在非正式场合that可以省略)。that在从句中不充当任何成分，也没有实在意思，只起到连接作用。 No one told Jack (that) there would be a class meeting the next day.没有人告诉杰克第二天有班会。 Little Tom was afraid (that) he couldn’t pass the exam. 小汤姆担心这次考试不及格。 【拓展1】可跟that从句做宾语的动词有：say, think, wish, hope, imagine, wonder, know, believe, agree, explain, feel, suggest, hear, mean, notice 等。 【拓展2】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。 I don’t think (that) he can give a speech at the meeting.我认为他 不会在会上发言的。
【拓展3】在think, believe, imagine, suppose, guess, hope 等动词以及I’m afraid 等后，可用so代替一个肯定的宾语从句，用not代替一个否定的宾语从句。 eg: --- Do you believe he will come 你相信他会来吗 --- I believe so. 我相信会。 --- I don’t believe so. (或I believe not.) 我相信不会。 2. 以whether或if 引导的宾语从句, 主要用来引导一般疑问句意思或选择疑问句意思的宾语从句，从句是陈述句语序。whether或if在从句中不充当任何成分，意为“是否”。 eg: “May I use your knife” He asked me. → He asked me if he might use my knife. 【注意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。 eg: “Do you know her telephone number” He asked me. → He asked me whether I know her telephone number. 【注意2】：一般情况下，whether 和if 可以互用，但有些情况例外。 ①当从句做介词的宾于是只用whether 不用if。 eg: We are talking about whether we'll go on the picnic. 我们在讨论是否去野餐。 ②引导词与动词不定式或or not 连用时，只用whether。 eg: Please let me know whether to do next step. 请让我知道是否开展下一步行动。
中考英语 定语从句讲解
定语从句 请看下面的句子： （一）概念: 定语从句：在复合句中修饰名词或代词的句子，叫定语从句。 先行词：被定语从句修饰的词叫先行词。 关系词：引导定语从句的词叫关系词。 （二）定语从句的分类 Ⅰ、限定性定语从句：从句不可少，没有它，先行词的意思不明确，主句也不完整。与先行词之间不用逗号。 e.g:This is the book that/which I want.

(完整)初中英语三大从句详解
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）。 以下是一些基本的从句的语法知识点 A、定语从句专项讲解与训练 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. 先行词定语从句 在所有的从句中，算定语从句最难掌握，因为汉语里没有定语从句，汉语里只有定语，而且总是放在名词之前来修饰名词。 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： 格 先行词主格宾格所有格 人who whom whose 物which which whose of which 人、物that that — （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。 I will never forget the teacher who taught us chemistry in the first year of my senior middle school. 我将永远不会忘记在高一时教我们化学的那位老师。 Anyone who wants to apply for this job must send us the resume by email first. 想应聘这个职位的任何人都必须先通过电子邮件向我们发送简历。 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。例如： 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？ This is the student whom my father taught ten years ago. 这是我爸爸十年前教的学生。 The girl who I saw is called Mary. 我见到的那个女孩名叫玛丽。（在非正式英语中，主格who代替了宾格whom，亦可省略） 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。 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
