定语从句关系代词可用)
定语从句关系代词只用that的四种情况
定语从句关系代词只用that的四种情况定语从句是英语句子的一种形式，用来描述或定义名词。
关系代词在定语从句中充当连接词，将定语从句引入主句中，起到结构完整化的作用。
在定语从句中，关系代词的种类有很多，其中较为特殊的是只用“that”的情况，本文将详细介绍这种情况下的用法及注意点。
一、定义关系代词”that“是用来连接定语从句和主句的重要连词，在英语中十分常见。
它的形式既可以作主语也可以作宾语，常用于定语从句中，引导一个话题在从句中被进一步解释。
二、使用情况在英语定语从句中，that只有在严格的语法环境中词法才是唯一的选择，情况包括以下四种。
1.介词之后：当先行词是介词时，关系代词只能用that。
例如，“the book that I am reading”中的that是引导定语从句的关系代词。
假如在这个句子中，你用which来代替that，那么这个从句仍然可以理解，但这样使用是错误的。
正确：The book that I am reading.错误：The book which I am reading.2.形容词之后：如果形容词修饰名词，其中包含有定语从句，而先行词又在从句里作宾语，就必须使用that。
例如，“This is the man that I saw on TV yesterday”。
正确：This is the man that I saw on TV yesterday.错误：This is the man which I saw on TV yesterday.3.最高级别形容词之后：当最高级别形容词修饰的名词在定语从句中作先行词时，只能用that，而不用which或者who。
例如，“This is the best d ay that I've ever had in my life”。
正确：This is the best day that I've ever hadin my life.错误：This is the best day which I've ever had in my life.4.不定代词之后：不定代词（如something，anything，nothing，everyone，everybody等）以及不定副词（如somewhere，anywhere，nowhere等）后面的定语从句，只能用that。
英语语法：定语从句 六个关系代词
英语语法：定语从句六个关系代词关系代词有六个，听我逐一来说破；六个关系代词是：that/which/ who/ whom/ whose/ as ，注意关系代词在定语从句中做主宾表定语。
which表物人用who,人物都有that顾；先行词是物，关系代词用which，也能够用that;先行词是人，关系代词用who,也能够用that;先行词中既有人，又有物，关系代词只能用that。
例句 1) This is the mountain village (which/ that ) I visited last year.这就是我去年参观的那个山村。
解析：先行词mountain village是物，可用which或that, 因为定语从句中visit后缺宾语，说明which或that应该在定从中做宾语，所以还能够省略。
例句 2）The man(that/whom / who ) you met just now is my friend.你刚刚见到的那个人是我的朋友。
解析：先行词man表人，关系词能够用who/that/whom，因为定语从句中缺宾语，关系代词应该在定语从句中做宾语，所以能够省略；另外，whom是专门用来做宾语用的，而who则仅仅在口语中才用。
例句 3）This magazine belongs to the teacher who(that) teaches us history.这本杂志是我们历史老师的。
解析：先行词teacher是人，关系代词用who或that, 因为在定语从句中做主语，所以不能省略。
例句 4）He talked about the teachers and schools (that) he had visited.他谈到了他所见到的老师和学校。
解析：先行词 the teachers and schools 中既有人又有物，关系代词只能用 that, 又因为that在定语从句中做宾语，所以又能够省略。

英语定语从句关系代词
定语从句关系代词Attributive ClauseRelative PronounThe person who is riding a bike is my friend.The person以上就是定语从句的一种：关系代词引导的定语从句。
定语从句的基本结构：其中关系代词是重点：关系代词可以引导定语从句。
它代表先行词在从句中作一定的句子成分。
可充当从句的主语，宾语或所有格。
但在结构上都要提前到从句句首部分，靠近先行词。
比如上面的例句可以看做是两个单句，然后以关系代词引导进主句，形成了复合句。
关系代词还有指人与指物之分。
常用的关系代词：1，who 指人2，which 指物3，that 人或物都可指4，whom 指人，只能做宾语5，whose 人或物都可指，只能做所有格(从句中的定语)(所有格)1，关系代词可在从句中做主语：Yesterday I helped an old man who/that lost his way. who/that做主语指代人This is a dictionary which/that will help you a lot. which/that做主语指代物2，关系代词可在从句中做宾语：Mr Wang is the man (whom/who/that) you met in the zoo this morning.3, 几乎万能的that即可做主语也可做宾语，既可指人也可指物而且下面的这些特殊情况也必须用that或者作为宾语省略，** 所以在限定性定语从句中，能用that 尽量用that。
1.当先行词为all, much, none, something, nothing, everything, the one, few, little, many, anything等不定代词时。
例如：We should do all that is useful to the people. 我们应该做一切有益于人民的事情。

(the way后接定语的形式之二) That’s the way in which you answered the question. (the way后接定语的形式之三)。
定语从句主要引导代词的用法
定语从句主要引导代词的用法一：that的用法，that是所有关系代词中最常用的，它既可指人也可指物，既可用作主语也可用作宾语。
如：1、This is the photo (that) I took. 这就是我拍的照片。
引导定语从句的关系代词that在此指事，且在定语从句中用作宾语，故可以省略。
2、They live in a house that was built 200 years ago. 他们住在一座两百年前盖的房子里。
引导定语从句的关系代词that在此指物，且在定语从句中用作主语，故不可以省略。
3、The man that I saw told me to come here. 我见到的人让我到这里来。
引导定语从句的关系代词that在此指人，且在定语从句中用作宾语，故可以省略。
二：who / whom的用法关系代词who和whom均只能指人，不能指物;从理论上说，who是主格，在定语从句中用作主语，whom是宾格，在定语从句中用作宾语。
但在实际运用中，除非是直接用作介词后作宾语，否则凡是用宾格whom的地方。
如：1、I met someone who said he knew you. 我碰到一个人，他说认识你。
引导定语从句的关系代词who在此指人，且在定语从句中用作主语，故不可以省略。
2、She is the girl (who, whom) you saw in school. 她就是你在学校见到的那个女孩。
虽然关系代词在定语从句中用作宾语，从理论上说应用whom，但由于在主句中用作主语，故也可以用who，所以也可以省略。
注意，如果关系代词直接在介词后作宾语，不能用who来代替whom如：The girl to whom I spoke is my cousin. 我和她谈话的那个姑娘是我表妹。
句中的whom直接用在介词to的后面作宾语，故不可省略。
三：whose的用法不要以为关系代词whose只用于指人，其实它也可以用于指事物;whose在定语从句中主要用作定语。
定语从句中的关系代词
定语从句中的关系代词在英语语法中，定语从句是一种非常重要的句子结构，能够用于修饰名词或代词，并且通常使用关系代词来引导。

常见的关系代词包括that、which、who、whom、whose等。
它们在句子中起到连接先行词和定语从句的作用，同时也充当着从句中某个成分的角色。

定语从句基本知识归纳
定语从句定语从句归纳1（基本知识）引导定语从句的词叫作关系代词或关系副词。
关系代词有who、whom、whose、that、which、as等;关系副词有when、where、why等。
它们具有三个功能:1. 连接主句和从句;2. 指代先行词;3. 在从句中充当一种成分。
一、关系代词的用法关系代词的选用:第一,取决于它指代的是人还是物,指代人时可用who、whom、that或as, 指代物时用that、which或as;第二,取决于它在从句中充当的成分,关系代词在从句中可充当主语、宾语、定语等。
指人的who和whom有格的区别:who在从句中作主语(在非正式说法中也可作宾语),whom在从句中只能作宾语,不能作主语,也可以省略。
关系代词whose一般指人,表示"该人的",也可指物,表示"该物的",在从句中作定语。
如: Is this the factory that you visited the other day?The wolves hid themselves in the places that couldn’t be found.That tree, whose branches are almost bare, is very old.I have bought the same dress as she is wearing.The girl who is singing an English song in the next room is Tom’s sister.Didn’t you see the man whom I nodded to just now?二、"介词+关系代词"引导的定语从句关系代词whom, which在定语从句中作介词的宾语时,可以跟介词一起放在主句和从句之间;当先行词指人时,介词后的关系代词用whom, 其余用which,这时的关系代词不能省略; 有时为了使关系代词紧跟它所修饰的先行词,也可以把介词放在从句中有关动词的后面,这时的which可用that替换。

一、定语从句的引导词有关系代词who,whom,whose,which,that,as；关系副词when,wh ere,why.定语从句中引导词的选用主要看先行词在定语从句中作什么成分或者是定语从句中缺什么成分.1．定语从句中缺主语,修饰人时用who ／that,修饰物时用which ／that引导.如：Is this the factory which ／that makes TV sets?The man who ／that visited our school is from Australia．2．从句中缺宾语,修饰人时用 who ／whom ／that或省略引导词；修饰物时用which ／that或省略引导词.如：Gone are the days which ／that we spent together in the village．He is the man who ／whom ／that I think to be worthy of our praise．3．从句中缺时间状语,用when或介词＋which引导.如：The day finally came when ／on which I was given a job．We'll put off the outing until next week,when we won't be so busy．4．从句中缺地点状语,用where或介词＋which引导.如：Please put the letter on the desk where ／on which he can easily find it．5．从句中缺原因状语或先行词是 reason时,引导词用why ／for which ／ that.如：This is the reason why ／for which ／ that he didn't come to the meeting．6．从句中缺定语,人和物都用 whose引导.如：A child whose parents are dead is called an orphan．Please pass me the dictionary whose cover is black．7．当先行词是way时,其定语从句的引导词用in which ／that.如：The way in which ／that he looks at problems is wrong．二、引导词as可引导限制性定语从句,也可引导非限制性定语从句.1．在固定词组the same．．．as,such．．．as中,as引导限制性定语从句.如：He is not such a fool as he looks．I've bought the same dress as she is wearing．2．当先行词是整个主句时,可用 as／which引导非限制性定语从句.引导词as和which的区别在于：①as引导的非限制性定语从句可放于主句前、主句中、主句后,而which引导的非限制性定语从句一般放于主句后或句中.②as常与从句中的know,see,hear,expect等动词连用,也常用于as often happens,as is often the case（常有的事）等句子中；而which一般不用于以上情况.③as有“正如”的含义,which没有此含义.如：As is well known,Shanghai is a big city．Some of the roads were flooded,which made our journey more difficult．三、关系代词who,whom,whose,which和as能引导非限制性定语从句,而that不能；非限制性定语从句中即使缺宾语,引导词也不能省略；关系副词when,where能引导非限制性定语从句,而why不能.如：Abraham Lincoln,who led the United States through the Civil War years,was shot on April 14,1865．四、先行词是物时,其引导词可用which也可用that,通常情况下二者可互换,但在有些情况下不能.1．用which不用that引导定语从句的三种情况：①非限制性定语从句用which,不用that引导.如：Football,which is a very interesting game,is played all over the world．②先行词为that时,为了避免重复,定语从句用which不用that引导.如：That which you borrowed from me wasn't a real diamond necklace．③介词后用which不用that引导.如：The method with which you solved the problem is very good．2．用that不用which的七种情况：①先行词前有形容词最高级或序数词修饰时,用 that不用which引导.如：This is the best place that I have ever visited．The second question that is asked is why we don't fall off the earth．②先行词为little,much,all,none,few,（the）one,something,everything,nothing,anythin g等不定代词时,用that引导.如：There is nothing in the world that can frighten him．③先行词既有指人的名词又有指物的名词时,用 that引导.如：He told us about the people and the cities that he had visited．④先行词前有any,all,no,few,every,some,little,much,（the）very,（the）only,（the）l ast等词修饰时,用 that引导.如：This is the very coat that I need．Is oxygen the only gas that helps fire burn?⑤先行词为which时,为了避免重复,用that引导.如：Which is the book that you bought yesterday?⑥先行词在从句中作表语时,常用that引导.如：Shanghai is no longer the city that it used to be in the 1930's．⑦当主句是There be．．．句型时,用that引导.There are two tickets for the film that are for you two．五、在“one of＋复数名词＋定语从句”结构中,从句的谓语动词应与复数名词保持一致；当one前有the only修饰时,从句的谓语动词应与the only one保持一致.如：He was one of the students who were late for class．He was the only one of the students who was late for class．六、引导词前有介词或短语介词时,修饰人只能用 whom,修饰物只能用which引导.如： My glasses,without which I was like a blind man,fell to the ground and broke．The man,by whom the wolf was shot,is called Jackson．。
