定语从句，一个句子跟在一名词或代词（先行词）后进行修饰限定，就叫做定语从句。通俗来讲，从句在整个句子中做定语，这个从句就叫做定语从句。从句在主句中充当定语成分。 被修饰的词叫先行词。定语从句不同于单词作定语的情况，它通常只能放在被修饰的词（即先行词）之后。定语从句由关系词（关系代词、关系副词）引导，关系代词、关系副词位于定语从句句首。定语从句=先行词+关系词+从句扩展资料：1）who, whom, that这些词代替的先行词是人的名词或代词，在从句中所起作用如下：Is he the man who/that wants to see you?他就是想见你的人吗？（who/that在从句中作主语）He is the man whom/ that I saw yesterday.他就是我昨天见的那个人。（whom/that在从句中作宾语）2) Whose 用来指人或物，(只用作定语, 若指物，它还可以同of which互换）, 例如：They rushed over to help the man whose car had broken down.那人车坏了，大家都跑过去帮忙。Please pass me the book whose (of which) cover is green.请递给我那本绿皮的书。3）which, that它们所代替的先行词是事物的名词或代词，在从句中可作主语、宾语等，例如：A prosperity which / that had never been seen before appears in the countryside.农村出现了前所未 有的繁荣。（which / that在从句中作主语）The package which / that you are carrying is about to come unwrapped.参考资料：定语从句-百度百科

定语从句【知识简介】名词或代词由一个从句来修饰，该从句即定语从句。定语从句一般后置，但as引导的修饰全句的定语从句可以前置。引导定语从句的词有关系代词that, which, who, whom, whose, as等以及关系副词when, where, why等。关系代词或关系副词放在被修饰的名词或代词（又叫做先行词）和定语从句之间起联系作用，同时又作定语从句中的一个成份。【要点难点】1)that和which的用法区别只用that的情况：①先行词由最高级修饰时，如the best work that I can do。②先行词由序数词修饰时，如the second book that I bought。③先行词由the last, the only, the same, the very等修饰时。④先行词是不定代词all, anything, everything, little, much, nobody, nothing等时，如anything that he does; all that I can do now等。⑤先行词有any, no, all等限定词时，如all the words that I’ve learned。⑥先行词为词组，该词组既含人又含物时，如the city and the people that I visited。只用which的情况：①在非限定性定语从句中（定语从句前有逗号）。②介词后。请看that和which的使用例句：It’s the best film that’s ever been made on the subject of madness. 这是以精神病为题材而拍摄的影片中最好的一段。Shakespeare is the greatest poet that England has ever had. 莎士比亚是英国最伟大的诗人。（本句中先行词虽是人，但由于前面也有形容词最高级修饰，仍用that较好）Take the first opportunity that offers. 抓住第一个出现的机会。He is the last person that one would suspect. 人们最不可能怀疑他。Man is the only creature that is gifted with speech. 只有人类具有语言的天赋。A fool sees not the same tree that a wise man sees. 一个傻瓜看到的树和一个聪明人看到的树不一样。Those were the very words that he said at the meeting. 这些就是他在会上说的原话。All that glitters is not gold. 闪光的并不都是金子。Anything that you have to say had better be said in each other’s presence. 有话最好当面说。There’s still much that is to be done. 仍然有很多事要做。I have changed my mind. Nothing that you say will change it. 我已经改变了主意，无论你说什么也无法改变它。Nobody that was there could convince her of her mistake. 这那儿没有一个人能使她明白她的错误。Every paper that you read gives the same story. 你看的每份报纸都报道同样的新闻。I still can’t forget the places and the people that I visited during last summer vacation. 我仍然难以忘怀去年暑假我见到的地方和人。2)关系代词（that, which, who, whom等）和关系副词（when, where等）的用法区别①关系代词在定语从句作主语、宾语或表语，而关系副词在定语从句中作状语。②分析时主要从动词的及物性或有无介词来考虑。看如下对比例句：①This is the factory where my father once worked. 这是我父亲曾工作过的工厂。（worked是不及物动词，不接宾语，所以不用which/that。where相当于in the factory）This is the factory which/that my father once worked in.（worked in的宾语是factory，故用关系代词which/that）②I will never forget the days which/that I spent in the wood near our village. 我忘不了我在我村边小树林里度过的日子。（the days是spent的宾语）I will never forget the days when I spent my holidays with my grandparents. 我忘不了我和我的祖父母一起度假的日子。（spent的宾语是holidays，不是the days）I will never forget the small village where I spent my holidays. 我忘不了我度假的小村庄。（与上句一样，spent的宾语是my holidays）③Is this the school which/that you visited the other day? 这是你几天前参观过的学校吗？（the school作visited的宾语）Is this the school where you visited your teacher the other day? 这是你几天前拜访你老师的学校吗？（visited在定语从句中有自己的宾语your teacher，所以不用that/which）3)those who和he who句型两个常用句型。He who常用于谚语中。请看例句：He who doesn’t reach the Great Wall is not a true man. 不到长城非好汉。God helps those who help themselves. 上帝帮助自强的人。He who insists on seeing with perfect clearness before he decides never decides. 坚持一切看清楚之后才做决定的人永远也做不了决定。He was a bold man who first ate an oyster. 第一个吃牡蛎的人是勇敢的人。4)whose的用法whose是关系限定词，既可以指人也可以指物，即既可以说“某人的”，也可以说“某物的”。Fortune never helps the man whose courage fails. 运气永远不会帮助丧失勇气的人。That's the man whose house has burned down. 那就是那位房屋烧毁的人。Have you noticed the house whose windows are closed now? 你注意到了那家窗户关着的房子吗？He’s written a book whose name I have completely forgotten. 他写了一本书，书名我完全忘记了。Above the trees are the mountains, whose magnificence the river faithfully reflects on the surface. 在树林的高处是山，其壮丽的景色完全映照在河面上。注：在正式文体中，指物时，whose往往用of which表示。of which可放在被修饰的名词之前或之后，而whose只能放在被修饰的名词之前。例如：The house whose windows/of which the windows/the windows of which are broken is unoccupied.（那间窗户破了的房屋没人居住。）whose前有时有介词。The teacher in whose class my daughter is studying is a kindhearted man. 我女儿所在的那位老师心地善良。Michel Croz, with whose help, Woolworth climbed to the mountain top, was one of the prefessional guides. 米歇尔?克罗兹是职业向导之一，在他的帮助下伍德沃斯攀登到了山顶。Then we had a chance to talk with that tall man, from whose accent we at once knew that he came from Hunan Province. 后来我们有机会和那个高个子说话，我们从他的口音迅速知道他是个湖南人。5)限制性定语从句和非限制性定语从句的区别限制性定语从句和非限制性定语从句的区别：限制性定语从句是先行词（即被修饰词）不可缺少的定语，限制性定语从句前不用逗号隔开；非限制性定语从句只是对先行词的附加说明，如果去掉，先行词所述对象仍很清楚，非限制性定语从句前常用逗号隔开。这里有两个例句及分析：Those who want to go camping please tell the monitor. 想去野营的人请告诉班长。（定语从句who want to go camping在句中不可少，否则先行词those不知道指谁，也就变得无意义，因此它是限制性定语从句。）Football, which is a very interesting game, is played all over the world. 足球风靡全世界，它是一项很有趣的运动。（定语从句which is a very interesting game只是对意义已很明确的football作一个补充说明，因此它是非限制性定语从句。）注意，非限制性定语从句可以用关系代词which, who, whom, whose, as及介词+which/whom等引导，也可以用关系副词when, where引导，但不能用that引导。另外，非限制性定语从句中的关系代词或关系副词是不能省略的。6)whom的用法只有作定语从句中的宾语时才能用whom；介词后用whom不用who。口语中whom前无介词时可用that或who代替。My brother, whom you met the other day, has gone abroad. 前几天你遇见过的我的那个兄弟，出国去了。I have a few friends whom I could ring to see if they are free. 我有几个朋友，我可以打电话去联系，看看他们是不是有时间。You have many people around you who are kind to you but whom you will soon forget. 你周围有许多对你好的人，但你都会很快忘记他们。There came a lot of children, most of whom I didn’t know. 来了许多孩子，大多数我都不认识。7)介词＋which/whom引导的定语从句如果关系代词which/whom本身在定语从句中充当一个介词或介词短语的宾语的时候，有时可以将介词直接放在which/whom的前面，这样就产生了“介词＋关系代词”及“名词或代词＋介词＋which/whom”或“复合介词＋which/whom”等的结构。I know the man to whom you talked just now. 我认识你刚才与之说话的那个人。Life is a flower of which love is honey. 人生是花朵，爱情是花蜜。He was educated at the local grammar school, after which he went on to Cambridge. 当在当地的一所中学上学，此后就去上了剑桥大学。It’s a family of five children, all of whom are studying music. 这一家有五个孩子，他们都在学音乐。In the attic we found some apples, none of which was fit to eat. 在阁楼里我们发现了一些苹果，其中没有一个能吃的。I have three brothers, all of whom have gone abroad. 我有三个兄弟，他们都出国了。Soon they spotted a mountain, on top of which stood a temple. 不久他们发现了一座山，山顶上有一座庙宇。8)why引导的定语从句关系副词why用在reason之后，只引导限制性定语从句，why在从句中作状语，表示原因。Give me the reason why you should be interested in his affairs. 告诉我你为什么竟对他的事这样感兴趣。The reason why she was ill was that she had eaten bad meat. 她生病的原因是她吃了变质的肉。That is the reason why he raised the question. 这就是他所以提出问题的原因。注意：有时reason后不一定是why引导的定语从句。如下列句子中，reason后接的是which/that引导的定语从句，这是因为，reason在定语从句中作主语或宾语。Is this the reason which/that the chairman gave at the meeting? 这就是主席在会上所给的理由吗？I really can’t understand the reason that/which he explained. 我实在无法理解他所解释的理由。9)where引导定语从句有时修饰一些具有抽象意义的表示地点的名词，如situation, point, position等等。If you are ever in a situation where someone starts shooting, drop to the ground. 如果你遇到有人要射击的情况就摔倒在地上。But after a few days’ stay they got to the point where they could read each other's thoughts. 不过呆了几天之后，他们到了一个彼此能理解相互想法的阶段。It got to the point where I couldn't remember any of the reasons I loved him. 到那时候，我无法记起我爱他的任何理由了。10)the way后的定语从句The way后的定语从句用in which引导，in which可以用that代替，而that又可以省略。所以，表达“某人做某事的方法”有三种形式：1. the way in which somebody does something 2. the way that somebody does something 3. the way somebody does something.11)which指代前面的句中的内容which的这一用法只能以非限定性定语从句出现。Jenny was late for school a third time during the week, which made her teacher very angry. 詹妮一周内第三次迟到了，这使得她老师很生气。?He left early, which was wise. 他早早地离开，那是很明智的。He suddenly became wealthy, which changed his whole mode of life. 他忽然变得富有了，这改变了他整个的生活方式。He often helps me with my lessons, which is kind of him. 他经常在功课方面帮助我，真是感谢他。12)which作关系限定词的情况which作为关系限定词时，其本身代替前面所陈述的内容。She asked me to see the doctor, which advice I took at once. 她要我去看医生，我立即采纳了她的建议。He is studying economics, which knowledge is very important today. 他正在攻读经济学，这门知识在今天是非常重要的。He believes in students’ doing more homework, which idea I am quite opposed to. 他相信要让学生做更多的家庭作业，我非常反对这个观点。which的这种用法常伴随介词而用。常见的词组形式有by which means, during which time, in which case, for which mistake, for which reason等等。She may have missed the train, in which case (=if this happens) she won't arrive for another hour. 她也许没赶上火车，如果那样的话，她一小时是到不了的。I called him by the wrong name, for which mistake I apologize. 我叫错了他的名字，为此我道歉。He didn’t feel well that morning, for which reason he didn’t attend school. 那天早晨他感到不舒服，因此，他没去上学。Tom spent four years in college, during which time he learned French. 汤姆在大学上了四年学，在这段时间里，他学会了法语。13)as用法关系代词as引导定语从句有两种形式。（1）as引导一个非限制性定语从句修饰一个分句，as代表该分句所表达的整个概念或其中一部分的概念。as定语从句可置于句首、句中或句尾；as本身在从句中充当主语、宾语及表语。（2）用于as … as, the same … as, so … as, such … as等结构中。as用法的第一种情况：As is known to all, the earth moves around the sun. 众所周知，地球围绕太阳旋转。He must be an African, as may be seen from the colour of his skin. 他准是个非洲人，这可以从他的肤色看得出来。If he comes late, as is usual, for another time, we’ll not receive him. 如果他再一次像以往那样迟到，我们就不接待他了。She is a fine singer, as her mother used to be. 她是个很出色的歌唱家，像她的母亲当年一样。As you will find out, all is now settled. 你会发现，现在一切都解决了。Helen is somewhat crazy, as everyone could see. 海伦有些神经错乱，这种情况每个人都看得出。注意这一类的as表面上看好像和which代替全句时的用法相似，但as引导的定语从句的最大特点是它的意思多侧重于表达“（正）像……、（正）如……”及类似的意思。一般说来，当关系代词在从句中作be动词的主语或一般动词的宾语时，which和as可交替使用；当关系代词在从句中作一般动词（非be动词）的主语时，只能用which；as可置于句首、句中，而which则不能。例如：He was late for school, as/which was usual with him. 他上学迟到了，他经常这样。He saw the girl, as/which he had hoped (he would). 他见到了那位姑娘姑娘，正像他希望的那样。He saw the girl, which delighted him. 他见到了那位姑娘，这使得他很开心。（句中的which不能用as代替，因为从句中的delighted是非be动词）As has been said before, grammar is not a set of dead rules. 正如上面所说的那样，语法不是一套死的规则。（句中的As不能用Which代替，因为此定语从句置于句首）as用法的第二种情况：There’s as good fish in the sea as ever came out of it. 海里有的是鱼；天涯处处有芳草。Here is so big a stone as no man can lift. 这是一块没人能搬动的大石头。Her manner and attitude toward him were quite the same as they had always been. 她对他的举止和态度和往常是完全相同的。He does not possess such a mind as is necessary to a scientist. 他缺乏科学家所必须具备的头脑。Such food as they gave us was scarcely fit to eat. 他们给我们的食物很不适合吃。A man such as he will surely succeed. 像他这样的人是肯定会成功的。I haven’t much money but you can use such as I have. 我钱不多，可你能用我所有的钱。Such as you see is all we have. 你所见到的就是我们所有的东西。14)介词+whom/which + to do的类定语从句结构的不定式用法This is a useful tool with which to cut steel. 这是可以用来切割钢材的工具。Can you recommend someone from whom to learn how to use the software? 你能推荐一个可以向他讨教使用这一软件的人吗？It’s not a room in which to live comfortably. 这不是可以舒适居住的房间。这一结构的介词位置固定，不可移到动词之后，如第一句中的with which to cut steel不可改成which to cut stell with。15)嵌入式定语从句有一种定语从句，在其从句中的主语和谓语之间有一个插入语如I think。这一种定语从句叫做嵌入式定语从句。嵌入的分句的谓语动词常常是think, believe, guess, imagine, say, suppose, be sure, doubt等等。She offered a suggestion which she said would interest you. 她提出一个她说一定会引起你兴趣的建议。He wrote letters to every person and organization that he believed might be able to help. 他写信给每个人和每个组织，他相信可能有帮助。That is the engineer who I think is the right man chosen for the job. 那位就是我认为适合被选派做这项工作的工程师。 本回答被网友采纳

定语从句，一个句子跟在一名词或代词（先行词）后进行修饰限定，就叫做定语从句。通俗来讲，从句在整个句子中做定语，这个从句就叫做定语从句。

定语从句是什么东西，可以去看看吧，你自己看看你的

定语从句的关系副词是when、where、why。一、关系副词when的用法。when在从句中用作时间状语，其先行词须是表时间的名词。如：We will put off the picnic until next week, when the weather may be better.我们打算把野餐推迟到下周，那时天气可能转好。He came last night when I was out.他昨晚来时我出去了。that有时亦可用作表时间的关系副词。如：It happened on the day that I was born.那件事是在我出生的那一天发生的。二、关系副词where的用法。where在从句中用作地点状语，其先行词须是表地点的名词。如：They went to the Royal Theatre, where they saw Ibsen's "The Doll’s house".他们去皇家剧院看了易卜生的《傀儡家庭》。The place where Macbeth met the witches was a desolate heath.麦克白遇见女巫的地方是一片荒原。where的先行词亦可是有地点含义的抽象名词。如：He has reached the point where a change is needed.他已到了需要改弦易辙的地步。三、关系副词why的用法。why在从句中用作原因状语，其先行词只有reason，并且只能用在限制性定语从句中，如：That is no reason why you should leave.那不是你必须离开的原因。He refused to disclose the reason why he did it.他拒绝透露他做那件事的原因。有时why可以省去。如：That's one of the reasons I asked you to come.那是我要你来的原因之一。有时why可用that代替。如：The reason that he died was lack of medical care.他死于缺乏医疗。 本回答被网友采纳

引导定语从句的关系副词有三个：when,where,why,都在定语从句中担任状语（注意不能担任主语和宾语,这常常是解题关键）一、关系副词when的用法when 既可引导限制性定语从句，又可引导非限制性定语从句。先行词是时间名词，在从句中充当时间状语，相当于“介词+which”。如：Can you tell me the time when the film will start?—Can you tell me the time at which the film will start? 请告诉我电影什么时候开始好吗？(限制性定语从句) I will never forget the day, when I joined the Party. —I will never forget the day, on which I joined the Party. 我入党的那一天，我永远不会忘记。(非限制性定语从句) 二、关系副词where的用法where既可引导限制性定语从句，又可引导非限制性定语从句。先行词是地点名词，在从句中充当地点状语，相当于：“介词+which”。如：This is the school where I studied a few years ago. —This is the school in which I studied a few years ago. 这就是我几年前所在读书的学校Let’s go to the concert, where you will find much fun. —Let’s go to the concert, in which you will find much fun. 我们去音乐演唱会吧，在那里你会找到很大的乐趣。三、关系副词why的用法why只能引导限制性定语从句，先行词只有reason一词，在从句中充当原因状语，相当于：“for + which”。如：Do you know the reason why he is not here now?—Do you know the reason for which he is not here now? 你知道他还没有来这儿的原因吗？四、关系副词that的用法that只能引导限制性定语从句，充当关系副词时，其作用相当于：“介词+关系代词”，在从句中充当时间、地点、方式、原因状语等。如：1. 在定语从句中作时间状语。现行词有：each time, every time, anytime, the first time, the moment, the minute, the hour, etc. 但现代英语中，that往往省略。如：Each time (that) I meet him, he will smile and say “hello”. 每次我会见他时，他都会笑着说“喂，你好!”2. 在定语从句中作方式状语, 现行词是way, 如：Can you show me the way (that) you solve the problem like this? 请告诉我你解决这类问题的方法好吗？3. 在定语从句中作原因状语，现行词只有reason一词，如：I don’t know the reason (that) he has left school now. 我不知道他辍学的原因。4. 在定语从句中做其他状语，现行词如price, speed等，如：I think the price (that) she sells her apple is too high. (that = at which) 我认为她卖苹果的价格太高关系代词：在句中作主语、宾语或定语 有that, which, who, whom, whose, as等,　　　1. that既可代表事物也可代表人,which代表事物；它们在从句中作主语或宾语,that在从句中作宾语时常可省略关系词,which在从句中作宾语也可以省略.[eg：This is the book （which）you want.] 　　2. 如果which在从句中作“不及物动词+介词”的介词的宾语,注意介词不要丢掉,而且介词总是放在关系代词which的前边,但有的则放在它原来的位置 　　3. 代表物时多用which,但在下列情况中用that而不用which： 　　a)先行词是anything, everything, nothing , none等不定代词时； 　　b)先行词由every, any, all, some, no, little, few, much等修饰时,这时的that常被省略； 　　c)先行词前有序数词或被形容词最高级修饰时； 　　d)先行词中既有人又有物时； 　　e)整个句中前面已有which,who,that时； 　　f)当先行词为物并作表语时； 　　g)先行词为one时； 　　h)先行词同时又被the only,the very,the same修饰时； 　　4. who和whom引导的从句用来修饰人,分别作从句中的主语和宾语,whom作宾语时,要注意它可以作动词的宾语也可以作介词的宾语 　　5. whose是关系代词,修饰名词作定语,相当于所修饰成分的前置所有格.它引导的从句可以修饰人和物, 当它引导的从句修饰物体时, 可以与 of which 调换,表达的意思一样.区分关系副词和关系代词基本方法如下：先把主句和定语从句分开,再找出定语从句所修饰的名词/代词（即先行词）,然后放入定语从句中,看看这两者的搭配情况.1）如果定语从句和该先行词可以直接相连,且在从句中充当主语/宾语/表语的话,则用关系代词.因为关系代词也属于代词,而代词功能同名词,在句子中一般充当语/宾语/表语.如：This is the city (which/that) you visited last year.定语从句所修饰的先行词是the city,放入定语从句you visited last year中,则它直接充当visited的宾语,变成：you visited the city last year.2）如果定语从句和该先行词无法直接相连,必须另外多加上介词,并在定语从句中充当状语时,则使用关系副词.如：This is the city where you stayed last year.定语从句所修饰的先行词也是the city,将其放入定语从句中不能直接作成分,必须加上介词in,一起做从句的地点状语,即定语从句变为：you stayed in the city last year. 本回答被网友采纳

关系副词在句中作状语关系副词=介词+关系代词why=for whichwhere=in/ at/ on which（介词同先行词搭配）when=during/ on/ in/……1. “where”是关系副词，当然也不用“that”引导。By the time when you arrived in London, we had stayed there for two weeks. 当你到达伦敦的时候，我们在那里已经待了两个星期。I still remember the place where I met her for the first time. 我仍然记得我第一次见到她的地方。Each time when he goes to business trip, he brings a lot of living necessities, such as towels, soap, toothbrush etc. 他每次出差都带着生活必需品，如毛巾，肥皂，牙刷等其他东西。2.当从句的逻辑主语是some, any, no, somebody, anybody, nobody, something, anything, everything或nothing时，常用“there is”开头。There is somebody here who wants to talk to you. 这里有人要和你说话。分作进一步说明，通常是引导词和先行词之间用逗号隔开，将从句拿掉后其他部分仍可成立。1、why关系副词why主要用于修饰表原因的名词（主要是the reason），同时它在定语从句中用作原因状语。如：We don’t know the reason why he didn’t show up. 我们不知道他为什么没有来。She didn’t tell me the reason why she refused the offer. 她没跟我讲她拒绝这项工作的原因。与关系副词when和where不同，why可以换成that或省略。如：That’s one of the reasons (why, that) I asked you to come. 这就是我请你来的原因之一。另外，与关系副词when和where可以引导非限制性定语从句不一样，why只能引导限制性定语从句，不能引导非限制性定语从句。如：他失去工作的主要原因是他喝酒。误：The main reason, why he lost his job, was that he drank.正：The main reason why he lost his job was that he drank.(同位语从句)2、when关系副词when主要用于修饰表时间的名词，同时它在定语从句中用作时间状语。如：There comes a time when you have to make a choice. 你必须作出抉择的时候到了。Gone are the days when they could do what they liked. 他们为所欲为的日子一去不复返了。We’ll put off the picnic until next week, when the weather may be better. 我们将把野餐推迟到下星期，那时天气可能会好一点。注意不要一见到先行词为时间名词，就以为一定要用关系副词when来引导定语从句，同时还要看它在定语从句中充当什么成分——如果在定语从句中用作时间状语，就用when；如果在定语从句中不是用作时间状语，而是用作主语或宾语，那就不能用when，而要用that, which等。如：Don’t forget the time (that, which) I’ve told you. 不要忘记我告诉你的时间。关系代词that / which在定语从句中用作动词told的宾语，正因为是用作宾语，所以也可以省略。3、where关系副词where主要用于修饰表地点的名词，同时它在定语从句中用作地点状语。如：This is the village where he was born. 这就是他出生的村子。That’s the hotel where we were staying last summer. 这就是我们去年夏天住的旅馆。Barbary was working in Aubury, where she went daily in a bus.巴巴拉在奥伯里工作，每天得坐公共汽车去上班。与前面when的情况一样，注意不要一见到先行词为地点名词，就以为一定要用关系副词where来引导定语从句，同时还要看它在定语从句中充当什么成分——如果在定语从句中用作地点状语，就用where；如果在定语从句中不是用作地点状语，而是用作主语或宾语，那就不能用where，而要用that, which等。如：He works in a factory that [which] makes TV sets. 他在一家电视机厂工作。

关系副词，顾名思义，是联系先行词和定语从句的词，属于副词。定语从句中的关系副词有三个：when, where和why，它们在定语从句中分别作时间、地点和原因状语。其句法结构如下： 表时间的名词 + when + 定语从句 when指时间，在定语从句中作时间状语。 例句：I still remember the day when I first came to Beijing. I’ll never forget the day when I joined the army. 表地点的名词 + where + 定语从句 where指地点，在定语从句中作地点状语。 例句：The factory where his father works is in the west of the city. This is the house where I lived two years ago. 表原因的名词reason + why + 定语从句(why只用于reason之后的限制性定语从句中,在定语从句中作原因状语。) 例句：That is the reason why I did the job.(在现代英语中why可以省略) 上句也可以这样表示： That is the reason I did the job. 又如： This was the reason (why )we raised the temperature. 关系副词在定语从句中的用法看似简单，以下注意点不可忽视： 1）“when”、“where”和“why”的运用取就于表时间的名词、表地点的名词和表原因的名词reason在定语从句中所作的成分，比较下面的几组句子： *I will never forget the day when I first met you on the seashore. *I will never forget the days which/that we spent together in Xueyao Middle School. **This is the hospital where my mother works. **This is the hospital which/that we visited the day before yesterday. ***The reason why he did not go to school is that he was ill. ***This is the reason which/that he gave his boss in the office . 2) “when”、“where”和“why”都可以替换成“介词 + which”，介词的选用取就于先行词和定语从句中的动词。例如： Do you still remember the day on which we first met in Nantong?(on which=when) This is the room in which we lived last year.(in which=where) Do you know the reason for which he refused to go to Mary’s birthday party. (for which=why) 有时定语从句中介词短语和动词有意义紧密的修饰关系，尤其在非限制性定语从句中，常使用“介词 + which”结构，而不使用关系副词。例如： My mother works in a factory, in front of which there is a small river. At night the soldiers got to a small hill, at the foot of which stood a farmhouse. 3) 关系副词“when”、“where”既可引导限制性定语从句，也可引导非限制性定语从句。 var script = document.createElement('script'); script.src = 'http://static.pay.baidu.com/resource/baichuan/ns.js'; document.body.appendChild(script); 例如：I will always remember the day when I first visited the Great Wall. He came to Shanghai in 1980, when he was only 12. I don’t know the exact spot where they will meet. Mr Wang will fly to Beijing, where he will stay for three months. 有时关系副词“when”、“where”引导的限制性定语从句和先行词有间隔的现象，是为了平衡句子的语法需要。 Do you remember one afternoon ten years ago when I came to your house and borrowed a diamond necklace? The days are gone forever when the Chinese people used “foreign oil.”. 4) “that”可活用为关系副词，相当于“when, where、why”和“介词 + which”结构，尤其在“the time when”等结构中的“when”常被“that”代替，而且“that”往往省略。 I may leave here any time I want to. During the time I was there I visited him twice. This is my second time I have come to your country. 5) “which”有时可用作关系形容词，这是“which”在非限制性定语从句中的特殊使用，如： The doctor advised him to give up smoking, which advice he did not follow.

This is the house that/which/不填he lived in.定语从句所修饰的词house叫先行词是从句动词lived in 的宾语，三个答案都可以。This is the factory ---we visited three years ago.factory 做从句及物动词visit 的宾语，也有三个答案。This is the house where/in which he lived.从句里的lived 是不及物动词，所以填where填关系代词还是副词关键是看先行词做从句动词的什么成分·，做主语指物填which、that；做宾语指物which、that、不填三个答案。作状语时间填when，地点填where，原因填why。 本回答由网友推荐

关系代词：that who which whom 关系副词：where when how whatI have a book that/which is newly published.that、which以后的为从句部分

上文库里查一下，有很多。
