说到非限定性定语从句的讲解，还要分成不同的部分，首先大家要知道就得就是该从句的作用是什么。其实它在句子中是一个独立的成分，不会受到主句的限制，把从句去掉之后，主句仍然是成立的。这也是为什么它会叫做非限定性定语从句。
其次，大家要了解该从句的形式：
非限制性定语从句与先行词以及主句之间的关系不甚紧密，因而通常要用逗号与主句分隔开。例如：
Have you seen the film Titanic, whose leading actor is world famous?
你看过“泰坦尼克号”这部电影吗?它的男主演可是世界闻名的。
My friend, who has served on the International Olympic Committee all his l ife, is retiring next month.
我有位朋友，他一辈子服务于国际奥林匹克委员会，下个月就要退休了。
下面就是关于该从句不同类型的介绍：
(1) who引导的非限制性定语从句Our guide，who was a French Canadian，was an excellent cook.我们的向导，一个法裔加拿大人，擅长于烹调。My ga rdener，who is very pessimistic，says that there will be no apples this year.我家的园丁非常悲观，他说今年将不结苹果。(2) whom引导的非限制性定语从句关系代词whom用于指人，在句中作动词宾语和介词宾语，作介词宾语时，介词可位于句末。如：Peter, whom you met in London, is now back in Pari s.彼得现在回巴黎了，你在伦敦见过他。Mr Smith，from whom I have learn ed a lot，is a famous scientist.史密斯先生是一位著名的科学家，我从他那儿学了许多东西。(3) whose引导的非限制性定语从句whose是关系代词who 的所有格形式，在从句中作定语。whose通常指人，也可指动物或无生命的事物。如：The boy, whose father is an engineer, studies very hard.那位小男孩学习很努力，他的父亲是位工程师。Above the trees are the mountains whos e 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。The play，whose style is rigidly form al，is typical of the period.这剧本是那个时期的典型作品，风格拘谨刻板。(4) which引导的非限制性定语从句关系代词which在非限制性定语从句中所指代和修饰的可以是主句中的名词、形容词、短语、其他从句或整个主句，在从句中作主语、动词宾语、介词宾语或表语。①which指代主句中的名词，被指代的名词包括表示物、婴儿或动物的名词、表示单数意义的集体名词以及
表示职业、品格等的名词。如：These apple trees，which I planted three yea rs ago，have not borne any fruit.这些苹果树是我三年前栽的，还没有结过果实。She is an artist，which I am not.她是一位艺术家，而我不是。Water，w hich is a clear liquid，has many uses.水是一种清澈的液体，有许多用途。Th e two policemen were completely trusted，which in fact they were.那两个警察完全受到信任，事实上，也真是如此。②which指代主句中的形容词。如：She was very patient towards the children，which her husband seldom was.她对孩子们很耐心，她丈夫却很少这样。She is always careeless，which we should not be. 她总是马虎大意，我们可不应该这样。③which指代主句中的某个从句。如：He said that he had never seen her before，which was not t rue.他说以前从没见过她，这不是真的。④which指代整个主句。如：In the presence of so many people he was little tense, which was understandable.
在那么多人面前他有点紧张，这是可以理解的。He may have acute appendic itis，in which case he will have to be operated on.他可能得了急性盲肠炎，如果是这样，他就得动手术。When deeply absorbed in work，which he ofte n was，he would forget all about eating and sleeping. 他经常聚精会神地工作，这时他会废寝忘食。(5) when引导的非限制性定语从句关系副词when在非限制性定语从句中作时间状语，指代主句中表示时间的词语。如：He will put off the picnic until May 1st, when he will be free.他将把郊游推迟到5
月1号，那时他将有空。(6) where引导的非限制性定语从句关系副词where 在非限制性定语从句中作地点状语，指代主句中表示地点的词语。如：They went to London，where they lived for six months.他们去了伦敦，在那儿呆了六个月的时间。They reached there yesterday, where a negotiation of sale wi ll be held.他们昨天抵达那里, 有一个关于销售的谈判在那儿举行。(7) as引导的非限制性定语从句as引出非限定性定语从句时，代替整个主句，对其进行说明但通常用于像as we all know, as it is know, as is know to all, as it is, as is said above, as always mentioned above, as is usual, as is often the c ase, as is reported in the newspaper等句式中。as在非限定性定语从句中作主语、表语或宾语，且引出的从句位置比较灵活，可位于句首或句末，也可置于主句中间。通常均由逗号将其与主句隔开。as有“正如……，就像……”之意。如：As it known to the United States, Mark Twain is a great American wr iter.美国人都知道，马克?吐温是一位伟大的美国作家。(as在从句中作主语)He
forgot to bring his pen with him, as was often the case. 他忘了带笔，这是常事。(as在从句中作主语)He is absorbed in work, as he often was. 他正在全神贯注地工作，他过去经常这样。(as在从句中作表语)Boy as he was，he was chosen king. 他虽是孩子，却被选为国王。(as在从句中作表语)as we a ll know, the earth is round.众所周知，地球是圆的。(as在从句中作宾语)The two brothers were satisfied with this decision，as was agreed beforehand.两兄弟对此决定都满意，这项决定在事前都已得到他们的同意。(as在从句中作主语)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。(as在从句中作宾语)(8)“介词+关系代词”引导的非限制性定语从句在介词后引导非限制性定语从句。关系代词which有时并不代表主句中某一确定的词，而是概括整个主句的意思。介词的选择取决于它与先行词的搭配或与从句中谓语动词的搭配。They were short of sticks to make frames for the climbing vines，without which the yield would be halved. 他们缺搭葡萄架的杆儿，没有它们产量会减少一半。They thanked Tom，witho ut whose support they would not have succeeded.这些邻居是北京来的，昨天我被介绍同他们认识了。(9)“名词/代词+of+which / whom”引导的非限制性定语从句It now has 20，000 hectares of land，more than two-thirds of whic h are under cultivation. 现在它拥有两万公顷土地，其中三分之二之多已经耕种。Light is the fast thing in the world, the speed of which is 300.000 kilo meteThere are 30 chairs in the small hall, most of which are new.大厅里有三十把椅子，绝大部分是新的。The textile mill has over 8，000 workers an d staff，eighty per cent of whom are women. 这家纺织厂有8千多职工，女职工占百分之八十。
除此之外大家还要注意一些非限制性定语从句引导词的特殊情况：
1.非限制性定语从句不可用that引导，在非限制性定语从句中用who(作主语) / whom(作宾语)指人，用which(作主语/ 宾语)指物，用whose作定语(指人/ 物)。例如：
The famous basketball star, who tried to make a comeback, attracted a lot o f attention.
这位试图打反击的著名篮球明星吸引了众人的关注。The film, whose director is an old man, is very instructive.
这部电影很有教育意义，它的导演是位老人。
2.关系代词在非限制性定语从句中作宾语时不可省略，若指人时，只用whom，不用who。例如：
York, which I visited last year, is a nice old city.
我去年访问过的约克是个古老而美丽的城市。
Please give the book to Jessica, whom we met in the hall just now.
请把这本书交给杰西卡，就是刚才我们在大厅里遇到的那位。
3.非限制性定语从句不可用why引导，需用for which替代why。例如：None of us accepted the reason he explained, for which he was absent.
我们没有一个人接受他所解释的缺席的理由。
ones怎么用，做题技巧有哪些关于one和ones的用法其实并不是特别复杂，但是需要大家做题的时候细心一点，虽然说ones只比one多了一个s，但是用法上的区别却很大。大家可以用最简单的办法去理解，加s之后就变成了复数了的形式，事实上ones就是one的复数形式。但是很多同学就有了这样的疑问，ones怎么用?这也是很多人都很好奇的一个问题，针对ones怎么用这个问题，小编给大家做出了如下的总结：
one
1)代替上文中出现过的单数可数名词，表泛指(同类但不是同一)前面可以有冠词或形容词，也可以有this或that或another，但前不能有物主代词：
e.g.:I have lost my pen.I’m going to buy one.I prefer this one to that one.
比较：
I’m looking for a flat. I’d like a small one with a garden.
I’m looking for a flat. I’d like one with a garden.
(不能说：... a one with a garden.)
2)作为不定人称代词, 可泛指“任何一个人”，有one's 和oneself形式。多用于正式文体，口语中也可用he/his代替第二个one/one's.
e.g.:
One has to take care of oneself and one's family if he can.
One shouldn't hesitate to correct his/one's mistakes.
If one wants to see the ruins, he must find his own guide.
(如果一个人想看那废墟, 他必须找自己的向导。)
ones
ones是one的复数形式，常用来代替复数可数名词，表泛指，前面不用物主代词修饰，也不用these或those来直接修饰，除非ones前面有形容词：
e.g.:
I have a new coat and several old ones.
These yellow waistcoats are so small. I want those green ones.
one/ones用来代替前面提到过的可数名词，one指代单数, ones指代复数，所代替的是同名异物，表示泛指，可有前置定语或后置定语，也可单独使用，特指时必须加the，用the one/ones 。

定语从句专项讲解与练习 定语从句的定义：从句作定语，修饰名词、代词，这样的从句叫定语从句。 定语从句所修饰的词叫先行词。定语从句作定语放在先行词的前面。 如果要表达:我喜欢那个漂亮的女孩。I love the pretty girl. 如果要表达：那个喜欢我的女孩。只能借助于定语从句the girl who loves me. 其中the girl即为定语从句的先行词，而who即为定语从句的关系词。 指人：who、whom 关系代词指物：which、as （作主宾表）指人和物:that,whose 关系词表时间：when 关系副词表地点：where （作状）表原因：why 1、who 指人，who在从句中当主语。 He who has not reached the Great Wall isn’t a true man. 不到长城非好汉。 The teacher ___________spoke at the meeting just now is having a rest in his office. 中文意思：____________________________________________________________________ ?作主语时不能省略，作宾语时可省略。 2、whom 指人，是who的宾格形式，在从句中作宾语，前面没有介词时，可用who/that来代替，也可省略。The girl ___________________ I like isn’t here now. 中文意思：____________________________________________________________________ The doctor with ________________she went to the United States last month is very famous. 中文意思：____________________________________________________________________ The person ___________________ you met yesterday is our Chinese teacher. 中文意思：____________________________________________________________________ 3、whose 指“谁的”，或“某物的”，在从句中作修饰词。 whose和它所修饰的名词在定语从句中可作主语及动词或介词的宾语。 The girl ___________father is a doctor is our classmate. You’re the only one ____________ advice he might listen to. 中文意思：____________________________________________________________________ I’d like a room _______________window looks out over the sea. 中文意思：____________________________________________________________________ 4、that 在从句中作主语或宾语，既可以指人又可以指物；作宾语时可以省略。 She is the very person (that) I want to see at once. 中文意思：____________________________________________________________________ A plane is a machine_____________ can fly. 中文意思：____________________________________________________________________

Many people, some of whom are not overweight at all, are always going on diets or taking weight-loss pills, which are often dangerous. _____________________________________________________________________ 结论：以上三句是非限制性定语从句。 非限制性定语从句是对先行词起补充和附加说明的定语从句。通常用逗号与先行词隔开，可以修饰主句中的某个名词，也可以修饰整个主句。若省略掉非限制性定语从句，也不会影响句意的完整性。
教学过程 一、复习预习 定语从句是由关系代词或关系副词引导的从句，其作用是作定语修饰主句的某个名词性成分，相当于形容词，所以又称为形容词性从句，一般紧跟在它所修饰的先行词后面。 定语从句又分为限制性定语从句和非限制性定语从句。限制性定语从句对被修饰的先行词有限定制约作用，使该词的含义更具体，更明确。限制性定语从句不能被省略，否则句意就不完整。非限制性定语从句与先行词关系不十分密切，只是对其作一些附加说明，不起限定制约作用。如果将非限制性定语从句省去，主句的意义仍然完整。本节我们着重研究限定性定语从句。 二、知识讲解 非限制性定语从句：从句和先行词关系不密切，去掉定从句，意思仍然完整。形式上用逗号隔开，不能that用引导。 e.g. Tom’s father, who is over sixty, still works hard day and night.（who引导非限 制性定语从句，整个句子可分成两句来翻译） 考点/易错点1 非限定性定语从句中which和as均可使用，一般情况下，逗号后which表示预料之外的事情，而逗号后的as则表示预料之内的事情，e.g. He didn’t come, which surprised u s.他没有来，我们非常吃惊； He didn’t come, as we had expected.他没有来，正如我们所料。 考点/易错点2 which可以在特殊定语从句中作定语，修饰fact, matter, thing 等名词。这些名词代表先行成
分表达的意义，有时将其略去句义仍然完整。as不能作定语。如： I was told to go not by train but bus, which advice I followed. 考点/易错点3 同时注意一个问题，限定性和非限定性定语从句在语义上有时略有差别： There are 5 people, who were injured in the accident. （表示共5个人） There are 5 people who were injured in the accident. （表示人很多，但受伤的只有5个） He didn’t wear clothes which will distinguish him from others. 他不穿那些会把他和别人分开的衣服。（他不穿奇装异服） He didn’t wear clothes,which will distinguish him from others. 他不穿衣服，这把他和别人分开。 造成这样歧义的原因就在于逗号的which课表示前文整句话。 考点/易错点4 as引导定语从句时的用法 ①as引导限制性定语从句通常用于the same … as, such … as结构中。 e.g. I want the same shirt as my friend’s. 我要一件跟我朋友一样的衬衫。 Such machines as are used in our workshop are made in China. 我们车间使用的这种机器是中国制造的。 ②as引导非限制性定语从句既可放在主句之前，也可放在主句之后，用来修饰整个句子。通常用下列句型：as is known to all, as is said, as is reported, as is announced, as we all know, as I expect 等。 e.g. As I expected, he got the first place again in this mid-term examination. 正如我所预料的那样，他在这次期中考试中又获得了第一名。 3）as 引导非限制性定语从句时与which的区别 ①当主句和从句语义一致时，用as；反之，用which来引导非限制性定语从句。 e.g. He made a long speech, as we expected. He made a long speech, which was unexpected. ②当非限制定语从句为否定时，常用which引导。 e.g. Tom drinks a lot every day, which his wife doesn’t like at all. 三、例题精析 【例题1】 【题干】___________ is known to everybody, the noon travels around the earth once every month.(NMET 2001) A.It B.As C.That D.What 解析：答案为B。本题考查as引导的非限制定语从句。as作“正如……”解时，引导的非限制性定语从句来修饰整个句子。当as在从句中作主语时，常用于下列短语：as is known、as is said、as is reported、as is announced等。要注意掌握作关系代词引导定语从句的用法。 【答案】B 【解析】
限制性定语从句与非限制性定语从句 2．关系代词which与as引导非限制性定语从句的区别。 （1）which与as都可以引导非限制性定语从句，which引导定语从句要置于先行词后面，而as引导的定语从句位置相对灵活，可放在句首，也可以放在句后 eg.正像他所意识到的那样，我对他非常有用 As he realized, I was very useful to him. 空气，众所周知，是一种气体 Air, as we know, is a gas. 他是个外国人，正像我从他口音判断的那样。 He was a foreigner, as I know form his accent. 他又来晚了，这一点使老板很生气 He came late again, which made his boss angry. (2)当定语从句位于主句后面，纯粹表示主句所述的内容，往往用which；当定语从句中有“如同……那样”的含义时，用as比用which更常见。 Eg.妈妈老把我当成小孩对待，让我无法忍受 Mummy always treats me just like a baby, which I can’t bear. 事与愿违，这是常有的事 Things will turn out contrary to on e’s wishes, as is often the case. (3)“介词+关系代词”结构的定语从句，必须用which,不能用as. Eg.我们周围有很多氧气，没有他们我们无法生存 There is a great deal of oxygen around us, without which we could not live. 3．引导限制性定语从句时which与as的区别 定语从句前面有such, as, the same 时，引导定语从句的关系代词用as,不用which. Eg 所需要的字典有许多都有了
高中英语定语从句讲解及练习 定语从句是高中重点知识，也是高考常考点，大家也不容易掌握，这篇文章主要教你关系代词引导的定语从句 关系副词引导的定语从句判断关系代词与关系副词限制性和非限制性定语从句等内容，有例题讲解定语从句在句中做定语，修饰一个名词或代词，被修饰的名词词组或代词即先行词。定语从句通常出现在先行词之后，由关系词（关系代词或关系副词）引出。 关系代词有：who, whom, whose, that, which等。 关系副词有：when, where, why等。 18.1 关系代词引导的定语从句 关系代词所代替的先行词是人或物的名词或代词，并在句中充当主语、宾语、定语等成分。关系代词在定语从句中作主语时，从句谓语动词的人称和数要和先行词保持一致。 1）who, whom, that 这些词代替的先行词是人的名词或代词，在从句中作主语和宾语。例如： Is he the man who/that wants to see you? 他就是你想见的人吗？（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在句中作宾语） The package （which / that）you are carrying is about to come unwrapped. 你拿的包快散了。（which / that在句中作宾语） 18.2 关系副词引导的定语从句 关系副词可代替的先行词是时间、地点或理由的名词，在从句中作状语。 1）关系副词when, where, why的含义相当于\"介词+ which\"结构，因此常常和\"介词+ which\"结构交替使用。例如： There are occasions when （on which）one must yield.任何人都有不得不屈服的时候。 Beijing is the place where（in which）I was born.北京是我的出生地。 Is this the reason why （for which）he refused our offer?这就是他拒绝我们帮助他的理由吗？ 2）that代替关系副词，可以用于表示时间、地点、方式、理由的名词后取代when, where, why和\"介+which\"引导的定语从句，在口语中that常被省略。例如： His father died the year （that / when / in which）he was born.他父亲在他出生那年逝世了。 He is unlikely to find the place （that / where / in which）he lived forty years ago. 他不大可能找到他四十年前居住过的地方。 18.3 判断关系代词与关系副词 方法一：用关系代词，还是关系副词完全取决于从句中的谓语动词。及物动词后面无宾语，就必须要求用关系代词；而不及物动词则要求用关系副词。例如： This is the mountain village where I stayed last year. 这是我去年呆过的山村。 I'll never forget the days when I worked together with you.我永远不会忘记与你共事的日子。 判断改错： （错）This is the mountain village where I visited last year. （错）I will never forget the days when I spent in the countryside. （对）This is the mountain village （which）I visited last year. （对）I'll never forget the days （which）I spent in the countryside. 习惯上总把表地点或时间的名词与关系副词where, when联系在一起。此两题错在关系词的误用上。 方法二：准确判断先行词在定语从句中的成分（主、谓、宾、定、状），也能正确选择出关系代词/关

教学过程 一、复习预习 1、对上节课课后作业中的问题进行查漏补缺； 2、导入： e.g. She is a beautiful girl. She is a beautiful girl who drives me crazy. 二、知识讲解 （一）定语从句定义
1、定语从句：在复合句中，修饰某个名词或代词的句子（做这个名词或代词的定语）叫定语从句，定语从句一般放在被修饰的名词或代词后面。 2、先行词：被修饰的名词或代词叫做定语从句的先行词。 3、关系词：用来引导定语从句的词叫做关系词。 关系代词的种类： 关系代词：that, which, who, whom, whose, as 关系副词：when, where, why 4、定语从句结构：先行词+关系词+定语从句。 a、There she saw a wall of water that was quickly advancing towards her. b、In Japan, someone who sees another person making the gesture will think it means money. c、Visitors can go on exciting rides where they can feel what it is like to do the things they have seen their heroes do in the movie. d、Oprah Winfrey is a black woman whose rise to fame is an inspiring story. （二）定语从句分类 限定性定语从句：从句对先行词进行必要的描述或说明，对先行词起修饰限定作用，从句与先行词紧密相连，缺少它则句义显得不完整，一般不用逗号隔开。非限定性定语从句：对先行词进行补充说明，解释，它与先行词关系松散，用逗号隔开。 1、The man who gave me this book is T om .(限定性) 2、T om,who is reading a book ,is my classmate (非限定性) （三）关系代词 1、who指人，在定语从句中作主语。 e.g. The man who is sitting under the tree is a German . 2、Whom指人，在句中做宾语，可省略，但在做介词的宾语是只能用whom,不能用who。关系代词前有介词时不能省略。 e.g. I know the girl (whom) the teacher is speaking to . I know the girl to whom the teacher is speaking . 3、whose, 作定语，可指人或物 e.g. Everyone heplps the child whose parents are dead. They are the lazy students whose homework wasn’t handed in . 4、that 指人或物，多指物，作主语（不能省略）或宾语（可省略） e.g. He is the finest comrade that has helped us . This is a plant that grows in the north . 5、which ,指物，在句中做主语（不能省略），或宾语（可省略）。 e.g. This is a plant which grows in the north . ☆常用that不用which的情况 1、当先行词是all, everything, anything, nothing, much, little, none, one等不定代词时，只用that。 歌诀助记：不定代词这路货，全用that准没错。 Pay attention to everything that I do.
定语从句讲解与练习 一．定义：在复合句中修饰某一名词或代词的从句叫定语从句。 二．特点：1.先行词：定语从句所修饰的名词或代词 2. 关联词： 1）引出定语从句，并作从句的一个成分。可作主语、宾语、定语、状语，作宾语可省略。 2）关联词包括关系代词和关系副词。关联词位于先行词和定语从句之间。 关系代词：that, which, who, whom, whose代指先行词。 关系副词：when, where, why作时间状语。 三．基本结构：先行词+关联词+定语从句剩余部分 四．关系代词的用法： 1. that 和which that指人或物，作主语或宾语，作宾语可省略，主语不能。 Which指物，不指人，作主语或宾语，作宾语可省略，主语不能。 His father works in a factory that/which makes TV sets. Who was hurt in the accident that/which happened yesterday? The coat (which/that) I put on the desk is black. 注意：The room in which I live is very big. (在介词后面不能用that) 2.只能用that不能用which引导的定语从句： 1) 先行词被形容词最高级修饰时，定语从句只能用that This is the most interesting story (that) I have ever heard. 2）先行词被序数词修饰时，定语从句只能用that The children like the second lesson that is about “The Football Match”. 3）先行词被the only，the very 或the same等修饰，定语从句只能用that引导。It is the only word (that) I know in the passage.

限制性定语从句与非限制性定语从句的六点区别 区别一：形式不同 限定性定语从句主句和从句之间不用逗号隔开，口语中使用时也不停顿；而非限定性定语从句与主句之间通常有逗号隔开，口语中使用时有停顿。 区别二：功能不同 限定性定语从句用于对先行词的意义进行修饰、限制和识别，如果去掉，就会造成句意不完整或概念不清；而非限定性定语从句用于对先行词起补充说明作用，如果省略，句意仍然清楚、完整。如： People who take physical exercise live longer. 进行体育锻炼的人活得长些。(若把从句去掉句子就失去意义) His daughter, who is in Boston now, is coming home next week. 他女儿现在在波士顿，下星期回来。(若把从句去句子意义仍然完整) 区别三：翻译不同 在翻译定语从句时，一般把限定性定语从句翻译在它所修饰的先行词之前，而把非限定性定语从句与主句分开。如： He is the man whose car was stolen. 他就是汽车被窃的那个人。 I’ve invited Jim, who lives in the next flat. 我邀请了吉姆，他就住在隔壁。 区别四：含义不同 比较下面的两个句子： I have a sister who is a doctor. 我有一个医生的姐姐。(姐姐不止一个) I have a sister, who is a doctor. 我有一个姐姐，她是当医生的。(只有一个姐姐) 区别五：先行词不同 限定性定语从句的先行词只能是名词或代词，而非限定性定语从句的先行词则可以是名词或代词，也可以是短语或句子；另外，当先行词为专有名词或其他具有独一无二性的普通名词时，通常要用非限制性定语从句，而不用限制性定语从句。如： Peter drove too fast, which was dangerous. 彼得开车很快，这是很危险的。(which指drive too fast) He changed his mind, which made me very angry. 他改变了主意，这使我很生气。(which 指整个主句)
定语从句 用来说明主句中某一名词或代词（有时也可说明整个主句或主句中一部分）而起 定语作用的句子叫作定语从句。 一．词引导的定语从句 1. 关系代词用来指代先行词是人或物的名词或代词 句子成分用于限制从句或非限制性从句只用于限制性从句 代替人代替物代替人或物 主语 Who which that 主语 Whom which that 宾语 Whose(=of whom) whose(=of which) 例1：This is the detective who came from London. 例2：The book which I am reading is written by Tomas Hardy. 例3：The desk whose leg is broken is very old. 例4：This is the room that Shakespeare was born in. 2．关系代词的用法 (1) 如果先行词是all, much, anything, something, nothing, everything, little, none等不定代词，关系代词一般只用that，不用which。例如： All the people that are present burst into tears. (2) 如果先等词被形容词最高级以及first, last, any, only, few, much, no, some, very等词修饰，关系代词常用that,不用which, who，或whom。例 如： (3) 非限制性定语从句中，不能用关系代词that,作宾语用的关系代词也不 能省略。例如：
《非限制性定语从句》微课程教学设计 一．教材分析：本节内容为非限制性定语从句，它是定语从句中的一个重要知识点。定语从句在高中阶段是学生学习的热点，同时也为难点。在学习限制性定语从句将为学习非限制性定语从句打下基础，同时，如何区分限制性和非限制性定语从句也成为学生的困扰，那么本节课主要介绍如何区分非限制性定语从句以及它的定义和用法。 二．学生分析：由于我的学生是刚跨入高中的高一新生，语言和语法知识大部分都停留在初中阶段，定语从句的概念对于他们来说是一个新的知识点，而且难度比初中的知识增大了不少。但是由于他们已经学习过了限制性定语从句，所以理解非限制性定语的用法将会比较容易。 三．教学目的 1．知识和技能目的：熟悉和掌握非限制性定语从句的用法 2．情感和价值观目的：提高学生的学习兴趣 3．能力目的：提高学生的理解和阅读能力 四．教学重难点 1 重点：掌握非限制性定语从句的用法 2 难点：学会使用非限制性定语从句，并用它造句。 五．教学过程 Step 1. Lead-in Show two pictures of Peter and Mr. Smith . Let students guess the identity of Peter and Mr.Smith. Step 2.Introduce definition of nonrestrictive attributive clauses. 非限制性定语从句的定义: 非限制性定语从句和限制性定语从句一样，包含了三要素。先行词+关系代词或关系副词+从句。区别在于：非限制性定语从句起补充说明作用，缺少也不会影响全句的理解。在非限制性定语从句前面有逗号隔开。 Our guide, who was a French Canadian, was an excellent teacher.
