?非限制性定语从句的概念：
非限制性定语是对被修饰名词或代词的附加说明，它不是必需的，如果去掉，也不会影响句子的意思，它与被修饰名词之间通常用逗号分开。
如：The travellers, knowing about the floods, took another road. 游客们知道发了大水，都改道走了。
The boys, wanting to play football, were disappointed when it rained. 那些男孩子想踢足球，因为下雨感到失望。
?非限制性定语从句用法：
1、引导非限定性定语从句时，只能用which(不用that)。
例如：Heat is another form of energy, which is as important as other kinds of energy.
热是另一种形式的能量，与其他形式的能量一样重要。（从句表补充说明，而且关系代词which不能换成that。）
2、引导非限定性定语从句的which可以指代前面的先行词,也可以指前面整个句子的含义。
例如：That Peter will marry Alice, which has not been announced yet, has spread around.
彼特要娶爱丽斯这件事还没宣布，却已传得沸沸扬扬。（句子中的which指“彼特要娶爱丽斯”这整个句子的意思。）
3、除which外，还可用when，where，who等关系代、副词引导非限定性定语从句。
例如：After graduation, I decided to stay in Chongqing, where I spent my childhood and four years of college life.
毕业后，我决定留在重庆，在那里我曾度过了我的童年和四年大学生活。
Albert Einstein left Germany for the United States during World WarII, when Jews were badly treated in Germany.
第二次世界大战期间，爱因斯坦离开德国去了美国，那时犹太人在德国受到不好的对待。
4、在限定性定语从句中作宾语时，引导词可以省略，但引导非限定性定语从句的关联词不
能省。
如：He was eager to go to the hospital to see his stepmother, whom he loved and respected as his own mother.
他急于想去医院看望他的继母，他把他的继母当作亲生母亲一样热爱和尊敬。
The American journalist(whom/who) the announcer mentioned in the news broadcast is said to have been killed by the gangsters.
播音员在新闻广播中提到的那位美国记者据说已经被匪徒杀害了。
两例中的关系代词都在从句中作宾语。由于第二例是限定性定语从句，可以省略关系代词；
第一例中的引导词不能省略，因为它引导的是非限定性定语从句。
5、表示“正如”的含义时，通常用as引导非限定性定语从句，也可用which引导；但置于句
首时，只能用as引导。
如：China has basically succeeded in defeating SARS, which/as we have expected.
正如我们所预料的那样，中国已基本上战胜了“非典”。
As is well known to everybody, Tai wan is an inseparable part of China.
众所周知，台湾是中国不可分割的一部分。
但是当非限定性定语从句是否定含义时，就只能用which(而不用as)引导。
如：He didn't win the championship, which I hadn't expected.
他没获得冠军，这一点是我没预料到的。
?非限制性定语丛句中as, which的区别：
1、which引导非限制性定语丛句代表前面的整个句子的时候，一般是对主句的结果的说明。
如：He grows too fast, which makes him taller than his classmates.
2、as引导非限制性丛句代表前面整个句子时一般来讲丛句的谓语动词有三种：
A. 含有be动词：
如：He failed the exam, as is natural.
B. 实意动词的被动形式：
如：As is reported, the fire caused a great loss.
C.感官动词和意识类动词如：
如：see, hear, notice, know, learn, realize 等。
As you know, I am a teacher.
3、as可翻译为正如，它引导的丛句可位于主句之前，也可位于主句之后；which引导的该
丛句只能位于主句之后。
例1：__A___he realized, I was very useful to him.
例2：This elephant is like a snake, ___A__anybody can see.
例3：The sun gives us light and heat, __B___makes the plan tgrow well.
A. As(as)
B. which
C. that
D. who
?限定性定语从句与非限定性定语从句的区别：
?非限制性定语从句的关系词：
?非限定性定语从句的使用规则及注意事项：
1、which引导的非限定性定语从句是用来说明前面整个句子的情况或主句的某一部分。
2、在引导限定性定语从句时，that有时相当于in which, at which, for which或at which。
其中，介词的选用，依据从句中的动词所需搭配的介词来选用。例句：
①Attitudes towards day dreaming are changing in much the same way
that(inwhich)attitudes towards night dreaming have changed.
人们对白日做梦的态度正在改变，这与人们对夜间做梦的看法的变化有非常相似之处。
②I like the music for the very reason that(for which) he dislike it.
我出于某种原因喜欢这种音乐，而他恰恰与我相反。
③We arrived the day that(on which) they left.
刚好我们到的那天他们走了。
3、as有时也可用作关系代词。
4、在非限定性定语从句中，关系词不能用that
442051Tom won the game, ______ was really beyond his wildest dream..435726The
growing speed of a plant is influenced by a number of fa..194316They will fly to the Shanghai World Expo, _____they plan to ..435360Li Ning was able to set up a school for gymnasts in 1991, _..398437He helped me a lot with my English learning,was very kind of..208616My neighbors used to give a hand in time of trouble, was ver..
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
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)
非限定性定语从句起补充说明作用，缺少也不会影响全句的理解，在非限定性定语从句的前面往往有逗号隔开，如若定语从句有限制性和非限制性两种。限制性定语从句是先行词不可缺少的部分，去掉它主句意思往往不明确；非限制性定语从句是先行词的附加说明，去掉了也不会影响主句的意思，它与主句之间通常用逗号分开，将非限定性定语从句放在句子中间，其前后都需要用逗号隔开。 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。 ① which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 years 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，which is a clear liquid，has many uses. 水是一种清澈的液体，有许多用途。 The 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。 ② which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 careless，which we should not be. 她总是马虎大意，我们可不应该这样。
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：

限制性定语从句和非限制性定语从句的用法 限制性定语从句 形式上：不用逗号“，”与主句隔开。 意义上：是先行词不可缺少的定语，如删除，主句则失去意义或意思表达不完整。 译法上：译成先行词的定语：“．．．的” 关系词的使用上：A．作宾语时可省略B．可用that C．可用who 代替whom 非限制性定语从句 形式上：用逗号“，”与主句隔开。 意义上：只是对先行词的补充说明，如删除，主句仍能表达完整的意思。 译法上：通常译成主句的并列句。 关系词的使用上：A．不可省略B．不用that C．不可用who 代替whom 限制性定语从句举例： The teacher told me that Tom was the only person that I could depend on. 老师告诉我说汤姆是我唯一的可以依靠的人。 China is a country which has a long history. 中国是一个历史悠久的国家。 In the street I saw a man who was from Africa. 在街上我看到一个来自非洲的人。 非限制性定语从句举例： His mother, who loves him very much, is strict with him. 他妈妈十分地爱他，对他要求很严格。China, which was founded in 1949, is becoming more and more powerful. 中国是1949年成立的，现在正变得越来越强大。 Last summer I visited the People’s Great Hall, in which many important meetings are held every y ear. 去年夏天，我参观了人民大会堂，在那儿每年都要举行许多重要会议。
考点23 限制性定语从句与非 限制性定语从句 高考频度：★★★★★ 考向一非限制性定语从句 非限制性定语从句是对意义已经非常明确的先行词给予补充、说明，删去非限制性定语从句，主句的意思仍是概念清晰、结构完整的。非限制性定语从句的引导词有who，whom，which，whose，as，when，where等，that不可用于引导非限制性定语从句，从句之前要用逗号。 先行词指人，则用who，whose，which等； 先行词指物，要用which； 先行词表时间或者地点，并在句中作时间状语或者地点状语时要用when或者where引导。 一、使用非限制性定语从句的情况： 1. 关系代词指代整个主句时，使用非限制性定语从句。 ?You did a lot for me, for which I was grateful. 你为我做了许多，对此我很感激。 ?The Diaoyu Island belongs to China, as is known to us. 众所周知，钓鱼岛属于中国。 ?A middle-aged woman killed her husband, which frightened me very much. 一个中年女子杀害了自己的丈夫,这令我十分恐惧。 2. 当先行词指的是世界上独一无二的事物或人名地名等专有名词时，使用非限制性定语从句。 ?China, which is my motherland, is developing fast. 中国是我的祖国，正在快速发展。 ?Eason, who was a pop star, got married last year. 伊森去年结婚了，他是明星。 ?Last Sunday they reached Nanjing , where a conference was to be held. 他们上周日到达南京，有个会议要在那里举行。
非限制性定语从句用法 一．关系代词Who、Whom、Which、As、Whose Who指人，在从句中充当主语Whom在从句中充当宾语 1.Lintao, who is our monitor, was praised by our teacher.(主语) 2.Peter, whom you met in Paris, has arrived back from vacation. (宾语) Which 代指主句中的一个词或某一部分或整个句子 1.The apple trees, which I planted, hasn’t produced any fruit. （一个词、宾语） 2.I am taking some weight-loss pills, which are quite popular here. （一个词、主语） 3.He said that we had never seen her before, which was not true.（一个部 分） 4.Jone passed the exam, which made his parents very happy.（整个句子）Whose 代指定语（名词所有格或形容词性物主代词） 1.My cousin, whose body is slim, took part in the activities. 2.Daniel, whose brother I share a room with, has gone abroad. 二．关系副词when、where Where在从句中充当地点状语 1.The toy is in the drawer, where I often keep them. 2.The story happened in Hunan, where Chairman Mao was born. When在从句中充当时间状语 1.I left on Sunday, when everyone was at home. 2.We will set off next month, when he feels better.
限定性定语从句与非限定性定语从句的区别 一、在句中作用不同 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。 二、外在表现形式不同 限制性定语从句因与先行词关系密切,所以不可以用逗号将其与主句隔开;而非限制 性定语从句与先行词关系不十分密切,所以可用逗号将其与主句隔开。 例1. Do you remember the girl who taught us English? 你还记得教我们英语的那个女孩吗? 例2. Clock is a kind of instrument which can tell people time. 钟是一种能够告诉人们时间的仪器。 例3. This is the place where he used to live. 这就是他过去居住的地方。 例4. Mr. Zhang, who came to see me yesterday, is an old friend of mine. 张先生昨天来看我,他是我的一位朋友。 例5. We walked down the village street, where they were having market d ay. 我们沿着村里的大街向前走去,村民们正在那里赶集。 析:在前三个例句中,定语从句与先行词关系密切,为限制性定语从句,不可用逗号将其与主句隔开。在后两个例句中,定语从句与先行词关系不密切,为非限制性定语从句,可用逗 号将其与主句隔开。 三、先行词内容有所不同 大多数限制性和非限制性定语从句的先行词往往为某一个词或短语,而特殊情况下非限制性定语从句的先行词也可为整个主句,此时非限制性定语从句常由which 引导。
限制性定语从句和非限制性定语从句六大区别及练习 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) Mr. Smith, who is our boss, will leave for Japan next week. 我们的老板史密斯先生下周要去日本。(先行词为专有名词，要用非限制性定语从句修饰) Her father, who has a lot of money, wishes her to study abroad. 她父亲很有钱，希望她出国学习。(先行词为表独一无二意义的普通名词，要用非限制性定语从句修饰) 区别六：关系词不同 关系词that和why可用于限制性定语从句中，通常不用于非限制性定语从句；另外，在限制性定语从句中，关系词有时可以省略(参见本章有关内容)，而在非限制性定语从句中关系词一律不省略。 【巩固练习】 1. — Is that the small company you often refer to? — Right, just the one _______ you know my father used to work for years.

限制性定语从句与非限制性定语从句的区别 限制性定语从句提供有关主语或宾语的重要信息，起限定作用，与被修饰部分的关系紧密，如果省略该从句会使主句语义表达不完整。例如： This is the very pers on that is wan ted by the police He is the man who /that lives n ext door . It was a meeting whose importanee I did not realize at the time . 非限制性定语从句只是用来对被修饰部分作补充性的说明，与先行词关系比较松散，先行词与从句间可以用逗号隔开，从句可略去： He will not be able to spe nd the holiday with his family, which is a big annoyance to him. The minister , who is to visit our university , is said to be a Qin ghua Uni versity graduate. The book, which your sister bought you in Xinhua Bookstore , is very useful in impro ving your spoke n En glish. The bus in essma n, whose suitcase has bee n found by a stra nger , has left for Beiji ng. 如果定语从句的先行词是专有名词或是带有形容词性物主代词(my, his, etc)或形容词性指示代词(this, that, etc) 作限定词的名词词组，其后的 定语从句通常为非限制性的。例如： The Thames which is now clea n eno ugh to swim in , was polluted for over a hun dred years. My mother, who has been on a visit to Australia , will fly back tomorrow. All of these books, which have been donated by visiting professors , are to be used by the children in Hope School. 限制性定语从句的先行词只能是名词，代词或名词性词组，而非限制性定语从句的先行词除了是名词及名词性词组外，还可能是句子的一部分或是整个句子。例如： They say he plays truant, which he doesn 't. [which 指代plays trua nt] The meeti ng was put off till n ext mon th, as we hoped. [as 扌旨前
