主语从句
一定义：在复合句中充当主语成分的句子叫做主语从句。
二主语充当主语的句子类型：
1.常规主语从句，即句子在复合句中充当一个主语；主语从句的时态不受主句的时态影响和限制。
（1）That he finished writing the composition in such a short time surprised us all.
（2）Whether we will go for an outing tomorrow remains unknown.
（3）Who will be our monitor hasn't been decided yet.
（4）Whom we must study for is a question of great importance.
（5）What caused the accident remains unknown.
（6）Whatever you did is right.
（7）Who the watch belongs to is unknown.
（8）What we need is time.
（9）What we need are good doctors.
小结:
（1）引导主语从句连词有that,whether,who,what,whatever等；
（2）连词位于句首不能省略；
（3）主语从句大多数情况下视为第三人称单数，但也有例外，如例（9）
注意：当what引导的名词性分句作主语时，主谓一致问题极为复杂。
2. 为了防止句子头重脚轻，通常把形式主语it放在句首位置，真正主语搁置于句末
（1）It is certain that he will win the match.
（2）It is true that he has made a very important discovery in chemistry.
（3）It is very likely that they will hold a meeting.
（4）It is strange that he should do that.
（5）It is important that we all should attend the meeting.
（6）It is strange that the man should have stuck to his silly ideas.
（7）It is a pity that we won't be able to go to the south to spend our summer vacation.
（8）It is still a mystery what caused the accident.
（9）It is said that he has gone to shanghai.(=He is said to have gone to shanghai) （10）It is known to all that the gun powder was first invented by the Chinese.
（11）It is suggested that the work should be done with great care.
（12）It happened that the two cheats were there. (=The two cheats happened to be there)
小结:
（1）为避免头重脚轻，常以形式主语it引导从句。It+形式主语谓语+从句。
（2）由于主语从句一般被认为是单数形式，形式主语的谓语动词、be动词+表语均为单数第三人称形式或过去式.
主语从句的用法
主语从句与宾语从句两者的用法和在句中的作用是不同的，下面从它们的各自用法来介绍。
一．主语从句
主语从句定义：在句子中担当主语的是一个从句，这个从句就叫做主语从句。主语从句是在复合句中充当主语的从句，通常放在主句谓语动词之前或由形式主语it代替，而本身放
在句子末尾。
1. It 作形式主语和it引导强调句的比较
①主语从句常用it作形式主语，一般常用句型为：It is+{名词/形容词/过去分词}+主语从句例如：
It is still a question whether she will come or not.
It is strange that you should like him.
It is still unknown which team will win the match.
另外，还有一些比较多见的结构：
It turned out that……;
It has been proved that……;
It happened/occurred that……;
It is well-known that……等等
②而强调句则不同，它的结构是：It+be+被强调部分+that+从句
强调主语：It is the times that produce their heroes.时势造英雄
强调宾语：It is English that Prof.Lin teaches us.
强调状语：It was in shanghai that I saw the film.
判断是否是强调句有一个方法，就是将that以后的“句子的其余部分”拿出来单独看，看有没有缺成分，缺的是什么成分，再把谓语动词后面that前面的那部分，带到你认为缺成分的地方，如果放进去是一句完整的句子了，那就说明是强调句。
2. 用it 作形式主语的结构
(1) It is +名词+that从句
It is a fact that …事实是……
It is an honor that …非常荣幸
It is common knowledge that …是常识
(2) it is +形容词+that从句
It is natural that…很自然……
It is strange that…奇怪的是……
(3) it +不及物动词+that从句
It seems that…似乎……
It happened that…碰巧……
(4) it is+过去分词+that从句
It is reported that…据报道……
It has been proved that…已证实……
3.主语从句不可位于句首的五种情况
(1) if 引导的主语从句不可居于复合句句首。
(2) It is said , (reported) …结构中的主语从句不可提前。例如：
It is said that President Jingo will visit our school next week.
(3) It happens…, It occurs…结构中的主语从句不可提前。例如：
It occurred to him that he failed in the examination.
(4) It doesn’t matter how/whether …结构中的主语从句不可提前。例如：
It doesn’t matter whether he is wrong or not.
(5) 含主语从句的复合句是疑问句时，主语从句不可提前。例如：
Is it likely that it will rain in the evening?
4. What 与that 在引导主语从句时的区别
What 引导主语从句时在从句中充当句子成分，如主语．宾语．表语，而that 则不然。
例如：
What you said yesterday is right.
二．宾语从句用以区分主语从句的几个特征：
1、引导词：what\which\whose\when\whether\if\where
2、语序：宾语从句必须是用陈述语句。（名词性从句都是陈述语序）
如：I think that you must work harder.
宾语从句的引导词、连接词的区别、否定转移等现象。
补充：从句的语序永远是陈述句。

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 years ago，have not borne any fruit.

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：As is known to the United States, Mark Twain is a great American writer.
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）

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。

关系词
①引导非限定性定语从句的关系代词:as,which.
②引导非限定性定语从句的关系副词主要有：when,where。
注意：不能用that作为关系代词的两种情况：①非限定性定语从句；②介词+关系代词区别
1、as引导的定语从句可以放在句首、句中和句尾，which引导的定语从句可置于句中或句尾。
2、当as后面有“is或was+过去分词”构成的被动语态时，be动词is或was可省略。
3、as有时也可用作关系代词。若as在从句中作主语，其引导的句子可以放在句首或句中。但which引导的非限制性定语从句只能放句中。
4、as有正如…一样、按照、正像、因为的意思，所以常用于肯定句，而which则用于肯定，否定都可以。
5、在固定结构中使用as 例如：the same … as 、as … as。
例句：
1 Dorothy was always speaking highly of her role in the play, which , of course, made the others unhappy.（从句部分的意思为：这当然使别人不高兴；而不能译为正如使别人不高兴。故用which。）
2 Chongqing is not the same city as we have seen in other places.
重庆和我们在其它地方看过的城市不一样。
常见易错题目及解答方法
1. 引导限制性定语从句时，关系代词which可以与that互换；但引导非限制性定语从句时，只能用which。
例1.She heard a terrible noise, ______ frightened her.
A. that
B. which
C. what
D. who
例2.She heard a terrible noise ______ frightened her.
A. that
B. /
C. what
D. who
解析：例1意为：“她听到一个可怕的声音，这使她感到恐惧。”that不能用于引导非限制性定语从句，故选B。例2意为：“她听到了一个使她恐惧的可怕声音。”引导修饰noise 的限制性定语从句可以用which或that来引导,故选A。
2. 先行词为reason时，限制性定语可以用why或for which来引导；非限制性定语从句则只能用for which来引导。
例3.I had told them the reason, ______ I didn’t attend the meeting.
A. for which
B. at which
C. for whom
D. why
例4I had told them the reason ______ I didn’t attend the meeting.
A. when
B. which
C. why
D. for that
解析：例3意为：“我早已把理由告诉他们，于是我没有出席会议。”先行词为reason 时，非限制性定语从句应用for which引导，故选A。例4意为：“我已经把为什么没有出席会议的原因告诉他们。”the reason why...是常见搭配，答案为C。
3. 引导限制性定语从句的关系代词在从句中担任宾语时可以被省略；但引导非限制性定语从句的关系代词即使作宾语也不能省略。
例5.He was eager to go to the hospital to see his stepmother,______ he loved and respected as his own mother.
A. as
B. which
C. /
D. whom
解析：本句意为：“他急于去医院看望他的继母，他像对待亲生母亲一样孝敬她。”关系代词whom引导非限制性定语从句并作宾语，不能被省略，故选D。
4．引导限制性定语从句时并作从句宾语的关系代词whom可以用who来代替；但在非限制性定语从句中，whom就不能用who替换。
例6.Do you know Tom, _____ we talked about?
A. which
B. that
C. whom
D. who
例7.The American journalist ______ the announcer mentioned in the news broadcast is said to have been killed by the gangsters. Which of the following is wrong?
A. who
B. whom
C. whose
D. /
解析：例6意为：“你认识汤姆吗? 我们谈到过他。”应选C。例7意为：“播音员在新闻广播中提到的那位美国记者据说已遭歹徒杀害。下列哪一项是错误的？”关系代词作mentioned的宾语且指人时，可用who/whom/that，在限制性定语从句中可省略，故C是错的。
5．当非限制性定语从句修饰整个主句时，其关系代词只能用as ，不能用which。此时非限制性定语从句可置于主句之前、之后或之中。
例8______ I expected, he didn’t believe me.
A. Which
B. As
C. That
D. When
解析：本句意为：“正如我所预料的那样，他不相信我的话。”非限制性定语从句修饰整个主句，应用as引导，故答案为B。
例9.Mary was late for school,______ often happened.
A. as
B. for which
C. that
D. why
解析：本句意为：“玛丽上学迟到了，这是常有的事。”根据句意，关系代词as引导的非限制性定语从句修饰前面的主句，其位置非常灵活，故答案为A。
6. 由“介词+关系代词”引导非限制性定语从句，关系代词指代整个主句时，不能用as，只能用which。
例10.He bought the car for more than $20,000,______ his father was angry.
A. about that
B. with as
C. when
D. with which
解析：本句意为：“他花两万多美元买了这辆车，他父亲对此很生气。”which位于介词with的后面，指代前面的主句，故答案为D。
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. as有时也可用作关系代词。as引导非限制性定语从句，若as在从句中作主语，其引导的句子可以放在句首，也可以放在句中。但which引导的非限制性定语从句只能放句中。
例句：
As is reported in the newspaper ，some artistic treasures(艺术珍品）will be on show at the exhibition （展览品）on the weekend.
3. 在非限定性定语从句中，关系词不能用that和those。

6.限定性定语从句:不能修饰一个事件。
非限定性定语从句:可以修饰一个事件。
功能用途
限定性定语从句与主句的关系很紧凑，对其先行词起限定、修饰的作用。如果将其去掉，会影响句子意思的完整性；有时甚至于引起费解、误解。例如：
1.Rain forests are being cleared for valuable timber and other resources to speed up the economic growth of the nations in which they are located .
为了加速他们各自所在国家的经济发展，热带雨林作为有价值的原木和其他资源正为人们所砍伐。
2.Ocean currents affect the climates of the lands near which they flow.
洋流影响其流经的附近地区的气候。
3.They explained the reason to us why they had hated us before.
他们向我们解释为什么他们不喜欢我们的原因。
非限定性定语从句在形式上就与主句很松散，它与主句之间有一个逗点"，"隔开；它对其先行词没有限定、修饰的作用，只起补充、说明的作用。有时也用它来对全句或句中某个成分进行补充、说明。即使将其去掉，也不会影响句子意思。由于上述原因，非限定性定语从句在表达意思方面也有别于限定性定语从句。另外，非限定性定语从句在中文译文里，我们往往将其作为一个分句处理，而不把它作定语翻译。例如：
Earlier , the Babylonians had attempted to map the world , but they presented it in the form of a flattened disc rather than a sphere , which was the form adopted by Ptolemy .
更早之前，巴比伦人曾试图绘制世界地图，但是他们把它绘制成平盘状而不是托勒密所采用的球体状。
（此句中，非限定性定语从句是对先行词a sphere进行补充、说明。）
The combination of satellites, which transmit information , computers , which store information , and television , which displays information , will change every home into an
education and entertainment center .
卫星能传输信息，计算机能储存信息，电视能显示信息，把这些手段结合起来可以使每个家庭都成为教育娱乐的中心。
（此句中，三个非限定性定语从句分别对三个先行词：satellites ，computers和television进行补充、说明。如果去掉这三个非限定性定语从句，那么句子可简化为：The combination of satellites , computers and television will change every home into an education and entertainment center .）
The sun heats the earth , which makes it possible for plants to grow .
太阳给予大地热，这就使植物的生长成为可能。
（此句中，非限定性定语从句是对全句进行补充、说明，将全句表达的意思看成"一件事情）。
The old man has a son , who is in the army .
那位老人有一个儿子，他在部队工作。
（此句中，非限定性定语从句是对先行词son进行补充、说明。但本句所传达的信息是："这位老人只有一个儿子" 。如果将此句改写成限定性定语从句："The old man has a son who is in the army . "那位老人有一个在部队工作的儿子。那么，限定性定语从句就要对先行词son进行限定、修饰。这样一来，句子所传达的信息就变成了："这位老人有一个儿子在部队工作"，也就是说可能老人还有其他的儿子在干别的工作）
非限制性定语从句 一、与限制性定语从句的区别： 限制性定语从句是不能去掉的，否则剩下的部分就失去意义而不能成立。非限制性定语从句则不然，它只对所修饰的词作进一步的说明，去掉之后并不影响整个句子的含义。在形式上，非限制性定语从句与主句之间通常必须有逗号隔开。试比较： ①A man who doesn’t want to learn from others can’t achieve much. ②I come from China, which has a long history of 3000 years. 二、as和which的区别 翻译下列句子，然后找出每句的先行词。 1. A five-year-old boy can speak two foreign languages, which surprises me. 2.The weather turned out to be very good, which was more than we could expect. 3.Tom is tall, as are his brothers. 4.As we all know, paper was first made in China. 归纳：as和which在非限制性定语从句中可代替整个主句。 as可用在固定搭配中 as anybody can see正如人人都能看到的那样 as has been said before如前所说 as often happens 正如经常发生的那样 as has been pointed out 正如已指出的 as we all known/ as is well known to us众所周知 as mentioned above如上所述 1.___________ often happens, he is late again. 2.He came here very late, ____________ was unexpected. 3.He has passed the text, ___________ nobody knows. 4.Tom has made rapid progress, ____________ makes me very happy. 5.Mother was terrified, ____________ I could see from her eyes. 6.Our team lost the game, ____________ was reported in the newspaper. 巩固练习： 一、完成句子。 1.射击最初只是生存工具，19世纪末才发展成为一项体育运动。 Shooting, _________was a means of survival originally, developed into a sport only in the late 19th century. 2.中国吸烟人数：约 3.5亿；分布：男性75％;女性：25％ Currently China has about 350 million smokers, among _________75% are men and 25% are women. 3.受二手烟影响人数：约5.4亿；因二手烟死亡人数：超过10万/年 Around 540 million people are affected by second-hand smoke, ________causes 100,000 deaths per year. 4.众所周知，2008年北京将举办奥运会。英语作为一种国际语言，将会在交流 中起着重要作用。作为一名高三学生，我们应抓住现在的学习机会努力学好它。只有这样，才能为奥运贡献自己的力量。 _________ is known to all, Beijing will host the 2008 Olympic Games. English, __________ is an international（国际的）language, plays an important part in communicating（沟通、交流）with foreigners. We Senior Three students should catch this opportunity（机会）to learn it well, by __________ we can make our contribution （贡献）to the Olympic Games. 二、英译汉。 1.Don’t cheat me. I’m no longer the boy that I was three years ago. ______________________________________________________________________ 2.There is no difficulty that cannot be overcome. ______________________________________________________________________
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
志伟教育限制性定语与非限制性定语练习题 一、复习关系词的用法：（在对应用法处打钩） 1.The person _______ is standing there is my teacher. 2.The person ________ you spoke just now is my teacher. 3.The person ________ you spoke to just now is my teacher. 4.I bought a car__________ cost little. 5.The car __________ I bought yesterday cost little. 6.This school is the one _________ I studied ten years ago. 7.This is the little girl ___________ parents were killed in the earthquake. 8.The boss in ________ company my father worked is a very kind man. 9.I will remember that day __________ I first came to Beijing. 10.There are several reasons _________ we can’t do that. 1.who/that 2.to whom 3.who/whom/that 4. which/that 5. which/that 6. in which/where 7.whose 8.whose 9. when/on which 10.why/for which 二、观察下列句子并翻译 1.I’m taking weight-loss pills called Fat-Less, which are quite popular among young women here. ____________________________________________________________________ 2.My mother, who you met last year, keeps telling me not to take them because they are dangerous. _____________________________________________________________________ 3. 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。
二轮复习书面表达写作技巧之三：如何写好定语从句 定语从句的正确使用能够比较明显地反映出考生对于语言具有较高的掌握能力，所以建议考生一定要在写作中至少使用一个恰到好处的定语从句。 (一)定语从句的类型 1．关系代词引导的定语从句 关系代词who, whom, whose, that, which, as引导的定语从句是写作的一大重点，尤其是which和as引导的非限制性定语从句在高考范文中更是屡见不鲜。 ①(2018?北京高考书面表达)Last week, we took the foreign students to experience the authentic tea culture, which turned out to be extremely rewarding.上周，我们带领外国学生体验了正宗的茶文化，结果证明非常值得。 ②(2017?全国卷Ⅲ书面表达)Secondly, you will make some good friends who are also interested in playing table tennis.第二，你会交到一些好朋友，他们也很喜欢打乒乓球。 ③As you see, the Chinese people are hard-working. 你知道，中国人民是勤劳的。 2．关系副词引导的定语从句 关系副词引导的定语从句是指when, where, why引导的定语从句。
①(2018?北京高考书面表达)Its Chinese Literature major is perfect for you where you can be completely soaked in Chinese profound history and rich culture. 它的中国文学专业对你来说是适合的，在那儿你可以完全沉浸在中国深厚的历史和丰富的文化中。 ②(2014?安徽高考书面表达)I think the reason why you are always angry may be the high pressure of study. 我认为你总是发脾气的原因可能是学习上的巨大压力。 3．“介词＋which/whom”引导的定语从句 (2017?北京高考书面表达)Material collecting took us a whole week, during which we interviewed our teachers and took pictures of every aspect of school life. 搜集材料花了我们整整一周的时间，在此期间我们采访了老师并拍摄了学校生活的各个方面。 (二)定语从句的写法 定语从句是比较难掌握而又是考生在写作中喜欢尝试的复杂句，在写作时可采用“三步法”： [示例] 第一步：写出两个简单句。 ①The foreigner is from Canada. ②He visited our class yesterday.
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。

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 一．限定性定语从句与非限定性定语从句的区别 二．引导非限制性定语从句的关系代词有as，which，who， whom，whose等，作定语从句的主语、宾语、表语及定语。关系副词有when，where等，作定语从句的状语。关系代词和关系副词在定语从句中一般不能省。 1.who，whom，whose等引导非限制性定语从句时，指代人的普通名词、专有名词等。表示正是或专指先行词等情况。在定语从句中作主语、宾语、定语等。Bob's father，who worked on the project，spent four years in Egypt． 鲍勃的父亲从事这项工程，在埃及度过了四年。 His mother，whom he loved dearly， died in 1818． 他非常爱戴他的母亲，她死于 1818年。 Mr King，whose legs were badly hurt， was quickly taken to hospital． 金先生的腿受了重伤，他很快就被送去住院了。 2.when，where引导非限制性定语从句时，作定语从句的状语。when=and then， where =and there。why不引导非限制性定语从句。 He was quickly taken to hospital，where a doctor wanted to examine Mr King's legs．金先生很快被送去住院，在那里一个医生要检查他的腿。 We will put off the outing until next week，when we won't be so busy．我们把郊游推迟到下个星期，当我们不忙的时候。
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。
定语从句和名词从句的区别在于，名词从句的连接词可以从当成分，
状语从句 地点状语从句 方式状语从句 原因状语从句 目的状语从句 结果状语从句 条件状语从句 让步状语从句 简单句：只能有一个动词，就是一个谓语。主语可以有多个，可以由连词连接主语。 组合句：有连词连接的两个句子，连词有for, and, nor, but, or, yet, so.或是用分号，再加上一个连接词，连接词有：however, as a result ,in in fact ,therefor, thus, instead, also, in addition 复杂句:就是一个简单句，加上一个或多个的从属分句或是关系从句 Because he is kind, and treats people friendly, people in her company love him.
People in her company love him because he is kind .because 放句首的时候，需要逗号。 组合复杂句：就是多个简单句，加上多个从属分句，再加上关系从句 After连接的是复杂句the students had reviewed his notes, he thought he was ready for the test,这部分是插入的关系从句and he was right.其实就是几个复杂 句连在一起。 写作常犯错误：拼写错误，漏写，大写，时态，主谓一致，标点符号，单复数，不必要的单词，形容词用错，单词顺序，简单句太多，THERE BE 句型太多，I 开头的句型太多。从句太少。平行结构，增减冠词，少介词，没有指明上文的人和物，不给具体的例子。说话没有逻辑性。没有连词。
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.
