英语语法专题119:应用定语从句的注意事项 很重要(值得注意)
定语从句是从句中比较复杂的一类,既涉及先行词、关系代词、关系副词的用法,也涉及各种句法结构、时态、语态、语气等,因此应注意归纳并掌握。
一、关系代词和关系副词的省略
关系代词和关系副词在限制性定语从句的一些特定情况下皆有省略的情况。

我不喜欢你对我说话的那种方式。
例句:I appreciate the way (that)he dealt with this matter.
我很欣赏他处理这件事的方式。
二、宜用that不宜用which的情况
That和which在定语从句中都可作主语或宾语。作宾语时,均可省略。在通常情况下,可以互换使用。但有时that和which却不宜互换。
1)当先行词是不定代词all、little、few、much、something、anything、everything、nothing、none、some等时

4)当先行词既包括人又包括物时

客人高度赞扬了他们在少年宫看到的这些孩子和他们的表演。
例句:Can you remember the scientist and his theory thatwe learnt the other day ?

例句:Whois the person that came to see you yesterday ?
昨天来看你的那个人是谁?
例句:Whichis the dress that fits me most ?
哪件裙子最适合我啊?
三、宜用which不宜用that的情况
1)关系代词前有介词且指物或事时
例句:The middle school in whichI used to study has become a factory.
我过去学习的学校现在已经变成了一家工厂。
例句:The pen withwhich you are writing is Jeff"s.

一个无所畏惧的人敢说实话。
例句:The ones whoflatters me don"t please me.
那些奉承我的人并不能取悦我。
例句:We don"t want anyone whocan"t afford the tuition fee to drop out of school.

例句:There are many young men whosupports him.
有很多年轻人支持他。
五、as与which引导非限制性定语从句的区别
关系代词as与which引导非限制性定语从句可以用整个主句作为其先行词,指代上下文所说的某件事。但as和which具有不同的词义、句法和用法。
1)as引导的从句表示说话人的看法、态度、解释或评论
此时的as仍具有“正如,像,由......而知,与......一致”等某些连词的语义,有时可不必译出。常作实义动词(如see、know、hear、watch、remember、say、tell、show、expect、guess等)的宾语,这类动词与as几乎成了一种固定搭配。As引导的非限制性定语从句可以置于句首、句中或句尾。
例句:As is often the case,little boys tend to be very active and out of control.
小男孩总是活泼好动,难以控制,这是常见的情况。
例句:Einstein,as we know (=as is well known),is a famous scientist.
众所周知,爱因斯坦是一位著名的科学家。
例句:China is a beautiful country with long history,as is known to all.
众所周知,中国是一个有着悠久历史的美丽的国家。
2)which引导的从句对主句所叙述的事情进行补充说明,表明事物的状态或结果
Which此时指前面主句所提到的这件事,常译为“这一点,这件事”等。Which在句法上一般用作实义动词的主语或宾语,这时它所引导的从句与主句之间常含有并列、因果关系。主句与从句通常用逗号隔开,只能位于被修饰句子的后面。
例句:She stole her friend"s money,which(=and that) was disgraceful.
她偷了朋友的钱,这真是丢人的事。
例句:Tom was admitted to Harvard University,which(=and that) makes his parents very relieved.
汤姆被哈佛大学录取了,这件事让他的父母深感欣慰。
3)在从句中作定语或介词的宾语时,要用which
例句:He was educated at the local grammar school,after whichhe went on to Cambridge.
他在当地的文法学校上学,之后去了剑桥大学。
例句:Lily might possibly come,in whichcase I"ll ask her.
莉莉可能会来的,要是那样的话我就去问她。
4)不能省去非限制性定语从句中的be动词时,用which(反之则用as)
例句:Jane told me she had apologized to Lucy for her mistake,whichwas a lie.
简告诉我说她已经为她犯下的错误向露西道歉了,这是一个谎言。(was不可省略)
例句:As (was) planned,we met at the station after shopping.
按照计划,我们买完东西以后在车站见面。(可省略was)
5)当从句的谓语动词是否定形式或从句谓语动词带的是一个复合宾语结构时,一般用which而不宜用as
例句:He pretended not to know me,whichI didn"t understand.
他假装不认识我,这让我搞不明白。
例句:He seldom communicate with the classmates,whichI find quite strange.
他很少和同学交流,我觉得很奇怪。
六、the same...as与the same...that的用法区别
1)当先行词被the same修饰时,关系词既可以用as,也可以用that。在表示具体事物时,有时两者有一定的区别。一般来说,表示同一种类多用as,表示同一事物多用that。在抽象概念上,同种类和同一事物是没有绝对区别的,所以两个词可换用
例句:This is the samecomputer that I used yesterday.
这就是我昨天用过的那台电脑。
例句:This is the samecomputer as I used yesterday.
这台电脑跟我昨天用过的那台一样。
例句:I have the same opinion as/thatyou have.
我的观点和你的一样。
2)使用as时,它引导的定语从句中的动词可以省略,但使用that时,定语从句中的动词不可省略
例句:Women received the samepay as men (did).
妇女领导了和男子一样的工资。
=Women received the samepay that men received.
3)在“the same...that”结构中,that只是用来加强语气,强调“相同”。That可以省去而不改变句子的意思,甚至连名词前的same也可省去。但在“the same...as”结构中,same和as都不能省略
例句:This is the samesong (that) I heard the other day.
这就是我前几天听过的那首歌。
(=This is the song I heard the other day.)
4)在“the same...as”结构中的as可以充当关系副词,而that不可
例句:He lives in the samecity as I live.
他和我住在同一个城市。
(=He lives in the samecity that I live in.)
例句:Shall we meet at the sameplace as we last met ?
我们可以在上次相见的地方见面吗?
(=Shall we meet at the sameplace that we last met at ?)
七、“介词+关系代词”结构
“介词+which”可以替代when、where、why等;“介词+whom/whose”在定语从句中没有与之对应的关系代词可替代。
1)替代when
替代when在定语从句中作时间状语。
例句:I"ll never forget the days on which(when) we lived together.
我永远不会忘不了我们一起生活的日子。
例句:The year in which(when) the Tangshan earthquake happened was 1976.
唐山地震发生在1976年。
2)替代where
替代where,在定语从句中作地点状语。
例句:This is the town in which(where) Shakespeare was born.
这就是莎士比亚出生的城镇。
例句:The house in which(where) I lived ten years ago has been pulled down.
我十年前住的房子已经被推到了。
3)替代why
替代why,在定语从句中作原因状语
例句:There is no reason for which(why) we don"t attend the party.
我们没有理由不参加聚会。
例句:I"d like you to explain the reason for which(why) you were late again.
我想让你解释一下你又迟到的原因。
4)替代that
替代that,在定语从句中作方式状语、时间状语
例句:There are varieties of ways in which(that) we can solve this problem.
我们有很多方法可以解决这个问题。
例句:March is the best time in which/during which(that) farmers plough their fields.
三月是农民耕地的最佳时间。
5)“名词/代词+介词+关系代词”结构
此类结构常见的有some/several/a few/a little/many/more/most/the largest+of+which/whom等形式。
例句:Here are the questions,most of which(=of which some) I thought easy for you.
就是这些问题,我认为大部分对你来说很容易。
例句:Present at the meeting were almost experts on psychology,most of whom(=of whom most) came from the US.
出席会议的几乎都是心理学专家,其中大部分来自美国。
6)关系代词前介词的确定
①依据定语从句中动词或形容词某种习惯搭配来确定
例句:I bought a great many books,on whichI spent all my money that I saved.
我买了很多书,花了我所有的积蓄。
(on就是依据spend...on...结构来确定的)
例句:Trading leather shoes is the business to whichthe Greens are devoted.
皮鞋生意是格林家全力经营的事业。
(介词to是依据be devoted to结构而定的)
②依据与先行词搭配的具体意义而定
例句:In ten years,Jill went from working in the mailroom to running the company,in whichmore than 1000 people now work.
在十年的时间里,吉尔从在邮局上班做起,一直做到开公司,现在有1000多人在她的公司上班。
例句:I"ll never forget the time during whichI spent my childhood in the country.
我永远不会忘记我在乡村度过的童年时光。
③根据所表达的意思确定
例句:The colorless gas without whichthe plant cannot live is called carbon dioxide.
这种无色的、离了它植物就不能活的气体就是二氧化碳。
例句:You"ve anyway made several grammar mistakes,except for which your composition would be the best.
你不知为何犯了几个语法错误,要不是这些错误,你的作文将会是最好的。
④在英语中有时为了强调某一名词,不定式前也可加上关系词。
例句:Here is the money with whichto buy a computer.
这就是买电脑的钱。
(=Here is the money to buy a computer with.)
例句:Nancy is the right person on whomto depend.
南希是值得信赖的人。
(=Nancy is the right person to depend on.)
有些“动词+介词”习语如look for、look after、call on等不可把介词置于关系代词前。如果介词提前,将会失去动词短语的意义。
例句:My younger brother,afterwhom I have to look,is demanding.(×)
My younger brother,whom I have to look after,is demanding.(√)
我得照看我弟弟,真是让人费心。
八、特殊结构的定语从句
定语从句在实际运用的过程中,具有较强的灵活性,因此其结构也较为复杂,现将常见的特殊定语从句列举如下:
1)分隔式定语从句
定语从句一般紧接被它所修饰的先行词;但有时候它和先行词之间有可能插入其他成分,使它与先行词分隔开来,这种定语从句叫分隔式定语从句。这阅读文章时会经常遇到这种情况,因此要注意识别先行词。
一般说来,定语从句被分隔开来大致有以下三种情况:
①在先行词与定语从句之间插入一个状语
例句:There are many thousands of stars in the skythat are like the sun.
在太空中有成千上万颗像太阳一样的星星。
(that引导的定语从句在名词sky的后面,但不能修饰sky而应修饰先行词stars)
②在先行词与定语从句之间插入一个定语
例句:Do you remember one afternoon ten years agowhen I came to your house and borrowed a diamond necklace ?
你还记得十年前的一天下午我来到你家,找你借了一条钻项链吗?
(定语从句修饰afternoon而不是修饰years)
③先行词与定语从句被谓语分隔开来
此时,先行词通常是句子的主语,因定语从句较长,主句谓语较短,为使句子平衡,常将定语从句移至谓语之后。
例句:A new technician will cometomorrow who will teach you how to use the new equipment.
明天,教你们使用新设备的新的技术员会来。
2)混杂式定语从句
有时定语从句的关系词与从句中的句子成分之间会插入“人称代词+think/believe/guess等”表示某种态度的句子,这种定语从句被称为混杂式定语从句。
例句:That evening some Chongqing people saw something that they thoughtwas a UFO flying across the sky.
那天傍晚,一些重庆人看到了他们认为是不明飞行物的东西从天空中飞过。
例句:Many college students have mastered computer,driving and foreign languages,which we all knoware the most important things in today"s society.
很多大学生都掌握了计算机、驾驶和外语,我们都知道这些能力在当今社会是非常重要的。
3)多重定语从句
两个或两个以上的定语从句同时修饰一个先行词时,这样的定语从句叫作多重定语从句。
例句:Tibet is a place wherethe Tibetan people have been living for generations and which/that all the people across the world are dreaming of visiting.
西藏是西藏人民世代生活的地方,也是世界人民都渴望去观光旅游的地方。
例句:He said he would never forget the moment whenhe first met Gorky and which he regarded as the happiest in all his life.
他说他永远忘不了第一次与高尔基相间的时候,那一刻被他视作人生中最幸福的时刻。
多重定语从句中第二个以及之后的所有关系词都不能省略,以免引起句意的模糊不清。
例句:China is an attractive country whichhas the largest population,where there are lots of mysterious stories and legends and that many westerners are still not familiar with.
中国是一个充满魅力的国家,她拥有世界上最多的人口,有许多神秘的故事和传说,但也是很多西方人还不熟悉的过度。
4)省略式定语从句
在含有将来意义的定语从句中,可以省略主语和谓语的一部分(主要是情态动词和助动词),而代之以“介词+关系代词+不定式”的形式,这叫省略式定语从句,或叫作定语从句的缩略形式。主句的主语必须与不定式的逻辑主语一致,否则不能改成省略式定语从句。
例句:I intend to make friends with some English from whom to improveEnglish.
我打算交一些英国朋友,从他们那里我可以提高英语水平。
(完整句式是:I intend to make friends with some English from whom I can improve my English.)
例句:She dreams of earning a big sum from the stock market with which to buyher family a big flat.
她很想从股市赚一大笔钱给她的家人买一套大公寓。
(完整句式是:She dreams of earning a big sum from the stock market with which she can buy her family a big flat.)
九、定语从句与同位语从句的区别
1)被修饰词不同
同位语从句的先行词常是一些具体信息内容或一定内涵的名词,如idea、fact、news、hope、belief、suggestion、proposal、word、thought、doubt、truth、possibility、promise、order等,而定语从句的先行词可以是名词、代词、主句的一部分或是整个句子。
例句:The ideathat computers can recognize human voices surprises many people.
计算机能够识别人声的想法使许多人感到惊奇。(同位语从句)
例句:We are not looking into the questionwhether he is worth trusting.
我们正在调查的问题不是他是否值得信赖的问题。(同位语从句)
例句:The doctorwhom you are looking for is in the room.
你找的那位医生在房间里。(定语从句)
例句:His mother did allshe could to help him overcome the difficulty.
他妈妈尽最大努力帮他渡过难关。(定语从句)
2)从句表达的含义不用
定语从句是从句对其先行词的修饰或限制,属于形容词性从句的范畴而同位语从句是对前面抽象名词的进一步的说明和解释,属于名词性从句的范畴。
例句对比:The news thatour team has won the game was true.
我们队赢了那场比赛的消息是真的。(同位语从句,补充说明news到底是一个什么消息)
The news that he told me yesterday was true.
昨天他告诉我的那个消息是真的。(定语从句,news在从句中作told的宾语)
例句对比:I made a promise thatif anyone invested in my company I would make him very rich.
我许诺如果谁投资我的公司,我就会让他变成富翁。(同位语从句,补充说明promise到底是什么诺言)
The mother made a promise that pleased all her children.
妈妈许下一个令所有孩子都兴奋的诺言。(定语从句,promise在从句中作pleased的主语)
3)引导词及其在句子中的成分不同
一些引导词如how、whether、what可以引导同位语从句,但不能引导定语从句。
例句:The question whetherwe need new staff has not been considered.
我们是否需要新员工这个问题还没被考虑。(同位语从句)
例句:I have no idea whathas happened to him.
我不知道他发生了什么事。(同位语从句)
4)that引导的同位语从句与定语从句的区别
引导词that引导定语从句时,在从句中作主语或宾语(指物时还可以用which代替),并且作宾语时常常省略。That在同位语从句中仅起连接作用,不充当任何成分,并且不能省略,也不能用which代替。
例句:The order that we should send a few people to help the other groupswas received yesterday.
派几个人去帮助别的小组的命令是昨天收到的。
(同位语从句,是对order的具体解释,that虽不作成分,但不能省略)
例句:The order that we received yesterdaywas that we should send a few people to help the other groups.
我们昨天接到命令是,我们应该派几个人去帮助别的小组。
(定语从句,是名词order的修饰语,that在从句中作received的宾语,可以省略)
十、定语从句与定语从句和状语从句之间的转化
在转化的过程中,限制性的定语从句仍需要转化成限制性的,非限制性的定语从句仍需要转化成非限制性的。定语从句与分词的转化分为以下几种情况:
1)直接转化为-ing或-ed形式
这种形式只需去掉定语从句中的who/which is/was/are/were既可。
例句:The teacher (who is) giving a lecturenow just returned from England.
正在做演讲的老师刚刚从英国回来。
例句:I love the poems (which were) writtenby Shelley.
我喜欢雪莱的诗。
2)将动词的形式重新进行-ing形式的转化
例句:Look at the house.That is my home which stands at the top of the mountain.
→Look at the house,That is my home standingat the top of the mountain.
瞧那个房子,那就是我坐落在山顶上的家。
例句:My brother,who livedin France for ages,now lives in Beijing.
→My brother,having livedin France for ages,now lives in Beijing.
我哥哥在法国住过很多年,现在住在北京。
3)可转化为分词式的定语或状语
例句:My mother,who hasn"t been used toliving in the city,has made up her mind to settle in the country.
→My mother,not having been used toliving in the city,has made up her mind to settle in the country.
→Not having been used toliving in the city,my mother has made up her mind to settle in the country.
我妈妈由于不习惯住在城市,决定到乡村定居。
例句:Charles,who wasa brave man,returned to France.
→Beinga brave man,Charles returned to France.
勇敢的查尔斯回到了法国。
例句:Jenny,who had foldedthe letter,put it carefully in her pocket.
→Jenny,having foldedthe letter,put it carefully in her pocket.
→Having folded the letter,Jenny put it carefully in her pocket.
珍妮叠好信,小心翼翼地放进了衣兜里。
十一、定语从句的主谓一致
数名词+关系代词+谓语动词单数形式。
例句:I am not onewho is afraid of difficulty.
我是个不怕困难的人。
例句:Please choose me,who amqualified for this job.
请选择我,我适合做这项工作。
例句:That is one of the most valuable dictionariesthat have appeared in recent years.
那本词典是近几年来所见到的最有价值的词典之一。
例句:He is the only one of those workers who is able to do this job.
他是那些工人中唯一能做这项工作的人。
十二、定语从句的时态
定语从句的时态一般不受主句影响,主要根据具体的语境和意义而定。
例句对比:The professor who lecturedyesterday is from Peking University.
昨天做演讲的教授来自北京大学。(从句运用一般过去时)
The professor who is lecturingnow is from Peking University.
现在正在演讲的教授来自北京大学。(从句运用现在进行时)
The professor who will lecturetomorrow is from Peking University.
明天要来做演讲的教授来自北京大学。(从句运用一般将来时)
