1、读书之法 ,在循序而渐进 ,熟读而精思高中英语语法 -定语从句专项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。定语从句中的关系词有两个作用,一是形式上,引导定语从句。二是意义上,代
2、替先行词在从句中做某种成分。这是理解定语从句和其他从句的关键。一、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/t
3、hat 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 befo
4、re 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)二、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 occasio
5、ns 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
6、/ 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。尤其是当先行词为way 和 reason 时,引导定语从句的关系词通常都省略。如:This is the reason (why,for which)I did it. I couldn t agree with the way (that,in which)she talked to her p
7、arents. 三、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。Ill 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:精选学习资料 - - - - - - - - - 名师归纳总结 - - - - - - -第 1 页,共 10 页读书之法 ,在循序
8、而渐进 ,熟读而精思(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)Ill 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
9、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/关系副词。例 1. Is this museum _ you visited a few days age? A. whereB. thatC. on whichD. the one 例 2. Is this the museum _ the exhibition was held. A. whereB. thatC. on whichD. the one 例 1 变为肯定句:This museum is _ you visited a few days ago. 例 2 变为肯定句:T
10、his is the museum _ the exhibition was held. 在句 1中,所缺部分为宾语,而where, that, on which 都不能起到宾语的作用,只有the one既做了主句的表语,又可做从句的宾语,可以省略关系代词,所以应选D。而句 2 中 , 主、谓、宾俱全,从句部分为句子的状语表地点,既可用副词where,又因in the museum词组,可用介词in + which 引导地点状语。而此题中,介词on 用的不对,所以选A。关系词的选择依据在从句中所做的成分,先行词在从句中做主、定、宾语时, 选择关系代词 (who, whom, that, whi
11、ch, whose ) ;先行词在从句中做状语时,应选择关系副词 (where 地点状语, when 时间状语, why 原因状语)。四、限制性和非限制性定语从句1)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。 例如:This is the house which we bought last month. 这是我们上个月买的那幢房子。(限制性)The house, which we bought last month, is very nice. 这
12、幢房子很漂亮,是我们上个月买的。(非限制性)2)当先行词是专有名词或物主代词和指示代词所修饰时,其后的定语从句通常是非限制性的。例如:Charles Smith, who was my former teacher, retired last year. 查理 .史密斯去年退休了,他曾经是我的老师。My house, which I bought last year, has got a lovely garden.我去年买的的那幢房子带着个漂亮的花园。This novel, which I have read three times, is very touching. 这本小说很动人,我已
13、经读了三遍。3)非限制性定语从句还能将整个主句作为先行词, 对其进行修饰, 这时从句谓语动词要用第三人称单数。例如:He seems not to have grasped what I meant, which greatly upsets me.他似乎没抓住我的意思,这使我心烦。Liquid water changes to vapor, which is called evaporation. 液态水变为蒸汽,这就叫做蒸发。说明:关系代词that 和关系副词why 不能引导非限制性定语从句。五、介词 +关系词1)介词后面的关系词不能省略。2)that 前不能有介词。3)某些在从句中充当时
14、间,地点或原因状语的介词 +关系词 结构可以同关系副词when 和 where 互换。例如 This is the house in which I lived two years ago. 这是我两年前住过的房子。This is the house where I lived two years ago. Do you remember the day on which you joined our club? 还记得你加入我们俱乐部的那一天吗?Do you remember the day when you joined our club? 六、 as, which 非限定性定语从句由 a
15、s, which 引导的非限定性定语从句,as和 which 可代整个主句,相当于and this 或 and that。 As一般放在句首,which 在句中 。例如:精选学习资料 - - - - - - - - - 名师归纳总结 - - - - - - -第 2 页,共 10 页读书之法 ,在循序而渐进 ,熟读而精思As we know, smoking is harmful to ones health. 如我们所知,吸烟有害健康。The sun heats the earth, which is very important to us. 太阳使地球暖起来,这对我们人类很重要。典型例题
16、1)Alice received an invitation from her boss, _came as a surprise. A. itB. thatC. whichD. he 答案 C. 此为非限定性从句,不能用that 修饰,而用which.,it 和 he 都使后句成为句子,两个独立的句子不能单以逗号连接。况且选he 句意不通。2)The weather turned out to be very good, _ was more than we could expect. A. whatB. whichC. thatD. it 答案 B。which 可代替句子,用于非限定性定语
17、从句,而what 不可。 That 不能用于非限定性定语从句,it 不为连词,使由逗号连接的两个句子并在一起在英语语法上行不通。3)It rained hard yesterday, _ prevented me from going to the park. A. thatB. whichC. asD. it 答案 B. as 和 which 在引导非限制性定语从句时,这两个关系代词都指主句所表达的整个意思,且在定语从句中都可以作主语和宾语。但不同之处主要有两点:( 1) as 引导的定语从句可置于句首,而which 不可。( 2) as 代表前面的整个主句并在从句中作主语时,从句中的谓语必
18、须是系动词;若为行为动词,则从句中的关系代词只能用which.。在本题中, prevent 由于是行为动词,所以正确选项应为B。as 的用法例 1. the same as; suchas 中的 as 是一种固定结构, 和 一样 。例如:I have got into the same trouble as he (has). 我碰到了跟他一样的麻烦。例 2. as 可引导非限制性从句,常带有正如 。例如:As we know, smoking is harmful to ones health. 如我们所知,吸烟有害健康。As is known, smoking is harmful to
19、ones health. As 是关系代词。例1 中的 as 作 know 的宾语;例2 中,它充当从句的主语,谓语动词know 要用被动式。七、关系代词 that 的用法1)不用 that 的情况a) 引导非限定性定语从句时。例如:(错) The tree, that is four hundred years old, is very famous here. b) 介词后不能用。例如: We depend on the land from which we get our food. 我们依赖土地获得食物。We depend on the land that/which we get o
20、ur food from. 2) 只能用 that 作为定语从句的关系代词的情况a)当主句以 here,there 开头时。 Here is the hotel that youve been looking for. There is a seat in the corner that is still not taken. b )在不定代词,如:everything,anything, nothing, the one, all, much, few, any, little等作先行词时,只用that ,不用 which. All that is needed is a supply of
21、 oil. 所需的只是供油问题。 c )先行词有the only, the very修饰时,只用that 。 d )先行词为序数词、数词、形容词最高级时,只用that 。 It is the most important task that should be finished soon. 精选学习资料 - - - - - - - - - 名师归纳总结 - - - - - - -第 3 页,共 10 页读书之法 ,在循序而渐进 ,熟读而精思 e )先行词既有人,又有物时。 We were deeply impressed by the teachers and schools that we
22、had visited. f) 先行词本身是that 时,引导词须用which. 如: Whats that which flashed in the sky just now? g) 主句中有who,which 等疑问代词时,为避免重复只用that. Which is the T-shirt that fits me most? 八、分隔式定语从句(先行词与定语从句分离) 1、被介词短语分开。I have a painting by a painter which was sent to me for my birthday. 2、被谓语分开。The professor entered th
23、e hall who had just presented several lectuers. 九、 主谓一致问题。当关系词在从句中做主语时,须注意与从句谓语动词是否一致。从句谓语动词的形式1、取决于先行词。如:Mr Smith ,who is mow downstairs,is asking to see you. The Smith ,who are now downstairs ,are asking to see you. 2、两个特殊的结构。One of + 复数名词 +关系代词 +复数谓语。the (only,very,right,)one of +复数名词 +关系代词 +单数谓语
24、Jeff is one of the students who were awarded. Jeff is the only one of the students who was awarded. 十、有些“动词+介词”短语,不可把介词置于关系词前,否则,将会失去动词短语本身的含义。This is the town which the writer lived in 20 years ago.这个句子也可以改写成:This is the town in which the writer lived 20 years ago. 但是, This is the tape for which Im
25、 looking .这个句子是错的,因为look for 短语整体表达“寻找”的含义,分开来就没有这个含义了。所以,正确的表达应该是:This is the tape which Im looking for.除了 look for 短语之外,类似的短语还有:look after ,look forward to,care for,deal with,hear from/of/about, get through 等。十一、省略关系代词的情况。 1、关系代词在从句中做动词的宾语时。 I have been to the city twice (that/which)you just visit
