英语定语从句语法解析 篇一

Please tell me everything you know about the matter.
Thats all we can do at the moment.
2.as引出的限制性定语从句

Such people as were recommended by him were reliable.
Ive never seen such a talented young man as he is.
I have the same trouble as you 。
3.as引出的非限制性定语从句

I live a long way from work, as you know.
She did not, as her friend had feared, break down.
As is generally accepted, economic growth is determined by the smooth development of production.
4.分隔式定语从句

定语从句归纳及用法 篇二
I 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，英语定语从句知识和用法概述。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）
II. 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"介词+ 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。
III.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/关系副词。
例1. Is this museum ___ you visited a few days age?
A. where B. that C. on which D. the one
例2. Is this the museum ____ the exhibition was held.
A. where B. that C. on which D. the one
答案：例1 D，例2 A
例1变为肯定句： This museum is ___ you visited a few days ago.
例2变为肯定句： This 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，英语语法《英语定语从句知识和用法概述》。
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, which, 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） 。
IV. 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。
V. 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 www.cha www.1126888.com yi5.com中充当时间，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?
VI. as, which 非限定性定语从句
由as, 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：
As we know, smoking is harmful to one's 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
1）Alice received an invitation from her boss, ___came as a surprise.
A. it B. that C. which D. 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. what B. which C. that D. it
答案B。which可代替句子，用于非限定性定语从句，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. that B. which C. as D. 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；such…as 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 one's health. 如我们所知，吸烟有害健康。
As is known, smoking is harmful to one's 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。
VII. 先行词和关系词二合一
1） Whoever spits in public will be punished here. （Whoever 可以用 anyone who 代替）
定语从句练习题答案 篇三
1、 A. which用作关系代词，在定语从句中作主语。

9、 A. "谈到某事物"应说talk about sth.。about是介词，其后要用which作宾语，不能用that。
10、 A. with which是"介词+关系代词"结构，常用来引导定语从句。with有"用"的意思，介词之后只能用which,不能用that. with which在定语从句中作状语，即he is writing with a pen.
11、 C. in front of which 即in front of a farmhouse. In front of which在从句中作状语。
12、 D. with whom引导定语从句。with whom放在从句中即为:my father works with the engineer.

17、 B. as作关系代词可以单独用来引导非限制性定语从句。这时as所指代的不是主句中某个名词，而往往指代整个主句的含义。as在从句中可以作主语、宾语。从句可放在主句后，也可置于主句前。在本句中，as作宾语。
18、 B. Li Ming enjoyed it very much是主句，with whom I went to the concert是定语从句。with whom放在从句中为:I went to the concert with Li Ming.
19、 C. as引导定语从句时通常构成such.。.as或the same.。.as固定搭配，其中such和same修饰其后的名词，as为关系代词，指代其前的名词引导定语从句。 as在从句中可以作主语、表语或宾语。Such修饰单数名词时，要用such a.。.。.。.。，本题中such books, such直接修饰复数名词。

21、 D. who引导非限制性定语从句，who作从句的主语。
22、 C. two thirds of whom 即:two thirds of the 2,000 workers.
23、 D. 先行词person后有两个定语从句，第一个从句省略了关系代词whom.因为， whom作从句中met的宾语，可以省略。第二个从句who could do it.who在从句中作主语，不可省略。
24、 A. whose title引导非限制性定语从句，whose title也可以说成the title of which
25、 A. for which 引导定语从句，使用介词for,是来自于从句中的固定短语 be famous for "以。.。.。.。.而闻名"。
26、 C. 当先行词被such修饰时，引导定语从句的关系代词要用as. As在本从句中作主语。
27、 A. 两个先行词the day都是表示时间的名词，但第一个空白处要填的关系词在从句中作状语，因此要用关系副词when. 第二个空白处要填的关系词在从句中作动词spent的宾语，因此要用关系代词which或that来引导定语从句。
28、 D. 在way、distance、direction等词后的定语从句中，常用that来代替"in （或其他介词）+which"、when或where，而that常可省略。
29、 D. for which在定语从句中作原因状语，可用why 来替代。
30、 B. which I have looked after 构成一个非限制性定语从句。

43、 C. 本句话的定语从句是who own cars. 其先行词是people,因此，定语从句的谓语动词要用复数的own。本句话主句的主语是The number of指"。.。.。的数目"，是单数概念。因此，主句的谓语动词要用is。
44、 D. that followed是定语从句，关系代词that在从句中作主语。
45、 A. 先行词gas被only修饰，关系代词要用that，而不用which。
46、 B. through which引导定语从句，through which即through the hole,在定语从句中作状语。What引导的是see的宾语从句，并作从句的主语。
47、 B. 为便于理解，改写本句话：This is the school that some Germanfriends visited last week. 不难看出，作表语的the school是先行词。that引导了定语从句，因为that同时又作visited的宾语，所以被省略了。其它选项结构不对。
48、 A. 解释见35题。
49、 C. 因为是two ballpens, 并且定语从句的谓语writes是单数概念。因此，C是正确选项。
50、 B. 本句话中，主句的主语是all,为抽象概念。因此，其谓语应用单数的has been。关系代词that引导定语从句，并在从句中作主语。

英语定语从句语法解析 篇四
1. 分隔定语从句。
先行词与定语从句之间有时也会插入别的成分，构成先行词与定语从句的隔离，这种从句叫分隔定语从句。例如：
This is the article written by him that I spoke to you about.
He was the only person in this country that was invited.
①因定语从句过长，为使句子保持平衡，常将定语从句和其所修饰的名词或代词分开。
The film brought the hours back to me when I was taken good care of in that faraway village.
②在定语从句中使用“插入语”以增加语言的灵活性。
The pen I thought I had lost is on my desk，right under my nose.
2. as 和 which 引导的定语从句。
① as 有“正如，就像”之意，在非限制性定语从句中充当主语、宾语或表语，从句可位于主句的前面、中间或后面，一般用逗号与主句隔开。
As we had expected，her performance was wonderful.
A panda， as we know，is a lovely animal.
Tom is the tallest in our class，as you know.
但 which 引导的非限制性定语从句一般只能放在主句之后。例如：
The result of the experiment was very good，which we hadn’t expected.
②在主谓宾结构的非限制性定语从句中，which 和 as 作宾语时可互换使用。
He was an Englishman，which / as I knew from his accent.
作主语时通常用 which ，而不用 as 。但在“主语 +be+done ”结构中，as 作主语。例如：
He passed the examination，as was known.
③ as 引导非限制性定语从句时，通常用在表示肯定意义的从句中，而不能用在表示否定意义的从句中； which 则不受此限制。例如：
Mummy treats me just as a baby，which （不用 as ） I can’t bear.
She married again，which （不用 as ）was unexpected.
④在宾补结构的非限制性定语从句中，作主语或宾语时，宜用 which ，而不用 as 。例如：
He believed in God，which （不用 as ） I find strange.
He changed his mind，which （不用 as ） made me very angry.
⑤定语从句中动词若为表示知觉的词，如 see ，expect ，say ，know 等时，用 as 而不用 which 。
As we expected / know， Xiao Ming took the first place in the game.
⑥ as 引导的定语从句与 it 作形式主语的主语从句和以 what 引导的主语从句的区别。试比较：
As is known to everybody，the moon travels round the earth once every month.
It is known to everybody that the moon travels round the earth once every month.
What is known to everybody is that the moon travels round the earth once every month.
3. 定语从句与并列句的识别。
定语从句与主句之间要用“逗号”分隔，并且不能加入 and ， but ， so 等连接词。并列句一般由 and ， but ， so 等词连接，或中间用“分号”隔开。例如：
He paid the boy $10 for washing the windows，most of which hadn’t been cleaned for at least a year. （定语从句）
He paid the boy $10 for washing the windows，and most of them hadn’t been cleaned for at least a year. （并列句）
He paid the boy $10 for washing the windows；most of them hadn’t been cleaned for at least a year. （并列句）
Recently I bought an ancient Chinese vase，the price of which was reasonable. （定语从句）
Recently I bought an ancient Chinese vase；the price of it was reasonable. （并列句）
John’s parents kept telling him that he should work hard，but it didn’t help. （并列句）
4. that 引导的定语从句与结果状语从句的区别。
This is so interesting a book that all of us want to read it. （ so …… that 引导的结果状语从句）
This is so interesting a book as all of us want to read. （ as 引导的定语从句）
通过以上两个例句不难看出， so …… that 引导结果状语从句，而定语从句中先行词前有 so ， such ， the same 修饰时，常用“ as ”来引导定语从句。
5. 定语从句与同位语从句的区别。
同位语从句是位于名词 answer ， belief ， doubt ， decision ， explanation ， fact ， hope ， idea ， information ， news ， order ， problem ， promise ， truth 等后的句子，并对这些句词进行补充说明或解释；从句一般是一个完整的句子，引导词 that 只起引导作用，不作句子成分，且 that 不可省略；同位语从句不可用 which 引导。而定语从句通常是一不完整的句子，缺少主语或宾语等。作宾语时， that 可省略。
The fact that she hasn’t known the result of the examination is clear. （同位语从句）
The fact （that / which） she told me yesterday is very important. （定语从句）
