了解定语从句定义，熟悉关系词
正确使用关系词，运用定语从句
【基础知识】
【定语从句思维导图】
考点一 定语从句概述及关系代词引导的定语从句
一、定语从句概述
1．定义：在复合句中，修饰限定某一名词(或代词)的句子，叫定语从句。
2．先行词：被定语从句修饰的词称为先行词。
先行词一般是名词或不定代词，如：sme­， any­， every­， n­与­bdy, ­thing的合成词或all, nne, any, sme, that, thse等代词。数词和人称代词也同样可作先行词。
3．关系词：连接先行词与从句的词叫关系词。
关系代词：wh, whm, which, that, whse, as等。
关系副词：when, where, why等。
4．分类：定语从句分为限制性定语从句和非限制性定语从句两类。
区别：限制性定语从句对先行词起修饰限定作用，而非限制性定语从句对先行词起补充说明作用，先行词与定语从句往往由逗号隔开。试比较：
eq \b\lc\{\rc\ (\a\vs4\al\c1(He has tw sns， wh wrk in the same cmpany.,他有两个儿子，他们在同一公司上班。（他只有两个, 儿子）,He has tw sns wh wrk in the same cmpany.,他有两个儿子在同一公司上班。/他有两个在同一, 公司上班的儿子。（可能不止有两个儿子）))
5．功能：相当于形容词，修饰名词或代词，在句中作定语。
6．位置：定语从句常置于被修饰词之后；as引导的非限制性定语从句可置于主句前、句中，也可置于主句之后。
①Thse wh are fr the plan raise yur hands, please.
请支持这个计划的人举手。
②As is knwn t us all, the earth is spinning arund the sun.
我们都知道，地球围绕太阳旋转。
二、关系代词引导的定语从句
引导定语从句的关系代词有：that, which, wh, whm, whse, as等，关系代词可作主语、宾语、定语等。
1．wh, whm, that这些词代替的先行词是表示人的名词或代词，在从句中可作主语、宾语等。
I've made gd friends with several f the students in my schl wh/whm/that I met in the English speech cntest last year.
我已与去年在英语演讲比赛中遇到的我校的几个学生结交为好朋友。
2．whse既可指人又可指物，在定语从句中作定语。指物时，“whse＋名词”可用“the＋名词＋f which”或“f which＋the＋名词”来代替。
①D yu knw the by whse handwriting is very beautiful?
你认识那个书法非常漂亮的男孩吗？
②I'd like a rm whse windw lks ut ver the sea.
→I'd like a rm, the windw f which lks ut ver the sea.
→I'd like a rm, f which the windw lks ut ver the sea.
我想要一个窗户朝向大海的房间。
3．which, that所代替的先行词是表示事物的名词或代词，在从句中可作主语、宾语等。
①He was reading a bk which/that was abut war.
他正在读一本关于战争的书。
A：指物时，关系代词that和which一般情况下可换用，但以下几种情况下一般用that，而不用which。
(1)先行词是all, everything, smething, anything, nthing, nne, few, little, much等不定代词，或先行词被all, every, sme, any, n, few, little等修饰时。
②I have read all the bks (that) yu gave me.
你给我的所有书我都已经读过了。
[注意] 当smething确指某物或某事时，用that或which都可以。
This is smething that/which yu might have frgtten.
这事你可能已经忘记了。
(2)先行词被形容词的最高级或序数词(如：the first，the secnd, ...，the last等)修饰时。
③This is the best film (that) I have ever seen.
这是我看过的最好的电影。
(3)先行词被the nly, the very, the right等修饰时。
④The nly thing that matters is t find ur way hme.
唯一要紧的事情是找到我们回家的路。
(4)先行词既有人又有物时。
⑤They talked abut the persns and things (that) they remembered in the schl.
他们谈论起他们记得的学校里的人和事。
B：在以下情况中，只能用which，不能用that。
(1)在非限制性定语从句中，如果从句中缺少主语或宾语，并指物，只能用which。
⑥Our ftball team wn the final, which made us excited.
我们的足球队赢得了决赛，这使我们非常兴奋。
(2)关系代词充当介词的宾语，且介词位于关系代词之前时，只能用which。
⑦The huse in which I used t live has becme a she shp.
过去我居住的房子已变成了一家鞋店。
[注意] 使用关系代词时，注意两点：
(1)先行词是“人”还是“物”；
(2)关系代词在定语从句中充当主语或宾语，且在从句中作宾语时可以省略。(非限制性定语从句中的关系代词不可以省略。)
4．as引导的定语从句
A：as作为关系代词，在定语从句中缺少主语或宾语时使用，通常先行词由the same, as, such, s等修饰时，关系代词用as。
①They culd nly read such stries as had been rewritten in simple English.(as作主语)
他们只能读类似这样的一些用简易英语改写的故事。
②These huses are sld at such a lw price as peple expected.(as作宾语)
这些房子以人们期望的低价出售。
③This is the same knife as I lst.(as作宾语)
这把小刀和我丢的那把很相似。
[注意] such ... as ... 与such ... that ... 的区别
such ... as ... 中的as引导的是定语从句，而such ... that ... 中的that引导的是结果状语从句。当as引导定语从句时，as在从句中一般作主语或宾语，而that引导结果状语从句时，that在从句中不作任何成分。
This is such a difficult prblem as mst f us can't wrk ut.
这是一个我们大多数人都不能解决的难题。
(从句中的wrk ut缺少宾语，前面的as是关系代词，用作wrk ut的宾语。)
She is such a kind girl that many students like her.
她是个善良的女孩所以很多学生喜欢她。
(状语从句是完整的句子，前面的that只起引导从句的作用，在从句中不作成分。)
B：关系代词as与which引导非限制性定语从句的区别
(1)位置不同
as引导的非限制性定语从句可以置于主句之前、之中或之后，而which引导的非限制性定语从句只能位于主句之后。
④As is ften the case, little bys tend t be very active and ut f cntrl.
小男孩总是很活泼好动，很难控制，这是常见的情况。
⑤Einstein, as is well knwn, is a famus scientist.
众所周知，爱因斯坦是一位著名的科学家。
⑥There was a bank arund here, as I remember.
我记得过去这儿附近有一家银行。
⑦He failed in the exam, which was unexpected.
他考试没及格，这是意料之外的。
(2)意义不同
as常译作“正如，像”，多用于下列习惯用语中：as anybdy can see “正如人人都能看到的那样”；as is well knwn＝as is knwn t all “众所周知”；as we had expected “正如我们所预料的那样”；as ften happens “正如经常发生的那样”；as is ften the case “正如经常发生的那样”；as has been said befre “如上所述”；as is mentined abve “正如上面提到的”；as I remember “正如我所记得的那样”。which常译作“这一点，这件事”，此时指前面主句所提到的那件事。
⑧He ppsed the idea, as culd be expected.
不出所料，他反对这个意见。
⑨Tm has made great prgress, which makes his parents very happy.
汤姆进步很大，这使他父母很高兴。
(3)用法不同
a．当非限制性定语从句是否定句或表示否定意义时，只能用which。
⑩He came here very late, which was unexpected/nt expected.
他来得很晚，这是未预料到的。
b．当as在句中作主语时，后常接动词的被动语态，如：be knwn, be said, be reprted等。如果从句中动词是主动语态，一般用which作主语。
⑪She has been absent again, as is expected.
她又缺席了，正如预料的那样。
考点二 关系副词引导的定语从句
当定语从句中不缺少主语、宾语、定语和表语时，要选用关系副词。其中when, where, why是常见的三个关系副词。
when＝表时间的介词(如：in, n, at, during等)＋which；
where＝表地点的介词(如：in, at, n, under等)＋which；
why＝表原因的介词(如：fr)＋which。
1．关系副词when, where, why的先行词是表示时间、地点或理由的名词，关系副词在从句中作状语。
①Nwadays peple are mre cncerned abut the envirnment where they live.
现在人们更加关心他们居住的环境。
②I'll never frget the day when my sn was brn.
我永远忘不了我儿子出生的那一天。
[注意] （1）当先行词为一些表示抽象地点的名词，如：pint， situatin， case， stage， family等时，如果引导词在从句中作状语，常用关系副词where引导定语从句；如果不作状语，则用关系代词that/which。
Remember that there is still ne pint that/which we must make clear at the cnference tmrrw.
记住在明天的会议上我们还有一点必须弄清楚。
She's in a hpeless situatin， where we will keep a very clse eye n her.
她处于无望的处境中，在这种情况下我们将密切注意她。
（2）先行词ccasin当“时刻”讲时，用关系副词when；当“场合”讲时，用关系副词where。
Please describe an ccasin where yu met real difficulties.
请描述你遇到真正困境的场景。
Occasins are rare when I have the time t spend a day with my kids.
我有时间和孩子们度过一天的时机很少。
2．way和time后接定语从句的情况。
(1)当先行词是way(意为“方式、方法”，且关系词在定语从句中作状语)时，引导定语从句的关系词可以是that, in which或省略。
①I dn't like the way (that/in which) he lks at me.
我不喜欢他看我的方式。
(2)先行词是time时，若time作“次数”讲，应用关系代词that引导定语从句，that可省略；若time作“一段时间，时代”讲，应用关系副词when或“介词at/during＋which”引导定语从句。
②This is the first time (that) I have talked with a freigner face t face.
这是我第一次和一个外国人面对面交流。
③There was a time when I hated ging t schl.
曾经有一段时间我讨厌上学。
考点三 “介词＋which/whm”引导的定语从句掌握“介词＋关系代词”引导的定语从句，要注意以下几点：
1．关系代词的确定
在介词后作宾语的关系代词只有which和whm。如果先行词是物，引导词用which；如果先行词是人，则引导词用whm。
①This is the train n which I went t Shanghai.
这就是我去上海所乘坐的那列火车。
②This is the student fr whm I bught the dictinary.
这就是我为他买词典的那个学生。
[注意] 介词一般放在关系代词which和whm之前，如果介词和句中动词组成固定词组时，这个介词一般不前置。
My yungest brther， whm I have t lk after， is demanding.
我得照看我最小的弟弟，他真是让人费神。
2．关系代词前介词的确定
(1)依据定语从句中动词或形容词的习惯搭配来确定。
①The fellw t whm I spke made n answer at first.
我与之说话的那个人起初没有回答。(speak t)
②The West Lake, fr which Hangzhu is famus, is a beautiful place.
西湖是一个美丽的地方，杭州因此而闻名。(be famus fr)
(2)根据先行词来确定。
③I'll never frget the time during which I spent my childhd in the cuntry.
我永远不会忘记我在乡村度过的童年时光。(during the time)
④Air, withut which man can't live, is really imprtant.
空气真的很重要，没有它人类就不能生存。(withut air)
3．“名词/代词＋介词＋关系代词”结构
此类结构常见的有“sme/many/mst/all/nne＋f＋which/whm”等。
①Here are the questins, sme f which I think are difficult fr yu.
问题都在这儿，其中一些我认为对你来说很难。
②He has three sns, nne f whm are dctrs.
他有三个儿子，没有一个是当医生的。
4．“复合介词短语＋关系代词which”引导的定语从句，其从句部分常与先行词用逗号隔开，且从句部分常用倒装语序。
He lived in a big huse, in frnt f which std a big tree.
他住在一所大房子里，房子前面有一棵大树。
5．“介词＋which/whm＋不定式”结构
The pr man has n huse in which t live.
→The pr man has n huse t live in.
→The pr man has n huse in which he can live.
那个穷人没房子住。
[注意] 有时为表达清楚，也可以在关系副词where/when前加介词frm/t等，平时也应掌握，但非高考重点。
China is the birthplace f kites， frm where kite flying spreads t Japan， Thailand， India and s n.
中国是风筝的发源地，从这里，放风筝传到了日本、泰国、印度等国家。
误区一 关系词的漏用或关系词的误用
(1)【误】There are many peple think that wealth is better than health.
【正】There are many peple wh/that think that wealth is better than health.
【正】There are many peple thinking that wealth is better than health.
[分析] 此句是there be句型，故判断“think that ...”用作定语；先行词是peple，从句中缺少主语，故用wh/that引导定语从句，相当于现在分词thinking。
(2)【误】I still remember the days when I spent with farmers in the cuntryside.
【正】I still remember the days (that/which) I spent with farmers in the cuntryside.
[分析] 先行词是the days，从句动词spent缺少宾语，故用关系代词that/which引导定语从句，并在从句中作宾语，可省略。
(3)【误】All the bks which were brrwed frm the library must be returned n time.
【正】All the bks that were brrwed frm the library must be returned n time.
[分析] 当定语从句的先行词被all, sme, any, n, few等修饰时，关系代词用that。
(4)【误】Until nw, we have raised 50,000 punds fr the pr children, wh is quite unexpected.
【误】Until nw, we have raised 50,000 punds fr the pr children, as is quite unexpected.
【正】Until nw, we have raised 50,000 punds fr the pr children, which is quite unexpected.
[分析] 考查非限制性定语从句，先行词并非children，而应为整个主句所述的内容，另as在引导非限制性定语从句时，常用于肯定，而which可用于否定，故本题应用which来引导非限制性定语从句。
[注意] 造成以上错误主要因为以下几点：
（1）对先行词判断不准，特别是当先行词被其他句子成分分离开时。
（2）不清楚关系代词和关系副词的区别。
（3）不了解特殊关系词的区别，如关系代词as与which， that与which的区别。
针对以上错因，可从以下几方面着手：
（1）准确判断先行词，解题时，如遇过长过繁的句子，应学会简化，将干扰项移除。
（2）找对先行词后，将其代入定语从句，一般而言，代入之后，不需加介词的，应用关系代词来引导从句，而需要加介词的，则用关系副词来引导。
（3）加强基础知识的学习，如：关系词何时可省略，特殊先行词之后的定语从句，特殊关系词的用法区别等。
误区二 关系代词与替代词的重复或与普通代词的误用
(1)【误】He was the lst by that his parents were lking fr him everywhere.
【正】He was the lst by that his parents were lking fr everywhere.
[分析] 定语从句中关系代词作从句中动词lk fr的宾语，而him与关系代词that指代的内容重叠，均是the lst by，因此him多余，需删除。
(2)【误】They were deeply mved, mst f them were with tears in their eyes.
【正】They were deeply mved, mst f whm were with tears in their eyes.
【正】They were deeply mved, and mst f them were with tears in their eyes.
【正】They were deeply mved, mst f them with tears in their eyes.
[分析] 分析句式可知，此处是“介词＋关系代词”型的定语从句，先行词指人，故用whm引导定语从句。此句还可以改为并列句或独立主格形式。
[注意] 造成以上错误主要是由于几个方面掌握不牢而致。
(1)关系代词的作用：既指代先行词又起连接句子的作用，因此关系代词与指代同为先行词的代词不能重复出现在定语从句中。
(2)定语从句的定义：在复合句中，修饰某一名词或代词的句子叫作定语从句，定义中要求把握几点：首先要有主句，其次关系词引导的为从句，再次从句要修饰主句中的某个名词或代词，因此要知晓定语从句与并列句或其他句式的区别，才能避免错误的发生。
误区三 定语从句中主谓不一致或与其他结构的误用
(1)【误】This is ne f the rms that was damaged in the fire.
【正】This is ne f the rms that were damaged in the fire.
[分析] 句意：这个房间是那次大火中被烧毁的房间之一。在ne f ... 结构中，先行词为f后的复数名词或代词，从句谓语用复数形式。但当先行词是“the nly/very ne f＋复数名词”时，从句谓语则用单数形式。比较：
This is the nly ne f the rms that was damaged in the fire.
这就是那次大火中唯一一个被烧毁的房间。
(2)【误】The university in France that I am applying fr having its wn requirement.
【正】The university in France that I am applying fr has its wn requirement.
[分析] 此题中that I am applying fr为定语从句，修饰先行词the university。该句主语为the university，缺少谓语，且谓语动词应用第三人称单数形式。
[注意] 造成以上错误一是由于对先行词，特别是特殊先行词把握不好，二是定语从句起了干扰作用。因此在解题时，首先要找对先行词，并要学会简化句式结构，化繁为简，这需要我们在平时训练时多分析、多积累。
误区四 定语从句与强调句型结合考查时造成的误用
【误】Culd it be in the restaurant that yu had dinner with me yesterday where yu lst yur handbag?
【正】Culd it be in the restaurant where yu had dinner with me yesterday that yu lst yur handbag?
[分析] 本句中where引导的为定语从句，而that为强调句型中的连接词，如颠倒误用则导致句子结构混乱、语义不明。
[注意] 造成以上错误主要是因为定语从句与强调句型结合考查时，不能进行分辨而致。在解此类题型时，要首先判断哪一部分为强调句型（强调句型强调的是句子中的一个完整成分，详参本书“特殊句式”部分），然后再判断是否为定语从句。
1．若两个句子中间无连词，且跟在名词或代词后，则很可能考查定语从句中的关系词。
2．判断从句中是否缺主语、宾语、定语，如果缺少，则填关系代词。考虑：①先行词是表示人还是物；②先行词是否有特殊情况。
3．若从句中不缺少主语、宾语、定语成分，则要填关系副词或考虑“介词＋which/whm”(注意介词后只能填which/whm)。
[注意] (1)从句中缺少宾语的情况无外乎两种：
①介词＋宾语 ②及物动词＋宾语
所以对从句中存在介词或及物动词的情况要引起高度重视。
(2)what不引导定语从句；that不引导非限制性定语从句，不用在介词之后引导定语从句。
【考点剖析】
The Chinese Ministry f Agriculture finds that between 2005 — when the gvernment started a sil-testing prgram ________ gives specific fertilizer recmmendatins t farmers — and 2011, fertilizer use drpped by 7.7 millin tns.
【答案】that/which
【解析】句意：2005年政府开始了一个土壤测试的项目，给农民推荐特定的化肥。中国农业部发现在2005年至2011年间，化肥的使用减少了770万吨。分析句子结构可知，空格处引导定语从句，先行词是a sil-testing prgram，指物，且定语从句中缺少主语，故填关系代词that或which。

【解析】 purpses与the Wrld Fd Prgramme存在“所属”关系，此处指“世界粮食计划署的目的之一”，且空处在句中作定语，因此填whse。
The little prblems ________ we meet in ur daily lives may be inspiratins fr great inventins.
【答案】that /which
【解析】句意：在日常生活中我们遇到的小问题可能是伟大发明的灵感来源。根据句意并分析句子结构可知，“________ we meet in ur daily lives”为定语从句，修饰先行词prblems，且从句缺少宾语，所以用关系代词that /which。
【真题演练】

【过关检测】
Written Chinese has als becme an imprtant means by ________ China’s present is cnnected with its past.
【答案】which
【解析】句意：书面汉语也成了一种重要的手段，通过它，中国的现在与过去被连接了起来。先行词为means，将先行词代入定语从句后为：China’s present is cnnected with its past by this means.由此可知，关系词在定语从句中作介词by的宾语，介词by被提前，故填which。
