定语从句考点
英语定语从句考点重点归纳总结
英语定语从句考点重点归纳总结定语从句是英语语法中的一个重要部分，它在句子中起到修饰名词或代词的作用。
掌握定语从句的用法和特点对于英语学习者来说至关重要。
本文将对英语定语从句的考点进行重点总结和归纳。
一、定语从句的引导词1.关系代词：关系代词常用于引导定语从句，包括that，which，who，whom，whose等。
2.关系副词：关系副词也可以引导定语从句，主要包括when，where，why等。
二、定语从句的作用和位置定语从句通常用来修饰名词或代词，它可以紧跟在被修饰的名词或代词之后，也可以放在句子的末尾。
如果定语从句紧跟在被修饰的名词或代词之后，通常用关系代词来引导；如果放在句子末尾，则用关系代词或关系副词来引导。
三、定语从句的几种类型分析1.限定性定语从句：限定性定语从句是定语从句的一种常见形式，它对被修饰的名词起到了限定和具体化的作用，去掉定语从句，句子的意思仍然完整。
关系代词在从句中作主语、宾语或定语，关系副词在从句中修饰时间、地点或原因。
2.非限定性定语从句：非限定性定语从句是用来对被修饰的名词进行补充说明或者陈述一些额外信息的。
非限定性定语从句通常用逗号或者破折号与主句隔开，去掉定语从句对整个句子的意思没有太大影响。
四、定语从句的连接词使用注意事项1.关系代词that和which的区别：that通常用来引导限定性定语从句，which则常用于非限定性定语从句。
2.关系代词who和whom的区别：who用来引导指人的定语从句，并在从句中担任主语或者宾语；whom通常用于非限定性定语从句，担任宾语。
3.关系代词whose的用法：whose用来引导定语从句，表示所属关系。
5.关系副词when，where和why的用法：when用来表示时间，where表示地点，why表示原因。
五、定语从句的注意事项1.省略关系词：当关系从句中作主语、宾语或者介词宾语时，关系词（常用的是that或which）可以省略。

关于定语从句的六大考点(真题+解析)
关于定语从句的六大考点（真题+解析）
考点一which和as引导的非限制性定语从句
①which常用来指代前面的名词或整个句子的内容，一般情况下，用逗号把它与先行词隔开。
先行词指代整个主句时，从句谓语动词要用第三人称单数。
【考例1】He wrote many children’s books, nearly half of _________ were published in the 1990s.
(2015重庆)
A. whom
B. which
C. them
D. that
解析：B。
which指代前文中提到的children’s books。
【考例2】 I borrowed the book Sherlock Holmes
from the library last week, _________ my classmates recommended to me.
(2014北京)
A. who
B. which
C. when
D. where
解析：B。
先行词为the book Sherlock Holmes，从句中recommend后缺少宾语成分，故用关系代词which引导。
②as可以替代which的用法，且as还有下列用法：as从句可放到主句前面，此时从句谓语动词一般为be
announced/expected/known/reported/said/imagined/shown等被动形式；as也可与usually happened/be often the case等一起表示主句所表达的意思是一种习惯性或司空见惯的情况。

定语从句知识点总结(热门3篇)
定语从句知识点总结第1篇一、省去作主语的关系代词致错误：The changes have happened in the past few years make the city look even more beautiful.正：The changes that have happened in the past few years make the city look even more beautiful.误：Those want to visit the art exhibition sign your names，please.正：Those who want to visit the art exhibition sign your names，please.分析：关系代词在定语从句中作宾语时可以省，但作主语时不能省。
二、从句中使用多余的代词或副词致错误：The compositions we handed them in two weeks ago haven’t been marked yet.正：The compositions we handed in two we eks ago haven’t been marked yet.分析：从句中省去了作宾语的关系代词that或xxxch，应去掉them。
误：After living in Paris for 60 years，he returned to the small town where he grew up as a child there.正：After living in Paris for 60 years，he returned to the small town where he grew up as a child.分析：关系副词where在从句中作地点状语，xxxhere属语义重复，应去掉。
三、as / it / xxxch混用致错误：As is known to all that smoking does great harm to health.正：It is known to all that smoking does great harm to health.或As is known to all，smoking does great harm to health.分析：as引导非限制性定语从句，置于句首时，要用逗号与主句隔开;it放在句首，作形式主语时，将从句后置，中间不用逗号。
高中定语从句知识点归纳
高中定语从句知识点归纳一、定语从句的概念定语从句是在句子中起定语作用的句子。
它修饰主句中的某个名词或代词，被修饰的名词、代词叫先行词，定语从句总是放在先行词之后，且引导定语从句的关联词必须放在定语从句之首。
二、定语从句的关系词引导定语从句的关系词有关系代词和关系副词，常见的关系代词包括that，which，who（宾格whom，所有格whose）等，关系副词包括where，when，why等。
关系代词和关系副词放在先行词及定语从句之间起连接作用，同时又作定语从句的重要成分。
三、定语从句的分类根据定语从句与先行词的关系，定语从句可分为限制性定语从句及非限制性定语从句。
限制性定语从句紧跟先行词，主句与从句不用逗号分开，从句不可省去。
非限制性定语从句与主句之间有逗号分开，起补充说明作用，如省去，意思仍完整。
四、关系代词的用法1.that 既可以用于指人，也可以用于指物。
在从句中作主语、宾语或表语。
作主语时不可省略，作宾语可省略。
例如：Mary likes music that is quiet and gentle.（玛丽喜欢轻柔的音乐。
）2.which用于指物，在句中作主语、宾语或表语。
作主语不可省略，作宾语可省略。
例如：The building which stands near the train station is a supermarket.（位于火车站附近的那座大楼是一家超市。
）3.who，whom用于指人，who 用作主语，whom用作宾语。
在口语中，有时可用who代替whom。
who和whom作宾语时也可省略。
例如：The girl who often helps me with my English is from England.（经常在英语方面帮助我的那个女孩是英国人。
）4.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。
初中阶段定语从句的相关用法或考点
初中阶段定语从句的相关用法或考点1. 嘿，你知道定语从句里关系代词和关系副词的区别吗？就像钥匙和锁一样，得配对才行呀！比如“She lives in a house where I used to live.”这里的“where”就是关系副词啦。
2. 哇塞，定语从句里先行词可重要啦！先行词就像是将军，后面的定语从句就是跟着它打仗的士兵呢！像“He is the man that I saw yesterday.”中“the man”就是先行词哦。
3. 哎呀呀，什么时候只能用 that 不能用 which，这可得搞清楚呀！这就好比有些场合只能穿正装不能穿休闲装一样。
像“All that glitters is not gold.”就得用 that 呀。
4. 嘿嘿，定语从句中的省略情况呢，你了解不？这就像有些话不用说全大家也能懂一样！比如说“He is the man I saw (whom).”括号里的就可以省略呢。
5. 哇哦，怎么判断定语从句修饰的是谁呀？这就像找对目标一样重要！比如“In the classroom there are many students who are studying.”很明显就是修饰 students 啦。
6. 哎呀，定语从句和其他从句混淆了可咋办？这就像把张三认成李四一样糊涂呢！比如“If the weather is fine tomorrow, we will go out.”这可就不是定语从句哦。
7. 哈哈，掌握了定语从句的用法是不是感觉很有成就感呀？就像解开了一个难题一样开心呢！想想看“She is the girl who has a beautiful smile.”，多棒呀！我的观点结论：初中阶段学好定语从句真的很重要呀，能让英语表达更丰富准确呢！。
定语从句重要考点汇总
定语从句重要考点汇总一、定义与总括复合句中修饰名词和代词的从句叫定语从句，被修饰的名词或代词叫先行词。

三、限制性定语从句与非限制性定语从句的区别：四、引导词之间的区别：（一）that与which, that与who之间的用法区别1. 在定语从句中，当先行词指物时，下列情况的关系词宜用that而不用which，who（1）当先行词前被the only、any、few、little、no、all、the very（正好，恰恰）等词修饰时。

Eg. Do you have anything that you want to say for yourself?You should hand in all that you have.We haven’t got much that we can offer you.（3）当先行词是形容词最高级或先行词的前面有形容词最高级修饰时。
Eg. This is the best that has been used against pollution.This is the most interesting film that I’ve ever seen.English is the most difficult subject that you will learn during these years.（4）当先行词是序数词，或先行词前有序数词修饰时。
定语从句九大考点-ok

①whose引导定语从句，其后应紧跟名词，构成名 词短语。 ② whose与它所修饰的名词一起可以作介词的宾语。 如： The boss in whose department he worked had heard the news.他工作所在部门的老板已经听说 了这个消息。
③ whose引导的定语从句，其先行词既可以指人 也可以指物。
with which • This is the pen ________ _______ I wrote the letter. • Is that the girl ________ ________ to whom you lent your bicycle?

高考定语从句八个考点
高考定语从句八个考点定语从句是英语学习的一个重要语法项目;也是历年高考在具体的语境中考查考生灵活运用知识能力的一个重点..为了帮助同学们更好地掌握这一语法项目;本文结合近几年的高考试题;分析、探究定语性从句的考查;对其考查归纳为以下八个考点..一、考查非限制性定语从句中的which在非限制性定语从句中;which既起连接的作用;又在从句中充当一定的句子成分主语、宾语或表语;放在主句之后;指代整个主句或主句中的部分内容..经典题赏析1. My friend showed me round the town; _______was very kindof him.09全国卷IIA. whichB. thatC. whereD. it解析:本题考查非限制性定语从句的关系代词的用法;选项中只有which可指代前面一个句子;并引导从句;it虽然可代替前面句子;但不能起连接的作用;故答案为A..2. The Science Museum; _______we visited during a recent tripto Britain; is one of London’s tourist attractions. 08江苏A. whichB. whatC. thatD. where解析:引导非限制性定语从句时;which在从句中可以作宾语;指代主句的主语“The Science Museum”;而where只能作状语..故答案为A..3. Chan’s restaurant on Baker Street; ______ use d to be poorlyrun; is now a successful business. 07浙江A. thatB. whichC. whoD. where解析:该题逗号之间为非限制性定语从句;从句中缺少主语;所以选项范围应是关系代词;排除掉关系副词where;而that不可以引导非限制性定语从句; 只有which可指代前面的China’s restaurant..故答案为B..小结非限制性定语从句中;判断选which还是where; when;关键在于分析定语从句的主干结构是否完整;如果该从句的先行词是物;从句中缺少主语、宾语或表语;通常要用which;如果从句中缺少状语;则用when或where..事实上;非限制性定语从句可理解成是某一并列句的转换..如:例1可理解为:My friend showed me round the town; and it was very kind of him.二、考查关系副词;尤其是where的考查关系副词where; when在定语从句中既起连接作用;同时又在从句中充当状语;分别表地点、时间..选用关系副词的关键是要求正确分析从句主干结构;选词必须符合句子的逻辑意义..经典题赏析1. It’s helpful to put children in a situation _______ theycan see themselves differently. 09福建A. thatB. whenC. whichD. where解析:由于从句的主谓宾结构完整;只能选用状语;由先行词 a situation可知;应选用作地点状语的where 引导定语从句..故答案为D..2. They will fly to Washington; _______ they plan to stay fortwo or three days. 08重庆A. whereB. thereC. whichD. when解析:首先排除地点副词there; there不能引导从句;如果用there;后半句要改为and they plan to stay there for two or three days..由先行词“Washington”可知从句的关系词表地点;并且stay缺少状语;所以应该用where连接主从句..故答案为A..3. Today; we’ll discuss a number of cases_______ beginnersof English fail to use the language properly. 07陕西A. whichB. asC. whyD. where解析:此定语从句主谓结构完整; 缺少状语;考虑到先行词cases;选用关系词where;相当于in which= in the cases..故答案为D..小结从以上高考试题可以看出对于where引导的定语从句;先行词既可是明确的地点;也可是“模糊化的地点”..如表示某人 / 物的situation;或某事所发展的stage都可用where这个关系副词..三、考查关系代词whosewhose在定语从句中充当名词的定语;构成“whose + 名词”的形式;既可以表示某人的;又可以表示某物的..其最显着的特点是空格后的名词缺少限定词..经典题赏析1. A person ______ e-mail account is full won’t be able tosend or receive any e-mails.09天津A. whoB. whomC. whoseD. whoever解析:who和whom只可做定语从句的主语或宾语；whoever引导名词性从句；而 A person作定语从句的先行词;从句中作主语的e-mail account缺少限定词;whose可充当名词的定语..故答案为C..2. Look out Don’t get too close to the house_______roof isunder repair. 06福建A. whoseB. whichC. of whichD. what解析:定语从句中作主语的roof缺少限定词;即定语;选择whose 充当定语..而of which在这里无法与the roof搭配..故答案为A..小结在定语从句中;对于事物的所属关系;可以使用以下三种形式:whose + 名词;the + 名词 + of which 或of which the + 名词..四、考查介词 + which或whom介词后接关系代词;在从句中可以作定语或状语;如果先行词是人;关系代词用whom;如果先行词是物;关系代词用which..对于介词的选用则要综合考虑..经典题赏析1. Gun control is a subject _______Americans have argued fora long time. 09陕西A. of whichB. with whichC. about whichD. into which解析:该题从句谓语argued与介词about搭配表达“争论某事”;故答案为C..2. By nine o’clock; all the Olympic torch bearers had reachedthe top of Mount Qomolangma; _______ appeared a rarerainbow soon.08福建A. of whichB. on whichC. from whichD. above which解析:此定语从句的先行词是the top;从句的正常语序应该是:“A rare rainbow soon appeared ______ the top of Mount Qomolangma”..显然应该填上“above”;表示山顶上..所以用above which连接主从句..故答案为D..3. We shouldn’t spend our money testing so many people; mostof _______are healthy. 07北京A. thatB. whichC. whatD. whom解析:由于先行词为so many people;关系代词只能用whom引导非限制性定语从句..所以答案为D..小结从以上句子可以看出;“介词+which / whom +定语从句”这一考点;既考查学生的定语从句知识;又可考查学生对动词短语的掌握..解此类题的关键是把先行词代入相关定语从句中;根据定语从句谓语动词的习惯搭配或与先行词的关系、或由句子表达的整体句意来确定..五、考查定语从句中的分隔一般来说;定语从句总是紧跟在它所修饰的先行词后;但有时;定语从句和先行词常常被介词或其它成分分隔;干扰了句子结构的判断;从而给辨别从句带来一定的难度..经典题赏析1. She’ll never forget her stay there_______she f ound her sonwho had gone missing two years before. 09四川A. thatB. whichC. whereD. when解析:此题的关键在于看出there分隔了先行词her stay和关系词引导的定语从句..根据先行词her stay表示“她呆的期间”及从句的句意;可知所选词须是作时间状语的连词来引导..故答案为D..2. Occasions are quite rare ______ I have the time to spenda day with the kids. 08山东卷A. whoB. whichC. whyD. when解析:此句为了保持句子平衡;避免引起主句头重脚轻;构成了先行词occasions和从句被主句的系表结构分隔现象..先行词occasions表时间;而且后面的定语从句缺少时间状语;所以应该用when或on which连接..故答案为D..3. —Is that the small town you often refer to—Right; just the one_______you know I used to work for years. 05福建A. thatB. whichC. whereD. what解析:此题中关系词和其引导的从句的主谓结构被插入语“you know”分隔;从句中主谓语结构完整;缺少地点状语..故答案为C..六、考查关系代词asas作关系代词主要用于非限制性定语从句指代整个主句;在从句中通常做主语或宾语;其引导的定语从句可以放在主句之前、主句之后或主句之间..经典题赏析1. The Beatles; _______ many of you are old enough to remember;came from Liverpool. 07天津A. whatB. thatC. howD. as解析: 本句主谓语之间插入一个非限制性定语从句;选项中只有as可引导该从句;并作从句中to remember的宾语..故答案为D..2. ________ I explained on the phone; your request will beconsidered at the next meeting.05浙江A. WhenB. AfterC. AsD. Since解析:本句是关系代词as引导的非限制性定语从句;并在从句中作explained的宾语;而其它三个选项引导句意完整的状语从句..故答案为C..七、考查定语从句与并列句、其它从句、强调句型的辨析学生常常由于不能理解和掌握同一个连词的不同功能导致对定语从句与状语从句、名词性从句、强调句或并列句等相混淆..经典题赏析1. —What do you think of teaching; Bob—I find it fun and challenging. It is a job _______you are doing something serious but interesting. 09北京A. whereB. whichC. whenD. that解析:此题很容易选that;误认为是强调结构“It is ... that”;当把该结构取掉后;剩下的部分却不成立..事实上;a job是先行词;从句主谓宾完整;缺少的只能是地点状语;因此答案为A..2. The doctor advised Vera strongly that she should take aholiday; but _______ didn’t help. 05全国ⅢA. itB. sheC. whichD. he解析:该题易误选为which;因为忽视了并列连词but后连接简单句;代词it 的用法之一就是代替前面所指内容..故答案为A..3._______is reported in the newspaper; talks between the twocountries are making progress. 04北京A. ItB. AsC. ThatD. What解析:该题学生容易忽视逗号的作用而误选为It;而It作形式主语时;逗号应改为that引导词即:It is reported ... that talks.... 如果用What表达此句意时;全句应改What isreported ... is that talks .... 而关系代词As可以指代逗号后的整个主句;引导非限制性定语从句..此题考查非限制性定语从句中as的用法;又考查了对定语从句与名词性从句的掌握..所以此类题综合性非常强;难度较大..八、考查关系代词的省略关系代词that; whom; which在限定性定语从句中作宾语时;在口语中常可以省略..经典题赏析1. The house I grew up_____ _has been taken down and replacedby an office building. 09江西A. in itB. inC. in thatD. in which解析:本题题干中The house后省略了作宾语的关系代词that;which..定语从句只缺少介词in..故答案为B..2. —Why does she always ask you for help—There is no one else _______ ; is there 05北京A. who to turn toB. she can turn toC. for whom to turnD. for her to turn解析:该题中的no one else后面省略了作宾语的关系代词whom 或who;习惯短语“turn to”表示“向某人求助”;故答案选B..小结在某一名词或代词后出现从句;题干中又没出现连词时;通常省略的是that;解题时加上that;会有助于清晰地理解整个句子结构..不妨试一试总之;在做定语从句相关试题的时候;我们首先要判断出来该句是否是一个定语从句;其次找出先行词;并看从句中是否缺少成分..准确的分析句子的成分是能否做对试题的关键..事实上;定语从句在高考各个题型中都有涉及;掌握定语从句对于语言理解和运用都具有重要的意义..链接高考试题1.

专题01定语从句100题(考点串讲)
专题01 定语从句100题★定义：定语从句是用来修饰某一名词或代词的从句。
★先行词：被定语从句修饰的名词或代词叫先行词。
通常情况下，引导词前面的名词即为从句的先行词。
★关系词：引导定语从句的词叫关系词。
也可以称作引导词。
①关系代词：who，whom，which，that，whose，as，在从句内作主语、宾语等名词性成分。
①关系副词：when，where，why在从句内作状语。
★分类：定语从句分为限制性定语从句和非限制性定语从句。
（一）关系代词：who、whom、which、that、whose、as考情：定语从句是语法填空的常考点，必须重视。
具体考点有：1. 先行词是人时，用who。
2. 先行词是物时，用which。
3. 当先行词与从句中某个名词有所属关系，表示“……的”之意，用whose。
4. 引导非限制性定语从句且指物用which。
引导非限制性定语从句且指人用who。
5. 先行词是表示时间或地点的词，在从句中作状语时，分别用when和where。
解法：首先判断是否为定语从句，是限制性定语从句还是非限制性定语从句；然后看先行词是人、是物还是整个主句；再看代表先行词的关系词在定语从句中作何种句子成分，最后再确定填哪个关系词。

英语定语从句考点重点归纳总结
英语定语从句考点重点归纳总结定语从句是英语中非常重要的语法结构之一，它可以用来修饰名词或代词，增强句子的表达能力。
在英语学习中，掌握定语从句的使用方法和特点是非常重要的。
本文将对英语定语从句的考点进行重点归纳总结。
一、定语从句的引导词：1. 关系代词在定语从句中，我们通常使用关系代词来引导定语从句，包括：that, which, who, whom, whose。
它们在从句中充当主语、宾语、定语等成分。
2. 关系副词除了关系代词，有时也会使用关系副词来引导定语从句，包括：where, when, why。
它们在从句中表示地点、时间和原因。
二、关系代词的使用：1. that在定语从句中，that 可以引导限定性定语从句和非限定性定语从句。
一般来说，that 引导的定语从句可以修饰人和物。
2. whichwhich 引导的定语从句可以修饰物，常用于非限定性定语从句中，表示补充说明。
3. who/whomwho 引导的定语从句用于修饰人，并且在从句中充当主语。
如果在从句中充当宾语，则需要用 whom。
4. whosewhose 引导的定语从句用于修饰人和物，表示所属关系。
三、关系副词的使用：1. wherewhere 引导的定语从句用于修饰地点，表示具体的位置。
2. whenwhen 引导的定语从句用于修饰时间，表示具体的时间点或时间段。
3. whywhy 引导的定语从句用于修饰原因，表示具体的原因或理由。
四、定语从句的省略：在定语从句中，如果主语或宾语和主句的主语或宾语一致，或者关系代词在从句中作宾语，都可以将关系代词省略。
五、定语从句的位置：定语从句可以位于先行词之后或之前，如果位于先行词之后，则先行词和定语从句之间需要有逗号分隔。
六、关系代词和关系副词的区别：关系代词在从句中担任成分，而关系副词只起连接作用。
例如：The house where I live is very beautiful.（关系副词 where 连接整个从句）七、定语从句的用法：1. 修饰人或物定语从句可以用来修饰人或物，对关系从句中的名词进行补充说明。
定语从句考点大观
A
C
7、定语从句与其他从句的区别 （1）定语从句与地点状语从句的区别是看有无表示地点的名词作先行词，有则是定语从句，试比较： You should leave the toy where you can find. I still remember the bus stop where / at which I met you. （2）定语从句与结果状语从句的区别是看从句的连接词是否在从句中作成分，作成分的是定语从句；若连接词在句中不作成分时，则为结果状语从句。试比较 He is such a kind person as everybody likes. He is such a kind person that everybody likes him.
6、定语从句与强调结构的区别 （1）It was in this house ______ he was born. （2）It was this house ______ he was born. （3）It was in the house ________ he used to live in that the exhibition was held. A. where B. that C. which D. there 判断是否是强调结构的方法是去掉it is /was …that, 若整个句子结构和意义不受影响，则为强调结构，否则为定语从句。
as引导非限制性定语从句常见结构有
众所周知
如前所述
正如已经指出的
正如我们所看到的
正如所盼望的/ 希望的/料想的
情况常常如此
5、which 引导非限制定语从句，指代整个主句的内容，从句只能置于句尾。 The decision was right, which was exactly what he wanted. 6、which 引导非限制性定语从句，指代主句中的一个词（先行词）从句置于先行词后，可在句中或句尾。 The football match, which I watched yesterday, is very interesting. 7、which 引导非限制性定语从句，指代整个主句的内容，从句的谓语带有宾语，有的还带宾语补足语。 That things improved, which astonished me. 8、which 引导非限制性定语从句，指代整个主句的内容从句为否定式或带否定前缀的形容词。 He was married again, which was unexpected.

定语从句考点第二节考点分类解析【考点一：关系词的省略问题】这是一个比较基础的考点，也是所有学生必须掌握的一点。
有些题目会在这个地方考查学生的细心程度。
如：He is not the man(that)he was.(先行词在从句中作表语)The man(whom/who/that)I spoke to is my sister.(先行词在从句中作宾语)The book(which/that)I borrowed yesterday is very interesting.(先行词在从句中作宾语) This is the very book(that)I have been looking for.(先行词在从句中作介词的宾语)道理其实很简单，那就是：只有先行词在限定性定语从句中作宾语或表语时，关系词才能被省略。
非限定性定语从句的关系词无论如何也不能省略。
先行词在从句中作主语或状语时也不能省略关系词。
如：（2006年北京卷）Women_______drink more than two cups of coffee a day have a greater chance of having heart disease than those________don’t.A.who;不填B.不填;whoC.who;whoD.不填;不填解析：本题含有两个定语从句。
先行词分别是women和those。
它们在从句中很明显都是作主语的（因为，后面动词都没有主语）。
所以，关系词均不能省略。
答案：C。
这里还有一个例外：that可作关系副词，往往省略，先行词多为way,day,morning,time等。
如：I don’t like the way(that=in which)he talks.This is the third time(that)he has been late this week.Then came the day(that)he had to leave.I stayed at home on the days(that)I am not busy.不过这个知识点属于比较偏的那一类。
高考题和各地的模拟题中鲜有涉及。
【考点二：关系代词that的特权】不可否认的是，关系代词that在定语从句中仿佛享受某种特权。
至少在许多同学们心中是这样的。
我们就来盘点以下它的特权：一、行使特权的条件：1、限定性定于从句；2、先行词是物。
二、具体来说，即在满足上面两条的基础上，以下几种情况，关系代词一般选择that，而不选which。
★This is the best book（that）I have ever read.先行词是最高级或被最高级修饰。
★The first book that I bought is about how to learn English.先行词是序数词或被序数词修饰。
★I did all（that）I could do at that time.（还有much,little,something,everything,nothing, anything,none等代词）先行词是上述代词。
★The only thing（that）he can do is to say sorry to her.（先行词前的修饰词还可以是any,few, little,no,all,none of,the very等）先行词有上述词修饰。
★Do you know the things and persons（that）they are talking about?先行词既有人又有物。
★Which is the book that you like?★Who is the woman that was praised at the meeting?主句已有疑问词who/which时。
当然，这是刻板的语法，口语中可能会有所突破。
【考点三：关系代词that的禁区】有两种情况下，关系代词不会用that,而用which。
一、非限定性定于从句；二、介词提前时。
如：The student was late for class7times a week,which made her teacher mad.The factory makes two millions batteries a year,most of which are sold abroad.【考点四：关系代词as的使用】最近几年，关系代词as的使用越来越受到出题人的青睐。
其实，这个考点非常容易,有以下四种情况，关系代词一般用as。
一、当先行词中有so,such等修饰语时；如：This is so good a book as I can hardly tear myself away from.Never promise such things as you can’t achieve.很显然，语法做出这样的规定，主要是为了和so/such…that的结果状语从句相区别。
我们的主要任务就是判断从句是否是定语从句。
当然，金钥匙还是看从句中是否缺少成分。
如：This is so good a movie as we all wish to see.This is so good a movie that we all wish to see it.第一个句子中，最后的see没有宾语。
因此，它是定语从句，用as。
而第二个句子中，有宾语it，因此，它是结果状语从句，选that。
二、当定语从句置于句首时；如：As is known to all,the earth travels around the sun once every year.As we had expected,the students who had cheated in the exams were punished.定语从句一般放在先行词的后面，但这里是个特例，以上两个句子的先行词分别是逗号后面的句子。
这个考点上，考生最头疼的问题是如何分辨as引导的定语从句和it作形式主语的句子的问题。
如：It is known to all that the earth travels around the sun once every year.其实也不难。
从“脸谱”上看就不同，as引导的定语从句中间有逗号并且没有that.。
而it作形式主语的句子中间必须有that还一般没有逗号隔开。
三、当先行词中有the same修饰时，有时用that也有时用as来引导定语从句。
二者意思稍有不同。
如：This is the same shirt as I wore yesterday.(这件衬衣和我昨天穿的那件一样。
意思是说并不是同一件。
)This is the same shirt that I wore yesterday.(这是我昨天穿的那件衣服。
同一件衣服。
)看似怎么说都行。
但有些语境就只能用as。
如：The students in New York are using the same textbooks as we are using.四、定语从句有“像．．．那样”之意时；如：He won the big prize for a third time,as his coach had predicted.The man must be from Australia,as we can see from his accent.这时，as的用法和环境和which极为相似。
所以，一般的出题人会避免二者同时出现在同一题目的选项中。
一旦同时出现了，否定句一般只能用which，因为此时不能翻译成“像…那样”。
如：He won the big prize for a third time,which we hadn’t expected.【考点五：分析成分的能力和意识】在定语从句做题的过程中，重要的不是所谓的‘语感’，而是静下心来，认真地分析先行词在从句中作什么成分，因为，这才是关系词选择的最具决定性意义的因素。
有时，同学们更加愿意凭直觉做题，结果自然是对少错多。
分析成分的能力和意识就显得非常重要。
先有意识，再具有能力，才能百战不殆。
如：Mr.Goodman has to be away on business on Feb.8th,________happens to be his girlfriend’s birthday.A.whichB.whenC.thatD.on which解析：很多同学都会选择B项，因为Feb.8th是一个表示时间的概念。
但是，仔细看来，定语从句中的谓语动词happens to还没有主语。
也就是说，先行词在从句中作的是主语，而不是时间状语。
所以，答案：Ａ。
Last Sunday,we visited the Lincoln Memorial,________,of course,was crowded with visitors from all over the world.A.whichB.whereC.thatD.it解析：和上面的题目相似，这个题的主要迷惑点在于先行词the Lincoln Memorial是个表示地方的名词，所以总是会有人选where。
但是，在插入语of course后面的was还是没有主语。
因此，答案：Ａ。
【考点六：几个特殊的个例】一、有这么两个题目，在各种练习中出现的机会较多，同学们问得也不少。
1.Is this school_____you visited last Friday?答案：Ｄ。
A.thatB.whereC.whichD. the one2.Is this the school______you visited last Friday?答案：Ｂ。
A.whatB./C.whereD.in which这两个题看似相同，实则不然。
只需要变成陈述句就可以看出其中的“猫腻”。
1.This school is______I visited last Friday.2.This is the school______I visited last Friday.很明显，第一个句子还没有先行词，直接选择that或which都不成立，因为，定语从句如果没有自己修饰的对象，它存在的价值就没有了。
所以我们不得不先垫上一个代词the one来接受后面定语从句的修饰。
句子二比较简单，由于先行词在从句中作visit的宾语，关系词可以省略。
二、way作先行词的定语从句：１、I don’t like_____you speak to her.（1993）答案：Ａ。
