谁决定引导词的用法？o I will never forget the day when I met you.因为从句不缺主谓宾，that在定语从句中扮演代词的成分，代词只能作主或宾语，when为副词，所以不可以二o I will never forget the day that we spent.缺宾语所以填that思考以下句子中的引导词为什么这么用？o You had better have some reason why you are left.o You had better have some reason that sounds perfect.1.看先行词，确定范围（3选1）.引导词在从句中能够充当的成分优点：缩小选择范围缺点：依旧得不到正确答案定语从句引导词的分类新标准引导词还可以按照引导词本身的词性分类，一共把引导词分成三类：L代词（在从句中一定要充当主语或宾语的成分）：who, whom, that, which.副词（在从句中不能充当任何主干成分）:where, when, why2.形容词（在从句中修饰离它最近的那个名词）：whose练习①夜莺用生命换来的玫瑰被扔掉了。
定语从句一．几个基本概念1.定语从句的定义：用作定语的从句叫定语从句。
2.先行词：被定语从句所修饰的名词或代词。
3.定语从句的位置：紧跟先行词（名词或代词）之后。
4.引导词：引导定语从句的词（包括关系代词和关系副词）。
﹙1﹚关系代词：that/who/whom/which/as﹙2﹚关系副词：when/where/why5.引导词的位置：位于定语从句之前（先行词之后）。
【as除外】6.引导词的功能（作用）：﹙1﹚连接先行词和定语从句。
﹙2﹚在定语从句中充当一定的成分（关系代词充当主语或宾语，关系副词充当状语）。
7.定语从句的类型：﹙1﹚限定性定语从句（主句和定语从句之间无逗号）。
①直接由引导词引导定语从句The man who you’re talking to is my friend.②由介词+关系代词（whom/which）引导The man to whom you’re talking is my friend.I need a pen with which I can write a letter.=I need a piece of paper on which I can write a letter.介词的选用可根据从句中的相关词组确定，该介词通常可以放在关系代词之前，也可放在从句之尾。
例如：The man (who/whom/that) I talked about at the meeting is from Beijing University.=The man about whom I talked at the meeting is from Beijing University.The palace (which/that) I often pay a visit to was built in the 17th century.=The palace to which I often pay a visit was built in the 17th century.﹙2﹚非限定性定语从句（主句和定语从句之间用逗号隔开）。
高中英语定语从句精讲定语从句是高中阶段的重难点,大家要学会下面的语法规则,并且需要通过以后的练习来逐渐透彻掌握。
学习中肯定会遇到一些困难,不好弄懂的知识点一定要结合例句细心多看几遍。
一、定语从句基本概念在复合句中,修饰名词或代词的从句叫定语从句。
引导定语从句的词叫关系词。
被修饰的名词或代词叫先行词。
定语从句一般放在先行词的后面。
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,as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。
1.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。
例如:Any man that/who has a sense of duty won’t do such a thing.任何有责任感的人都不会做这样的事。
2.非限制性定语从句主句与从句之间有逗号分开,起补充说明作用,如省去,意思仍完整。
例如: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.注意:非限定性定语从句中不能使用关系代词that。
四、关系代词的用法1.thatthat既可以用于指人,也可以用于指物。
在定语从句中作主语、宾语或表语,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。
(that作主语The coat(thatI put on the desk is blue.我放在桌子上的那件外套是蓝色的。
(that作宾语2.whichwhich用于指物,在句中作主语、宾语或表语,作宾语可省略。

The watch which you gave me keeps good time.✧ 3. They rushed over to help the man whose car had broken down.✧ 4. Beijing is not the city that it used to be.✧ 5.

This is the reason why the computer cannot entirely replace man.✧9.

高中英语定语从句精讲(一定义及相关术语1.定语从句:修饰某一名词或代词的从句叫定语从句。
定语从句一般紧跟在它所修饰的先行词之后。
2.先行词:被定语从句修饰的词叫先行词。
3.关系词:引导定语从句的词叫关系词。
关系词有关系代词和关系副词。
关系代词有that,which, who,whom,whose,as等;关系副词有when,where,why等。
关系词通常有下列三个作用:A、引导定语从句;B、代替先行词;C、在定语从句中担当一个成分。
例如:The man who is shaking hands with my father is a p oliceman.该句中,who is shaking hands with my father是定语从句,修饰先行词the man,“who”是引导定语从句的关系词,代替先行词the man,在定语从句中作主语。
(二关系代词引导的定语从句1.who指人,在定语从句中作主语。
The boys who are playing football are from Class On e.正在踢足球的男孩是一班的。
Those who want to go to the museum must be at the school gate at 7 tomorrow morning.想去博物馆的人必须在明晨7点到大门口集合。

定语从句讲解一、详细的定语从句讲解定语从句是由关系代词和关系副词引导的从句，其作用是作定语修饰主句的某个成分，定语从句分为限定性和非限定性从句两种。
状语从句分为时间状语从句，结果状语从句，让步状语从句，原因状语从句，条件状语从句以及行为方式状语从句。
名词从句包括主语从句，宾语从句，表语从句和同位语从句及there be句型。
一、限定性定语从句1. that即可代表事物也可代表人，which代表事物；它们在从句中作主语或宾语，that在从句中作宾语时常可省略关系词，which在从句中作宾语则不能省略。
而且，如果which在从句中作“不及物动词＋介词”的介词的宾语，注意介词不要丢掉，而且介词总是放在关系代词which的前边，但有的则放在它原来的位置2. which作宾语时，根据先行词与定语从句之间的语义关系，先行词与which之间的介词不能丢3. 代表物时多用which，但在带有下列词的句子中用that而不用which，这些词包括all, anything, much等，这时的that常被省略4. who和whom引导的从句用来修饰人，分别作从句中的主语和宾语，whom作宾语时，要注意它可以作动词的宾语也可以作介词的宾语5. where是关系副词，用来表示地点的定语从句6. when引导定语从句表示时间〔注〕值得一提的是，表示时间“time"一词的定语从句只用when引导，有时不用任何关系代词，当然也不用that引导By the time you arrive in London, we will have stayed there for two weeks.I still remember the first time I met her.Each time he goes to besiness trip, he brings a lot of living necessities, such as towers, soap, toothbrush etc.7. whose是关系代词，修饰名词作定语，相当于所修饰成分的前置所有格8. 当从句的逻辑主语是some, any, no, somebody, anybody, nobody, something, anything, everything或nothing时，常用there is来引导二、非限定性定语从句：非限定性定语从句的作用是对所修饰的成分作进一步说明，通常和主句间用逗号隔开，将从句拿掉后其他部分仍可成立1. which引导的非限定性定语从句来说明前面整个句子的情况或主句的某一部分2. 在引导限定性定语从句时，that有时相当于in which, at which, for which或at whichAttitudes towards daydreaming are changing in much the same way that(in which) attitudes towards night dreaming have changed. 人们对白日做梦的态度正在改变，这与人们对夜间做梦的看法的变化有非常相似之处。
高中英语语法讲解——定语从句(名师精讲必考语法知识点+实战训练，建议下载练习)一、先行词、关系代词和关系副词1．先行词(antecedent)就是被定语从句所修饰的名词。
在英语中，定语从句跟在被修饰词之后，所以被修饰词就是“先行”的词。
eg. The lovely girl often helps the old lady.She lives next door to our school.→The lovely girl who lives next door to our school often helps the old lady.→The lovely girl often helps the old lady who lives next door to our school.The lovely girl often helps the old lady.You met her at school yesterday.→The lovely girl (whom)you met at school yesterday often helps the old lady.→The lovely girl often helps the old lady (whom) you met at school yesterday.2．连接定语从句，要用关系代词(relative pronoun)和关系副词(relative adverb)。
关系代词和关系副词与连接词不完全相同，因为它们除了连接主句和定语从句，还在定语从句中代替一定的成分。
eg. The book which I bought yesterday is very interesting.← The book is very interesting. I bought the book yesterday.I have visited the house where Andersen wrote The Emperor’s New Clothes.←I have visited the house. Andersen wrote The Emperor’s New C lothes in the house.二、关系代词1．who的先行词是“人”，在从句中代替主语。
