在句子中作定语，修饰名词或代词的从句。这种从句由关系代词或关系副词引导，并作句子成分。 定语从句还叫做嵌入句，因形容词定语，所以又称之为形容词性从句。
定语从句的位置：通常在先行词（在主句中）后。
wh(主语、宾语)，whm(宾语)，that(主语、宾语), whse(定语)
that(主语、宾语),which(主语、宾语)whse(定语)
where (地点状语)
when (时间状语)
1. 先行词: 被定语从句修饰的词叫先行词。2. 关系词: 引导定语从句的词叫关系词。3. 关系词通常有下列三个作用: (1)引导定语从句; (2)代替先行词; (3)在定语从句中担当一个成分。4. 关系代词在从句中作主语、宾语、定语或表语; 关系副词在从句中作状语。
关系代词和关系副词的区别　　定语从句中关系代词和关系副词的判断方法:
若是及物动词, 后面若无宾语, 用关系代词; 若是不及物动词, 则用关系副词
把关系词放进定语从句中, 若作主语或宾语用关系代词; 若作状语用关系副词
　　当关系代词在定语从句中作介词的宾语时, 我们通常用“介词+关系代词”引导定语从句。关系代词只能用————————先行词指物时, 用————————先行词指人时, 用——————————在这个结构中, 介词的确定的原则是:
(1)依据定语从句中动词或形容词等所需要的某种习惯搭配来确定。He is the man n whm yu can rely. 他是你可以信赖的人。Jack intrduced t me his friend with whm I was nt very familiar. 杰克向我介绍了我不很熟悉的那个朋友。
(2)依据与先行词搭配的具体意义而定。I’ll never frget the day n which we wrked tgether in the cuntryside. 我不会忘记我们一起在乡下工作的日子。
(3)根据所表达的意思来确定。The clever by made a hle in the wall, thrugh which we culd see what was happening inside the huse. 这个聪明的孩子在墙上挖了一个洞, 透过它我们可以看到屋里发生的事情。
(4)表示“所有”关系或“整体中的一部分”时, 通常用介词f。Julie was gd at German, French and Russian, all f which she spke fluently. 茱莉亚擅长德语、法语和俄语, 这三样她都说得流利。
【温馨提示】　　在定语从句中, 有一些含介词的动词短语不可拆开使用, 如lk after, lk fr等。The babies whm the nurses are lking after are very healthy. (正确)The babies after whm the nurses are lking are very healthy. (错误)
(1)“代词+ f + which/whm”引导非限制性定语从句　　这个结构中, 代词常常为all, each, ne, many, much, mst, sme, nne, bth等, “代词+ f + which/whm” 通常在定语从句中______________, 说明整体中的一部分。有时候也可把“f+which/whm”置于代词前。
It is reprted that tw schls, bth f _________are being built in my hmetwn, will pen next year. 据报道, 在我的家乡两所学校都正在建设中, 将于明年投入使用。
(2)“数词+ f + which/whm”引导定语从句　　这种结构常用来引导非限制性定语从句, 有时候也可以把“f + which/whm”置于数词前。数词包括百分数和基数词。(3)“the+名词+ f which/whm”引导非限制性定语从句　　这个结构中, f which/whm充当定语, 修饰前面的名词, 整个结构相当于“whse+名词”引导的定语从句。
(4)“the+形容词比较级(最高级)+ f + which/whm”引导非限制性定语从句There are tw buildings, the larger f __________stands nearly a hundred feet height. 这儿有两座建筑物, 较大的那座几乎有100英尺高。
关系词可以省略的几种情况(1)定语从句的先行词在定语从句中作宾语时, 关系词通常省略。I have taken with me the tw bks (that/which) yu asked me t return t the City Library. 我把你要我送还给市图书馆的那两本书带走了。
(2)先行词是way, reasn, time, place等且它们在定语从句中分别作方式、原因、时间和地点状语时, 其后定语从句的相应关系词that/in which, why/that, when, where等可以省略。The way (that/in which) yu lk at the prblem is wrng. 你看待问题的方式是错误的。
(3)由and, but, r等并列连词连接两个或两个以上的定语从句修饰同一个先行词时, 第一个关系词可以省略, 但第二、三个一般不可以省略The reasn (why/that) he wanted t sell his huse was that he needed a lt f mney fr his peratin. 他想卖掉房子的原因是他的手术需要很多钱。
