定语从句中关系词可以省略的几种情况：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。如： I have taken with me the tw bks (that/ which) yu asked me t return t the City Library.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。
如：The way (that/ in which) yu lk at the prblem is wrng.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。如： The reasn (why/that) he wanted t sell his huse was that he needed a lt f mney fr his peratin.
介词+关系代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which或whm。先行词指物时，用which；先行词指人时用whm。在这个结构中，介词的确定的原则是：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. 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.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.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. 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.
Cmplete the sentences with f whm, t whm, fr which r in which.
The regin ________ the antelpes live is very cld.The vlunteer _________ I spke said cnditins were difficult. Jiesang is a her _______ we shuld be prud.There are several animals _________ special laws have been intrduced.

限制性定语从句和主句之间不用逗号分开，修饰主句中的某一个名词或名词词组或代词；非限制性定语从句常用逗号和主句隔开，可以修饰主句中的某一个词，也可修饰整个句子。非限制性定语从句不能用that引导，引导非限制性定语从句的关系词不能省略。
