限制性定语从句修饰先行词，对先行词起修饰作用，不同引导词有不同的含义和用法，
下面，就来给大家分享一下选择定语从句的引导词的技巧，一起来看看吧！
*限制性定语从句
限制性定语从句修饰先行词，对先行词起修饰作用，紧接先行词之后，无逗号，若省
去，原句意思不完整。引导定语从句的关系代词有who, whom, whose, which, that等。who, whom, whose用于指人，whose有时也可指物，相当于of which；which用于指物；that既可指人也可指物，但
只用于限制性定语从句中。关系代词除了引导定语从句，替代先行词外，还在从句中担
任主语、宾语、定语等。
*非限制性定语从句
非限制性定语从句既可修饰先行词，也可修饰整个主句，起补充说明作用，与主句之间
有逗号隔开，若省去，原句意思不受影响。不可用that引导非限制性定语从句。关系词
不可省略。
定语从句的引导词有关系代词who， whom，whose，which，that， as；关系副词
when， where，why。定语从句中引导词的选用主要看先行词在定语从句中作什么成
分或者是定语从句中缺什么成分。
1．定语从句中缺主语，修饰人时用who /that，修饰物时用which /that引导。如：Is this the factory which /that makes TV sets？The man who /that visited our school is from Australia．
2．从句中缺宾语，修饰人时用 who /whom /that或省略引导词；修饰物时用
which /that或省略引导词。如：
Gone are the days which /that we spent together in the village．He is the man who /whom /that I think to be worthy of our praise．3．从句中缺时间状语，用when或介词＋which引导。如：The day finally came when /on which I was given a job．We"ll put off the outing until next week，when we won"t be so busy．4．从句中缺地点状语，用where或介词＋which引导。如：Please put the letter on the desk where /on which he can easily find it．
5．从句中缺原因状语或先行词是 reason时，引导词用why /for which / that。
如：
This is the reason why /for which / that he didn"t come to the meeting．6．从句中缺定语，人和物都用 whose引导。如：A child whose parents are dead is called an orphan．Please pass me the dictionary whose cover is black．7．当先行词是way时，其定语从句的引导词用in which /that。如：The way in which /that he looks at problems is wrong．
