复合句中起定语作用，修饰名词、代词、整个主句或主句中的一部分的从句。类型:限制性定语从句（描述主句所涉及的人或物的具体情况，是主句不可缺少的一部分；如省去，主句意义不完整或失去意义）。关系代词：that,which,who,whom,whose等。引导定

语从句的关系代词有三个作用：1）连接作用：引导从句，把从句和它所修饰的内容连接起来；2）替代作用：在从句中替代被从句所修饰的先行词；3）在从句中充当成分：作主语、宾语、表语、定语。指人指物主语宾语thatwhichwhowhom√√√√√√√√√√√√××

××关系代词在从句中可以：何时可以省略？做宾语时可以省略关系代词的用法与辨析(1)关系代词that与which在定语从句中,关系代词that既可指人，也可指物，which一般用于指物。在指物时，二者一般可以互换。★通常使

用that引导定语从句的情况：①当先行词为all,everything,anything,nothing,much,little,none等不定代词或先行词被theonly,few,little,no,a

ll,every,thevery等词修饰时。②当先行词同时包括人和物时。如：Theytalkedabouttheteachersandschoolsthattheyhadvisited.③当先行词前有序

数词first,last,next等或形容词的最高级修饰时。如：ThisisthefirstarticlethatI’vewritteninJapanese.④当主句是由who或which开头的疑问句时。如：Whoist

hemanthatisstandingbyJack?(2)关系代词who与whomwho指人，是主格，在定语从句中作主语，一般可用that替换。whom指人，是宾格，在定语从句中作宾语。在口语和非正式文体中可用who或that替换，也可以省略。(3)关系代词whosewhose
