3、re,语法精析,担任定语功能的句子称为定语从句,定语从句所修饰的词叫先行词。连接先行词与从句的词叫关系词。定语从句一般由关系代词和关系副词来引导,关系词不仅在先行词与定语从句之间起连接作用,而且在从句中充当一定的成分。根据关系词与先行词的密切程度,定语从句可分为限制性定语从句与非限制性定语从句。,限制性定语从句与先行词关系密切,从句是整个句子不可缺少的部分,从句与主句之间不用逗号隔开。如果去掉它,句子意思就不完整或不明确。译成汉语时,一般先译定语从句,再译先行词。引导限制性定语从句的关系词有:who,whom,that,which,as,whose,when,where,why。其位置一般紧跟
