定语从句的省略 关系代词充当从句宾语我们前面说到连接词在定语从句中充当一个成分,有可能是主语、有可能是宾语,我相 信大家肯定还记得,这里我们要告诉大家,当这些连接词充当的是宾语时,可以省略。例如 book(that/which) we bought last year nowvery popular. We can see boys(who/whom/that) quitehappy. 关系代词充当从句主语当关系代词充当从句主语时,也可以省略,但是省略后的从句要发生形式的变化,原从 句若为主动语态,后面的动词结构要变成分词ing 形式,原从句若为被动语态,后面的动词 结构直接为过去动词结构。这种结构在英语语法中称为分词作定语。例如 novelwhich professormainly discusses Chineseeconomy. novelgiven professormainly discusses Chineseeconomy. novelwhich mainly discusses Chineseeconomy novelmainly discussing Chineseeconomy professor.SP: why的先行词reason 或可用that 指代的名词也是定语从句的原因状语时,关 系代词或关系副词可以省略。例如 which/why)you dislike reason(why/for which) he changed his mind. 表示方式的先行词way,其后的关系代词可用that也可省略,例如 Everyone does hetalks. Do you know teachertreated his students.
