(课件网) 1/24 定语从句 2/24 思维拓展 知识梳理 疑难点拨 3/24 知识梳理 1. 功能:在句中作定语,相当于形容词,修饰名词或代词。 2. 位置:放在被修饰名词之后。 3. 先行词:定语从句所修饰的名词为先行词。 (1)先行词一般是名词和不定代词,如:some?, any?, every?和no与?body, ?thing的合成词;或all,none,any,some,that,those等代词。数词也可以作先行词,人称代词也同样可作先行词。 (2)先行词与关系词是对等关系。必须注意两点: ①先行词在从句中作主语时,从句谓语动词的数由先行词决定。 He is the person who was praised by captain yesterday. ②关系词在从句句子中充当了成分,其意思就是先行词的意义,所以在从句中不能重复其意。 They are the persons who the captain praised yesterday. 4. 关系词:引导定语从句的词都叫关系词。 关系代词:who, whom, which, that, whose, as。 关系副词:when, where, why。That 偶尔也作关系副词。 4/24 疑难点拨 一、关系词的确定 1. 在定语从句中,当先行词指物时,下列情况的关系词宜用that而不用which。 (1)先行词被形容词最高级,序数词,数词几种词修饰或被 only,any,few,little,no,all,one of等修饰时。 (2)先行词为all,much,little,none,few,one,something,anything等不定代词时。 (3)先行词中既有人又有物时。 He often recalls the persons and things that he experienced in university.
