This is the best hotel that I know. that 既可以指人也可以指物,在从句中做主语或谓语动词的宾语,但不能直接放在介词后面做介词宾语。 注: which/that 在从句中作宾语时,可以省略,做主语不可省。 关系副词 作用 先行词 例句 whose 定语 物 The classroom whose window is open is 室。 when 状语 时间 I still remember the day when you leave for 一天。 where 状语 地点 This is the school where my mother works. 这就是我妈妈工作的学校。 2. 限定性定语从句是对先行词进行修饰、限制说明的,是句中不可缺少的组成部分,主句和从句之间不用逗号隔开。 . I have a brother who is a student. 非限定性定语从句是对主句先行词的补充说明。 没有从句不影响主句意思的完整,一般用逗号把主句和从句分开。 引导非限定性定语从句的关系代词有 who, whom, whose, which等。 这些关系代词都不能省略,通常不用关系代词 that。 . I have a brother, who is a student. I have lost a pen, which I like very much. 3. 在下面 几种情况中必须用 that 引导定语从句 先行词是不定代词 I need something that can help me finish the work.。
