定语从句讲解（包含各种特殊情况对比，题目都是易错题） 1）定语从句的基本概念：定语从句是用来修饰名词或代词的从句，起形容词作用，也称为形容词性从句。被定语从句修饰的词叫先行词，定语从句一般紧跟先行词。定语从句一般用关系代词或关系副词引导，关系词在定语从句中充当一个成分，并在含义上替代先行词。 The man is my cousin. He came to see me this morning. 替换：The man who came to see me this morning is my cousin. 先行词 关系代词在定语中做主语，不可省略 ↖定语从句 2）关系词: ①关系代词（指人/指物/表所有格）; A.指人的关系代词： who,做主语或宾语； whom，只做宾语； that,做主语或宾语（但指代人称并充当从句主语时，通常用who） He is a student. We should learn from him. 替换：He is a student (who, whom, that) we should learn from. 关系代词充当从句主语时，不能省略，充当宾语时，可以省略。 B.指物的关系代词： which,做主语或宾语； that,做主要或宾语； He sent me a present last night. The present is a mice watch. 替换：The present (which, that) he sent me last night is a nice watch. 关系代词充当从句主语时，不能省略，充当宾语时，可以省略。 C.表所有格的关系代替： 指某人的或某物的：whose,做先行词的所有格 Is there anyone? Her name is Linda. 替换：Is there anyone whose name is Linda? ②关系副词（时间/地点/原因）。 A. where指地点，充当地点状语 This is the place. We spent our childhood in that place. 替换：This is the place (which / that) we spend our childhood
