Grammar1.什么是定语从句？2.什么是先行词?关系代词？如何确定？3.如何把两个句子合并为定语从句？定语从句一、概念

定语从句

在句中做定语，修饰一个名词或代词，被修饰的名词词组或代词即先行词。定语从句通常出现在先行词之后，由关系词（关系代词或关系副词）引出

。关系代词有：who,whom,whose,that,which等。关系副词有：when,where,why等。二、用法

1、关系代词引导的定语从句

关系代词所代替的先行词是人或物的名词或代词，并在句中充当主语、宾语、定语等成分。关系代词在定语从句中作主语时，从句谓语动词的人称和数要和先行词保持一致。先行词：是被定语从句所修饰的词（通常是名词或代词）

关系词的作用：1.引导定语从句2.在从句中替代先行词，在定语从句中充当一定的成分，通常是主语或宾语，作宾语时常可以省略。定语从句：先行词+关系词(that/which/who)+从句修饰a)他就是我昨天见到的那个人。①Heistheman.②Isawhimyesterday.HeisthemanwhomIsawyesterday.b)你认识站在那边的那个人吗？①Doyouknowtheman?②Heisstandingoverthere.Doyouknowthemanwhoisstandingoverthere?（）
