1、初中英语定语从句知识总结一、概念定语从句就是从句充当定语成分，换言之，用句子修饰限定名词。一般我们用形容词修饰名词。例如：I like brilliant students.我喜欢聪明的学生。可以改写为定语从句：I like students who are brilliant.在表达复杂的意思的时候，形容词表达力度不够，从句便成为必要。I like students who study hard.我喜欢努力学习的学生。I like students who never give up.我喜欢从不放弃的学生。二、结构定语从句=先行词+关系词+从句作为从句，当然有对应的主句。先行词先行词就是被定
2、语从句修饰限定的成分，可能是一个名词，也可能是短语和句子。先行词是主句里的成分，主语或宾语。名词I like students who are brilliant.先行词是名词，主句的宾语。代词He who laughs last laughs best.笑到最后的才是赢家。先行词是代词，主句的主语。短语He likes climbing mountains, which makes him strong.他喜欢爬山，这种运动让他很强壮。先行词是短语，主句的宾语。句子I was very patient towards my daughter，which my wife seldom was.

5、ay when I met you for the first time.我永远不会忘记你我初见的那天。先行词是地点，用where，This is the place where the war broke out.这是战争爆发的地方。并不是先行词是时间地点就一定用when和where。如果指代的时间地点是从句的主语或宾语，还是要用that或whichThis is the place I told you about many times before.这就是我过去多次和你说起的地方。先行词表原因，用why，This is the reason why you failed.这就是你失败的原
