作文中怎么写which引导的定语从句【一】
基本概念定语：用于修饰名词或代词的成分就叫定语。 定语从句：如果修饰某个名词或代词的定语是一个完整的句子，这个句子就叫定语从句。定语从句所修饰的名词或代词叫先行词。定语从句放在先行词后面。定语从句的引导：定语从句的引导词代替的是先行词。
1、当定语从句所修饰的名词是事、物时，用that/which引导，且that/which在定语从句中作主语或宾语。e.g:a.Thisisthepenthat/whichIboughtyesterday.
2.当定语从句所修饰的名词是人时用that/who引导，引导词再从句中做主语或宾语。
3.定语从句修饰的'名词时地点时用which/that或where引导:若地点名词在定语从句中是作主语或宾语就用that/which引导，是作地点状语则用where引导，可与“介词+which”互换。作visited的宾语作介词in的宾语作work的地点状语
4.当定语从句修饰的名词是时间名词时：若在定语从句中作主语或宾语用that/which,作时间状语则用when,同样可与“介词+which”互换。
5.当定语从句所修饰的名词在定语从句中表示原因时用why。’tcomeisstillamystery.
6.当定语从句修饰的名词和引导词后面的那个词之间是所有关系时，用whose引导。女儿已经出国的那个人是位医生
