1、Unit4SharingPeriodIIIGrammar定语从句一、【学习目标】1、复习和掌握定语从句中关系代词和关系副词的作用和功能，能准确选择定语从句所需的关系代词或关系副词。2、较好地掌握定语从句的用法，理解定语从句，运用知识点解题。二、【合作探究】一、走近定语从句定语从句：在复合句中修饰名词或代词的从句叫定语从句定语从句是由关系代词或关系副词引导的从句，其作用是作定语修饰主句的某个名词性成分，相当于形容词，一般紧跟在它所修饰的先行词后面。先行词:被定语从句修饰的名词、代词称为先行词关系词：引导定语从句的关联词称为关系词，关系词有关系代词

2、和关系副词。关系代词有that,which,who,whom,whose,as等，关系副词有where,when,why等。关系词常有3个作用:①_______________作用，引导定语从句。②代替主句中的________，甚至可能是主句中的一部分或者整个主句。③在定语从句中充当一个_____________________。二、走进定语从句1、限制性定语从句：种类先行词关联词例句说明定   （人）在从句中做主语或宾语（物）who (whom) Thisisthedoctorwhosavedtheboy’slife.Sheisthenews

6、修饰时定从用that引导。先行词被theonly,thevery,thesame等修饰时用that. 句WhoisthemanthatistalkingwithTom?Whichofthebooks(that)youboughtiseasytoread?当主句以who、which开头的特殊疑问句时，定从要用that人或物的whoseTheprofessorwhosedaughterteachesyouEnglishisDr.Williams=Theprofessor,thedaughterofwhomteachesyouEnglishisDr.
