1、定语从句难点突破微课教案定语从句难点突破微课教学附件 教学设计 基础知识梳理 定语从句: 在复合句中, 修饰某一名词或代词的 从句叫定语从句. 先行词:被定语从句所修饰的名词或代词叫做先行词 关系词:引导定语从句的词叫关系词 引导定语从句的关系词 指代人 指代物 所属关系 指地点 指时间 指原因 定语从句重难点精讲 重难点一:如何判定用关系代词还是用关系副词 1.找出定语从句中是否主语和宾语都齐全。如齐全用关系副词。用什么关系副词看先行词。 I will never forget the days when I stayed with you. 2、如定语从句中缺主语,用关系代词。 如定语从句
2、中缺宾语,确定定语从句的 谓语动词是不是及物动词,如果是, 则用关系代词,如果不是,则用关系副词。 1)This is the house which/that dates back to Qing Dynasty. 2)Yesterday we went to visit the house where the great writer used to live. 3、如定语从句中谓语结构是被动结构/或系表结构,有主语,则用关系副词。 1)KunMing is a beautiful place where flowers are seen all the year round. 重难点二:
3、that和which的选择 (1) 指物时在下列情况引导词只用that,不用which。 当先行词为all, much, little, few, none, something, anything, everything, nothing等不定代词时,如: All that can be done has been done. 先行词被all, every, no, some, any, little, much修饰时: Ive read all the books (that) you gave me. 先行词被序数词或形容词最高级修饰时。 This is the best book (t
4、hat) Ive ever read. 先行词被the only, the very, the last 修饰时。 That flower is the only one that I really like. 当先行词既指人又指物时 He talked about the teachers and schools that he had visited. 主句是疑问词who, which, what 引导的特殊疑问句时,定语从句只能用that 引导 Who is the person that is standing at the gate? 当关系代词在从句中作表语时: China is no longer the country that it used to be. 关系代词指物时只用which不用that的两种情况 1、非限制性定语从句,即逗号后 2、介词后, 另外which 不仅可以指代前面先行词,还可以指代前面整句话内容。 教学反思 基础差的学生对如何正确选用关系代词和关系副词仍然有困难,如何让这部分学生牚握好定语从句。 专家点评 录屏时内容多,讲解偏少。
