1、 2019人教版必修一unit5 Discovering Useful Structures 定语从句学案（另附50道定语从句单句语法填空题）（注：定语从句PPT课件请参见我们制作的必修一第四单元Discovering Useful Structures 定语从句）一、 定语从句的定义定语：用来修饰名词代词的形容词等。主要是形容词。从句：从句是相对于主句而言的。从句一定有连接词引导。I was late for class, because my clock didnt go off.定语从句：用来修饰一个名词或者代词的句子叫做定语从句。也叫形容词性从句。PS:定语从句可以翻译出一个“的”字。
2、二、 定语从句的结构主句：含有被修饰的名词+从句：引导词+修饰名词的句子This is a book that I bought online.主句中被修饰的名词叫做先行词，连接主句和从句的连词叫做关系词。三、 定语从句的功能定语从句用来修饰限定一个名词或者代词。主要是限定所指人或事物的范围。强调哪个（种）人，哪个（种）物。I have a book.我有一本书（泛指）I have a book （ that I bought online ）.我有一本网上买的书。（指明这本书是网上买的，而不是其他地方来的。言外之意他还有一些其他地方来的书。）四、 定语从句的分类和区别He has a sis
