Unit 7 How much are these pants？Period4 Revision of unit7一、 问题探究与拓展活动How much和how many的用法区别：how much与how many的意思基本相同，但前者用来修饰不可数名词，也可单独使-用，意思是“多少钱”；后者用来修饰可数名词复数。如：How much are the pants?这裤子多少钱? How much is the book?这本书多少钱?How much bread d0 you want?你要多少面包? How much meat is there on the table?桌子上有多少肉?How many apples d0 you want?你要多少苹果? How many students are there in your class?你们班有多少学生?练习设计用how much和how many完成下列表格。 Ask Answerl. _ _ is the red sweater?Its $302. _ _ are the pants?Theyre $503. _ _is the T-shirt?_ $304.
