Question

how many和how much的用法区别是什么？

Answer 1

how many 和 how much 是询问数量的两个常用疑问词,但用法有一定区别:
1. how many 用于问论数目,后接可数名词,如:How many books do you have? 你有多少本书?
How many students are there in the class? 班级有多少学生?
2. how much 用于问量,金额或者不可数名词,如:How much money do you have? 你有多少钱?
How much water did you drink? 你喝了多少水?
How much time do you need? 你需要多少时间?
3. 当名词既可数又可量时,根据问句中的名词是表示可数概念还是总量概念来决定使用how many 还是how much。如:How many papers did you bring? 你带了多少份文件?(可数)
How much paper is used? 用了多少纸?(不可数)
4. 如果不确定名词是可数还是不可数,通常使用how much也没问题,所以当有疑问时以how much为主是个简单实用的原则。总结如下:•How many + 可数名词,询问数目
•How much + 不可数名词或表示总量的名词,询问数量、份量
•名词既可数又可量时,根据语境确定使用how many 或how much
•有疑问时通常都可以使用how much希望这个解释能帮助您理解how many 和 how much的用法区别。
