量词的使用：由于英语中名词分可数与不可数，量词的使用也有区别：修饰可数名词（a) few / fewer / fewest many / more / most a great （good) many many a a number of the number of既可修饰可数名词 也可修饰不可数名词a lot of / lots of plenty of （time， money， people)
修饰不可数名词（a) little / less / least much / more / most a great （good) deal of an amount of / amounts of the amount of量词使用中应注意的几个问题：1) 分清可数名词和不可数名词是前提；
2) 不要把量词的形式搞混淆了：下面哪个表达形式是对的？
A. A lot students have come back from the summer holiday. B. A few of the students have come back from the summer holiday. C. A great many of students have come back from the summer holiday. D. Many a student has have come back from the summer holiday. E. The number of students have come back from the summer holiday. F. A number of students have come back from the summer holiday.以上六个表达方式中只有F 是对的。为什么？
A. a lot students → a lot of students B. a few of the students → a few students C. a great many of students → a great many students D. Many a student has come back from the summer holiday. E. The number of 表示数目，如：The number of the students in our class is 50. A number of 表示"一些"，"不少"，认真对比一下，看出问题来了吗？
问多少钱、多少重量时用：How much…？问距离时用：How far is it from…to…？
