修饰可数名词和不可数名词的词首先要搞清楚，是修饰可数名词或不可数名词,而不是单数或复数名词.可数名词都有复数形式，而不可数名词没有复数形式。a large deal of， plenty of 和 a good supply of 在多数情况下修饰不可数名词，如： plenty of water， a great deal of time，不过它们也可以修饰可数名词，如 plenty of men。a quantity of 在多数情况下修饰可数名词,如 a quantity of boxes， 不过也可修饰不可数名词,如 a quantity of milk。quantities of 与上述的一样一、只能修饰可数名词的词语有： many, many a(n)， a good / great many， a （great / large) number of, scores of， dozens of 等。例如： Scores of people went there in the first few days after its opening。 开张后的头几天，很多人去了那儿。I have been there dozens of times. 我已去过那儿很多次了。There're a number of students reading English in the classroom. 教室里有许多学生在读英语.Many a student has（=many students have）visited the Great Wall.（谓语动词用单数） 很多学生都游览过长城。In winter， a good many animals sleep under the snow. 冬天很多动物在雪下冬眠。注意: 注:a good [great] many 后直接跟名词，不用介词 of。但是，若其后所接名词有 the， these， my 等限定词修饰,则要用介词 of 表示“…中的很多”：例如： a great many of my friends 我的朋友当中的许多人。A great many（of the） graduates have found jobs. 毕业生中很多人已经找到了工作。二、只能修饰不可数名词的词语有： this， that， little, a little, a bit of， much， a great deal of， a great / large amount of 等。有些名词形式上是复数，但却被用作不可数名词,使用 much, little 等修饰语例如: Is there much water in the bucket？ 桶里有很多水吗？ He always has a great amount of work to do. 他总是有很多工作要做。He hasn’t got much brains. 他没什么头脑.He took much pains to do the work. 他费了不少心做这工作。I said I wouldn't want much wages. 我说过我不要很多工资。It’s high time you were taught ...
