急!谁能告诉我plenty of，a lot of ，lots of，much，many的区别?

much修饰不可数名词
many修饰可数名词
plenty of 能修饰可数名词和不可数名词
a lot 是副词短语,修饰动词 如 I like it a lot.
a lot of =lots of用来修饰名词 如 I have a lot of books.
例如：1、There is plenty of time.
2、There are plenty of eggs in the basket.

plenty of一般加不可书名词:比如plenty of time
a lot of =lots of(当然细微区别也是有的)用于肯定,修饰可数不可数都可以
而much只修饰不可数名词或形容词副词.一般用于否定
many修饰可数名词,也用于否定

但口语中many,much也可以用在肯定句中

much不可数
many可数
