a great number of修饰可数还是不可数

a great number of修饰可数名词，后面接复数名词，意为：许多的。相当于a great many, a lot of或lots of。

a great number of，of后面直接加复数可数名词。，相当于a great many, a lot of或lots of。

A great number of people agreed with him. 许多人都同意了他的看法。

There are a great number of books in our school library.我们学校的图书馆有很多书籍。

a great number of和a great deal of 在意思上相同。但用法不一样，a great number of后面只能跟可数名词的复数形式，而a great deal of 后面只能跟不可数名词。

若用a great number of ，后面仍需用名词复数，但谓语动词则应用单数。因为这时表示的是数字，而非数量。
