题目

(A great many)people called to ask about her health这里为什么要填A great many
(A great many) people called to ask about her health这里为什么要填A great many
A great many不是后面接可数名词吗?这题为什么不能填A great many of呢
还有一个问题
How is this book different (from) that?
这里为什么要填from不能用of呢?

答案

a great many 跟a great many of 的区别
a great many后面直接加复数可数名词
a great many of 后面跟限定语再跟名词
例如:
a great many students
a great many of "my" classmates
be different from 是一个固定词组,与..不同
