a great many,a great deal,a great amount of,a large part of的区别
It is reported that _______ schools are improving their IT environment.
A.a great many B.a great deal C.a great amount of D.a large part of
请亲说说这4个选项的区别
请问 这里那些后面跟可数名词 哪些后面跟不可数名词？

答案

A
ABC都表示很多,A修饰可数（因为有many）,B修饰不可数（这个靠记）,这里不选b还因为后面没of（a great deal of sth.）,而c亦不可数（ a large amount of work, money, furniture,牛津解释）
D大部分（整体的一个部分）,不符合
如：a large part of my arm hurts我胳膊一大片都伤了
