Question

a great many of的用法是什么？

Answer 1

一、用法
a great many 后直接接复数名词,动词用复数.用于肯定句中,相当于many,a large number of.
a great many后接可数名词复数,不加of.
如：I have a great many things to do.
如a great many后接代词时,则须加上of.例
如:A great many of them have seen the film.

二、区别
★ 修饰可数名词的有：a good / great many, a large / great number of, scores of等，谓语动词用复数形式。如：
A great / good many words and expressions have come into the language from American English.
这门语言吸收了美国英语中的许多单词和短语。
There were scores of boxes, all waiting to be checked and loaded. 大批的箱子等着检验后装运。

★ 修饰不可数名词的有：a large amount of等，谓语动词用单数形式。如：
He has spent a large amount of money on his new house.
他在新房子上花费了许多钱。

★ 既能修饰可数名词，又能修饰不可数名词的有：a lot of, lots of, plenty of等，谓语动词根据被修饰的名词是可数还是不可数来决定单复数形式。如：
There are a lot of / lots of people in that room.
那个房间里有许多人。
There’s a lot of / lots of rice in the bag.
那只口袋里有许多大米。
There are plenty of eggs in the fridge.
冰箱里有足够的鸡蛋。
Don’t worry about it. We have plenty of time.
不要着急，我们有充裕的时间。
