c
后面的动词和quantity 配合
有很大争议的关于"a quantity of" 和"quantities of"的主谓一致的问题,关于 a quantity of /quantities of + n.+谓语 中的谓语的单复数形式说法有三：
A.a quantity of /quantities of + n.+谓语,其中谓语的单复数形式与quantity的单复数形式保持一致,eg:
Quantities of nuts were on the table.
A quantity of nuts was on the table.
B.对于a quantity of + n.+谓语 中的谓语的单复数形式与a lot of 相同,即遵循意义一致原则；
而对于quantities of + n.+谓语 中的谓语一定用复数形式,eg:
There is only a small quantity of wine left.
A large quantity of air conditions have been sold since the summer came.
Huge quantities of oil were shipped to Japan last year.
C.a quantity of /quantities of + n.+谓语 中的谓语的单复数形式与a lot of/lots of 相同,即遵循意义一致原则.eg:
Great quantities of sand was washed down the hillside by the rain last night.
各个老师争论个不停..总的来说就是和quantity单复配合吧

选C，Large quantities of 后面可以加任何名词，但是后面的动词一律用复数形式。A large quantity of 后面加不可数名词，所以动词用单数。

C
可修饰可数或不可数名词，谓语动词单复数取决于quantity，即quantity用单，quantities用复

C 谓语动词看 quantity是单数还是复数 是单数的话谓语动词就用单三 是复数的话谓语动词用复数形式

quantity是单数 后面谓语动词就用单数
quantity是复数(也就是quantities) 后面谓语动词就用复数

选C
quantities of和a large quantity of都可修饰可数和不可数。但是不同的是，后面谓语动词的形式要看quantity的形式，而不看它所修饰的名词。
所以不看cotton 和bamboo就知道了

基本解释

adj.大量,一些
例句
Quantity of order
订单数量
Quantity of output
出产量，输出量；供给量
Quantity of sale
销售量
Quantity of shipment
货运量；发运量

C
看quantity得单复数决定谓语动词的单复数

a large quantity of n. 谓语动词 用单数
