请问a quantity of与 quantities of修饰的名词作主语时,谓语动词单复数如何决定?请举例说明,

乖,一般没有a quantity of这样表达.你要么用a large/small quantity of或者the quantity of~
好了,说重点,看仔细了~
a large/small quantity of + 复数名词 + 谓语动词复数
a large/small quantity of + 不可数名词 + 谓语动词单数
quantities of + 复数名词、不可数名词 + 谓语动词复数
the quantity of + 复数名词、不可数名词 + 谓语动词单数
造句就算了,我要去吃饭liao~
