a large quantity of 和large quantities of的用法区别?
就是他们后面跟的名词与谓语动词应该用什么形态?希望能举例说明!
▼优质解答
答案和解析
quantities of无论修饰可数还是不可数名词、谓语动词都用复数.
例如:
Quantities of food (nuts) were on the table.桌子上有许多食品(坚果).
a quantity of+可数名词复数、谓语动词用复数;+不可数名词、谓语动词用单数.即修饰可数或不可数名词均可,作主语时采取就近一致的原则,其谓语动词通常与短语中of后面的名词的数保持一致.
例如:
A large quantity of beer was sold out.大量的啤酒被售出.
A large quantity of blouses were on sale.大量罩衫有售.
