2023-12-11 17:05:07文/张哲a quantity of+可数名词复数、谓语动词用复数;a quantity of+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。
a quantity of谓语用单数还是复数
a quantity of+可数名词复数、谓语动词用复数;a quantity of+不可数名词、谓语动词用单数。
若单独用quantity作主语,谓语动词用单数。

它用于强调数量很大。若该结构变成(large)quantities of…这样的形式,则当它用作主语时,其谓语动词一律用复数。
如:Huge quantities of oil were spilling into the sea。大量的石油渗到海里。
