quantity作主语时谓语用单数还是复数

1. 若单独用quantity作主语,谓语动词用单数。如:

It is used to emphasize that the quantity is very large. 它用于强调数量很大。

2. 若用于a great (large, small) quantity of…结构,其后主要接不可数名词,但有时也接复数名词;这类结构用作主语时,其谓语的数原则上与其中的名词的数保持一致。如:

There are a small quantity of apples in the house. 房子里有少量的苹果。

A large quantity of food was on the table. 大量的食物摆在桌上。

3. 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(与其中名词的数无关)。如:

Huge quantities of oil were spilling into the sea. 大量的石油渗到海里。

Large quantities of rice have been destroyed in the flood. 大量的庄稼在洪水中被毁坏了。
