a quantity of后同样可接不可数名词或可数名词的复数形式。但当它作主语时谓语动词一般根据其所修饰的名词而定，而quantities of作主语时，不论其后的名词可数或不可数，谓语动词都用复数。
7 1．(2009年福建卷)—Why does the lake smell terrible?
—Because large quantities of water________.
A．have polluted B．is being polluted
C．has been polluted D．have been polluted
【解析】 句意为：——这湖水怎么这么难闻？——因为大量的水已经被污染了。本题考查时态、语态及主谓一致问题。water与pollute为被动关系，故排除A项；B表“正被污染”，故排除；large quantities of后加名词，谓语动词应与quantities保持一致，故排除C项，答案为D项。
