While a huge amount of money ___been spent stopping pollution , large quantities of water_ _still heavily polluted．
A．have; is
B．has ;are
C．have; are
D．has ;has
答案
答案：B
考察主谓一致，a huge amount of money是不可数名词，故后面用单数第三人称形式。large quantities of water大量的水，这里的谓语动词要和前面的quantity一致,quantity是单数 后面谓语动词就用单数 quantity是复数(也就是quantities) 后面谓语动词就用复数。故选B。
