While a huge amount of money ___been spent stopping pollution , large quantities of water_    _still heavily polluted．
A．have; isB．has ;areC．have; areD．has ;has
B
考察主謂一致，a huge amount of money是不可數(shù)名詞，故后面用單數(shù)第三人稱形式。large quantities of water大量的水，這里的謂語動詞要和前面的quantity一致,quantity是單數(shù) 后面謂語動詞就用單數(shù) quantity是復數(shù)(也就是quantities)  后面謂語動詞就用復數(shù)。故選B。
