问题补充:
Every year money and energy is spent on environment protection.
A. large quantities of
B. a large number of
C. a large quantity of
D. a plenty of
答案:
A. large quantities of
B. a large number of
(答案→)C. a large quantity of
D. a plenty of
解析:考查词组辨析:这几个词都有“许多,大量”的意思,A和C项修饰可数或不可数名词,谓语的单复数和quantity的数保持一致,B项修饰可数名词, D项应该是plenty of修饰可数或不可数名词,这句话修饰money and energy,所以排除B和D,因为be动词用的是is,所以用a large quantity of,句意:每年大量的钱和精力都花在了环境保护上了。选C。
