From this material we can ______hundreds of useful products.
A.derive
B.reduce
C.employ
D.replace
A.derive
B.reduce
C.employ
D.replace
【选择】A. derive
【解析】
注意,句中的置于句首的介词短语 from this material 应该是说明所选谓语动词的来源.四个选项中只有A 和 B 两项 reduce 可以与 from 这种说明来源的状语搭配,所以 C 和 D两项可以排除.
derive from 指“通过…得到”,reduce from 指“从...中减少”.从题意来看,本句意思是“我们可以通过这种原料获取数百种有用产品”,因此 B 项也不在选择之列.
