问题 If additional deposits of oil are found, it will expand the amount that can be used as fuel and reduce the price of oil, even if the deposits are not immediately tapped.

选项 A、it will expand the amount that can be used as fuel and reduce the price of oil
B、the amount that is able to be used as fuel will expand and the price of oil be reduced
C、it will cause and increase in the amount that is able to be used as fuel and a reduction in the price of oil
D、the amount that can be used as fuel will increase and the price of oil will drop
E、it will increase the amount of oil that can be used as fuel and cause a drop in the price

答案 D

解析本题解题的关键同上题一样，在于it的指代。由于it will是该句主句，且it并非形式主语，那么it的指代对象只在it之前，即在if从句中，if从句中唯一的单数名词是oil，若it指oil，我们把oil带进A、C、E，3个it作主语的选项中，就会发现读起来逻辑不通，要么是“油会降低油的价格”，要么是“油会增加油的量”，均不能令人信服，因此判断it指代有误，A、C、E错；B、D用the amount取代it，解决了指代不清的问题。但B有3个错误：(1)谓语动词用expand，表“扩张，膨胀”，和the amount属搭配不当；(2)be reduced暗示了一种人为的力量，而本句价格下降是源于“市场的力量”(潜在的供应量增加)，而非人为的力量，用被动语态不恰当。(3)在前面曾提过：can的使用优先于be able to，既然D用了can，就应优先考虑D。D中：用increase代替了B中的expand，will drop取代了be reduced，解决了B中的所有缺陷，因而D对。
