Aristotle concluded that heavy objects always fell faster than light ____. A. them B. ones C. these D. those
答案为 B。但是,我不明白为什么不可以选 D。ones 和 those 不是都可以用作替代词,来代替前面的复数吗?
ones 与 those 用作替代词时有一个本质上的区别: 前者代替含零冠词(无冠词)的复数名词(表达谈话双方不能共同确认具体所指的人或物), 后者代替带有定冠词的名词(表达谈话双方共同确认具体所指的人或物)。在上面的句子里, light objects 是不带定冠词的名词短语, 故不能用 those 来代替, 而必须使用 ones。
另外，从语法特点上看，those 不能接受前置修饰，而只能接受后置修饰。因此，light (red, blue) those 的搭配是错误的。而 ones 既可接受前置修饰又可接受后置修饰，故 light ones 是正确的。
[附注] the ones 与 those 有时是可以互换的, 见 those/the ones。请做下面的英语试题:
