Q4:

Only seven people this century have been killed by the great white shark,  the man-eater of the movies—less than those killed by bee stings.

1. movies—less than those
2. movies—fewer than have been
3. movies, which is less than those
4. movies, a number lower than the people
5. movies, fewer than the ones

觉得这个ones出来得很诡异，我觉得应该用those来指代阿，因为是可数的所以应该用fewer,结果就是没有答案。能否介绍一下ones得用法？（以前看到说oneself只能用在指前面出现one 得时候。）Answer: e

不从ones的角度出发,从less, fewer排除..

另外,
1．that和those通常用作指使代词，也可用作替代词。它们总是伴随着限定性的后置修饰语，分别等于the one和 the ones

我一直记得可以互换..也请达人来看一下我的理解是否正确.

是E。 后面比较级修饰SEVEN。THE ONES 指代THE PEOPLE。

这里的THOSE用的怪怪的，感觉THOSE 后面应该有个WHO才对。继续讨论。。
