问题描述：
The students in our class study harder than ( ) in their class.
A.ones B.those c.these d.them
然后告诉一下为什么
答
B
those =the students (in their class)
(them代替的就是The students in our class,排除。相对于我们班的学生来说，他们班的学生不用these来修饰。onces是泛指，而后面有in their class，说明是特指 ，所以应该是the ones.)
答
b因为是那个班的学生
答
选 those
those与前面的students 相呼应,是复数代词
