问题描述:

This computer is ___ than that one ,but it works much ____.
A:expensive;fast B:the cheapest ;trying helping
C:more expensive;faster D:the most expensive;the faster
选什么?其他3个为什么不选?

选C
第一个空格 因为是than 所以要用比较急 如果是the est 或者the most 的话 就没有than that one 了
第二个空格 因为fast 这里是副词(fast既可以作形容词也可以作副词),如果要用the faster 的话 那应该是 but it is the faster one 就可以
