This computer is ___ than that one ,but it works much ____.A:expensive;fast B:the cheapest ;trying helpingC: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

C:more expensive;faster 两者之间的比较用比较级 不用最高级 最高级用于三者及以上

选C
根据前后意思应该是这台电脑比那台更贵,却比那台电脑更有效率
A中expensive前面应加more因为后面有than比较级
而B前后意思不符合
D中因为是than,所以用比较级而不是最高级,还有much用来修饰比较级,后面不能加the
因此,选C
