问题 The new method for refining metals was______that they became practical for many purposes, one of which was for making pans.

选项 A、so more cheaper
B、so much cheaper
C、so many cheaper
D、such much cheaper

答案 B

解析本题考查形容词的比较级，习惯上可用于修饰比较级的副词主要有much，far，even，still等，以加强比较级的含义，表示"更……"的意思，所以A、C、D可以排除；题意为，提炼金属的新方法变得如此便宜以至于它们被用于许多实用的目的，其中之一就是用于做平底锅。
