问题补充：
Though the player is over forty, he can run some younger players.
A. much fast than
B. more faster than
C. so fast as
D. as fast as
答案：
A. much fast than
B. more faster than
C. so fast as
(答案→)D. as fast as
解析：句意:虽然这名球员已经四十多岁了，但是他还能跑得喝一些年轻的球员一样快。as…as 和…一样，表示同级比较，两个as 之间用形容词的原级。当用于否定句的时候，第一个as 可以用so；much 可以修饰形容词的比较级，但不修饰原级，故A不对；B选项形式不对，fast 的比较级是faster。故选D。
