We all thought that Betty could have run if she had worn the sports-shoes that day.

A. even faster

B. more slower

C. much quickly

D. still fastest

答案：

(答案→)A. even faster

B. more slower

C. much quickly

D. still fastest

解析：考查比较级的修饰词。Even可以修饰比较级，表示“更加”;More后面直接加多音节的形容词或者副词；much修饰比较级的形式；still也要修饰比较级的形式；从选项来看，A项正确。BCD都不符合语法。故A正确。句意：我们都认为Betty本可以跑得更快，如果那天她穿了那双运动鞋。故A正确。
