Lucy has been working ________ since she got ________ A in the French test.

问题描述:

Lucy has been working ________ since she got ________ A in the French test.
A. more harder; a B. much harder; an
C. as harder; the D. more hardly; another
为什么是has been working不是应该用过去分词吗

句意是 在法语考试得到A 之后,Lucy学习得更加勤奋了.所以选Bhas been working 这里有过去分词been,这是过去完成进行时态,be + ing表进行时比较级harder只能用much或者a little修饰,不能用more hard本身就可以做努力...
