Question

Tom has made great progress.He did a lot_____ (bad)last time

Answer 1

Tom has made great progress.He did a lot__worse___ (bad)last time
译：汤姆已经取得了极大的进步，他上次做的要糟糕的多。

A lot在这里相当于much，后面如果接形容词或者副词，只能是比较级，表示...的多。所以，bad得变成比较级worse.

满意的话，记得采纳咯~

Answer 2

worse (a lot 后接比较级，突出程度）

Answer 3

填worse 用bad的比较级：Tom这次做得比上次好多了。
