问题描述：
Mary doesn't work_____her brother
A;as hard as B;as hardly as C;as harder as D;so hardly as
答
A
as...as之间用形容词或副词的原型，所以排除C
hard是勤奋的意思，hardly是几乎不的意思，没有勤奋的意思。
所以选A
答
hard本身有副词勤奋地的意思，hardly是副词，意思是几乎不，跟hard毫无关系，排除bd，as+形容词+as，表示什么跟什么一样的怎样，不需要比较级，排除c。
答
选A 如果有 so hard as 也可
首先要区分hard和hardly的意思
hard作副词，意思是 努力，努力地
hardly意思为 几乎不，含有否定的意思
工作努力应该用work hard
并且 as...as中间应该使用形容词或副词的 原级
答
A
work hard 努力工作 hard adv. 努力地, 辛苦地
hardly adv.
刚刚, 几乎不
答
A;as hard as ;
as+形容词/副词的【原级】+as,hard本身就可以作为副词,不需要用hardly.
