Jack is a careless boy. He doesn't write as ______as Mary. A careful B more carefully CcarefullyD more careful请问more 在这里是出题意图

续约…↗承诺你好，我认为应该选c 因为as...as中间用原级，又因为修饰write用副词，所以选c要用more应该说he writes more carelessly than Mary.

carefully C

C
as carefully as 和..一样认真
more的出现无非是混淆视听
它想表达：Jack 比 Mary 更认真
但是我们看原句,Jack is a careless boy,后面Mary的出现肯定是起对比作用（Mary 更认真）
那么那个空肯定就不能填 as more carefully as Mary 了（他没有比Mary认真,也不能说明他比Mary不认真.）
还是要根据语境分析

C
