答案A
因为系动词is 后接形容词,而B 修饰实义动词
加油!不明白再问!那网上怎么说as...as中间可以加副词又可以加形容词？？？没错，但这里的动词是系动词is ，故后接的是形容词区别：Lily doesn't doher homework as carefully as Peter .Lily dosn't do her homework as careful as Peter,,对吗不对，因为careful 是形容词，不能修饰动词do ，一定要用 carefully哦，我们都是N01中学的学生，，英语怎么说呢？？ 下次再评论里说了。。我没财富没法追问了Oh, we are all students from No. 1 Middle school .你的追问也够三次，请采纳后再问！
