as ______ as possible 中是填careful 还是carefully？为什么？解答一下好吗？

填carefully~因为修饰的是do our homework这一个短语，所以用副词carefully.

看情况而定。如果作表语，那么就用careful，
如果修饰动作，就用carefully.
例：
You should be as careful as possible.
He needs to write this article as carefully as possible.

得看你前面的词是什么词了。
动词的话就用Carefully
系动词之类用careful
这里的词性和没有as..as possible是一样的
EG：
Speak as carefully as possible.--因为是Speak carefully.
You should be as careful as possible.--因为be careful.

as...as possible中间填形容词还是副词都是可以的.
填careful 还是carefully,都是可能的，关键看在句子里上下文.
如:
You should be as careful as possible. 这里be后面必须跟形容词careful.
Clean the bottle as carefully as possible. 这里clean sth.carefully,do后面显然应该跟副词.

要看你修饰的是什么词，是动词用carefully，是名词用careful。
例如：he talks as carefully as possible.talk是动词所以用carefully
题目答案：carefully，do是动词

carefully，因为是为了修饰前面的do啊~~~~
