as在这两句话中的意思原句I don't think I'd be as careful with my schoolw

1.I don't think I'd be as careful with my schoolwork without it.
这个句子中的as是“同样地”的意思,在此是副词,修饰动词原形.
2.I might also not care as much about my education.
这个句子中的as与第一句中的as是同样的用法.当 as后面修饰形容词或副词时,as就只能是一个副词,原 意就是“同样地”,且只能修饰原级.它没有“能”的 意思.

I don't think I'd be as careful with my schoolwork without it.
我不认为我不用它而[能]认真做我的作业
as是能的意思
I might also not care as much about my education.
[很]
我可能关于我的叫苏也[很]不够仔细

I don't think I'd be as careful with my schoolwork without it.
here "as" can be replaced by "so"; but "so" is always used like this "not so ";(那么的意思)

I might also not care as much about my education.
(it has the same meaning with the "as" in first sentence)
