请问高手们一个英文观念问题
(就算不是高手也欢迎参与讨论)
我之前学的文法(好像是赖世雄老师的文法书)
文法说：
as much as要接主格
或
as much as要接主格+动词
例如：
You earn as much as I.
(你赚得跟我一样多)
=You earn as much as I do.
但是我看牛津高阶英汉双解第八版第98页

它写
He doesn't earn as much as me.
后来我去google
其中一个网页
https://goo.gl/ZYQKno
有些母语人士说只有老文法人士跟非母语人士会坚持这样说
如果他们所言不假
是不是as ..... as.....的第二个as后面都可以接受格？？
例如：
就英文能力而言，他跟我一样好
In terms of English command, he is as good as I.
=
In terms of English command, he is as good as I am.
=
In terms of English command, he is as good as me.
我这样的延伸对吗？？
各位台湾的英文学习者
会不会怕写出as ....as+受格
结果老师老骨头给你扣分？？
请问大家怎么看
谢谢大家！！！

现在老师不知还考 than me 还是than I? 以前 than me一定错。

我的情况是，因为说和写是操之在己，我会用一定正确的写法和说法，就上面的例子，我会用主格。但就读和听，看或听到受格也不会意外，我能懂就好。
