as as 后接人称代词的主格还是宾格

Question

He is as tall as me.还是He is as tall as I.

Answer 1

因为as是个连词，所以as连接的两个词是并列成分，所以as后面的词的格式和与它并列的词的格式相同。因为He is as tall as ```中as后面的词语He并列，He是主格，所以as后面的词也是主格，所以是He is as tall as I.只要是连词，连接的词就是并列成分，他们的格式就相同。但是如果是介词，介词后面的词都是宾格形式,如in和like。

Answer 2

宾格与主格都是可以的，具体情况看语境。比如说：
This dictionary is not as/so useful as you think.这本字典不如你想象的那样有用。
Your pen writes as smoothly as mine.你的钢笔书写起来和我的一样流畅。
She cooks as well as her mother does.她烧菜烧得跟她母亲一样好。
Danny is not so wise as he is witty．丹尼为人风趣，但欠明智。
You’ve made just as many mistakes as I have．我和你犯的错误一样多。

Answer 3

应该用：as I.
