as后+一定加人称代词的宾格吗？

当然不是
It is just as you like.
事情就如你喜欢的那样。

四、在as或than后，若没带有动词时，多用宾格。如：

I am as tall as him. 我和他一样高。

I am taller than her. 我比他高。

当人称代词用作表语、用于than, as 之后或用于强调句中被强调时，可以用宾语：“Who is it?” “It’s me.” “是谁呀？”“是我。”He sings better than me. 他比我唱得好。He is as tall as her. 他和她一样高。It’s me who did it. It’s me who did it. 这是我干的。但是，若than, as 后的人称代词后跟有动词，则必须用主格：
He sings better than I do. / He is as tall as she is.

对

这样记就好了

语法知道的太复杂反而头晕

LZ记得在as后用宾格就好了
