——What do you think of the concert?
——I really enjoy it. I didn't expect it was ____ wonderful.
A. as B. more C. most D. very
这题为什么选A ，为什么不能选B, 不是否定词+比较级表示 最高级的概念吗？
I can't be better today. 我今天感觉再好不过了。

Answer 1

楼主要注意答句中存在着主从复合句，且主句时态为一般过去时。
按照楼主的理解，选B的话则句意不通顺：我（当初）预计它再好不过了？或：我（当初）没有预料它会（比现在我感觉的要）更好？

答案选A，此时从句存在省略，即：
I didn't expect it was as wonderful.
= I didn't expect it was as wonderful (as it is).
我当初没有预计到它和现在（我感觉的）那般好。

Answer 2

as 这里是与自己之前的想象或预料的进行对比

Answer 3

这里的 not as 表示的是比想象当中要好。
