方卓越的回答：

as……as是同级比较的含义。一般是这样的固定格式：

 

as 形容词/副词 as 被比较的句子。

 

这个句子可以衍生出许许多多不同种类的比较句子结构，如：

You should run as quickly as you can 你应该尽力跑。

又如：

He was asked to get to school as early as possible 他被要求尽可能早到学校。

 

【请注意：如果存在名词的情况，可以做如下处理】

1) as （冠词）形容词+名词 as ……

2）（冠词）名词+ as 形容词 as……（后置定语）

 

如：

I have as many books as you (<=> I have books as many as yours).

同样地，

I have as a beautiful vase as you (<=> I have a vase as beautiful as yours).
