as+形容词或副词的原级＋as.什么叫副词的原级啊?再多举一点as as的词语,

副词的原级、比较级和*
副词和形容词一样，也分原级、比较级和*。副词的比较级和*的形式变化分两种：规则变化和不规则变化。
1）规则变化形式：一般说来单音节的副词多采用加-er和-est 的形式，多音节的副词多采用加more和most的形式。
注：以-ly结尾的副词通常都以more和most分别表示比较级和*（early一词例外，因为其后的-ly不是词尾，比较级earlier，*是earlist）。
2）不规则变化形式
形容词与副词比较级和*的基本用法
一、原级比较的基本用法
1. 原级比较由“as＋形容词或副词(或再加名词或短语)＋as ”构成“原级相同”比较句，表示两者比较；其否定式，即“程度不及”比较句型为“not so(as) ＋形容词或副词＋as”，而且as…as结构前可用just, almost, nearly, quite等表示程度的词修饰

〔A〕 to run for fifteen minutes

〔C〕 you run for fifteen minutes
〔D〕 fifteen?minute walking

3) Alaska is twice 〔A〕 as larger 〔B〕 as 〔C〕 the next largest 〔D〕 state， Texas.
2. “as (so)＋名词＋as＋名词”进行名词比较，这时一般情况下有一个表示原级的比较词，但如果第一名词前出现了形容词修饰该词或出现副词修饰谓语，应当用so而不用as

〔B〕 so

二、比较级
1. 比较级由“形容词(副词)比较级＋than＋…，”构成表示在两者中间一方比另一方“更加…”。连词than后可接句子，也可接名词、代词、名词短语、介词短语、动词、动词不定式、?ING结构和?ED结构，有时也可省去than。
6) Natural mica(云母) of 〔A〕 a superior 〔B〕 quality is cheapest 〔C〕 to obtain than synthetic 〔D〕 mica.

三、*
1. *用于三者以上比较，形容词的结构形式是“定冠词＋形容词*＋名词＋表示范围的短语或从句”(如all, of all, of the tree, in the world, that has ever taken place等)
12) The more 〔A〕 fearsome of all the 〔B〕 animals in 〔C〕 the Western 〔D〕 Hemisphere is the grizzly bear.

as...as的用法
as...as意为"和……一样"，表示同级的比较。使用时要注意第一个as为副词，第二个as为连词。其基本结构为：as+ adj./ adv. +as。例如：
(1)This film is as interesting as that one.这部电影和那部电影一样有趣。
(2)Your pen writes as smoothly as mine.你的钢笔书写起来和我的一样流畅。
其否定式为not as/so +adj./ adv. +as。例如：
This dictionary is not as/so useful as you think.这本字典不如你想象的那样有用。
若有修饰成分，如twice, three times, half, a quarter等，则须置于第一个as之前。例如：
Your bag is twice as expensive as mine.你的袋子比我的贵一倍。
几个关于as...as的常见句型：
(1)as...as possible
Please answer my question as soon as possible.请尽快回答我的问题。
(2)as...as usual/before
She looks as pretty as before.她看起来和以前一样漂亮。

(4)as far as

一些带有as...as结构的常见短语归纳：

as deep as a well像井一样深
as light as a feather像羽毛一样轻
as soft as butter像黄油一样软
