1.同级比较as (so)...as结构：
在表示“和……一样……”时，也可用as(so)... as(前面的as和so后要用原级)。肯定句(或疑问句)中都用as...as结构(a)，否定句中用as...as或so...as都可以(b)：
a. He could speak English as fluently as an Englishman.
他英语说得和英国人一样流利。
She loved him as much as her own child.
她爱他像爱她自己孩子一样深。
We must arrange everything as well as we can.
我们要把一切尽量安排好。
b. I can't run so (as) fast as Betty.
我跑得没有贝蒂快。
I didn't do my work as (so) well as I should.
我的工作没干得我应干的那么好。
She didn't sing as (so) well as she usually does.
她唱得没平常那样好。
这种结构中也可用一个表示程度的状语：
I don't speak English half so well as you do.
我的英文讲得不及你一半好。
“I can run ten times as fast as you.”said the hare.
野兔说，“我可以跑得比你快十倍。”
2.副词最高级的用法：
在用副词最高级时，多跟一短语说明比较的范围：
Of all his novels，I like this one best.
在他所有小说中我最喜炊这一本。
Among the three girls, she works the hardest.
三个姑娘中她最用功。
Who can throw it farthest?
谁能把它扔得最远?
Let's see who sings best.
咱们看谁唱得最好。
副词最高级前定冠词可以省略，大部分情况都不用定冠词。
