(二)副词
1. 副词通常在句中作状语,修饰动词,形容词,副词,或整个句子。

(三)形容词与副词的比较级:
1) 同级比较
1“as十形容词或副词的原级十as”
形容词与副词的同级比较,其肯定式要用“as十形容词或副词的原级十as”;而否定形式要用“not asso)形容词或副词的原级十as,” 用于表示两个人或事物之间的差别。句子中两个as作用不同,前一个as是副词,含如此的意思;后一个as是连词,表示如同的意义。

He didn’t do so much preparation for the exam as I did.
John doesn’t work so hard as Henry
2) 当同级比较的形容词是same时,前面一般不用as,而要用the, “the same as
He said the same at the meeting as he had promised me.
3) 使用原级比较应注意的问题
当同级比较的形容词跟单数名词连用时,要注意不定冠词的位置: as +形容词+a+单数可数名词+ as
Exercising is as good a way as any to lose unwanted weight.
同级比较前也常用状语justalmosttwicethree times等修饰。状语应放在第一个asso之前。
Last year, Matt earned twice as much as his brother, who has a better position.
同级比较结构后面那个 as是个连接词,后面应接省略了某些成分的状语从句。

We’ll give you as much help as we can(give you).

2) 比较级句型
