副词主要用来修饰动词，形容词，副词或其他结构。

　　一、副词的位置：

　　1) 在动词之前。

　　2) 在be动词、助动词之后。

　　3) 多个助动词时，副词一般放在第一个助动词后。

　　注意：

　　a. 大多数方式副词位于句尾，但宾语过长，副词可以提前，以使句子平衡。

　　We could see very clearly a strange light ahead of us.

　　b. 方式副词well，badly糟、坏，hard等只放在句尾。

　　He speaks English well.

　　二、副词的排列顺序：

　　1) 时间，地点副词，小单位的在前，大单位在后。

　　2) 方式副词，短的在前，长的在后，并用and或but等连词连接。

　　Please write slowly and carefully.

　　3) 多个不同副词排列：程度+地点+方式+时间副词。

　　注意：副词very 可以修饰形容词，但不能修饰动词。

　　(错)　I very like English.

　　(对)　I like English very much.

　　注意：副词enough要放在形容词的后面，形容词enough放在名词前后都可。

　　I don´t know him well enough.

　　There is enough food for everyone to eat.

　　There is food enough for everyone to eat.

7 形容词与副词的比较级

　　大多数形容词(性质形容词)和副词有比较级和最高级的变化，即原级、比较级和最高级，用来表示事物的等级差别。原级即形容词的原形，比较级和最高级有规则变化和不规则变化两种。

　　1) 规则变化

　　单音节词和少数双音节词，加词尾-er，-est来构成比较级和最高级。

　　8 as + 形容词或副词原级 + as

　　1)在否定句或疑问句中可用so… as。

　　He cannot run so/as fast as you.

　　2)当as… as 中间有名词时采用以下格式。

　　as +形容词+ a +单数名词

　　as + many/much +名词

　　This is as good an example as the other is.

　　I can carry as much paper as you can

　　3)用表示倍数的词或其他程度副词做修饰语时，放在as的前面。

　　Your room is the same size as mine.

　　4) 倍数+ as + adj. + as　<=> 倍数+ that + of
