Answer 1

副词及其基本用法
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.
改错：(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.
此外从分类上来看：
1、 时间和频度副词:
now,then,often,always,usually,early,today, lately, next,last,already,generally,frequently, seldom,ever,never,yet,soon,too, immediately, hardly,finally,shortly, before, ago,sometimes, yesterday.

4、 程度副词（放在被修饰词之前）
much,little, very,rather,so,too,still, quite, perfectly, enough, extremely, entirely,almost, slightly.
5、 疑问副词（一般放在句首）

6、关系副词,（一般放在句首）
