副词及其基本用法
副词主要用来修饰动词，形容词，副词或其它结构。
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.
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
