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。

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.

2、不定代词的功能与用法

除 every 和 no外不定代词既可用作名词，也可用作形容词。every和 no在句中只能作定语。

all 都，指三者以上。

all 的主谓一致：all 的单复数由它所修饰或指代的名词的单复数决定。

all 通常不与可数名词单数连用，但 all 可与表时间的可数名词单数连用。

all 还可以与一些特殊的单数名词连用，如 all China， all my life， all the way

2、 both 都，指两者。

both 与复数动词连用，但 both… and…可与单数名词连用。

4、neither 两者都不

neither 作主语时，谓语动词用单数。

作定语与单数名词连用，但 neither… nor 用作并列连词，可与复数名词连用。其谓语采用就近原则。

可用于下列句型，避免重复。 She can't sing，neither (can) he.

5、 不定代词 one和 you都可以用来表示“无论谁，人人”的意思，但是以个是第三人称，一个是第二人称，故在指代同一个人的时候不能又用 one，又用 you。同样，也不可以用 all 和you。

6、 each, every 的用法。

each 可用作代词，后面可以不跟名词，every是形容词，后面必须跟名词;each 和 every作形容词使用时，后面的名词虽然有 and 连接，为复数概念，谓语动词仍须用单数。
