1)副词修饰动词、形容词或其他副词,表示动作、状态的特征或某种性质的程度。根据其用途与含义,副词可分为下列六大类:

(1)时间副词。常用的有:ago,before,now,then,soon,already,yet等。

(2)地点副词。常用的有:here,there,up,down,above,below,inside,outside等。

(3)疑问副词。常见的有:where,when,why,how等。

(4)程度副词。常见的有:very,much,so,too,quite,enough等。

(5)方式副词。多由“形容词+ly”后缀构成。如:carefully,quickly,easily,quietly等。

(6)频度副词。常用的有:always,often,sometimes,usually,hardly,never等。

2)副词在句中主要用作状语。也可充当定语、表语等。如:

It’s snowing heavily outside.(状语,修饰动词)

I have never heard such a beautiful voice.(状语,修饰动词)

unluckily, he failed in this physics exam again.(状语,修饰整个句子)

He was too excited to say a word.(状语,修饰形容词)

Class is over.(表语)

The weather here is different from that of Singapore.(定语)

3)程度副词通常位于被修饰的形容词副词之前,但enough则要放在后面。如:

It was much more freezing today than yesterday.

He ran so fast that I couldn’t catch up with him.

We got up early enough to catch the first bus.

4)频度副词通常位于行为动词之前,be动词、助动词和情态动词之后,但一般不放在句末。如:

I have never been late for class.

You must always work like that.

5)几个副词同时出现时,其顺序一般为:方式副词+地点副词+时间副词(也可位于句首)。
