什么是副词

副词(adverb)修饰动词、形容词和其他副词等,说明时间、地点、程度、方式等概念。如:often往往,here这里,very很,quickly很快地。
副词的构成
1)本身就是副词,如now现在,there那里,rather颇。
2)由形容词加词尾-1y变来,如firmly坚决地,happi1y幸福地。
3)与形容词同形
early adj. 早的 early adv. 早
high adj. 高的 high adv. 高高地
long adj. 长的,长久的long adv. 长久地
副词的种类
副词可分为下列几种:
1)普通副词(ordinary adverb)如:together一起,well好,seriously认真地,slowly慢,carefully小心地。
2)疑问副词(interrogative adverb)如:when何时,where何地,how如何,why为何。
3)关系副词(relative adverb)如:where,when。
4)连接副词(conjunctive adverb)如:then然后,so所以,there{ore所以,however然而,hence所以,thus这样,nevertheless然而,otherwise否则,still可是,仍然。
副词的用法
副词在句中可用作:
1)状语(这是副词在句子中的主要功用)
It is raining hard.雨下得很大。(副词hard作状语,修饰动词is raining。)
Don't drive too fast.车子不要开得太快。(fast是副词,作状语,修饰动词drive,副词too又修饰副词fast。)

副词的位置
1)修饰动词时,有三种位置。
2)修饰形容词和副词时,须放在被修饰词之前。如:
It is a rather difficult job,这是一件颇为困难的工作。(rather修饰形容词difficult)

副词的比较等级
和形容词同形的副词的形式变化与形容词完全相同。但以词尾-1y结尾的副词(注意early一词的-1y不是副词的词尾)须用more和most。另外,须注意下面例词中well,badly的不规则变化。如:
原级比较级 最高级
hard 努力地harderhardest
fast 快faster fastest
well 好better best
badly 坏 worseworst
early 早 earlier earliest
quickly 快 more quicklymost quickly
happily 快乐地 more happily most happily
