1.副词比较级和最高级的构成规则有两种:两个和两个音节以上的副词都是在原级前加more和most,只有少数单音节词和个别双音节词在词尾加
-er和 -est,如:
fast faster fastest
early earlier earliest
brightly more brightly most brightly
有少数不规则形式,如:
well better best
badly worse worst
much more most
little less least
late later last
far farther/further farthest/furthest
2.副词有三个比较等级。
a.原级常用“as +原级+ as”结构,否定形式为“not as(so) … as”。在 as(so) … as 结构前可用just,
almost, half, nearly等词表示程度。 as从句后可省略可省的词。如:
He doesn't smoke half as (so) heavily
as his friends.
b.比较级常用“比较级+than”结构,否定形式用“not as(so) … as … ”或用“less … than
… ”结构。比较级前可用much, a little, a great(good) deal , any, no, even,
still, yet或者“数词+名词”构成的名词短语等来修饰。比较级也可单独使用。如:
I came three hours earlier than
others.
No sooner had he left the house
than it began to rain.
c.比较级“the more … the more”结构表示“越…就越”,“more and more … ”表示“越来越…”,如:
The harder you study now, the
better you will work in the future.
It rained more and more heavily.
d.比较级用于否定结构可表示“最…不过”,如:
I can't agree with you more.
e.最高级常用“the+最高级+比较范围”结构,比较范围为介词短语或从句,有时定冠词可省略,如:
They all came early but she came (the)
earliest of all.
