1.什么是形容词的原级？
表示修饰两种东西的程度是一样的,用as….as表示原级，译为:“和…一样”。
2.什么是形容词的比较级？
表示两者相比，一个比另一个更…，有比较级的句中有than,且仅限于两者比较。
形容词的原级和比较级
原级和比较级区分程度的不同：
原级是说明两个人物或事物的程度是一样。
比较级是区分两个人物或事物的程度不一样
大多数形容词和副词有三个等级：
原级、比较级、最高级。
一、形容词比较级的构成
1.构成的不规则变化:
2.构成的规则变化:
形容词和副词的比较级
1. 构成的不规则变化:
e.g. good / well – better – best
bad / badly – worse – worst
many / much – more – most
little – less – least
far – farther / further – farthest/ furthest
2. 构成的规则变化:
1) 单音节词和少数双音节词一般在词尾
后加-er 构成比较级 或-est构成最高级. 如：
原级 比较级 最高级
cold –—— colder –—— coldest
bright——— brighter———brightest
young—— younger—— youngest
2) 以字母 e 结尾的词只加 –r 或-st 构成
比较级和最高级。
原级 比较级 最高级
nice ——— nicer –——— nicest
fine——— finer———— finest
large —— larger ———— largest
3) 形容词比较级后面往往用连词than连接另一个比较的人或事物, 但在上下文明确的情况下, 形容词比较级可单独使用。如：
My sister is tall, but my aunt is taller.
我姐姐个子高, 但我姑姑个子更高。
4) 进行比较的人和物必须是同一类。
My books are more than yours.
I have more books than you.
5) 多音节词和部分双音节词在词前加more或most。如：
delicious – more delicious
– most delicious
interesting – more interesting
– most interesting
important—more important
—most important
讲述某人或某物自身情况时用原级。
基本句型：主语+ 谓语 + 形容词/副词原级 +….
He is very old now. 他现在很老了。
They ran quite fast. 它们跑得相当快。
The weather looks rather bad.
天气看上去相当糟
I am so happy. 我是如此的快乐。
原级的用法
表示两者之间没有差别时,使用句型：
主语(第一个人物) + 谓语动词 + as + 形容词/副词原级 + as + 第二个人物 +….
如：He is as excited as his younger sister.
他和他妹妹一样兴奋。
Lily rode her bike as slowly as an old
lady. 莉莉骑车像老太太一样慢。
They picked as many apples as the farmers
(did). 他们摘的苹果和农民一样多。
表示第一个人比不上第二个人时,使用句型:
主语(第一个人物) + 谓语动词(否定式) + as / so + 形容词/副词原级 + as
He is not so / as excited as his younger sister.
他没他妹妹那么兴奋。
Lily did not ride her bike so / as slowly as an old lady.
莉莉骑车不像老太太那样慢。
They didn’t pick so / as many apples as the farmers (did). 他们摘的苹果不如农民多。
比较级的用法
讲述两者有差异, 第一个人物超过第二个人
物时用比较级。
基本句型：主语(‘A’)+谓语动词+形容词/副词比较级+than+主语(‘B’)+….
e.g. A modern train is faster than a car.
现代的火车比轿车快多了。
This book didn’t cost me more than that one.
这本书花费我的钱不比那本多。
在形容词比较级前还可用much, even, still, a little来修饰, 表示“…的多”, “甚至…”, “更…”, “…一些”。
e.g. 1) This city is much more beautiful than before.
2) She’s a little more outgoing than me.
3) It’s a little colder today.
3.“比较级＋and＋比较级”意为“越来越…” 。多音节比较级用“more and more＋形容词原级”形式。如：
It’s getting worse and worse.
The group became more and more popular.
4. “Which / Who is + 比较级…？”
比较A、B两事物, 问其中哪一个较……时用此句型
如：
Which T-shirt is nicer, this one or that one
Who is more active, Mary or Kate
Which one is more popular among students, going to concerts or going to movies
5. 使用形容词比较级时需注意以下几点：
1) than后面接代词时, 一般要用主格形式，但在口语中也可使用宾格形式。 如：
My brother is taller than I/me.
2) 当需要表示一方超过另一方的程度时，可以用much, a lot, a little, a bit, even, still等来修饰形容词比较级。
注意: 比较级不能用very, so, too, quite等修饰。如：
He is much more serious than Sam.
3) 重读闭音节词末尾只有一个辅音字母
时, 先双写这个辅音字母, 再加-er或-est。
如: big – bigger – biggest
thin – thinner – thinnest
4) 以“辅音字母+ y”结尾的双音节词，
先改y为i, 再加-er或-est。如：
easy – easier – easiest
happy – happier – happiest
