形容词和副词的比较等级复习
一、形容词和副词的原级就是原形.
1. very / so / too / quite +原级（副词修饰形容词，副词）
She is very beautiful. He works quite hard.
2.A+be +as +原级 +as+ B.
3.A+be not+as/so+原级 as+B.
Lucy is _________Lily. lucy和lily一样高。
Tom isn’t _______________Jim. Lucy没有lily高。
二. 形容词和副词的比较级
（一）主要用于两者比较。表示较……或更……一些的意思。
常用far, even，much，a lot, a bit, a little等修饰。
（三）形容词和副词的比较级的用法：
1.主语+谓语动词+adj./adv. +比较级+ than+ 对比成分
即：A +（be;实义动词）+比较级+than +B
2.比较级+and+比较级 或 more and more原级
3. the +比较级，the+比较级
4.比较级+than any (other)+单数名词
表示同一事物在某一范围内进行比较
5. the + 比较级+ of the two…是两者中更…的一
6. Which / Who is + 比较级， A or B ?
比较A、B两事物, 问其中“哪一个较……”
1. His computer is cheaper than I. （×）
2. Mary is very younger than her brother. （×）
3. Shanghai is bigger than any city in China. （×）
4. Tom is taller of the two brothers. （×）
[烦恼一] 同类事物才能比较
[烦恼二] 错用修饰语。修饰比较级只能用much / even / far / a little.不能用very / so / too / quite来修饰。
[烦恼三] 同一事物不能比较。同一事物在某一范围内进行比较，常用结构比较级+than any (other)+单数名词
[烦恼四] 表示“…是两者中更…的一个”时, 用
“the + 比较级+ of the two”结构。the 不可缺。
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) 上下文明确的情况下,形容词比较级可单独，使用不用连词than 。如：
My sister is tall, but my aunt is taller.
4) .“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”如：It’s getting worse and worse.
The group became more and more popular.
5). “Which / Who is + 比较级， A or B？”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?
三．形容词和副词的最高级
一）主要用于三者或三者以上进 行比较表示：某人或某物在某范围内最……的意思。
（二）结构：
1. 主语+be/行为动词+the 最高级+in(of/among)…
1) in表示环境范围，of /among 表示对象范围
2) 形容词最高级前有物主代词时，不加the
3) 副词最高级前the也可以省掉。
1）He is the tallest in his class.
2) He is the tallest of (all)the /the three boys
3) He studies the hardest among them /of all the students.
2. Which / Who is + the 最高级，A, B or C…？
比较A、B、C三事物, 问其中哪一个最……
1) Who is the tallest, Lucy，Mary or Kate?
2) Which one is the most popular among students, going to concerts ， going to movies or playing computer games?
3. one of +the +最高级+名词复数
4. the +序数词+最高级+名词
5.“比较级+than any other+单数名词”结构表示最高级概念
6.最高级前的修饰语也可以是first, second, third……
Huanghe is the second longest river in China.
注意以下表达式的含义：the same…as(和……一样)， had better(最好)，less than(不到)，more or less(或多或少)，rather than(而不是)，the more…the more/less(越……就越……) sooner or later(迟早)
最后：一定要判断来用形容词的比较等级，还是副词的比较等级。副词主要用来修饰行为动词的，经常跟在行为动词之后修饰。而形容词主要在系动词之后，名词之前修饰。（难点）
Tom does his homework more carefully than Lily.
Tom is more careful than Lily.
