形容词和副词有三个等级:原级、比较级和最高级
1. 原级
1. 表示两者在某一方面相同
as + 形容词或 副词原形 + as
e.g. This dress is as beautiful as that one.
Linda sings as well as Amy.
2. 表示一方在某一方面不及另一方时
not as / so + 形容词或副词原形 + as
e.g. Tom isn’t as / so tall as me.
I don’t sing as / so loudly as my sister.
3. 原级前可用very,quite,too等副词修饰
e.g. I’m very hungry.
My sister runs quite fast.

2. 比较级
1. 标志词:than
e.g. I’m more outgoing than you.

2. 用法(表示两者(人或事物)的比较)
(1)两者中“谁更……”
(2) 特殊疑问词+谓语+比较级,A or B?
e.g. Which is better, the red dress or the black dress?

(3)much,even,still,rather,any,far,a little, a lot, a bit等词用来修饰比较级。可以加强语气或表示比较程度。
(4)the + 比较级 + …… + the +比较级

(7)比较级必须在同类中进行,即人与人比,物与物比,而且比较结构前后的词语要对称,特别注意在than或 as 之后不要漏掉可能出现的替代词 that ,those, one ,ones.
例如:The weather of Beijing is colder than that of Shanghai.
.The new building is higher than the old one.

(8)3.表示“A比B大几岁/长几米/高多少/年轻多少/多多少倍”等,用“A+谓语+数量+比较级+than+B ”。
eg:I am two years older than my sister.我比我的妹妹大两岁。
(9).同一类人或事物在某一范围内进行比较时,常用“主语+谓语+比较级+than any other+名词单数” 表示“……比其他任何一个……都……”。
eg:Shanghai is bigger than any other city in China. 在中国,上海比其他城市都大。(上海是中国最大的城市。)
(10) A+谓语+less+多音节形容词或副词原级+than B,意为“A在某个方面不及B”=A+谓语+ not as(so)+形容词(副词)原级+as+B。
