三、单元语法
一、形容词和副词的比较级
大多数形容词和副词有三个等级：原级、比较级和最高级。 比较级用于两者(人或事物)的比较，表示“更…...”，用于说明“前者比后者更……”。than 是比较级句型的标志词。
1、形容词和副词的比较级的构成
分类 构成方法 示例
规则变化 一般情况 在词尾加-er new→newer； fast →faster
以字母e结尾的词 在词尾加-r fine→finer；late→later
词尾只有一个辅音字母的重读闭音节词 先双写该辅，再加-er hot→hotter；thin→thinner slim →slimmer
以“辅音字母+y”结尾的双音节词 先变y为i，再加-er early→earlier； happy→happier
多音节词和部分双音 在词前加more useful→more useful； carefully→more carefully
不规则变化 good/well→better； bad/badly→ worse： many/much→more； little→less； far→farther/further
2、形容词和副词的比较级的用法
(1) A+动词+比较级+than+B “A比B更…’”
用于两者之间的比较，表示“其中一个比另一个更…...” 后面用 than 引出比较的对象，即“比较级十than”结构。当than 前后所使用的动词相同时，通常用助动词代替后面的动词，该助动词可以省略。
He is more popular than Jim in the school. 在学校里他比吉姆更受欢迎。
I like swimming better than Bill (does). 我比比尔更喜欢游泳。
(2)A+系动词+the+比较级+of the two(十复数名词)“A是两者中比较……的”
Ann is the more outgoing of the two. 安是这两人中比较外向的。
(3)比较级+and+比较级 “越来越…...”
The+比较级， ......，the+比较级...... “越……就越…...”
Our city is becoming more and more beautiful.　我们的城市正变得越来越漂亮。
The more you eat, the fatter you are.　你吃得越多，就越胖。
(4)表示两个事物间的对比选择：Which/Who+动词+比较级，A or B
Who is better at English, Bob or Mike 　鲍勃和迈克谁更擅长英语
(5)比较级可表达最高级含义
Tom is taller than any other student in our class.　汤姆是我们班最高的学生。
【拓展】
在形容词和副词的比较级前，可以用 much、a little 等修饰。
My friend Bill is much smarter than me.　我的朋友比尔比我聪明得多。
　
二、as .. as...
　　as ... as ... 意为“像······一样······”，两个 as 中间用形容词或副词的原级，用来进行同级比较，表示两者在某一方面相同。“not as/so+形容词或副词原形+as” 表示一方在某一方面不及另一方。
My pen is as new as your pen.　我的钢笔和你的钢笔一样新。
Lily isn't as/so careful in writing as Lucy.　在书写方面莉莉没有露西认真。
