名师点拨
英语中的形容词在表示“更……”时，要用其比较级；在表示“最……”时，要用其最高级；原来的形式则称为原级。
7
形容词的比较级和最高级
1.形容词比较级和最高级的构成
(1)规则变化
构成方法 原级 比较级 最高级
一般单音节词在词尾加-er或-est tall taller tallest
以e结尾的词只在词尾加-r或-st nice nicer nicest
以辅音字母结尾的重读闭音节词，双写词尾的辅音字母，再加-er或-est big bigger biggest
构成方法 原级 比较级 最高级
以“辅音字母+y”结尾的双音节词，先改y为i，再加-er或-est happy happier happiest
部分双音节和多音节词，在单词前面直接加more或most important more important most important
续 表
（2）不规则变化
原级 比较级 最高级
good / well better best
bad / badly / ill worse worst
many / much more most
little less least
far farther / further farthest / furthest
2.形容词比较级的用法
(1)表示两者进行比较时用形容词比较级，其结构为“A+谓语动词+形容词比较级+than+B.”。如：
Sam's sister is taller than mine. 萨姆的妹妹比我的妹妹高。
The result was more perfect than what we imagined. 结果比我们想象的更完美。
【注意】为了避免重复，在从句中常用the one, that, those等词来替代前面出现过的名词，其中the one替代可数名词单数形式，the ones或those替代可数名词复数形式，that替代不可数名词。
(2)表示程度的副词，如“两多 (a lot / much)两少(a bit / a little)”, even,far以及a few, still, rather等可以修饰形容词的比较级，表程度。如：
She's much / even / a lot / far healthier than she used to be. 她比过去要健康得多。
I think I'm a little / a bit better today. 我想我今天更好一点了。
(3)表示两者之间进行选择时，用句型“Which / Who is+形容词比较级，A or B ”表示。如：
Who is taller, Li Ming or Wang Tao 谁更高，李明还是王涛？
Which sweater is more beautiful, the yellow one or the pink one 哪件毛衣更漂亮，黄色的还是粉色的？
(4)表示“越来越……”时，用“比较级+and+比较级”表示，多音节词和部分双音节词用“more and more+形容词原级”表示。如：
It's getting warmer and warmer in spring. 春天天气越来越暖和了。
Our hometown is becoming more and more beautiful. 我们的家乡越来越漂亮了。
(5)表示“越……，越……”时，用“the+比较级，the+比较级”结构。如：
The sooner you come, the better. 你来得越早越好。
The more worried you are, the less happy you'll become. 你越焦虑，就会越不开心。
3.形容词最高级的用法
(1)表示三者或三者以上的人或物进行比较时，用最高级形式。形容词最高级前必须加定冠词the，句末常跟一个in / of 短语来表示范围。如：
The Yangtze River is the longest river in China.长江是中国最长的河流。
He is the strongest of the three boys. 他是三个男孩子中最强壮的一个。
（2）表示在三者或三者以上的人或物中进行选择时，用“Which/Who is+the+形容词最高级，A, B or C ”结构。如：
Which city is the most beautiful one, Beijing, Shanghai or Guangzhou 哪个城市最漂亮，北京、上海还是广州？
（3）表示“最……的……之一”时，用“one of the+形容词最高级+复数可数名词”结构。如：
He is one of the most popular singers. 他是最受欢迎的歌手之一。
(4)形容词最高级前面可以加序数词，表示“第几……的”。如：
Qomolangma is the first highest mountain in the world. 珠穆朗玛峰是世界第一高山。
Billy is the second tallest boy in our class. 比利是我们班第二高的男孩。
（5）形容词最高级前面可以有物主代词、指示代词、名词所有格等修饰，但此时不能再用定冠词the。如：

Yesterday was his busiest day. 昨天是他最忙的一天。
