最高级主要用于三者或三者以上进行比较。
规则变化

tall—_____—______ long—______—______

④重读闭音节（末尾只有一个辅音字母）
双写辅音字母再加 -er或 -est

分别在原级前加more构成比较级和most构成最高级

原级 比较级 最高级

不规则变化

级前可用the，也可省略。
（2）比较级前常用的修饰语有 far，even，a lot，
a bit，much等。
使用比较等级应注意的几点：
二、大数字的表达与读法
1000以上的基数词的表示法：
先从右至左数，每三位数加一个逗号（即以 此把数目分为若干段）。
第一个逗号前的数为 thousand（千）；
第二个逗号前的数为 million（百万）；
第三个逗号前的数为 billion（十亿）。
9,883
nine thousand, eight hundred and eighty-three
65,359
sixty-five thousand, three hundred and fifty-nine
265,468
two hundred and sixty-five thousand, four hundred and sixty-eight
60,263,150
sixty million, two hundred and sixty-three thousand, one hundred and fifty
1. 英语没有“万”这个单位，要表示“万”须
借用 thousand，如“一万”用“十个千
（ten thousand）” 表示，“十万”用“百个千
（one hundred thousand）”表示。
2. 在hundred后通常加上连词and。若读数中百位
数为0，则在thousand后加and。
