形容词、副词的最高级
当我们要将三个或三个以上的事物进行比较时，可以用形容词或副词的最高级形式来表达。
1.形容词和副词最高级的变化形式
（1）形容词、副词最高级的规则变化：
类别 构成方法 举例
单音节和少数双音节单词 一般在词尾加-est tall→tallest, fast→fastest
以字母e结尾的词直接加-st fine→finest, late→latest
以重读闭音节结尾的词，如末尾只有一个辅音字母，应先双写该字母，再加-est big→biggest, thin→thinnest
以“辅音字母+y”结尾的词，先把y改为i，再加-est easy→easiest, early→earliest
续表
类别 构成方法 举例
大部分双音节和多音节单词 在单词前加most careful→most careful
slowly→most slowly
dangerous→most dangerous
carefully→most carefully
（2）常见形容词、副词最高级的不规则变化：
【注意】形容词的最高级前通常要加定冠词the； 副词的最高级前可加，也可不加。
原级 最高级
good，well best
bad / ill, badly worst
many / much most
little least
far farthest / furthest
2.最高级的基本用法
（1）形容词 / 副词最高级+in / of / among短语。如：
Jack is the tallest boy in our class.杰克是我们班个子最高的男生。
Tom lives (the) closest to school of all my classmates.在我所有同学中，汤姆住得离学校最近。
（2）“Who / Which+be+the+形容词最高级，A, B or C ”表示“A、B和C，哪个 / 谁最……”。如：
Which is the biggest, the sun, the moon or the earth 太阳、月亮和地球,哪一个最大？
（3）“the+序数词+形容词最高级+单数可数名词” 表示“第几……的”。如：
The Yellow River is the second longest river in China.黄河是中国第二长河。
