对两者进行比较时，形容词或副词要用比较级的形式；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。
形容词和副词的比较级、最高级
1. 形容词和副词的比较级的构成(规则变化)
一般在词尾加-er tall→taller fast→faster
以字母e结尾的词，在词尾加-r fine→finer
late→later
nice→nicer
以重读闭音节结尾的词，如末尾只有一个辅音字母时，先双写该辅音字母，再加-er big→bigger
hot→hotter
thin→thinner
以“辅音字母+y”结尾的词，先把 “y”变成 “i”, 再加-er lazy→lazier
early→earlier
大部分双音节或多音节单词, 一般在单词前加more quickly→ more quickly
strongly→more strongly
carefully→more carefully
interesting→more interesting
如: bad/ill/badly → worse， good/well → better，
much/many → more, little → less, far → further/farther
有些形容词和副词的比较级的构成属于不规则变化，需单独记忆。
1) 表示两者(人或事物)的比较，常用句型: “比较级+than+比较的对象”。
e.g. He works harder than his brother.
2) 形容词和副词的比较级有时可以单独使用。
e.g. My sister is tall, but my cousin is taller.
3) 形容词和副词的比较级前可以用a little，much等修饰。
e.g. Tom is a little / much shorter than Tim.
4) 同一范围内，“ ... + 比较级 + than any other + 单数名词”表示“……比其他的任何……都……”。
e.g. It’s better than any other place.
2. 形容词和副词的比较级的用法
3. 形容词和副词的最高级构成(规则变化)
一般在词尾加-est tall→tallest fast→fastest
以字母e结尾的词，在词尾加-st fine→finest
late→latest
nice→nicest
以重读闭音节结尾的词，如末尾只有一个辅音字母时，先双写该辅音字母, 再加-est big→biggest
hot→hottest
thin→thinnest
以 “辅音字母+y”结尾的词，先把 “y”改为 “i”, 再加-est lazy→laziest;
early→earliest
大部分双音节和多音节单词, 一般在单词前加most quickly→ most quickly
strongly→most strongly
carefully→most carefully
interesting→most interesting
同样, 有些形容词和副词的最高级的构成属于不规则变化。
如：bad/ill/badly → worst， good/well → best，
much/many → most, little → least,
far → furthest/ farthest
4. 形容词、副词的最高级句子结构
