Structure : as ... as... 像..….一样
e.g. Tim is as tall as Tom.
2. 比较级 (用于两者之间的比较):
Structure：形容词比较级＋ than ...
e.g. This box is bigger than that one.
3. 最高级(用于三者或三者以上的比较):
Structure:
the + 形容词的最高级＋of / in ...
e.g. Tom is the heaviest in our class. He is the most popular in our school.
规则变化
1) 一般情况下，单音节或双音节的形容词/副词比较级＋er， 最高级＋est。如:
clever — cleverer — cleverest
few — fewer — fewest
small — smaller — smallest 等。
2) 以e结尾的词，比较级＋r，最高级＋st 即可。 如：
nice — nicer — nicest
cute — cuter — cutest
large — larger — largest
3) 以辅音字母＋y结尾的变y为i＋er或est 如: easy — easier — easiest
happy — happier — happiest
再如：early, busy, heavy, dirty, lazy 也如此。
4) 重读闭音节，单辅音结尾的，双写这个辅音字母＋er 或 est的词：
① fat — fatter — fattest
② thin — thinner — thinnest
③ hot — hotter — hottest
④ wet — wetter — wettest
⑤ big — bigger — biggest
5) 多音节和部分双音节的词需要在形容词
原级前＋more 构成比较级，＋the most 构
成最高级。如：
beautiful － more beautiful － the most beautiful
又如: delicious, popular, important, interesting, expensive, creative
双音节的词如: careful － more careful － the most careful useful － more useful － the most useful
少数单音节词也是这样，如：
pleased — more pleased — the most pleased
tired — more tired — the most tired

bad — worse — worst
many/much — more — most
far — farther —farthest (距离远)
far — further — furthest (程度深)
old — elder — eldest (长幼)

三者或三者以上相比，表示最高程度时，用“the + 最高级”的结构表示。这种句式一般常有表示比较范围的介词短语。例如：
Zhang Hua is the tallest of the three.
He works (the) hardest in his class.
2. 最高级可被序数词以及 much，by far，nearly，almost，by no means，not quite，not really，nothing like 等词语所修饰。例如：
This hat is by far／much／nearly／almost／not nearly／by no means／not quite／nothing like the biggest. How much did the second most expensive hat cost
3. 表示“最高程度”的形容词，如 excellent，extreme，perfect等，没有最高级，也不能用比较级。
4. 形容词最高级修饰作表语或介词宾语的名词、代词时，被修饰的词往往省略。
e.g. He is the tallest (boy) in his class.
5. 作状语的副词最高级前可以不加定冠词。
e.g. Of all the boys he came (the) earliest.
比较级考点
① 比较级修饰问题 a little, a bit, even, still, much, a lot, far 等可修饰比较级。
e.g. Tom is a little taller than Jim. This book is much more interesting than that one.
② 同级比较
e.g. The weather in Beijing is colder than that in Xi’an. ③ the + 比较级
e.g. Lucy is the fatter of the two girls.
④ “a/an + 比较级” 表示“又一，再一”
e.g. Lily has a doll, but she wants a bigger one.
⑤ 隐性比较（没有than的情况）
e.g. Who runs faster, Lucy or Lily You’d better come earlier next time. He worked hard last term, but he works even harder this term.
⑥ 越来越......
比较级 + and + 比较级
b. the + 比较级 + 句子，the + 比较级 + 句子
e.g. It’s getting colder and colder. The more you exercise, the better you are.
2. 最高级考点
说明：形容词的最高级前必须加the；副词的最高级前省略the。
① 范围问题
e.g. Tom is the tallest student in the class. Spring is the best season of the year.
② “......之一”问题
e.g. Beijing is one of the biggest cities in the world.
③ “the + 序数词 + 最高级”
e.g. I think he is the second tallest boy in his class.
3. 比较级和最高级的转换
e.g. Tom is the tallest student in the class.
= Tom is taller than any other student in the class.
= Tom is taller than all the other students in the class.
= No other students are taller than Tom.
总结：① any other + 名词单数
the other + 名词复数
② 否定 + 比较级 = 最高级
比较级 + 极限 = 最高级
同级比较
① as + adj./adv. + as
e.g. She is as thin as Lily.
He writes as carefully as Linda.
② not + as/so + adj./adv. + as
e.g. Tony didn’t run so fast as Carter.
