形容词、副词的比较级和最高级讲解与练习 当两种物体之间相互比较时，我们要用形容词或副词的比较级，当相互比较的物体是三个或三个以上时，我们就要用形容词或副词的最高级。 一、形容词、副词的比较级和最高级的变化规律： 1. 单音节形容词或副词后面直接加-er或-est
tall—taller—tallest fast—faster—fastest 2. 以-e结尾的单音节形容词或副词直接加-r或-st
large—larger—largest nice—nicer—nicest 3. 以-y结尾的形容词或副词，改-y为-i再加-er或-est
busy—busier—busiest early—earlier—earliest
4. 形容词或副词是重读闭音节时，双写最后的辅音字母，再加-er或-est
hot—hotter—hottest big—bigger—biggest 5. 多音节形容词或副词前面直接加more或most
delicious—more delicious—most delicious beautiful—more beautiful—most beautiful 6. 不规则变化
good (well)—better—best bad (badly)—worse—worst 二、形容词、副词的比较级和最高级的句子公式： 1、比较级：
形容词物体A + am / are / is + 形比 + than + 物体B. I am taller than you.
Pasta is more delicious than pizza.
副词物体A + 行为动词 + 副比 + than + 物体B.
Cheetahs run faster than goats. He studies better than me. 2、最高级：
1）物体A + am / are / is + the + 形最高级 + 比较范围（of + 人/物，in +地方）.
I am the tallest in the class.
Pasta is the most delicious food of the three.
2）物体A + 行为动词 + 副词最高级 + 比较范围（of + 人/物，in + 地
方）.
Cheetahs （猎豹）run fastest in the world. He studies best of us. 3） 常见比较级五句型：

4> \"The+形容词比较级..., the+形容词比较级...\表示 \" 越... 就越...\"。 The more you study, the more you know. 你学的越多, 就知道的越多。 5> \" 形容词比较级 + and + 形容词比较级 \表示 \" 越来越... \"。
The computer is cheaper and cheaper. 计算机越来越便宜。 4）最高级常见用法：

2> ~ + be + one of the +最高级 +复数名词, 表示\"最„„的„„之一\"。

3> \"„+ be +the + 序数词 +最高级 +单数名词 + 范围\表示\"„„
是„„.的第几„„\"。

形容词最高级前通常必须用定冠词 the，副词最高级前可不用。 形容词most前面没有the，不表示最高级的含义，只表示“非常”。 It is a most important problem. =It is a very important problem. 5）比较级中原级用法：

as +形容词+ a +单数名词 as + many/much +名词

3）用表示倍数的词或其他程度副词做修饰语时，放在as的前面。
This room is twice as big as that one. Your room is the same size as mine. 4）倍数+ as + adj. + as

You are taller than I.

1）要避免重复使用比较级。

（错）China is larger that any country in Asia.
（对）China is larger than any other countries in Asia. 3）要注意对应句型，遵循前后一致的原则。
The population of Shanghai is larger than that of Beijing. It is easier to make a plan than to carry it out. 4）要注意冠词加比较级的用法： 比较：

Which is the larger country，Canada or Australia？ She is taller than her two sisters.
