19、较级。He is taller than I am.The boy does his homework more carefully than the girl.句型二： less +形容词的原级+ than注意事项：该句型表示“不如、不及”，特别需要注意的是，面必须跟形容词的原级，否定就造成了比较级的重复使用。less本身就是little的比较级，后This computer is less expensive than that one.句型三： as + 形容词或副词的原级+ as注意事项：该句型表示对比的两者程度相当，as 之间必须跟形容词或副词的原级，决不能使用比较级。此外，还要确定

20、使用形容词还是副词。确定的依据就是根据第一个as 前的动词，如果是系动词（如be，感官动词look, sound, smell, taste, feel等），那么就用形容词的原级，如果前面的动词是一般的实义动词，那么就必须用副词的原级修饰动词。This lesson is as easy as that one.Lucy talks with old people as politely as her sister.特别提醒： as as 之间也可以跟名词，句型如下： as + 形容词 + a/an + 单数名词 +asHe is as kind a person as his father.

21、 as + many/much+ 不可数名词 / 可数名词复数I can carry as much paper as you can.I have as many books as you do.We ll give you as much help as we can.他和他爸爸一样都是善良的人。+as你能搬多少纸，我也能。我的书和你的一样多。我们将尽我们所能给你帮助。其它几个关于asas as 的句型：asHebeganasPleasehelponetousrunasascan：asfastpossiblequickly尽其所能ashecould.：尽可能aspossible.换为 as

22、 soon as一就He will call me as soon as he comes here.句型四： not as/so +形容词或副词的原级+ as注意事项：该句型表示“前者不如后者”，往往可以与句型一和句型二替换。第一个so。as可以This classroom is not as bright as yours.I cannot run as fast as you.句型五： the + 形容词或副词最高级+ in / of / among +比较范围注意事项：如果这里为副词最高级，前面的the 常常省略。介词in 和 of 的用法完全不一样。in表示“在某一范围内”，如：in

23、 the classroom， in the world。 of 表示“在同类之间”，of 后面的词与主语同类，另名词前一般有冠词the 。among表示“在（三者或三者以上）之间”， among后接代词或没有修饰语的名词。The Changjiang River is the longest river in our country.Peter is the tallest of the six students.This picture is the most beautiful among these.句型六： one of +注意事项：one of 有三大考点：1.形容词最高级+可数名
