　　重点句型归纳

　　句型一：形容词或副词比较级+than…注意事项：该句型为比较级的最基本句型。只要看到than，即可确定前面使用比较级。He is taller than I am.他比我高。The boy does his homework more carefully than the girl.这个男孩做作业比这个男孩认真。

　　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，less本身就是little的比较级，后面必须跟形容词的原级，否定就造成了比较级的重复使用。This computer is less expensive than that one.这台电脑比那台便宜。

　　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 asthat one.这节课和那节课一样容易。Lucy talks with old people as politely as her sister.露西和老人交谈和与他妹妹交谈一样礼貌。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 askind a person as his father.他和他爸爸一样都是善良的人。as + many/much+不可数名词/可数名词复数+asI cancarry as much paper as you can.你能搬多少纸，我也能。I haveas many books as you do.我的书和你的一样多。We’ll give you as much help as we can.我们将尽我们所能给你帮助。其它几个关于as…as的句型：as … as one can：尽其所能He began to run as fast as he could.他尽其所能跑得快。as … as possible：尽可能Pleasehelp us as quickly as possible.请尽可能地帮助我们。as soon as…一……就……He will callme as soon as he comes here.他一来这儿就会给我打电话。

　　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as可以换为so。This classroom is not asbright as yours.这个教室没有你们的明亮。I cannot run as fast asyou.我跑步不如你快。

　　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 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 Yangtze River(The Changjiang River) is the longest river in our country.长江是我们国家中最长的河流。Peter is the tallest of thesix students.皮特是六个学生中最高的一个。This picture is the mostbeautiful among these.在这些画中，这张画是最美的。
