北京仁爱版英语7年级下册语法重点
◇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. 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,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.

◇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 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+as He is as kind 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+as I can carry as much paper as you can. 你能搬多少纸,我也能.
I have as 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.
☆as … as possible：尽可能 Please help us as quickly as possible.
☆as 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as可以换为so.
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 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 + 形容词最高级+可数名词复数形式
□注意事项： one of有三大考点：1. 后跟形容词最高级；2. 后接可数名词复数形式；3. 作主语时主语为one,
谓语动词用单数形式. One of the smallest dinosaurs was about one metre long.

◇句型七：比较级+and +比较级 / more and more +多音节词的原级
□注意事项：该句型表示“越来越……”,如果该形容词比较级构成形式加er,则用前面的句型；如果该形容词比较级加more构成,则用后面的句型.It is getting hotter and hotter. The girl is becoming more and more beautiful.

◇句型八：the +比较级+…, the +比较级+…
□注意事项：该句型意思为“越……就越……”,表示两种情况同时变化.
The more you eat, the fatter you will be. In the test, the more careful you are, the fewer mistakes you will make.


◇句型九：be different from
□注意事项： 该句型没有运用比较级,但也是对两者事物进行比较.注意前后比较需在同类事物中进行.
My schoolbag is different from yours.

◇句型十：the same as… / the same…as…
□注意事项： 该句型同样没有运用比较级,表示两者之间具有共同特性.注意这里的as和same为固定搭配,不
能随便变换. I don’t want to buy the same things as Amy did.

◇句型十一：比较级+than + any other +名词单数形式
□注意事项： any other 后面跟单数名词,表示“任何别的”,即主语在范围内,必须把自身从这一范围内除去,否则逻辑
上不通.如果主语不在这一范围内,那么要把other去掉,只用any即可.
Shanghai is larger than any other city in China. （上海在中国这个范围内,所以用any other）
Shanghai is larger than any city in Jiangsu. （上海不在江苏,所以只需用any）

◇句型十二：比较级+than + the other +名词复数形式
□注意事项： 该句型相当于any other +名词单数形式,常用来进行同义句改写.该句型与句型十一虽然波表面上都是比较级,
但实际上相当于最高级.以下三句表达的是同一个意思.
Daniel is the most hard-working student in our class.
Daniel is more hard-working than any other student in our class.
Daniel is more hard-working than the other students in our class.

特别提醒：表示两者(人或物)比较时,比较的对象应是同类事物,不同类的事物之间无法进行比较.
强调比较程度时,比较级可用的修饰词有：much, far, still, even, no, any, a lot, a little, a bit,等.
A kangaroo is even taller than a man.
Please come here a little earlier.
The job is far more difficult than he thought.
Li Lei jumps much farther than Jim does.
