□注意事項:
該句型為比較級的最基本句型。只要看到than,即可確定前面使用比較級。
He is taller than I am.
The boy does his homework more carefully than the girl.
◇句型二:less + 形容詞的原級 + than
□注意事項:
該句型表示“不如、不及”,特別需要注意的是,less本身就是little的比較級,后面必須跟形容詞的原級,否定就造成了比較級的重復(fù)使用。
This computer is less expensive than that one.
◇句型三:as +形容詞或副詞的原級+ as
□注意事項:
該句型表示對比的兩者程度相當,as之間必須跟形容詞或副詞的原級,決不能使用比較級。此外,還要確定使用形容詞還是副詞。確定的依據(jù)就是根據(jù)第一個as前的動詞,如果是系動詞(如be,感官動詞look, sound, smell, taste, feel等),那么就用形容詞的原級,如果前面的動詞是一般的實義動詞,那么就必須用副詞的原級修飾動詞。
This lesson is as easy as that one.
Lucy talks with old people as politely as her sister.
特別提醒:as…as之間也可以跟名詞,句型如下:
☆as +形容詞+ a/an +單數(shù)名詞+as
He is as kind a person as his father. 他和他爸爸一樣都是善良的人。
☆as + many/much+不可數(shù)名詞/可數(shù)名詞復(fù)數(shù)+as
I can carry as much paper as you can. 你能搬多少紙,我也能。
I have as many books as you do. 我的書和你的一樣多。
We’ll give you as much help as we can. 我們將盡我們所能給你幫助。
其它幾個關(guān)于as…as的句型:
☆as … as one can:盡其所能eg.He began to run as fast as he could.
☆as … as possible:盡可能 eg.Please help?us?as quickly as possible.
☆as soon as…一……就…… eg.He will call me as soon as he comes here.
◇句型四:not as/so +形容詞或副詞的原級+ as
□注意事項:
該句型表示“前者不如后者……”,往往可以與句型一和句型二替換。第一個as可以換為so。
This classroom is not as bright as yours.
I cannot run as fast as you.
◇句型五:the +形容詞或副詞最高級+ in / of / among +比較范圍
□注意事項:如果這里為副詞最高級,前面的the常常省略。介詞in和of的用法完全不一樣。in表示“在某一范圍內(nèi)”,如:in the classroom,in the world。of表示“在同類之間”,of后面的詞與主語同類,另名詞前一般有冠詞the。among表示“在(三者或三者以上)之間”,among后接代詞或沒有修飾語的名詞。
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 + 形容詞最高級+可數(shù)名詞復(fù)數(shù)形式
□注意事項:
one of有三大考點:1. 后跟形容詞最高級;2. 后接可數(shù)名詞復(fù)數(shù)形式;3. 作主語時主語為one,謂語動詞用單數(shù)形式。
One of the smallest dinosaurs was about one metre long.
◇句型七:比較級+and +比較級 / more and more +多音節(jié)詞的原級
□注意事項:
該句型表示“越來越……”,如果該形容詞比較級構(gòu)成形式加er,則用前面的句型;如果該形容詞比較級加more構(gòu)成,則用后面的句型。
It is getting hotter and hotter.
The girl is becoming more and more beautiful.
◇句型八:the +比較級+…, the +比較級+…
□注意事項:
該句型意思為“越……就越……”,表示兩種情況同時變化。
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
□注意事項:
該句型沒有運用比較級,但也是對兩者事物進行比較。注意前后比較需在同類事物中進行。
My schoolbag is different from yours.
◇句型十:the same as… / the same…as…
□注意事項:
該句型同樣沒有運用比較級,表示兩者之間具有共同特性。注意這里的as和same為固定搭配,不能隨便變換。
I don’t want to buy the same things as Amy did.
◇句型十一:比較級+than + any other +名詞單數(shù)形式
□注意事項:
any other 后面跟單數(shù)名詞,表示“任何別的”,即主語在范圍內(nèi),必須把自身從這一范圍內(nèi)除去,否則邏輯上不通。如果主語不在這一范圍內(nèi),那么要把other去掉,只用any即可。
Shanghai is larger than any other city in China. (上海在中國這個范圍內(nèi),所以用any other)
Shanghai is larger than any city in Jiangsu. (上海不在江蘇,所以只需用any)
◇句型十二:比較級+than + the other +名詞復(fù)數(shù)形式
□注意事項:
該句型相當于any other +名詞單數(shù)形式,常用來進行同義句改寫。該句型與句型十一雖然波表面上都是比較級,但實際上相當于最高級。以下三句表達的是同一個意思。
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.
特別提醒:表示兩者(人或物)比較時,比較的對象應(yīng)是同類事物,不同類的事物之間無法進行比較。
