□注意事項(xiàng):
該句型為比較級(jí)的最基本句型。只要看到than,即可確定前面使用比較級(jí)。
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(jí) + than
□注意事項(xiàng):
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(jí),后面必須跟形容詞的原級(jí),否定就造成了比較級(jí)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(jí)+ as
□注意事項(xiàng):
該句型表示對(duì)比的兩者程度相當(dāng),as之間必須跟形容詞或副詞的原級(jí),決不能使用比較級(jí)。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(gè)as前的動(dòng)詞,如果是系動(dòng)詞(如be,感官動(dòng)詞look, sound, smell, taste, feel等),那么就用形容詞的原級(jí),如果前面的動(dòng)詞是一般的實(shí)義動(dòng)詞,那么就必須用副詞的原級(jí)修飾動(dòng)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(shū)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(gè)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(jí)+ as
□注意事項(xiàng):
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(gè)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(jí)+ in / of / among +比較范圍
□注意事項(xiàng):如果這里為副詞最高級(jí),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(lèi)之間”,of后面的詞與主語(yǔ)同類(lèi),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(méi)有修飾語(yǔ)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(jí)+可數(shù)名詞復(fù)數(shù)形式
□注意事項(xiàng):
one of有三大考點(diǎn):1. 后跟形容詞最高級(jí);2. 后接可數(shù)名詞復(fù)數(shù)形式;3. 作主語(yǔ)時(shí)主語(yǔ)為one,謂語(yǔ)動(dòng)詞用單數(shù)形式。
One of the smallest dinosaurs was about one metre long.
◇句型七:比較級(jí)+and +比較級(jí) / more and more +多音節(jié)詞的原級(jí)
□注意事項(xiàng):
該句型表示“越來(lái)越……”,如果該形容詞比較級(jí)構(gòu)成形式加er,則用前面的句型;如果該形容詞比較級(jí)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(jí)+…, the +比較級(jí)+…
□注意事項(xiàng):
該句型意思為“越……就越……”,表示兩種情況同時(shí)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(xiàng):
該句型沒(méi)有運(yùn)用比較級(jí),但也是對(duì)兩者事物進(jìn)行比較。注意前后比較需在同類(lèi)事物中進(jìn)行。
My schoolbag is different from yours.
◇句型十:the same as… / the same…as…
□注意事項(xiàng):
該句型同樣沒(méi)有運(yùn)用比較級(jí),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(jí)+than + any other +名詞單數(shù)形式
□注意事項(xiàng):
any other 后面跟單數(shù)名詞,表示“任何別的”,即主語(yǔ)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(yǔ)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(guó)這個(gè)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(jí)+than + the other +名詞復(fù)數(shù)形式
□注意事項(xiàng):
該句型相當(dāng)于any other +名詞單數(shù)形式,常用來(lái)進(jìn)行同義句改寫(xiě)。該句型與句型十一雖然波表面上都是比較級(jí),但實(shí)際上相當(dāng)于最高級(jí)。以下三句表達(dá)的是同一個(gè)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(shí),比較的對(duì)象應(yīng)是同類(lèi)事物,不同類(lèi)的事物之間無(wú)法進(jìn)行比較。
