比較狀語從句

比較狀語從句

狀語從句指句子用作狀語時,起副詞作用的句子。比較狀語從句是其中的一種,主要運用於形容詞和副詞的原級、比較級及最高級的句子之中,原級:as…as(和……一樣),not so(as)…as …(和不一樣);比較級:more…than(更);最高級:The most…in/of, the + 形容詞+est…of/in。常用引導詞:as(同級比較),than(不同程度的比較);特殊引導詞:the more … the more … ; no … more than;not A so much as B。

作用


狀語從句起副詞作用。

連詞


引導比較狀語從句的連詞主要是 as 和 than,通過其它手段與它們結合便形成了各種不同的比較:
1.同級比較:
• as/so + 原級 + as 和...一樣,(其中 as/so 是副詞,意思是“同樣地”,后一個 as 是連詞),如:
• My hometown is as/so beautiful as Hangzhou
• no + 比較級 + than 最多和...一樣,只不過,如:
• I have no more than two dollars left in my pocket.我口袋裡只剩下兩元錢了.(有錢少的含義)
• not more than,不多於,如:
• I have not more than two dollars left in my pocket.我口袋裡頂多還有兩元錢.(沒有錢多錢少的含義)
• no less than 不亞於,至少和...一樣,如:
• He has got no less presents than I did last time.他收到的禮品不亞於我上次收到的.(有收到多的含義)
• not less than 不少於,如:
• He has got not less presents than I did last time.他收到的禮品不少於我上次收到的.(不包含多或少的含義)
2.優級比較:
• 比較級 + than,比...優上,如:
• Our class is bigger than yours.我們班的規模比你們的大.
• the 比較級 + the 比較級,越如何就越如何,如:
• The more we can do for you,the happier we will be.為你們做得越多我們就越感到高興.
3.差級比較:
• less + 原級 + than,不如,比...較差,如:
• This kind of food is less expensive than that one.這種食品不如那一種貴.
• not so + 原級 + as,不如,不及,如:
• The film today is not so interesting as the one yesterday.今天的電影不如昨天的那個有意思.
• than 比,as/so ...as 和...一樣,the more...the more 越...越...

舉例


通常由as或than引起,這類從句和大多數狀語從句不同,它們不修飾動詞,而是 修飾as,so,less,more等副詞,或其他比較級的詞,如 taller, harder.在這裡討論它們,不是作為動詞修飾語,而是作為一種狀語從句。包含這類從句的句子通常為L,即從句在後:
She is as tall as I(or me).
He works as hard as his brother(does).
He does not work as hard as his brother.
He does not work so hard as his brother.

比較狀語從句(adverbial clause of comparison)從某種角度上說,它也是一種方式狀語從句,它通常可和以下關聯詞來引導as(或so)...as, than, according as, in proportion as等。如:
as...as...
