定語從句中as的用法簡述
定語從句的引導(dǎo)詞很多,大致可以分為關(guān)系代詞和關(guān)系副詞,其中,關(guān)系代詞里較為常見的有that, which, as等,這幾個關(guān)系代詞用法比較多,也有許多需要特別注意的地方,小編建議大家逐個記憶,不要記混,下面我們來看一下as的用法。
as引導(dǎo)非限制性定語從句時有許多常用句式:
As is known to all, the earth moves around the sun. 眾所周知,地球圍著太陽轉(zhuǎn)。(as is known to all 眾所周知)
As is reported in the newspaper, the economic of our country has increased in last year. 正如報紙所報道的,我們國家的經(jīng)濟在去年有所增長。(as is reported in the newspaper 如報紙所報道的)
As is said above,this plan can be carried out totally. 綜上所述,這項計劃完全可以實施。( as is said above 綜上所述)
As was expected, he was elected as the chairman. 正如預(yù)料的那樣,他當(dāng)選為主席。(as was expected正如預(yù)料的那樣)
as引導(dǎo)限制性定語從句時,需要注意兩個結(jié)構(gòu):
such....as表示“像……這(那)樣”
He is such an unselfish man as we respect.他像我們所尊敬的那種無私的人。
the same...that...表示同一人或物,而the same...a(chǎn)s...表示同種類的東西,兩者都引導(dǎo)定語從句,試比較下列兩個句子:
This is the same pencil that I lost. 這支鉛筆就是我丟的那一支。This is the same pencil as I lost. 這支鉛筆跟我丟的那支筆一模一樣。
As不只在引導(dǎo)定語從句時有多種結(jié)構(gòu),其實它本身就是一個非常靈活常用的單詞,在多個英語學(xué)習(xí)版塊中都能見到它,雖然as只是一個小詞,但我們真的應(yīng)該好好了解一下它的用法。
