as可以引導(dǎo)的定語(yǔ)從句

  導(dǎo)語(yǔ):英語(yǔ)單詞as可作關(guān)系代詞,下面小編講解as可以引導(dǎo)的定語(yǔ)從句,歡迎參考。

  as作關(guān)系代詞時(shí),引導(dǎo)定語(yǔ)從句在從句中充當(dāng)主語(yǔ)、賓語(yǔ)、介詞賓語(yǔ)或表語(yǔ),既可以指人,也可以指物。

  (1)as引導(dǎo)定語(yǔ)從句時(shí),有如下結(jié)構(gòu):“the same …as”,“such …as”, “as…as”“so many (much, few, little)…as”,譯作“像……一樣的人(或物)”。例如:

  This is such an easy novel as you can read.

  這本小說(shuō)很容易,你能讀得懂。

  They have never read so many books as I read last year.

  他們從來(lái)都沒(méi)有讀過(guò)像我去年讀過(guò)的那些書(shū)。

  (2)as單獨(dú)引導(dǎo)定語(yǔ)從句時(shí),修飾整個(gè)主句或主句中的一部分,可以放在句首、句中或句末。當(dāng)as在從句中作主語(yǔ)時(shí),從句的謂語(yǔ)通常是被動(dòng)語(yǔ)態(tài)或系表結(jié)構(gòu);as在從句中作賓語(yǔ)時(shí),從句的謂語(yǔ)常用“情態(tài)動(dòng)詞+動(dòng)詞原形”構(gòu)成。常見(jiàn)的結(jié)構(gòu)如下:

  as is known to all 眾所周知

  as has been said above 如上所述

  as was expected 正如預(yù)料的那樣

  as has been pointed out 正如指出的那樣

  as we all can see (know, hear)正如大家看到的(知道的、聽(tīng)到的)那樣。例如:

  As is known to everybody, the moon travels round the earth once every month.

  眾所周知,月球每個(gè)月繞地球轉(zhuǎn)一周。

  引導(dǎo)限制性定語(yǔ)從句:

  用在 such, same, as 等之后,引導(dǎo)限制性定語(yǔ)從句。如:

  I live in the same place as Tom does. 我和湯姆住在同處。

  He’s not such a fool as he looks. 他并不像看上去的那樣愚蠢。

  He smokes as expensive a cigarette as he can afford. 他抽一種他買(mǎi)得起的最貴的煙。

  引導(dǎo)非限制性定語(yǔ)從句:

  (2) 單獨(dú)用作關(guān)系代詞,引導(dǎo)非限制性定語(yǔ)從句,可放在主句之前、之后或中間,且主從句之間一般要用逗號(hào)隔開(kāi)。如:

  As was expected, he succeeded at last. 正如我們所料,他終于成功了。

  I had coffee after dinner, as is my usual practice. 我飯后喝咖啡,這是我的.習(xí)慣。

  Freddie, as might be expected, was attending the conference. 弗雷迪在參加會(huì)議,這是可以預(yù)料到的。

  as與which的用法區(qū)別:

  ① 引導(dǎo)限制性定語(yǔ)從句的區(qū)別:as用作關(guān)系代詞引導(dǎo)限制性定語(yǔ)從句時(shí),它通常只用于 such, same, as 等之后,而which 用作關(guān)系代詞引導(dǎo)限制性定語(yǔ)從句時(shí),則用于除 such, same, as 之外的其他結(jié)構(gòu)。

 、 引導(dǎo)非限制性定語(yǔ)從句的區(qū)別:which引導(dǎo)非限制性定語(yǔ)從句時(shí),通常只能位于主句后,而as引導(dǎo)的非限制性定語(yǔ)從句位于主句之前、之后或中間。

  根據(jù)從句謂語(yǔ)動(dòng)詞的特點(diǎn)來(lái)看,as在定語(yǔ)從句中作主語(yǔ)時(shí),從句謂語(yǔ)通常要有be或別的系動(dòng)詞,但which不受此限制。如:

  Li Ming was late, which (=and this) made Mr. Zhang very angry. 李明遲到了,這件事使張先生非常生氣。(不可用as)

  根據(jù)句意的邏輯性來(lái)看,as引導(dǎo)的定語(yǔ)從句只表示一個(gè)眾所周知或意料之中的事,但which不受此限制。如:

  He married her, as [which] was natural. 他和她結(jié)婚了,這是很自然的。

  He married her, which was unexpected. 他和她結(jié)婚了,這是出乎意料的。(不可用as)
