as的使用方法與分類

  在英語語句中經(jīng)常出現(xiàn)as的單詞,那么as要如何正確使用呢?以下是由學習啦小編整理關于as的用法的內(nèi)容,希望大家喜歡!

  as的用法

  一、 as作連詞的用法:

  1. 作"當……的時候",引導時間狀語從句。注意與when、 while的用法區(qū)別。

  ① when作"當……的時候"解,可以指較短的(一點)時間,也可指一段時間。如:

  When he was at college, he could speak several foreign languages.

  When the clock struck twelve, all the lights in the street went out.

 ?、?while常表示一段較長的時間或一個過程,強調(diào)主句謂語動詞與從句謂語動詞同時發(fā)生。如:

  Work while you work. Play while you play.

 ?、?但屬下列情形時,只用as, 而不用when或while。

  A) 用于表示同一個人的兩種動作交替進行,指"一邊……,一邊……"。如:

  The girl dances as she sings on the stage.

  He looked behind from time to time as he went forward.

  B)表示兩個同步發(fā)展的動作或行為,譯為"隨著……"。如:

  As time went on / by, she became more and more worried.

  As children get older, they become more and more interested in the things around them.

  C)表示兩個短促行為或事件幾乎同時發(fā)生。如:

  I thought of it just as you opened your mouth.

  Just as the flying worm hit her face, she gave a loud cry.

  D) 后接名詞表示某一年齡段時,用as。如:

  As a young man, he was active in sports.

  2. as=since, 作"既然"、"由于"解,引導原因狀語從句,常用來表示已為人們所知或顯而易見的原因或理由。如:

  As / Since you're not feeling well, you may stay at home.

  As he wasn't ready in time, we went without him.

  3. as=in the way that, 作"像"、"按照……的方式"解,引導方式狀語從句。如:

  He speaks English as Americans do.

  Remember, you must do everything as I do.

  4. 用于as...as...或not so/ as...as...中,前一個as是副詞,后一個as是連詞,引導比較狀語從句。如:

  They helped the old man as often as possible.

  I don't speak English so/ as well as he does.

  5. 作"雖然"、"盡管"解,引導讓步狀語從句。常用倒裝語序,即adj. /adv. / n.+ as +主語+謂語+主句。如:

  Tired as they were, they walked on.

  Child as he is, he knows a lot. (child前不用冠詞)

  二、 as作關系代詞,引導定語從句,作"正如"、"這一點"解。如:

  He is very careful, as his work shows.

  As is well-known, Taiwan belongs to China.

  另外,當先行詞被the same, such等詞修飾時,常用as來引導定語從句。如:

  Such a clever boy as he can learn anything quickly.

  I was reading the same book as he bought yesterday.

  三、 as作介詞的用法:

  as引導的介詞短語大多用作狀語,as譯為"作為";少數(shù)情況可引起賓語補足語。如:

  As a League member, I'll take the lead in everything. (狀語)

  She works as a doctor. (狀語)

  They have me as one of their own children.(引起賓語補足語)
