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

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

  Work while you work.Play while you play.

  ③但属下列情形时,只用as,而不用when或while。

  a.用于表示同一个人的两个动作交替进行,指“一边……,一边……”。

  They helped the old man as often as possible.

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

  (5)作“虽然”“尽管”解,引导让步状语从句。常用倒装语序,即adj./adv./n.+as +主语+谓语+主句。

  Tired as they were,they walked on.Child as he is,he knows a lot.(child前不用冠词)

  as作关系代词

  (1)引导非限制性定语从句,作“正如”“这一点”解。

  He is very careful,as his work shows.

  As is well­known,Taiwan belongs to China.

  as的这种用法,请看下面的高考题:
