  新东方在线中考网整理了《2019中考英语复习资料as, when, while》,供同学们参考。

  as, when, while

  这三个连词都可引导时间状语从句,但用法有所不同。

  1) 当某事正在进行的时候,又发生了另一件事。While, when, as 都可用来引导表示“背景”的时间状语从句。例如:

  As/When/While I was walking down the street I noticed a police car.

  2) 当两个长动作同时进行的时候,最常用的是while。例如:

  While mother was cooking lunch, I was doing my homework.

  3) 当两个动作都表示发展变化的情况时,最常用的是as。例如:

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

  4) 当两个短动作同时发生时,或表示“一边…一边…”时,最常用as。例如:

  Just as he caught the fly, he gave a loud cry.

  She looked behind from time to time as she went

  5) 当从句的动作先于主句的动作时,通常用when。例如:

  When he finished his work, he took a short rest.

  6) 当从句是瞬间动作,主句是延续性动作时,通常用when。例如:

  When John arrived I was cooking lunch.
