when表示前面的叙述所没有提到过的信息。它总是对所描述的事件予以引人注目的强调,意为“这时;突然”;当位于句末的分句具有引种用法时,大致有以下三种情况:
A. when 分句前面的分句使用过去进行时。
如: ( 1 ) He was still smiling when the door opened and his wife came in. 他正笑着的时候,门突然开了,他妻子走了进来。
( 2 ) I was thinking of this when I heard my name called. 我正想着这件事时,突然听到有人叫我的名字。
B. when 分句前面的分句使用 was (were) about to, was (were) on the point 等。
如: ( 1 ) We were about to start when it began to rain. 我们刚要出发就开始下雨了。
( 2 ) He was on the point of leaving when someone knocked at the door. 他刚要走就有人敲门。
C. when 分句之前的分句用过去完成时,其中 sb had hardly / scarcely /barely … when 已成为固定词组。如:
( 1 ) We had hardly fallen asleep when the bell rang. 我们刚刚入睡,铃声就响了起来。
( 2 ) He had scarcely arrived when he had to leave again. 他刚刚到达就又要离开了。
