When I was cooking dinner, he arrived. 当我正在做晚饭时,他到了。 当他到时,我正在做晚饭。 重点是复合句 ,即有两个主谓结构的句子。对比此句中的两个动作,延续性动作用过进,短暂瞬间性动作用一过,注意第一要义是判断动作确定时态。“当”引导的是从句 31 Examples 分析: 1.此时时间状语从句用过去进行时,引导正在进行的延续性的动作; 2.主句用一般过去时,引导突然发生的短暂性的动作。 例1:当我在听音乐时,我妈妈进来了。 When I was listening to music, my mother came in. 32 Examples 例2:当我扫地的时候,发现了你的钢笔。 分析: 扫地:从句 正在进行的延续性动作 过去进行时 (sweeping the floor) 发现笔:主句 突然发生的短暂性动作 一般过去时 ( found your pen) When I was sweeping the floor, I found your pen.
