The boy was still sleeping when his mother got home yesterday morning .,while表示“在的时候”、“在期间”。 它强调主句的动作与从句的动作同时发生或 主句的动作发生在从句的动作过程中。While 从句中必须是表示动作或状态的延续性动词。如： The weather was fine while we were in Beijing . She called while I was out. 如果主句的动作在从句的动作过程中发生， 从句常用进行时。如: While we were swimming someone stole our clothes . Dont talk so loud while others are working.,总结,1) when可指时间点, 又可指时间段, 从句中 可用延续性动词, 也可用非延续性动词。 2) while总是指一个时间段, 从句中必须用延 续性动词。,1. _ Jennifer was reading a magazine, his sister was listening to the pop music.
