She was working at a radio shop at that time.我第一次遇到玛丽是在三年前，当时她在一家无线电商店工作。I was cooking when she knocked at the door.她敲门时我正在做饭。2. when后通常用表示暂短性动词，while后通常用表示持续性动词，因此它所引导的状语从句中，谓语动词常用进行时态，如：When the car exploded I was walking past it.= While I was walking past the car it exploded.3. 在本单元中，出现了以when和while引导的时间状语从句。 （1） when表示“当的时候”。从句中既可用延续性动词，又可用非延续性动词，这些动词既可以表示动作，又可表示状态。从句中的动作既可和主句的动作同时发生，又可在主句的动作之前或之后发生。如：Mary was having dinner when I saw her. The boy was still sleeping when his mother got home yesterday morning （2） 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.4. 分句用一般过去时。如：I was taking a walk when I met him.我正在散步，突然遇见了他。 We were playing outside when it began to rain.我们正在外边玩，这时下起雨来了。 B. 语言点1.
