friends last night.他们昨晚写了信给他们的朋友。（表达了他们已写好的意思，整个写的过程已完成。）,5.以when和while引导的时间状语从句,1）延续性动词和非延续性动词延续性动词指动作可以延续一段时间，而不是瞬间结束。如：work、study、drink、eat等。非延续性动词指动作极为短暂，瞬间结束。如：start、begin、hit、jump、knock等。,5.以when和while引导的时间状语从句,2）在本单元中，出现了以when和while引导的时间状语从句。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.,5.以when和while引导的时间状语从句,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。,课堂练习,一.翻译下列短语或词组1.在前面 _ 2.理发店 _3.睡懒觉 _ 4.从出去 _5.打电话给警察 _ 6.跳下来 _,课堂练习,一.翻译下列短语或词组7.run away _ 8.in hospital _9.at the
