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。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。MarywashavingdinnerwhenIsawher.

Theboywasstillsleepingwhenhismothergothomeyesterdaymorning.当我看到Mary的时候她正在吃饭。当他妈妈昨天早上到家的时候，这个男孩仍然在睡觉。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：当我们在北京的时候天气很好。在我出去的那段时间里她打电话来了。TheweatherwasfinewhilewewereinBeijing.ShecalledwhileIwasout.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:当我们在游泳的时候，一个人偷走了我们的衣服。当其他人在工作的时候不要这么大声说话。Whilewewereswimming,someonestoleourclothes.Don’ttalksoloudwhileothersareworking.Fillintheblankswithwas,were,whenorwhile.4bAt7:00a.m.,Iwokeup._____I____makingmybreakfast,mybrother_____listeningtotheradio._____Iwaseating,theradionewstalkedaboutacaraccidentnearourhome.MybrotherandIwentoutrightawaytohavealook._____wegottotheplaceoftheaccident,thecar____inbadshapefromhittingatree.Butluckily,thedriver____fine.Theroads_____icybecauseoftheheavysnowfromthenightbefore.WhilewaswasWhileWhenwaswaswere4c.WhatwereyoudoingatthesetimeslastSunday?Fillinthechart.Thenaskyourpartner.A:Whatwereyoudoingatnineo’clocklastSundaymorning?B:Iwassleeping.Howaboutyou?A:Iwasdoingmyhomework.B:You'rekidding!Ⅱ.根据各题后括号内的要求完成下列各题，每空一词（含缩略形式）。1.Iwasrunningintheparkat7:00yesterdaymorning.
