B+was/were+doing

sth长时动作长时动作表示过去的状态、感觉及心理活动的静态动词(如be,like,love,hate,fear,own,hear,see,know,want,notice)可用于一般过去时，但通常不用于进行时。

eg:Ihateditwhenamanspokewithhismouthfulloffood.我讨厌人们说话时口里含着食物。一般过去时与always,constantly,forever,continually等连用，表示“过去经常性、习惯性的动作”；而过去进行时与always,constantly,forever,continually等连用，表示动作的重复，常带有感情色彩。eg:Healwayswenttobedatnine.他过去总是九点睡觉。Hewasalwaysthinkingofhiswork.他总是一心想到工作。不同点when引导的时间状语从句中，从句的动作和主句的动作可以同时发生，也可以一前一后先后发生；while则强调主句和从句的动作同时发生。有时when可以代替while，而while则不能代替when。_______wegottotheplaceoftheaccident,thecar______inbadshapefromhittingatree.Butluckily,thedriver_______fine.Theroads________icybecauseoftheheavysnowfromthenightbefore.Whenwaswaswere重点探究when和while引导时间状语从句Pairwork阅读教材上GrammarFocus中的句子，注意when和while所引导的状语从句的时态，同桌两人一组，说一说while和when句子中的动词的区别。Whatwereyoudoingateightlastnight?

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。Whatwereyoudoingatnineo’clocklastSundaymorningIwassleeping.HowaboutyouIwasdoingmyhomework.You’rekidding!Youmustbejoking!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：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:Whilewewereswimming,someo
