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）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。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?

答语：Yes,主语+was/were.

或No,主语+wasn't/weren’t.4.特殊疑问句：疑问词+was/were+主语+doingWhatwereyoudoingatthetimeofrainstorm?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：MarywashavingdinnerwhenIsawher.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,someonestoleourclothes.Don’ttalksoloudwhileothersareworking.1.V-ing的构成1)一般动词在词尾加-ing,读[iη],

如go–going。2)以不发音字母e结尾的动词,先去掉e,再加-ing。

come-coming

make-making

write-writing3)以重读闭音节结尾的动词,如果末尾以一个辅音字母结尾,应先双写这个字母,再加ing,x和w结尾的除外。如:get-getting

swim-swimming

box–boxing4)以字母y结尾的单词,直接加ing。

如:carrying,playing,studyingPractice
