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、die等。(2)在本单元中,出现了由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。从句中的动作既可以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。e.g.MarywashavingdinnerwhenIsawher.

Theboywasstillsleepingwhenhismothergothomeyesterdaymorning.语法聚焦由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从句中必须用表示动作或状态的延续性动词。e.g.

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。e.g.Whilewewereswimming,someonestoleourclothes.Don’ttalksoloudlywhileothersareworking.【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。语法聚焦John

外面没有光亮，感觉就像半夜一样。此句中介词with表示一种伴随的状况，同时还包含着某种因果关系，表示“因某种状况的存在而导致……”，因此可译作“由于；因为”等。e.g.Ican’tworkwithallthatnoisegoingon.由于那噪音响着，我无法工作。Languagepoints2.Ben’sdad...whilehismomwasmakingsuretheflashlightsandradiowereworking.在他妈妈确认手电筒和收音机都能正常使用的同时，本的爸爸……(1)此句中的连词while的意思是“当……的时候；和……同时”，while还可以表示“然而；但（是）”之意，用来说明或强调两种事情或情形的不同。e.g.TomisactiveandoutgoingwhilehissisterRosaisshyandquiet.

汤姆活跃外向,而他的妹妹罗莎却羞怯腼腆。
