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，

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。

<1>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：

Marywashavingdinnerwhen

Isawher.

Theboywasstillsleeping

whenhismothergothomeyesterdaymorning.

<2>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:

Whilewewereswimmingsomeonestoleourclothes.

Don’ttalksoloudwhileothersareworking.Summary

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。3.统一时态：主句过去式，

从句也是过去式。ExercisesFillwith“While”or“When”1.____Maywastalkingonthephone,hersisterwalkedin.2.____Ritaboughthernewdog,itwaswearingalittlecoat.3._____IsawCarlos,hewaswearingagreenshirt.4._____Iwasdancing,hewassingingloudly.5._____LindafinallysawDavy,hewasjumpingwithadog.6.Iwascleaningmyroom________thefirebrokeout.WhenWhileWhileWhenWhenwhen
