1. 以when和while引导的时间状语从句
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, 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：
Mary was having dinner when I saw her.
The boy was still sleeping when his mother got
home yesterday morning.
3)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：
The weather was fine while we were in Beijing.
She called while I was out.
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:此处缺少例子
