Grammar过去进行时的基本用法①表示过去某一段时间内一直进行的动作，常与thewholeday、

Grammar过去进行时和一般过去式的区别①

过去进行时表示过去某一时刻或某一段时间正在进行的动作，而一般过去时则表示在过去某个时间发生过的动作或存在的状态。e.g.Hewasplayingbasketballatthreeyesterdayafternoon.

昨天下午三点他正在打篮球。

（强调昨天下午三点正在进行的动作，不一定结束）Heplayedbasketballyesterdayaftemoon.昨天下午他打篮球了。

（强调昨天下午打篮球的动作已经结束）

Grammar过去进行时和一般过去式的区别②

Let’sthink试着总结when和while的用法区别Whatwereyoudoingwhileitwassnowingheavily?Iwastravellingonthetrainthen.Whatwereyourfamilydoingwhenthetyphoonhit?MychildrenandIwerereadingtogether.Whenmyneighbourcalled,myfamilywerehavingdinner.Weweredrivinghomewhenthestrongwindsstarted.Whileweweredrivinghome,thestrongwindsstarted.Itwasraininghardwhileweweredrivingback.snow延续性动词hit短暂性动词call短暂性动词start短暂性动词drive延续性动词drive延续性动词

语法知识导图when和while引导的时间状语从句when引导的时间状语从句(二)when和while引导的时间状语从句→从句的谓语动词必须是延续性动词，

且常用进行时主从句的动作可以同时发生，也可以先后发生while引导的时间状语从句从句中的谓语动词可以是延续性动词，也可以是非延续性动词遵循“主将从现”的原则

when和while引导的时间状语从句Grammarwhen和while都可意为“当······时”，用来引导时间状语从句，表示主句动作发生的背景。从句可位于主句之前或之后，当位于主句之前时，与主句要用逗号分开。辨析：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。run“跑”延续性动词fall“跌倒”非延续性动词（瞬间动词）

Grammarwhen引导的时间状语从句①表示主句动作发生的特定时间，既可指时间点，也可指时间段。e.g.Callmewhenyougethome.你到家时给我打个电话。Whenhewasachild,healwaystriedoutnewideas.

他小的时候总是在试验一些新设想。②when引导的时间状语从句中的谓语动词可用延续性动词，也可用

非延续性动词。从句的动作可与主句的动作同时发生，也可在主句

动作之前或之后发生。e.g.Thephonerangwhenhewasreading.他看书时电话响了。

（rang和wasreading同时发生）

Grammarwhen引导的时间状语从句②when引导的时间状语从句中的谓语动词可用延续性动词，也可用

非延续性动词。从句的动作可与主句的动作同时发生，也可在主句

动作之前或之后发生e.g.WhenIgottotheshop,thedoorwasclosed.

当我赶到商店时，店门已经关上了。（gotto后发生）Whentheyfinishedtheirhomework,theyhelpeddothehousework.

他们完成家庭作业后，帮忙做了家务。（finished先发生）③当主句为将来时或表示将来的意义时，从句要用一般现在时表示

将来，即遵循“主将从现”的原则。e.g.Theboywillbeawriterwhenhegrowsup.

这个男孩长大后会成为一名作家。

Grammarwhile引导的时间状语从句while引导时间状语从句时，从句的谓语动词必须为延续性动词，且常用进行时。常见情况有：①

强调主句动作发生时，从句动作正在进行，此时，从句用进行时。e.g.WhileIwaswaitingforthebus,Imetmyteacher.

当我在等公共汽车时，我遇见了我的老师。②

强调主从句动作同时进行时，主从句通常都用进行时。e.g.Whilemymotherwascookingdinner,Iwasplayingchesswithmybrother.

我妈妈做晚饭的时候，我和弟弟在下国际象棋。
