三、语法讲解

1．过去进行时

定义：过去进行时表示过去某一时刻或者某段时间正在进行或发生的动作，常和表过去的时间状语连用。如：at that time／moment, (at) this time yesterday (last night/Sunday/week...), at+点钟+yesterday(last night/Sunday.).

构成：

肯定形式：主语+was/were+v．-ing。

否定形式：主语+was not(wasn't)／were not(weren't)+v．-ing。

疑问形式：Was/Were+主语+v．-ing。

2．when，as和whil e的用法区别

(1)while只表示一段时间，while引导的时间状语从句中的动词必须是延续性动词，且主句的动作在从句动作的发生过程中发生或主从句两个动作同时发生。如：

He was talking to me while he was watching the TV. 他一边和我说话，一边看电视。

(2) when既可以表示具体的时间点，也可以表示一段时间，它所引导的从句的动作可以发生在主语动作之前，也可以是发生在后。当从句中都是延续性动作时，when与while可替换。如：

When I came into the room, I found him lying there asleep.

当我走进房间时，我发现他正躺在那儿睡觉。

(3) as多用于平行结构，表示两个动作同时发生，一个主语同时进行两个动作，一种状态随另一种状态的变化而变化。从句中多用表示动作的动词，而不用be动词或表示感觉、理解、知道这类动词。如：

As he stood there, he saw two men enter the bar.

当他站在那儿时，他看见两个人走进了酒吧。

(4)表示主句的动作发生在从句的较长动作过程中，when，while，as均可使用。从句中为be 动词时，多用when和while。谈论两个同时进行的长动作可用while，谈论两个平行动作或两种状态变化多用as。
