【动作动词的分类与用法】
• 1. 表示持续动作的动词，如 eat, listen, read, run等。例如： She is listening to the radio. 她在听收音机。 2. 表示短暂动作的动词，如 hit, jump等。这类动词一般用 在现在时中，表示现时的一次性动作。表示短暂动作的动 词通常不用于进行时态中，如果用于进行时的话，那就表 示短暂动作的多次重复。例如： She jumped up into the chair. 她跳起来坐到椅子上。 He was jumping up and down to keep warm. 他上下跳动来 取暖。 3. 表示转变和移动的动词，如arrive, change, come, die, go, leave等。这类动词用于一般时和进行时中，往往在意义 上略有不同。比如说The train leaves at nine，这是一种现 在的习惯性动作，表示火车每天都是9点开车。如果说 The train is leaving，则表示即将发生的事态，表示火车马 上就要开了。

Activity verb ＆ State verbs 动作动词 和 状态动词
英语中的动词就其词汇意义来说可分为动作动词（Activity verb） 和状态动词（State verb）。动作动词强调主语在做的动作，而 状态动词强调主语所处的状态，状态动词通常不用于进行时。 例如： The girl is putting on a red coat. 那个女孩正在穿一件红色外套。 （穿的动作正在发生，put为动作动词）。 We have a second-hand car. 我们有一辆二手车。（have为状 态动词）。
We use the present continuous
1) to talk about temporary situations: I’m studying really hard for my exams. My cousin is living in Thailand at the moment.(=he doesn’t normally live there)
3) to talk about facts or generally accepted truths Students don’t generally have much money. If you heat water to 100℃, it boils.
4) to give instructions and directions: You go down to the traffic lights, then you turn left. To start the programme, first you click on the icon on the desktop.
5) to tell stories and talk about films, books and plays: In the film, the tea lady falls in love with the Prime Minister.
