language practice
观察以上句子,是什么时态?
过去进行时
language focus
过去进行时
the Past Continuous Tense:
◆结构:
was / were + v.+ing
◆意义:
动词的过去进行时表示在过去某一时刻或某一时
间内正在进行或发生的动作。
◆时间状语:
at this/ that time yesterday, at 9pm last night, from… to… yesterday morning, when I came in (when引导的一般过去时态的句子)等等
过去进行时的句式结构
肯定句:主语 + was/were + 动词的现在分词 + 其他。
例如:I was reading a book at this time yesterday.
昨天这个时候我正在读一本书。
否定句:主语 + was/were + not + 动词的现在分词 + 其他。
例如:He was not watching TV last night.昨晚那个时候他没在看电视。
一般疑问句:Was/Were + 主语 + 动词的现在分词 + 其他?
例如:Were you playing football at 3 o'clock yesterday afternoon
昨天下午3点你在踢足球吗?
特殊疑问句:
特殊疑问词 + was/were + 主语 + 动词的现在分词 + 其他?
例如:What were you doing when I called you 我打电话给你时你在做什么?
一般过去时和过去进行时的区别
相同点:(the same)
不同点: (different)
     
两者都表示过去发生的动作。
一般过去时表示过去已完成的动作。
过去进行时表示过去正在进行的动作,可能没有完成。
例如:Laura was reading a novel at eight o'clock last night.
昨晚8点Laura在看小说。
Laura read a novel last night.
昨晚Laura看了一本小说。
过去进行时还可以和when,while, as引导的表示过去的时间状语从句连用,形成复合句。
请看例句:(1)One day, when Henry was working in a restaurant, a snake suddenly appeared.一天,当Henry正在餐馆里工作时,一条蛇突然出现了。
(2)While people were waiting for the traffic lights, a car suddenly appeared round the corner.就在人们等待红绿灯的时候,一辆汽车突然从拐角处驶出。
(3)As the doctors were checking him, the pain got worse.医生给他做检查时,疼痛加剧了。
下面,让我们来分析when和while引导的从句与过去进行时连用的几种情况。
when所引导的时间状语既可以指时间点,也可以指时间段;while所引导的时间状语只指时间段。因此,在when引导的时间状语从句中,动词可以是终止性动词,也可以是延续性动词:而在while引导的时间状语从句中,动词必须是延续性动词。
例如:They arrived while we were having dinner. 我们吃饭的时候他们到了。这句话还可以写成:They arrived when we were having dinner.
由when引导的时间状语从句,如果主句用过去进行时、从句用一般过去时,则表示一个动作正在进行的时候另一个动作(突然)发生了,强调后一动作发生的突然性。
例句:We were talking when the teacher came in.我们正在讲话,老师(突然)进来了。
该句也可以用while表达,但与用when表达有细微的区别,请注意体会:
While we were talking, the teacher came in.我们正在讲话的时候,老师进来了。(只表明老师进来的事实,不强调突然性)
当主句和从句的动作都是延续的或同时发生的,两句都用过去进行时的时候多用while引导。
例如:They were singing while we were dancing.
他们在唱歌,我们在跳舞。
过去进行时和 When 连用
A was/were +doing sth. When B +did sth.
长时动作
短时动作
过去进行时和 while 连用
A was/were +doing sth. While B + was/were +doing sth.
长时动作
长时动作
