Unit 5 What were you doing when the rainstorm came?
过去进行时
(时间:60分钟,满分:100分)
一、过去进行时的结构
过去进行时句子中的谓语部分由“was/were+现在分词”构成。
过去进行时谓语部分的否定式由“was/were not+现在分词”构成。
过去进行时的一般疑问句由“Was/Were+主语+现在分词?”构成。
二、时间状语
常用来表示过去进行时的时间状语有at nine o'clock yesterday,from nine to ten last evening,at that time等。
三、过去进行时表示的感情色彩与现在进行时相似,过去进行时也可表示满意、称赞、惊讶、厌恶等感情色彩,也通常与 always,forever等副词连用。
eg:They were always speaking. 他们老是说话。
四、需注意部分动词是不用于进行时的
(1)感官动词:hear,see,feel,taste...
(2)表示爱憎的动词:like,love,hate...
(3)表希望、意愿的动词:want,wish...
(4)表占有的动词:own,have...
(5)其他动词:appear,be...
过去进行时还可以和when,while,as引导的过去时间状语从句连用。
when, while和as 引导的时间状语从句都可以使用延续性动词,when,as也可以与短暂性动词连用,而while则不能。
例:(1)I was doing my homework when my mother got home last night.昨晚当我妈妈回家时,我正在做作业。(got home是短暂性动作)
(2)They called me when I was having dinner.当我正在吃晚饭时,他们给我打电话了。(was having dinner是延续性动作)
(3)While he was riding his bike,a car hit him suddenly.当他正在骑自行车时,突然一辆小汽车撞了他。(was riding是延续性动作)
(4)As I was walking one day in Hyde Park,I noticed two elderly ladies.有一天,当我在海德公园散步的时候,我看到了两位老年妇女。(was walking 是延续性动作)
when可表示瞬间,也可表示时间段,表示从句与主句所陈述的动作、事情可以同时发生,也可有先后。若主句为过去进行时,从句为一般过去时,则表示一个动作正在进行的时候,另一个动作(突然)发生了,强调后一动作的突然性。
eg:I was doing my homework when my mother came back home last night.昨晚当我妈妈回家时,我正在做作业。
while用于同时进行的两个延续性动作相伴随而发生,常对同类的两个动作进行比较。
eg:My mother was cooking while my father was watching TV.我妈妈正在做饭,(与此同时)我爸爸正在看电视。
