Unit 5 What were you doing when the rainstorm came
单元语法专练
过去进行时
1.用法:过去进行时表示在过去某一时刻或某一段时间内正在进行的动作。
2.常用的时间状语:at that time/moment,(at) this time yesterday/last night/Sunday/last week...,at+时刻+yesterday/last night/Sunday...,when sb.did sth.等。例如:
I was doing my homework at this time yesterday.昨天的这个时候我正在做作业。
3.过去进行时的构成:
(1)肯定句:主语+was/were+doing+其他.
(2)否定句:主语+was/were+not+doing+其他.
(3)一般疑问句:Was/Were+主语+doing+其他?
简略回答:Yes,主语+was/were./No,主语+wasn’t/weren’t.
(4)特殊疑问句:疑问词+was/were+主语+doing+其他.
4.while和when的用法区别。
(1)引导时间状语从句时,when既可以连接时间点,又可以连接时间段;when既可以与延续性动词连用,又可以与非延续性动词连用。while连接时间段,与延续性动词连用。例如:
When my cousin came yesterday,I was playing volleyball.昨天我表哥来的时候,我在打排球。
I was drawing while my brother was reading.我弟弟在看书的时候,我在画画。
(2)while可以连接两个进行时态的句子,而when不可以。例如:
I was trying my best to finish my work while my sister was watching TV.我妹妹在看电视时,我正在努力完成工作。
(3)when用作并列连词时,when前的分句常用进行时态,when后的分句则用一般过去时,表示when前的分句动作发生的过程中,另一个意想不到的动作发生了。例如:
3
I was taking a walk when I met him.我正在散步,突然遇见了他。
