一、 概念和用法:过去进行时表示在过去某一时刻或某一段时间内进行或发生的动作。其形式为was /were + V-ing。常与表示过去的时间状语连用,如:last night, last Saturday等;或者与when, while, as引导的过去时间状语连用。例如: We were watching TV from seven to nine last night. 昨天晚上七点到九点的时候我们在看电视。 What was he researching all day last Sunday? 上周日他一整天都在研究什么? 二、 过去进行时可以表示在过去某个时间点发生的事情。时间点可以用介词短语、副词或从句来表示。如: What was she doing at nine o'clock yesterday? 昨天晚上九点她在做什么? (介词短语表示时间点) When I saw him he was decorating his room. 当我看见他的时候他正在装饰房间。 (when从句表示时间点) 三、 在复合句中,如果主要动作和背景动作都是延续的或同时发生的,那么主从句的动词都可用过去进行时。例如: While he was waiting for the bus, he was reading a newspaper.他边等车边看报。 (两个动作都是延续的) He was cleaning his car while I was cooking. 他擦车时我在做饭。(两个动作同时进行) 四、 通常不能用于过去进行时的动词主要有:agree, be, believe, belong, care, forget, hate, have(拥有), hear, know, like, love, mean, mind, notice, own, remember, seem, suppose, understand, want, wish等。例如: 误:I was knowing the answer. 正:I knew the answer. 我知道答案。 误:I wasn't understanding him. 正:I didn't understand him. 我不明白他的意思。 (文/朱孔仁;英语辅导报初四普及版04—05学年度第7期;版权归英语辅导报社所有,独家网络合作伙伴新浪教育,未经许可,不得以任何形式进行转载。) |
