过去进行时用法及练习题2.doc

　一、过去进行时的概念：
　　过去进行时表示过去某一时刻或过去某一阶段时间正在进行的动作。　　　What were you doing this time yesterday? I was playing basketball．What were you doing those days? I was reading a storybook．
　　二、过去进行时的构成：
　　过去进行时由助动词be的过去式were(was)加doing构成。如：她/他们在放风筝：She/was( They were)flying a kite(kites).
　　三、过去进行时的句式
　　(1)陈述句的肯定形式：主语+were(was)+doing…．如：
　　He was doing his homework then．
　　(2)陈述句的否定形式：主语+were(was)+not doing…．如：
　　I was not doing my homework then．
　　Were(was)not还可缩写成weren’t或wasn’t。
　　(3)一般疑问句的肯定、否定及其回答：
　　Were(was)+主语+doing…？
　　Yes, 主语(人称代词)were(was)．
　　No, 主语(人称代词)weren’t(wasn’t)．
　　如：Were they doing their homework then?
　　Yes, they were．/No, they weren’t．
　　过去进行时与现在进行时的区别：
　　两者都表示动作正在进行，只是时间有别。现在进行时表示现在或现阶段正在进行的动作。过去进行时则表示在过去的某一时间点或过去某一阶段正在进行的动作。如：
　　瞧！他们在踢足球。
　　Look! They are playing football．
　　上星期六这个时间，他们也在踢足球。
　　They were playing football this time last Saturday, too．
　　这几天我在学骑自行车。
　　I am learning to ride a bike these days．
　　上星期我在学骑自行车。
　　I was learning to ride a bike last week．
　　过去进行时的用法
　　(1) 过去进行时表示过去某一时间正在进行的动作，常和表过去的时间状语连用 ，如； 昨天的这个时候我正在做作业。
　　I was doing my homework at this time yesterday.
　　他们昨天一直在等待。
　　They were expecting you yesterday.
　　(2) 过去进行时可与 soon, the next moment, in... minutes, ...minutes later 等时间状语连用，表示一个新的动作刚刚开始。 如：
　　Soon the whole town was talking about it. 不久镇上的人就都谈论起这种事了。
　　(3) 过去进行时可用来申述原因或用作借口，这种用法常用在口语中。 如：
　　-- Have you finished your homework, Mary? 玛丽，你作业做完了吗？
　　-- No, I was helping my mother in the kitchen all day yesterday.
　　　　还没呢，我昨天一天都帮妈妈在厨房干活。
　　(4)过去进行时可用来为后面一系列动作的发生提供背景。 如：
　　I hurt my leg when I was riding a bike. 我在骑车时把腿摔坏了。
　　(5) 过去进行时可表示过去未曾实现的愿望或打算，这时 be 动词 was/were 要重读 。如：
I was writing him a letter this morning and forgot all about it . 我本该今天早上给他写信的，后来全给忘了。
　　I was seeing her tomorrow.　我本来打算明天会见她。
　　He was watching the play yesterday, but he was too busy. 他昨天 本来要看那场戏的，可是太忙了。
　　(6)由when 和 while 引导的状语从句，强调某个动作正在进行的过程中时要用进行时态， while 表示一段时间，因此，在它所引导的状语从句中，谓语动词常用进行时态，如：
　　When/While we were having supper, the light went out. 我们正在吃饭时灯熄灭了。
　　when 用作并列连词时，主句常用进行时态，从句则用一般过去时，表示主句动作发生的过程中，另一个意想不到的动作发生了。如：
　　I was walking in the street when someone called me. 我正在街上走时突然有人喊我。
　　6. 下面几种情况不用一般过去时而要用过去进行时：
　　(1)表示过去某一阶段暂时性的习惯动作时。如：
　　Tom was getting up at six o ' clock every day that week. 汤姆那一周里每天都是六点钟起床。
　　(2)与 always 连用表示赞美，厌烦等感情色彩时。如：
　　John was always coming to school late. 约翰上学总是迟到。
　　Lei Feng was always doing good deeds for the people. 雷锋总是为人民做好事。
　　(3)用来描写故事发生的情景时。如：
　　It was a dark night. The wind was blowing hard and the rain was falling heavily. A PLA man suddenly appeared on the river bank. He wanted to cross the river. 那是一个漆黑的夜晚，风刮得很厉害，雨下得很大，一个解放军战士突然出现在河岸上，他想过河去。
　　(4) when 作并列连词，表示 “ (这时)突然 ” 之意时，第一个并列分句用过去进行时， when 引导的并列分句用一般过去时。如：
　　我正在散步，突然遇见了他。
　　I was taking a walk when I met him.
　　我们正在外边玩，这时下起雨来了。
　　We were playing outside when it began to rain.
　　(5 )go, come, leave, start, arrive 等动词可用过去进行时表示过去将来的含义。如：
I was leaving for Wu han that day. 那天我正要去武汉。
