行时强调动作正在进行，而一般过去时则表示过去某一时间所发生的动作或存在的状态，它表示的动作往往已经完成。“在”说明正在进行，而“I read a story book yesterday evening.”的意思是昨晚我读了一本故事书，言下之意已经读完了。故用过去进过去进行时主要表示过去某一时刻正在进行的动作，或表示过去某一阶段一直在进行的动作。一起和小编来看一下过去进行时的易错题吧！    　一、丢掉be动词或忘记把动词变成现在分词 　　例：1 I watching (watch) TV when he came in. 　　2 They were play (play) games at 5:00 p.m. yesterday. 　　答案：1 was watching 2 were playing 　　解析：现在进行时中“be+现在分词,缺一不可”的规律也可应用于过去进行时。 　　二、对动词或动词词组提问时丢掉doing 　　例：We were flying kites at 5:00 p.m. yesterday. (对划线部分提问) 　　What were you at 5:00 p.m. yesterday? 　　答案：What were you doing at 5:00 p.m. yesterday? 　　解析：现在进行时中“What……doing……”?句式同样适用于过去进行时。 　   三、易把be+现在分词记成be+过去分词 　　例：He was talked (talk) to his mum at that time. 　　答案：was talking 　　解析：过去进行时与现在进行时结构上的区别体现在be动词上。　       四、易与现在进行时弄混 　　例：My mother is cooking (cook)when I got home. 　　答案：was cooking 　　解析：这两种时态的共同点是都表示动作正在进行，但现在进行时前提是现在，而过去进行时前提是过去，由when I got home可看出前提是过去。 　　五、易与一般过去时弄混 　　例：昨晚我在读一本故事书。 　　I read (read) a story book yesterday evening. 　　答案：was reading 　　解析：这两种时态的共同点是都用于表示过去发生的动作。但过去进行时强调动作正在进行，而一般过去时则表示过去某一时间所发生的动作或存在的状态，它表示的动作往往已经完成。“在”说明正在进行，而“I read a story book yesterday evening.”的意思是昨晚我读了一本故事书，言下之意已经读完了。故用过去进行时。 　　另外，在宾语从句中当主句为过去时，从句若是现在进行时，需变成过去进行时。 　　e.g. He said that he was drawing a cat at noon yesterday. 看完以后同学们是否对过去进行时有了更全面的了解呢？语法是一块难啃的硬骨头，但只要每天消化一点点，拿下它便指日可待。

过去进行时是英语中一个重要的时态，今天 ，小编为大家收集、整过去进行时是英语中一个重要的时态，今天 ，小编为大家收集、整理了若干有关英语过去进行时的练习题，大家可以自行测试一下哦！   一、用括号内所给动词的正确形式填空 1. I , with my sister , sometimes ______ swimming in the river. (go) 2. He __________ the film with us last night. (not see) 3. You draw quite well. I think you _______ a good painter in the future. (be) 4. One Sunday

过去进行时表示按计划、打算 During that time he was going with us.（表示打算） 3、与always ，often ，usually 等连用表喜爱，讨厌等感情色彩。 He was always Changing his mind. 三、过去进行时与一般过去时的区别 1、进行时表某一行为的“片断”一般时表示行为的“整体”和存在的状态。 I was reading the book at that time. （未读完，“读”的片段） I read the book yesterday. （已读完，表整个“读”） 2、一般持续时间状语多与进行时连用 It was raining all night.（优过去进行时和一般过去时的区别： 一、过去进行时和一般过去时的区别在于：一般过去时叙述旧事，过去进行时先用was raining ，rained 为持续动词，故也可使用） He was writing a letter the whole of afternoon. （短暂动词与持续时间连用，表反复，连续发生，不可用一般过去时）  

　过去进过去进行时由 was/were 加现在分词构成。 　　例如： 　　What were you doing this time yesterday?昨天这个时候你在做什么? 　　During the summer of 1999 she was travelling in Europe.1999年夏天她在欧洲旅行。 　　He said he was leaving for home in a day or two. 他说他一两天之内就动身回家了。 　　She was always thinking of others. 她老是想到别人。(赞扬) 　　She was forever complaining. 她老是抱怨。(厌烦) 　　I was reading the newspaper when the doorbell rang. 我正在看报，突然门铃响了。 　　Jim burnt his hand when he was cooking the dinner. 吉姆做饭时把手烫了。 　　I met Diana while I was shopping this morning. 我今早买东西时碰到了戴安娜。 　　I was doing my homework while he was listening to music. 我在做作业而他在听音乐。

和他妹妹在一起。 2.If i had enough money,i would be traveling for seven days. 如果我有很多钱，我会旅游七天。 3.If i had enough money,i would be going to e beijing is the capital city of china. 如果我有很多钱，我会去北京，因为北京是中国的首都。 4.If i had enough money,i would be going to qingdao with my friends. 如果我有很多钱，我会和我的朋友们去青岛。 二、过去将来进行时表示在过去将来某一时间正在发生的动作，它常和表过去将来的时间状语连用，但上下文清楚时，时间状语亦可省略。和将来进行时一样，它也常表计划中的事，不表意愿或打算。它过去将来进行时可以表示在过去某一时间之后即将进行还有一个特点，即常用在宾语从句(尤其是间接引语)中。例如： 1.John told us that Mary would be going to Tianjin next

能来因为要开会。 5.He asked me where i would be going at six the next day. 他问我次日六点将去哪里。 6.The new job he would be taking was translating the English books. 他将要接受的新过去将来进行时的基本结构是：“主语+should(would)+be+现在分词”或者“was/were going to + 动词原形”构成。过去将来进行时工作是翻译英文书。 7.He said that he could not come because he would be going to hospital for an emergency . 他说他不能来因为他有紧急事情去医院。 8.They said they would be reading Shakespeare next Monday. 他们说了他们将在下周一读莎士比亚。 9.On May 18, the employee wrote to the council that he would be taking the doctor’s advice. 5月18日，这位雇员致信委员会，称他将遵照医嘱。

行时的用法 A. 在某段时间内一直进行的动作用现在完成进行时来强调动作在某段时间里的持续性动作通常有"现在"的结果要根据上下文来确定到"现在"为止动作是否还在继续进行同样过去完成进行时表示在过去更早时间内进行的动作,并对过去某一时刻产生结果。 B.表示重复动作的现在/过去完成进行时 我们也可以用完成进过去完成时代替，例如： He had not practiced English for many years 他没有练习英语很多年了。（普通说法） He had not been practicing English for many years. 很多年了，他一直没有练习英语。（少见） 二、这种时态还可用在said，supposed等引起的间接引语中代替现在完成进行时 He said“I have been speaking to John”= He said that he had been speaking to John 他说“我一直和约翰说着话”。 He thought“She was watching me when I passed”= He thought that she had been watching him when he had passed 他想“当我经过的时候，她正看着我”。 三、过去完成进行时经常与现在完成进行时混淆。 现在完成进行时 (The present perfect progressive) 由 have/has been +-分词构成 过去完成进行时 The past perfect progressive tenses 由 had been +-分词构成 四、现在/过去完成进行时的用法 A. 在某段时间内一直进行的动作用现在完成进行时来强调动作在某段时间里的持续性动作通常有"现在"的结果要根据上下文来确定到"现在"为止动作是否还在继续进行同样过去完成进行时表示在过去更早时间内进行的动作,并对过去某一时刻产生结果。 B.表示重复动作的现在/过去完成进行时 我们也可以用完成进行时形式来表示现在或过去经常重复的动作。 注意过去完成进行时和过去完成时类似需要有过去这一时间点。

行时主要表示过去某时的一个动作正在进行。例如： 1. I was writing a letter when she came to see me. 当她来看我时我正在写信。 2.I had been writing a letter for two hours by the time she came to see me. 当她来看我的时候，我已经写了两个小时的信了。 5. 过去完成进过去完成进行时是一种比较抽象的时态，学习它需要理解整个句子所处的语境和时间。过去完成进行时行时与过去完成时的不同。过去完成时表示过去某时间前已经发生的动作或情况，这个过去的时间可以用by，before等介词短语或一个时间状语从句来表示；或者表示一个动作在另一个过去动作之前已经完成。例如： 1. They had just had breakfast when Tom came in. 汤姆来时，他们刚吃过早饭。 2. They had been having breakfast for ten minutes when Tom came in. 汤姆来时，他们已经吃了十分钟的早饭了。

行时的被动态。基本形式：should/would have been being done. 请看例句： 1. He said the trees would have been being planted on March 12th on the mountain this year by the students, because the school had already decided. 他说今年3月12日会有很多树苗被学生种下，因为学校已经决定这项活动了。 2. She said that by the end of last weekend, the book would have been being read for 2 weeks. 她说直到上周末，这本书就已经被读了两周了。 3. This topic would have been being considered for a month. 这个话题已经被考虑了1个月了。 4. Tom's room would have been being cleaned. 汤姆的房间会被打扫。 5. The play would have been being performed for 2 hours. 这场表演会持续两小时。 6. Up to that time those books had been being translated. 直到那时，这些书还在被翻译。 7. The letter had been being written till two o'clock. 写这封信写到了2点。 由基本形式转过去将来完成进行时，表示动作从过去某时间开始一直延续到对于过去换为被动态还是挺简单的，不过这里需要注意的是被动态的形式为should/would have been being done。请不要和过去将来完成时的被动态would + have + been + done混淆。前者为持续性动作，而后者并无持续性的意思。
