行時強調動作正在進行，而一般過去時則表示過去某一時間所發(fā)生的動作或存在的狀態(tài)，它表示的動作往往已經(jīng)完成?！霸凇闭f明正在進行，而“I read a story book yesterday evening.”的意思是昨晚我讀了一本故事書，言下之意已經(jīng)讀完了。故用過去進過去進行時主要表示過去某一時刻正在進行的動作，或表示過去某一階段一直在進行的動作。一起和小編來看一下過去進行時的易錯題吧！ ?? 　一、丟掉be動詞或忘記把動詞變成現(xiàn)在分詞 　　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：現(xiàn)在進行時中“be+現(xiàn)在分詞,缺一不可”的規(guī)律也可應用于過去進行時。 　　二、對動詞或動詞詞組提問時丟掉doing 　　例：We were flying kites at 5:00 p.m. yesterday. (對劃線部分提問) 　　What were you at 5:00 p.m. yesterday? 　　答案：What were you doing at 5:00 p.m. yesterday? 　　解析：現(xiàn)在進行時中“What……doing……”?句式同樣適用于過去進行時。 　?? 三、易把be+現(xiàn)在分詞記成be+過去分詞 　　例：He was talked (talk) to his mum at that time. 　　答案：was talking 　　解析：過去進行時與現(xiàn)在進行時結構上的區(qū)別體現(xiàn)在be動詞上?！?????? 四、易與現(xiàn)在進行時弄混 　　例：My mother is cooking (cook)when I got home. 　　答案：was cooking 　　解析：這兩種時態(tài)的共同點是都表示動作正在進行，但現(xiàn)在進行時前提是現(xiàn)在，而過去進行時前提是過去，由when I got home可看出前提是過去。 　　五、易與一般過去時弄混 　　例：昨晚我在讀一本故事書。 　　I read (read) a story book yesterday evening. 　　答案：was reading 　　解析：這兩種時態(tài)的共同點是都用于表示過去發(fā)生的動作。但過去進行時強調動作正在進行，而一般過去時則表示過去某一時間所發(fā)生的動作或存在的狀態(tài)，它表示的動作往往已經(jīng)完成?！霸凇闭f明正在進行，而“I read a story book yesterday evening.”的意思是昨晚我讀了一本故事書，言下之意已經(jīng)讀完了。故用過去進行時。 　　另外，在賓語從句中當主句為過去時，從句若是現(xiàn)在進行時，需變成過去進行時。 　　e.g. He said that he was drawing a cat at noon yesterday. 看完以后同學們是否對過去進行時有了更全面的了解呢？語法是一塊難啃的硬骨頭，但只要每天消化一點點，拿下它便指日可待。

過去進行時是英語中一個重要的時態(tài)，今天 ，小編為大家收集、整過去進行時是英語中一個重要的時態(tài)，今天 ，小編為大家收集、整理了若干有關英語過去進行時的練習題，大家可以自行測試一下哦！ ? 一、用括號內所給動詞的正確形式填空 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

過去進行時表示按計劃、打算 During that time he was going with us.（表示打算） 3、與always ，often ，usually 等連用表喜愛，討厭等感情色彩。 He was always Changing his mind. 三、過去進行時與一般過去時的區(qū)別 1、進行時表某一行為的“片斷”一般時表示行為的“整體”和存在的狀態(tài)。 I was reading the book at that time. （未讀完，“讀”的片段） I read the book yesterday. （已讀完，表整個“讀”） 2、一般持續(xù)時間狀語多與進行時連用 It was raining all night.（優(yōu)過去進行時和一般過去時的區(qū)別： 一、過去進行時和一般過去時的區(qū)別在于：一般過去時敘述舊事，過去進行時先用was raining ，rained 為持續(xù)動詞，故也可使用） He was writing a letter the whole of afternoon. （短暫動詞與持續(xù)時間連用，表反復，連續(xù)發(fā)生，不可用一般過去時） ?

和他妹妹在一起。 2.If i had enough money,i would be traveling for seven days. 如果我有很多錢，我會旅游七天。 3.If i had enough money,i would be going to e beijing is the capital city of china. 如果我有很多錢，我會去北京，因為北京是中國的首都。 4.If i had enough money,i would be going to qingdao with my friends. 如果我有很多錢，我會和我的朋友們去青島。 二、過去將來進行時表示在過去將來某一時間正在發(fā)生的動作，它常和表過去將來的時間狀語連用，但上下文清楚時，時間狀語亦可省略。和將來進行時一樣，它也常表計劃中的事，不表意愿或打算。它過去將來進行時可以表示在過去某一時間之后即將進行還有一個特點，即常用在賓語從句(尤其是間接引語)中。例如： 1.John told us that Mary would be going to Tianjin next

　過去進過去進行時由 was/were 加現(xiàn)在分詞構成。 　　例如： 　　What were you doing this time yesterday?昨天這個時候你在做什么? 　　During the summer of 1999 she was travelling in Europe.1999年夏天她在歐洲旅行。 　　He said he was leaving for home in a day or two. 他說他一兩天之內就動身回家了。 　　She was always thinking of others. 她老是想到別人。(贊揚) 　　She was forever complaining. 她老是抱怨。(厭煩) 　　I was reading the newspaper when the doorbell rang. 我正在看報，突然門鈴響了。 　　Jim burnt his hand when he was cooking the dinner. 吉姆做飯時把手燙了。 　　I met Diana while I was shopping this morning. 我今早買東西時碰到了戴安娜。 　　I was doing my homework while he was listening to music. 我在做作業(yè)而他在聽音樂。

能來因為要開會。 5.He asked me where i would be going at six the next day. 他問我次日六點將去哪里。 6.The new job he would be taking was translating the English books. 他將要接受的新過去將來進行時的基本結構是：“主語+should(would)+be+現(xiàn)在分詞”或者“was/were going to + 動詞原形”構成。過去將來進行時工作是翻譯英文書。 7.He said that he could not come because he would be going to hospital for an emergency . 他說他不能來因為他有緊急事情去醫(yī)院。 8.They said they would be reading Shakespeare next Monday. 他們說了他們將在下周一讀莎士比亞。 9.On May 18, the employee wrote to the council that he would be taking the doctor’s advice. 5月18日，這位雇員致信委員會，稱他將遵照醫(yī)囑。

行時的用法 A. 在某段時間內一直進行的動作用現(xiàn)在完成進行時來強調動作在某段時間里的持續(xù)性動作通常有"現(xiàn)在"的結果要根據(jù)上下文來確定到"現(xiàn)在"為止動作是否還在繼續(xù)進行同樣過去完成進行時表示在過去更早時間內進行的動作,并對過去某一時刻產(chǎn)生結果。 B.表示重復動作的現(xiàn)在/過去完成進行時 我們也可以用完成進過去完成時代替，例如： He had not practiced English for many years 他沒有練習英語很多年了。（普通說法） He had not been practicing English for many years. 很多年了，他一直沒有練習英語。（少見） 二、這種時態(tài)還可用在said，supposed等引起的間接引語中代替現(xiàn)在完成進行時 He said“I have been speaking to John”= He said that he had been speaking to John 他說“我一直和約翰說著話”。 He thought“She was watching me when I passed”= He thought that she had been watching him when he had passed 他想“當我經(jīng)過的時候，她正看著我”。 三、過去完成進行時經(jīng)常與現(xiàn)在完成進行時混淆。 現(xiàn)在完成進行時 (The present perfect progressive) 由 have/has been +-分詞構成 過去完成進行時 The past perfect progressive tenses 由 had been +-分詞構成 四、現(xiàn)在/過去完成進行時的用法 A. 在某段時間內一直進行的動作用現(xiàn)在完成進行時來強調動作在某段時間里的持續(xù)性動作通常有"現(xiàn)在"的結果要根據(jù)上下文來確定到"現(xiàn)在"為止動作是否還在繼續(xù)進行同樣過去完成進行時表示在過去更早時間內進行的動作,并對過去某一時刻產(chǎn)生結果。 B.表示重復動作的現(xiàn)在/過去完成進行時 我們也可以用完成進行時形式來表示現(xiàn)在或過去經(jīng)常重復的動作。 注意過去完成進行時和過去完成時類似需要有過去這一時間點。

行時主要表示過去某時的一個動作正在進行。例如： 1. I was writing a letter when she came to see me. 當她來看我時我正在寫信。 2.I had been writing a letter for two hours by the time she came to see me. 當她來看我的時候，我已經(jīng)寫了兩個小時的信了。 5. 過去完成進過去完成進行時是一種比較抽象的時態(tài)，學習它需要理解整個句子所處的語境和時間。過去完成進行時行時與過去完成時的不同。過去完成時表示過去某時間前已經(jīng)發(fā)生的動作或情況，這個過去的時間可以用by，before等介詞短語或一個時間狀語從句來表示；或者表示一個動作在另一個過去動作之前已經(jīng)完成。例如： 1. They had just had breakfast when Tom came in. 湯姆來時，他們剛吃過早飯。 2. They had been having breakfast for ten minutes when Tom came in. 湯姆來時，他們已經(jīng)吃了十分鐘的早飯了。

行時的被動態(tài)?；拘问剑簊hould/would have been being done. 請看例句： 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. 他說今年3月12日會有很多樹苗被學生種下，因為學校已經(jīng)決定這項活動了。 2. She said that by the end of last weekend, the book would have been being read for 2 weeks. 她說直到上周末，這本書就已經(jīng)被讀了兩周了。 3. This topic would have been being considered for a month. 這個話題已經(jīng)被考慮了1個月了。 4. Tom's room would have been being cleaned. 湯姆的房間會被打掃。 5. The play would have been being performed for 2 hours. 這場表演會持續(xù)兩小時。 6. Up to that time those books had been being translated. 直到那時，這些書還在被翻譯。 7. The letter had been being written till two o'clock. 寫這封信寫到了2點。 由基本形式轉過去將來完成進行時，表示動作從過去某時間開始一直延續(xù)到對于過去換為被動態(tài)還是挺簡單的，不過這里需要注意的是被動態(tài)的形式為should/would have been being done。請不要和過去將來完成時的被動態(tài)would + have + been + done混淆。前者為持續(xù)性動作，而后者并無持續(xù)性的意思。
