過去進(jìn)行時是表示過去某一時刻或某一時間內(nèi)正在進(jìn)行或發(fā)生的動作。可以從兩個方面來理解：1 過去某一時刻正在進(jìn)行或發(fā)生的動作。E.g. They were playing football at ten o’clock yesterday morning. My mother was cooking when I got home. I was washing my clothes at this time yesterday. 2 過去某階段持續(xù)進(jìn)行的動作 What were you doing during the holiday? 另外，在復(fù)合句中，若主要動作和背景動作是同時發(fā)生的，那么主從句都可用過去進(jìn)行時e.g. Jenny was reading while Danny was writing.

　　其結(jié)構(gòu)是助動詞be的過去形式was/were +v-ing.

　　其句式變化仍然要在be上做文章。E.g. We were working in class.

　　We weren’t working in class. Were you working in class?

　　過去進(jìn)行時常與過去某一特定時間的狀語連用，如 last night, at that time, at noon yesterday, last Sunday 等。也有時沒有時間狀語，要通過上下文的暗示來確定用過去進(jìn)行時。E.g. The students all worked hard. Everyone knew what he was working for.

　　做題時常見錯誤如下：

　　一、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(jìn)行時與現(xiàn)在進(jìn)行時結(jié)構(gòu)上的區(qū)別體現(xiàn)在be動詞上。

　　二、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(jìn)行時中“be+現(xiàn)在分詞,缺一不可”的規(guī)律也可應(yīng)用于過去進(jìn)行時。

　　三、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(jìn)行時中“What……doing……”?句式同樣適用于過去進(jìn)行時。

　　四、易與現(xiàn)在進(jìn)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(diǎn)是都表示動作正在進(jìn)行，但現(xiàn)在進(jìn)行時前提是現(xiàn)在，而過去進(jìn)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(diǎn)是都用于表示過去發(fā)生的動作。但過去進(jìn)行時強(qiáng)調(diào)動作正在進(jìn)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。“在”說明正在進(jìn)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(jìn)行時。

　　另外，在賓語從句中當(dāng)主句為過去時，從句若是現(xiàn)在進(jìn)行時，需變成過去進(jìn)行時。

　　e.g. He said that he was drawing a cat at noon yesterday.
