過去進行時表示過去某一時刻或某一段時間內(nèi)正在進行或發(fā)生的動作。

★ 過去進行時的基本構(gòu)成

過去進行時由“助動詞be的過去式（was / were） + 動詞的現(xiàn)在分詞”構(gòu)成，其中was用于第一、三人稱單數(shù)，were用于第二人稱單、復數(shù)和其他人稱的復數(shù)。

肯定句為“主語 + was / were + V-ing”。如：

She was scared because a man was following her at that time.

她很害怕，因為當時有一個男人在跟蹤她。

The Smiths were having breakfast at 6：00 this morning.

今天早上6點史密斯一家正在吃早飯。

否定句為“主語 + was / were + not + V-ing”。如：

Alice wasn’t doing her homework when her mom came back.

當她媽媽回來時，愛麗絲沒有在做作業(yè)。

一般疑問句為“Was / Were + 主語 + V-ing”，肯定回答為Yes， 主語 + was / were，否定回答為No， 主語 + wasn’t / weren’t。如：

—Were your parents watching TV at this time yesterday？

昨天這個時候你的父母在看電視嗎？

—Yes， they were. / No， they weren’t.

是的，他們在看。/不，他們沒在看。

特殊疑問句為“疑問詞（組） + was / were + 主語 + V-ing？”如：

What were you doing when I called you up？

我給你打電話的時候你在干什么？

★ 過去進行時的基本用法

1. 過去進行時表示過去某個具體時刻或某一段時間內(nèi)正在進行或持續(xù)進行的動作，常與之連用的時間狀語有then， at that time / moment， at this time yesterday （last night / Sunday / week...）， at+幾點鐘+yesterday（last night / Sunday...）， those days， from 9 to 11 yesterday morning， the whole morning等。如：

I was doing my homework at this time yesterday.

昨天這個時候我正在做作業(yè)。

They were playing football at four o’clock yesterday afternoon.

昨天下午4點他們正在踢足球。

2. 過去進行時還可以表示過去同時發(fā)生的兩個持續(xù)性的動作，常用while或when連接，從句中要用延續(xù)性動詞作謂語。如：

When / While my father was reading a newspaper， I was drawing a horse.

當我父親在讀報紙的時候，我正在畫一匹馬。

3. 用于對比發(fā)生在過去的持續(xù)性動作和短暫性動作，可以用when或while將兩個動作連接起來。這時，持續(xù)性動作用過去進行時，而短暫性動作用一般過去時，即：“一般過去時 + while / when + 過去進行時”或“過去進行時 + when + 一般過去時”。如：

While I was listening to music， the door opened.

我正在聽音樂的時候，門開了。

The students were playing games when Mr Wang came in.

學生們正在做游戲，這時王老師進來了。

[有些動詞通常不用于過去進行時，如like， love， hate等表示心理狀態(tài)、情感的動詞;appear， seem等表示表象的動詞;see， feel， sound等感官動詞;allow， decide， end等短暫性動詞。][注意]

★ 一般過去時與過去進行時的區(qū)別

1. 一般過去時表示過去某個時間發(fā)生的動作或存在的狀態(tài)，動作往往已經(jīng)完成或結(jié)束;而過去進行時則表示過去某個時間正在進行的動作，動作往往還未完成。如：

Jim wrote a letter to his friend last night.

昨晚吉姆給他的朋友寫了一封信。（信寫完了）

Jim was writing a letter to his friend when his father came back.

他爸爸回來的時候，吉姆正在給他的朋友寫信。（信不一定寫完）

2. 一般過去時和過去進行時都可以表示過去某段時間內(nèi)發(fā)生的動作或存在的狀態(tài)，但一般過去時只說明過去發(fā)生了某事的事實，而過去進行時常用來說明持續(xù)性的動作或狀態(tài)，側(cè)重于動作持續(xù)時間的長度。如：

My grandpa worked in the factory ten years ago.

我爺爺10年前在這個工廠工作。

I often went swimming while I was living in Dalian.

我在大連住的時候經(jīng)常去游泳。
