一、過去進(jìn)行時(shí)的定義

過去進(jìn)行時(shí)主要表示過去某一時(shí)刻正在進(jìn)行的動(dòng)作，或表示過去某一階段一直在進(jìn)行的動(dòng)作。如：

I was having a talk with Li Hua at that time. 那時(shí)，我正在跟李華談話。

I was watching TV at home last night. 昨晚我一直在看電視。

二、如何理解過去進(jìn)行時(shí)：

三、過去進(jìn)行的構(gòu)成

過去進(jìn)行時(shí)由“was / were + 現(xiàn)在分詞”構(gòu)成。如：

Someone is knocking the door. 有人在敲門。

Steam was rising from the coffee. 咖啡冒著熱氣。

Clouds were flying across the sky. 云彩飄過天空。

注意有些was (were) doing sth不是現(xiàn)在進(jìn)行時(shí)，而是系表結(jié)構(gòu)，其中的doing sth是動(dòng)名詞，不是現(xiàn)在分詞。如：

Her job was washing clothes. 她的工作是洗衣裳。

Her hobby was growing roses. 她的愛好是種植玫瑰。

Her suggestion was having our conversation in French. 她的建議是我們用法語交談。

四、過去進(jìn)行時(shí)的主要用法

1. 表示在過去某一點(diǎn)時(shí)間或某一段時(shí)正在進(jìn)行的動(dòng)作。如：

I was having a bath when the phone rang. 我正在洗澡，突然電話鈴響了。

She was writing letters. I didn’t want to disturb her. 她在寫信。我不想打擾她。

2. 表示在過去短期內(nèi)正在進(jìn)行的動(dòng)作或存在的情況，這種情況通常不會(huì)長期如此。如：

It happened while I was living in Eastboume last year. 這件事發(fā)生于去年我住在伊斯特本的時(shí)候。

3. 表示為過去的將來安排好的活動(dòng)和事件。這類用法在沒有明確上下文的情況下，通常會(huì)連用一個(gè)表示將來時(shí)間的狀語。如：

He said that his sister was getting married next December. 他說他妹妹12月結(jié)婚。

用arrive, come, go, leave等動(dòng)詞的現(xiàn)在進(jìn)行時(shí)描寫行程安排，也通常有含有將來意義。如：

Four of them were coming for Sunday lunch. 他們有四個(gè)人將在星期天來吃午飯。

Her daughter was going to a summer camp the following day. 她的女兒將在第二天去參加夏令營。
