過(guò)去進(jìn)行時(shí)

1.概念：表示過(guò)去某段時(shí)間或某一時(shí)刻正在發(fā)生或進(jìn)行的行為或動(dòng)作。

2.時(shí)間狀語(yǔ)：

at this time yesterday,at that time或以when引導(dǎo)的謂語(yǔ)動(dòng)詞是一般過(guò)去時(shí)的時(shí)間狀語(yǔ)等。

3.基本結(jié)構(gòu) 主語(yǔ)+was/were +doing +其它

4.否定形式：主語(yǔ)+was/were + not +doing+其它

5.一般疑問(wèn)句：把was或were放于句首。(第一個(gè)字母大寫)

6.例句：At that time she was working in a PLA unit.那段時(shí)間她在人民解放軍部隊(duì)工作。

When he came in,I was reading a newspaper.他進(jìn)來(lái)時(shí)，我正在讀報(bào)紙。

由助動(dòng)詞be 的過(guò)去式 + 現(xiàn)在分詞構(gòu)成。其中be有人稱和數(shù)的變化，第一、第三人稱單數(shù)用was，其他用were.

1)過(guò)去進(jìn)行時(shí)動(dòng)詞主要表示在過(guò)去某一時(shí)刻或某一段時(shí)間內(nèi)正在進(jìn)行或持續(xù)進(jìn)行的動(dòng)作。過(guò)去進(jìn)行時(shí)經(jīng)常與過(guò)去時(shí)配合使用。例如：

This time yesterday, we were having an English lesson. 昨天這個(gè)時(shí)候，我們正在上英語(yǔ)課。

The teacher was giving us a lesson when Tom walked into the room. 老師在給我們上課時(shí)，湯姆走進(jìn)教室。

He was reading while she was setting the table. 她擺桌子時(shí)，他在讀書。

It was getting dark. The wind was rising. 天漸漸黑下來(lái)了。風(fēng)勢(shì)增強(qiáng)了。

2)過(guò)去進(jìn)行時(shí)動(dòng)詞常用always, continually, frequently 等詞連用，表示過(guò)去經(jīng)常發(fā)生的行為。這種用法表明帶有的感情色彩。例如：

The two brothers were frequently quarreling when they were young. 兩兄弟小時(shí)候常吵架。

In Qing Dynasty, China was always making concessions to western powers. 清朝時(shí)，中國(guó)總是對(duì)西方列強(qiáng)妥協(xié)。
