過(guò)去進(jìn)行時(shí)的概念：

過(guò)去進(jìn)行時(shí)表示在過(guò)去某一時(shí)刻或某一段時(shí)間內(nèi)進(jìn)行或發(fā)生的動(dòng)作。其形式為was /were + V-ing。
常與表示過(guò)去的時(shí)間狀語(yǔ)連用，如：last night, last Saturday等；或者與when, while, as引導(dǎo)的過(guò)去時(shí)間狀語(yǔ)連用。

過(guò)去進(jìn)行時(shí)的基本用法：　　

1、主要表示過(guò)去某一時(shí)間正在進(jìn)行的動(dòng)作：
如：He fell asleep when he was reading. 他看書時(shí)睡著了。　　
We were expecting you yesterday. 我們昨天一直在等你�！　�
He was playing while I was studying. 我在做功課時(shí)他在玩�！　�
2、過(guò)去進(jìn)行時(shí)表示現(xiàn)在：　　
用過(guò)去進(jìn)行時(shí)表示現(xiàn)在主要是為了使語(yǔ)氣委婉、客氣。
如：I was wondering if you could give me a lift. 我不知你能否讓我搭一下車。　　
We were hoping you would stay with us. 我們很希望你能跟我們住在一起�！　�
How much did you want to spend, sir? 先生，您打算花多少錢？　　
【注】一般過(guò)去時(shí)也有類似用法，但比較而言，用過(guò)去進(jìn)行時(shí)顯得更客氣，更不肯定�！　�
3、過(guò)去進(jìn)行時(shí)表示感情色彩：　　
與現(xiàn)在進(jìn)行時(shí)相似，過(guò)去進(jìn)行時(shí)也可表示滿意、稱贊、驚訝、厭惡等感情色彩，也通常與always, forever, continually等副詞連用。
如：They were always quarrelling. 他們老是吵架�！　�
The boy was continually asking questions. 這個(gè)男孩子老是問(wèn)東問(wèn)西的。　　
4、動(dòng)詞be的過(guò)去進(jìn)行時(shí)：　　
動(dòng)詞be的進(jìn)行時(shí)也可表示過(guò)去一時(shí)的表現(xiàn)或暫時(shí)的狀態(tài)。
如：He was friendly. 他很友好。(指過(guò)去長(zhǎng)期如此) 　　
He was being friendly. 他當(dāng)時(shí)顯得很友好。(指當(dāng)時(shí)一時(shí)的表現(xiàn))

過(guò)去進(jìn)行時(shí)與一般過(guò)去時(shí)的區(qū)別：

（1）過(guò)去進(jìn)行時(shí)強(qiáng)調(diào)動(dòng)作在過(guò)去某時(shí)刻正在進(jìn)行或持續(xù)，而一般過(guò)去時(shí)表示動(dòng)作的完成。
如：He was writing his composition last night. 他昨晚在寫作文。(不一定寫完)
He wrote his composition last night. 他昨晚寫了一篇作文。(已經(jīng)寫完)
（2）表示過(guò)去的狀態(tài)、感覺及心理活動(dòng)的靜態(tài)動(dòng)詞（如be, like, love, hate, fear, own, hear, see, know, want, notice）可用于一般過(guò)去時(shí)，但通常不用于進(jìn)行時(shí)。
如：I hated it when a man spoke with his mouth full of food. 我討厭人們說(shuō)話時(shí)口里含著食物。
（3）一般過(guò)去時(shí)與always, constantly, forever, continually等連用，表示“過(guò)去經(jīng)常性、習(xí)慣性的動(dòng)作”；
而過(guò)去進(jìn)行時(shí)與always, constantly, forever, continually等連用，表示動(dòng)作的重復(fù)，常帶有感情的色彩。
如： He always got up at six. 他過(guò)去總是六點(diǎn)起床。
He was always thinking of his work. 他總是一心想到工作。
（4）有時(shí)過(guò)去進(jìn)行時(shí)可以用來(lái)替換一般過(guò)去時(shí)，但一般過(guò)去時(shí)表示主語(yǔ)的行為是經(jīng)過(guò)認(rèn)真考慮的；
而過(guò)去進(jìn)行時(shí)表示一種較隨便或沒(méi)有進(jìn)行仔細(xì)考慮的行為。
如：I thought that he would agree with us. 我原以為它會(huì)同意我們的。
I was thinking of persuading him to follow my advice. 我想到了要說(shuō)服他接受我們的建議。

如：Tom was getting up at six o'clock every day that week. 湯姆那一周里每天都是六點(diǎn)鐘起床。

4、when作并列連詞，表示“（這時(shí)）突然”之意時(shí)，第一個(gè)并列分句用過(guò)去進(jìn)行時(shí)，when引導(dǎo)的并列分句用一般過(guò)去時(shí)。
