過去進(jìn)行時(shí),是表示過去某個(gè)時(shí)刻或時(shí)間段正在進(jìn)行的事情或動(dòng)作。

過去進(jìn)行時(shí)謂語(yǔ)動(dòng)詞結(jié)構(gòu):was/were +doing (現(xiàn)在分詞)
三. 用法
1.過去進(jìn)行時(shí)表示過去某段時(shí)間內(nèi)持續(xù)進(jìn)行的動(dòng)作或者事情。
常用的時(shí)間狀語(yǔ)this morning, the whole morning, all day yesterday, from nine to ten last evening, when, while等。例如:
We were watching TV from seven to nine last night.
昨天晚上七點(diǎn)到九點(diǎn)的時(shí)候我們?cè)诳措娨暋?/p>
What was he researching all day last Sunday?

他們離開車站的時(shí)候天正在下雨。
When I got to the top of the mountain, the sun was shining.
當(dāng)我到達(dá)山頂?shù)臅r(shí)候,陽(yáng)光燦爛。
2. 過去進(jìn)行時(shí)可以表示在過去某個(gè)時(shí)間點(diǎn)發(fā)生的事情。
時(shí)間點(diǎn)可以用介詞短語(yǔ)、副詞或從句來表示。例如:
What was she doing at nine o'clock yesterday?
昨天晚上九點(diǎn)她在做什么? (介詞短語(yǔ)表示時(shí)間點(diǎn))
She was doing her homework then.
那個(gè)時(shí)候她正在寫作業(yè)。(副詞表示時(shí)間點(diǎn))
When I saw him he was decorating his room.
當(dāng)我看見他的時(shí)候他正在裝飾房間。 (when從句表示時(shí)間點(diǎn))
3. 在復(fù)合句中,如果主要?jiǎng)幼骱捅尘皠?dòng)作都是延續(xù)的或同時(shí)發(fā)生的,那么主從句的動(dòng)詞都可用過去進(jìn)行時(shí)。
When he was waiting for the bus, he was reading a newspaper.
他邊等車邊看報(bào)。 (兩個(gè)動(dòng)作都是延續(xù)的)
He was cleaning his car while I was cooking.
他擦車時(shí)我在做飯。(兩個(gè)動(dòng)作同時(shí)進(jìn)行)
【典型例題】
1) Mary ___ a dress when she cut her finger.
A. made
B. is making
C. was making
D. makes
答案C. 割傷手指是已發(fā)生的事情,應(yīng)用過去時(shí)。同時(shí),when表時(shí)間的同時(shí)性,“瑪麗在做衣服時(shí)”提供事情發(fā)生的背景,因此用過去進(jìn)行時(shí)。
2) As she ___ the newspaper, Granny ___ asleep.
A. read; was falling
B. was reading; fell
C. was reading; was falling
D. read;fell
答案B.句中的as = when, while,意為"當(dāng)……之時(shí)"。描述一件事發(fā)生的背景時(shí),用過去進(jìn)行;一個(gè)長(zhǎng)動(dòng)作發(fā)生的時(shí)候,另一個(gè)短動(dòng)作發(fā)生。句意為 "在她看報(bào)紙時(shí),奶奶睡著了。"句中的 fell (fall的過去時(shí)),是系動(dòng)詞,后跟形容詞,如:fall sick。
四. 過去進(jìn)行時(shí)和一般過去時(shí)的區(qū)別
1. 一般過去時(shí)敘述舊事,過去進(jìn)行時(shí)描述背景。
2.一般過去時(shí)表示行為的“整體”和存在的狀態(tài),過去進(jìn)行時(shí)表某一行為的“片斷”。
I read the book yesterday. (已讀完,表整個(gè)“讀”)
I was reading the book at that time. (未讀完,“讀”的片段)
3. 過去的一段持續(xù)時(shí)間狀語(yǔ)多與過去進(jìn)行時(shí)連用。
It was raining all night.(優(yōu)先用was raining ,rained 為持續(xù)動(dòng)詞,故也可使用)
He was writing a letter the whole of afternoon. (短暫動(dòng)詞與持續(xù)時(shí)間連用,表反復(fù),連續(xù)發(fā)生,不可用一般過去時(shí))
五. 注意
英語(yǔ)中有四類動(dòng)詞一般不用進(jìn)行時(shí)(不用現(xiàn)在進(jìn)行時(shí)和過去進(jìn)行時(shí))。
1. 表心理狀態(tài)、情感的動(dòng)詞
如love ,hate ,like ,care ,respect ,please ,prefer ,know 等,若用進(jìn)行時(shí)則詞意改變。
I’m forgetting it . (=beginning to forget )
2. 表存在、狀態(tài)的動(dòng)詞
如appear ,exist ,lie ,remain ,stand ,seem等。
3. 表感官的動(dòng)詞
如see ,hear ,feel ,smell ,sound ,taste等。
4. 表非延續(xù)性的動(dòng)詞
如accept ,allow ,admit ,decide ,end ,refuse ,permit ,promise等。
