英語語法：過去進(jìn)行時(shí)
【導(dǎo)語】英語語法讓很多學(xué)生都頭疼，因?yàn)閺?fù)雜難懂的句式和詞組有時(shí)難以記憶。為大家整理了初一英語語法大全，希望對同學(xué)們的英語語法學(xué)習(xí)有所幫助。
過去進(jìn)行時(shí)(Past continous tense)：表示過去某時(shí)正在進(jìn)行的動(dòng)作(不強(qiáng)調(diào)是否完成)。主要用法是描述一件事發(fā)生的背景;一個(gè)長動(dòng)作發(fā)生的時(shí)候，另一個(gè)短動(dòng)作發(fā)生。
一、常用的時(shí)間狀語：this morning、the whole morning、all day yesterday、from nine to ten last evening、when、while等等。例如：
1. 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，陽光燦爛。 )
2. What was he researching all day last Sunday? (上周日他一整天都在研究什么?)
3. My brother fell while he was riding his bicycle and hurt himself.(我哥哥騎自行車的時(shí)候從車上摔下來，受傷了。)
4. It was raining when they left the station.(他們離開車站的時(shí)候天正在下雨。 )
二、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、副詞或從句來表示。例如：
介詞短語表示時(shí)間點(diǎn)——What was she doing at nine o'clock yesterday? (昨天晚上九點(diǎn)她在做什么?)
when從句表示時(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。)
三、 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)。例如：
兩個(gè)動(dòng)作都是延續(xù)的——While he was waiting for the bus, he was reading a newspaper. (他邊等車邊看報(bào)。)
兩個(gè)動(dòng)作同時(shí)進(jìn)行——He was cleaning his car while I was cooking.(他擦車時(shí)我在做飯。)
四、通常不能用于過去進(jìn)行時(shí)的動(dòng)詞主要有：agree、be、believe、belong、care、forge、hate、have(擁有)、hear、know、like、love、mean、mind、notice、own、remember、seem、suppose、understand、want、wish等。例如：
誤：I was knowing the answer.
正：I knew the answer.(我知道答案。)
五、典型例題：
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)。
