概念
過去進(jìn)行時(shí)表示在過去某一時(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。常與表示過去的時(shí)間狀語連用,如:last night, last saturday等;或者與when, while, as引導(dǎo)的過去時(shí)間狀語連用。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?
上周日他一整天都在研究什么?
用法
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。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))
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:
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)
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, forget, 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。
誤:i wasn’t understanding him.
正:i didn’t understand him. 我不明白他的意思。
句型
肯定句:主語+was/were+doing+其它
否定句:主語+was/were+not+doing+其它
一般疑問句及答語:was/were+主語+doing+其它
特殊疑問句:特殊疑問詞+was/were+主語+doing+其它
過去進(jìn)行時(shí)和一般過去時(shí)的區(qū)別
過去進(jìn)行時(shí)表示過去某時(shí)正在進(jìn)行的動(dòng)作,而一般當(dāng)兩個(gè)延續(xù)動(dòng)作同時(shí)進(jìn)行時(shí),二者都可用過去進(jìn)行時(shí)表達(dá)。
