表示過(guò)去某一時(shí)刻或某段時(shí)間內(nèi)正進(jìn)行的動(dòng)作。2.構(gòu)成:was/were+動(dòng)詞現(xiàn)在分詞3.用法:

a:表示某一時(shí)刻正進(jìn)行的行為,與特定的過(guò)去時(shí)間狀語(yǔ)連用,常見(jiàn)的時(shí)間有:at8lastnight,atthistimeatthattime,atthatmoment等這一特定的過(guò)去時(shí)間除有上下文特定時(shí)間點(diǎn)暗示以外,一般用時(shí)間when/while引導(dǎo)時(shí)間狀語(yǔ)從句來(lái)表示。.例如:A:Whatwereyoudoingateightlast

night?

1.如何區(qū)別when和while引導(dǎo)的時(shí)間狀語(yǔ)從句（主要看動(dòng)詞）讀語(yǔ)法中的句子找規(guī)律。1)延續(xù)性動(dòng)詞和非延續(xù)性動(dòng)詞

延續(xù)性動(dòng)詞指動(dòng)作可以延續(xù)一段時(shí)間,而不是瞬間結(jié)束。

如:work、study、drink、eat，read,watchlisten,wait,write,swim,sing等。

非延續(xù)性動(dòng)詞指動(dòng)作極為短暫，瞬間結(jié)束。

如:come,go,start、begin、hit、jump、knock,buy,sell,borrow,die,join,see,meet等。。

總結(jié)

1)when可指時(shí)間點(diǎn),又可指時(shí)間段,從句中可用延續(xù)性動(dòng)詞,也可用短暫性動(dòng)詞。

2)while總是指一個(gè)時(shí)間段,從句中必須用延續(xù)性動(dòng)詞。短暫性動(dòng)詞往往用過(guò)去式，延續(xù)性動(dòng)詞用Was/weredingLookatthetableandwritesentenceswithbothwhileandwhen.4aWhileJohnwastakingphotos,Maryboughtadrink.Johnwastakingphotos
