過去進(jìn)行時(shí)（2）:when、while、as學(xué)案

延續(xù)性動(dòng)詞表示能夠延續(xù)的動(dòng)作，這種動(dòng)作可以延續(xù)下去或產(chǎn)生持久影響。如：learn,work,stand,lie,know,walk,keep,have,wait,watch,sing,read,sleep,live,stay

非延續(xù)性動(dòng)詞也稱終止性動(dòng)詞、瞬間動(dòng)詞或短暫性動(dòng)詞，表示不能延續(xù)的動(dòng)作，這種動(dòng)作發(fā)生后立即結(jié)束。如：open,close,finish,begin,come,go,arrive,reach,getto,leave,move,borrow,buy

過去進(jìn)行時(shí)可與表示過去的時(shí)間狀語如atthattime,thewholemorning,allday,at7o’clock等時(shí)間狀語連用，也可與when，while，as引導(dǎo)的過去時(shí)間狀語連用，形成復(fù)合句。1、when所引導(dǎo)的時(shí)間狀語可指時(shí)間點(diǎn)或時(shí)間段，而while所引導(dǎo)的時(shí)間狀語只指時(shí)間段。因此，在when所引導(dǎo)的時(shí)間狀語從句中，動(dòng)詞可以是終止性動(dòng)詞或延續(xù)性動(dòng)詞；而在while從句中，動(dòng)詞必須是延續(xù)性動(dòng)詞。Eg.

①

_________myfatheropenedthedoor,Iwasdoingmyhomework.當(dāng)我父親打開門時(shí)，我正在做作業(yè)。②

_______________wewereplayingbasketball,theteacherwalkedby.我們正打籃球時(shí)，老師路過。WhenWhen/While2、當(dāng)when引導(dǎo)時(shí)間狀語從句時(shí)，從句的動(dòng)作可與主句的動(dòng)作同時(shí)發(fā)生，也可在其后發(fā)生；而while引導(dǎo)時(shí)間狀語從句時(shí)，主、從句的動(dòng)作必須同時(shí)發(fā)生或存在。Eg.

①Weweretalking__________________________.

①_________theheadteacherappeared,weweretalking.我們正在講話，校長(zhǎng)（突然）進(jìn)來了。②_________weweretalking,theheadteacherappeared.當(dāng)我們正在講話，校長(zhǎng)進(jìn)來了。（只表明了校長(zhǎng)進(jìn)來這一事實(shí)，而不強(qiáng)調(diào)突然性。）WhenWhile4、當(dāng)as引導(dǎo)時(shí)間狀語從句表示一件事情正在發(fā)生，另一件事也正在進(jìn)行的時(shí)候，不同于while從句，as從句一般不用進(jìn)行時(shí)，而用一般過去時(shí)，可譯成“邊...邊...；隨著...”。E.g.①Thegirlssang_______________________.
