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

延續(xù)性動詞指動作可以延續(xù)一段時間,而不是瞬間結(jié)束。

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

非延續(xù)性動詞指動作極為短暫，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可指時間點,又可指時間段,從句中可用延續(xù)性動詞,也可用短暫性動詞。

2)while總是指一個時間段,從句中必須用延續(xù)性動詞。短暫性動詞往往用過去式，延續(xù)性動詞用Was/weredingLookatthetableandwritesentenceswithbothwhileandwhen.4aWhileJohnwastakingphotos,Maryboughtadrink.Johnwastakingphotos

4.過去進(jìn)行時和一般過去時的區(qū)別過去進(jìn)行時一般過去時基本用法表示在過去的某一時刻或某一時間正在進(jìn)行的動作。過去某個時間發(fā)生過的動作或存在的狀態(tài)。結(jié)構(gòu)形式主語+was/were+V-ing形式主語+動詞過去式時間狀語at7yesterday,atthattime,thistimelastnight等;when與while引導(dǎo)的時間狀語從句。yesterday,lastweek,in1993,once,before,afewdaysago等。友情提示表示一個過去正在進(jìn)行而可能尚未完成的動作。表示過去已經(jīng)完成的動作。1)過去進(jìn)行時表示過去正在進(jìn)行的動作,而一般過去時則表示一個完整的動作。如:Theywerewritingletterstotheirfriendslastnight.昨晚他們在寫信給他們的朋友。(沒有說明信是否寫完)Theywroteletterstotheirfriendslastnight.他們昨晚寫了信給他們的朋友。(表達(dá)了他們已寫好的意思,整個寫的過程已完成。)講解：2)當(dāng)動作延續(xù)較長時間時或表示厭煩、贊美等感情色彩時,常用過去進(jìn)行時

表示。如：Hewasthinkingmoreofothersthanofhimself.他考慮別人的比考慮自己的多。(表示說話者贊揚的口氣)Theboywasalwaysmakingtroublethen.那時,他總是惹麻煩。(表示說話者厭煩的口氣）
