1.如何區(qū)別when和while引導的時間狀語從句（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，瞬間結束。

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

總結

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.過去進行時和一般過去時的區(qū)別過去進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)。結構形式主語+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行而可能尚未完成的動作。表示過去已經完成的動作。1)過去進行時表示過去正在進行的動作,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。(表達了他們已寫好的意思,整個寫的過程已完成。)講解：2)當動作延續(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）
