9、ile引導的從句謂語只能用延續(xù)性動詞。Sorry,Iwasoutwhenyoucalledme.Whentheywerehavingsupper,someonecalledonher.Itbegantorainwhilewewerewalkinginthepark.2.主從句動作發(fā)生的順序while引導的從句的謂語動詞所表示的動作通常與主語謂語動詞所表示的動作同時發(fā)生，而when引導的從句的謂語動詞表示動作可以發(fā)生在主句謂語動詞表示動作之前，之后，也可以同時發(fā)生When/Whileweweredancing,astrangercamein.Whenhehadfinishedhishomewor

10、k,hetookashortrest.WhenIgottothestation,thetrainhadleft.(二)過去進行時1.概念：表示過去某段時間或某一時刻正在發(fā)生或進行的行為或動作。2.時間狀語：atthistimeyesterday,atthattime或以when引導的謂語動詞是一般過去時的時間狀語等。yesterday,last,ago,before,in+年或月,on+日,justnow(或者amomentago)3.基本結(jié)構(gòu)：was/were+doing4.否定形式：was/were+not+doing.5.一般疑問句：把was或were放于句首?！爸饕硎驹谶^去的某個時間

11、點上正在發(fā)生、進行的動作。由于它的定義是表示在過去的某個時間點上正在發(fā)生、進行的動作，所以，句子常帶有一個表示過去某個時間點”的狀語。這個狀語可能是短語，詞組，或是一個從句。也可能是通過上下文來表達這層意思。過去進行時主要用于下面的情景中：1）表示在過去某時刻正在進行的動作，例如：Atthismomentyesterday,Iwaspackingforcamp.昨天這個時候，我正在收拾東西去露營。WhenIcametoseeherlasttime,shewaswritinganarticle.上次我來看她的時候，她正在寫一篇文章。Whatwereyoudoingateightlastnight

12、?昨晚八點鐘你在做什么？2）用于故事的開頭，交代故事發(fā)生的背景情況。過去進行時所描述的動作是“正在進行”，所以，在這種情景中用“過去進行時”可以給讀者一種“動感”，從而能使文章更加生動活潑。例如：.Onenight,hewastypinginhisstudy.Suddenly,amanbrokeintohishouseandcutofftheelectricity一天晚上，他正在書房里打字。突然，一個人闖進屋來，切斷了電源3)（僅限少數(shù)動詞）表示在過去的未來時間要發(fā)生的動作。例如：.WhenNationalDaywascomingnear,theybegantomakeaplanfortheh

13、oliday國慶節(jié)即將來臨的時候，他們開始制訂度假計劃。ShetoldmethatshewasgoingtoHainanforherholiday.她告訴我她將去海南度假。.Myfriendsaidtomethathewaslunchingwithoneofhiscustomersthatday我朋友對我說，他今天要與他的一位客戶一塊兒吃午飯。Welefttherewhenitsgettingdark.天快黑的時候，我們離開了那兒。6.用過去進行時表示現(xiàn)在，主要是為了使語氣委婉、客氣。如：Iwaswonderingifyoucouldgivemealift.我不知你能否讓我搭一下車。Wewer

14、ehopingyouwouldstaywithus.我們很希望你能跟我們住在一起。Howmuchdidyouwanttospend,sir?先生，您打算花多少錢？注：一般過去時也有類似用法，但比較而言，用過去進行時顯得更客氣，更不肯定。過去進行時專項練習題：一、用動詞的適當形式填空1.Whilewe_(wait)forthebus,agirl_(run)uptous.2.I_(telephone)afriendwhenBob_(come)in.3.Jim_(jump)onthebusasit_(move)away.4.We_(test)thenewmachinewhentheelectrici
