過去進(jìn)行時when和while

1、過去進(jìn)行時的講與練一、含義：(1)過去進(jìn)行時表示過去某一時刻或者某段時間正在進(jìn)行或發(fā)生的動作，常和表過去的時間狀語連用。(2) 過去進(jìn)行時表示感情色彩與現(xiàn)在進(jìn)行時相似，過去進(jìn)行時也可表示滿意、稱贊、驚訝、厭惡等感情色彩，也通常與always，forever等副詞連用。e.g：They were always quarrelling. 他們老是吵架。二、過去進(jìn)行時的構(gòu)成和用法：肯定形式：主語+was/were+doing否定形式：主語+was not (wasnt)/were not (werent)+doing疑問形式：Was/Were+主語+doing。常與之連用的時間狀語有，at that

2、 time/moment, (at) this time yesterday (last night/Sunday/week), at+點(diǎn)鐘+yesterday (last night / Sunday)，when 和while引導(dǎo)的時間狀語從句。三、when/while引導(dǎo)的時間狀語從句由when/while 引導(dǎo)的時間狀語從句。常用句型：a. 主句（主語 + was/were + doing when + 一般過去時的句子）；表示主句動作發(fā)生的過程中，另一個意想不到的動作發(fā)生了。We were talking when the teacher came in.=While we were

3、talking, the teacher came in.b. 主句（主語 + was/were + doing while +主語 + was/were + doing ）；主句與從句的動作都是延續(xù)性動詞或同時發(fā)生的，兩句都用過去進(jìn)行時的時候，多用while引導(dǎo)注意：when和while的區(qū)別：都意為“當(dāng)時候”，when引導(dǎo)的句子謂語動詞用短暫性動詞或延續(xù)性動詞都行；但while引導(dǎo)的句子謂語動詞只能用延續(xù)性動詞，不能用短暫性動詞。when和while 還可作并列連詞。when表示“在那時”；while表示“而，卻”，表對照關(guān)系。The children were running to mo

4、ve the bag of rice when they heard the sound of a motor bike.孩子們正要跑過去搬開那袋米，這時他們聽到了摩托車的聲音。He is listening to music while his brother is playing computer.他正在聽音樂，而他弟弟卻在玩電腦。短暫性動詞是非延續(xù)性動詞，即動作一開始便結(jié)束的動詞，如come, go, begin, start, become, join, end, die, buy, arrive, reach, borrow, lend, get to know等。持續(xù)性動詞，如le

6、ell rang.（6）He was listening to music he was riding his bike. （7）They didnt make a model ship I saw him.（8）He is strong his brother is weak.四、一般過去時與過去進(jìn)行時的用法比較： 一般過去時表示“在過去某個時間發(fā)生的動作或存在的狀態(tài)”，而過去進(jìn)行時則表示“在過去某個特定時間正在進(jìn)行的動作”。如：Tom wrote a letter to his friend last night. 湯姆昨晚給他的朋友寫了封信。（信寫完了）Tom was writing a

7、 letter to his friend last night. 湯姆昨晚一直在給他的朋友寫信。（信不一定寫完，只是強(qiáng)調(diào)了動作的延續(xù)性）。過去進(jìn)行時練習(xí)一、 用動詞的適當(dāng)形式填空。1. it (rain) when you left school?2.
