過去進(jìn)行時(shí)when和while

1、。過去進(jìn)行時(shí)的講與練一、含義：(1) 過去進(jìn)行時(shí)表示過去某一時(shí)刻或者某段時(shí)間正在進(jìn)行或發(fā)生的動(dòng)作，常和表過去的時(shí)間狀語連用。(2) 過去進(jìn)行時(shí)表示感情色彩與現(xiàn)在進(jìn)行時(shí)相似，過去進(jìn)行時(shí)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 alwaysquarrelling.他們老是吵架。二、過去進(jìn)行時(shí)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(shí)間狀語有

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

3、ile we were 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(dòng)作都是延續(xù)性動(dòng)詞或同時(shí)發(fā)生的，兩句都用過去進(jìn)行時(shí)的時(shí)候，多用 while 引導(dǎo) 注意： when 和 while 的區(qū)別：都意為 “當(dāng) 時(shí)候 ”，when 引導(dǎo)的句子謂語動(dòng)詞用短暫性動(dòng)詞或延續(xù)性動(dòng)詞都行；但 while 引導(dǎo)的句子謂語動(dòng)詞只能用延續(xù)性動(dòng)詞，不能用短暫性動(dòng)詞。when 和 while 還可作并列連詞。 when表示 “在那時(shí) ”；while 表示 “而，卻 ”，表對(duì)照關(guān)系。

4、The children were running to move the bag of rice when they heard the sound of amotor bike.孩子們正要跑過去搬開那袋米，這時(shí)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(dòng)詞是非延續(xù)性動(dòng)詞，即動(dòng)作一開始便結(jié)束的動(dòng)詞，如come, go, begin,start, become, join, end, die, buy, arrive, reach, borrow,

5、 lend, get to know等。持續(xù)性動(dòng)詞，如learn, study, work, play, wait等練習(xí)：用when 或者 while填空。（ 1）we were waiting for the bus, a girl ran up to us.（2） I was telephoning a friendBob came in.（3） Jim jumped on the busit was moving away.-可編輯修改 -。（4） She wanted to stay in bedthe others were working in the fields.（ 5）mot

7、ight.湯姆昨晚給他的朋友寫了封信。（信寫完了）Tom was writing a 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(dòng)作的延續(xù)性）。過去進(jìn)行時(shí)練習(xí)一、用動(dòng)詞的適當(dāng)形式填空。1.it(rain) when you left school?2.One day, Edison(wait) for a train to arrive, and suddenly a littleboy ran to the track(軌道 ) to play.3.She(make) her dress the whole aft
