Observe the fllwing sentences.
While the lights were changing t red, a car suddenly appeared rund the crner.I was trying t pick it up when it bit me again.
What differences can yu find between when and while?
when+ 一般過去時， while+過去進(jìn)行時
過去進(jìn)行時中when和while引導(dǎo)的時間狀語從句
過去進(jìn)行時常和when, while 引導(dǎo)的時間狀語連用，構(gòu)成復(fù)合句。兩者之間既有相同點，也有不同點。 相同點：when和while都可表示“當(dāng)······時”，用來引導(dǎo)時間狀語從句，表示主句動作發(fā)生的背景。
when可以指時間點，也可以指一段時間，while只指一段時間，因此在引導(dǎo)時間狀語從句時，when引導(dǎo)的時間狀語從句中的動詞可以是瞬間動詞，也可以是延續(xù)性動詞，而while從句中的動詞必須是延續(xù)性動詞。 were talking when the teacher came in. 我們正在交談，這時老師進(jìn)來了。 They arrived when/while we were having dinner. 當(dāng)我們正在吃晚飯時，他們到了。
由when引導(dǎo)的時間狀語從句常用一般過去時，而主句用進(jìn)行時；如果強(qiáng)調(diào)從句和主句的動作同時發(fā)生，兩句都用過去進(jìn)行時，且多用while引導(dǎo)從句e.g.I was walking in the street when the accident happened. 我正在街上散步，這時這起交通事故發(fā)生了。 The accident happened when I was walking in the street. 當(dāng)我正在街上散步時，這起事故發(fā)生了。 I saw the accident while I was walking n the rad. 當(dāng)我正在街上散步時，我看見了這起交通事故。
歸納 如果主句和從句都用了過去進(jìn)行時，那么從句用 引導(dǎo); 如果從句是一般過去時，要用 引導(dǎo)；如果主句是 ，從句是 ，從句可用when或while引導(dǎo)。

1998年9月10日中國東方航空586號班機(jī)由上海飛往北京后再飛往洛杉磯。一架麥道MD-11型客機(jī)執(zhí)行此一航班時起落架發(fā)生故障。飛機(jī)起后折返虹橋國際機(jī)場緊急迫降，全機(jī)人員安全，這是中國首宗民航飛機(jī)迫降事件。 當(dāng)飛機(jī)起飛后，機(jī)長發(fā)覺飛機(jī)的前起落架指示燈未能由紅色轉(zhuǎn)為熄掉，表示不能收回，于是機(jī)長通知虹橋國際機(jī)場塔臺，塔臺同意飛機(jī)回航。當(dāng)證實前起落架不能收回及降下后，機(jī)組人員欲在空中將前起落架降下，首先將飛機(jī)降下再爬升，之后再以小半徑側(cè)滑，但未能將前起落架降下來。其后，機(jī)長指示一名機(jī)務(wù)查看起落架的狀況，該名機(jī)務(wù)纏上繩子后冒險從前起落架艙門口探出身體，并用斧頭敲打起落架出現(xiàn)故障的地方，但未見松動。接著，機(jī)長用后起落架著陸，但仍然毫無反應(yīng)，結(jié)果就唯有迫降。
晚上10時10分，機(jī)場及飛機(jī)均開始進(jìn)行迫降前的準(zhǔn)備，機(jī)上的空服員呼吁乘客盡量移往機(jī)尾后方，飛機(jī)則于上空盤旋以消耗燃油，機(jī)場跑道亦噴上防火泡沫，減低起火的機(jī)會。晚上11時7分，飛機(jī)在前端噴上防火泡沫的跑道上降落，機(jī)長首先讓后起落架先觸地，之后機(jī)頭在跑道上摩擦，并且跟地面拖出一條火花，當(dāng)滑行至380米后，飛機(jī)終于停下了。最終，北京時間11:07分，這架飛機(jī)在滑行了380米后停穩(wěn)在跑道內(nèi)。 飛機(jī)停下之后，乘客紛紛離開飛機(jī)，消防員就向飛機(jī)射水以防止起火，并協(xié)助乘客離開現(xiàn)場，有9人在離開飛機(jī)時因為逃生滑梯漏氣而跌傷。 全機(jī)人無一遇難。是中國民航史上的重大飛躍。
