Whatdifferencescanyoufindbetweenwhenandwhile

when+一般過去時，while+過去進行時

過去進行時中when和while引導(dǎo)的時間狀語從句

過去進行時常和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。

不同點1：

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。

e.g.Weweretalkingwhentheteachercamein.

我們正在交談，這時老師進來了。

Theyarrivedwhen/whilewewerehavingdinner.

當(dāng)我們正在吃晚飯時，他們到了。

不同點2：

由when引導(dǎo)的時間狀語從句常用一般過去時，而主句用進行時；如果強調(diào)從句和主句的動作同時發(fā)生，兩句都用過去進行時，且多用while引導(dǎo)從句

e.g.Iwaswalkinginthestreetwhentheaccidenthappened.

我正在街上散步，這時這起交通事故發(fā)生了。

TheaccidenthappenedwhenIwaswalkinginthestreet.

當(dāng)我正在街上散步時，這起事故發(fā)生了。

IsawtheaccidentwhileIwaswalkingontheroad.

當(dāng)我正在街上散步時，我看見了這起交通事故。

一般過去時過去進行時過去進行時

歸納

如果主句和從句都用了過去進行時，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號班機由上海飛往北京后再飛往洛杉磯。一架麥道MD-11型客機執(zhí)行此一航班時起落架發(fā)生故障。飛機起后折返虹橋國際機場緊急迫降，全機人員安全，這是中國首宗民航飛機迫降事件。

當(dāng)飛機起飛后，機長發(fā)覺飛機的前起落架指示燈未能由紅色轉(zhuǎn)為熄掉，表示不能收回，于是機長通知虹橋國際機場塔臺，塔臺同意飛機回航。當(dāng)證實前起落架不能收回及降下后，機組人員欲在空中將前起落架降下，首先將飛機降下再爬升，之后再以小半徑側(cè)滑，但未能將前起落架降下來。其后，機長指示一名機務(wù)查看起落架的狀況，該名機務(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，機場及飛機均開始進行迫降前的準備，機上的空服員呼吁乘客盡量移往機尾后方，飛機則于上空盤旋以消耗燃油，機場跑道亦噴上防火泡沫，減低起火的機會。晚上11時7分，飛機在前端噴上防火泡沫的跑道上降落，機長首先讓后起落架先觸地，之后機頭在跑道上摩擦，并且跟地面拖出一條火花，當(dāng)滑行至380米后，飛機終于停下了。

最終，北京時間11:07分，這架飛機在滑行了380米后停穩(wěn)在跑道內(nèi)。飛機停下之后，乘客紛紛離開飛機，消防員就向飛機射水以防止起火，并協(xié)助乘客離開現(xiàn)場，有9人在離開飛機時因為逃生滑梯漏氣而跌傷。全機人無一遇難。是中國民航史上的重大飛躍。
