當(dāng)飛機(jī)到達(dá)時(shí)，一些偵探等候在主樓內(nèi)，另一些偵探則守候在停機(jī)坪上。
（1）這個(gè)長(zhǎng)句子由3個(gè)部分組成：when引導(dǎo)的是整個(gè)句子的時(shí)間狀語(yǔ)從句；some of…building為主句；while 引導(dǎo)的是動(dòng)作與主句的動(dòng)作同時(shí)進(jìn)行的時(shí)間狀語(yǔ)從句。while作為連詞表示“和……同時(shí)”、“當(dāng)……時(shí)候”時(shí)常常引導(dǎo)一個(gè)過(guò)去進(jìn)行時(shí)從句。（cf. 本課語(yǔ)法）
（2）地點(diǎn)狀語(yǔ) on the airfield 與第一句中的 at the airport 意義相近。注意介詞on和at的不同搭配。

這個(gè)短語(yǔ)中的所有格形容詞their也可以換成其他所有格形容詞：(much) to my/ his surprise, to our surprise 等。一般不說(shuō) to your surprise.
語(yǔ)法 Grammar in use
1．過(guò)去進(jìn)行時(shí)(The past progressive tense)
構(gòu)成：be的過(guò)去式+現(xiàn)在分詞（注意現(xiàn)在分詞的構(gòu)成）
（1）過(guò)去進(jìn)行時(shí)主要表示過(guò)去某個(gè)時(shí)刻或某段時(shí)間正在進(jìn)行的動(dòng)作。過(guò)去進(jìn)行時(shí)和一般過(guò)去時(shí)經(jīng)常同在一個(gè)句子里使用。過(guò)去進(jìn)行時(shí)表示過(guò)去正在進(jìn)行的動(dòng)作或情況，一般過(guò)去時(shí)則表示比較短暫的動(dòng)作或事件。正在進(jìn)行中的動(dòng)作或情況往往由連詞 when, while, as, just as等引導(dǎo)：
While/ When/ As I was sweeping the floor, I found your pen.
我掃地的時(shí)候，發(fā)現(xiàn)了你的鋼筆。
while通常只引導(dǎo)持續(xù)時(shí)間較長(zhǎng)的動(dòng)作，并且主句和從句可以同時(shí)用過(guò)去進(jìn)行時(shí)，而when和as一般不這么用：
John was watching TV while his wife was talking with a neighbour over the phone.
當(dāng)他的妻子和一位鄰居在電話中聊天時(shí)，約翰一直在看電視。
Some students were dancing and singing while others were eating and drinking.
有些學(xué)生在唱歌跳舞，而另一些則在吃喝。
Just as I was opening the front door, the telephone rang.
我正開前門的時(shí)候，電話鈴響了。
Just as I was leaving the house, you came in.
你進(jìn)來(lái)的時(shí)候我正要出門。
when也可以引導(dǎo)比較短暫的動(dòng)作，while和as則一般不行：
We were having supper when the lights went out.
我們正在吃晚飯時(shí)燈滅了。
2）過(guò)去進(jìn)行時(shí)往往與表示一段時(shí)間的狀語(yǔ)連用，如all morning, all night, all day, all evening, the whole week等，表示這段時(shí)間一直在干什么：
They were preparing for the party for two whole days.
整整兩天他們一直在為晚會(huì)進(jìn)行準(zhǔn)備。 2．短語(yǔ)動(dòng)詞中的小品詞(The particles)
在上一課的語(yǔ)法中已經(jīng)提到，許多動(dòng)詞加上介詞或副詞后就會(huì)改變?cè)~義。這些介詞和副詞通常被稱為小品詞。它們沒有詞形變化。有些小品詞既可以作介詞又可以作副詞。判斷一個(gè)小品詞是副詞還是介詞要看小品詞有沒有帶賓語(yǔ)。有賓語(yǔ)的是介詞，沒有賓語(yǔ)的是副詞。介詞的位置相對(duì)固定些：I am looking for Tim.
我在找蒂姆。（for為介詞，位置不能變動(dòng)）
She looked after the baby.
她照顧那孩子。（after為介詞）
He put the fire/ it out.
他滅了火。（out為副詞）
Mother woke the children/ them up.

Put the cake on the table.
把蛋糕放在桌上。（on為介詞）
She is walking up the hill.
