新概念英語第一冊117-118課課文重難點詳解 further notes on the text
1．look for，尋找（強調(diào)動作過程）；find，找到（強調(diào)尋找的結(jié)果）。
2．tommy had already swallowed them! 湯米已經(jīng)把硬幣咽了下去！
句中用了過去完成時形式 had swallowed。過去完成時用來表示過去兩個動作中發(fā)生在前的那個動作。顯然，句中咽下硬幣的動作發(fā)生在夫婦倆能夠把硬幣從湯米手中搶過來之前。
3．later that morning,那天上午的晚些時候。
later是副詞late的比較級。
4．a(chǎn)ny change
change是個多義詞，既有“零錢”的意思，也有“變化”的意思。此處既可指“硬幣”；也可指“情況的變化”。這是雙關(guān)（pun /p)n/）修辭法。

過去進行時
構(gòu)成： be的過去式+現(xiàn)在分詞。
過去進行時表示過去某時正在進行的情況或動作。過去進行時和一般過去時經(jīng)常在同一個句子里使用。過去進行時表示過去正在進行的情況或動作，一般過去時則表示比較短暫的動作或事件。過去進行時的時間狀語從句一般由when，while及（just）as等來引導(dǎo)，說明主句中動作發(fā)生時的背景。此外，可用 while或 at the time等強調(diào)同時進行的兩種或幾種動作。請看例句：
when i was doing the housework, my husband telephoned me from the office.
當我正在干家務(wù)時，我丈夫從辦公室打電話給我。
while i was listening to the stereo, my mother came into the room.
我正在聽立體聲節(jié)目時，我母親進房間了。
just as she was cleaning her shoes, george knocked at the door.
她正在擦鞋時，喬治敲門了。
while i was cooking the dinner ,he was working in the garden.
我做飯時，他正在花園里勞作。
