When my husband was going into the dining-room this morning , he dropped some coins on the floor.
There were coins everywhere. We looked for them, but we could not find them all.
While we were having breakfast, our little boy, Tommy, found two small coins on the floor.
He put them both into his mouth. We both tried to get the coins, but it was too late. Tommy had already swallowed them!
Later that morning, when I was doing the housework, my husband telephoned me from the office.
“How’s Tommy?” he asked.
“I don’t know,” I answered, “Tommy’s been to the lavatory three times this morning, but I haven’t had any change yet!”
2．Tommy had already swallowed them! 汤米已经把硬币咽了下去！
句中用了过去完成时形式 had swallowed。过去完成时用来表示过去两个动作中发生在前的那个动作。显然，句中咽下硬币的动作发生在夫妇俩能够把硬币从汤米手中抢过来之前。
3．later that morning,那天上午的晚些时候。
过去进行时表示过去某时正在进行的情况或动作。过去进行时和一般过去时经常在同一个句子里使用。过去进行时表示过去正在进行的情况或动作，一般过去时则表示比较短暂的动作或事件。过去进行时的时间状语从句一般由when，while及（just）as等来引导，说明主句中动作发生时的背景。此外，可用 while或 at the time等强调同时进行的两种或几种动作。请看例句：
When I was doing the housework, my husband telephoned me from the office.
While I was listening to the stereo, my mother came into the room.
Just as she was cleaning her shoes, George knocked at the door.
While I was cooking the dinner ,he was working in the garden.
