本课语法
1．look for，寻找（强调动作过程）；find，找到（强调寻找的结 果）。 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。 later是副词late的比较级。 4．any change change是个多义词，既有“零钱”的意思，也有“变化”的意思。此 处既可指“硬币”；也可指“情况的变化”。这是双关（pun /p)n/） 修辞法。
