精讲笔记：
1. The whole village soon learnt that a large sum of money had been lost.
整个村子很快知道，有一大笔钱丢失了。
语言点1 the whole village指“全村的人”，后常接动词单数。常用表达还有：

语言点2 had been lost是过去完成时的被动语态。
2. Sam Benton, the local butcher, had lost his wallet while taking his savings to thepost office.
当地的屠夫萨姆·本在把存款送往邮局的途中把钱包弄去了。
语言点1 the local butcher 为 Sam Benton 的同位语。
语言点2 while taking是一个省略形式(时间状语从句变成分词作状语)
这种情况必须具备两个条件：
这个动作的主语跟主句的主语一致;
这个动作一定是正在进行。
原句完整的形式应该是：Sam Benton, the local butcher, had lost his wallet while he was takinghis savings to the post office.
3. Sam was sure that the wallet must have been found by one of the villagers, but itwas not returned to him.
