5 A 翻译：萨姆正带存款去邮局时，这时他把钱包丢了。解释：1. 此题考查when的一个特殊用法：when可以做并列连词，引导并列句，而不是做从属连词引导时间状语从句。此时when = and then，翻译为“就在这时”。此种用法要求前句2.必须为过去进行时或含有was/were about to do sth结构。2. while引导时间状语从句时，要求从句的谓语动词必须是延续性动词，而lost his wallet为一个终止性动词，排除。while引导并列句时，翻译为“与此同时/然而”，表示转折对比关系，不妥。3. as和Just as同样引导时间状语从句，一般翻译成“一边...，一边...”/“正当...的时候”，要求前后两个动作同时进行，也不是并列句用法，排除。
