as 含义理解
这是布林肯说的：
As we commemorate Victory in Europe Day, we honor the shared resilience and resolve that defeated the Nazis.
麻烦老师讲讲这里的as的含义？
以及对比
When we commemorate Victory in Europe Day, we honor the shared resilience and resolve that defeated the Nazis.
While we commemorate Victory in Europe Day, we honor the shared resilience and resolve that defeated the Nazis.
这3个词经常混淆使用，没有真正明白三者之间的区别是什么？
谢谢老师们！

仔细研究As we commemorate Victory in Europe Day, we honor the shared resilience and resolve that defeated the Nazis.as引导状语从句，我们发现纪念欧洲胜利日，这里的纪念（commemorate）的含义，由 honor the shared resilience and resolve that defeated the Nazis.展示出来，也就是说，as引导的状语从句，主句解释，补充，增添，详细展示了as从句的内容，例如：As I soon learnt， he was English himself（我很快了解到，他自己就是个英国人！）这里的 learnt的含义，就是他自己就是个英国人。在自考综合英语二（徐克容主编）第九课有个句子：
As my taxi drove to the airport I wondered if my plane could take off in such weather（在乘出租车去机场路上，我就怀疑在这样天气下我班机是否能起飞。）.显然，我的担心伴随着去机场的路上，作者用主句补充，增添，详细展示了as从句的内容。when时间性比较强，给主句提供一个“时间背景”，在自考综合英语二（徐克容主编）第11课有个句子
When I was born my father was a well-to-do master weaver in Scotland.
而while表达了一种“对比”在自考综合英语一下（徐克容主编）第15课有个句子
While my father was out at bricklaying, earning the bread and butter for us, Mother was slowly, patiently pulling down the wall, brick by brick,....
对此，徐克容教授评论这句话说：这是个状语从句表示对比，说明父母一个在外，一个在家，为同一目的，干着不同的事。（P414）
当然了as when,while用法比较复杂，需要仔细体会。
