这里介绍几种REBOL中的选择语句，这些方法提供了一个按照关键值运行多种分支的方法。
There are several methods to selectively evaluate expressions in REBOL. These methods provide a way for evaluation to branch many different ways, based on a key value.
传统的服务发现通常是以服务的功能性描述信息作为关键值进行服务发现，往往忽略了服务的非功能性描述信息。
The traditional service discovery mechanism used functional described information as a key to discover a service, it usually ignores the non-functional service descriptions.
