ready 和 set up 有什么区别？如果难以说明的话，请教我一下例句。

Ready is very general purpose. Are you ready? He's ready to go. I'm finally ready to get married. Set up refers only to cases where something needs to be done to prepare for use. For example, a desktop computer needs to be set up before someone can use it. A bank account needs to be set up as well. The idea is that anything "set up" or the process of "setting something up" needs a person, or a few people, to put time into making something ready. It's an active process. Ready can be passive.
