问题：翻译1It'spossiblethatithasdevelope 
It's psible that it has developed over the years from when people used to say many years ago "be of good cheer"or "good cheer to you ". This would have been a greeting to wish someone well that has been shortened to "cheers " over time . 
回答：一种可能的解释是：以往人们用的“祝精神气爽”或“祝笑口常开”，经过长期的演变，发展成了今天的形式。这些短语原来是人们见面打招呼的用语，现在简化到了仅仅是“cheers”。
