title: wouldratherdosth看成是真实的句子还是虚拟的句子？ 
answer:   
            Would rather do/not do不是虚拟语气.
            以下两个是虚拟语气的用法：
            1. *would rather sb did (对现在或将来的虚拟)
            2. Would rather sb had done(对过去的虚拟)
             Would rather 其他用法:
             宁做A而不做B:
             Would rather do A than do B
             =Would do rather than do 
             =Prefer to do rather than do 
           Rather than refuse to help you, I would borrow 
           money f my friends.
         *------Did Frank call you yesterday?
         ------Yes, but I would rather he hadn’t .
