              1.if XXX
             
              //如果 条件1 满足 执行条件1的消息体，并执行条件2
             
              2.if XXX
             
              //不管条件1是否成立，2都会执行，
             
              3.else if XXX
             
              //如果条件2成立，则不执行3，不成立，则执行3
             
              总结 if else 只会就近原则，和最近的成套判断
