设计高校人员信息包，并完成测试

【题目描述】定义一个人员类People，其属性有：姓名、性别、年龄；基于People实现学生类Student，添加属性：学号、入学时间和入学成绩；基于People实现教师类Teacher，添加属性：职务、部门、工作时间；基于Student实现究生类Graduate，添加属性：研究方向和导师，分别定义其中的构造函数和输出函数。程序中定义各种类的对象，并完成测试。 基于以上类利用接口实现在职研究生类 GradOnWork。

【源代码程序】

# 创建一个 GradOnWork 对象

grad_on_work = GradOnWork()

# 调用 display() 方法打印信息

grad_on_work.display()
