三年前，女大学生丽丽因徐氏兄弟的过失，不幸身亡。受了三年牢狱之苦的徐达文，与孪生兄弟徐达武相见后却因神秘纠纷反目成仇。而从这一天开始，徐达文常常能感觉到自己可以看到鬼魂在身边游荡，就像是拥有了阴阳眼一样。徐达武似乎也开了天眼，看到了最近所发生的离奇事件，似乎都指向了三年前的一场“意外”。In real life, China's income tax is divided into enterprise income tax, foreign-invested enterprises or foreign-invested enterprises income tax and personal income tax. For these three types of income tax, each is calculated in a different way. Personal income tax has a personal income tax calculation method, while enterprise income tax has its corresponding calculation method. If we do not adopt the policy mode to realize such a requirement, we will define an income tax class, which has an attribute to identify the type of income tax and a CalculateTax () method to calculate the tax. In this method, we need to judge the tax type and calculate the income tax for different tax types through if-else statements. Such an implementation can indeed solve this scenario, but such a design is not conducive to expansion. If the system needs to add an income tax in the later period, it has to go back and modify the CalculateTax method to add an additional judgment statement, which clearly violates the principle of "open-closed". At this time, we can consider using the strategic mode to solve this problem. Since the tax method is the changing part of this scenario, we can naturally think of abstracting the tax method at this time, which is also the essence of the implementation of the strategic mode.在英国与西班牙的战争中，女王展现出的强大魄力，把大不列颠推向霸主的辉煌巅峰。"Weekend Day Voucher"On January 29, 2015, Department of Civil Aviation Malaysia announced that Malaysia Airlines Flight MH370 crashed and presumed that all 239 passengers and crew on board had been killed.……来到启明影视的会客厅。2.
