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.嗨，你就说说。　　1949年3月5日，中共中央七届二中全会在这里召开。毛泽东在报告中指出：“夺取全国胜利，这只是万里长征走完了第一步。……中国的革命是伟大的，但革命以后的路程更长，工作更伟大，更艰苦。这一点现在就必须向党内讲明白，务必使同志们继续地保持谦虚、谨慎、不骄、不躁的作风，务必使同志们继续地保持艰苦奋斗的作风。”杨家多女，无一男丁，老母亲奚月兰经常感叹自己命运不济，四个女儿没一个让她省心顺心的。大女儿杨丽颖才貌双全，大学毕业后留校执教，为杨家挣足了脸面。令人不可思议的是，杨丽颖鬼迷心窍的与一家小医院当勤杂工的冯罡结了婚，婚后没几天便生了女儿杨小旋。因婚姻不如意远走美国一去就是八年，毫无归家之意，留给奚月兰的只有一份遥远的思念。二女儿杨丽坤算是嫁了个刑警队长，可夫妻二人硬要做丁克族，不要孩子，老母亲奚月兰使出浑身解数也无法说服改变主意。三女儿杨丽萍更是奚月兰的一块心病，三十岁的人了，死活不找男朋友，谁跟她提这事，不是沉默就是跟你急，为了应付老母亲，尽雇佣一画家做自己签约男朋友。四女儿杨四改二十八岁了，却找了一个痞子男朋友，经常在外边闹事不说，还拿杨四改不当人，动不动就拳脚相加，杨四改提出和他分手，他尽在老太太大寿之日找上门大吵大闹，提出让杨家给他两万元分手费，奚月兰被气得差点犯了心脏病。幸有大女婿冯罡诸事张罗，里外操劳，凡重活脏活累活全由冯罡一人承担。忠厚老实的冯罡从无半句怨言，勤勉从事，不敢有半　　说的故事发生在明朝，当时，秦淮河畔夜夜笙歌，南京城里就有一条著名的街道，“春秀街”，之所以被贯以这个名字，因为此地乃是单身男女汇集拍托的场合，被誉为南京城最令人神往的地方……15岁的高中生科迪（弗朗基·穆尼兹 Frankie Muniz 饰）平凡得不能再平凡。他和所有年轻人一样，喜欢滑板，讨厌功课，爱出风头，但在喜欢的女孩面前却又结结巴巴。正因为他的平凡，毫不引人注目，所以中情局今次把他招了进来。在接受了一系列特训后，科迪接受了他的生平第一 个任务。
