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.编剧高欣悦苦心创作的剧本《一纸寄风月》在参加总公司创投会前，被同事舒妙改的面目全非并私自提交。在去总公司撤回剧本的路上，高欣悦意外穿越进剧中世界，成为三阿哥凌泓的侍妾。在线频道CBS All Access的新剧《一元背后 One Dollar》（前名《》）由Jason Mosberg主创，神秘﹑惊悚题材的该剧背景在经济衰退下，美国的锈带小镇（锈带指美国东北部地区，过去此区有钢铁产业，但荒废后工厂余下锈迹大门而得名）中一张一元美金钞票会被不停转手，并牵涉到多个角色﹑命案及披露城镇里的秘密。该剧定于美国时间8月30日上线。主演包括John Carroll Lynch﹑Nathaniel Martello-White﹑Chris Denham﹑Philip Ettinger﹑Kirrilee Berger﹑Gracie Lawrence﹑Joshua Bitton﹑Níkẹ Uche Kadri及Hamilton Clancy。电视剧《因爱之名》是一部充满曲折悬念的都市情感伦理剧，讲述了一个关于年轻人面对仇恨、爱情和权力时如何选择的故事。In fact, in the past two years, not only has online children's thinking ability training been highly praised by capital, but also interactive game APP and offline mode training institutions related to thinking ability training have received financing one after another.
