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.把刚才这些话告诉她，让她万不可莽撞行事。怀有滑冰梦想的冬冬和爸爸生活在一起，他需要一个新冰鞋和伙伴们去参加冰雪节的冰雪娃娃大赛，经济情况不好的爸爸没有给他买新冰鞋，父子发生争执，冬冬为此赌气出走，在外过程中他遇到了两个小偷，他的勇敢善良最终感化了他们，他们和冬冬还有他的伙伴们一起打败了一个破坏冰雪节活动的国际大盗，而冬冬的这次曲折冒险经历，也让他感受到了爸爸的不易而改变了对爸爸的态度，他重新拥抱了亲情，而冬冬和他的伙伴们也得到了一种成长。电视剧《神的测验》讲述的是韩国的顶尖监察医生队伍的推理、原因不明的神秘案件等等内容。柳德焕在剧中扮演的人物名叫韩智努，是韩国最顶尖的神经外科专科医生，但是却是一个恃才傲物的家伙。(6) Relationship between draft and available water depth.身边站着一个双十年华的少fù，眉目含春正殷勤地shì奉着。
