田遥大喝道：他去了多久？明心结巴道：有……半……个多时辰……了。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.贺老三，一个纵横江湖数十年的贼中之贼，一辈子只栽过一次，就是栽在十年前，刚刚走上擦的警察张旭光和李智手中。十年之后，贺老三重病缠身，不久于人世，他惟一的心愿是，把他的老对手张旭光和李智二人打趴下，以此洗刷他此生最大的耻辱。贺老三带着手下返回故乡云州，设计了一系列迷局，连续策划了防盗门盗窃案、公交车盗窃案、珠宝盗窃案等等案子，试图声东击西，浑水摸鱼。而以张旭光和李智为首的新警事，吸收了一批李成儒，以新的侦破手段、新的办案理念，来应对新形势下的新犯罪手段。在侦破这一系列社会影响较大的窃案过程中，新警事的成员们逐渐逼近事实真相，摸清了贺老三的底细……老对手卷土重来，较劲的背后，到底隐藏着什么不可告人的目的？张旭光和李智又该如何见招拆招？一场官兵捉强盗的游戏进行得惊心动魄，警察们的忠诚勇猛智慧，令人折服，贼们也有贼们的胆识谋略，最终还是邪不压正，贺老三落入法网。刑警们并没有因为贼王落网而庆幸，他们有着更深入的思考：要实现社会和谐生活安定的最终目的，对待贼们除了抓堵，更重要的是疏导。张旭光小镇盗窃案频频发生，一只梦想成为大侦探的猫咪为了找出真凶决定离家出走。旅途中的她遇到了一只自认风度翩翩的公鸡，一只梦想成为马戏团明星的驴，一只仇恨人类的守门狗。四只小动物历经磨合，即将找出真凶时，却被误认为是偷窃真凶。他们该如何证明清白，如何守护友谊和梦想……　　认识了余倩倩。(2) Civil Aircraft Driver License (Business License or Route Transportation License)绿菠人小，如何经得起他这一撞，接连后退两步，一屁股坐在地上，手上的桂花酥也飞了，落在门槛附近翻了两滚，停下来。
