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.怎么可能？花无缺呆呆的站在原地，死得明明应该是他，为什么小鱼儿死了？这怎么可能？啊——燕南天发出悲痛欲绝的吼声，忍不住一掌打向花无缺。　　故事女主原型Rose Cartwright的网站「Intrusive Thoughts」进一步解释说，许多纯粹强迫症患者是完美主义者，对于自己大脑应该思考什么有很高的标准。此类人会花时间分析他们为什么会有这些想法，以及这些想法对他们作为一个人的引导。如果无法达到控制他们大脑的这种标准，他们将会得出结论，认为自己是坏人或怪物。我国首部解读中国制造文化密码，弘扬航空报国精神的电视剧。该剧以严谨的现实主义创作精神书写了新中国航空工业70年悲壮伟大的奋斗历程，题材宏大、行业尖端，具有很强的标志性和引领性。多年后，魏仲廷因解严而赦免出狱，他克服了恐惧，到张明晖的坟上祭扫后“返校”，到即将因都更改建为大厦的翠华中学，将张明晖的绝笔信与定情之物白鹿项链，交给了方芮欣的灵魂。
