Questions 26-30 are based on the following passage: In a glabal sruvey raleased in 2012,half the responders admitted to buying things they really did not need.Two thirds are worried that consumers are buying too much.Such concerns may be justified.Many consumers have become trapped in debt.Researchers say that instead of making us more satisfied,high levels of consumption may lead to greater stress and unhappoiness! As consumers,we are subjected to a great amount of marketing.What is the goal of marketers?To turn wants into needs.Marketers know that consumer behavior is driven largely by emotion.So advertisements and the shopping experience itself are designed for maximum emotional appeal. When you ask a counsumer:Why do you buy so much?He or she may answer:I want to improve my quality of life.It is natural that people want a better life.Advertises bombard us with messages that all of our desires--better health,security, relief from stress,and close relationships--can be achieved by making the right purchases. But actually,as our number of possessions increases,our quality of life can actually derease.Addtional time and money are needed to care for more material things.Stress levels rise because of pressure from debt,and there is less time for family and friends.So you should protecet yourself from debt,and there is less time for family and friends.So you should protect yourselg from becoming a victim of clever marketers.You should put emotion aside,and compare marketing promises with reality. The word "bombard"in the third paragraph is closest in meaning to"（）".

试题四(共25分) 阅读以下关于面向对象系统建模的叙述，在答题纸上回答问题。[说明] 某软件企业为影音产品销售公司W开发一套在线销售系统，以提升服务的质量和效率。项目组经过讨论后决定采用面向对象方法开发该系统。在设计建模阶段需要满足以下设计要求：(1)W公司经常进行促销活动。根据不同的条件(如订单总额、商品数量、产品种类等)，公司可以提供百分比折扣或现金减免等多种促销方式供提交订单的用户选择。实现每种促销活动的代码量很大，且会随促销策略不同经常修改。系统设计中需要考虑现有的促销和新的促销，而不用经常地重写控制器类代码。(2)该在线销售系统需要计算每个订单的税率，不同商品的税率及计算方式会有所区别。所以W公司决定在系统中直接调用不同商品供应商提供的税率计算类，但每个供应商的类提供了不同的调用方法。系统设计中需要考虑如果公司更换了供应商，应该尽可能少地在系统中修改或创建新类。 项目组架构师决定采用设计模式来满足上述设计要求，并确定从当前已经熟练掌握的设计模式中进行选择，这些设计模式包括：适配器模式(Adapter)、构造器模式(Builder)、命令模式(Command)、外观模式(Facade)、中介模式(Mediator)、原型模式(Prototype)、代理模式(Proxy)、状态模式(State)和策略模式(Strategy)等。 针对题目中所提出的设计要求(1)和(2)，项目组应该分别选择何种设计模式请分别用200字以内文字说明具体的解决方案。
