条码技术
条码技术是在计算机的应用实践中产生和发展起来的一种自动识别技术。它是为实现对信息的自动扫描而设计的，它是实现快速、准确而可靠地采集数据的有效手段。条形码技术的应用解决了数据录入和数据采集的瓶颈问题，为物流管理提供了有利的技术支持。条形码是由一组规则的条空及对应字符组成的符号，用于表示一定的信息。条形码技术的核心内容是通过利用光电扫描设备识读这些条形码符号来实现机器的自动识别，并快速、准确地把数据录入计算机进行数据处理，从而达到自动管理的目的。条码技术是实现POS系统、EDI、电子商务、供应链管理的技术基础，是物流管理现代化的重要技术手段。条码技术包括条码的编码技术、条码标识符号的设计、快速识别技术和计算机管理技术，它是实现计算机管理和电子数据交换不可少的前端采集技术。

条形码
条形码(barcode)是将宽度不等的多个黑条和空白，按照一定的编码规则排列，用以表达一组信息的图形标识符。常见的条形码是由反射率相差很大的黑条（简称条）和白条（简称空）排成的平行线图案。条形码可以标出物品的生产国、制造厂家、商品名称、生产日期、图书分类号、邮件起止地点、类别、日期等许多信息，因而在商品流通、图书管理、邮政管理、银行系统等许多领域都得到广泛的应用。

Section C(10 marks) In this section, there is one passage followed by 5 questions. Read the passage carefully, and then answer the questions in a maximum of 10 words. Remember to write the answers on the Answer Sheet.Pavarotti Dies Aged 71 The Italian opera star Luciano Pavarotti died at his home in Modena, aged 71. The tenor, who helped take opera to a new mass audience, had been diagnosed with pancreatic cancer last year and had further treatment in August 2007. His manager, Terri Robson, said Pavarotti died at 5 am on September 6. ‘The maestro fought a long, tough battle against the pancreatic cancer which eventually took his life. Characteristically, he remained positive until finally succumbing to the last stages of his illness,’ Mr. Robson said in a statement. Pavarotti was considered by some critics to have been the greatest tenor since Enrico Caruso. He made his professional debut in 1961, as Rodolfo in Puccini’s La Bohemeat the opera house in Reggio Emilia. His most celebrated performance came at New York’s Metropolitan Opera House, where he hit nine high Cs in Donizetti’s La fille du regiment. But Pavarotti reached a new global audience during the 1990 football World Cup, when his interpretation of the Puccini aria Nessun Dormawas chosen as the tournament’s theme tune. It became an international hit. Later, Essential Pavarotti became the first classical album to reach number 1 in the UK charts. The 1990 World Cup was also the venue of the first of the hugely popular Three Tenor concerts that Pavarotti performed with Placido Domingo and Jose Carreras. His most high-profile performance in Britain was the Pavarotti in the Park concert, in a rain-sodden Hyde Park in 1991. His friend, Diana, Princess of Wales, was in the front row. Like many opera stars, Pavarotti also had a reputation for being demanding. At a Royal Variety performance in Edinburgh, he reportedly demanded a fully fitted kitchen to be built into his hotel suite. He also frequently cancelled concerts at short notice. But he also raised millions of pounds for good causes around the world in a number of charity performances. Domingo led the tributes to his fellow tenor. ‘I always admired the God-given glory of his voice,’ he said. ‘I also loved his wonderful sense of humor and on several occasions during our concerts with Jose Carreras we had trouble remembering that we were giving a concert before a paying audience, because we had so much fun between ourselves.’ The British tenor Russell Watson told GMTV that Pavarotti was ‘without question’ the man who brought opera to the people. “The World Cup was the Three Tenors led by Pavarotti, with a very entertaining version of Nessun Dorma. In fact, it’s now called ‘Pavarotti’s Nesson Dorma’,” Watson said. ‘His voice was so distinctive you only needed to listen to a couple of bars and you knew it was him, he had incredible power and control.’ QUESTIONS: 1．What was the cause of Pavarotti’s death? 2．Where did Pavarotti first perform professionally? 3．Who were The Three Tenors? 4．How did Pavarotti raise money for good causes? 5．Which piece of operatic music do people usually associate with Pavarotti?

威海丽园大酒店在开业之初曾以“5个第一”而闻名，诸如第一个在大厅安装感应自动门，第一个在楼前及屋顶亮起五彩缤纷的霓虹灯，第一个采用泛光灯装置等。还成为韩国商人的“商场酒店”，被全国旅游界视为一绝。餐饮不是“丽园”的强项，却同样受到领导极大的关注。大酒店的刘总经理经常与餐饮部几位主要负责人聚在一起研究菜点的供应情况。2004月底的一个上午，在刘总的办公室里正开着一个小型会议，与会者有总经理办公室主任、餐饮部经理、厨师长和两位餐厅主管，每人手里拿着一份最近两个月的菜点销售状况分析表。表的左面是菜单上的菜点名称，最上面一行是日期，注出了星期几，每周有个“小计”，表内主体部分是每种菜点的销售量，表的最右面是每天平均销售量。“从本表可以看出，我们最近才推出的清炒西葫芦销售情况呈上升趋势。8月份从第一个星期的180份一直稳步上升，到第四个星期为270份，我认为在考虑新菜单的时候仍应保留此菜。”一位主管首先坦陈自己的看法。“我同意。另外，我认为肉丸子沙锅也应该保留。一方面，这是我们的看家菜，已有相当的名声；另一方面从销售情况看，每天的销售量始终保持在190份上下，变动范围在40之内。这说明我们的顾客喜欢这道菜。”厨师长接着发言。“红煨羊肉的销售状况看上去波动较大，但如果仔细分析一下的话，内中有一定的规律，每周星期六和星期日的销售量激增。在其余日子则情况平平。因此这道菜有保留的价值，但在用料方面须作调整，星期六和星期日两天多准备一些原料，以满足需求。餐饮部经理谈了自己的意见。他们对每道菜进行了认真细致的分析，把销售情况呈明显下降趋势的以及近阶段内一直销售不佳的4道菜删去。餐饮部经理和厨师长提议试销葱爆腰花和蚝油牛肚等6道菜，获得一致赞同。根据所学知识谈谈菜单定价方法。
