They are more powerful and reliable and, importantly, are very economical in terms of energy consumption. Their presence opens a new era in the field of IT technologies and means that the cloud technology is getting closer. These processors are primarily designed for servers, data centers (DPC) and supercomputers. The emergence of this class of devices is not accidental. According to the regional director of Intel in Russia and other CIS states Dmitri Konash who spoke at the event, the market of IT-technology is developing so rapidly that, according to forecasts, by 2015 there will be 15 billion devices connected to the Internet, and over 3 billion of active users. 上周，英特尔公司向俄罗斯和其它独联体国家的公众推出了英特尔Xeon E5-2600系列处理器，它们更加强大可靠，尤其是在能量消耗方面更加经济实惠。它们的问世意味着IT技术领域开始了一个新时代，标志着云技术距离我们越来越近。这些处理器主要是为服务器、数字处理中心和超级计算机设计的。这种处理器的出现并非偶然。根据英特尔公司俄罗斯和其他独联体地区负责人Dmitri Konash就此事发表的看法，IT技术市场的发展速度极快，根据预测，到2015年与英特网连接的设施将有150亿，用户超过30亿。 [Ex 6] 1.

第9单元电子商务第一部分听力和对话对话：使用在线支付服务保护消费者的隐私 (Henry非常兴奋地在一家网上书店中发现了自己期待已久的图书，但是当得知系统要求通过账号支付时，他犹豫了。) Henry: 最近互联网上信用卡账号的公然欺骗无疑为我们敲响了警钟。在进行在线交易时，我们并不知道要把自己的信用卡账号告诉谁。 Mark: 也许你可以使用第三方支付服务来保证在线支付更简单、更安全。 Henry: 什么是第三方支付服务？ Sophie: 简单地说，在使用第三方支付服务时，你可以把自己的资金转移到一个在线账号中，然后从那个账号中进行支付。这样就不用把自己的真实信用卡或银号账户信息暴露在网络上了。 Henry: 这种方法听起来更安全。有哪些第三方支付服务可以方便地使用？ Mark:在美国最受欢迎的服务是eBay公司掌控的PayPal,但也有一些其他的服务，如https://www.doczj.com/doc/166438477.html, Payment等。以最简单的支付为例，例如在线拍卖或简单的网站销售，销售商只需要向买家提供他们的E-mail地址，而买家向销售商的PayPal账号进行适当的支付。Henry: 我明白了。 Sophie: 做出选择之后，建议你留意选择更加安全服务的一些细节。 Henry: 什么是更加安全服务的一些细节呢？ Sophie: 首先，阅读隐私政策，并确保自己同意其中的条款。如果不同意，可以继续选择其他的安全服务。此外，确认网站符合权威部门规定的特定的标准（查验同意的盖章）。这些的确都是非常重要但是有时被用户忽略的步骤。 Mark: 当使用第三方支付服务时，Henry,请记住千万不要回复来自第三方支付服务机构发送的要求确认如密码或其他私人身份识别信息等与账号细节相关的电子邮件。这些邮件很可能是身份盗窃骗局，如网络钓鱼。 Henry: 那么，怎样才能更安全地确认或处理我的账号细节呢？ Sophie: 如果需要确认或更新账号信息或者修改密码，我建议你可通过个人书签或者在浏览器中直接输入支付服务网站的URL来访问相应的网站。 Henry: 如何进一步确认卖家能够提供有效的支付服务？ Mark: 你可以通过查看卖家在几个月或更长的时间内是否为支付服务机构的有效成员来确定。有些网站还允许用户查看卖家的评价，虽然这些评价并不能作为保证，但是却是非常有用的信息。 Sophie: 切记，Henry,不要用自己的账号把资金转移到一个你不认识的人的账号里。这可能是一种高级的资金诈骗。还有，当你要购买一些诸如珠宝或者计算机等昂贵的物品时，尤其是在节假日或者商铺中售出的物品时，需要多加小心。 Henry: 好的。现在我对进行安全在线支付更加有信心了。非常感谢你们的见议。练习

Unit 5 Section A Software Design （软件设计） Design is defined in [IEEE610.12-90] as both “the process of defining the architecture, components, interfaces, and other characteristics of a system or component ” and “the result of that process.” Viewed as a process, software design is the software engineering life cycle activity in which software requirements are analyzed in order to produce a description of the software ’s internal structure that will serve as the basis for its construction. More precisely, a software design (the result) must describe the software architecture -- that is how software is decomposed and organized into components -- and the interfaces between those components. It must also describe the components at a level of detail that enable their construction. Software design plays an important role in developing software: it allows software engineers to produce various models that form a kind of blueprint of the solution to be implemented. We can analyze and evaluate these models to determine whether or not they will allow us to fulfill the various requirements. We can also examine and evaluate various alternative solutions and trade-offs . Finally, we can use the resulting models to plan the subsequent development activities, in addition to using them as input and the starting point of construction and testing. In a standard listing of software life cycle processed such as IEEE/EIA 12207 Software Life Cycle Processes [IEEE 12207.0-96], software design consists of two activities that fit between software requirements analysis and software construction: Software architectural design (sometimes called top level design): describing software ’s top-level structure and organization and identifying the various components. Software detailed design: describing each component sufficiently to allow for its construction.

第4单元操作系统第一部分听力和对话对话：关于操作系统的讨论（Henry想要了解更多有关于操作系统的内容，所以他在课后向Mark和Sophie请教） Henry: 一个操作系统可以实现的确切的功能是什么？ Sophie: 它控制包括视觉体验、键盘、鼠标、麦克风以及触摸屏等搜集用户需求的用户接口的关键因素。 Mark：并且在幕后，操作系统忙碌地监控发生在设备内的操作。 Henry: 我了解诸如Wind ows、iOS等很基础的操作系统，但是我认为还有其他的操作系统有很广泛的用途。 Sophie：你说的很对。操作系统可以根据它们在什么设备上使用来进行分类。 Mark：台式机操作系统是为台式机或者手提电脑而设计。你在学校、在家或在工作中使用的电脑大部分都配置有台式机操作系统，如Microsoft Wind ows，OS X，或者Chrome OS。Sophie：另外，像iOS和Android这样的操作系统被定义为移动操作系统，因为它们被设计用于手机、平板电脑、电子书阅读器。 Henry：还有其他的吗？ Sophie：当然。被部署用于网络、文件、应用、数据库、邮件服务器的电脑通常使用可以被多个用户同时使用的分布式网络的服务器操作系统。 Mark：Linux,、UNIX,、Wind ows和OS X服务器都是流行的服务器操作系统。 Henry：太棒了。操作系统究竟存在于哪里？ Mark：在一些诸如手机、电子阅读器的电子设备中，整个操作系统足够小所以可以被储存在只读存储器中。对于其他大多数的电脑，操作系统很大，所以大部分存储在硬盘上或者固态硬盘上。 Sophie：是的。在引导程序的过程中，操作系统内核被加载至随机存取存储器中。内核提供关键的操作系统服务，如内存管理、获取文件。在电脑运行的过程中，内核一直存在于随机存取存储器中。其他的部分如定制化工具，被需要的时候会加载至随机存取存储器中。Henry：我明白了！十分感谢你们。练习以小组的形式，用右边的其他表达式来替换文中相应的陈述，组成类似的对话。听力理解：安卓安卓是由谷歌和超过30家科技手机公司所组成的开放手机联盟所开发基于Linux的操作系统，是全球范围内使用最广的手机系统。安卓被作为手机设备的基础平台，使得开发者们能够充分利用手机设备能够提供的特性来开发移动应用。因为这是一个开发平台，所以仍和人都能够下载和使用安卓。金冠硬件生产商必须依附某些说明从而能够被称为“安卓兼
