[Ex. 5] 新处理器开始IT技术的新时代
New Processors Open New Era of IT Technologies
Last week, Intel introduced to the public in Russia and other CIS countries a family of processors Intel Xeon E5-2600. 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 5] 平板电脑
Tablet Computer
A tablet computer, or simply tablet, is a one-piece, mobile version of a personal computer, primarily operated by touchscreen (the user's finger essentially functions as the mouse and cursor, removing the need for the physical [i.e., mouse & keyboard] hardware components necessary for a desktop or laptop computer; and, an onscreen, hideable virtual keyboard is integrated into the display). Available in a variety of sizes, even the smallest's touchscreens are much larger than those of a smart phone or personal digital assistant. A tablet computer may be connected to a keyboard with a wireless link or a US
B port. Convertible notebook computers have an integrated keyboard that can be hidden by a swivel joint or slide joint, exposing only the screen for touch operation. Hybrids have a detachable keyboard so that the touch screen can be used as a stand-alone tablet. Booklets include dual-touchscreens, and can be used as a notebook by displaying a virtual keyboard in one of them.
Notes:
cursor [?k?:s?] n. 光标 swivel [?swiv?l] n. 旋轴；旋转接头detachable [di?t?t??bl] adj. 可拆开的 stand-alone adj. 独立运行的
hybrids= hybrid computer混合计算机 booklet [?buklit] n. 笔记本式平板电脑
平板电脑，也叫平板，是个人计算机的一款，可移动，是一个整体。平板电脑主要依靠触屏操作（用户的手指发挥了鼠标和光标的作用，替代了台式和膝上电脑必须的物理硬件[即鼠标和键盘]。还有一个与显示器整合的可隐藏的屏幕虚拟键盘）。平板电脑型号多种，即使是最小的触屏也比智能手机或个人数字助理的屏幕大多了。可以用无线连接或USB插口给平板电脑连接一个键盘。可旋转笔记本电脑可以通过一个旋转铰链或一个滑动铰链把集成的键盘隐藏起来，仅仅在需要触摸时显示。混合型计算机配有一个可拆分的键盘，这样触屏可以当作一个单独的平板电脑使用。笔记本平板电脑包括两个触屏，在其中一个触屏上显示虚拟键盘就可以作为笔记本使用。

Bus Systems Supporting Multiple Peripherals
As the number of potential peripherals grew, using an expansion card for every peripheral became increasingly impossible. This has led to the introduction of bus systems designed specifically to support multiple peripherals. Common examples are the SATA ports in modern computers, which allow a number of hard drives to be connected without the need for a card. However, these high-performance systems are generally too expensive to implement in low-end devices, like a mouse. This has led to the parallel development of a number of low-performance bus systems for these solutions, the most common example being Universal Serial Bus. All such examples may be referred to as peripheral buses, although this terminology is not universal.
Notes:
1. Serial ATA (SATA) is a computer bus interface for connecting host bus adapters to mass storage devices such as hard disk drives and optical drives.
2. Universal Serial Bus USB
支持多种外接设备的总线系统
随着外接设备数量的不断增加，想用扩展卡来应付每一种外围设备越来越不现实了，这就产生了设计专门支持多种外接设备的总线系统。通常的例子就是现代计算机上的SATA接口，这就允许很多硬盘驱动器不需要卡就可以同计算机连接起来。但是把这些高性能系统用于低端设备，如鼠标等就很不合算。这就导致同时开发很多低性能的总线系统解决方案，最常见的例子就是UBS接口。所有这些例子都可以称作外接设备总线，尽管这个术语还没有普遍通用。

USB flash drive
A US
B flash drive is a data storage device that includes flash memory with an integrated Universal Serial Bus (USB) interface. USB flash drives are typically removable and rewritable, and physically much smaller than a floppy disk. Most weigh less than 30 g. As of September 2011, drives of up to 256 gigabytes (GB) are available. Storage capacities as large as 2 terabytes are planned, with steady improvements in size and price per capacity expected. Some allow up to 100,000 write/erase cycles, depending on the exact type of memory chip used, and a 10 year shelf storage time.
USB flash drives are often used for the same purposes for which floppy disks or CD-ROMs were used, i.e., for storage, back-up and transfer of computer files. They are smaller, faster, have thousands of times more capacity, and are more durable and reliable because they have no moving parts. Until about 2005, most desktop and laptop computers were supplied with floppy disk drives, but floppy disk drives have been abandoned in favor of USB ports.
Notes
GB: gigabyte 吉字节 109字节； terabyte TB 太字节，1012字节
USB闪驱
USB闪驱是一种数据存储设备，它包含带有一个集成的通用串行总线（USB）接口。USB
闪驱通常可以移动并可以重写，其尺寸要比软盘小得多，大多数的重量不到30克。从2011
年9月始，市场就出现256 GB的U盘。2太字节的U盘在筹划之中，估计U盘大小会更加合理，
价格也更合适。有的U盘允许写/擦10万个循环，这取决于存储芯片的型号，储存寿命可以达
到10年时间。
USB闪驱与软盘或CD-ROM的目的相同，就是为了计算机文件的存储、备份和转移。因为
它们没有移动部件，所以体积更小，速度更快，拥有数千倍的容量，更加持久可靠。到2005年，大部分台式和膝上电脑还都配备软驱，但是软驱因为USB插口而被淘汰。

Electroluminescent Display（电致发光显示器）
A type of flat-panel display（平板显示）that uses the property of electroluminescence, whereby a phosphor will emit photons of radiation（光子辐射）when placed in an electric field（电场）. The phosphor is incorporated in a thin coating on the screen; an additional coating can produce full color. Electroluminescent screens are used in some large-screen displays, such as airport announcement boards. Nowadays electroluminescent screens are mainly used for small displays in control panels and domestic equipment.

Digital Technology of Copy Machine
There is an increasing trend for new photocopiers to adopt digital technology, thus replacing the older analog technology. With digital copying, the copier effectively consists of an integrated scanner and laser printer. This design has several advantages, such as automatic image quality enhancement and the ability to "build jobs" (that is, to scan page images independently of the process of printing them). Some digital copiers can function as high-speed scanners; such models typically offer the ability to send documents via email or to make them available on file servers.
A great advantage of digital copier technology is "automatic digital collation." For example, when copying a set of 20 pages 20 times, a digital copier scans each page only once, then uses the stored information to produce 20 sets. In an analog copier, either each page is scanned 20 times (a total of 400 scans), making one set at a time, or 20 separate output trays are used for the 20 sets.
Notes:
scanner 扫描仪 collation [k??lei?(?)n] n. 校勘，核对 tray 托盘，文件盘
复印机的数字技术
新的复印机越来越趋向于采用数字技术替代老的模拟技术。数字复印机有效地把扫描仪和激光打印机整合在一起，这种设计拥有数个优势，譬如自动图形质量提高，自动工作的能力（扫描和打印互不干涉）。有些数字复印机如同一个高速扫描仪，这样的型号通常具有通过email发送文件的能力，或者给文件服务器提供文件。
数字复印机的最大优点在于它可以“自动数字校验”。例如当要复印20页，每页复印20份的时候，数字复印机只需每一页扫描一次，然后使用储存的信息复印20份。如果是模拟复印机，要么每一页都要扫描20次（一共要扫描400次），一次复印一份；要么每页复印20份，20页分别放在20个输出托盘中。

Smartphone
To really understand what a smartphone is (and is not), we should start with a history lesson. In the beginning, there were cell phones and personal digital assistants (or PDAs). Cell phones were used for making calls--and not much else--while PDAs, like the Palm Pilot, were used as personal, portable organizers.
A PDA could store your contact info and a to-do list, and could sync with your computer.
Eventually, PDAs gained wireless connectivity and were able to send and receive e-mail. Cell phones, meanwhile, gained messaging capabilities, too. PDAs then added cellular phone features, while cell phones added more PDA-like (and even computer-like) features. The result was the smartphone.
智能手机
要真正理解什么是智能手机，什么不是智能手机，我们应该从了解历史开始。起初人们使用手机和个人数字助理。手机只是用来打电话，而数字助理，如掌上电脑，是个人便携式的记事本。一台个人数字助理能储存你的联系信息以及将要处理的事情，可以和电脑同步。
最终，个人数字助理开始了无线连接，能够发送和接收电子邮件，而手机也具备了获取信息的能力。个人数字助理添加手机功能，手机也增添个人数字助理（甚至计算机）的特性，其结果就是智能手机。

What does HTML stand for?
HTML is an abbreviation of "HyperText Mark-up Language" - which is already more than you need to know at this stage. However, for the sake of good order, let us explain in greater detail.
?Hyper is the opposite of linear. In the good old days - when a mouse was something the cat chased - computer programs ran linearly: when the program had executed one action it went to the next line and after that, the next line and so on. But HTML is different - you can go wherever you want and whenever you want. For example, it is not necessary to visit https://www.360docs.net/doc/1b1375808.html, before you visit https://www.360docs.net/doc/1b1375808.html,.
?Text is self-explanatory.
?Mark-up is what you do with the text. You are marking up the text the same way you do in a text editing program with headings, bullets and bold text and so on.
?Language is what HTML is. It uses many English words.
HTML代表什么？
HTML是HyperText Mark-up Language（超文本表示语言）的缩写形式，这超出现阶段你应该知道的内容。但是为了有一个好的学习的顺序，我们还是详尽解释一下为好。
Hyper与线性相反。很早的时候，老鼠是猫追逐的对象——计算机程序为线性运行：当程序执行了一个动作，就移动到下一行，然后再下一行等等。但是HTML不一样了，你可以在任何时候到你想去的任何地方。例如你没有必要在访问https://www.360docs.net/doc/1b1375808.html,前先访问https://www.360docs.net/doc/1b1375808.html,网站。
Text 是自我解释性的。
Mark-up就是处理文本，就如同在文本编辑程序中做标题，添加黑圆点，加粗等一样给文本添加标识。
Language就是HTML。它使用许多英语单词。

1. 网站主人使用robots.txt文件给网络机器人（web robots）就自己的网站的访问权
限下达指令，这就是机器人排除协议。
工作的过程如下：机器人想访问一个网站网址，譬如https://www.360docs.net/doc/1b1375808.html,/welcome.html，访问前它首先检查里边的robots.txt，即https://www.360docs.net/doc/1b1375808.html,/robots.txt，发现：User-agent:*（用户代理：*）
Disallow:/ （不准，不接受）
User-agent:*（用户代理：*）的意思是这部分可以适合所有的机器人。Disallow:/ （不准，不接受）告诉机器人，这个网站的任何网页都不允许访问。
在使用robots.txt的时候有两件重要的事情必须想到：
●机器人可以忽略你的robots.txt，尤其是恶意机器人，专门寻找网络的安全漏
洞；还有垃圾邮件散发者使用的email地址收集器根本就不把robots.txt的指令
放在眼里。
●robots.txt文件是公开提供的，任何人都能看到你的服务器的哪些部分你是拒
绝机器人访问的。
因此不要指望robots.txt文件来隐藏信息。
2. 使用And，Or和Not（布尔算子）
本页的例子讲解了布尔算子Or，And和Not（或and not）在索引、数据库和支持布尔类型搜索的搜索引擎中的使用。
想象你由于布置作业，需要找到几本有关爵士乐曲或布鲁斯音乐书籍。在集中注意爵士和布鲁斯音乐的某个方面之前，想了解这方面的一个概括，你在期刊索引中击入三个关键搜索词：
jazz OR blues（爵士或布鲁斯）
这次搜索找到的是讨论爵士或布鲁斯音乐的文章。
Or总是扩大搜索范围。
jazz AND blues（爵士和布鲁斯）
这次搜索找到的是有关爵士音乐和布鲁斯音乐比较的文章。
And总是缩窄了搜索的结果。
jazz NOT blues （爵士不是布鲁斯）
这次搜索只有关于爵士音乐的文章。
Not总是排除指定项目的记录。
注意：在图书目录中，击入jazz AND NOT blues（爵士而不是布鲁斯）

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.360docs.net/doc/1b1375808.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.

D Original Roadrunner On the current TOP 500 list of worldwide supercomputers released in June 2008, Roadrunner, IBM's new super computer, is rated No.1, exceeding IBM Blue Gene, the former No.1 on the list. IBM calls Roadrunner the world’s first “hybrid” supercomputer. It combines 12,960 IBM Cell chips, which power Sony's PlayStation 3 video game machine, with 6,948 dual-core AMD Opteron chips and 80 terabytes of memory. It runs Red Hat Linux. Roadrunner is billed at the fastest in the world, operating at one petaflop or one thousand trillion calculations per second. So, exactly how fast is the supercomputer? IBM said the speed is roughly equivalent to the combined computing power of 100,000 of today's fastest laptop computers - users would need a stack of laptops 1.5 miles high to match Roadrunner's performance. It would also take the entire population of the earth - about 6 billion people - each working a handheld calculator at the rate of 1 second per calculation more than 46 years to do what Roadrunner can do in one day. IBM said that in the past 10 years, supercomputer power has increased about 1,000 times. Today, just three of Roadrunner's 3,456 tri-blade units have the same power as the 1998 fastest computer. Now, a complex physics calculation that will take Roadrunner one week to complete would have taken the 1998 machine 20 years to finish.

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
