高速通讯肯定会对作曲者产生影响。如今各种风格如此快速地为人所了解和模仿，“风格跨越”可能成为新世纪里音乐界的时髦词。人们可以在家里下载任何作品。昨天地球另一边的人作了什么，明天你就可以知道。古典音乐，爵士乐和其他音乐形式之间的屏障将会继续崩溃，听众将会从许多不同风格的作品中获得同样的快感。可以预见，人们的欣赏口味将会更加多元化。一个很大的未知数是，新技术对音乐的音响效果而不是其形式和结构会产生什么影响。本世纪我们已经看到打击乐在管弦乐作品中的潜力发挥到了令人无法辨认的程度，而且我们也已习惯了电子音乐。因此可以预见，未来的发展不久就会给我们所听到的音乐带来巨大变化。The speed of communication is bound to have an effect on composers——styles are now known and imitated so quickly that “crossover” may be the buzzword for music in the new century. People can download anything in their home, and you know tomorrow what someone on the other side of the world did yesterday. Barriers between classical music, jazz and other forms will continue to break down and audiences will derive equal pleasure from lots of different styles. I foresee a greater plurality of taste. The great unknown is the effect new technology is going to have on the soundworld of music, as opposed to its forms and structures. In this century we have seen the potential of percussion in orchestral work develop out of all recognition, and have become accustomed to electronic music. So I anticipate developments around the corner that will produce huge changes in what we listen to.

浅谈中国菜名的翻译 我国悠久的历史和广袤的国土孕育了中国独特的烹饪艺术和丰富的饮食文化。我们国家也以几千年的饮食文化文明于世。随着我国经济飞速发展，与国外交流日益增多，餐饮业也面临着走向世界的机遇和挑战。中国菜名是汉语语汇中承载中国文化最多的语汇之一, 不仅承载着几千年来的中国饮食文化, 还承载着大量的非饮食文化, 如神话、民俗、历史、文学、宗教信仰等等, 在菜名所传达的表层语义背后有着更为深厚复杂的多元文化元素。同时由于饮食与文化的密切联系，这些都大大增大了翻译的难度。 1.首先我们来看一下一些我们常见的错误翻译 长期以来，菜名的翻译没有统一的标准，加上译者水平有限和地域差异，并不了解菜式的内涵，致使很多菜名的翻译让人感到不知所云。比如口水鸡slobbering chicken、童子鸡chicken without sexual life、夫妻肺片the couple’s lung 等，这翻译让外国人看了都吓跑了，哪里还有食欲吃饭呢？再如东坡肉poet Dongpo’s braised pork，东坡肉是用蒸的方法做出来的，所以这里应该为Poet Dongpo’s steamed pork 而不是用braised；“鱼香肉丝”较常见的有两种译法，另外也有人译为shredded pork with garlic sauce，前者译法为直译，后者加了简单的解释，虽然看似简单易懂，很直观，但是译者没有弄清楚此菜的配料，川菜口味浓重，很多菜肴的配料都是少不了“川菜之魂”郫县豆瓣酱，鱼香肉丝正是用到此配料，是不用所谓的大蒜酱，所以后者翻译存在误的地方；水煮鱼，也是川菜中的代表作，又麻又辣，有译者翻译为tender stewed fish，这个译法不够全面，应该在后面加上in chili sauce；夫妻肺片译为pork lungs in chili sauce，这个译法的译者应该不明白此菜的来历和主料，夫妻肺片根本不是用猪肺做成的，而且和肺一点都不沾边，此菜的主料都是用牛内脏，所以这个译发讲不通。对于以上的翻译错误我们不能只是一笑而过，我们应该感受到菜名翻译的难度，从而思考怎样才能更好的翻译来达到最佳的效果。

专业英语大作业 一：英译汉 翻译范围TCP/IP Illustrated, V olume 1: The Protocols 5.1~5.5 15.1~15.2 第5章RARP：逆地址解析协议 5.1简介 5.2 RARP报文格式 5.3 RARP示例 5.4 RARP服务的设计 5.5小结 练习 5.1简介 一个拥有本地磁盘的系统通常是从磁盘文件读取配置文件中获取其IP地址。但一个没有磁盘的系统，如X终端或无盘工作站，需要一些其它方式去获得其IP地址。 每个系统在网络上都有一个唯一的硬件地址，由网络接口的制造商分配。 RARP的原则是无盘系统从接口卡上读取其独特的硬件地址，并发送RARP请求（网络上的广播帧）要求别人对无盘系统的IP地址（使用RARP回应）进行应答。 虽然这个概念很简单，执行往往比ARP更难，在本章后面会描述其原因。 RARP的正式规范是RFC 903。 5.2 RARP报文格式 RARP报文的格式几乎与ARP报文是相同的（图4.3）。唯一的区别是，RARP 的请求或应答帧类型为0×8035，并且在操作层RARP请求值为3、RARP应答值为4。 图4-3 ARP在网络上请求与应答报文的格式 与ARP一样，RARP服务器请求是广播和RARP应答通常是单播。 5.3 RARP示例 在我们的网络，我们可以强制sun主机从网络引导，而不是它的本地磁盘。 如果我们在主机bsdi上运行RARP服务器和tcpdump，我们得到如图5.1所示的输出。我们使用-e参数去标记tcpdump的打印硬件地址：

图5.1 RARP请求和应答。 该RARP请求是广播（1号线）的，第2行的RARP应答是单播的。第2行的输出，“at sun”,意味着RARP应答包含了主机sun（140.252.13.33）的IP地址。 在第3行，我们看到，一旦sun接收其IP地址，它会发出一个TFTP读请求（RRQ）的文件8CFCOD21.SUN4C。（TFTP是简单文件传输协议，我们在第15章进行详细描述）。在文件名中的8个十六进制数字是sun主机的IP地址140.252.13.33的十六进制表示形式。这是在RARP应答中返回的IP地址。该文件名的其余部分，后缀SUN4C表示系统正在引导的类型。 Tcpdump表示第3行是一个长度为65的IP数据报，而不是一个UDP数据报（实际上它确实是），因为我们运行tcpdump命令使用-e参数，看硬件级别的地址。另一点，在图5.1要注意的是在第2行的以太网帧的长度似乎比最小较短（我们所说的是在4.5节60字节）。原因是我们的系统，该系统上运行的tcpdump 发送该以太网帧（BSDI）。该应用程序rarpd，写42字节到BSD分组过滤器装置（14字节的以太网报头和28字节的RARP应答），这是什么的tcpdump收到的副本。但以太网设备驱动程序垫这个短帧的最小尺寸为传输（60 ）。如果我们在另一个系统上已经运行的tcpdump ，长度会是60。 我们可以看到在这个例子，当这种无盘系统接收在RARP应答它的IP地址，它会发出一个TFTP请求来读取一个引导映像。在这一点上，我们不会进入其他详细介绍无盘系统是如何引导自己。（第16章介绍了使用RARP ，BOOTP和TFTP无盘X终端的引导顺序。） 图5.2表示出了如果有在网络上没有RARP服务器所得到的数据包。每个数据包的目的地址为以太网的广播地址。以太网地址跟随的是目标硬件地址，并按照发送端的硬件地址发送。

Analog computers are analog devices. That is, they have continuous states rather than discrete numbered states. An analog computer can represent fractional or irrational values exactly, with no round-off. Analog computers are almost never used outside of experimental settings. 模拟计算机是模拟设备。也就是说，他们是连续状态而不是离散的有限状态。一个模拟计算机可以精确代表小数或无理数，没有舍入。模拟计算机几乎从不被使用在实验设置以外。 A processor typically contains an arithmetic/logic unit (ALU), control unit( including processor flags, flag register, or status register), internal buses, and sometimes special function units( the most common special function unit being a floating point unit for floating point arithmetic). 一个处理器通常包含一个算术/逻辑单元（运算器），控制单元(包括处理器标志，标志寄存器，或状态寄存器)，内部总线，有时特殊功能单元(最常见的特殊功能单元作为一个浮点单元用于浮点运算)。 CISC stands for Complex Instruction Set Computer. Mainframe computers and minicomputers were CISC processors, with manufacturers competing to offer the most useful instruction sets. Many of the first two generations of microprocessors were also CISC. CISC代表复杂指令集计算机。大型计算机和小型计算机是CISC处理器，与制造商竞争提供最有用的指令集。微处理器的前两代中许多也是CISC。 Lesson 2 Supercomputer is a broad term for one of the fastest computers currently available. Supercomputers are very expensive and are employed for specialized applications that require immense mounts of mathematical calculations (number crunching). 超级计算机是一个广泛的术语，因为它是目前可用的最快的计算机之一。超级计算机是非常昂贵的，并且它被用于需要大量的数学计算（数字运算）的专门应用。 It is a midsize computer. In the past decade, the distinction between large minicomputers and small mainframes has blurred, however, as has the distinction between small minicomputers and workstation. But in general, a minicomputer is a multiprocessing system capable of supporting up to 200 users simultaneously. 它是一个中型计算机。在过去的十年中，大的小型机和小的大型机之间的区别已经模糊，然而，有小的小型机和工作站之间的区别。但在一般情况下，一个小型机是一个能够同时支持多达200个用户的多处理系统。 Workstations generally come with a large, high-resolution graphics screen, a large amount of RAM, built-in network support, and a graphical user interface. Most workstations also have a mass storage device such as disk drive, but a special type of workstation, called a diskless workstation, comes without a disk drive. 工作站一般都配有一个大的，高分辨率的图形屏幕，大量的内存，内置网络支持以及一个图形用户界面。大多数工作站也有一个大容量存储设备如磁盘驱动器，但是一种特殊类型的工作站，被称为无盘工作站，是不带磁盘驱动器的。

E-commerce (electronic commerce or EC) is the buying and selling of goods and services on the Internet, especially the World Wide Web. In practice, this term and a newer term, e-business, are often used interchangably. For online retail selling, the term e-tailing is sometimes used. 电子商务（电子商务或电子商务）是购买和出售的商品和服务在互联网，特别是万维网上的。在实践中，这项和一个新的术语，电子商务，往往交替使用。网上零售，电子零售的术语有时用。 E-tailing or The Virtual Storefront and the Virtual Mall 网上或虚拟商店和虚拟商店 As a place for direct retail shopping, with its 24-hour availability, a global reach, the ability to interact and provide custom information and ordering, and multimedia prospects, the Web is rapidly becoming a multibillion dollar source of revenue for the world's businesses. A number of businesses already report considerable success. As early as the middle of 1997, Dell Computers reported orders of a million dollars a day. By early 1999, projected e-commerce revenues for business were in the billions of dollars and the stocks of companies deemed most adept at e-commerce were skyrocketing. Although many so-called dotcom retailers disappeared in the economic shakeout of 2000, Web retailing at sites such as https://www.sodocs.net/doc/6112122128.html,, https://www.sodocs.net/doc/6112122128.html,, and https://www.sodocs.net/doc/6112122128.html, continues to grow. 作为一个直接的零售购物，其24小时供应，全球性的，互动的能力，并提供自定义信息和订购，和多媒体，网络正在迅速成为一个数十亿美元的收入来源，为全球的企业。一些企业已报告了相当大的成功。早在1997年年中，戴尔电脑报告的订单一百万美元一天。1999年初，预计的电子商务业务收入都在数十亿美元的股票和公司认为最善于电子商务暴涨。虽然许多所谓的互联网零售商消失在经济衰退2000，网上零售网站如https://www.sodocs.net/doc/6112122128.html,，https://www.sodocs.net/doc/6112122128.html,，和https://www.sodocs.net/doc/6112122128.html,继续增长 Market Research 市场研究 In early 1999, it was widely recognized that because of the interactive nature of the Internet, companies could gather data about prospects and customers in unprecedented amounts -through site registration, questionnaires, and as part of taking orders. The issue of whether data was being collected with the knowledge and permission of market subjects had been raised. (Microsoft referred to its policy of data collection as "profiling" and a proposed standard has been developed that allows Internet users to decide who can have what personal information.)

NNCE Book3课后翻译参考答案 Unit1 英译中原文：Global citizen is someone who identifies with being part of an emerging world community and whose actions contribute to building this community's values and practices. Global citizenship believes that humankind is essentially on and each individual has the power to change things. In our interdependent world, global citizenship encourages us to recognize our responsibilities toward each other and learn from each other. Global citizens care about education, disease, poverty, and environmental issues around the world. Today, the forces of global engagement are helping some people identify themselves as global citizens who have a sense of belonging to a world community. This growing global identity in large part is made possible by the forces of modern information, communications and transportation technologies. Global citizenship aims to empower people to lead their own action. Along with the knowledge and values that they have gained from learning about global issues, people need to be equipped with the necessary skills to give themselves the ability and confidence to be pro-active in making a positive difference in the world.

Strength is one of the important properties of metals .It enables them to resist external loads without incurring structural damages.Metals, possessing toughness, a property of absorbing considerable energy before fracture,bend rather than break. Another property of metals is elasticity.Because of their elasticity,metals subjected to an external load are distorted or stained, and return to their original dimensions when the load is released if the load is not too great. Ductility is the capacity of a metal to be permanently deformed in tension without breaking. That is why some metals, such as copper and aluminum, can be drawn erom a large into a smaller diameter of wire.
