1、The multinational is big and rich. It often operates in industries which are difficult to enter and of vital national importance, e.g. the computer, chemical and automobile industries. Most important of all, the main objective of the multinational is to organize its activities around the world so as to maximize global profits and global market shares. Each subsidiary is part of an international network of affiliates. These all interact with each other. Each part serves the whole. The center controlling the network—the multinationals’ headquarters—is not under the control of the host government. It is frequently thousands of miles away from these subsidiaries.
跨国公司不仅大而且富有。它往往经营一些全国性的难以进入的至关重要的行业，例如计算机，化工，汽车等行业。最重要的是，跨国公司的主要目的是组织世界各地的活动，以最大限度地提高全球利润和全球市场份额。每一附属子公司都是国际网络的一部分。这些都互相影响，部分服务于整体。跨国公司的总部是控制网络的中心，千里之外的这些子公司是不受东道国政府的控制。
2、Right now the world is focused on e-commerce. The invention of the Web has seen new companies grow at an astonishing rate. It brings rapid rewards to people with imagination and new ideas. Sometimes it seems like millionaires who are created overnight.
现在的世界是专注于电子商务的。网络的发明者已经看到新公司以惊人的速度增长。人们的想象与新的理念给它带来了快速回报。有时就好像在一夜之间创造了百万富翁。
3、Most Internet searches are through search engines, giant computers which crawl the web looking for information. Some search engines have become “portal companies”. These give people the chance to have the information they need delivered to them with out wasting ti me searching for it. Managers can keep on top of news about their industry and monitor stock prices and their competitors’ activities. More junior staff can discover all they need to know about their jobs.
用计算机进行检索网页，寻找信息时，大多数互联网搜索是通过搜索引擎。一些搜索引擎已经成为“门户公司“。这些让人们有机会得到他们需要的信息又不浪费时间寻找。管理人员可以保持最高的行业新闻，监控股票价格或者其竞争对手的活动。更多初级员工可以找到所有他们工作需要知道的信息。
4、One of the key factors for advertising success is product differentiation. In other words, there needs to be a clear difference between what you sell and what your competitors offer. Produce wholesalers, for example, do not need to advertise their potatoes or tomatoes to restaurants because most wholesalers sell similar grades and quality of products. But if one wholesaler has a demonstrable difference, such as guaranteed fast delivery or lower prices, that is another matter. Advertising works best when a business has a competitive advantage that it wants to communicate to customers. This advantage might be superior service, lower prices, or higher quality. Sometimes a business may have an important feature that competitors have as well, but if no one has advertised it, the first business that does can gain an advantage.
广告成功的关键因素之一是产品差异化。换句话说，你和你的竞争对手卖什么需要有明确的区别。例如，当大多数批发商出售类似的产品档次和质量时，生产批发商不需要对购买他们的土豆或西红柿的餐馆做广告。但是，如果一个批发商有明显差异，例如保证快速交货或更低的价格，那就是另一回事。当把一个企业具有的竞争优势传达给客户的时候，广告就达到了效果。这种优势可能是优质的服务，更低的价格，或更高的质量。有时，一个企业可能有一个重要特点，竞争对手也一样，但如果没有人做广告，做第一个业务就是优势
5、It cannot be denied that insurance in capitalist countries is useful to both industrial and commercial sectors, in that all such branches being operated with private capital, investors can ill afford any major loss of, or to, their interests. Production or business activities would be at a standstill if such interests were not protected by insurance. If a key branch is involved, other related branches may also be affected. Individuals also find insurance of use to them as this is the only way in which they can be protected financially.
不能否认，在资本主义国家的工业和商业部门保险是非常有用的，在所有这些部门或者私人资本运营，投资者经受不起任何重大损失，或向他们的利益。如果这些利益没有受到保险保障，生产经营活动将处于停滞状态。如果涉及的一个重要分支，其他相关部门也可能受到影响。个人也觉得一定要使用保险，因为这是他们可以得到的保护经济的唯一的方式。
6、The primary function of advertising is to communicate marketing objectives to selected target audience. It is used to accomplish a number of tasks, using different media vehicles, reaching diverse audience, and gaining interest with a number of creative approaches.
However, despite the seemingly endless channels for using advertising, it is basically a marketing communication tool. When we examine unsuccessful advertising activities, we often find that advertising was used to accomplish inappropriate tasks. Successful advertising must be aimed for specific objectives. Before we can determine advertising objectives, it is advisable to distinguish between marketing and advertising goals.
广告的主要功能是传达的营销目标，选择的目标受众。它是用来完成一些任务，使用不同的媒介，达到不同的受众，并取得了创造性的办法的兴趣。然而，尽管使用看似无休止的广告渠道，它基本上是一种营销沟通工具。当我们研究成功的广告活动中，我们常常发现，广告是用来完成不恰当的任务。成功的广告的目的必须是为特定的目标。在我们能够确定广告目标，最好是把市场营销和广告目标区分开
7、In most economic systems, the prices of the majority of goods and services do not change over short period of time. In some systems it is of course possible for an individual to bargain over prices, because they are not fixed in advance. In general terms, however, the individual cannot change the prices of the commodities he wants. When planning his expenditure, he must therefore accept these fixed prices. He must also pay this same fixed price no matter how many units he buys. A consumer will go on buying bananas for as long as he continues to be satisfied. If he buys more, he shows that his satisfaction compensates less for the loss of money.
在大多数经济制度中，大多数商品和服务的价格不会在很短的时间改变。在某些系统中，当然可以为个人对价格进行谈判，因为他们没有事先确定。但是，在一般条款中，在规划自己的开支时，个人不能改变他要的商品价格。因此他必须接受这些固定价格。无论他买多少个单位，他必须付出相同的固定价格。只要能够得到满足，消费者会继续购买。如果他买更多，就表明，他满意产品的价格
8、In the entrepreneurial world, no one strives for infallibility like French chefs. Many of them, entrepreneur owners of inns and restaurants, they cater to a market consisting of the planet’s meanest and most persnickety customers. Armed with razor-sharp palates and wagging tongues, food critics, politicians, and travelers from all over the world flock to French eateries. Even when they love the chow, these customers from hell are quick to denounce it in public if they aren’t 100% pleased. And the most feared diners of all are the humorless and often anonymous agents of Guide Michelin, whose rarely bestowed three-star rating is the most coveted award in cuisine. 在创业的世界中，没有人像法国的厨师那样求无错。他们当中很多企业家像旅馆和餐馆业主，组成的地球最卑鄙、最挑剔的客户市场。手持锋利的武器的美食评论家、政治家和来自世界各地的游客涌向法国的食肆。即使他们爱议员，如果他们不是100%的满意，这些客户会快速公开谴责。食客是最可怕的米其林指南，其很少赐予三星级的是最令人垂涎的美食奖项的幽默感，经常匿名代理。

英语作业及答案
下面的范文中有很多错误，请找出形容词与副词的混淆、冠词的遗漏和误用、介词和代词的误用等错误，并检查句子的完整性、单词拼写、主谓的一致性、动词和现在分词是否混淆、复数形式、动词的时态、词汇选择、词性、单词的顺序等问题。 (几乎每个句子都有错误) An university education is a goal of many high school students. Some students want to go into a profession that requires an university degree. But there are other professions that do not require a degree, but require certification from a technological college. The reasons why students make decisions to go to technical college instead of university probably have a lot to do with their choice of career, their own academic abilities and their financial situation. First of all, students make their choices for post-secondary education based on the fields that interest them. A student who is interested in medicine might decide to university, into a pre-med program to prepare to become a doctor, or they might go to nursing school or a nursing program in a technical college. Some career choices offer a choice of educational route. The university route is usually more intense and takes longer. For example, an interior designer might take a one or two year program at a college, or choose to do the degree program as a part of the architectural department at a university. Other career choices involve certification that is available at a college, like broadcast journal or

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。

《自动化专业英语》翻译大作业 所选文字出处：选自论文《PLC的发展和应用》 班级：学号：姓名：成绩： PLC全名为可编程控制器，定义是种数字运算操作的电子系统，专为在工业环境应用而设计的，主要结构由电源，中央处理单元，存储器，输入输出接口电路，功能模块，通信模块组成。PLC具有通用性强、使用方便、适应面广、抗干扰性强、编程简单等特点，在军事、国防、航空航天、交通、工业生产中的地位，在可预见的将来中是无法取代的。PLC有很多流派，我国的PLC研发、生产和应用发展很快，尤其在应用方面更为突出。 PLC的发展历程和主要流派 在工业生产过程中，大量的开关量顺序控制，它按照逻辑条件进行顺序动作，并按照逻辑关系进行连锁保护动作的控制，及大量离散量的数据采集。传统上，这些功能是通过气动或电气控制系统来实现的。1968年美国GM（通用汽车）公司提出取代继电气控制装置的要求，第二年，美国数字公司研制出了基于集成电路和电子技术的控制装置，首次采用程序化的手段应用于电气控制，这就是第一代可编程序控制器，称Programmable Controller（PC）。个人计算机（简称PC）发展起来后，为了方便，也为了反映可编程控制器的功能特点，可编程序控制器定名为Programmable Logic Controller（PLC），现在，仍常常将PLC简称PC。PLC的定义有许多种。国际电工委员会（IEC）对PLC的定义是：可编程控制器是一种数字运算操作的电子系统，专为在工业环境下应用而设计。它采用可编程序的存贮器，用来在其内部存贮执行逻辑运算、顺序控制、定时、计数和算术运算等操作的指令，并通过数字的、模拟的输入和输出，控制各种类型的机械或生产过程。可编程序控制器及其有关设备，都应按易于与工业控制系统形成一个整体，易于扩充其功能的原则设计。上世纪80年代至90年代中期，是PLC发展最快的时期，年增长率一直保持为30~40%。在这时期，PLC在处理模拟量能力、数字运算能力、人机接口能力和网络能力得到大幅度提高，PLC逐渐进入过程控制领域，在某些应用上取代了在过程控制领域处于统治地位的DCS系统。在世界上200多家PLC厂商，400多品种的PLC产品大体可以按地域分成三个流派：一个流派是美国产品，一个流派是欧洲产品，还有一个流派是日本产品。同一地区的产品相互借鉴的比较多，相互影响比较大，技术参透比较深，面临的主要市场相同，拥护要求接近，这一切就使得同一地域的PLC产品表现出比较多的相似性。美国PLC技术的形成与欧洲PLC技术的形成是在相互隔离的情况下，独自研究开发获得的，因此美国的PLC产品与欧洲的PLC产品常表现出来明显的差异性。日本的PLC技术是由美国引进的，因此日本的产品对美国的产品有一定的继承性。世界上比较先进的PLC生产厂家有德国的的西门子、日本的三菱、美国的A-B公司等等。

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/4b13222402.html,, https://www.sodocs.net/doc/4b13222402.html,, and https://www.sodocs.net/doc/4b13222402.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/4b13222402.html,，https://www.sodocs.net/doc/4b13222402.html,，和https://www.sodocs.net/doc/4b13222402.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.)

二0一五年六月 一、英译中(英文科技资料翻译) 原文： An operating system is the software which acts as an interface between a user of a computer and the computer hardware.The purpose of an operating system is to provide an environment in which a user may execute program. The primary goal of an operating system is thus to make the computer system convenient to use. A secondary goal is to use the computer hardware in an efficient way. We can view an operating system as a resource allocator. A computer system has many resources which may be required to solve a problem: CPU time, memory space, , input/output(I/O) devices, and so on.The operating system acts as the manager of these resources and allocates them to specific programs and users as necessary for their tasks. Since there may be many, possibly conflicting, requests for resources, the o/s must decide which requests are allocated resources to operate the computer system fairly and efficiently. Multimedia means, from the user ' perspective, that computer information can be represented through audio and/or video, in addition to text, image, graphics and animation . The integration of these media into the computer provides additional possibilities for the use of computational power currently available (e.g., for interactive presentation of huge amounts of information ). Furthermore, these data can be transmitted though computer and telecommunication networks, which implies applications in the areas of information distribution and cooperative work.Multimedia provides the possibility for a spectrum of new applications, many of which are in place today. A multimedia system distinguishes itself from other systems through several properties. We elaborate on the most important properties such as combination of the media, media-independence, computer control and integration.Not every arbitrary combination of media justifies the usage of the term multimedia. A simple text processing program with incorporated images is often called a multimedia application because two media are processed through one program.But one should talk about multimedia only when both continuous and discrete media are utilized.A text processing program with incorporated images is therefore not a multimedia application. An important aspect of different media is their level of independence from each other. In general, there is a request for independence of different media, but multimedia may require several levels of independence. On the one hand, a computer-controlled video recorder stores audio and video information, but there is an inherently tight connection between the two types of media. Both media are coupled together through the common storage medium of the tape. On the other hand, for the purpose of presentations, the combination of DAT recorder (Digital Audio Tape) signals and computer-available text satisfies the request for media-independence. Early computers were(physically) very large machines run from a console.The programmer would
