科技英语翻译练习1（共五则）

科技英语翻译练习1（共五则）第一篇：科技英语翻译练习1科技英语翻译练习(1)If you want to spark a heated debate at a dinner party, bring up the topic of genetically modified foods.For many people, the concept of genetically altered, high-tech crop production raises all kinds of environmental, health, safety and ethical questions.Particularly in countries with long agrarian traditions--and vocal green lobbies--the idea seems against nature.如果你想在某次晚宴上挑起一场激烈的争论，那就提出转基因食品的话题吧。

对许多人来说，高科技的转基因作物生产的概念会带来诸如环境、健康、安全和伦理等方面的各种问题。

特别是在有悠久的农业生产传统和主张环保的游说集团的国家里，转基因食品的主意似乎有悖自然。

In fact, genetically modified foods are already very much a part of our lives.A third of the corn and more than half the soybeans and cotton grown in the US last year were the product of biotechnology, according to the Department of Agriculture.More than 65 million acres of genetically modified crops will be planted in the US this year.The genetic is out of the bottle.事实上，转基因食品已经成为我们生活重要的一部分。

科技英语课外练习译成汉语版

P231.Thunderstorms producing large hail are also likely to produce tornadoes.2.Contrary to the opinions of many people , tornadoes are not particularly energetic.3.An average tornado contains much less energy than the thunderstorm that produces it, and is appreciably less energetic than a cyclone.4.But since the energy of a tornado is expended in a short period of time, its power-energy divided by time is relatively high.5.Because of their concentrated power, tornadoes are probably the most feared of all weather phenomena.6.They often strike suddenly, with little warming, and in a few minutes cause extensive damage to property, injuries and loss of lives.7.Tornado may have the appearance of a narrow funnel, cylinder, or rope extending from the base of a thunderstorm to the ground.8.The visible funnel consists mostly of water droplets formed by condensation in the funnel.9. Near the ground blowing dust, leaves and other debris identify the presence of a strong vortex. 10.Tornadoes and weak visible vortex observed over water-most often in the tropics and subtropics are called water spouts.较大冰雹的雷暴也很有可能会形成龙卷风。

信息科技英语翻译之汉译英课外练习（01）因特网搜索工具分为两大阵营：搜索引擎，如HotBot和AltaVista，以及在线目录，如Yahoo和Lycos。

两者间的差别与它们如何编撰网站编目有关。

当然，对任何规律都有例外。

有些搜索实用程序，如Ask Jeeves，把搜索引擎和目录方法合并成单一的软件包，希望把这两个阵营中最好的东西提供给用户。

在基于目录的搜索服务中，Web网站编目是手工编撰的。

• 译文：互联网有很多传输环节，其中干线部分早就采用了高速光纤数据传输，例如海底光缆和高速卫星数据传输系统。现在的瓶颈常常是在用户端，即网民进入因特网入口端，也就是说“最后一英里”。所以宽带接入系统一时成为人们关注的商机。
• 目前，中国的宽带接入技术主要有四种。一是有线电话的同轴电缆光纤混合网技术，二是利用传统电话线不对称数字用户环路技术，三是小区以太技术，四是直接卫星连接技术。
• 例如： • 例1. The testing of machines by this method
entails some loss of power.
• 译文∶用这种方法测试机器会浪费一定的能量。
• 例2. Today the electronic computer is widely used in solving mathematical problems having to do with weather forecasting and putting satellites into orbit.
• 译文：对小于米的单位，十进制是这样应用的：米被分成分米（dm）、厘米（cm）、毫米（mm)等等，使测量变得非常简单。此外， 1000米合成一公里（km），作为用来测量长距离的单位。
• 以上篇章中共出现了四个句子，其中前三个句子采用了被动语态（算上第三句中的which引导的非限定性定于从句）。在翻译成汉语时需要作必要的调整，一般情况下要用主动语态结ቤተ መጻሕፍቲ ባይዱ进行翻译。该译文如下：

What Is Electricity?The last two chapters have described some of the ways in which electricity behaves, without saying what it is. 以上两章讲述了电的一些活动特性 , 但并没有说明电究竟是什么。

To most people electricity is a rather mysterious thing, perhaps because it is a silent and invisible ---- almost a secret -- agent which we do not know in the direct way we know things that we can see and touch. 对大多数人来说电是一种很神秘的东西 , 这大概由于它是一种无声、无形 , 几乎是神出鬼没的物质 , 我们无法想象了解那些看得见、摸得着的东西那样 , 去直接地了解它。

But everyone of the many thousands of different materials in the world contains hidden electricity. 但在世间成千上万种不同的物质中又无一不包含着潜在的电。

All materials are made fromdifferent simple substances called "elements".一切物质都是由一些各不相同被称为 " 元素 " 的简单物质构成的。

口译二级实务信息科技练习试卷2(题后含答案及解析) 题型有：1. English-Chinese TranslationPART 1 English-Chinese Translation (50 points, 30 minutes)Interpret the following passages from English into Chinese. Start interpreting at the signal and stop it at the signal. You may take notes while you are listening. You will hear the passages only ONCE. Now let’s begin.1．In order for people to make the most of the Information Society, they must have enhanced levels of ICT literacy and ICT skills. To achieve this, relevant education and training should be promoted at every level, from primary to adult, to open up opportunities for as many people as possible, and especially for the disadvantaged. The capacity of developing and least developed countries to apply ICTs effectively must be enhanced through regional and international cooperation. // ICTs can contribute to enhancing the quality of teaching and learning, and the sharing of knowledge and information. Teachers act as a gateway to the Information Society, and their skills development and curriculum resources need increased support. // It is also important to improve both basic and advanced education in science and technology. This will help to create a critical mass of highly qualified and skilled ICT professionals and experts that will continue to serve as a foundation for the region’s ICT development. It is recognized that education in network infrastructure development and operation is of particular importance, and is critical to the availability of efficient, reliable, competitive and secure ICT network services. // The transition to the Information Society requires the creation of appropriate and transparent legal, regulatory and policy frameworks at the global, regional and national levels. These frameworks should give due regard to the rights and obligations of all stakeholders in such areas as freedom of expression, privacy, security, management of Internet addresses and domain names, and consumer protection, while also maintaining economic incentives and ensuring trust and confidence for business activities. In order to secure prompt settlement of disputes, Alternative Dispute Resolution (ADR) should be considered along with normal judicial proceedings. // While intellectual property rights play a vital role in fostering innovation in software, ecommerce and associated trade and investment, there is a need to promote initiatives to ensure fair balance between IPRs and the interests of the users of information, while also taking into consideration the global consensus achieved on IPR issues in multilateral organizations. // Copyright holders and distributors of content should be cognizant of the need to ensure that content is accessible for all, including persons with disabilities. In this connection, access requirements should be included in legal, regulatory and policy frameworks, where appropriate. // Among the challenges to the region are the general lack of awareness of information security issues, the rapidly evolving complexity, capacity and reach of information technology, the anonymity offered by these technologies, and the transnational nature of communicationframeworks. // Recognizing the principle of fair, equitable and appropriate access to ICTs for all countries, special attention should be paid to the fact that ICTs can potentially be used for purposes that are inconsistent with the objectives of maintaining international stability and security, and may adversely affect the integrity of the infrastructure within States, to the detriment of their security in both civil and military fields. // A multi-pronged approach is needed to address these challenges, and cybercrime, on all fronts, with emphasis on preventive approaches, national guidelines and regional and international cooperation. At the same time, action to address cybercrime and to ensure a safe and secure Information Society must respect the sovereignty of nations and maintain respect for the constitutional and other rights of all persons, including freedom of expression. // All stakeholders concerned with ICT issues should take the necessary steps to enhance security, user confidence and other aspects of information and system/network integrity in order to avoid the risk of wholesale disruption and destruction of the network systems on which they are increasingly dependent. // Effective information security could be guaranteed not only by technology, but also by education and training, policy and law, and international cooperation. In the long term, development of a “global culture of cyber-security”, based on a common understanding of regulations and appropriate mechanisms for information and technology exchange and international cooperation. should be promoted. // (Excerpt from “The Tokyo Declaration—the Asia-Pacific perspective to the WSIS”)正确答案：要充分利用信息社会，就必须提高人们掌握信息通信技术的知识水平和技能。
