GENETICALLY MODIFIED FOODS: Are They Safe?

- Are genetically modified crops an environmental dream come true or a disaster in the making? Scientists are looking for answers

The world seems increasingly divided into those who favor genetically modified (GM) foods and those who fear them. Advocates assert that growing genetically altered crops can be kinder to the environment and that eating foods from those plants is perfectly safe. And, they say, genetic engineering－which can induce plants to grow in poor soils or to produce more nutritious foods－will soon become an essential tool for helping to feed the world's burgeoning population. Skeptics contend that GM crops could pose unique risks to the environment and to health－risks too troubling to accept placidly. Taking that view, many European countries are restricting the planting and importation of GM agricultural products. Much of the debate hinges on perceptions of safety. But what exactly does recent scientific research say about the hazards? The answers, too often lost in reports on the controversy, are served up in the pages that follow.

转基因食品：它们是安全的？-转基因作物环境的梦想或灾难正在形成？科学家们正在寻找答案，世界似乎越来越分为那些喜欢转基因（GM）食品和那些害怕他们。支持者宣称，种植基因改造作物可以有益于环境，食用从这些植物食品是完全安全的。并且，他们说，遗传工程－可诱导植物在贫瘠的土壤中生长出更有营养的食物－将很快成为帮助养活世界不断增长的人口的一个必不可少的工具。怀疑论者声称，转基因作物可能构成了独特的风险，对环境和健康风险－太麻烦接受平稳。以这种观点，许多欧洲国家是限制种植转基因农产品进口。争论大多取决于安全的看法。但它究竟是什么，最近的科学研究说危险吗？的答案，往往迷失在对争议的报告，提供了在接下来的几页。

The authors develop and test a multiclassifier-based near-real-time face detection system based on the premise that a three-part strategy is necessary for designing real-time face detection systems that provide high detection rates. The critical factors for real-time face detection are based on a framework of multiple classification functions: (1) a skin classification function is used as the preliminary stage in order to prune the search, localize the computation, and therefore improve performance time; (2) subsequently, three coarse-to-fine statistical model based classifiers are used to scan the windows and discard most non-face windows; and (3) finally, faces and non-faces are veri??ed from images. The bagging ensemble algorithm (bootstrap aggregating) is also applied to improve the performance of detection rates.

开发和测试一个基于多分类器的近实时的人脸检测系统的基础上，一三部分战略是实时的人脸检测系统，提供高的检出率设计的必要前提。实时人脸检测的关键因素是基于多分类功能的框架：（1）皮肤分类函数为初步阶段修剪搜索，定位计算，从而提高性能；（2）随后，三由粗到细的基于统计模型的分类器进行扫描Windows和丢弃最非人脸窗口；和（3）最后，脸和非面孔验证？从图像？。Bagging集成算法（引导聚合）也被用于提高检测率的性能。

??"The Web" is now so popular it has permeated our everyday life, changing how we stay in touch, share information, complete chores, and even earn an income. A whole new industry has sprung up dedicated to providing new ways to improve productivity, in the process changing how we communicate and allowing us to fit ever more into our ever busier lives.????

Can you use a computer? Can you surf the Internet?I believe that your answer is "yes!'.Now ,most of us can use a computer to surf the Internet . In fact , it's very important for us , we all know that we can do lots of things by surfing the Internet. For example,some students often surf the Internet to find something good for their study , by surfing the Internet,they can learn a lot and make a great progress. When we are free, we often chat with our friends or family members. In the past, if we live very far from our friends or family members we can only write letters to each other, but now Internet can solve this problem ,we can even talk or see each other on computers. Also , we can play games on weekends ,they can help us relax. Of course we can also do many other things on computers. In one word,Internet is really important in our life now.??

In front of the computer, chatting with others. Apparently, they have lost themselves in the virtual cyber world and become slaves to the Internet. Thus, not to strive, not to seize the opportunities, and not to accomplish anything—these things naturally become the creed of many verdant youths. How so? ????Internet, just like drug, cigarette, wine, etc. Its mystery depends on its virtual reality. For instance, when you are chatting with others in the net, identity and appearance mean very little in cyberspace, but your thoughts are really matter. And truly, this “faceless” communication does not create problems. At this moment, rather than reveal your weaknesses，you usually show off your strengths as much as possible. Each netizen wants to do the same thing, then admires each other, and finally they even form the love relationship. However, it is hard to know who the other person really is. But usually he or she cannot make out this point and the couple still misses one another. Once they have met, this will inevitably lead to disappointment. The online boyfriend (girlfriend) you imagine is quite different from the real person. Even that person you are looking forward to seeing is an evildoer unexpectedly. And, quite often, it has no real foundation. Furthermore, what we cannot ignore is that surfing the Internet for a long time every day will cost a lot of money, and it is the reason for many delinquencies. ??

??If you have become an addict, what should you do? It is not a good idea to suddenly go cold turkey. So, you should wean yourself from it gradually. Firstly, you must understand an important point, that is, life in the real world is far richer than anything you will find on a computer screen. Then you should shorten the time spent on the net little by little. Of course, you need self-control and perseverance. The Internet is a double-edged sword. If you make the best of it, you will benefit a lot. Otherwise, it could do great harm to you. ??

On the whole,with the convenience of the Internet, we should carry on using the Internet. But then ,at the same time, we should distinguish whether the information is worth to believe. Only in this way can the Internet performs its best!??

“网络”现在是如此受欢迎,它已经渗透到我们的日常生活中,改变我们如何保持联系,分享信息,完成家务,甚至赚取收入。一个全新的产业已经出现了新的方法致力于提高生产力 ,使我们能够适合进入更加忙碌的生活之中。

你会用计算机吗?你能上网吗?我相信你的答案是“是的!”。现在,我们中的大多数人都能使用电脑上网。实际上,它对我们来说很重要,我们都知道我们上网冲浪能做许多的事情。例如,一些学生在他们的学习中也经常上网去找好东西,通过上网,他们可以学到很多东西,并取得很大的进步。在我们空闲的时候,我们经常与我们的朋友或者家人聊天。在过去,如果我们离朋友或家人非常远时，我们只能写信给对方,但是现在互联网能解决这个问题,我们甚至可以说话甚至能看到对方。同时,我们可以在周末玩游戏,他们能帮助我们放松。当然,我们也可以做许多其他的事。总之,因特网,在我们的生活中是非常重要的。

在电脑前和人聊天。显然,他们在虚拟网络世界中迷去了自己，成为互联网的奴隶。因此,不抓住这个机遇,而不是去完成任何事情自然成为许多人信条。怎么会这样呢?网络,就像毒品、香烟、酒等.它的奥秘取在于它是虚拟现实。举例来说,当你在网上和别人聊天时,身份和外观意味着很小的空间,但你的想法是真的。这种看不到对方的沟通是没问题的。在这时,而不是显示你的弱点,你通常会炫耀你的长处。各位网友想做同样的事情,然后欣赏对方,最后他们甚至形成的爱的关系。然而,很难知道真正的另外的一个人是谁。但通常他或她无法辨认出这一点,这对夫妇还不能见面。一旦他们见面,这将不可避免地失望。网上的男朋友(女朋友)你想象的有很大不同。即使那个人是邪恶。使情况更为糟糕的是, 结果很有可能是太可怕的沉思。并且经常它没有真正的基础。此外,我们不能忽视是上网时间长,每天都花很多钱,这就是为什么有很多不良行为。

如果你已经上网成瘾,你应该做什么呢?这不是一个好主意,突然地戒掉。那么,你应该自己把它逐渐戒掉。首先,你必须明白一个要点,那就是生活在现实世界中比你在电脑屏幕上任何东西都丰富得多。所以你应该缩短花在网上的时间。当然,你需要的自我控制和毅力。 互联网是一把双刃剑。如果你充分利用它,你会受益匪浅。否则,就可能造成极大的危害。

从整体来看,我们应该继续使用互联网。不过,与此同时,我们应区别信息是否值得相信。只有这样才能让互联网发挥它最好的作用!

计算机英语科技小短文篇三：科技英语文章翻译

科技英语文章翻译

任何作品均有特定的文体，原文的文体不同，翻译方法也随之而异。试观察下列几个片断的原文及其译文。

"It appears that you've got the offer of a very good job."

"A wonderful job."

"Are you going to take it ?"

"I don't think so."

"Why not?'

"I don't want to."

“听说有个很好的工作要你去干。”

“挺好的工作。”

“打算干吗？”

“不。”

“为什么不干？”

“不想干。”

这是小说中的一段对说，属于口语文体。其特点是：用词自由，句法结构简单，短句与省略句多，自然朴素，生活气息浓厚。在译文中进一步体现汉语口语的特点，省去主语“你”、“我”；将英语的一个句子I don't think so。干脆译成一个字“不”，显得简洁有力。

She was of a helpless, fleshy build, with a frank, open countenance and an innocent, diffident manner. Her eyes were large and patient, and in them dwelt such a shadow of distress as only those who have looked

sympathetically into the countenances of the distraught and helpless poor know anything about.

那妇人生着一副绵软多肉的体格，一张坦率开诚的面容，一种天真羞怯的神气。一双大落落的柔顺眼睛，里边隐藏着无穷的心事，只有那些对于凄惶无告的穷苦人面目作过同情观察的人才看得出来。上面五十一个词的片断，就运用了十个形容词，占五分之一。and in then dwelt such a shadow of distress是非常优美生动的文学语言，译文保持了一风格。

Johns accomplished a spectacular debut for his NHL career tonight, the first score launching a four -point first period out burst,to lead the Johnson City High Hats to a 6:4 victory over the Montreal Teals and their eighth consecutive game without a loss.

在全国手球联赛中克拉克约翰斯今晚初试锋芒，引起轰动。上半场领先四分，首开记录。克拉克发挥中坚作用，约翰逊市高帽队终以6:4击败蒙特利尔市小鸭队，创造了连胜八场未负一场的战绩。

这是属于应用文的新闻文体，其特点是简明扼要，短小精悍，结构紧凑，笔锋犀利。上述这则电讯只有一个句子，却把一场球赛描绘得淋漓尽致，富于吸引力。

The range of a voltmeter may be extended by means of a series resistor called a multiplier as shown in Fig.2.The fullscale reading of the meter alone may be 15volts.With the multiplier 250volts may be required to move the pointer to full-scale, 135 volts across the multiplier and 15volts across the meter.

从上述的一段科技文章，不难看出其文体与修辞手段与前面列举的文艺小说，新闻报道等迥然不同。科技文体崇尚严谨周密，概念准确，逻辑性强，行文简练，重点突出，句式严整，少有变化，常用前置性陈述，即在句中将主要信息尽量前置，通过主语传递主要信息。

科技文章文体的特点是：清晰、准确、精练、严密。那末，科技文章的语言结构特色在翻译过程中如何处理，这是进行英汉科技翻译时需要探讨的问题。现分述如下：

一、大量使用名词化结构

《当代英语语法》（A Grammar of Contemporary）在论述科技英语时提出，大量使用名词化结构（Nominalization）是科技英语的特点之一。因为科技文体要求行文简洁、表达客观、内容确切、信息量大、强调存在的事实。而非某一行为。

Archimeds first discovered the principle of displacement of water by solid bodies.

阿基(转 载 于:wWW.ZHaoqT.nEt 蒲 公英文 摘:计算机英语科技小短文)米德最先发展固体排水的原理。句中of displacement of water by solid bodies 系名词化结构，一方面简化了同位语从句，另一方强调displacement 这一事实。

The rotation of the earth on its own axis causes the change from day to night.

地球绕轴自转，引起昼夜的变化。名词化结构the rotation of the earth on its own axis 使复合句简化成简单句，而且使表达的概念更加确切严密。

If you use firebricks round the walls of the boiler, the heat loss. Can be considerably reduced.

炉壁采用耐火砖可大大降低热耗。

科技英语所表述的是客观规律，因之要尽量避免使用第一、二人称；此外，要使主要的信息置于句首。

Television is the transmission and reception of images of moving objects by radio waves.

电视通过无线电波发射和接受活动物体的图象。

名词化结构the transmission and reception of images of moving objects by radio waves 强调客观事实，而"谓语动词则着重其发射和接受的能力。

二、广泛使用被动语句

根据英国利兹大学John Swales 的统计，科技英语中的谓语至少三分之一是被动态。这是因为科技文章侧重叙事推理，强调客观准确。第一、二人称使用过多，会造成主观臆断的印象。因此尽量使用第三人称叙述，采用被动语态，例如：

Attention must be paid to the working temperature of the machine.应当注意机器的工作温度。而很少说：You must pay attention to the working

temperature of the machine .你们必须注意机器的工作温度。此外，如前所述，科技文章将主要信息前置，放在主语部份。这也是广泛使用被动态的主要原因。试观察并比较下列两段短文的主语。

We can store electrical energy in two metal plates separated by an

insulating medium. We call such a device a capacitor, or a condenser, and its ability to store electrical energy capacitance .It is measured in farads.

电能可储存在由一绝缘介质隔开的两块金属极板内。这样的装置称之为电容器，其储存电能的能力称为电容。电容的测量单位是法拉。这一段短文中各句的主语分别为：

Electrical energy

Such a device

Its ability to store electrical energy

It (Capacitance )

它们都包含了较多的信息，并且处于句首的位置，非常醒目。四个主语完全不同，避免了单调重复，前后连贯，自然流畅。足见被动结构可收简洁客观之效。

三、非限定动词。

如前所述，科技文章要求行文简练，结构紧凑，为此，往往使用分词短语代替定语从句或状语从句；使用分词独立结构代替状语从句或并列分句；使用不定式短语代替各种从句；介词十动名词短语代替定语从句或状语从句。这样可缩短句子，又比较醒目。试比较下列各组句子。

A direct current is a current flowing always in the same direction.

直流电是一种总是沿同一方向流动的电流。

Radiating from the earth, heat causes air currents to rise.

热量由地球辐射出来时，使得气流上升。

A body can more uniformly and in a straight line,there being no cause to change that motion.

如果没有改变物体运动的原因，那么物体将作匀速直线运动。

Vibrating objects produce sound waves ,each vibration producing one sound wave.

振动着的物体产生声波，每一次振动产生一个声波。

In communications, the problem of electronics is how to convey

information from one place to another.

在通讯系统中，电子学要解决的问题是如何把信息从一个地方传递到另一个地方。

Materials to be used for structural purposes are chosen so as to behave elastically in the environmental conditions.

结构材料的选择应使其在外界条件中保持其弹性。

There are different ways of changing energy from one form into another.将能量从一种形式转变成另一种形式有各种不同的方法。

In making the radio waves correspond to each sound in turn ,messages are carried from a broadcasting station to a receiving set.

使无线电波依次对每一个声音作出相应变化时，信息就由广播电台传递到接收机。

四、后置定语

大量使用后置定语也是科技文章的特点之一。常见的结构不以下五种：

1、介词短语

The forces due to friction are called frictional forces.

由于摩擦而产生的力称之为摩擦力。

A call for paper is now being issued .

征集论文的通知现正陆续发出。

2、形容词及形容词短语。

In this factory the only fuel available is coal.

该厂唯一可用的燃料是煤。

In radiation ,thermal energy is transformed into radiant energy ,similar in nature to light.

热能在辐射时，转换成性质与光相似的辐射能。

3、副词

The air outside pressed the side in .

外面的空气将桶壁压得凹进去了。

The force upward equals the force downward so that the balloon stays at the level.

向上的力与向下的力相等，所以气球就保持在这一高度。

4、单个分词，但仍保持校强的动词意义。

The results obtained must be cheeked .

获得的结果必须加以校核

The heat produced is equal to the electrical energy wasted.
