        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.

        轉(zhuǎn)基因食品:它們是安全的?-轉(zhuǎn)基因作物環(huán)境的夢想或災(zāi)難正在形成?科學(xué)家們正在尋找答案,世界似乎越來越分為那些喜歡轉(zhuǎn)基因(GM)食品和那些害怕他們。支持者宣稱,種植基因改造作物可以有益于環(huán)境,食用從這些植物食品是完全安全的。并且,他們說,遺傳工程-可誘導(dǎo)植物在貧瘠的土壤中生長出更有營養(yǎng)的食物-將很快成為幫助養(yǎng)活世界不斷增長的人口的一個必不可少的工具。懷疑論者聲稱,轉(zhuǎn)基因作物可能構(gòu)成了獨特的風(fēng)險,對環(huán)境和健康風(fēng)險-太麻煩接受平穩(wěn)。以這種觀點,許多歐洲國家是限制種植轉(zhuǎn)基因農(nóng)產(chǎn)品進口。爭論大多取決于安全的看法。但它究竟是什么,最近的科學(xué)研究說危險嗎?的答案,往往迷失在對爭議的報告,提供了在接下來的幾頁。

        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.

        ??"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!??

        “網(wǎng)絡(luò)”現(xiàn)在是如此受歡迎,它已經(jīng)滲透到我們的日常生活中,改變我們?nèi)绾伪3致?lián)系,分享信息,完成家務(wù),甚至賺取收入。一個全新的產(chǎn)業(yè)已經(jīng)出現(xiàn)了新的方法致力于提高生產(chǎn)力 ,使我們能夠適合進入更加忙碌的生活之中。

        你會用計算機嗎?你能上網(wǎng)嗎?我相信你的答案是“是的!”,F(xiàn)在,我們中的大多數(shù)人都能使用電腦上網(wǎng)。實際上,它對我們來說很重要,我們都知道我們上網(wǎng)沖浪能做許多的事情。例如,一些學(xué)生在他們的學(xué)習(xí)中也經(jīng)常上網(wǎng)去找好東西,通過上網(wǎng),他們可以學(xué)到很多東西,并取得很大的進步。在我們空閑的時候,我們經(jīng)常與我們的朋友或者家人聊天。在過去,如果我們離朋友或家人非常遠(yuǎn)時,我們只能寫信給對方,但是現(xiàn)在互聯(lián)網(wǎng)能解決這個問題,我們甚至可以說話甚至能看到對方。同時,我們可以在周末玩游戲,他們能幫助我們放松。當(dāng)然,我們也可以做許多其他的事。總之,因特網(wǎng),在我們的生活中是非常重要的。

        在電腦前和人聊天。顯然,他們在虛擬網(wǎng)絡(luò)世界中迷去了自己,成為互聯(lián)網(wǎng)的奴隸。因此,不抓住這個機遇,而不是去完成任何事情自然成為許多人信條。怎么會這樣呢?網(wǎng)絡(luò),就像毒品、香煙、酒等.它的奧秘取在于它是虛擬現(xiàn)實。舉例來說,當(dāng)你在網(wǎng)上和別人聊天時,身份和外觀意味著很小的空間,但你的想法是真的。這種看不到對方的溝通是沒問題的。在這時,而不是顯示你的弱點,你通常會炫耀你的長處。各位網(wǎng)友想做同樣的事情,然后欣賞對方,最后他們甚至形成的愛的關(guān)系。然而,很難知道真正的另外的一個人是誰。但通常他或她無法辨認(rèn)出這一點,這對夫婦還不能見面。一旦他們見面,這將不可避免地失望。網(wǎng)上的男朋友(女朋友)你想象的有很大不同。即使那個人是邪惡。使情況更為糟糕的是, 結(jié)果很有可能是太可怕的沉思。并且經(jīng)常它沒有真正的基礎(chǔ)。此外,我們不能忽視是上網(wǎng)時間長,每天都花很多錢,這就是為什么有很多不良行為。

        如果你已經(jīng)上網(wǎng)成癮,你應(yīng)該做什么呢?這不是一個好主意,突然地戒掉。那么,你應(yīng)該自己把它逐漸戒掉。首先,你必須明白一個要點,那就是生活在現(xiàn)實世界中比你在電腦屏幕上任何東西都豐富得多。所以你應(yīng)該縮短花在網(wǎng)上的時間。當(dāng)然,你需要的自我控制和毅力。 互聯(lián)網(wǎng)是一把雙刃劍。如果你充分利用它,你會受益匪淺。否則,就可能造成極大的危害。

        從整體來看,我們應(yīng)該繼續(xù)使用互聯(lián)網(wǎng)。不過,與此同時,我們應(yīng)區(qū)別信息是否值得相信。只有這樣才能讓互聯(lián)網(wǎng)發(fā)揮它最好的作用!

        科技英語文章翻譯

        任何作品均有特定的文體,原文的文體不同,翻譯方法也隨之而異。試觀察下列幾個片斷的原文及其譯文。

        "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."

        “聽說有個很好的工作要你去干!

        “挺好的工作!

        “打算干嗎?”

        “不。”

        “為什么不干?”

        “不想干!

        這是小說中的一段對說,屬于口語文體。其特點是:用詞自由,句法結(jié)構(gòu)簡單,短句與省略句多,自然樸素,生活氣息濃厚。在譯文中進一步體現(xiàn)漢語口語的特點,省去主語“你”、“我”;將英語的一個句子I don't think so。干脆譯成一個字“不”,顯得簡潔有力。

        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.

        那婦人生著一副綿軟多肉的體格,一張?zhí)孤书_誠的面容,一種天真羞怯的神氣。一雙大落落的柔順眼睛,里邊隱藏著無窮的心事,只有那些對于凄惶無告的窮苦人面目作過同情觀察的人才看得出來。上面五十一個詞的片斷,就運用了十個形容詞,占五分之一。and in then dwelt such a shadow of distress是非常優(yōu)美生動的文學(xué)語言,譯文保持了一風(fēng)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.

        在全國手球聯(lián)賽中克拉克約翰斯今晚初試鋒芒,引起轟動。上半場領(lǐng)先四分,首開記錄?死税l(fā)揮中堅作用,約翰遜市高帽隊終以6:4擊敗蒙特利爾市小鴨隊,創(chuàng)造了連勝八場未負(fù)一場的戰(zhàn)績。

        這是屬于應(yīng)用文的新聞文體,其特點是簡明扼要,短小精悍,結(jié)構(gòu)緊湊,筆鋒犀利。上述這則電訊只有一個句子,卻把一場球賽描繪得淋漓盡致,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.

        從上述的一段科技文章,不難看出其文體與修辭手段與前面列舉的文藝小說,新聞報道等迥然不同。科技文體崇尚嚴(yán)謹(jǐn)周密,概念準(zhǔn)確,邏輯性強,行文簡練,重點突出,句式嚴(yán)整,少有變化,常用前置性陳述,即在句中將主要信息盡量前置,通過主語傳遞主要信息。

        科技文章文體的特點是:清晰、準(zhǔn)確、精練、嚴(yán)密。那末,科技文章的語言結(jié)構(gòu)特色在翻譯過程中如何處理,這是進行英漢科技翻譯時需要探討的問題,F(xiàn)分述如下:

        一、大量使用名詞化結(jié)構(gòu)

        《當(dāng)代英語語法》(A Grammar of Contemporary)在論述科技英語時提出,大量使用名詞化結(jié)構(gòu)(Nominalization)是科技英語的特點之一。因為科技文體要求行文簡潔、表達客觀、內(nèi)容確切、信息量大、強調(diào)存在的事實。而非某一行為。

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

        阿基(轉(zhuǎn) 載 于:smilezhuce.com 蒲 公英文 摘:計算機英語科技小短文)米德最先發(fā)展固體排水的原理。句中of displacement of water by solid bodies 系名詞化結(jié)構(gòu),一方面簡化了同位語從句,另一方強調(diào)displacement 這一事實。

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

        地球繞軸自轉(zhuǎn),引起晝夜的變化。名詞化結(jié)構(gòu)the rotation of the earth on its own axis 使復(fù)合句簡化成簡單句,而且使表達的概念更加確切嚴(yán)密。

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

        爐壁采用耐火磚可大大降低熱耗。

        科技英語所表述的是客觀規(guī)律,因之要盡量避免使用第一、二人稱;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.

        電視通過無線電波發(fā)射和接受活動物體的圖象。

        名詞化結(jié)構(gòu)the transmission and reception of images of moving objects by radio waves 強調(diào)客觀事實,而"謂語動詞則著重其發(fā)射和接受的能力。

        二、廣泛使用被動語句

        根據(jù)英國利茲大學(xué)John Swales 的統(tǒng)計,科技英語中的謂語至少三分之一是被動態(tài)。這是因為科技文章側(cè)重敘事推理,強調(diào)客觀準(zhǔn)確。第一、二人稱使用過多,會造成主觀臆斷的印象。因此盡量使用第三人稱敘述,采用被動語態(tài),例如:

        Attention must be paid to the working temperature of the machine.應(yīng)當(dāng)注意機器的工作溫度。而很少說:You must pay attention to the working

        temperature of the machine .你們必須注意機器的工作溫度。此外,如前所述,科技文章將主要信息前置,放在主語部份。這也是廣泛使用被動態(tài)的主要原因。試觀察并比較下列兩段短文的主語。

        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.

        電能可儲存在由一絕緣介質(zhì)隔開的兩塊金屬極板內(nèi)。這樣的裝置稱之為電容器,其儲存電能的能力稱為電容。電容的測量單位是法拉。這一段短文中各句的主語分別為:

        Electrical energy

        Such a device

        Its ability to store electrical energy

        It (Capacitance )

        它們都包含了較多的信息,并且處于句首的位置,非常醒目。四個主語完全不同,避免了單調(diào)重復(fù),前后連貫,自然流暢。足見被動結(jié)構(gòu)可收簡潔客觀之效。

        三、非限定動詞。

        如前所述,科技文章要求行文簡練,結(jié)構(gòu)緊湊,為此,往往使用分詞短語代替定語從句或狀語從句;使用分詞獨立結(jié)構(gòu)代替狀語從句或并列分句;使用不定式短語代替各種從句;介詞十動名詞短語代替定語從句或狀語從句。這樣可縮短句子,又比較醒目。試比較下列各組句子。

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

        直流電是一種總是沿同一方向流動的電流。

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

        熱量由地球輻射出來時,使得氣流上升。

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

        如果沒有改變物體運動的原因,那么物體將作勻速直線運動。

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

        振動著的物體產(chǎn)生聲波,每一次振動產(chǎn)生一個聲波。

        In communications, the problem of electronics is how to convey

        information from one place to another.

        在通訊系統(tǒng)中,電子學(xué)要解決的問題是如何把信息從一個地方傳遞到另一個地方。

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

        結(jié)構(gòu)材料的選擇應(yīng)使其在外界條件中保持其彈性。

        There are different ways of changing energy from one form into another.將能量從一種形式轉(zhuǎn)變成另一種形式有各種不同的方法。

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

        使無線電波依次對每一個聲音作出相應(yīng)變化時,信息就由廣播電臺傳遞到接收機。

        四、后置定語

        大量使用后置定語也是科技文章的特點之一。常見的結(jié)構(gòu)不以下五種:

        1、介詞短語

        The forces due to friction are called frictional forces.

        由于摩擦而產(chǎn)生的力稱之為摩擦力。

        A call for paper is now being issued .

        征集論文的通知現(xiàn)正陸續(xù)發(fā)出。

        2、形容詞及形容詞短語。

        In this factory the only fuel available is coal.

        該廠唯一可用的燃料是煤。

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

        熱能在輻射時,轉(zhuǎn)換成性質(zhì)與光相似的輻射能。

        3、副詞

        The air outside pressed the side in .

        外面的空氣將桶壁壓得凹進去了。

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

        向上的力與向下的力相等,所以氣球就保持在這一高度。

        4、單個分詞,但仍保持校強的動詞意義。

        The results obtained must be cheeked .

        獲得的結(jié)果必須加以校核

        The heat produced is equal to the electrical energy wasted.
