『壹』 英語作文是關於轉基因食品的進口的贊同與反對最後是自己的觀點
Today there are 6 billion people on the earth. By the year 2050 there may be 12.5 billion. This is a lot of people to feed. We need more food.
One way to proce more food is by growing stronger plants. For thousands of years, farmers have made plants better. Every season, they pick the best plants for the next season. It works very slowly. Since 1983, scientists have been able to change plants more quickly by changing their genetic material(遺傳物質). Foods from plants grown in this way are called genetically modified foods(轉基因食品), or GM foods.
By changing the genetic material of a plant, it is possible to make new plants. They make plants which are strong against plant diseases. They can also help with our diseases: a kind of rice is being prepared(准備), for example, which stops people from becoming blind.
Rich countries proce GM foods because they are easy to grow and bring in more money. Poor countries are interested in them because they help proce more food.
GM plants are not natural. No one knows how good or bad they are. Making GM foods is only one way of feeding people in 2050. There are strong feelings against them, because they are unnatural. They may feed people, then hurt them or their children later. But, both rich and poor countries are very interested in their use, and they are not going to go away. In 2050 We may think differently about them.

Genetically modified food
轉基因食品

The success of genetically modified crops provides opportunities to win over their critics
轉基因作物的成功為說服其批評者提供了機遇。
Feb 25th 2010 | From The Economist print edition
IN THE 14 years since the first genetically modified crops were planted commercially, their descendants, relatives and remixes have gone forth and multiplied like profitable, high-tech pondweed. A new report (see article) shows that 25 countries now grow GM crops, with the total area under cultivation now larger than Peru. Three-quarters of the farmland used to grow soya is now sown with a genetically modified variant, and the figures for cotton are not that far behind, thanks to its success in India. China recently gave the safety go-ahead to its first GM rice variety and a new GM maize that should make better pig feed. More and more plants are having their genomes sequenced: a full sequence for maize was published late last year, the soya genome in January. Techniques for altering genomes are moving ahead almost as fast as the genomes themselves are stacking up, and new crops with more than one added trait are coming to market.
Such stories of success will strike fear into some hearts, and not only in GM-averse Europe; a GM backlash is under way in India, focused on insect-resistant aubergines. Some of these fears are understandable, but lacking supporting evidence they have never been compelling. On safety, the fear which cuts closest to home, the record continues to look good. Governments need to keep testing and monitoring, but that may be becoming easier. More precise modifications, and better technologies for monitoring stray DNA both within plants and in the environment around them, mean that it is getting easier to be sure that nothing untoward is going on.
自轉基因首次走向市場的14年中,它們的後代、類似品種以及雜交品種不斷出現並增多如可獲利的高科技水池草。一份新出的報告顯示,目前已有25個國家種植轉基因作物,正在培植的作物的面積比秘魯的面積還要大。曾經種植大豆的四分之三的農田現在都用於種植轉基因品種,用於種植棉花的農田面積也並非遠遠落後,因為它在印度很受歡迎。最近中國確保種植其首個轉基因品種和新開發的轉基因玉米,這必將給豬帶來更好的飼料。越來越多作物的基因序列得到確定,玉米的整個序列在去年年末公布了,大豆的基因在1月份也公布了。技術改變基因的速度與基因自身重組的速度相當,具有多種其它特性的新品種正向市場進發。
這種成功的報道將使一些人擔心,這種擔心不僅僅出現在反對轉基因作物的歐洲。轉基因作物在印度也遭到強烈的反對,主要集中反對抗蟲茄子。其中的一些擔心可以理解,但是缺乏可靠證據,它們從來就沒有說服力。在安全方面,這種擔心與家庭的關系最密切,所作的記錄還是表明是好的。政府需要不斷試驗和監控,不過這或許正變得更加簡單。更加精確的改良和更加先進的監控作物及其環境中的游離的DNA的技術意味著更加容易保證不出現異常現象。
Then there is the worry that GM crops are a way for big companies to take over the livelihoods of small farmers and, in the end, a chunk of nature itself. Seen in this light the fact that 90% of the farmers growing GM crops are comparatively poor and in developing countries is sinister, not salutary; given Monsanto』s dominance in America』s soyabean market, it seems to suggest incipient world domination. It is certainly true that big firms make a lot of money selling GM seeds: the GM seed market was worth $10.5 billion in 2009, and the crops that grew from that seed were worth over $130 billion. But multinationals are not the only game in town. The governments of China (which has increased agricultural research across the board), India and Brazil are also developing new GM crops. In 2009 a GM version of an Indian cotton variety, developed in the public sector, came to market, and a variety engineered by a private Indian firm has been approved for commercialisation. Charities, such as the Bill and Melinda Gates Foundation, are also funding efforts in various countries to make crops more hardy or nutritious. GM seeds that come from government research bodies, or from local firms, may not arouse quite so much opposition as those from large foreign companies, especially when they provide characteristics that make crops better, not just easier to farm.
還有一種擔心,就是轉基因作物是大公司剝奪小農生計的一種方法,最終也會破壞大自然本身。從這種角度看,轉基因作物的90%的農民都相對較貧窮,都來自發展中國家是有害的,而不是有益的。Monsanto支配著美國的大豆市場,這似乎暗示著初步支配了世界。大公司通過出售轉基因種子可以賺取很多錢,這顯然是事實:2009年,轉基因種子市場的銷售額為105億美元,而這些種子種出的作物價值為1300億美元。中國(在全國加強農業研究)、印度和巴西政府也在開發新的轉基因作物。2009年,公共部門開發的印度棉花品種的轉基因品種走向了市場,有印度一家私營公司研製的品種已經批准用於商業。如比爾梅琳達蓋茨基金會等慈善機構也在為多國的努力提高資金,讓作物更加的強壯或更加具有營養價值。尤其當他們的品種具有的特性可以使作物更好,而不僅僅是更容易種植時,來自政府研究機構或當地公司的轉基因種子或許不會像來自大型外國公司一樣遭到很多反對。
Moreover, where the seeds come from is a separate question from who should pay for them, as Mr Gates points out. As with drugs and vaccines, it is possible to get procts that were developed with profit in mind to the people who need them using donor money and clever pricing and licensing deals. In the longer term, if the seeds deliver what the farmers require, the need for such special measures should diminish. After all, the whole idea is not that poor farmers should go on being poor. It is that poor farmers should get a bit richer, be able to invest a bit more, and thus increase the food available to a growing and predominantly urban population.
此外,正如蓋茨指出的那樣,種子的來源和誰購買它們是兩個問題。正如葯物和疫苗一樣,通過使用捐款者的錢以合理的價格和經許可的協議可以獲得產品,這些產品本是以獲利為目的而為那些需要它們的人研製的。從長遠來說,如果這些種子正是農民們需要的,這種特殊的措施就都沒必要了。畢竟,整個理念並不是貧窮的農民必須要繼續貧窮,而是貧窮的農民必須要富一點起來,能夠多投資點,這樣糧食才能滿足日益增長和以城市人口為主的人口的需要。
More than strange fruits
不僅僅是奇怪的水果
There is another worry about GM technology, though, that should be taken seriously. It is that its success and appeal to technophiles may, in the minds of those who pay for agricultural research, crowd out other approaches to improving farming. Because it depends on intellectual property that can be protected, GM is ripe for private investment. There is a lot of other agricultural research that is less amenable to corporate ownership but still needs doing. From soil management to weather forecasts to the preservation, study and use of agricultural biodiversity, there are many ways to improve the agricultural systems on which the world』s food supply depends, and make them more resilient as well as more profitable. A farm is not a just a clever crop: it is an ecosystem managed with intelligence. GM crops have a great role to play in that development, but they are only a part of the whole.
必須嚴肅對待另一種對轉基因技術的擔憂。轉基因作物的成功以及新科技迷對此技術很感興趣,那些為農業研究提供資金的人可能不會再想其它方法改善種植情況。因為知識產權會受到保護,私人投資轉基因作物的機會已經成熟。其它很多農業研究都不那麼適合公司掌控,但仍然需要進行。從土壤管理、天氣預測到農業生物多樣性的保護、研究和利用很多領域,改善農業系統還有很多途徑,世界的糧食供應都要依靠農業系統,因此要使它們更加富有活力,產出更多利潤。一塊農田不僅是一種高產的莊稼:它是需要人為管理的生態系統。轉基因作物在這個方向上有很好的發展前景,但它們只是其中的一部分。
『叄』 關於對轉基因食物的優點和缺點及自己看法的英語作文
這就是關於轉基因食品優缺點的作文:Genetically modified food is science brings us the proct, now of cultivated land area of less, genetically modified food will play more and more important role, if the use of transgenic technology can solve the world food shortage problem, it is not quite good? Genetically modified food in the world now is a kind of new things, new things, people need time to promote its accept also need some time, we cannot put new things in the cradle, a stick to it from the beginning, that cannot be eaten of genetically modified food. You think we don't of hybrid rice is a genetically modified food? But we can open it from? And if they can pass the soybeans genetically modified technique using atmospheric nitrogen inside his proces fertilizers to other crops gene transfer in the mankind, it is. Everything is both sides, especially technology, science and technology is a double-edged sword? Genetically modified food has its disadvantages, like some worry, because it will not change, will destroy genetic evolution, etc. Genetically modified food and nutrition inside it isn't like that, the propaganda of people worry is understandable, after accepting a new things take time. But we also should see the benefits of them, I think as time slowly past, genetically modified foods will be accepted by people. 希望會對你有幫助吧,謝謝!
You Are What You Eat
食物影響你的身(你是你所吃進去的)
Genetic(基因的)engineering is the scientific change of the genetic material in a
living organism.It allows scientists to identify specific genes, to remove them from
an organism's chromosomes (染色體), improve them, analyze them, and possibly clone them, and to then reinsert the changed gene into the original organism, or a completely different organism.Unlike traditional breeding (繁殖), where a desired quality would be bred within the same species, genetic engineering can insert desired ones into organisms of different species.Wow…Did you catch that?
基因工程一個研究生物體內遺傳物質的變化的學科。它使科學家們能夠定義具體的基因,並通過移動生物體內染色體上的基因來提升和分析這些生物,甚至可能克隆它們。之後,科學家們會重新把提取出的已經改變了的基因注射回原來的生物體內,或者注射到完全不同的一個個體中。不像傳統的繁殖需要通過繁衍同一個高質量的物種,基因工程可以導入基因到不同的物種里。哇。。。你跟上了嗎?
Genetic engineering creates many positive contributions to agriculture.For example, by genetically engineered(GE)foods, anti-cancer agents, minerals and vitamins can be increased.Improved taste, shelf life, and better transport are all possible.Also, GE plants can increase pest and bacterial resistance, therefore, making the food safe for consumers.
基因工程對農業做出了很多好的貢獻。比如說,通過傳基因技術的食物在抗癌物質,礦物質和維他命方面都有提高。口感,在超市的貨價擺放時間以及運輸上都有更高的提升空間。另外,轉基因植物的抗害蟲和細菌的能力都有曾強,所以可以提供出更加完全的食物。
The public is also concerned about the unknown health risks.With limited understanding of genes, scientists cannot predict possible effects.Because most genes introced into GE plants come from sources not introced into the human
body, it is impossible to know if they will cause reactions.Moreover, e to the lack of labeling if allergies develop, it will be extremely difficult to find the origin of them.
同時,公眾也會擔心這些轉基因食物所帶來的未知的風險。由於對於基因理解的局限性,科學家們也不能預測出可能的影響。因為大多數用於轉基因植物的基因的來源並沒有人類採用過,所以也不能知道人在攝取轉基因食物後體內會有什麼反應。另外,由於缺乏在商品上對過敏的標識,很能判斷出在人的體內的不良反應的准確來源(也有可能是由過敏導致的)。
There is also a major moral question in many minds.For many, the conflict is not if it is safe or not, but it disturbs them because it is unnatural and unnecessary.We are currently procing one and a half times the amount of food needed to feed the
world, yet one in seven people are starving.GE food is unnecessary, and fails to address the root of hunger.Many believe that the only people who will benefit are the corporations that proce it.
很多人也會把轉基因食物的問題引伸到道德上的問題。對於很多人來說,他們擔心的不是安全性而是轉基因食物的非自然和非必要性。我們人類目前產出的食物是世界所需總量的1.5倍,但是還是有很多地區的人面臨著飢荒。轉基因食物不是必需的,而已無法根治飢荒。很多人相信只有生產這些作物的集團公司可以從中獲益。
Scientists cannot foresee the possible effects of GE foods, yet we eat them every day without even knowing it.We already have enough food, so why create more that
could be potentially harmful to us, to the Earth and to all wildlife? I think that the benefits are amazing, but until we know for sure how these foods will affect us, they are not worth the risk.
科學家不能預測轉基因食物對人類社會所帶來的影響,但是我們卻不知道我們現在每天就在吃這些轉基因食物。 我們已經有足夠的食物,所以如果再繼續生產食物會不會對我們,對地球,對野生動物產生潛在的危害?我(筆者)認為轉基因食物所帶來的利益是不可想像的,但是我們不值得嘗試這些食物的潛在風險知道我們可以確定它們會給我們帶來什麼影響。
求採納!

生物與環境平衡的危機
The history of life on earth has been a history of interaction between living things and their surroundings. To a large extent, the physical form and the habits of the earth’s vegetation and its animal life have been molded by the environment. Considering the whole span of earthly time, the opposite effect, in which life actually modifies its surroundings, has been relatively slight. Only in the present century has one species man acquired significant power to alter the nature of his world.
During the past quarter century this power has not only become increasingly great but it has changed in character. The most alarming of all man’s assaults upon the environment is the contamination of air, earth, rivers, and sea with dangerous and even lethal materials. This pollution is for the most part irrecoverable. In this now universal contamination of the environment, chemicals are the sinister partners of radiation in changing the very nature of the world the very nature of its life. Chemicals sprayed on croplands or forests or gardens lie long in soil, entering into living organisms, passing from one to another in a chain of poisoning and death. Or they pass mysteriously by underground streams until they emerge and combine into new forms that kill vegetation, sicken cattle, and work unknown harm on those who drink from once pure wells. "Man can hardly even recognize the devils of his own creation," as a scientist has said.
It took hundreds of millions of years to proce the life that now inhabits the earth. Given time not in years but in millennia life adjusts, and a balance has been reached. But in the modern world there is no time.
The rapidity of change follows the impetuous pace of man rather than the deliberate pace of nature. Radiation is now the unnatural creation of man’s tampering with the atom. The chemicals are the synthetic5 creations of man’s inventive mind, having no counterparts in nature.
To adjust to these chemicals would require not merely the years of a man’s life but the life of generations. And even this, were it by some miracle possible, would be futile, for the new chemicals come from our laboratories in an endless stream; almost five hundred annually find their way into actual use in the United States alone. Among them are many that are used in man’s war against nature. Since the mid 1940’s over 200 basic chemicals have been created for use in killing insects, weeds, and other organisms described as "pests."
It is not my contention that chemical insecticides must never be used. I do contend that we have put poisonous and biologically potent chemicals indiscriminately into the hands of persons largely or wholly ignorant of their potentials for harm. We have subjected enormous numbers of people to contact with these poisons, without their consent and often without their knowledge. I contend, furthermore, that we have allowed these chemicals to be used with little or no advance investigation of their effect on soil, water, wildlife, and man himself. Future generations are unlikely to forgive our lack of concern for the integrity of the natural world that supports all life.
地球上生命的歷史一直就是一部生物與其環境相互作用的歷史。在很大程度上,地球上動植物的形態以及習性都是由外部環境所塑造的。考慮到地球上生命存在的整個時間,相反作用,即生命對其周圍環境的實際改變作用,卻相對很小。只有在當前這個世紀(指20世紀)才有一個物種--人類,獲得了強大的力量,改變了其所生存的世界的自然狀態。
在過去的1/4世紀中,這種力量不僅日趨強大,而且其性質也發生了變化。在人類破壞環境的種種行為中,最令人擔憂的是人類向大氣、土壤、河流以及海洋中排放危險甚至致命物質,而當今這種污染在很大程度上是無法挽救的。在當今這種對環境的普遍污染中,化學製品與輻射狼狽為奸,改變著地球的自然狀態,也就是改變著地球上生命的自然狀態。噴灑到農田、森林或者花園里的化學物質長期滯留於土壤中,滲入有機體內,並彼此相傳,形成了一個中毒與死亡的鏈條。化學物質還神秘地通過地下水傳遞,最終以新的形式出現並結合,使植物毒死,牲畜害病,並使飲用一度純凈的井水的人遭受了不明之害。正如一位科學家所言:“人類甚至對自己創造的惡魔都不認識。”
地球歷經了許多億年才創造了棲息其上的生命。經過了一定時間--不是以若干年計而是以若干千年計的時間--生命開始適應環境,並形成了一種與環境的平衡。但是在現代世界中,時間這一因素已經沒有了。
環境改變的速度不再順從大自然從容不迫的節奏,而是順從人類急切匆匆的步伐。輻射是當今人類通過支配原子而得到的一種非自然的創造物。化學製品則是人類有發明創造力的頭腦創造出來的合成物,在自然界本無相應的東西。
為了適應這些化學製品,人類需要付出的時間不會只是一個人一生的時間,而是幾代人的時間。而即使這樣,就算出現奇跡成為可能,這種適應也是徒勞的,因為新的化學製品從我們的實驗室中源源不斷地湧出。僅在美國,每年就有大約500種化學製品投入使用,其中許多是用於人類對自然的戰爭中。從20世紀40年代中期起,人類已經創造了200多種基本化學製品用來消滅昆蟲、野草以及其他所謂的“有害生物”。
我不是說人類決不能使用化學殺蟲劑。我要說的是,我們不分青紅皂白地將這些有毒的、具有強大生物功能的化學製品,交給了那些對這些製品的潛在危害基本上或者完全無知的人去使用。我們使眾多的人接觸這些有毒物質,卻沒有徵得他們的同意,並常常將他們蒙在鼓中。我還要說的一點是,我們允許使用這些化學製品,卻事先很少或者根本沒有調查它們對土壤、水、野生生物以及人類自身造成的影響。我們缺乏對萬物賴以生存的自然界生態統一的關心,對此,我們的後代是不可能原諒的。

基因技術能否使人更聰明?Get Smart
Many people dream of having a smarter brain. Princeton neurobiologist Joseph Z. Tsien found the key. In September he announced that he’d built a better mouse by altering a gene that affects learning and memory. A similar process of gene manipulation might conceivably be used one day to boost intelligence in humans.
The secret lies in a feature of brain cells called the nmda receptor, which Tsien likens[1] to a cylindrical tube or window that mediates[2] the flow of information. When the window is open, chemicals called neurotransmitters flow through easily and memory is registered and stored. But as organisms mature, the window begins to close. (This may explain why children lose their facility for learning new languages when they reach sexual maturity and why some people suffer memory loss as they age.)
Tsien noticed that the receptor worked more efficiently when teamed[3] with the gene NR2B, so he introced extra NR2B genes into a batch of fertilized mouse eggs. In a normal mouse, the memory window is open for just 150-thousandths of a second. In Tsien’s specially engineered mice, the window opens for 250-thousandths of a second, long enough to make a remarkable difference in memory retention. When he pitted[4] his mice against common mice, they won paws down. Ordinary mice could recognize a Lego block for 12 hours, but smart mice could remember the block for up to three days. "That’s a profound enhancement," Tsien says.
Can it be done with humans? Maybe, but genetic engineering will have to make some extraordinary advances first. And some thorny ethical issues will have to be resolved. Meanwhile, Tsien promises to keep his furry little geniuses locked up in a lab, far from your larder. "Otherwise," he says, "you might need a smart cat or a smart mousetrap to catch them."
許多人都希望自己能變成更聰明。普林斯頓神經生物學家Joseph Z. Tsien就找到了這把開啟智慧之門的鑰匙:他於九月宣布,通過改變影響學習和記憶能力的基因培養出了一隻聰明的老鼠。類似的基因處理技術有望在未來日子裡運用到人腦,以推動人類智慧的飛躍。
該技術的奧秘就在於名為nmda感受器的腦細胞的功能。Tsien將其比作一個傳遞信息流的圓柱通道或窗口。當窗口開放時,某種稱為神經傳遞素的化學物質就能輕易流過,記憶因此登記並存儲了下來。然而,當器官成熟時,這扇窗口就開始關閉。(這也能解釋為何 兒童 長大後(性器官成熟之時)會失去掌握新語言的能力,以及為何某些人年老時會患失憶)。
Tsien注意到,當感受器與名為NR2B的基因協作時效率會更高。因此,他將NR2B基因植入一批老鼠的受精卵中。一隻普通老鼠的記憶之窗僅開放千分之150秒。而經Tsien植入基因的老鼠,記憶之窗能開放千分之250秒,這已經能夠使其 記憶力 發生驚人的改變。當他讓自己的老鼠與普通老鼠互斗時,它們竟能輕而易舉地取勝。普通老鼠能夠保留關於Lego block的記憶12小時,而聰明的老鼠居然能將記憶保持三天。“這可是一個意義深遠的進步。”Tsien這樣說。
那麼,人類也能接受這種基因移植嗎? 或許可以,但前提是基因工程得首先做出非凡的成就,還必須解決一系列棘手的倫理問題。Tsien保證他一定會將那些披著毛皮的小天才鎖入實驗室,遠離人們的食品櫃。“否則,”他說,“為了捉住他們,人們就不得不去尋找更聰明的貓或者功能更強的捕鼠器了。”

食用轉基因食品安全嗎?Food Safe To Eat?
Traditional plant breeding involve s crossing varieties of the same species in ways they could cross naturally.For example,disease-resistant varieties of wheat have been crossed with high-yield wheat to combine these properties.This type of natural gene exchange is safe and fairly predictable.
Genetic engineering(GE)involves exchanging genes between unrelated species that cannot naturally exchange genes with each other.GE can involve the exchange of genes between vastly different species――e.g.putting scorpion toxin genes into maize or fish antifreeze genes into tomatoes.It is possible that a scorpion toxin gene,even when it is in maize DNA,will still get the organism to proce scorpion toxin――but what other effects may it have in this alien environment?We are already seeing this problem――adding human growth hormone genes to pigs certainly makes them grow――but it also gives them arthritis and makes them cross-eyed,which was entirely unpredictable.
It will be obvious,for example,that the gene for human intelligence will not have the same effect if inserted into cabbage DNA as it had in human DNA――but what side-effect would it have?In other words,is GM food safe to eat?The answer is that nobody knows because long-term tests have not been carried out.
Companies wanting a GM proct approved in the UK or USA are required to provide regulatory bodies with results of their own safety tests.Monsanto’s soya beans were apparently fed to fish for10weeks before being approved.There was no requirement for independent testing,for long-term testing,for testing on humans or testing for specific dangers to children or allergic people.
The current position of the UK Government is that“ There is no evidence of long-term dangers from GM foods.”In the US,the American Food and Drug Administration is currently being prosecuted for covering up research that suggested possible risks from GM foods.
傳統的植物培育 方法 ,是依照植物自然雜交的方式,進行相同物種的人工雜交。比如,抗病小麥同高產小麥雜交,形成了一種具有雙重特性的新的小麥品種。這種自然的基因交換既安全,又具有相當的可預見性。
基因工程是在彼此毫無關系的物種之間,相互交換在自然條件下無法交換的基因。它可在有巨大差異的物種之間進行基因交換。比如,將蠍子毒素基因注入玉米,或者將魚防凍基因注入西紅柿。即使在玉米DNA中,蠍子毒素基因依然可能獲得有機組織產生蠍子毒素。但是在這種異質的環境中,這種基因產品會有什麼其他作用嗎?我們實際上已經發現這個問題:將人類生長荷爾蒙基因植入豬的體內,一定會使豬的生長加速,但是同時也使豬患上了關節炎和內斜視,而這一切是完全無法預測的。
打個比方,人類的智力基因顯而易見在人體DNA內和注入捲心菜DNA後的作用是不同的。但將它植入捲心菜中會產生什麼樣的副作用呢?換句話說,食用轉基因食品安全嗎?沒有人知道答案,因為人們尚未進行長期的測試。
在英國或者美國,一個公司如果希望其轉基因產品獲得批准,它必須向管理機構提供本公司轉基因產品安全測試的結果。Monsanto的大豆在獲得批准之前,曾用了10周時間進行喂魚試驗。目前,尚無要求對轉基因產品進行獨立測試、長期測試、人體測試,或者就其對兒童及過敏者所造成的特定危險進行測試。
英國政府目前的態度是:“尚無證據表明食用轉基因食品存在長期性的危險。”在美國,人們正在起訴美國食品葯品管理局掩蓋轉基因食品安全性的研究結果,這些研究結果表明,食用轉基因食品可能導致危險。
