第一篇:《关于转基因食品的英语作文》
The world's first commercial production of Genetically modified food (GMF) is delay the maturity of Genetically modified tomato,which was put into the United States market in 1994. There is no denying the fact that the number of GMF is steadily increasing in the 21st century. So,what is the so-called GMF?
GMF is a kind of food that is embedded foreign gene in the genome of the species by genetic engineering technology to meet human needs,including transgenic plant food,transgenic animal food and transgenic microorganism food. There has been a controversy that whether the GMF should be banned.
On one side are the GMF supporters,who suggestion GMF has been no sign of major health or environmental problems. This kind of food has many advantages:increase crop yields, reduce production costs,enhance the ability of anti-virus and so on. GMF is usually cheaper and easier to plant than traditional food,in this way,we can get more people to eat and live. On the other are the opponents,who believe that GMF is harmful to our health because it's potential threat,such as some species may be affected by the drift of genes,GMF may cause allergic reactions. So,we should not promote and eat GMF.
In my point of view,GMF is a double-edged sword. Mature GMF can benefit mankind and reduce hunger,but we should take a cautious attitude to the immature GMF.
第二篇:《关于转基因的英语作文》
Recently, a debate about genetically modified foods between Fang Zhouzi and Cui Yongyuan has attracted many people’s eyes.
Fang appealed to people to come and enjoy genetically modified foods at micro-blogging which he thought is no harm towards human. Of course, this is not only his idea. It represents part of human who have great confidence and determination to make GM food become popular. Meanwhile, Cui’s question represents the worry and anxiety of the general public on GM, because no one can guarantee what will happen if people eat genetically modified foods for a long time. Such debate has both been in China and international. This time, the two celebrities put this issue in front of people again , I think we have to get more knowledge about it.
Firstly, genetically modified (gm) refers to the artificial separation (人工分离) and modified genes （修饰过的基因） imported into the purpose of the genome of the organism, so as to achieve the purpose of the modified organisms. Genetically modified (gm) is generally done by sexual reproduction. People often say "genetic engineering", "genetic engineering"（基因工程）, "genetic transformation"（遗传转化） are synonymous with genetically modified (gm). And then the genetically modified foods are produced in such way.
Then let’s look back to the history. In the early 1990s , the first genetically modified foods was produced in the United States that was a fresh tomato. Since then genetically modified foods become more and more popular. In March 2000, the cloned pigs were born. Followed, whether to eat genetically modified food becomes a debate both in Europe and America. According to the statistics , the U.S. Food and Drug Administration (食品和药物管理局) has identified 43 kinds of genetically modified varieties which makes The United States the largest country in genetically modified foods. In America, 60% of the processed foods contain genetically modified ingredients, including 90% of soybean, 50% of corn, and wheat are transgenic. There is not much difference between genetically modified foods and ordinary food, but genetically modified plants and animals have a distinct advantage, such like high-yield(高产) , insect resistance（抗虫）, anti-viral（抗病毒） and anti- herbicide（抗除草剂）. What I have to say is that with the application of transgenic technology the food shortage problem has been solved to some extent, the use of pesticide has been reduced, and the environmental pollution can also be avoided.
From the above, we may think the U.S. seems to advocate eating genetically modified foods. But it is undeniable that even in the United States, the debate around the genetically modified food has not been eliminated. Japan has even promoted organic foods vigorously to try to reduce genetically modified food. Europe has also adopted a strict market access system. Even in the United States where extremely reassure for genetically modified food, there are no direct transgenic technology for human staple food.{关于基因的作文}.
Although genetically modified foods have many advantages, there are also many studies showing that genetically modified foods have many flaws. In December 22, 2009, the Supreme Council of the French biotechnology (法国生物技术最高委员会) declared that cultivation of genetically modified maize is " more harm than good ."In the end of 2009, the U.S. Department of Health（美国卫生部）made a science paper that genetically modified foods can cause damage to internal organs. In May 2009, American Institute of Environmental Medicine (美国环境医学学会) issued a statement strongly to recommend
people not to eat genetically modified and educate the communities to avoid eating genetically modified foods.
第三篇:《人教版八年级下册三单元作文：基因密码破译之后……》
人教版八年级下册三单元作文：基因密码破译之后…… 自从老夫我听到人类破译了人的基因密码之后，就开始操心这脆弱得如一个西瓜的星球。已经有六十亿人口的人类社会，最可怕的问题莫过于资源的供应少于人口的享用，我一方面为人类科学的进步而自豪，可我又生怕人类因破译了基因密码而遭受毁灭。
依照人的基因密码，人对自身生命规律的控制那可就像泥人张玩泥人一样随意了。捏个美，捏个丑，捏成葫芦捏成瓢，捏棵千古参天大树，捏个春生秋灭的小草，都是随心所欲之事。这世上若真有那么一些人能活到千岁，那岂不是人类制出了一批活妖精。它们的存在，可比人们用幻想造出几个神仙来可怕得多。当然，破译人类基因和控制了人类基因这完全是两回事，它绝不会像捏泥人那么简单，只要拜师，就能学到手艺，就能塑造出个老寿星来。别说目前人类还不能把基因密码的实用技术运用于实践，就是能运用了，谁敢运用？首先用给谁？这可是一个既恐怖又充满了诱惑的事情。
如果不能让全球六十亿人口同时享用这一科学成果，而是百分之一、百分之二，这个指标怎么分配？是联合国大会表决，还是人权组织决定？是由各国总统拍板，还是由民主投票决定？是先用在科学家身上，还是先用到影星、球星身上？是先让贵族享受，还是先让普通民众接受试验？
生命短暂其实对平民百姓并没什么不好，只有谁都找不到长生不死的灵丹妙药，才能保证人们在生命面前有平等的权利。自从有了人类以来，无论你人分几等，官论几品，但是生命历程却从不厚此薄彼、嫌贫爱富，这个最原始、最基本的平等，才使得芸芸众生虽然平平淡淡一辈子，可心理上还算有了平衡点那就是谁都得面对百年之内的死亡。
一旦千年长寿的待遇若只能被少部分人享用，世界不大乱那才怪呢。这可不是万两黄金，你有权，你就贪，法律漏了你的网，阎王爷早晚也收编你。如今有人能逃避死亡，而且是让少数人享受这个由人类集体创造的科技成果，那么绝大多数短命鬼就会觉得人世间已彻底没有了平等，那就人为地去捣毁这个世界比活着还舒服了。据我这个不懂科学的人推断，毁掉一个千年之命比培植一个千年之命更容易让广大百姓掌握和运用吧。
生命的长短还是人类不能随意控制好，生命之所以珍贵是因为它是有长度的，它对人是最公平的。这个基本平等是人类社会稳定的基础。一旦让腐败和强权者贪污了长寿的密码，这个世界可就再难找到好人了。
第四篇:《英语作文-转基因食品-Should Genetically-modified Food be Stopped》
班级：A17班 姓名： 学号：
Should Genetically-modified Food be Stopped?
Nowadays, the number of genetically-modified food is steadily increasing. There is an argument that whether this kind of food should be stopped . As far as I am concerned , genetically-modified food should not be stopped.
Firstly, there is necessity for genetically-modified food to exist. Genetically-modified food belongs to food. The world is lack of resources. Every day, millions of people around the world eat only the bare minimum of food to keep themselves alive. They will be very grateful for having this kind of food to survive.{关于基因的作文}.
Secondly, it is easier for us to plant genetically-modified food. At the same time, the production cost is also greatly reduced. As a result ,food prices will increasingly low. There is no doubt that it is good news for consumers.
Thirdly, It will reduce the use of pesticides and then avoid the pollution of the environment.
In addition, genetically-modified food can bring us many other benefits, for example, increasing food nutrition, increasing the types of food and so on.
However，although genetically-modified food have so many advantages, some people still insist that they should never eat
genetically-modified food. They are afraid of potential threat that this kind of food will be harm to their health. In fact ,genetically-modified food has passed the the strict test of international organizations. It is safe. There has been no evidence to prove that genetically-modified food is harm to humans so far. To some extent, we can consider this kind of food to be perfectly safe. As you know, at present there is a lot of genetically-modified food in the market, such us genetically-modified soybean ,Transgenic papaya and so on. Many people have eaten this kind of food for some years, but we have not exactly confirmed that some one falls ill after eating genetically-modified food.So there is no need to worry much about the safety problem. We can eat them as we like.
All in all, we should not stop genetically-modified food. But, this kind of food may cause some people’s allergic reactions. So in the process of producing genetically-modified food, we should eliminate the genes which can cause allergic reactions and do the digestion experiment in order to avoid the harm to human body.
第五篇:《雅思6分作文(转基因食品)》
More and more farmers and food manufacturers are genetically modifying their crops to reduce susceptibility to disease, improve flavor, and reduce costs. Do you think genetically modifying foods is a good idea? Why or why not? Use specific reasons and examples to support your position.
Sample 6 Score{关于基因的作文}.
A few decades ago, manipulating genes in people, plants, and animals was just
science fiction. Today, it’s a reality, and genetic modification may have many
positive applications in the future, including the eradication of many hereditary
diseases. But like most scientific and technological advances, the genetic
modification of organisms for our food supply can be as dangerous as it is
beneficial. Because of the potential dangers of this technology, I think genetically{关于基因的作文}.
altering plants and animals in the food supply is a practice that should
be very tightly controlled and carefully studied before it is an accepted and
common practice. Unfortunately, it may already be too late for that.
Many people don’t even realize that many of their foods are genetically
modified organisms (GMOs). GMOs are already prevalent in supermarkets
and grocery stores across the country, but manufacturers are not
required to label foods as having been made from GMOs. As a result, millions
of Americans purchase and eat GMOs every day without even knowing
it. Yet we don’t even know if GMOs are harmful to our health. We
don’t really know how GMOs may affect our bodies or our ecosystem.
When we mess with DNA, we may be making changes that have all sorts
of dangerous repercussions, including some that we may not even realize
for several generations.
One of the main concerns about GMOs is the unpredictability of the
behavior of altered genes and of the bacteria, plants, and animals that interact
with the altered organism. For example, a crop of corn genetically modified
to be less susceptible to a particular insect may take on other unwanted
characteristics due to the change. It may, for example, become more susceptible
to another disease, or it could develop a tougher skin on its kernels,
or it could decrease the crop’s ability to produce vitamin E.
More frightening is the domino effect of genetically modifying foods.
Any change in an organism’s DNA has the potential to affect not only the
organism but also anything that feeds off of it, including us. How do we
know how GMOs might affect us on a microscopic, genetic level? We don’t
know, and can’t know, without years of studies that track all sorts of potential
outcomes over several generations.
Another fear is that transferred genes may escape from one organism into{关于基因的作文}.
another. For example, imagine that Strain A of sweet peas was altered by
adding a gene that would increase its sugar production. Through cross-pollination,
this altered genetic code could enter other strains and slowly (or
quickly) infect the entire sub-species. If the alteration was beneficial, this
could be a good thing. But the altered gene might not act the same way in{关于基因的作文}.
all varieties, and the change may not be a good thing in the first place,
and/or it may have unintended consequences.
Genetically modifying foods is a practice that has been driven by the desire to make more food available more quickly and more cheaply than
ever before. This attitude puts profit first and consumers and the environment last, and that is simply dangerous. The agribusiness needs to slow down and stop selling us GMOs until their safety is certain.
