篇一:《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.

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.

篇二:《关于转基因食品的主题阅读阅读答案》

关于转基因食品的主题阅读（14分）

【材料一】

转基因作物的种植越来越广泛。1990年世界上还没有人正式种植转基因作物。1999年种植面积达4000万公顷。2011年飚升至1.6亿公顷，占全球耕地的10％，相当于中国可耕地面积的1.3倍。

人们对转基因食品的态度存在很大差异。美国和加拿大民众对基因改良食物的接受程度比较高。市场上的一些加工食品如软饮料、啤酒和早餐麦片等都已含有基因改良作物的成分，并没有遇到多少质疑。欧洲的情况却不一样。一项民意调查显示，79%的英国民众反对试种基因改良作物。法国农民甚至把牛粪倾倒到一些麦当劳快餐店门前，抗议他们出售的牛肉面包和土豆中含有转基因食物。

关于转基因食品，目前争论主要集中在三个方面：

第一，反对者认为，转基因违反自然，因而是有害的。支持者则反驳说，现今的各种庄稼早已不是原始品种，否则人们吃的蔬菜就该跟动物吃的草一样。{以转基因主题的作文}.

第二，反对者质疑，植物里引入具有抗除草剂或毒杀害虫功能的基因后，它们所提供的食物对人体是否依然安全。支持者强调，迄今为止并无够资格的研究机构发现转基因食品有危害人体健康的证据。

第三，反对者认为，过于勿忙地推广转基因植物可能影响农业和生态环境。推广抗除草剂的转基因作物可能助长农民过量使用除草剂，从而使一些非主要作物受到伤害甚至灭绝。美国渔类和野生动物管理署已发现有74种植物品种受除草剂影响而濒临灭绝。有特殊功能的基因有可能“流窜”到相近的野生植物品系中去，使之具转基因植物的能力而难以控制。有的生物技术公司为了保护自己的知识产权，对销售给农民的转基因种子作了“绝育”处理。美国印地安那大学生物系副教授玛莎?克劳奇的研究表明，这种绝育基因有可能在无意中使其他作物也变成不育。支持者则指出，农业生产本身是一种有损环境的活动，转基因作物对环境的损害不会比传统农业更大。植物自身具备了抗虫能力，农民可以减少喷洒杀虫剂，对环境和生物保护是有利的。

【材料二】

复旦大学生命科学院蒯本科教授说，转基因食品是一个世界性的问题。其实任何东西都存在一个安全性的问题。就像开发药品一样，药品从开发开始到最后成功，在某个环节上都可能被淘汰掉。转基因只是科学家在实验室中，把动植物的基因加以改变，再制造出具备新特征的动植物种类的一种手段，它本身并不代表有害或是没害，好或是不好。转基因食品是不是有利，取决于转什么基因，或者基因转到什么食品里。

【材料三】

我国《农业转基因生物标识管理办法》规定：在中华人民共和国境内销售列入农业转基因生物标识目录的农业转基因生物，应当进行标识；未标识和不按规定标识的，不得进口或销售。

小题1:根据相关材料回答，什么叫转基因生物？什么叫转基因食品？（3分）

小题2:反对者认为“过于勿忙地推广转基因植物可能影响农业和生态环境”的理由是什么？（4分）

小题3:在某超市食用油摊位，一位老太太问旁边的营业员转基因油对健康有没有副作用。假如你是这位营业员，根据相关材料，该如何向老太太解释？（4分）

小题4:你是否赞成国家的转基因生物产品标识制度？为什么？（3分）

参考答案：

小题1:科学家在实验室中，把生物的基因加以改变，再制造出具备新特征的生物叫转基{以转基因主题的作文}.

因生物（2分）。用转基因生物制作的食品叫转基因食品（1分）。

小题2:推广抗除草剂的转基因作物可能助长农民过量使用除草剂，从而使一些非主要作物受到伤害甚至灭绝（2分）。有特殊功能的基因有可能“流窜”到相近的野生植物品系中去，使之具转基因植物的能力而难以控制（2分）。

小题3:老太太，虽然转基因食品对健康有没有副作用还有争论，但反对者无法提供转基因食品有害健康的可靠证据，目前这类食品的生产和销售的数量十分巨大，而且是国家允许的，所以您不用过分担心它的安全性问题。

小题4:如：我赞成国家实施转基因生物产品标识制度。因为人们对于转基因生物产品的安全性还有很多争议，所以应该尊重消费者的知情权和选择权。

小题1:试题分析：审题后寻找答题的范围，我们可以看到材料二中的关键信息“转基因只是科学家在实验室中，把动植物的基因加以改变，再制造出具备新特征的动植物种类的一种手段，它本身并不代表有害或是没害，好或是不好”，由此可知“转基因生物”即：科学家在实验室中，把生物的基因加以改变，再制造出具备新特征的生物。同理“转基因食品”就是用转基因生物制作的食品叫转基因食品。

小题2:试题分析：“过于勿忙地推广转基因植物可能影响农业和生态环境”出自材料一中的中间一段，题干中的语句是该段的中心句，即该语段的内容即是原因，在语段中提取即可。

小题3:试题分析：这是一道口语交际题，但是的内容必须根据选文的内容来回答。因此我们首先要理解选文的内容，并从中找到更切合本题题意的关键语句，如“它本身并不代表有害或是没害，好或是不好。转基因食品是不是有利，取决于转什么基因，或者基因转到什么食品里”等。因为是口语交际题，所以一要注意有称呼，二要注意有针对性，三要注意说话时的用词与语气。

小题4:试题分析：首先要表明自己的态度、观点，一般应是赞成的，因为转基因食品有害还有无害的争议很厉害，“未标识和不按规定标识的，不得进口或销售”这是对食品安全的一种有效的保障措施，是对人民的健康有力的。

篇三:《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.

Genetically engineered foods have attracted a large amount of media attention in recent years and continue to do so. Despite this, the general public remains largely unaware of what genetically engineered foods actually is or what advantages and disadvantages the technology has to offer.Two main areas of concern have emerged, namely risk to the environment and risk to human health.And I think that genetically engineered foods should be boycotted by restaurant owners, supermarket owners, consumers in general in order to eliminate this potential danger.

Firstly, the genetically engineered foods may do harm to individuals and the animals. For example, some genetically engineered crops’ gene is transferred from other plants which are quite different, and this makes them resistant to insects. Since this special crop are resistant to insects, they may be also poisonous to certain animals, and even people. It can affect other species through genetic drift, threat to the biodiversity.

Secondly, there is a potential danger. Many children in the US and Europe have developed life-threatening allergies to peanuts and other foods. There is a possibility

that introducing a gene into a plant may create a new allergen or cause an allergic reaction in susceptible individuals. There is a growing concern that introducing foreign genes into food plants may have an unexpected and negative impact on human health. A recent article examined the effects of genetically engineered potatoes on the digestive tract in rats. This study claimed that there were appreciable differences in the intestines of rats fed genetically engineered potatoes and rats fed unmodified potatoes.

There must be more disadvantages responsible for what I suggest. So for the sake of the ecosystem and our safety, the genetically engineered foods should be abandoned.And we must proceed with caution to avoid causing unintended harm to human health and the environment as a result of our enthusiasm for this powerful technology.

Genetically Modified food

With the science and technology expanding day by day,we can get and experience more and more things which have never existed

before,such as plane,car and genetically modified food.The planes and cars can let us be more convenient in our daily life.However,so far we still do not clearly know all the aspects of genetically modified food.Do they damage to our healthy?

So what is the genetically modified food?It is a kind of food that people apply modern molecular biotechnology,transfer some biological gene to other species, transform the genetic material of living

things,change the shape, nutritional quality, consumer quality to the target of people's needs.So from the definition of GMF,we can

know it happened for people's needs.We can have more options to cook and eat,and it also can save our money because this kind of food is usually cheaper and easier to plant than others.Originally, it is good for our life.

While,almost 50 percent of the whole people in China believe that the genetically modified food is not safe to our healthy,but what is the fun thing is most of them don't know how the genetically modified food damage their healthy.They just are deeply misunderstanding and even have repellent psychology because of the long-time negative public opinion.{以转基因主题的作文}.

Of course,in our country,the new grain law have same more rigorous rules.For example,the genetically modified seeds' scientific research,experiments,productions,sales,imports and exports should be followed to the country's laws,and every individual person and unit are not allowed to imply genetically modified technology at principle grain cultivars without authorization.

So in my opinion,we should believe that the genetically modified technology can bring more advantage and less disadvantage to us.It becomes a tendency to eat genetically modified food.So we just be at ease to eat unless the productions are counterfeit and inferior and it is not qualified by the standard department.

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.

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.
