转基因食品的利与弊英语作文
A. 英语作文是关于转基因食品的进口的赞同与反对最后是自己的观点
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(遗传物质). Foods from plants grown in this way are called genetically modified foods(转基因食品), 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(准备), 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.
B. 转基因食品的好处与坏处,最好是英文的~
转基因食品?当“基因”这一词汇渐渐成为流行语时,颇有争议的转基因食品也走进了我们的生活,摆上了老百姓的餐桌。近年来,有关转基因食品是否会对人体健康造成危害的争议日趋激烈,引起了全世界公众的高度关注。但是在我国,转基因食品对大多数老百姓而言,似乎仍然是陌生而遥远的。什么是转基因食品基因是控制生物性状的最基本单位,记录着生物生殖繁衍的遗传信息。通过修改基因能改变一个有机体的部分或全部特征。转基因食品就是移动动植物的基因并加以改变,制造出具备新特征的食品种类。譬如,利用生物技术将某些动物的基因转移到其他物种上去,通过改造生物的遗传组织,使其出现原来并不具备的特征,这些转变可以按照人类所需要的目标来完成。例如,人们可以用鲜鱼的基因帮助西红柿、草莓等普通植物来抵御寒冷;把某些细菌的基因接入玉米、大豆的植株中,就可以更好地保护它们不受害虫的侵袭。而以这些转基因生物为原料加工生产的食品就是转基因食品。转基因食品安全吗转基因食品是从实验室中走出来的,是人工制造出来的。在讲究自然、生态、健康消费热潮的今天,转基因食品被不少人视为“异类”,把它打入“冷宫”,可以说,转基因食品的安全性备受人们的质疑。从目前的情况看,转基因产品确实有些方面还说不清楚。比如,食品安全方面有一些让人怀疑的地方。虽然自从美国第一批转基因西红柿上市以来,全球约有2亿多人食用过数千种转基因食品,5年多来尚未报道过一例食品安全事件。我国进口转基因大豆较多,据估计约有一半的大豆色拉油中含有转基因成分,亦没有出现任何问题,但国外的有些报道仍然值得关注。据英国媒体报道,1998年秋,英国一位研究人员在电视节目中公布了他的实验成果:用转基因马铃薯饲养大鼠,引起了大鼠器官的生长异常,体重减轻,免疫系统遭到破坏。这件事情,虽然后来被英国皇家学会组织的专门评审中定调为共有6项缺陷,但仍然引起了人们对转基因食品的怀疑。其实,根据国际通行的生物安全评价办法,按照转基因生物对人类、动植物、微生态和生态环境的危害程度,农业转基因生物可分为4个等级:即安全等级Ⅰ(尚不存在危险);安全等级Ⅱ(具有低度危险);安全等级Ⅲ(具有中度危险);安全等级Ⅳ(具有高度危险)。而在转基因食品的制造过程中,要经过严格的评定审核,务必要使其达到不存在危险的程度。可见,对转基因食品的安全措施是有的,只要坚持“预先防范”的原则,完全可以确保转基因食品是安全的。另据介绍,转基因食品的外表和天然食品没有多大差别,它的味道与天然食品相似,或许更好一些。有的转基因食品中添加了提高蛋白质、维生素含量的基因,还能给人体补充适量的营养。可以这样说,转基因食品并不可怕,我们早就享受了杂交水稻煮出的饭香。关键在于监管争论不下,阻挡不住,转基因食品已经摆在了消费者面前,说不定,你家的餐桌上就有。而适应这一形势,我国《农业转基因生物标识管理办法》也开始实施。我国列入第一批标识管理的农业转基因生物有大豆种子、大豆、大豆粉、大豆油、豆粕、玉米种子、玉米、玉米油、玉米粉、油菜种子、油菜子油、油菜子粕、棉花种子、鲜蕃茄、蕃茄酱。按照规定,消费者在购买转基因食品时,可向经营者询问商品的性能、质地、有效期限、生产厂商等问题,经营者有义务有责任向消费者说明情况。而生产厂商则要在标牌上把产品的基本情况介绍清楚。有关专家提醒,对制造商不愿粘贴标识的转基因产品,消费者不要急于购买,而一旦购买时则须多问。消费者如果“吃”进了没有粘贴标识的转基因食品,可以向卫生、工商等职能部门举报,根据《农业转基因生物安全管理条例》的要求,对违反其规定的,可以没收非法销售的产品和违法所得,并处以1万元以上5万元以下的罚款。食品是人们赖以生存的最基本必需品,对转基因食品,消费者可要睁大眼睛啊!
C. 关于对转基因食物的优点和缺点及自己看法的英语作文
这就是关于转基因食品优缺点的作文: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. 希望会对你有帮助吧,谢谢!
D. 转基因食品的优缺点英文作文
The advantages of genetically modified food: it can increase crop yield; rece proction cost; enhance the ability of crop to resist insect and virus; improve the storage resistance of agricultural procts.
For example: genetically modified food - potatoes; shorten the time of crop development; get rid of the supply of four seasons; break the boundaries of species, cultivate new species, and proce food that is concive to human health.
Disadvantages of genetically modified food: the so-called increase in proction is not affected by the environment. If there is a natural disaster of rain and snow, it may also rece proction even more severely. At the same time, in the process of cultivation, genetically modified crops may evolve into farmland weeds; other species may be affected by gene rafting; genetically modified food may cause allergies, etc

2、食品安全
进退两难的境地和两面性的特征,基因作物在舆论界引发争议不足为怪。但在同属发达世界的大西洋两岸,转基因技术的待遇迥然不同却是一种耐人寻味的现象。当美国40%的农田种植了经过基因改良的作物、消费者大都泰然自若地购买转基因食品时,此类食品在欧洲何以遭遇一浪高过一浪的喊打之声?从直接社会背景看,目前欧洲流行“转基因恐惧症”情有可原。从1986年英国发现疯牛病,到今年比利时污染鸡查出致癌的二恶英和可口可乐在法国导致儿童溶血症,欧洲人对食品安全颇有些风声鹤唳,关于转基因食品可能危害人类健康的假设如条件反射一般让他们闻而生畏。
运用基因工程技术,不但可以培养优质、高产、抗性好的农作物及畜、禽新品种,还可以培养出具有特殊用途的动、植物。
