M5U3写作材料(与本单元话题GM food and cloning有关)目前，农业部批准了两种转基因水稻的安全证书，再一次引起了人们对转基因食品的讨论。以下是某网站收集的关于转基因食品的看法，请你根据下表内容给The New York Times写一封信介绍调查结果并简单发表个人看法。反对方1 可能伤害周边的植物和昆虫2 对人体有潜在的危害3 转基因农作物产量并不比农作物产量高支持方1. 可以解决粮食短缺问题2. 减少农药使用3. 节省生产成本，降低食物售价 No.17, Puming Road Shanghai, China September 12, 2010620 Eighth AvenueNew York, USADear Editor, I am writing to tell you about the recent debate about GM food in China. People against it hold the opinion that GM food will endanger the surrounding plants and some insects . Worse still, some people only care about the profits it brings and neglect the fact that it can put peoples health in danger. Last, production of GM crops is no higher than that of regular crops. So GM food will end up in failure. Despite the fears and worries raised by opponents of GM food, its supporters think that GM food is of great value. For one thing, it can not only help people fight against food shortage, but also reduce the use of pesticides. For another, GM food requires less energy, water, and soil, thus reducing production costs as well as food prices. In my opinion, GM food will play an important role in relieving peoples worry about food shortage in the long run. Though it may have some disadvantages, we can not give up eating for fear of choking. Best wishes! Sincerely yours, Li Jun近年来，种植转基因水稻逐渐在我国展开。你班同学就是否应该种植转基因水稻进行了讨论。请你根据下表用英语写一篇短文，介绍讨论结果并简要谈谈个人看法。30%赞成1.不易遭受病虫害，减少农药的使用，对消费者和环境有好处2.产量高，有利于农民提高收入70%反对1.大米是中国人的主粮，安全性未知，不能冒险2.转基因种子适应气候能力弱你的看法？Recently my class has held a discussion about whether GM rice should be grown in China. Different students hold different opinions. 30% of the students are in favor of the idea. First of all, GM rice is better able to defend themselves against insects and diseases, so it requires fewer pesticides, which is beneficial to consumers and the environment. Secondly, the output of GM rice is higher than that of ordinary rice, which can help to increase farmers income. However, 70% of the students dont think China should try out GM rice. Firstly, rice is the main food of Chinese people. We cant take any risks as long as the safety of GM rice is not certain. Secondly, GM seeds are slow at getting used to climate changes, which may result in a sharp drop in output. As for me, I think we should be careful with GM rice. There is little evidence that GM food is harmful to health, but this does not mean we can ignore the possible threat.现代科学杂志向你约稿, 希望你写一篇短文, 介绍20世纪最伟大的科学成就。你打算写关于克隆技术的短文.利处弊处1. 改良农作物的基因2. 克隆生物组织及器官,挽救病人生命及治疗疾病3. 克隆技术拯救濒危动物;1.克隆人的身份难以确定,伦理上造成混乱2.克隆人技术被滥用,3.诱发新型疾病的广泛传播,这对人类生存不利.美总统布什:人的生命不应为另个人的利益所创造或毁灭.你的观点: 1: (至少两点) 2: .字数:150左右; 混乱:confusion 伦理上: ethicallyPossible version:The modern technological breakthrough of cloning is raising concern worldwide / has caused much debate worldwide.The cloning technology can help produce genetically improved crops. Also, the cloned tissues and organs can be used to save lives and cure diseases . Besides, we can save endangered species using cloning technology. However, the scientific breakthrough can also bring disadvantages. The identity of the clone may be hard to determine/identify and may cause confusion ethically. Whats worse, cloning technology could be improperly used by terrorists. Clones may even introduce new diseases , which is harmful to human survival. President Bush once said, “ Life should not be created or destroyed for the benefit of other people” and many agree that cloning human embryos shows no respect for human life.Every coin has two sides and cloning technology isnt an exception. From my point of view, cloning should be focused on improving food quantities for all people and rescuing endangered species. But we should be cautious about cloning human embyros since we havent enough knowledge about cloning so far. Only when we use the technology properly can it benefit mankind in the long term.

Recently my classmates and I have done some research. We went online and to the library to find as much information as possible about food from cloned animals. Besides, we also interviewed many people about their ideas of the food from cloned animals. The result shows that many people doubt whether food from cloned animals is really safe for us to eat , especially in the long term since cloning is quite a new scientific technology, Cloning is not very cheap at present, so most people will not be able to afford to buy food from cloned animals in supermarkets.
