第一篇:转基因食品现状(英文演讲presentation)演讲稿.
Hi!Everyone!Today.I will show you something about GM foods.The full name that GM foods is Genetically Modified Foods.This is a hot topic.let’ s start to the present situation of GM foods.According to researchers.People who feel intimidated by math may be less able to understand messages about genetically modified foods and other health-related information.Parrott Distinguished Professor of Communication Arts and Sciences and Health Policy and Administration.said :“My goal is to help people make informed decisions and to do that, they need to understand and comprehend messages,Food policy, in particular, interests me because having enough food to feed people is a really big issue that we're facing.” Scientists argue that genetically modified foods are safe for consumption and overregulated.the overregulation of GM crops actually hurts the environment, reduces global health and burdens the consumer.(switchFarmers have witnessed the advantages of GM crops firsthand through increases in their yields and profit, and decreases in their labor, energy consumption, pesticide use and greenhouse gas emissions.Farmers growing genetically modified rice in field trials in China report higher crop yields, reduced pesticide use and fewer pesticide-related health problems, according to a study by researchers in China and at Rutgers University and the University of California, Davis.Measured on a per hectare(2.471 acres basis, the quantity and cost of pesticides applied to the conventional rice was 8 to 10 times as high as that applied to the insect-resistant genetically modified rice.“What we found was when genes for enhancing the amount of antioxidants and vitamin C in fresh produce were transferred by intragenic methods, consumers are willing to pay 25 percent more than for the plain product(with no enhancements.That is a sizable increase,” said Huffman, distinguished professor of economics.(switch The basic idea is
that when consumers saw that the intragenic produce had elevated healthful attributes, they were willing to pay more for them.But ,Consumers were not willing to pay more if those enhancements were introduced through transgenic methods.In my opinion, GM food have good prospects.To eliminate the misunderstanding on GM food, scientists should strengthen communication with people.With simple and easy to understand words, tell us that GM food is not so terrible.One day, GM food will benefit mankind.
第二篇:My Presentation(英文演讲稿)
My presentation is about PPT.I think making a good PPT is a difficult work for us.I hope my presentation can help you.What do you think is the most important thing in a PPT.Is it font, color, template, layout or animation? Admittedly, they are all very important, but I think the most important is logic.If you make PPT with orders, it will make it easier for people to understand your ideas.Before you start making a PPT, you should have to first grasp the whole idea and system.This section describes the logical step PPT idea.The first step: Scenario Analysis Before making PPT, you have to first consider the audience, theme, occasion, purpose and speech time of the PPT Step two: style established After understanding , make sure your PPT style.Are you going to make it official, Business, Professional, Easy, or Simple.Don’t have any ideas? You decide everything!The third step: Material collected The material collected here does not refer to the production process of the image material, But you can enrich the content of your PPT good content + good design creates a good PPT Step Four: structural organization Will you collect first-hand material for analysis integration,? Which can serve you to extract the material point of view? These materials are used in series with the main line, so that it can show a clear point of view, sort of storytelling in a logical order, Step five: a collection of audit Review your logic to integrate ideas and perspectives clarity, concise text based, and image visualization.Each page outlines the content and layout of PPT
Short cut your logic mind into a keyword or a sentence then machining it including your beautiful word and idea, last, let your idea easy to understand.For example: Too many words make the audience to read the content on the PPT and ignore the speaker itself, we want to optimize the logic of this PPT.See, it is clean and it let you shocked

转基因食品之争演讲稿
近年来,随着人们生活水平的提高,绿色、健康消费成为很
多市民购物时的首选。新概念食品的层出不穷,让消费者有些目不暇
接,其中的转基因食品更是人们热议的重点,“它”真的安全吗?“它”
真的能够放心食用吗?
转基因食物已经在不知不觉间进入我们的生活。而对“转基
因”这个概念,我们却知之甚少,于是,各种争论和抵制一直在出现,从没有停止。让我们来看几幅图片。
那么,转基因食物,究竟是天使还是魔鬼呢?首先,让我们
来了解何为转基因食品。
转基因食品是利用现代分子生物技术,将某些生物的基因
转移到其他物种中去,改造生物的遗传物质,使其在形状、营养
品质、消费品质等方面向人们所需要的目标转变。
以转基因生物为直接食品或为原料加工生产的食品就是“转基因
食品”。(人们怕吃转基因食品,为什么,作说明)
一件事物,既然它出现了,那么它一定是有用的,有存在的必要性。转基因食品它有什么优点呢?
可增加作物单位面积产量;
可以降低生产成本;
通过转基因技术可增强作物抗虫害、抗病毒等的能力;提高农产品的耐贮性,延长保鲜期,满足人民生活水平日益提高的需求;
可使农作物开发的时间大为缩短;
可以摆脱季节、气候的影响,四季低成本供应;
打破物种界限,不断培植新物种,生产出有利于人类健康的食品。
我国历代领导人也对这种先进的技术十分重视,历年的中央一号文件也对此大力支持,它功能强,而且受官方支持,为什么会受到
争议呢?因为我们还不能完全控制它!自从沃森和克里克发现了
DNA的双螺旋结构,人类就从与各生物平等的角色上升到了造物主的层次!我们变得可以创造物种,然而我们却不能完全控制我们所创
造的东西,我们需要对大自然有所敬畏。譬如美国的超级杂草,新疆的棉花爆发虫害。一些本不可能出现的基因片段却在人类的操纵下插
入某些生物造成危害。(在此做大量说明)
与转基因食品一样饱受争议的生物技术,克隆技术(简单介绍,大规模生产优质肉牛,器官移植),它的出现一样饱受争议,但是更
多的却是伦理问题,美国政府就这个问题专门拨款3亿美元成立伦理
研究协会,专门研究伦理问题。
这或许对我们研究的问题有所启发,我们需要对大自然保持敬
畏,需要一批负责任的科学家,而不是急功近利的政客。当然,随着
现代生物技术的发展及应用,尤其是转基因产品越来越多地涌入到人
们的日常生活,人们的生物技术恐惧感在日益增加。其中,社会文化
因素增强了这种恐惧心理。我们有必要从文化视角审视正在蔓延的生
物技术恐惧心理,分析此种心理的来源与扩散,抚慰人们的脆弱心灵,做好生物风险的防范工作,促使生物技术与社会的协同发展。

第五篇:英文presentation关于国庆节
The Chinese National Day
The Chinese National Day is original from the 1stOctober, 1949 when the Chinese Communist Party fought against the Nationalist Party and finally ended the four years’ civil war.From that day, all the Chinese, namely the poor people suffered from the governing by kings and Japanese invasion, achieved the freedom they deserved.In every year, all the Chinese people will celebrate this historical moment for the independence of our country.During this national holiday,people will enjoy a nice trip or a family party.Especially, more shops will present various activitiesfor sale.I think this festival is a mark for our Chinese to be free and live a life as we want and hope.It is a significant and historical moment for the Chinese people.
