第一篇:轉基因食品現狀(英文演講presentation)演講稿.
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(英文演講稿)
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

轉基因食品之爭演講稿
近年來,隨著人們生活水平的提高,綠色、健康消費成為很
多市民購物時的首選。新概念食品的層出不窮,讓消費者有些目不暇
接,其中的轉基因食品更是人們熱議的重點,“它”真的安全嗎?“它”
真的能夠放心食用嗎?
轉基因食物已經在不知不覺間進入我們的生活。而對“轉基
因”這個概念,我們卻知之甚少,于是,各種爭論和抵制一直在出現,從沒有停止。讓我們來看幾幅圖片。
那么,轉基因食物,究竟是天使還是魔鬼呢?首先,讓我們
來了解何為轉基因食品。
轉基因食品是利用現代分子生物技術,將某些生物的基因
轉移到其他物種中去,改造生物的遺傳物質,使其在形狀、營養
品質、消費品質等方面向人們所需要的目標轉變。
以轉基因生物為直接食品或為原料加工生產的食品就是“轉基因
食品”。(人們怕吃轉基因食品,為什么,作說明)
一件事物,既然它出現了,那么它一定是有用的,有存在的必要性。轉基因食品它有什么優點呢?
可增加作物單位面積產量;
可以降低生產成本;
通過轉基因技術可增強作物抗蟲害、抗病毒等的能力;提高農產品的耐貯性,延長保鮮期,滿足人民生活水平日益提高的需求;
可使農作物開發的時間大為縮短;
可以擺脫季節、氣候的影響,四季低成本供應;
打破物種界限,不斷培植新物種,生產出有利于人類健康的食品。
我國歷代領導人也對這種先進的技術十分重視,歷年的中央一號文件也對此大力支持,它功能強,而且受官方支持,為什么會受到
爭議呢?因為我們還不能完全控制它!自從沃森和克里克發現了
DNA的雙螺旋結構,人類就從與各生物平等的角色上升到了造物主的層次!我們變得可以創造物種,然而我們卻不能完全控制我們所創
造的東西,我們需要對大自然有所敬畏。譬如美國的超級雜草,新疆的棉花爆發蟲害。一些本不可能出現的基因片段卻在人類的操縱下插
入某些生物造成危害。(在此做大量說明)
與轉基因食品一樣飽受爭議的生物技術,克隆技術(簡單介紹,大規模生產優質肉牛,器官移植),它的出現一樣飽受爭議,但是更
多的卻是倫理問題,美國政府就這個問題專門撥款3億美元成立倫理
研究協會,專門研究倫理問題。
這或許對我們研究的問題有所啟發,我們需要對大自然保持敬
畏,需要一批負責任的科學家,而不是急功近利的政客。當然,隨著
現代生物技術的發展及應用,尤其是轉基因產品越來越多地涌入到人
們的日常生活,人們的生物技術恐懼感在日益增加。其中,社會文化
因素增強了這種恐懼心理。我們有必要從文化視角審視正在蔓延的生
物技術恐懼心理,分析此種心理的來源與擴散,撫慰人們的脆弱心靈,做好生物風險的防范工作,促使生物技術與社會的協同發展。

第五篇:英文presentation關于國慶節
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.
