Good afternoon, everyone!I am very glad to have a speech here.My name is ……, and my major is …….…….is my hometown, a famous city in the Three Kingdoms, and it is rich in rice and fish.I graduated from …….University in ……., and now, I am studying in ……..In my spare time, I like to play computer games, surf on line, or travel with friends and sometimes I like being alone and doing nothing.My topic is GMF and Health, before my topic, I want to ask you some questions: do you know what the GMF is? Do you ever eat in KFC or McDonald's? You may be surprised at what is the relationship between them.It is said that the most foods in KFC and McDonald's are GMF.This chicken with six legs and six wings is made for food in McDonald's.The topic of GMF is becoming more and more popular recently.Scientists embed the special gene into plants to get the genetically-modified crops which usually have higher yield and look more attractive than the common crops by genetic engineering technology.Besides, the GM crops are more resistant to diseases and insects.In the other words, they can reduce the cost to some extent.As a result, the GM crops become popular with famers and businemen, and then the GMF emerges in the market.Such as beans, corn, rice, chili(辣椒), and so on.What is more, the supporters think that it is hopeful to solve the food crisis, and the GMF is healthier than common food.However, the GM crops are not natural plants, and they are forced to change themselves by human.What is worse, the development of GM technology is immature, and no one knows what the result it will cause.So a great number of people object to the GMF.For example, they think the new strange creatures which made by GM may disturb the food chain, and even will change the world which we are living now and threaten the survival of human beings.For another thing, the GMF may pose health risk to consumers.First of all, it may cause unpredictable mutation(突变)in the GMF, and then produce new and stronger poison.Besides, the special gene with resistant to diseases may make the drug-resistant bacteria and cause new diseases.Thirdly, the allergies may become more frequently.For example, a man who has a shrimp(虾)allergy rather than fish.It may be very unfortunately for him to eat a fish and get allergy because the fish which he eats is modified with a special gene in shrimp.Lastly, the nutritive value of GMF will be reduced because of the remove of some substances which we do not know whether they are neceary to our bodies.In my opinion, the GMF may be an effective way to solve the food crisis in the future, but before extent and commercialize it we should ensure it is safe enough, rather than apply it with so much unpredictable.Just as what Yuan Longping said: “We should hold a scientific and cautious attitude to GMF, and try to bring the advantages of GM technology into full play, reduce the disadvantages to the minimum at the same time.In that case, we will definitely make a better use of the GM technology and enjoy a better-off life, rather than refuse it absolutely.”
That is all my speech, thank you!
