Advantages and disadvantages of GMF(Genetically Modified Food)Genetically modified foods is the food that is changed by the genetic engineering to fulfill humans’ content.Since genetically modified foods emerged in the 1980s, many scientists have conducted studies on this foods.As people’s understanding increase gradually, different opinions about the advantage and disadvantage of the foods come up.let’s start the debate

一、陈述观点阶段

正方一辩（丁）：Good afternoon, everyone!I think that genetically modified food is good for us , In today’s world, Scientists use biological technology to transfer genes from some biological sources to other species.And it would change genetic material of the crops which leads to positive traits, and better nutritional quality to satisfy human needs.We can use genetically modified organisms as a direct food or as raw materials to make food.反方方一辩（蒋）：Good afternoon, everyone!From the internet, we know that the genetically modified crops can evolve into farmland weeds itself;it can affect other species through genetic drift, threat to the biodiversity;also the genetically modified foods may produce allergic reaction and so on.邓：Genetically Modified Food can solve the problem of food shortage，reduce pesticide use, to avoid environmental pollution

马：Currently, Transgenic technology is still in the primary stage of the study, most people insist that food cultivated by this technology is unnatural, it maybe poisonous, can bring allergic reaction problem and threaten to the environment.丁：Genetically Modified Food save production costs, lower food prices，increase the types of food, improve food quality and increase food nutrition

蒋：genetically modified food has broken the balance of nature and it is unhealthy for us to eat too much.Having it, we may get a delicious taste, however we may reduce our body resistance, we may became more likely to get sick.邓：Genetically Modified Food improve the additional value，promote the production efficiency and drive the relevant industries

马：the natural food may be more suits for us, so, we should pay more attention to our health and refuse to genetically modified food.总结陈词：

Objectively speaking, each new thing has its own growing proce, We should use the objective critical and inclusive vision to treat them.With the development of technology, someday the scientist will tell us whether genetically modified food is angle or a devil.
