梁同学

本场**位选手梁皓洋同学先用全球KFC的数量说明垃圾食品的庞大市场，接着解释垃圾食品的概念，再阐述由于生活繁忙、时间变少而导致垃圾食品让人容易上瘾的现象。最后，他向听众呼吁——多多食用健康的食品。

Another very important reason for the popularity is that they can cause you addicted to them. The Scripps Research Institute in US found that experimental rats often ate sausages, bacon, and other high-calorie food, and then the brain underwent some changes. These changes are similar to the changes that appear when animals are addicted to cocaine, heroin and other drugs.

More and more people are starting to favor vegetarian diets; if it is possible, they would rather choose low-sugar and low-fat foods; or just eat fruits for a week in order to lose weight. Not because they don't like to eat those junk foods, but because they are afraid of the result.2

邱同学

第二位选手是邱君毅同学，在他看来，垃圾食品之所以如此流行，主要有三个因素：一、价格便宜优势，与普通餐厅相比，快餐的价格相对低廉;二、从众心理，人类在特定的环境下会不自觉地跟风，盲目从众;三、精准的推销方式 ，很多垃圾食品的推销能准确地抓住消费者心理，快速抢占消费市场。

What is junk food? First, let's back up and define "junk foods." It's the stuff you eat that has little or no nutritional value, usually combined with ingredients that are bad for you, or is high in calories when consumed in excess. So many things are junk food.Such as : chips , cake, candy......

姚同学

第三位选手姚博瑞同学提及垃圾食品很受欢迎，一方面是因为它有很多添加剂;另一方面，优质的广告也成功地吸引了消费者的味蕾。此外，他还认为当代年轻人都有强烈的反叛精神，越是家长不让做的事情年轻人就一定要去尝试一下，这也是促进快餐受欢迎的间接原因之一。

There is another reason, have you ever seen the advertisement in which some people are eating the fried chickens or something else and tear them in purpose? Does that make you hungrier and want to have one? The answer is obvious, right? So, I really hate this but you cannot deny that they have succeeded in attracting your attention and arousing your desire.

侯同学

第四位选手侯欣苒同学认为很多人明明知道快餐不健康，但偏偏还想吃的原因有三点。**，这是人类进化的结果，我们的基因偏爱高糖高热量的食物;第二，垃圾食品可以使我们缓解压力;第三，人们会对垃圾食品上瘾。当我们吃这些高糖高热量食物时，大脑分泌的多巴胺能使我们感到兴奋和愉悦。但长期吃垃圾食品会导致肥胖，甚至内分泌失调，因而尽量少吃垃圾食品。

Third, people can be addicted to junk food.Junk food, which has almost no nutrients, causes your brain to produce a substance called dopamine. Dopamine is a neurotransmitter, a chemical that helps cells deliver impulse. This kind of brain endocrine is mainly responsible for sexual desire, feeling, excitement and happy information transmission of the brain. Like love ... love is also a result of a flood of dopamine in the brain. So love, like eating junk food, makes you happy and excited.

戴同学

第五位选手戴嘉芮同学认为垃圾食品已经成了我们生活中必不可少的一部分，糖分所分泌的多巴胺让我们的荷尔蒙上升从而感到异常愉悦。同时，她也提到了方便面和烤肠这两个垃圾食品界的鼻祖，加深了我们对垃圾食品的影响。最后从商家角度说明，商人的营销策略大大加深了我们对垃圾食品的依赖程度。

Taking McDonald’s as an example,the large pictures that the sellers use on advertisements or menus are much more attractive than real food so that it will catch our eyes instantly. But the price of this food is not marked next to the picture or the price only take very small part of the picture. This strategy greatly reduces our consideration on price and increases our desire for food. As a result, desires take controls and all we want is to satisfy ourselves.

杨同学

第六位选手杨智恒同学围绕着‘为什么垃圾食品如此流行’这个话题展开分析，他提出了使消费者选择垃圾食品的三个重要方面：便宜，方便和美味，并依次举例分析，有理有据，将消费者沉迷于垃圾食品的真相层层揭开。

Thousands of years ago, human was looking for high calorie’s food like sweet fruits or fatty meat. Those foods can provide more energy which can increase people's survival rate at that time. Even in the modern age people can get food easily, but our brain is still the reply same desire. And this is the reason why junk food is so popular.

纵观本期六位同学的演讲，大家一致呼吁要尽量远离垃圾食品，**健康环保生活。伴随着同学们热烈的掌声，经过激烈的角逐，本场排名**的是戴嘉芮同学，希望同学们再接再厉，在演讲台上展现智慧和逻辑碰撞出的耀眼火花。
