梁同學

本場**位選手梁皓洋同學先用全球KFC的數量說明垃圾食品的龐大市場，接著解釋垃圾食品的概念，再闡述由于生活繁忙、時間變少而導致垃圾食品讓人容易上癮的現象。最后，他向聽眾呼吁——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

邱同學

第二位選手是邱君毅同學，在他看來，垃圾食品之所以如此流行，主要有三個因素：一、價格便宜優勢，與普通餐廳相比，快餐的價格相對低廉;二、從眾心理，人類在特定的環境下會不自覺地跟風，盲目從眾;三、精準的推銷方式 ，很多垃圾食品的推銷能準確地抓住消費者心理，快速搶占消費市場。

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......

姚同學

第三位選手姚博瑞同學提及垃圾食品很受歡迎，一方面是因為它有很多添加劑;另一方面，優質的廣告也成功地吸引了消費者的味蕾。此外，他還認為當代年輕人都有強烈的反叛精神，越是家長不讓做的事情年輕人就一定要去嘗試一下，這也是促進快餐受歡迎的間接原因之一。

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.

侯同學

第四位選手侯欣苒同學認為很多人明明知道快餐不健康，但偏偏還想吃的原因有三點。**，這是人類進化的結果，我們的基因偏愛高糖高熱量的食物;第二，垃圾食品可以使我們緩解壓力;第三，人們會對垃圾食品上癮。當我們吃這些高糖高熱量食物時，大腦分泌的多巴胺能使我們感到興奮和愉悅。但長期吃垃圾食品會導致肥胖，甚至內分泌失調，因而盡量少吃垃圾食品。

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.

戴同學

第五位選手戴嘉芮同學認為垃圾食品已經成了我們生活中必不可少的一部分，糖分所分泌的多巴胺讓我們的荷爾蒙上升從而感到異常愉悅。同時，她也提到了方便面和烤腸這兩個垃圾食品界的鼻祖，加深了我們對垃圾食品的影響。最后從商家角度說明，商人的營銷策略大大加深了我們對垃圾食品的依賴程度。

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.

楊同學

第六位選手楊智恒同學圍繞著‘為什么垃圾食品如此流行’這個話題展開分析，他提出了使消費者選擇垃圾食品的三個重要方面：便宜，方便和美味，并依次舉例分析，有理有據，將消費者沉迷于垃圾食品的真相層層揭開。

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.

縱觀本期六位同學的演講，大家一致呼吁要盡量遠離垃圾食品，**健康環保生活。伴隨著同學們熱烈的掌聲，經過激烈的角逐，本場排名**的是戴嘉芮同學，希望同學們再接再厲，在演講臺上展現智慧和邏輯碰撞出的耀眼火花。
