Question

There are a lot of people who are overweight all over the world. What causes obesity? If you get the gene(基因), well, probably you are going to be a few more pounds heavier compared to the rest of your classmates or friends. 1. Obesity can not only make a person look heavy, and not in the usual sense of being handsome, but can also lead to serious health conditions and life-threatening diseases.

2. Indeed, junk food has been blamed for the prevalence(流行）of obesity. It is called junk food, because hamburger, pizza and the like contain high calories. If you eat a Big Mac (a super hamburger), an order of large fries, and a large Coke, you will need to walk non-stop for six hours to burn off the calories you have gained. And don’t be fooled by soft drinks, which are high in sugar and are a major cause of obesity.

3. Popular sugary drinks, of course, include Coca Cola, Pepsi(百事) Cola, and many new brands that appear on the market every couple of days.

4. Just one 20-ounce (about 567g) bottle of soda can have 250 calories, which are equal to more than 16 teaspoons of added sugars. Even a lemon-flavored iced tea can have 210 calories.

5. Next time, when you are ready to eat that huge Mac and to drink that two-liter bottle of Pepsi, probably it’s a good idea to give it a second thought.

A. Obesity is more common in women than men.

B. Most people don’t realize how easy it is to gain weight from drink sugar-sweetened beverages(饮料)

C. When we talk about obesity, the first thought that comes to mind is: junk food.

D. The unburnt calories will put weight on you.

E. Keeping healthy is our own responsibility.

F. Because of their high content of sugar, soft drinks are also called sugary drinks.

【解析】本文主要介绍了肥胖产生的原因，最主要的原因是垃圾食品，比如巨无霸汉堡包、披萨、可乐等含糖饮料，它们含有高热量，容易导致肥胖。呼吁大家保持健康是我们自己的责任，要学会自律，健康饮食。

1.文章第一段 What causes obesity? 说明是在揭示引起肥胖的原因。选项中揭示原因的有G. However, the most common cause of obesity is eating too much, especially too much junk food.然而，肥胖最常见的原因是吃得太多，尤其是过多的垃圾食品。根据下文垃圾食品导致了肥胖症的流行，说明垃圾食品是导致肥胖的重要原因。故选G

2.根据第二段Indeed, junk food has been blamed for the prevalence(流行）of obesity.可知本段在说明垃圾食品是导致废品堆原因，C. When we talk about obesity, the first thought that comes to mind is: junk food.当我们谈论肥胖时，首先想到的是：垃圾食品。后面的Indeed也与C项内容相呼应，故选C。

3.第三段大意为:流行的含糖饮料，当然，包括可口可乐，百事可乐（百事），和许多新的品牌每隔几天出现在市场。提到了含糖饮料，只有B. Most people don’t realize how easy it is to gain weight from drink sugar-sweetened beverages(饮料)大部分人没有意识到它是多么容易从喝含糖饮料增加体重F. Because of their high content of sugar, soft drinks are also called sugary drinks.由于含糖量高，软饮料也叫含糖饮料。本段并没有说喝含糖饮料会增加体重，故排除B选择F。

4.第四段大意为只是一个约567g的汽水可以有250卡路里的热量，这相当于超过16茶匙的糖。即使是柠檬口味的冰茶也有210卡路里的热量。这说明含糖饮料热量很高容易导致肥胖，B. Most people don’t realize how easy it is to gain weight from drink sugar-sweetened beverages(饮料)大部分人没有意识到它是多么容易从喝含糖饮料增加体重。正好与本段内容相符，故选B。

5.段落大意为：下次，当你准备吃那巨大的汉堡包和喝两公升百事可乐时，可能思考两秒是个好办法。说明要进行自律。与E. Keeping healthy is our own responsibility.

保持健康是我们自己的责任。相符合，故选E。

【名师点睛】

注意一些特殊疑问词。如果选项中或空前出现特殊疑问词，一定要把这句话仔细读几遍，因为对于不同特殊疑问词的回答方式是不一样的，比如对why的回答，后面要有because等表原因的词，对when的回答，后面要有表时间的状语，对where的回答，后面要有表地点的名词，对how的回答，后面要有方式状语等。

比如第1小题，文章第一段 进行提问What causes obesity? 选项中揭示原因的有G. However, the most common cause of obesity is eating too much, especially too much junk food. 然而，肥胖最常见的原因是吃得太多，尤其是过多的垃圾食品。在根据下文内容进行推测，故选G。
