填空题We eat at the fast food restaurants more because it is quick than because we really need the food.____

第1题：

In the United States, 30 percent of the adult population has a "weight problem". To many people, the cause is obvious: we eat too much. But scientific evidence does little to support this idea. Going back to the America of 1910, we find that people were leaner than today, yet they ate more food. In those days people worked harder physically, walked more, used machines much less, and didn't watch TV.

Several modern studies, moreover, have shown that fatter people do not eat more on average than thinner people. In fact, some investigations, such as a 1979 study of 3, 545 London office workers, report that, on balance, fat people eat less than slimmer people.

Studies show that slim people are more active than fat people. A study by a research group at Stanford University found the following interesting fact:

The more the man ran, the greater loss of body fat.

The more they ran, the greater their increase in food intake.

Thus, those who ran the most ate the most, yet lost the greatest amount of body fat.

1、What kind of physical problem do many adult Americans have?____

A、They are too slim.

B、They work too hard.

C、They are too fat.

D、 They lost too much body fat.

2、Based upon the statistics given in the article, suppose there are 500 adult Americans, about how many of them will have a "weight problem"?____

A、 30.

B、 50.

C、100.

D、150.

3、Is there scientific evidence to support that eating too much is the cause of a "weight problem"?____

A、Yes, there is plenty of evidence.

B、Of course, there is some evidence to show this is true.

C、There is hardly any scientific evidence to support this.

D、We don't know because the information is not given

4、In comparison with the adult American population today, the Americans of ____.

A、ate more food and had more physical activities

B、ate less food but had more activities

C、 ate less food and had less physical exercise

D、had more weight problems

5、What have modern medical and scientific researches reported to us?____

A、Fat people eat less food and are less active.

B、 Fat people eat more food than slim people and are more active.

C、 Fat people eat more food than slim people but are less active.

D、 Thin people run less, but have greater increase in food intake.

第4题：

The food we eat seems to have profound effects on our health.Although science has made enormous steps in making food more fit to eat ,it has, at the same time,made many foods unfit to eat. Some research has shown that perhaps eighty percent of all human illnesses are related to diet and forty percent of cancer is related to the diet as well,especially cancer of the colon. Different cultures are more likely to cause certain different illnesses because of the food that is characteristic in these cultures. That food is related to illness is nto a new discovery. In 1945, about 35 years ago, government researchers realized that nitrates, commonly used to preserve color in meats,and other food additives,caused cancer. Yet, these carcinogenic additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to beef and living animals, and because of this ,penicillin has been found in the milk of treated cow. Sometimes similar drugs are given to animals not for medical purposes,but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration(FDA) has tried repeatedly to control these procedures, the practices continue.
Which of the following statements is NOT ture?

a.Drugs are always given to animals for medical reasons
b.Some of the additives in our food are added to the food itself and some are given to the living animals
c.Researchers have known about the potential dangers of food additives for over thirty-five years.

问答题

Practice 1　　When it comes to food, America is not just the fattest country on earth but probably the most schizophrenic as well—home to the Big Mac and Weight Watchers, the super model and the couch potato.　　The love-hate relationship with food was examined in the aired documentary “Fat”, and if there is any comfort for the more than 90 million overweight Americans it’s that the rest of the world is also getting fatter.　　“There is an enormous pressure on people to be thin and to be physically fit but at the same time there is a tremendous pressure and inducement to eat,” Dr. Kelly Brownell, professor of psychology at Yale University and a participant in the program, said in an interview.　　“You’ll see a Baskin Robbins next to Weight Watchers. You’ll see a Family Circle magazine with a delicious chocolate on the cover beside a diet article,” said Brownell. “At the same time as we have record levels of obesity, we have record levels of eating disorders6 too,” he said.　　The desire to eat fatty food came from a primitive survival instinct to store enough energy in good times to ensure survival when food was scarce. But in a modem urban society, where fast food chains appear on almost every block, the instinct to eat fat has begun to work against us.　　The documentary claims that nowhere is the exposure to junk food more prevalent than in the United States, where the problem has been compounded by the increasingly sedentary modem lifestyle.　　It also says that members of Arizona’s Pima Indian tribe are the fattest people in the fattest country on earth. Until recently the tribe lived a simple life, but in 1984 when the tribe won a gaming license it joined the American mainstream. Today the tribe is plagued by obesity, diabetes, high blood pressure, and heart disease.　　Just 800 kms south in Mexico, another branch of the Pima tribe continues to live a traditional life and eats a traditional diet. These Pimas have none of the problems of their American counterparts, who are on average 27 kgs heavier.　　Part of the problem, according to Brownell, is the intense advertising of junk food in the United States. The average American child sees thousands of TV commercials each year, most of which advertise fast food, candy and soda.　　The food environment has become so “toxic” according to the documentary, that some US　schools even offer fast food such as McDonald’s and Burger King in school cafeterias.　　But junk food is also proliferating overseas, resulting in increasing rates of obesity in such　countries as China, where fast food restaurants have recently taken hold.　　Compounding the new-found availability of junk food is the changing opinion on what is the ideal body. These days thin are king.

正确答案：参考译文
谈及饮食,美国不仅是世界上最肥胖的国家,也可能是对食物持最自相矛盾态度的国家—这里,既有援贫济困的大麦克公司,又有每日心挂体重的减肥者,既有超级名模,又有终日泡在电视机前不思运动的人。
专题片《肥胖》调查了人们对食物爱恨掺杂之情。如果对于九千多万美国肥胖者来说有什么值得欣慰的,那便是,世界上其他国家的人也胖了很多。
“对于人们来说想要瘦身并保持身体健康可是一个不小的压力,并且,人们在吃饭时既要承受极度压力,又忍不住巨大诱惑,”耶鲁大学的心理学教授凯利·布朗内尔在专题节目中接受采访时说道。
“你能看到在减肥者身边有关国贝罗公司生产的31种风味冰淇淋,你也可以看到《家庭圈》杂志封面上精美的巧克力蛋糕和瘦身食品印在一起,”布朗内尔说。“同时,我们有创纪录的过度肥胖,也有创纪录的过度节食,”他说。
多吃含脂肪食物的欲望来源于原始人类的求生本能——在食物充沛的时候储存充足能量以备食物不足时渡过难关。但是在现代都市社会里,快餐连锁店遍布每一条大街,喜欢吃含脂肪食物的本能对我们不利起来。
《肥胖》专题片认为,世界上没有哪个国家像美国那样垃圾食品随处可见、风靡时兴,而且让这一态势更糟糕的是,伏案工作的现代生活方式越来越盛。
专题片中也提到,亚利桑那州皮马部落的印第安人是当今最肥胖的国度里最肥胖的人。直到最近,皮马人都过着简单的生活,不过当l984年他们获得了博彩业特许证,便加入了主流的美国生活。如今该部落深为过度肥胖、糖尿病、高血压和心脏病所困扰。
在墨西哥以南不过800公里居住着另外一支皮马部落,他们仍然过着传统的生活,保持传统的食物结构,与平均体重超过他们27公斤的美国皮马人相比,他们没有得上上面提到的任何一种疾病。
在布朗内尔看来,部分症结在于美国广告大肆宣传垃圾食品。美国孩子平均每年要看几千个电视广告,其中大部分是快餐、糖果和汽水。
根据《肥胖》专题片的调查,美国食物的环境已经变得非常“有害”,有些学校甚至在食堂里供应麦当劳和汉堡王之类的快餐。
但是垃圾食品在海外也迅速风靡起来,结果是在诸如中国之类的国家里过度肥胖者增加。近几年来这些国家的快餐店已经风行起来。
人们新近发现,垃圾食品随处可见;然而使得这一境况更为复杂的,是人们对理想身材的看法又改变了。现在人们认为瘦就是好。

◆Topic 12：Fast Food　　Questions for reference:　　1) Fast food is a good reflection of the quick-paced modern society. What role does fast food play in China?　　2) Why is fast food so popular? What are the demerits of fast food?　　3) What attitude should we have towards fast food?

正确答案：【参考答案】
Fast food is becoming more popular in China, especially among children and teenagers. Today, it’s certainly difficult to think of any other single thing that represents the fast pace of modern society as powerfully as fast food.
There are several reasons for its popularity. First, it is very convenient and saves a lot of time. The trends of modern society seem to all point to one ultimate goal-saving time, and fast food well serves this purpose. You just go into a fast food restaurant, order your food, and your food is ready in no time. You can either eat it there or take it away. Second, its popularity is also attributed to the clean and comfortable environment of fast food restaurants, the excellent service, and the guaranteed quality of food.
However, in terms of nutrition, fast food is far from satisfactory. It usually does not compose a balanced diet and is low in nutritional value. Thus, doctors suggest that people, especially children, eat fast food as little as possible. Although cooking at home is time-consuming and the following washing-up tiresome, it offers healthy and delicious meals your body likes and needs. Fast food is only a good choice when you are in a hurry and turn to it once in a while.

Different cultures are more likely to cause certain different illnesses because of the food that is characteristic in these cultures. That food is related to illness is nto a new discovery. In 1945, about 35 years ago, government researchers realized that nitrates, commonly used to preserve color in meats,and other food additives,caused cancer. Yet, these carcinogenic additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to beef and living animals, and because of this ,penicillin has been found in the milk of treated cow. Sometimes similar drugs are given to animals not for medical purposes,but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration(FDA) has tried repeatedly to control these procedures, the practices continue. What are nitrates used for?（）

A

They preserve flavor in packaged foods.

B

They preserve the color of meats.

C

They are the objects of research.

D

They cause the animals to become fatter.
