Probably over half of Americans are over...

Probably over half of Americans are overweight in different degrees, a fact most newcomers quickly notice. This is because of a diet that is high in fat, sugar, and salt. In the South, much food is fried or flavored with fat.

You will see many television commercials about dieting and exercising, indicating the serious concern people have about their weight problems. Many Americans lose weight by restricted diets and much exercise as obesity is considered harmful to good health, appearance, and longevity(长寿).

Many Americans can afford to eat well and have jobs that do not offer much opportunity for exercise. The possession of cars also limits the amount of exercise most people get. It is therefore easy for Americans to put on weight, and many newcomers have found that the good food and lack of exercise can add pounds on them, too.

Generally, Americans hate being overweight, and some people—especially women and teenage girls—suffer from eating disorders. These disorders can become health-threatening or ever life-threatening and often require psychiatric treatment(精神病治疗). Even those who do not suffer from eating disorders often eat carefully to control their weight.

1.According to the passage, newcomers usually ______ because of the diet and lifestyle of America.

A. get used to it    B. put on weight    C. get unhappy    D. afford to eat well

2.The best title of the passage is ______.

A. Americans Eating Disorders    B. Americans Health Problem

C. Harmful Diet in America    D. Overweight Problem in America

3.Why is it easy for Americans to put on weight?

A. Because they eat well and lack exercise.    B. Because they have good jobs.

C. Because they drive cars very often.    D. Because they suffer from eating disorders.

 

1. B 2. D 3. A 【解析】 这是一篇说明文,主要讲了美国人的超重问题。这是因为饮食中富含脂肪,糖和盐,而且缺乏运动。现在很多人开始通过限制饮食和大量运动进行减肥。 1.细节理解题。根据第三段的最后一句It is therefore easy for Americans to put on weight, and many newcomers have found that the good food and lack of exercise can add pounds on them, too。可知,一些新到美国的人也会因为美国的饮食以及缺乏运动等生活方式而变胖。故选B。 2.标题判断题。文章的首句Probably over half of Americans are overweight in different degrees, a fact most newcomers quickly notice.就点明了主题,即大约一半多的美国人都有不同程度的超重问题,因此D选项最符合文章大意,故选D。 3.细节理解题。根据第三段中的Many Americans can afford to eat well and have jobs that do not offer much opportunity for exercise.可知,很多美国人饮食较好而且没有机会锻炼,这是引起他们肥胖的主要原因,故选A。
