阅读理解 Consider the following three facts from a research about 1,292 kindergartens, elementary schools, middle schools and high schools. 78% of the schools have at least one fastfood place within less than a half mile or about a 10minute walk. Half the area's schools have a fastfood restaurant a third of a mile or closer, about a fiveminute walk. In some cases, the restaurant is right next door or across the street. There are three to four times as many fastfood restaurants within less than a mile of schools than they would be expected. Most public and private schools in Chicago are only a fiveto10minute walk from at least one fastfood restaurant. The city is facing the same problem like other areas. Children and teens are surrounded by unhealthy options. Students can pick up fast foods, including hamburgers, French fries, fried chicken and doughnuts, on the way to and from school. Some high school students can go off campus at lunchtime to eat it. 'Five days a week we send children to an environment where there's an abundance of highcalorie, lownutritionalquality, inexpensive food,' says Bryn Austin. The research comes from growing concerns that American schoolchildren are gaining weight. About 31% of kids aged 6 to 19 are overweight or at risk of becoming so. On days when kids eat fast food, they have more calories, more fat, more sugar and fewer fruits and vegetables than on other days. Kelly Brownell from Yale University said, 'Just like there are drugfree zones around schools, there should be zones around schools that are free of junk food, including fastfood restaurants, minimarkets and gas stations that sell food inside.' 1.
