题目列表(包括答案和解析)
American children aren’t the only couch potatoes. According to a study of over 70,000 teens in 34 nations, nearly 1/3 of children globally spend three hours a day or more watching TV or on computers. From Argentina to Zambia, Regina Guthold of the World Health Organization in Geneva and her colleagues found most children aren’t getting enough exercise and it made no difference if they lived in a rich or a poor country. “With regard to physical activity levels, we did not find much of a difference between poor and rich countries, ” Guthold said. “ Growing up in a poor country does not necessarily mean that kids get more physical activity.” The study, published in The Journal of Pediatrics, looked at 72,845 schoolchildren aged 13 to 15 from North an South America, Asia, Europe, and the Middle East. The children were surveyed between 2003 and 2007.
The researchers defined adequate physical activity as at least an hour of exercise outside of gym class at least five days a week. Children who spent three or more hours a day watching TV, playing computer games, or chatting with friends----except from time in school or time spent doing homework---were classified as sedentary (久坐的). The researchers found only 1/4 of the boys and 15% of girls were getting enough exercise by these definitions. 1/4 of boys and approximately 30% of girls were sedentary and didn’t get enough exercise with girls less active than boys in every country except from Zambia. While the study didn’t look at the reasons behind the lack of physical activity in various nations, it is believed that urbanization(城市化) could be a factor as well as to cars and TVs.
