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 friendsaside from time in school or time spent doing homeworkwere classified as sedentary.The researchers found only one quarter of the boys and 15 percent of the girls were getting enough exercise by these definitions. A quarter of boys and nearly 30 percent of girls were sedentary and didnt get enough exercise with girls less active than boys in every country aside from Zambia.Uruguay had the highest percentage of active boys, at 42 percent, while Zambia had the lowest, at 8 percent. Girls from India were the most active, with 37 percent meeting exercise recommendation, while girls from Egypt were the least active, with just 4 percent getting adequate exercise. Children in Myanmar were the least sedentary, with 13 percent of boys and 8 percent of girls classified as sedentary. The most sedentary nations were St. Lucia and the Cayman Islands, with 58 percent of boys and 64 percent of girls spending at least three hours a day in sedentary activities.People show deep concern for kids lack of physical activity in various nations. Why do they have a low level of physical activity? Guthold speculated(推测)that urbanization(都市化) could be a factor as well as access to cars and TVs.16If you are sedentary, you_Aare a diligent student spending much time doing homeworkBhave at least an hour of exercise outdoors every dayClike watching TV and playing computer gamesDspend a lot of time sitting down and not moving17Which statement is TRUE about the finding of the study, led by Regina Guthold?AMost children around the world dont meet the exercise recommendation.BGirls in every
