Question

American children are not the only couch potatoes with nearly one third of children globally spending 3 hours a day or more watching TV or on computers, according to the study of over 70,000 teens in 34 nations.

  From Argentina to Zambia, Regina Guthold of the World Health Organization in Geneva and her colleagues found most children were not getting enough exercise and that it made no difference whether they live in a rich or a poor country. “With regards to physical levels, we didn’t find much of a difference between rich and poor countries,” Guthold said, “Growing up in a poor country doesn’t necessarily mean kids get more physical activities.”

  The researchers defined adequate physical activity as at least an hour of exercise outdoors for at least 5 days a week. Children spending 3 or more hours a day watching TV, playing computer games or chatting with friends were classified as sedentary.

  The researchers found only a quarter of the boys and 15 percent of the girls were getting enough exercise by these definitions. A quarter of boys and nearly 30% of girls were sedentary and didn’t get enough exercise with girls less active than boys in every country aside from Zambia.

  Girls from India were the most active with 37 percent meeting exercise recommendation, while girls from Egypt were the least active with 4 percent getting enough exercise. Children in Myanmar were the least sedentary while the most sedentary nations were St .Lucia and the Cayman Islands.

  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（认为）that urbanization could be a factor as well as easy access to cars and TVs.

【解析】

试题分析：文章关注的是儿童的健康问题。每天花3小时以上的时间看电视、玩游戏或聊天，而不运动的生活方式被称为“sedentary”，是“不爱运动”的意思。全世界范围来看，大多数孩子都缺乏身体锻炼，人们对于这个问题表示了很深的关切。

1.根据第三段“Children spending 3 or more hours a day watching TV, playing computer games or chatting with friends were classified as sedentary.”可知，每天花超过3小时的时间看电视、玩游戏或聊天等属于不爱活动的生活方式，并非“喜欢看电视、打游戏”就是不爱活动，故选D。

2.根据第二段“her colleagues found most children were not getting enough exercise and that it made no difference whether they live in a rich or a poor country.”可知，从全世界范围来看，大多数孩子都没有达到足够的身体锻炼水平，故选A。

3.根据倒数第二段“Children in Myanmar were the least sedentary while the most sedentary nations were St .Lucia and the Cayman Islands.”可知，缅甸的儿童最爱活动，而圣卢西亚和开曼群岛群岛的孩子最不爱活动，故选D。

4.根据最后一段“People show deep concern for kids’ lack of physical activity in various nations. Why do they have a low level of physical activity?”可知，接下来的一段可能会分析现在的儿童缺乏锻炼的原因。故选C。
