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

Answer 1

【小題1】D
【小題2】A
【小題3】D
【小題4】C

解析試題分析：文章關(guān)注的是兒童的健康問題。每天花3小時以上的時間看電視、玩游戲或聊天，而不運(yùn)動的生活方式被稱為“sedentary”，是“不愛運(yùn)動”的意思。全世界范圍來看，大多數(shù)孩子都缺乏身體鍛煉，人們對于這個問題表示了很深的關(guān)切。
【小題1】根據(jù)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，每天花超過3小時的時間看電視、玩游戲或聊天等屬于不愛活動的生活方式，并非“喜歡看電視、打游戲”就是不愛活動，故選D。
【小題2】根據(jù)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，從全世界范圍來看，大多數(shù)孩子都沒有達(dá)到足夠的身體鍛煉水平，故選A。
【小題3】根據(jù)倒數(shù)第二段“Children in Myanmar were the least sedentary while the most sedentary nations were St .Lucia and the Cayman Islands.”可知，緬甸的兒童最愛活動，而圣盧西亞和開曼群島群島的孩子最不愛活動，故選D。
【小題4】根據(jù)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，接下來的一段可能會分析現(xiàn)在的兒童缺乏鍛煉的原因。故選C。
