问题    Obesity is the single greatest cause of early deaths after smoking. It results in more years of unhealthy life, diminishing the quality of life. It also increases many physical and mental health issues, from heart disease to diabetes (糖尿病) to cancer and depression.
   Recently, childhood obesity has become the greatest cause for concern. For children in year six obesity rates have increased at a significant pace—around 5% a year for the past decade—so that now one in three children are obese by the time they leave primary school. The rate of childhood mental illness is accelerating and is both a cause and a symptom of the obesity crisis.
   Obesity is one of the most complex public health challenges that we face. It does not have a single cause. The reasons for it are wide-ranging. But above all, it is a social challenge. It is about education and social norms for eating and exercise. It is about how food companies formulate their products, how they are labelled and advertised, and how they are priced and displayed in shops. Work and school play a crucial role: more and more jobs are sedentary (久坐的) and kids are less and less likely to expend energy playing outdoors. The quality of our public spaces and transport systems makes an important difference too.
   We argue for fresh thinking to challenge the assumption that issues like obesity are a " disease of the will" and to encourage more support for people to make healthier choices. Local authorities should be given new powers to stop fast-food outlets opening near schools, to prevent them from selling high-calorie products to schoolchildren, and to ban junk food advertising near the school gates.
   We must remember that unhealthy behaviour today is costly tomorrow. Now is the time for more action and more investment—the quality and length of our children’s lives depend on it.
According to the author, what should the government do to control childhood obesity?
选项 A、Develop the public transportation.
B、Ban the selling of unhealthy foods around schools.
C、Give more power to schools.
D、Prevent the opening of fast-food stores.
答案B
解析 事实细节题。由定位句可知，地方当局，即地方政府应阻止在学校附近开设快餐店，防止他们向小学生销售高热量食品，故答案为B)。A)“发展公共交通”，第三段最后一句提到交通系统的质量与肥胖有关，但并未指出政府应发展公共交通，故排除该项；C)“赋予学校更多权力”，文中并没有提到赋予学校更多权力，而是赋予地方当局新的权力，故排除；D)“阻止开设快餐店”，定位句指出地方当局应阻止在学校附近开设快餐店，并未指出阻止开设所有快餐店，故排除。
