Many facts suggest that children are overweight and the situation is getting worse, according to the doctors. I feel there are a number of reasons for this.
Some people blame the fact that we are surrounded by shops selling unhealthy, fatty foods, such as fried chicken and ice cream, at low prices. This has turned out a whole generation of grown-ups who seldom cook a meal for themselves. If there were fewer of these restaurants, then probably children would buy less take-away food.
There is another argument that blames parents for allowing their children to become overweight. I agree with this, because good eating habits begin early in life, long before children start to visit fast food shops. If children are given fried chicken and chocolate rather than healthy food, or are always allowed to choose what they eat, they will go for sweet and salty foods every time, and this will carry on throughout their lives.
There is a third reason for this situation. Children these days take very little exercise. They do not walk to school. When they get home, they sit in front of the television or their computers and play computer games. Not only is this an unhealthy pastime, it also gives them time to eat more unhealthy food. What they need is to go outside and play active games or sports.
The above are the main reasons for this problem, and therefore we have to encourage young people to be more active, as well as steer them away from fast food shops and bad eating habits.

(答案→)B 解析：本文是一篇说理性议论文。作者论述了儿童肥胖的几个主要因素，比如说快餐食品，不健康的饮食习惯以及缺少锻炼等等，告诫少吃快餐，养成良好的饮食习惯，多锻炼身体。【小题1】根据第四段中When they get home, they sit in front of the television…eat more unhealthy food可知正确答案为B。【小题2】根据第二段we are surrounded by shops selling unhealthy, fatty foods【小题3】根据上下文语境，快餐是儿童超重的一个重要因素，因此此处应为引导年轻人离开快餐。steer 是“驾驶，掌舵，引导”之意。 【小题4】本文的意图是让人们引以为戒并提供给建议。故选答案C。
