61.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 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.

Many universities are providing more financial (财政上的) aid for their students. 62.If there were few 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, because good eating habits begin early in life, long before children start to visit fast food shops.

There is a third reason for this situation. Children these days take very little exercise. They do not walk to school. 63. 他们一回家就是坐在电视机前或电脑前玩电脑游戏。64. Not only is this an unhealthy pastime(消遣)， it also gives them time to eat more unhealthy food. 65.他们所需要的是走出去并进行运动。 The above are the main reasons for this problem, and therefore we have to encourage young people to be more active, as well as steering them away from fast food shops and bad eating habits.
