Many facts suggest that children are overweight. I feel there are a number of reasons for this.
Some people blame(责备) the fact that we are surrounded by shops selling unhealthy, fatty foods. This has turned out a whole generation(一代人) of grown-ups who don’t often cook a meal for themselves. If there were fewer of these restaurants, then probably children would buy less junk 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 probably choose sweet and salty foods every time, and this will carry on throughout their lives.
There is a third reason. Children take little exercise. They do not walk to school. When they get home, they sit in front of the television or their computers. Not only is this an unhealthy pastime(消遣), it also gives them time to eat more unhealthy food. What they need is to do exercise. 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.
