I feel there are a number of reasons for this.Some people blame the fact that we are surrounded (包围) 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 will buy less takeaway food.There is another argument that blames parents for a llowing 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 a pastime(消遣), it also give 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, and steer them away from fast food shops and bad eating habits.63. According to the passage, what kind of children may eat more unhealthy food?A. Those who often took exercise.B. Those who often watch TV.C. Those who often have meals at home.D. Those who often walk to school.64. The author thinks that children are becoming overweight because _____.A. their parents often cook meals for them.B. they are too busy to go out and play.C. they can’t choose what to eat.D. there are so many fast food shops around.65. The main purpose of the passage is to _____.A. tell a story about an overweight boyB. provide facts to show different reasonsC. express the writer’s strong emotion.D. show different opinions第二节（共5小题；每小题2分，满分10分）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。
