阅读理解。 A new research shows that in Britain more and more people are returning to the old tradition that the whole family have a meal at table. Worrying about the obesity and breakdown of a family, people change their eating habits so greatly, according to analysis. They find the number of the family having a meal together increases by 5% from 2002 to 2004, and most people who have meals with their family come from the rich social class. The new discovery makes doctors and the people struggling against obesity extremely excited. Giving up the tradition that the whole family have a meal together is exactly one of the reasons for a series of problems including children's overweight. If a child has a meal in front of the television or the computer alone, he will often eat some fast food. Jason Collins is one of the persons returning to the old tradition. Collins is a manager of a bake (烘面包) house. He finds after he gets used to having a meal at home with his child, the child becomes much more obedient (听话的). Dr. Jin is a child psychologist, and she expresses welcome to this result of the study. She says it can make parents have a very good chance to chat with the child when the whole family have a meal together. 1.
