Les niveaux de connaissance en langue ont été classés et définis par le Conseil de l'Europe. Cette norme européenne, appelée cadre européen commun de référence, est acceptée et reconnue dans tous les pays de l'Union Européenne. Elle détermine précisément les compétences que doit posséder l'apprenant pour communiquer dans certains contextes.
An American scientist, David Allison from New York has developed a television which only works if you pedal a bicycle. Allison is a researcher into weight problems at St Luke's Roosevelt Hospital in New York. It is estimated that more than 16% of American children between 6 and 17 are overweight. Lack of exercise is thought to be the main cause. Children are becoming "couch potatoes" and spend on average 20 hours a week watching TV.
He tested the bike on a group of children between the ages of 8 and 12. At the end of the experiment, the children had all lost weight. They were also spending less time in front of the television!
Allison believes that exercise rather than dieting is the key to children's weight problems and that it is essential to get them moving.
