2. There is a definite trend towards a more sustainable way of eating rather than fad diets. 有一种明确的趋势，朝向更能持续的饮食方式，而非一时流行的饮食。
3. When your son lets his hair grow to his shoulders, or your daughter experiments with white makeup, accept the appearance as a harmless fad. 当你的儿子要把头发蓄到肩膀或是你的女儿要尝试增白化妆品时，权且把这种装扮当作无害的时髦。
