你知道吗?每吸一支烟,能使我们周围PM2.5的浓度增加数十倍。2012年5月31日,是第二十五个世界无烟日。今年的口号是“生命与烟草的对抗”。为提高全校师生及家长的公德意识和文明素质、加强对吸烟危害性的宣传,新疆兵团二中小学少先大队部和科学组组织了以“绿色无烟清新自然”为主题的系列活动。同学们在体验中获得知识,用小手拉起大手,以实际行动共同营造清新环境。 Did you know that each inhalation of a cigarette can increase the concentration of PM2.5 around us by tens of times? May 31, 2012 is the twenty-fifth World No Tobacco Day. This year’s slogan is “Confrontation between life and tobacco.” In order to improve the public awareness of teachers and parents and the quality of civilization of teachers and parents, and to intensify the publicity on the dangers of smoking, the less-advanced brigades and ministries of Xinjiang Primary and Secondary Schools organized the series entitled “Green and Smoke-free Fresh and Natural” activity. Students gain knowledge in the experience, pull big hands with small hands, and work together to create a fresh environment.
