　　【参考译文】
　　我们都知道清洁空气对于健康是很重要的。无论你去哪里,无论你做什么,你总是被海洋包围的气体,我们称之为空气。如果空气中有杂质,它们可能会被我们的身体吸收,使人生病。我们需要清洁的空气,但不幸的是,空气污染是目前全球,尤其是在城市。
　　许多大城市都无污染。我们的城市有很多工厂,我们需要食物,衣服和其他东西。每年这些工厂倒成百上千万吨的烟雾进入空气。燃烧煤炭的发电厂和房屋也大大加重空气污染。除此之外,在城市有更多的汽车。一旦在街上,他们将在新鲜空气和有毒气体取代它。
　　我们的国家正努力预防和控制空气污染。只要每个公民也意识到它的重要性,使加入的努力,这一天很快就会到来,当人们将只在清洁空气。然后,阳光将不再是黑烟,烟灰。
