今天,我和小伙伴们一起去玩耍。一出门，一股难闻的汽油味扑鼻而来。我们立刻跑了回去，开了一个关于空气的讨论会。

我说：“据新闻介绍：有些人能活到九十几岁、甚至一百多岁!你们知道这是为什么吗?”

“为什么?”他们好奇的问。

我说：“因为那些人都住在深山或乡村里……而那里的空气特别新鲜，没有什么污染。可为什么我们这里的空气没有那些深山或乡村里的那么新鲜呢?”

郑鑫说到：“因为我们这儿随着社会不断的'进步、发展，工厂和机动车散发出来的气体污染了我们的空气，一些体抗力差的人吸了这些空气后，就会生病。”

“还有还有……”小小等不及了，迫不及待地说，“有些人随地乱丢塑料袋，有的人觉得垃圾箱太远，就随手乱丢，草地上、马路上……时间长了，就有一股股难闻的臭味。其他人为了省力，就把垃圾直接用火烧了，发出一股焦味，这两样也污染了新鲜空气。他们不知道，这一烧，给空气造成了多大的危害，给人们造成了多大的麻烦……”

我说：“那有什么办法保护空气呢?”

高雅说：“我们多种植些树木，让树叶的清香赶走难闻的气味，制造出新鲜空气。”

小小说：“我真想快快长大，好好学习。长大后当一名科学家，发明出一种专门制造空气的机器来.。”

我们真心希望这些愿望能早日成真，不要人们为空气而烦恼。
