  有这么一句经典的话来描述放屁,“响屁不臭,臭屁不响。”这句话真的是一语中的啊,那么屁是怎么产生的呢?
  屁的产生,是因为我们吃的食物,有些未被分解。未被分解的部分,包含纤维和糖类,就成为大肠菌的食物。大肠菌饱餐后就会排气,这些气体在体内累积,造成一股气压。当压力太大时,就会了屁。这种气体排出体外之后对环境会产生一定的污染,人体虽然吸入之后虽然身体健康不会受到影响,但是会给人体嗅觉带来不雅影响,因为人为什么会放屁?不要以为这个话题恶心,因为肠子总是在不断地蠕动着。其实,只要肠蠕动存在,就会有气体从肛门排出,就会放屁。我今天所要论述的并不是生物学方面的知识。我主要是通过社会人文科学角度来阐述。自古以来,放屁这一生理想象从未因生物进化而消失,每个人都有屁要放,其实这道理跟人一样,每个人都是社会中的自然人,每个人都有思想,会思考,每个人面对世间万物都有自己的话要说,都有自己的想法和建议。每个人都有放屁的权力,这是法律赋予的公民自由权,诚然,人都有表达自我情感,表达自己内心想法的权力。但是有的人把自己的屁当作话放了出来,最后闹出了笑话,他的话不但没有很好的表达他的初衷,相反变成了屁话,此可谓弄巧成拙,贻笑大方啊。
