水,生命之源。人的一切生命活动,都离不开水。水不仅是生命存在的基本条件,还是生命结构的主要元素。水在人体中所占的比重为70%。人体一旦缺水,血流不畅,血液干涸,细胞干瘪,机体就会瘫痪。人从生到死,实际上是一个脱水的过程。据公众健康饮用水研究所调查,全国有九成人喝水量不够。多数人不能像定时吃饭那样定时喝水,只在口渴时才喝,这说明目前“水盲”远比文盲要多。 Water, the source of life. All human life activities are inseparable from the water. Water is not only the basic condition for the existence of life, but also the main element of the structure of life. Water accounts for 70% of the human body. Once the body is short of water, poor blood flow, blood dry, dry cells, the body will be paralyzed. From birth to death, in fact, is a dehydration process. According to a survey conducted by the Public Health and Drinking Water Institute, 90% of the country has enough drinking water. Most people can not drink regularly as regular meals, only drink when they are thirsty, indicating that at present, “water blindness” is far more than illiterate.
