提到水,大概没有谁会说他对水不了解,不熟悉,不知道。我们每天都要与水打交道:我们喝水,用水冲饮料、冲茶,做饭,家居卫生及个人卫生都需要用水。水在方方面面与人们的日常生活密不可分, 可见水对于人是多么的重要。既然水与人类的关系如此密切,人们对水的了解又有多少呢? 医学实验证明:人体的70%是水,血液、其他体液绝大部分是水, 我们的心脏、肾脏,我们的脑,我们的肌肉,甚至我们的牙齿、骨骼中都含有相当比例的水。如果不喝水,人只能活几天;而喝水,不吃饭,人却能存活几十天。而且,人类的许多疾病也都是和水有关的。 Mentioned water, probably no one would say he did not understand the water, are not familiar with, do not know. We deal with the water every day: we need water to drink water, drink beverages, brew tea, cook, home hygiene and personal hygiene. Water is inseparable from people’s daily life in all aspects, showing how important water is to people. Since the relationship between water and mankind is so close, how much understanding do people have about water? Medical experiments show that 70% of the human body is water, blood and most other body fluids are water. Our heart, kidney, our brain, Our muscles, and even our teeth and bones, contain a fair amount of water. If you do not drink water, people can only live a few days; and drink water, do not eat, but people can survive for dozens of days. Moreover, many human diseases are also water-related.
