自从地球上有了水,也就有了生命。水是生命不可缺少的物质之一,是人的命根子。 有一种说法,如果把大自然中的江、河、湖水称为第一代饮用水,那么经过井水、自来水、矿泉水到纯净水,现在已经是第五代了。还有一种说法,现在的欧美日等发达国家都已改用第五代饮用水了,也就是说,人家别的水不喝,就喝纯净水,透着那么先进,那么发达。 There has been life since there was water on the earth. Water is one of the essential things of life, is the lifeblood of people. There is a saying that if the rivers, rivers and lakes in nature are called the first generation of drinking water, it is now the fifth generation through well water, tap water and mineral water to pure water. There is also a saying that the developed countries such as Europe, the United States and Japan have all switched to the fifth generation of drinking water now. That is to say, if people do not drink any other water, they drink pure water and are so advanced and well-developed.
