Water and the survival of humankind and social development are closely related. Water is the water of life is an important part of life, the lives of people without water will perish.

　　Along with the development of industrialization, uncontrolled large wastewater residue into rivers, lakes, sea and the Earth's freshwater resources diminishing. Many rivers are contaminated, because pollution tens of thousands of dead fish found floating in the river surface. Drink this water is very dangerous. Water shortages, each of us are facing a serious crisis of survival.

　　Therefore, mankind must cherish freshwater resources. (生命之水)

　　Water is very important today .It is used for drinking.The plants and the animals need water,too.Also water is used for washing at home.We can’t live without water.There is only a little water in the world ,and some of it has been polluted by people.The polluted water is bad for the plants .and it will not be able to be drunk by people or animals .It is important to make good use of water.We should not be allowed to waste it and we must try our best to save water at once (水是生命)Water is life

　　Water, is a human Shengmingzhiquan, the Earth is the source of life, all life in the universe is indispensable to a substance.

　　1 do not know how the knowledge on water, too much can not keep up with culture. Water should be valuable knowledge of every person on earth to know, I do not know the water is not knowledge of the fate also. Because of drinking unsafe water or contaminated water will be life-threatening, so we should be the first time to understand water knowledge. If you do not see the naked eye drinking water is good or bad, I suggest that you use the pH value of test-card. First of all, to one of a paper placed in water, the Baptist two minutes, you will find in the water the color changes, it is the paper work, according to the colour of water to control the pH value color cards, will be able to know that water is acidic, Is alkaline, or a weak alkaline. On, the water is usually good in terms of pH greater than 7.0 was weakly basic, general and bad water pH value of less than 7.0 acid.

　　We would also like to have better water conservation, but not too much in savings, not to just 10 million metres of water used Xiwan wash your face, just Xiwan feet of water pouring out dishes. Healthy water should be reasonable and rational use of every drop of water is the real water conservation.

　　You have before them a bottle of drinking water, if you want to drink plenty of water is, you have stepped forward to see signs have QS, has rich natural balance of minerals, posted on the bottle, what is the pH value, water From where. These are checked, you can made a Tongyin.

　　Why do we drink? Weak alkaline water, it is because we need it the body's blood, if drinking acidic water will result in acidification, acidification is the source of diseases, acidification, the disease will be walked to you! Therefore, we must drink weak alkaline water, as we will be a long and healthy life.

　　We are now usually drink the water are purified water, the general water, and water was acidic, we should drink more water and some drinking natural mineral water, which are rich in various natural mineral water, suitable for our long-term Drinking.

　　Well, wrote such a long time, I also tired, Shengelanyao to, and wrote here on the. Finally, I hope that we can better understanding of water, so as to more healthy, happy life of learning.
