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 Earths 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 cant 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 bodys 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.

5月31日是第21个世界无烟日，对环境与生命的热爱，而且向吸烟的同学发出了摒弃烟草的号召，让更多的朋友加入到无烟队伍里来，为构建无烟环境尽一分力量。作为学校生，我们应当从自身做起，珍爱自己，关爱他人，不要让我们在年华初绽的时候就让烟淹没了我们的人生。年华似水，青春绚烂，远离烟草，放飞梦想！
让我们呼唤无烟环境的到来，呼唤人类远离香烟，靠近健康每一天。回想过去，人类的一举一动都在伤害着地球母亲，人类在频繁地吸着就是频繁地伤害着人类,看到人类这样无视着地球母亲，烟看来和毒品没什么分别，偏偏知道对自己的身体没有一点好处还要不断地吸，这还不是和毒品一样吗？越吸越上瘾，这一张张画面使人真的看不下去！吸烟不仅危害着自己的生命，而且还危害大他人的生命，还危害这这个地球，可想而知香烟对我们人类的毒害是多么的大！当你忍不住要吸烟时，请三思而后行。
我非常反感吸烟，因为我知道烟不是什么好东西，我想对迷恋吸烟的人们说：香烟就是毒品，别让太多的烟模糊了自己的眼睛！我调查到：世界卫生组织(WHO)指出，压倒一切的科学证据表明，烟草的使用与日益蔓延全球的死亡和疾病流行高度相关。烟草是导致人们失能和早死的主要原因。90年代初，每年全世界就有300万人死于吸烟。在欧洲近50万人；在美国近43万人死于吸烟有关的疾病(占死亡总数的1/6)。在常吸烟者中，有1/4以上的人会发生早死〔1〕。中国近年的调查结果证明，全国每年近80万人死于与吸烟有关的疾病在中国25万人吸烟与死亡率前瞻性研究中发现，在1992～1995年间这个队列中已有8688人死于与吸烟有关的疾病，死亡率为9.9。在40岁以上的中国人群中，吸烟导致的死亡已经达到总死亡人数的12%。按照中国人群目前的吸烟水平预测，到2000年，死于吸烟的人数将为100万，到2025年为200万，到2050年为300万。如果中国人的吸烟行为不发生改变，到下一世纪，目前0～29岁的男性中将有300万人成为吸烟者，其中至少有100万人将死于吸烟，而有一半是在35～69岁这个年龄段死去的。吸烟的朋友们，你们看到这些有什么感想，有想过要戒烟吗，来和我们一起保护这个美丽的地球吗？烟的梦，叫我恐怖。吸烟的朋友们们远离香烟吧！你想戒掉很简单。只要你下定决心，就一定会成功的！销售香烟赞助商们，请你们为我们这个世界着想一下吧，少做一些香烟的生意，让世界变得更美丽些吧！
大家一起呼唤无烟环境，一起呼唤美丽的世界！
