许多人把地球想象为一个蔚蓝色的星球，其实，全球淡水资源不仅短缺而且地区分布极不平衡。按地区分布，巴西、俄罗斯、加拿大、中国、美国、等9个国家的淡水资源占了世界淡水资源的60%。约占世界人口总数40%的80个国家和地区约15亿人口淡水不足，其中26个国家约3亿人极度缺水。随着科学事业的逐渐发展，厂房高楼的逐渐增多，水短缺问题越来越严重。随着人类的破坏，原来的那个蔚蓝色的“水晶球”已经不再明澈，不再蔚蓝了，即将干枯。如果还不珍惜，最后一滴水将与血液 Many people think the earth for a big blue planet, in fact, global freshwater resources shortage and not only in the uneven distribution. According to the regional distribution, Brazil, Russia, Canada, China, the United States, and nine countries of freshwater resources for 60% of the world's fresh water. Accounts for about 40% of the world's population of 80 countries and region about 1.5 billion population fresh water shortage, of which 26 countries of about 300 million people was desperate.Along with the science of career development gradually, the factory workshop in a building increases gradually, the water shortage problem more and more serious. With the destruction of the human, the original big blue "crystal ball" is no longer clear che, no longer blue, is about to dry. If still do not cherish, the last drop of water will and blood

Water is the source of life.We can't live without water.However,with the increasing population and industrial development,water pollution has become a serious problem.Large amounts of wastewater go into rivers and seas directly without being treated,which can be dangerous to people.Also lots of people pay no attention to saving water in daily life,while in some place water is badly needed. It's time for us to take some measures to improve the situation.Factories should treat the wastewater before letting it go into rivers.We can play a positive role in saving water.For example we can reuse the water for wishing rice to wash vegetables and then clean a mop

Water is very important to the human beings.But now many rivers and lakes are polluted.
And what shall we do ? We can do like this:
First we must prevent the factory from pouring waste water into the river
Second we should stop people from throwing litter into the river.Many kinds of litter may pollute the environment.
Finally we can tell the visitors how important the water is.
After doing these things,I think water will become cleaner sooner or later.
水是对人类非常重要.但是现在许多河流和湖泊受到污染.
而我们该怎么办?我们可以这样做：
首先,我们必须防止工厂将污水倒入河流.
其次,我们应该阻止人们把垃圾扔进河流.各种垃圾会污染环境.
最后,我们可以告诉参观者,水是多么重要.
做了这些事情后,我认为水将迟早变得更清洁.
保护水资源
SAVE water ! In my lifetime I saw many people waste our sources . You like , the coal , steels and so on . Today I want to show the water .
We all know that water is our indispensable source . People can not survive without water . But as I said I saw people did not close the water pump when they left . And this is not the only ting I saw .
So , I suggest that we people should take great action to protect it . For example , we plant trees and grass to keep the earth hold on . We also reduce the water pollution from the factory !
that's all I wish that make our earth more water more hope .
保护水资源
I found that some children like to play with water, make some waste water.
Water is an indispensable part of human. People can not eat for three days and but not 3 days without drinking water. The water on the earth is very rich, a total of 1.45 billion cubic kilometers. But, of which 97.5% is salt water, can not be human use directly. The earth's fresh water accounts for only 2.5% of the total water resources, but, in these fresh water, 87% is difficult to use. Human can really use of water, about 0.26% of the earth's water. More terrible is that by 2025, there will be 3 billion people the world face water shortages, 40 countries and regions to a serious shortage of fresh water. China's total water resources of 2.8 trillion cubic meters. In accordance with internationally recognized standards, per capita water resources is less than 3000 cubic meters for mild water shortage; Water resources per capita is less than 2000 cubic meters for moderate water shortage; Water resources per capita is less than 1000 cubic meters for severe water shortage; Water resources per capita is less than 500 cubic meters of water. China now has 16 provinces, city, district water resources per capita is lower than the severe water shortage, there are six provinces and districts (ningxia, hebei, shandong, henan, shanxi, jiangsu) water resources per capita is less than 500 cubic meters. Visible, the water is how precious!
Let's save water, cherish our essential thing - water!
我发现有些小朋友喜欢玩水，使一些水白白浪费掉。
水是人类不可缺少的一部分。人可以3天不吃东西，但不可以3天不喝水。地球上的水是很丰富的，共有14.5亿立方千米之多。但是，其中有97.5%是咸水，不能被人类直接利用。地球的淡水资源仅占总水量的2.5%，可是，在这些淡水中，又有87%难以利用。人类真正能够利用的水，约占地球总水量的0.26%。更可怕的是，预计到2025年，世界上将会有30亿人面临缺水，40个和地区淡水严重不足。中国的水资源总量为2.8万亿立方米。按照国际公认标准，人均水资源低于3000立方米为轻度缺水;人均水资源低于2000立方米为中度缺水;人均水资源低于1000立方米为重度缺水;人均水资源低于500立方米为极度缺水。中国目前有16个省、市、区人均水资源低于重度缺水线，有6个省、区(宁夏、河北、山东、河南、山西、江苏)人均水资源低于500立方米。可见，水是多么珍贵的呀!
让我们节约用水，珍惜我们必不可少的东西水吧!
