water is very important for living things. without water there can be no life on earth.
as we can see, the world population is growing rapidly day by day. so enough fresh water is needed to feed such a big population. what's more, with the development of industry, factories and vehicles produce poisonous gases or wastes, which consequently results in the pollution of water. though fresh, a good amount of it can no longer be used. only quite limited fresh water resource is available to human beings. so it's high time for us human beings to take quick action to protect water resource. stop pollution and save water, otherwise, we cannot survive on the earth.
with fresh water, the world will be prosperous.
water is the source of can't live without ver,with the increasing population and industrial development,water pollution has become a serious e amounts of wastewater go into rivers and seas directly without being treated,which can be dangerous to 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 ories should treat the wastewater before letting it go into can play a positive role in saving example we can reuse the water for wishing rice to wash vegetables and then clean a mop.
water is indispensable to our life and the development of national economy. it is often described as the source of all living things and the lifeblood of agriculture and industry. without it, nothing could grow and out world would become a terrible desert.
the world we live in is now faced with a severe shortage of fresh water. according to some official figures, more than 1,700 million people in the world don't have enough clear water to drink and over 25 thousand people die of water related diseases daily.
so, all of us should actively b save water. it's our obligation for the benefit of the future generations.
Crisis is to our life what illness is to our body. Just as fatal disease can destroy our body and sometimes even put an end to our lives, so does smashing crisis knock us down so hopelessly that we might never have chance of standing up again. However, most crises that frequent us in life are not such category. They, like occasional ailments which sometimes can bolster our body's immune system, are mostly minor and surmountable and therefore making us hardy enough to survive whatever adversities in our later life. Even those serious crises, if handled properly, can be turned to a blessing to us, too.
As far as a nation is concerned, crisis can be rendered beneficial. Take Wenchuan earthquake which shook most of Sichuan recently for example. The crisis has cost us Chinese a lot. Houses collapsed, bridges broke down and many affected areas were cut off from the outside world. Nearly a million people lost their homes, ten thousands of people were injured and another ten thousands of people were killed. But our sufferings won't go in vain. Scientists are more determined to improve the means by which we forecast earthquakes with more accuracy. We should build houses which can survive the destructive earthquakes. And we also should better the mechanism to face the emergencies and crisis.
As for economic life, crises are not always rendered bad. During these times, we can stop the race of fast economy to speculate about some fundamental issues of humanity such as how much high-speed development in this way can contribute to the well-being of human life. Just take my own country for instance. Of course, in the past two decades or so, our economy has gained the highest speed man has experienced. But haven't we paid too much? Our rivers are polluted. Our natural resources are shrinking. Our national power of creation is drained. Is it worthy of it? Isn't it high time we gave it a serious thought? Shouldn't we stop making ourselves long in quantity and short in quality? And chance of deep thought has come with this crisis, which is now deepening in most parts of the world.
Crisis sometimes contributes to our life treasure in a way that few can imagine. It can weather us and make us strong enough to face ourselves when we feel weak. Eric, my uncle is a case in point. He had hard time in his childhood going through such a fatal disease that he had never thought he could survive. He was in due course saved by doctors. Ever since then he regarded his life as a second given by God and has been so grateful to the world that he has been doing whatever he can to give back in the same measure to other fellows. And now he is living a happy and successful life.
As a well-known ancient Chinese notion goes, the past lessons if not forgotten can be good teachers for us all. If we can bear in mind the various sufferings and ordeals we have experienced, then our sufferings will not go unrewarded and those of our compatriots who was killed in the earthquake did not die in vain. We should take the lessons from crisis and regard them as a chance for new growth.
