1Water is a precious resource.Although we are surrounded by it in oceans,lakes,rivers and streams,our supply is limited.The chart given shows that most of the water on earth — 97.4 percent — is salt water stored in oceans.Only 2.6 percent of the earth's water is fresh water,and 2 percent is locked up in ice caps and glaciers.Thus the fresh water left for us to use is only 0.6 percent of the total water supply.
There will never be any more fresh water than there is now.In fact,the earth is short of fresh water.Besides,the increasing growth of the world population,the growing demand of industry for water,the serious pollution of our environment all this makes the world in danger of running out of fresh water.In some large cities such as Tianjin,fresh water cannot meet the daily needs.
Since water is essential to all life and the supply limited,we must manage it intelligently and carefully.

Too much homework has become a common complaint in high schools and elementary schools.Students have to spend most of their time doing homework,even on weekends.As a result,they have no time for their hobbies,or for their parents or friends.All they do is what they have to do,not what they like to do.The underlying cause for this phenomenon lies in the present exam-oriented education system.National College Entrance Examination has become the sole focus of teachers,parents,and students themselves.High score becomes the ultimate goal,to the neglect of practical abilities,personality development,and all that.
It is urgent that we deepen our educational reform.We must allow for students' overall development,not just evaluate their test scores、
