The world is not only hungry but also thirsty for water. This may seem strange to you, since nearly 70%of the earth's surface is covered with water. But about 97%of that is sea water or salt water. Man can only drink and use the other 3%of fresh water from rivers, lakes, underground and so on. And we can not even use all of that because some of it has been made dirty.
Earth Day is April 22. But on all other days, we must also remember how important water is. The water that we use is the most important natural resource on the earth. Today we face serious water problems. One of them is water pollution. All kinds of things from cars, factories, farms and homes make our rivers, lakes and oceans dirty. Polluted water is very bad for people to drink. And dirty water is bad for fish, too.
How do cars and factories make our water dirty? First they pollute the air. Then when it rains, the rain water makes our drinking water dirty. Dirty rain, called acid rain（酸雨）, is also bad for plants, animals and buildings. Scientists say that in 30 years, more than half of the people in the world won't have enough dean water. We have to learn how to stop wasting water. One of the first steps is to develop ways of reusing it. Today in most large cities, water i~ used only once and then sere out into a sewer system（下水道）. From there it returns to the sea or goes underground.
But even though every large city reused its water, we would still not have enough. So we should make use of sea water by removing the salt in it. If we can take these steps, fresh water won't be used up.

B
Different countries have many different kinds of climate (气候)．And in one big country people in different areas may often have different kinds of climates as well.
The United States has many different kinds of climate.On the northwest coast (海岸)，the temperature changes very little between summer and winter.It is not hot or cold all the year around.But the people in the north central states have a very different kind of climate.In those states，people wear light clothes in summer，and in winter they need to wear heavy woolen clothes.
In the southwest coast of the United States，temperatures in summer are very different from those in winter.Summer is usually hot，and winter is usually cold.In spring the temperatures are warm，and in fall temperatures are cool.Many years ago，people in the cold parts of the United States didn't often get fresh vegetables and fresh fruits during the summer.Today，however，trucks and trains carry fruits and vegetables very quickly to the cold parts of the United States.In this way，Americans“send their climates”to people in other states.
