The World's Water Shortage
     The world is not only hungry, but it is also thirsty for water. This may seem strange to you, since nearly    70 percent (百分比) of the earth's surface is covered with water. But about 97 percent of this huge
amount is sea water, or salt water. Man can only drink and use the other 3 percent the fresh water from
rivers, lakes, underground, and other sources (资源). And we cannot even use all of that, because some
of it is in the form of ice-bergs and glaciers (冰川). Even worse, some of it has been polluted.
     However, as things stand today, this small amount of fresh water is still enough for us. But our need for water is increasing (增加) rapidly almost day by day. Only if we take steps to deal .with this problem
now can we avoid (避免) a severe (严重的) worldwide water shortage later on.
     We all have to learn how to stop wasting our valuable water. One of the first steps is to develop ways
of reusing it. Today in most large cities, water is used only once and then sent out into a sewer system (下水道). From there it returns to the sea or runs into underground storage tanks. But it is possible to pipe
used water to a purifying (净化) plant. There it can be treated with chemicals so that it can be used again,
just as if it were fresh from a spring.
     But even if every large city purified and reused its water, we still would not have enough. All we'd have   to do to make use of the vast reserves (贮备) of sea water in the world is to remove the salt. If we take these steps we'll be in no danger of drying up.

     1979 was World Conservation (自然保护) Year. The United Nations wanted everyone to know
that the world is in danger. They hoped that governments would go into action (采取行动) quickly  
in order to conserve nature. Here is one example of the problems. At one time there were l,300
different plants, trees and flowers in Holland, but now only 860 remain. The others have been
destroyed by modern man and his technology (技术). We are changing the earth, the air and the water,
and everything that grows and lives. We can't live without these plants. lf we continue like this, we will
destroy ourselves.
     What will happen in the future? Perhaps it is more important to ask "What must we do now?"
The people who will be living in the world of tomorrow are the young of today. A lot of them know
that conservation is necessary. Many are helping td save our world. They plant trees, build bridges
across rivers in forests, and so on. In a small town in the United States a large group of girls cleaned
the banks of 11 kilometers of their river. Young people may hear about conversation' through a record
called  No one's going to change our world. It was made by the Beatles, Cliff Richard and other singers.
The money from it will help to conserve wild animals.

     Plants are very important. This is because plants can make food from air, water and sunlight.  
Animals and man can't make food from air, water and sunlight.  Animals can get their food by eating 
plants and other animals.  Man gets his food by eating plants and animals, too. So animals and man 
need plants in order to live.  This is why there are so many plants around us.     
     Plants are classified (分类) into two kinds-flowering plants and non-flowering plants. Almost all 
the trees around us are flowering plants. You can know some trees from their flowers and fruits. 
Non-flowering plants do not grow flowers. You can't see many non-flowering plants around you.  
If you look at the plants around you carefully,  you. will find that there are many kinds of plants. Some 
plants are large and some are small.  Most of them are green.  Thanks to the plants around us,  we can 
live on the earth.

    Nowadays more and more people in the world are getting fatter, which troubles them a lot. In the past 25
years, the number of the people with obesity (肥胖症) in Europe has doubled. Experts say that it has a lot to
do with our eating habits.
    Our eating habits are very important for good health and a strong body. Most of us like eating sweets and
ice cream better than meat and rice. Sweets and ice cream are not bad for us if we eat them at the end of a
meal. If we eat them before a meal, they may take away our appetite (食欲).
    It's important for us to eat our meal at the same time each day. When we feel worried or excited. We may
not want to eat. A long time ago, in England,some judges often decided whether a man was telling the truth
by giving him some dry bread. If the man could not swallow the bread, it meant that he wasn't telling the
truth. A man who is worrying something has difficulty in swallowing anything dry, because he loses his
appetite

     Do you know you could get sick just by walking past a building? The bacteria (细菌) that cause
Legionnaire's disease grow very fast in large modern buildings. They are carried by air through the buildings
and outside. Legionnaire's disease is only one of the illnesses that are caused by "sick buildings".
     Some buildings can make you ill because their heating and air-conditioning are controlled. Air from
outside cannot get in through the closed windows. This indoor air pollution is a growing problem.
     Legionnaire's disease, which can kill, is probably the most serious result of sick buildings, but other
unpleasant illnesses can appear. People who work in some buildings suffer from tiredness, feeling sick and
headaches. Their offices look bright and clean, but invisible (无形的) and dangerous bacteria are in the air
around them.
     There is an answer to the problem. The air-conditioning and heating can be tested for bacteria. Once the
tests are complete, the sick building can be cured (治愈). This is expensive to do, but the results are good.
"The people in the buildings no longer get sick, and everybody is happier.
