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 icebergs 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. |

Young people should be enjoying the best time of their lives, but those in their twenties and thirties
are in worse health than their parents, a British survey has found.
Drinking too much, eating fast food and being short of exercise all have a bad influence on young
people. As a result, the young are more likely (可能的) to have headaches, catch colds or become
stressed than their parents.
According to the survey, those aged between 18 and 34 are three times more likely to catch colds
than the older people. The following are the main reasons:
The old people usually eat more healthily. More than four in ten old people eat five or more portions (份) of fruit or vegetables a day. It"s two times the number of the young men and women. Six in ten old
people cook their own meals every day, compared to less than one third of the young people. Almost
10% of the young people admit (承认) that they eat fast food for every meal and 2% say they only eat
at restaurants.
The old people are also more likely to take a lot of exercise. 12% of them spend at least 30 minutes
doing exercise each day. They are healthier. However, only 9% of the young do so.
