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 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. 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 rapidly - almost day by day. Only if we take steps to deal with this problem now
can we avoid a severe 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 tank"s. 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. |

Quitting smoking can be hard. It is much easier not to start at all.
One of the reasons that young people smoke is because they think it is cool. Cool people sometimes
smoke a lot in movies, but you may not know that in real life some stars like Jackie Chan think smoking
is bad. Chan doesn"t think it is cool at all!
And sports stars like Yao Ming don"t smoke cigarettes, but they are very cool.
Sometimes people start smoking because their friends ask them to do so, or they see other people like
their parents doing it and think that it"s OK. But if other people jumped off a bridge, would you follow them? Of course not,
Some people think that smoking can stop stress. But there are better ways to beat stress.
Exercise is one way. Exercise relaxes your muscles. Next time you feel stressed about school, go for a
run!
Exercise is also a good way to help you quit smoking if you have already started.
Go for a long walk without money or cigarettes, and breathe in the air around you. Maybe take some
lunch and stop in a park, and think about how much better you feel without a cigarette in your mouth.
Also think about the money you will save by not smoking. You can spend it on much more fun things
like music, clothes or nice food.
To stay away from smoking, or to help quit, keep a list with the reasons why smoking is bad.
If you want to quit, tell your friends so they can help you. If they"re good friends, they will
help.
Millions of people have already quit smoking. It is not difficult if you try hard!

me. However, it is largely their own fault (过错) . A tired person may get caught when he goes to
the crowded places with polluted air. An unexpected change of the weather can also make me catch
them. In hot summer, people turn on the air conditioner (空调) when they return home. They will
catch a cold easily.
My last victim is an energetic student. After school, he played football for about two hours. Though
tired, he still went to the cinema. Then he got back home and took a cold shower right away.
I found him easily then. He kept sneezing and his nose was running. Although he put on some warm
clothes, it didn"t work. The next day, he couldn"t go to school. He had lost his appetite(食欲) and he ate
much less than before. His mother made him drink a grass of orange every few hours for more Vitamin C.
For two days he was nursed by his mother, and I began to feel weak. I knew I had to leave him
before long. Because of his defense system (防御系统) was starting an all-out attack(袭击) against me,
I became weaker and finally my time was over.

body needs energy to work. Where does energy from? It"s from the food you eat every day. But it"s not
from one kind of food. It needs many different kinds of foods. To balance your diet, you should try to eat different foods. You are what you eat. For example, if you eat too much meat but little other foods, you
will be fat. In fact, our body needs nutrients (营养) from many kinds of food like meat, vegetables, fruits
and sugars. Don"t forget to brush your teeth after eating sugars, because sugars are bad for your teeth. | | 阅读短文，判断T列句子正(T)误( F) 。 | | ( )1.
