We all have to learn how to stop wasting our limited water. One of the steps we should take is to find ways of reusing it. Experiments have already been done in this field.
Today in most large cities, fresh water is used only once, then it runs into waste system. But it is possible to pipe the used water to a purifying factory. There it can be filtered and treated with chemicals so that it can be used again, just as it were fresh from a spring.
But even if every large city purified and reused its water, we still would not have enough. Then we could turn to the oceans. All we’d have to do to make use of the seawater on earth is to get rid of the salt.
This process is called desalinization, and it is already in use in many parts of the world.

Scientists, for several years, have been studying how noise affects people and animals. They are surprised by what they have learned. Peace and quiet are becoming harder to find. Noise pollution is a threat that should be looked at carefully.
There is a saying that it is so noisy that you can't hear yourself think. Doctors who study noise believe that we must sometimes hear ourselves think. If we don't, we may have headaches, other aches and pains, or even worse mental problems.
Noise adds more tension to a society that already faces enough stress.
But noise is not a new problem. In ancient Rome, people complained so much about noise that the government stopped chariots(战车) from moving through the streets at night!
Ways of making less noise are now being tested. There are even laws controlling noise. We cannot return to the "good old days" of peace and quiet. But we can reduce noise—if we shout loudly enough about it.
Why are scientists surprised by the findings in their noise study？
A．Because the world is becoming increasingly noisy.
B．Because they have learned that noise is also is also a kind of pollution.
C．Because noise is an unwanted waste for human beings.
D．Because people knew little about noise before.

Other reasons they take that first drink are to be rebellious(反抗的), for curiosity or "kicks" (刺激)or to escape an unpleasant environment; And young people drink use drugs because alcohol(酒精) and drugs are at hand.
After first experimental use, young people continue to drink or use drugs because they believe these substances can relieve boredom, increase energy, decrease anxiety, solve problems, or help them socially. They may simply like the "high" they get in the early and middle stages of substance use. After continued use, they will become physically and psychologically(心理地)addicted(上瘾的).
