Every time you turn on the television or take a ride in a car,you could be adding to a problem 66     acid rain. In this article，you’ll learn how acid is created，and how it affects us，and more importantly,what we all can do 67      it.

How is acid rain created?

When people use fuels (燃料），such as coal and gasoline,poisonous gases are given off. When these gases mix with rain,acid rain forms. Many power stations burn fuels in order 68      the electricity (电)that we use in our homes and offices every day. Cars and trucks also send these gases into the air when they bum gasoline. When rain mixes with these gases,69      things called acids form. This is acid rain.

How does acid rain affect us?

Acid rain damages everything  that it touches. It poisons our rivers,ponds,lakes,and oceans  along  with all the

life in them. It 70      our soil and crops,harms trees,and can even kill fish and plants. Acid rain  also  71       away

at buildings.

How can we prevent acid rain?

We need 72      on the pollution that gets into our air. Turn off lights,televisions,and 73      electrical appliances if you are not 74      them,and walk or take a bike whenever possible. If you are travelling a long distance,take a bus or train to save fuel.

As research shows,acid rain  harms our environment. But people everywhere can take small  steps  now to help 75      our environment for future  generations.

  We live on the earth. We need the ocean around us. What do we take from the ocean? And what do we give to it? We take fishes from the ocean——millions of kilograms of fishes,every year,to feed millions of people. 61      We take minerals(矿物）from the ocean. We can get salt by evaporating(蒸发）seawater. 62      Many other minerals,such as gold，can be also got from the ocean,but not by simple evaporation. 63      Seaweed(海草)becomes food of many kinds—even candy,ice cream—as well as medicine. Believe it or not,fresh water is another gift from the ocean. We can’t drink ocean  water. 64      But ocean water becomes fresh water when the  salts  are removed.  In the future, we will find ourselves  depending more and more on fresh water from the ocean.

   The ocean gives  us food,fertilizer,minerals,water and other gifts. What do we give  to the ocean?  We pollute  the

ocean all the time.  65      Throwing waste into the ocean is killing off sea life. Yet  as the world population grows,we may need the ocean and its gifts more than ever. We are finally learning that if we destroy our ocean,we might also destroy ourselves. Hopefully,it is not too late.

When Oakland High School in California moved into a new building,the students and teachers noticed a strong smell. Then almost half of the students began to have a headache and a cough. Experts(专家)came to find the cause of the sickness. Finally,they discovered that the air in the building was not safe to breathe. They were surprised to find out

that the desks and chairs in the school library caused the trouble. These desks and chairs were made of particleboards

(合成板）.This kind of board is cheap. It is made of very small pieces of wood held together with a chemical (化学物

质). This is just one example of a modem problem that is most common in cities—indoor air pollution(污染).

People have worried about air pollution for many years，and the government has spent lots of money trying to clean

up the air of big cities. But now we found that we are still breathing unhealthy air. A study shows ： Indoor air pollution is

almost two to five times(倍)worse than outside pollution. So remember to open the windows and don’t stay too long in

modem buildings with windows closed.

  The world is not hungry,but it’s thirsty. It seems strange that nearly 3/4 of the earth is covered with water but we say we are short of water. Why? Because about 97% of the water on the earth is sea water which we can’t drink or water plants directly. Human beings can only drink and use 3% of the water that comes from rivers and lakes. And we can’t even use all of that,because some of it has been polluted.

Now more water is needed. The problem is how we can avoid a serious water shortage in the future. First,we should find out ways to reuse it. Scientists are making study in this field. Today,in most large cities water is used only once and then runs to the sea or rivers,actually it can be used again. Even if every large city reuses its water,the water will still not be enough. What could people do next?

The sea seems to give us the best answer. There is a lot of water in the sea. All that need to be done is to get the salt out of the sea water. This will be expensive，but it has already been used in many parts of the world. Scientists are trying to find out a cheaper way of doing it. So you see，if we can find out a way，we’ll be no longer in danger of drying up.
