Napoga is a 12-year-old girl in Ghana(加纳),Africa. It is hard for her family to get clean water. Every morning,she leaves home at half past five to get clean water for her family in a village far away. It takes her six hours to get enough clean water for daily cooking and drinking. She has no time to go to school or to play with her friends. Millions of people in the world are like Napoga. They can't get enough clean water to keep healthy.
Earth Day is April 22. But on all other days,we must also remember it. The water we use is the most important natural resource(自然资源) on the earth.
Water covers 70% of the earth's surface. But most of that is sea water. We can't use it for very many things. Fresh water covers only 1% of the earth's surface.
You probably feel lucky that your life isn't as hard as Napoga's. But that doesn't mean you don't have to worry about water. We all face serious water problems. One of them is water pollution. All kinds of things from cars,factories,farms and homes make our rivers,lakes,and oceans dirty. Polluted water is very bad for people to drink. And dirty water is bad for fish,too. Now, 34% of all kinds of fish are dying out.
How do cars and factories make our water dirty?First,they pollute the air. Then,when it rains,the rain water comes down and makes our drinking water dirty. Dirty rain,called acid rain(酸雨),is also bad for plants,animals and buildings.
Scientists say that in 30 years,more than half of the people in the world won't have enough clean water. We have to learn how to save more water for ourselves and our children. Here is some advice for saving water:
●Turn off the water while you brush your teeth. You can save as much as 450 liters(升) each month.
●Leaky taps(漏水的龙头) waste a lot of water. Fix them right away!
●You can easily cut your 10-minute showers in half----and you'll be just as clean.
●When you wash dishes,don't let the water run.
●Only wash clothes when you have a lot to wash. If your washing machine isn't full,you're  wasting water!
【小题1】On the earth,_______.

A.sea water is more widely(广泛地) used than fresh water

C.there is 71% of fresh water
D.we don't need to worry about water

A.is only bad for living things
B.can be produced in factories
C.doesn't do harm(伤害) to people,but it's bad for plants,animals and buildings

A.We need ten minutes if we want a clean shower.
B.We should put in enough clothes when we wash them in washing machines.
C.You can keep yourself clean by having a shower for five minutes.

Have you ever complained why life is so tiring? Does the sky sometimes seem dark to you? Are your studies sometimes not successful? Well, friends, cheer up and smile all the time. If you see the world with your warm heart, you will find the whole world smiles to you.

While in school, sometimes you are tired of your lessons, but have you ever noticed the happy smile on your teacher’s face when you did a good job?

One day it is fine. Just before you want to go out, it suddenly starts to rain. Maybe you would feel very sad and start complaining about the weather. But dear friends, why don’t you sit down and listen to the concert that the nature offers you? And with the timely rain, crops in the fields will grow better and better and farmers will have a good harvest.

Although everyone wants to succeed in what he tries to do, sometimes failure can’t be avoided. I think failure is not terrible, and the terrible thing is what we are afraid of it and give up hope. When we face failure, we must be confident in ourselves, draw a useful lesson from it and try our best to finish what we have decided to do. As a popular saying goes, “Failure is the mother of success.”

Attitude decided everything. With an optimistic(乐观) attitude life is easy and pleasant. Let’s smile whatever we meet and the whole world will smile to us.

The population of the Earth is growing faster. It is important that we look after the Earth. We need it! The Earth gives us a lot of things. We also give the Earth a lot, but some of the things are not good.

In nature, when something dies, other animals and plants get food from it. Every animal or plant gives food for other animals or plants. However, animals can’t get food from many of the things that we ‘give’ the Earth. Animals and plants can’t eat metal, plastic and glass. These things will stay in the ground for many, many years.

         Some rubbish is very dangerous for plants and animals. In some places, many animals live together. One animal makes food for many more animals. If we put rubbish and chemicals in the water, the plankton(浮游生物) can die. If there isn’t any plankton, many animals have nothing to eat.

         So what can we do? Don’t leave any rubbish in the countryside! Don’t make so much rubbish!

         A. food            B. rubbish                        C. chemicals                   D. pollution
