Napoga is a 12—year---old girl in Ghana, 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(自然資源)on the earth.
Water covers 70 perent of the earth’s surface (表面). But most of that is sea water. We can’t use it for very many things. Fresh water covers only one percent 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, thirty-four percent 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 450liters(升)each month.
● Leaky taps （漏水的龍頭）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 are wasting water!

If you go to Finland, you’ll be surprised to find how “foolish” the Finnish people are.
Take the taxi drivers for example. Taxis in Finland are mostly high class Benz with a fare (票價) of two US dollars a kilometer. You can go anywhere in one, tell the driver to drop you at any place, say that you have some business to attend to, and then get off without paying your fare. And the driver would not show the least sign of worry.
The dining rooms in all big hotels not only serve their guests, but also outside diners. Hotel guests have their meals free, so their good faith is to wave their registration card to the waiter. With such a loose check, you can easily use any old registration card to take a couple of friends and dine free of charge.
With so many loopholes (漏洞) in everyday life, surely Finland must be a heaven to those who love to take “pretty advantages”. But the strange things is, all the taxi-passengers would always come back to pay their fare after they have attended to their business; not a single outsider has ever been found in the free hotel dining rooms. As the Finns always act on good faith and always show an attitude of “which is which” and “what is what” in everything they do, so to live in such a society has turned everyone into a real “gentleman”. In a society of such high moral practice, what need is there for people to take precautions (預防措施) against others?
【小題1】The word “foolish” probably means _____________.

A．friendly　　　

B．careful　　　

C．strange　　　

D．funny

【小題2】Why wouldn’t the driver show the least sign of worry? Because _________.

A．he is sure that the passengers always act on good faith

B．he is afraid to make the passengers angry and unhappy

C．he thinks the passengers may be too poor to pay him

D．he is sure that the passengers are really in trouble

【小題3】The dining rooms in all big hotels ___________.

A．check the guests’ registration card carefully

B．give people meals without paying

C．serve their guests free of charge

D．only serve their guests free breakfast

【小題4】What’s FALSE according to the passage?

A．No one takes advantages although there are many loopholes.

B．All the taxi-passengers come back to pay their fare after they have attended to their business.

C．Not a single outsider has ever been found in the free hotel dining rooms.

D．Finland is heaven for immoral people because they can always take advantages freely.
