Colorful hair speaks more about beauty. Now it becomes popular and people are dyeing their hair to make it different. Dyeing hair with natural products is good for health while dyeing with chemicals is harmful. Researches have found that dyeing hair with chemicals can make people have cancer.

? It is better to apply hair dye for a few minutes. If you leave your hair with dye, longer than the necessary time,then you may get some skin problems.

hands.
? After applying hair dye it is important to wash your hair with water.

  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!
根據(jù)材料內(nèi)容,選擇最佳答案,并將其標(biāo)號填入題前括號內(nèi)。
小題1:Every morning Napoga went to get clean water _________.
A.before she went to school

What do you think is the most important invention in the world? The TV? The printer? The telephone? Or the computer? A report shows that they are not the only important inventions. Here are three other important inventions.
One of the simplest inventions is the toilet. Before toilets, people poured or dumped waste into rivers from people’s houses. Illnesses were common in big cities, and it was often difficult to find clean drinking water.
Animal food is another important invention. Before the invention, most animals were killed every autumn because there was not enough food for them in winter. After hay(干草) became a kind of common animal food, animals could live through the long winter.
The third great invention is glasses. Glasses help people read, write and do “close work” after the age of 45. Without glasses, the word would be difficult for the people above 45.
