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！

Last year in the UK at least 45 people died and 900 more were injured in car accidents where drivers were using their mobile phones.Yet many people continue to use them while driving even though it’s dangerous.
Research has shown that it is difficult to concentrate 0n driving and talking at the same time.It can even be more dangerous than driving after drinking too much.A recent study found that when drivers were talking on their mobile phones，their stopping times were 30 percent slower than when they had drunk too much—and nearly 50 percent slower than when they were driving normally.It also found that drivers talking on mobile phones were less able to control their cars than drunk drivers.
And talking isn’t even the most serious problem, texting is. Unbelievably, another recent study reported that 22％ of adults admitted they had sent a text message while driving at least once in the past month.An average text message takes 90 seconds to write and send.That means for one and a half minutes a driver is looking at their phone’s screen and not at the road.The arrival of new smart phones such as the iPhone will only make matters worse as they will allow users to do more things than ever before.
Using a mobile phone while driving puts others’ lives at risk.No matter how well we drive，if another driver is not being professional or careful，we are put in danger by their actions.Such drivers are selfish，careless and should have their driving licences(驾照)cancelled.
There is no doubt that mobile phones call be fun and are extremely useful，especially when you’re in trouble.But there is no need to use them while driving.Just wait until you stop or you will probably get into trouble of your own.
