  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(日常)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(表面).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 plant s, 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 tap 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!

Venice is an attractive city in Italy. Tourists throughout the world love traveling to Venice. But sometimes you’ll have such strange experiences. One moment you walk across the Rialto Bridge, and there’s nothing special. Unfortunately, when you come back to the bridge an hour later, it’s underwater and everyone’s wearing rain boots.
That’s just the way it has always been, which may be considered seriously by Italian government. Before the sea comes to Venice, the government has decided to build the MOSE gates. Actually(实际上), there were many kinds of gates that were built to stop the floods, but all the gates were just built on the ground. Besides, the flooding was becoming worse. Industrial(工业的)factories built nearby on the mainland also made the condition get worse, causing the city to sink about 0.75 feet in the 20th century.
So the Italian government asked some of Italy’s biggest construction and engineering companies to build the MOST project, which was planned to be built under the sea water to stop floods. Now the government are using 3 000 people and expect to spend nearly five billion euros(欧元) on it. The MOSE gates are being built at the inlets(海湾).Each MOST gate is 197 feet long ,28.5 to 37 feel tall, and weight up to 22 tons. It’s nearly the size of a 20-story building. Before the gates are in use, under the sea full of water. When the flood comes, the water in the gates will be poured out, and then the gates will be filled with air. So the gates can go up with the sea water. Once they’re in the right place, they will stop the sea water pouring into Venice. These gates will be able to deal with floods up to 10feet,and as long as the sea level(平面)rises no more than two feet in the next 100 years, the MOSE will work as expected.
The MOSE project is now two-thirds done. The head engineer, Giovanni Cecconi, said, “This is a war. During the war, it’s not important that you win. It’s important that you’re alive. We’ve alive.” Anyway, this project is saving Venice from falling.

Have you ever beard of Iceland? Iceland is a country, one-tenth of which is covered with ice. However, it is said that Iceland is the land of heat. Smoking volcanoes (火山), white steam (蒸汽) and hot springs are more amazing than the other sights including ice there.

    It has taken millions of years for volcanoes and lava flows (熔岩流) to build Iceland. When hiking through one of Iceland’s many ancient lava fields, you may notice something strange. White steam is rising from each vent in front of you. Iceland is covered with vents which steam can pass out of. The steam comes from naturally heated rocks and hot water below the Earth’s surface (表面).

    Like steam vents, hot springs can be seen here and there in the ancient lava fields. Blue Lake is the most famous hot spring in Iceland. It isn’t far from the capital city of the country. The water and white earth in it can make your skin as soft as a newborn baby’s skin. Enjoy that water, because it has traveled a long way. It starts nearly two kilometers under Blue Lake. There, water from the ocean continues moving up slowly into the spaces between hot rocks below the surface. And then the water is heated by hot rocks. Powerful machines and long pipes (水管) help bring the heated water to the surface. People in Iceland use natural hot water for hot springs. Besides, they use it to create electricity that can be used to heat homes and even greenhouses.

    Iceland is one of the few places on the Earth where active volcanoes lie below ice. Heat from the volcanoes creates a strange and wild beauty. Therefore, some people believe that it’s better to call the country “Heatland” instead of Iceland. If you have a chance to travel there, take it.
