Water is so important to people that we can't live without it. Water is the source of life. If there is not enough water, our life will be difficult to go on. For example, it has little rain in some places. Farmers there don't have enough water for growing rice and vegetables. So people in the city may not get enough food.
There's much water on the Earth, but most of it is salty ocean water. In fact, most of the water in the world is not fit to drink. Groundwater is fresh and drinkable, but it is very easy to be polluted. At the same time, it is not easy to clean up dirty or salty water. So it is very important to save water. Here are the things we can do in our daily lives.
Don't leave the water running when we brush our teeth.
Take a shower instead of a bath, because taking a bath uses much more water than a shower—about twice as much. What's more, we can take shorter showers.
We can clean the floor with the water used for washing vegetables.
Battery is used in families and machines. The chemicals inside it produce electricity. It's quite convenient for humans' lives. Now an old battery is getting a makeover (改造) and can give electric cars more energy to run. The nickel-iron (镍铁) battery was created over 100 years ago and now scientists in Harvard University have improved it to give off energy quickly. This can help electric cars run faster. What's more, this kind of battery is less harmful than the common (平常) ones. This new kind of battery hasn't been used in daily lives, but people are all interested in it. Scientists say they are working hard to put it into market as soon as possible. They believe that the battery will make another great change for people's lives.
Why is clean water so important to poor countries? A recent report shows that about 80 percent of diseases. in poor countries are brought by polluted water and the dirty environment. In those countries, women and girls spend several hours collecting water, but often polluted, far away from their families. The polluted water is bad for their health. Therefore, there is a great need for people in poor countries to get clean water to improve their health.
Here is a short story about Hadjara Zakari, a 12-year-old girl in Niger. She learned about the importance of hand washing when the school first got clean water three years ago. That evening, she told her father, “You shouldn't eat with me unless you clean your hands.” Her father was very angry and shouted at her, "It's not up to you to tell me what to do!" Stunned (目瞪口呆的) , Hadjara sat quietly. But she knew she was right. In protest, Hadjara didn't eat dinner that night. After her father asked Hadjara's head teacher, he understood the importance of hand washing and his daughter's intention (目的). The girl really wanted her family to live longer and healthier lives.
For people in developing countries, clean water can change many things, especially improve their health. So, from now on, let's avoid wasting water and take action to save water, which is important to people all over the world.

more than square kilometer other place come from as a result |
Shenzhen's fast development has made it become China's most crowded city! There are about 13 million people living on its area of 1,997. On each square kilometer averagely (平均地) live 6,510 people. It is about 4,560that in Guangzhou. Besides, Shenzhen owns 2 million local vehicles, and about 300,000 vehicles fromalso run on the local roads every day. The total length of the city's road is about 6,000 kilometers. It means each resident only owns about 0.46 m of road!, the city. is facing serious environmental and resource (能源) problems. One of the problems is water shortage. The amount of fresh water for each person of the city is only 25% of the country's average. What's more, most of the water drunk by Shenzhen peopleother areas.
Although the world is hungry, it is even thirstier. While nearly 3/4 of the earth is covered with water, we are short of drinking water.
How can we avoid (避免) a serious water shortage? Then, we should protect our water resources and not pollute them. Lastly, we should discover ways to reuse water. But people's need for water is increasing day by day. We still don't have enough water. What else can we do?
There is plenty of water in the sea. But we need to take the salt away from the sea water. If scientists can find cheaper ways to do it, we can solve the problem of the shortage of water.

A. First, we should save water and not waste it. B. This is very expensive. C. Scientists have got some achievements in this field. D. The sea seems to have the best answer. E. This is because about 97% of the water on the earth is sea water. |
