    Why is clean water so important to developing countries? A recent report shows that about 80 percent of diseases in developing countries are caused by poor water and low sanitation（卫生）conditions. In those countries, women and girls spend several hours collecting water, but often polluted, far away from their families. The polluted water more or less influences their health. In this case, there is an urgent（迫切的）need for people in developing countries to have access to（有机会或权利使用）clean water to improve their health.

    Here is a short story about Hadjara Zakari, a 12-year-old girl in Niger. Having access to clean water changed her life. She learned about the importance of hand-washing when the school first received 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 in silence. But she knew she was right. In protest,Hadjara refused to eat dinner that night. After her father questioned Hadjara's head teacher, he understood the importance of hand-washing and his daughter's intentions（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.

    Are you still worried about how to get your phone charged (充电) ? Now, a 19-year-old teenager can help you to solve this problem. He has invented a phone charger which uses energy from your own body to charge your phone.

    Hand Energy, the wonderful invention of the inventor Miehael Vaga, allows you to charge your phone simply by shaking your hand, which starts the charger's gyroscope(陀螺仪) to produce electricity. And the electricity can then either be stored or used to charge a mobile immediately (立即).

    He said, " With each rotation (旋转) of your hand, the gyroscope's speed increases quickly and produces more power. The average (平均的) speed of the gyroscope is about 5, 000 rounds per minute. With this small charger, your physical energy can be turned into electrical energy and this means you can charge your phone. "

    Hand Energy can help you produce endless electricity.  You can use it everywhere you want. It is especially useful for people who have to spend a long time in the wild. What's more, it's friendly to the environment and helps you to exercise your wrists. It takes between 40 minutes and one hour to fully charge the batteries(电池) in Hand Energy.

    The invention took Vaga a year to develop. Now, the inventor from Minsk, Belarus, is ready to put it into production and send out the creative convenient chargers.
