1．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（衛(wèi)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（有機(jī)會或權(quán)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．
