    March 20th is World Water Day every year. According to a report from the United Nations, more than half of the world's major rivers have serious water loss and are polluted.

    The Yellow River, the world's fifth longest river, watered some of the oldest farms on earth. {#blank#}1{#/blank#}Its source（源头）on Qinghai-Tibet Plateau is drying up. In most of the past 35 years, it didn't reach the sea.

The Nile in Egypt, running 6, 650 km, is the longest river in the world. {#blank#}2{#/blank#}Now it is down to 2 billion m³ or so. Australia's Murray River reaches the sea only every other year. One fifth of America's Rio Grande has no water, either.

    {#blank#}3{#/blank#}

    Mostly it's damming（筑坝）and global warming that make rivers dry. {#blank#}4{#/blank#}Now about 45, 000 of them lie across the world's rivers. They hold back around 15% of the world's fresh water from running to the sea.

    A city without cars would be very strange, right? But Venice is such a city.

    Venice is in the northeast of Italy. It isn't built on land, like Beijing or Shanghai, but on more than 110 islands. Seawater is everywhere around the city.

    Even so, travel isn't difficult. The waterways have always been the best way to get around. There are 117 waterways and more than 400 bridges that can lead you where you want to go.

    People in Venice move from place to place by boat. They like to enjoy cool summer nights while taking boat trips. They can talk to other people as they go along.

    Venice grew out of small islands in saltwater lakes when some Italians escaped(逃跑)from a war more than 1,500 years ago, and built homes there.

    Water makes the city special, but it is also a big problem.

    Once, people used too much underground water. This made the city get lower, little by little. Now the city has gone down by 23 centimetres.

    Another problem is the rising seawater. The temperature has risen over the years. This has made arctic(北极的)ice melt.

    Scientists are trying different ways to stop the city from getting even lower.

    In America, some teenagers are interested in charity. They are willing to help others. Some teenagers even set up their own charity group. Shreya Papneja is one of them.

    Shreya Papneja is 13 years old. She started a charity group called Children's Health Awareness Program in Schools. Her charity group helps kids make healthy choices and tries to stop childhood obesity(肥胖).

    A doctor once told Papneja that more than one-third of children were overweight. She did a lot of research about it. Then she made a website to teach other children about exercise and healthy eating.

    She does a lot of things for her charity group when she is free. For example, she often organizes different activities at schools around her hometown.

    I know how hard it is to make a change, but I won't give up. At least I've changed a lot. Now I eat more healthy food instead of junk food," she said to a reporter.
