     Directions: Read the following passage, Answer the questions according to the information given

in the passage.

     March 22nd every year has been the World Water Day since 1993. Everyone knows that over 70% of our planet is covered with water, but do you know that only 3% of the water is fresh and less than 1% of this fresh water is available for human use?

     Water shortage

     The World Bank reports that 80 countries now have water shortages, while 40% of the more than 2 billion people, have no access to clean water. Fresh water is such a life-or-death issue(问题) in many parts of the world that every eight seconds a child dies from drinking dirty water.

     How to save water

     Turn off the tap while you brush you teeth in the morning and before bedtime, and you can save up to 8 gallons of water! That adds up to more than 200 gallons a month, enough to fill a huge fish tank that holds 6 small sharks!

      Keep your shower under 5 minutes long. In fact, a 5-minute shower uses more water than a person living in poverty in a developing country uses in an entire day.

      Fix the leak. If your toilet has a leak, you could be wasting about 200 gallons of water every day. That would be like flushing your toilet more than 50 times for no reason!

     We each share responsibility for the sustainable management of our water resources, which means using less water at home, in the workplace, at school, on holidays, on the farm,… everyone, everywhere, every time.
