Imagine one day the water taps (水龙头) in your house stop running. You have to pay a lot of money to buy water from shops. And still there isn’t enough water for everyone. Your mother has to save the family’s shower water to use for washing clothes. Would you be able to stand that kind of life?

Probably not. But that is what kids in Yemen (也门) are experiencing (经历). According to a report, the capital, Sana, will run out of drinking water as early as 2025.

Because of the water shortage (短缺), the Yemen government often cuts the water supply (供应). Hannan, an 18-year-girl, tells the Teens, “In a good week we’ll have a water supply all week. But then the next week there will be water only for a day or two.”

Hannan says only rich people have enough water to use. They can buy water from the shops or from the water trucks. Private (私人的) companies own the trucks, They travel around the city every day to sell water--- at very high prices.

“ A lot of people can’t pay for it,” she says.

The government is thinking of making use of seawater. But it will cost a lot and it may not happen soon enough to help the people of Yemen.
