题目内容

If you have a bottle of water recycled(再利用) from urine(尿), would you drink it? Astronauts at the ISS may soon do so.

NASA(美国航空航天局) said it would use a high-tech machine to recycle wastewater at the ISS. The machine will recycle water for washing hands, shower water, water for brushing teeth and even urine to make drinking water. It will save millions of dollars each year.

At present, each ISS astronaut uses about 4.4 liters(升) of water every day. It costs about 24 million dollars a year to send water up to the ISS. A liter of water costs about $ 11,000.

The machine will be sent to the ISS later. NASA hopes it will recycle about 93% of all the water used on the station.

Will the water be clean? Different chemicals will be put in the wastewater. The water will be heated to 130℃ to kill bacteria(细菌). Scientists say that the recycled water is thousands of times better than the water from a city tap.
