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.

People know the danger of fires. It’s good for a family to learn how to prepare for a fire. Here are some suggestions:

Put a smoke alarm in the house. Smoke from a fire causes the alarm to go off. The alarm makes a loud sound. The sound tells everyone to leave the house at once.

Make escape (逃脱) plans. They should know all the ways out of the house. If there is a fire, everyone follows the plan to get out. Part of the plan is to check all the windows to make sure they can be opened easily.

Buy fire extinguishers (灭火器) in the house. Everyone in the family should know how to use them.

Practice for a fire. They do fire practice because they teach children about fire safety. Everyone in the family should know the following fire rules:

    ＊Don’t open a hot door! The fire can grow more quickly if you open the door.

＊Stay close to the floor! Smoke can be more dangerous than fire; the best air is near the floor because smoke rises.

＊What will you do if you hair or clothes start to burn? First, stop! Don’t run! The fire burns faster because of more air. Drop! Fall to the floor. They roll! Turning over and over will make the fire go out. Put a blanket (毯子) around you to keep air away from the fire that may still be on you.

There are many possible causes for firs. A wise family is ready all the time. If there is a fire, don’t forget to call 119 for help.
