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.

“Maybe these kids are being asked to rise at the wrong time for their bodies,” says Mary Carskadon, a professor looking at problem of adolescent (青春期的)sleep at Brown’s School of Medicine.
Carskadon is trying to understand more about the effects of early school time in adolescents. And, at a more basic level, she and her team are trying to learn more about how the biological changes of adolescence affect sleep needs and patterns(方式).
Carskadon says her work suggests that adolescents may need more sleep than they did at childhood, no less, as commonly thought.
Sleep patterns change during adolescence, as any parent of an adolescent can prove. Most adolescents prefer to stay up later at night and sleep later in the morning. But it’s not just a matter of choice---their bodies are going through a change of sleep patterns.
All of this makes the transfer(迁移)from middle school to high school---which may start one hour earlier in the morning----all the more difficult, Carskadon says. With their increased need for sleep and their biological clocks set on the “sleep late, rise late” pattern, adolescents are up against difficulties when they try to be up by 5 or 6 a.m. for a 7:30 a.m. first bell. A short sleep on a desktop may be their body’s way of saying. “I need a timeout.”
小题1:Carskadon suggests that high schools should not start classes so early in the morning because _______.
| A．it is really tough for parents to enforce bedtime |
| B．it is biologically difficult for students to rise early |
| C．students work so late at night that they can’t get up early |
| D．students are so lazy that they don’t like to go to school early |
| A．turn around | B．agree with others | C．fall asleep | D．refuse to work |
| A．Adolescents depend more on their parents. |
| B．Adolescents have to choose their sleep patterns. |
| C．Adolescents sleep better than they did at childhood. |
| D．Adolescents need more sleep than they used to. |
| A．Adolescent health care. |
| B．Problems in adolescent learning. |
| C．Adolescent sleep difficulties. |
| D．Changes in adolescent sleep needs and patterns. |
Xu Hanchi, 13:
I went to a square（广场）in a local university with my classmates to do cleaning. We swept off the fallen leaves and picked up rubbish. When we finished, the ground was very clean. Though no one came up to praise us, we still felt very happy. We learned that doing good things itself could make us happy.
Zhu Lingyue, 14:
My group cleaned the teachers’ office that day. When we got there, we were surprised that the office was not as clean as we expected. How could teachers work in such an untidy（不整洁的） place? We started cleaning quickly. Teachers work really hard and may not have the time to clean their offices. It’s great that we can do something to help make them less tired.
Tom Rui, 14:
We helped clean the yard in the front of a hospital, but some patients（病人） there left us a very bad impression（印象）. They were very impolite and shouted at nurses and doctors.

For anything you’re about to send: ask yourself, “ Would I say that to the person’s face?” If the answer is no, rewrite and reread. If someone in the chat room is rude to you, you needn’t to fire back. You should either ignore(不理睬) the person, or use your chat software to block their messages. Remember to respect the beliefs and opinions of others in the chat room.
Everyone was new to the network once. Offer advice when asked by newcomers, as they may not be sure what to do or how to communicate. When someone makes a mistake, be kind about it. If you do decide to tell someone about the mistake, point it out politely. At the same time, if you find you are wrong, be sure to correct yourself and apologize to those that you have offended(冒犯). You’d better not ask others questions about their age, sex and families. Unless you know the person very well, and you are both comfortable with sharing personal information, or don’t ask such questions.
