Mars(火星)appears to be flowing with small streams of salty water,at least in the summer,scientists reported Monday."It suggests that it would be possible for there to be life today on Mars," NASA's science mission chief,John Grunsfeld,said at a news conference on September 28,2015.

The streams are about 12 to 15 feet wide and 300 feet or more long,scientists said."What we're dealing with is wet soil.Thin layers of wet soil,not standing water," said Aifred McEwen of the University of Arizona at Tueson,the principal scientist for the Mars Reconnaissance Orbiter's high-resolution imaging experiment.

Because liquid water is extremely necessary to life,the findings could have major possible effects for the possibility of Martian life.The researchers said further exploration is needed to determine whether microscopic life exists on the planet.

The presence of liquid water could also make life easier for astronauts visiting or living on Mars.Water could be used for drinking and for creating oxygen and rocket fuel.NASA's goal is to send humans there in the 2030s.

The evidence of flowing water consists largely of dark,narrow streaks(条痕)on the surface that tend to appear and grow during the warmest Martian months and fade the rest of the year.

Mars is extremely cold even in summer,and the streaks are in places where the temperature is as low as minus 10 degrees Fahrenheit.But salt can lower the freezing point of water and melt ice.

The source of the water is a mystery(神秘的事物).Scientists noted it could be melting ice.It could be an underground aquifer(砂石含水层),which is rock or sand that can hold water.It is possibly water vapor from the thin Martian atmosphere,or it may be a combination Michael Meyer,lead scientist for NASA's Mars exploration program, said the only definitive way for now to determine whether there's life on Mars is to collect rocks and soil for analysis on Earth-something a U.S.lander set for lift-off in 2020 will do.

8.Several years ago,when I worked in Los Angeles,I met one l0-year-old boy who wanted to study judo despite the fact that he had lost his left arm in a disastrous car accident.
The boy began lessons with an old Japanese judo master.The boy was doing well,so he couldn't understand why,after three months of training,the master had taught him only one move.
"Master,"the boy finally said,"Shouldn't I be learning more moves?"
"This is the only move you know,but this is the only move you'll ever need to know,"the master replied.
Not quite understanding,but believing in his master,the boy kept training.
Several months later,the master took the boy to his first tournament.Surprising himself,the boy easily won his first two matches.The third match proved to be more difficult,but after some time,his opponent (对手) became impatient and charged; the boy quickly and cleverly used his one move to win the match.Still amazed by his success,the boy was now in the finals.
This time,his opponent was bigger,stronger,and more experienced.For a while,the boy appeared to be beaten.Concerned that the boy might get hurt,the referee called a time-out.He was about to stop the match when the master interrupted.
"No,"the master insisted,"Let him continue."
Soon after the match continued,his opponent made an obvious mistake:he dropped his guard.Instantly,the boy used his move to hit him to the ground.The boy had won the match and the tournament.He was the champion.
On the way home,the boy and the master reviewed every move in each and every match.Then the boy gathered the courage to ask what was really on his mind.
"Master,how did i win the tournament with only one move?"
"You won for two reasons,"the master answered."First,"you've almost mastered one of the most difficult throws in all of judo.And second; the only known defense for that move is for your opponent to grasp your left arm."

9."Don't you have any toys you want to share?"I asked my son during our church's Christmas toy drive."What about all those things in your closet you haven't used in years?"
"I don't have anything,"he said."We're so poor."
We're only"poor"because we refuse to buy him the phone he wants for Christmas,which would also require a monthly texting charge.
"You're not so poor you have nothing to give,"I found myself saying to him,a phrase my mother often used on me.
At work the next day,one of my students said,"I didn't spell your name right,"as she handed me a Christmas gift-a box of chocolates.No wonder she hadn't spelled it right-I'had only worked at the center for a couple of months,and my name is not easy to pronounce,even in English,which is this woman's second language.
I hadn't expected a gift-I worked at an adult education center,where we dealt with people who struggle economically.When I was hired,my boss told me she tries to keep snacks around the center and cooks"stone soup"once a week,where whoever can bring something in does,because"You will hear growling bellies here.They give their food to the children before they themselves eat."
And yet these people,so grateful for a second chance at getting an education,unable to sometimes even afford the gas money to come in,manage to do something for us nearly every week.Some bring in food; others do chores around the center.They help and encourage one another,and us.They give what they are able to give.
