1.One Sunday.Nicholas,a teenager,went skiing at Sugarloaf Mountain in Maine.In the early afternoon,when he was planning to go home.a fierce snowstorm swept into the area.Unable to see far.he accidentally turned off (使改变方向.the path.Before he knew it.Nicholas was lost.all alone!He didn't have food.water.a phone or other supplies.He was getting colder by the minute.
Nicholas had no idea where he was.He tried to calm down.He thought about all the survival shows he had watched on TV.It was time to put the tips he had learned to use.
He decided to stop skiing.There was a better chance of someone finding him if he stayed where he was.The first thing he did was to find shelter from the freezing wind and snow.If he didn't.his body temperature would get very low.which could quickly kill him.
Using his skis.Nicholas built a snow cave.He gathered a huge mass of snow and dug out a hole in the middle.Then he piled branches on top of himself.like a blanket.to stay as warm as he could.
By that evening,Nicholas was really hungry.He ate snow and drank water from a nearby stream so that his body wouldn't lose too much water.Not knowing how much longer he could last,Nicholas did the only thing he could-he huddled(蜷缩) in his cave and slept.
The next day,Nicholas went out to look for help,but he couldn't find anyone.He followed his tracks and returned to the snow cave.because without shelter.he could die that night.On Tuesday.Nicholas went out to find help.He had walked for about a mile when a volunteer searcher found him.After two days stuck in the snow.Nicholas was saved.
Nicholas might not have survived this snowstorm if he hadn't done so.He had often watched Grylls'survival show Man vs.Wild.That's where he learned the tips that saved his life.In each programme of Man vs.Wild,Grylls is abandoned in a wild area and has to find
his way out.
When Grylls heard about Nicholas'amazing deeds.he was super impressed that Nicholas had made it since he knew better than anyone how hard Nicholas had to work to stay alive.

12.Artificial intelligence:Google's AlphaGo beats Go master Lee Se-dol
A computer program has beaten a master Go player 3-0 in a best-of-five competition,in what is seen as a landmark moment for artificial intelligence (人工智能).
Google‟s AlphaGo program was playing against Lee Se-dol in Seoul,in South Korea.
Mr Lee had been confident he would win before the competition started.
"AlphaGo played consistently (稳定地) from beginning to the end while Lee,as he is only human,showed some mental weakness,"one of Lee‟s coaches,Kwon Kap-Yong,told the AFP news agency.
Mr Lee is considered as a successful Go player,having won many competitions in his career.
Go is a game of two players who take turns putting black or white stones on a 19-by-19 grid (棋格).Players win by surrounding their competitors pieces with their own.
In the first game of the series (系列赛),AlphaGo won by a very small chance-Mr Lee had led for most of the match,but AlphaGo managed to build up a strong lead in its closing stages.
After losing the second match to DeepMind,Lee Se-dol said he was"speechless"adding that the AlphaGo machine played a"nearly perfect game".
Experts said that Lee Se-dol had brought his"top game"but that AlphaGo had won"in great style".
The AlphaGo system was developed by British computer company DeepMind which was bought by Google in 2014.It has built up its special skills by studying older games and teasing out so many kinds of ways of play.And,according to DeepMind CEO Demis Hassabis,it has also spent a lot of time just playing the game.
"It played itself,millions and millions of times and each time got a little better-it learns from its mistakes,"he told the BBC before the matches started.
This good circle of continuous improvement meant the super computer went into the five-match series stronger than when it beat the European player late last year.
Does this mean artificial intelligence is now smarter than us and will kill us humans?Certainly not.AlphaGo doesn‟t care if it wins or loses.Does it mean that artificial intelligence will soon take your job?Possibly you should be more worried about that.

48.What had Lee Se-dol thought about the competition before it started?A
A.He would beat AlphaGo.
B.AlphaGo would lead the match.
C.It was hard to tell who would win.
D.AlphaGo would have some weakness.
49.What happened in the first game of the series?C
A.Mr Lee won by a very small chance.
B.AlphaGo had led for most of the match.
C.Mr Lee was beaten by AlphaGo finally.
D.AlphaGo built up a strong lead at the beginning.
50.What does the underlined phrase"teasing out"probably mean?B
A.Giving out.
B.Working out.
C.Running out.
D.Pointing out.
51.The writer may agree thatCin the future.
A.human will be killed by artificial intelligence
B.artificial intelligence will do everyt hing for human
C.people might lose jobs because of artificial intelligence
D.artificial intelligence will be much smarter than human.
