15.Four to one to the computer.That was the score.AlphaGo,a program developed by Google's London-based artificial intelligence (AI) team Deep-Mind,has just beaten a human at a really complicated game.The field of honor is a Go(围棋) board in Seoul (首尔),South Korea.Lee Sedol (李世石),a South Korean,is a world Go champion and is considered the game's most outstanding player.But he was defeated by AlphaGo.
The contest has drawn tens of thousands of online spectators who have followed the matches live on the Internet.Videos of the competition have received more than four million views since the contest began on March 9.The five-game contest took a week in all.While at a pre-match press conference,Lee said he was confident he would win five to nil (零分) or,at least,four to one,he defeated AlphaGo only once in the fourth game.
"When I look back on the three games,even if I were to go back and redo the first game,I think I would not be able to win because I misjudged AlphaGo,"Lee said at a post-game press conference on March12,following his third straight defeat.Go,which originated in China thousands of years ago,is played on a 19x 19board with black and white stones (棋子).The board's size means the number of possible moves is greater than the number of atoms in the observable universe.Go is said to be the only game that truly balances the left and right sides of the brain.According to Demis Hassabis,the leading founder of Deep Mind,Go poses a more difficult programming challenge than chess.AlphaGo's success marked the most significant milestone ever in AI.
Yet AlphaGo is only going to get smarter as it gathers more data from which it learns.Asked whether there was a ceiling to its abilities,Hassabis said he did not know."If there is,we haven't found it yet."

25.Which of the following is TRUE about Go?C
A.Go is a game dating back to millions of years ago in China.
B.Go is played on a 19x 19board with black and red stones.
C.The possible moves of Go is beyond our imagination.
D.Go is the only game that will do good to your brain.
26.The contest between AlphaGo and Lee SedolD.
A.ended up with five to nil
B.lasted more than a week
C.aroused people's love to the game of Go
D.drew many people's attention and enthusiasm
27.From the passage we know thatB.
A.Go is a game that human can't play well
B.AlphaGo marks a milestone in AI
C.Lee Sedol lacks the courage to win AlphaGo
D.AlphaGo will take the place of Go's most outstanding player
28.What Demis Hassabis said meansB.
A.it's not difficult to develop the program of Go
B.there is no limit to develop the intelligence of AlphaGo
C.AlphaGo could collect more information on its own
D.the designers of AlphaGo is not wise enough to update AlphaGo.
14.Early one morning,more than a hundred years ago,an American inventor called Elias Howe finally fell asleep.He had been working all night on the design of a sewing machine but he had run into a very difficult problem:It seemed impossible to get the thread to run around the needle without any problems.
Though he was tired,Howe slept badly.He turned and turned.Then he had a dream.He dreamt that he had been caught by terrible savages whose king wanted to kill him and eat him unless he could build a perfect sewing machine.When he tried to do so,Howe ran into the same problem as before.The thread kept getting caught around the needle.The king flew into the cage and ordered his soldiers to kill Howe.They came up towards him with their spears raised.But suddenly the inventor noticed something.There was a hole in the tip of each spear.The inventor awoke from the dream,realizing that he had just found the answer to the problem.Instead of trying to get the thread to run around the needle,he should make it run through a small hole in the center of the needle.This was the simple idea that finally made Howe design and build the first really practised sewing machine.
Elias Howe was not the only one in finding the answer to his problem in this way.Thomas Edison,the inventor of the electric light,said his best ideas came into him in dreams.So did the great physicist Albert Einstein.Charlotte Bronte also drew in her dreams in writing Jane Eyre.
To know the value of dreams,you have to understand what happens when you are asleep.Even then,a part of your mind is still working.This unconscious(无意识的),but still active part understands your experiences and goes to work on the problems you have had during the day.It stores all sorts of information that you may have forgotten or never have really noticed.It is only when you fall asleep that this part of the brain can send messages to the part you use when you are awake.However,the unconscious part acts in a special way.It uses strange images which the conscious part may not understand at first.This is why dreams are sometimes called"secret messages to us".

21.The problem Howe was trying to solve wasD.
A.what kind of thread to use
B.how to design a needle which would not break
C.where to put the needle
D.how to stop the thread from getting caught around the needle
22.Thomas Edison is spoken of becauseB.
A.he also tried to invent a sewing machine 
B.he got some of his ideas from dreams
C.he was one of Howe's best friends        
D.he also had difficulty in falling asleep
23.Dreams are sometimes called"secret messages to ourselves"becauseA.
A.strange images are used to communicate ideas
B.images which have no meaning are used
C.we can never understand the real meaning
D.only specially trained people can understand them.
13.My teacher,Mr.August J.Bachmann,was the most influential teacher I ever had.
I had gotten into trouble in his class:Another student had pushed me for fun,and I became angry and began to hit him.Mr.Bachmannthe fight,but instead of sending me to the office,he sat me down and asked a simple question:"Penna,why are you wasting your life?Why aren't you going to college?"
I didn't know anything about colleges or scholarships.No one had ever considered that a fatherless boy from the poorest neighborhood had a future.That day,instead of rushing off for lunch,he stayed and explained possible education options to me.At the end of our talk,he sent me to see a secretary who had a child at a state college.This was in 1962at Emerson High School in Union City,New Jersey.
Well,53years have passed,and what have I done with the knowledge he gave me?I gained a PhD from Fordham University when I was only 29.I taught English and social studies and then moved up the chain of command from teacher to principal(校长).
I've sat on the board for Magnet Schools of America and represented that organization at the United Nations.I've won a number of great educational awards.But where would I be if a truly caring teacher had not taken the time out of his lunch period to speak to me?It was without question only his confidence in me that helped me forward.
I have repaid his kindness hundreds of times by encouraging misguided youngsters to aim higher.If I have saved any children,it is because of him.If I have been a successful educator,it is because I had a great role model in Mr.Bachmann.

11.Nearing the age of 101has not slowed down one Japanese woman.In fact,in the swimming pool-she is only getting faster.
Recently,a 100-year-old Japanese woman became the world's first centenarian to complete a 1,500-meter freestyle swimming competition in a 25-meter poo1.
Her name is Mieko Nagaoka.Ms.Nagaoka set a world record for her age group at a recent Japan Masters Swimming Association event in the western city of Matsuyama.She swam the race in 1hour,15minutes and 54seconds.
By comparison,the overall female world record holder completed the same distance in just under 15and a half minutes.But that swimmer,Katie Ledecky,is only 17years old.And Ms.Nagao.ka was not competing against her.In fact,Ms.Nagaoka was the only competitor in the 100-104year old category.Her race was not a race of speed but of endurance,or not giving up.
Breaking swimming records is nothing new to Ms.Nagaoka.So far she has broken 25records.But she began competing when she was much younger-at 88.
Ms.Nagaoka sufferred a knee injury in her 80s,so she began swimming to help her body recover.Since her first international swimming competition,she hasn't looked back,except maybe to see if her competition is catching up.
In 2002.at a masters swim meet in New Zealand,Ms.Nagaoka took the bronze medal in the 50-meter backstroke.In 2004,she won three silver medals at an Italian swim meet.
Masters swimming is a special class of competitive swimming to promote health and friendship among participants.Swimmers compete within age groups of five years.
Japan has a large number of people who live beyond 100years old.Until she passed away this month,the oldest person in the world was also from Japan.Misao Okawa was born in 1 898.She said her secrets for longevity,or long life,were good genes,regular sleep,sushi and exercise.

33.The underlined word"centenarian"refers to someone who isB.
A.from Japan          B.100or older
C.an old competitor   D.a new swimmer
34.It can be inferred from the passage thatA.
A.some people are born with longevity genes
B.people who like swimming live longer
C.the Japanese are interested in swimming
D.woman usually live much longer than men
35.Which can best explain the spirit of Ms.Nagaoka?D
A.Not to advance is to go back.
B.After a storm comes a calm.
C.The early bird catches the worm.
D.Keep on going,never give up.
10.Film director James Cameron first became interested in sea exploration when he was a little boy.His love for the ocean grew after he made the 1989undersea adventure film The Abyss and the 1997blockbuster Titanic,one of the most successful movies of all time.Following that big success,James Cameron decided to put his film career on hold to become an explorer.
In 2012,James Cameron made a journey to the deepest spot in the Mariana Trench,known as Challenger Deep.And now the great journey has been made into a documentary film,named James Cameron's Deep-sea Challenger 3D.
In James Cameron's fantasy films,such as Avatar and The Abyss,the unexplored areas are decorated in colors and full of danger.But on his dive into Challenger Deep,the reality proved far different:white,deserted and dull.
"I felt like I had gone to another planet,"Cameron said after returning from the cold and dark place in the Western Pacific Ocean,nearly 7miles below the surface."I really have a sense of being separated and realize how tiny I am down in this big,black and unexplored place."
Cameron captured(获取) the moon-like landscape of the deep sea and documented the sea creatures he observed in the ocean.
James Cameron's Deep-sea Challenger 3D tells the story of Cameron's journey.It is a film about determination,danger and the ocean's greatest depths.The movie shows a unique insight into Cameron's world when he makes his dream reality and makes history by becoming the first person to travel alone to the deepest point on the planet.
It's an exciting film and inspiring reminder that our beautiful planet still has a lot to explore.

29.When did James Cameron become interested in the ocean?A
A.When he was in his childhood.
B.After his films The Abyss and Titanic.
C.After he achieved great success in movies.
D.When he began to explore the deep sea alone.
30.What is the reality about unexplored ocean?B
A.Colorful and dangerous.
B.Boring and deserted.
C.White and attractive.
D.Small and dull.
31.What can we know about James Cameron's Deep-sea Challenger 3D?D
A.It is a film about the exploration of ocean creatures.
B.It is a story about Cameron's film-making dream.
C.It aims to attract more people to explore the deep sea.
D.It tells us about James'journey into Challenger Deep.
32.What is the best title for this passage?C
A.The great dream of a film director
B.A film director exploring deep sea
C.James Cameron and his documentary film
D.The first person to make films about the deep sea.
9.Ernest Hemingway was not only a commanding figure in 20th-century literature,but was also a pack rat.He saved even his old passports and used bullfight tickets,leaving behind one of the longest paper trails of any author.
"Ernest Hemingway:Between Two Wars,"which opens on Friday at the Morgan Library & Museum,is the first major museum exhibition devoted to Hemingway and his work.The largest and most interesting section focuses on the'20s,Hemingway's Paris years,and reveals a writer we might have been in danger of forgetting:Hemingway before he became Hemingway.
The exhibition does not fail to include pictures of the bearded,manly,Hem.He's shown posing with some kudu he has just shot in Africa and on the bridge of his beloved fishing boat,the Pilar,with Carlos Gutiérrez,the fisherman who became the model for"The Old Man and the Sea."But the first photo the viewer sees is a big blowup of a handsome,clean-shaven,19-year-old standing on crutches.This is from the summer of 1918,when Hemingway was recovering from wounds at the Red Cross hospital in Milan and trying to turn his wartime experiences into fiction.
The evidence at this exhibition suggests that,in the early days,he often wrote in pencil,mostly in cheap notebooks but sometimes on whatever paper came to hand.The first draft of the short story"Soldier's Home"was written on sheets he appeared to have snatched from a telegraph office.The impression you get is of a young writer seized by inspiration and sometimes barreling ahead without an entirely clear sense of where he is going.
F.Scott Fitzgerald (some of whose letters with Hemingway is also on view) famously urged him to cut the first two chapters of"The Sun Also Rises,"complaining about the"elephantine facetiousness"of the beginning,and Hemingway obliged,getting rid of a clunky opening that now seems almost"meta".In 1929,in a nine-page penciled critique,Fitzgerald also suggested numerous revisions for"A Farewell to Arms."Hemingway took some of these,but less graciously,and soon afterward his friendship with Fitzgerald came to an end.
The papers at the Morgan show a Hemingway who is not always sure of himself.There are running lists of stories he kept fiddling with,and there are lists and lists of possible titles,including the 45 he considered for"Farewell"and 47 different endings for the novel.
In display case after display case,you see Hemingway during his Paris years inventing and reinventing himself,discovering as he goes along just what kind of writer he wants to be.In a moving 1925 letter to his parents,who refused to read"In Our Time,"his second story collection,he writes:"You see I'm trying in all my stories to get the feeling of the actual life across-not just to describe life-or criticize it-but to actually make it alive.So that when you have read something by me you actually experience the thing.You cant do this without putting in the bad and the ugly as well as what is beautiful."
By the time the Second World War broke out,Hemingway had solidified  into the iconic figure we now remember:Papa.Even J.D.Salinger calls him this.And a blustery,cranky Hemingway appears in 1949 when aboard the Pilar he grabs an old fishing diary and begins scrawling an angry letter to Harold Ross,the editor of The New Yorker,complaining about Alfred Kazin's review of"Across the River and Into the Trees,"not,in truth,a very good book.But,Hemingway,often drinking and depressed,didn't know it,his best work was behind him by then.
66.Which of the following is closest in meaning to the underlined words"a pack rat"(para.1)?D
A.a person who doesn't waste anything             
B.a person who cannot be relied on
C.a person who likes to collect rubbish            
D.a person who enjoys collecting things
67.How many of Hemingway's works are mentioned in this passage?C
A.4             B.5                    C.6                 D.7
68.We can conclude from the Morgan show that sometimes Hemingway was a person.A  
A.unconfident but full of inspirations         
B.stubborn but full of enthusiasm about love
C.casual but full of heroism               
D.bad-tempered but full of strange habits
69.What does the writer truly mean by saying"Hemingway before he became Hemingway"?D
A.Hemingway wrote many masterpieces before he killed himself.
B.Hemingway was once a war correspondent before he became a famous writer.
C.Hemingway devoted all his strengths to writing before he won the Nobel Prize.
D.Hemingway kept exploring the world and adjusting himself before he became a
commanding figure in literature.
