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.

分析 本文主要讲述了一位美国发明家埃利亚斯豪在发明缝纫机的时候遇到了一个棘手的问题,在现实中怎样也无法解决,而有一天在梦中他突然发现了这个问题的解决办法,而同样在梦中解决问题的还有爱迪生等人,引出梦对人们的价值.

解答 21.D细节理解题,由第一段最后一句可知,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.埃利亚斯要解决的问题是如何组织线绕住周围的针,故选D
22.B细节理解题,由第三段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.可知提到爱迪生是因为他和埃利亚斯一样在梦中解决过问题,故选B
23.A细节理解题,由最后一段可知This unconscious,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.梦给我们神秘的信息是因为在我们睡着的时候大脑的一部分仍然在解决我们白天遇到的问题,故选A.

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.
