5.When Jack Homer is on the job,he lives in a tent.And he hunts from sunup to sundown across the plains of Montana.
"When I'm walking around the field looking for things,I run across snakes and,occasionally,grizzly bears,"Homer says.Horner is curator of paleontology (古生物學(xué))at the Museum of the Rockies in Bozeman,Montana.(71)D
Horner finds dinosaurs in the forms of fossilized bones.He uses these bones to help scientists understand how dinosaurs lived when they ruled the earth more than 65million years ago.
(72)C To locate a good spot to hunt for them.Horner uses a geologic map"I just look up the geologic age in which dinosaurs lived,"Horner says."I look on the map to see where that rock is exposed at the surface of the ground.And then I walk I around in those areas looking for bones."(73)B They dig out the bones using tools as big as jackhammers and as small as dental picks.Then they take the bones,wrapped in plaster casts for protection,back to the museum.
Horner is so good at finding and interpreting dinosaur bones that he is considered one of the leading paleontologists in the world.In 1978,he discovered the first nest of baby dinosaurs ever found.The nest was the first evidence that Dinosaurs cared for their young.(74)G Paleontologists got to know how dinosaurs laid their eggs and how they took care of their young.Paleontologists learned all sorts of things that people hadn't even guessed at before.
Horner says some people think his job very romantic and assume that he is a daring adventurer.(75)A"Getting the stuff out of the ground when it's snowing or blowing 40miles an hour can be miserable.Of course,it can get to be 110degrees with no shade too."But Horner also admits that he wouldn't be a dinosaur hunter if it were not exciting.

A.Actually,the job is mostly hard work.
B.Later,trained workers go to the"dig"site.
C.Dinosaur bones are usually buried in rock.
D.Or,to put it another way,he is a dinosaur hunter.
E.I construct the evidence the same way as a detective does.
F.He also takes a lot of notes and photographs to record what he has found.
G.Horner's discovery put paleontologists into a new area of understanding dinosaur behavior.

15."My work is done."Those words were some of the last penned by George Eastman.He included them in his suicide note.They mark an ignoble end to a noble life,the leave taking of a truly great man.The same words could now be said for the company he left behind.Actually,the Eastman Kodak Company is through.It has been mismanaged financially,technologically and competitively.For 20 years,its leaders have foolishly spent down the patrimony of a century's prosperity.One of America's bedrock brands is about to disappear,the Kodak moment has passed.
But George Eastman is not how he died,and the Eastman Kodak Company is not how it is being killed.Though the ends be needless and premature,they must not be allowed to overshadow the greatness that came before.Few companies have done so much good for so many people,or defined and lifted so profoundly the spirit of a nation and perhaps the world.It is impossible to understand the 20th Century without recognizing the role of the Eastman Kodak Company.
Kodak served mankind through entertainment,science,national defense and the stockpiling of family memories.Kodak took us to the top of Mount Suribachi and to the Sea of Tranquility.It introduced us to the merry old Land of Oz and to stars from Charlie Chaplin to John Wayne,and Elizabeth Taylor to Tom Hanks.It showed us the shot that killed President Kennedy,and his brother bleeding out on a kitchen floor,and a fallen Martin Luther King Jr.on the hard balcony of a Memphis motel.When that sailor kissed the nurse,and when the spy planes saw missiles in Cuba,Kodak was the eyes of a nation.From the deck of the Missouri to the grandeur of Monument Valley,Kodak took us there.Virtually every significant image of the 20th Century is a gift to posterity from the Eastman Kodak Company.
In an era of easy digital photography,when we can take a picture of anything at any time,we cannot imagine what life was like before George Eastman brought photography to people.Yes,there were photographers,and for relatively large sums of money they would take stilted pictures in studios and formal settings.But most people couldn't afford photographs,and so all they had to remember distant loved ones,or earlier times of their lives,was memory.Children could not know what their parents had looked like as young people,grandparents far away might never learn what their grandchildren looked like.Eastman Kodak allowed memory to move from the uncertainty of recollection,to the permanence of a photograph.But it wasn't just people whose features were savable; it was events,the sacred and precious times that families cherish.The Kodak moment,was humanity's moment.
And it wasn't just people whose features were savable; it was events,the precious times that familes cherish.Kodak let the fleeting moments of birthdays and weddings,picnics and parties,be preserved and saved.It allowed for the creation of the most egalitarian art form.Lovers could take one another's pictures,children were photographed walking out the door on the first day of school,the person releasing the shutterdecided what was worth recording,and hundreds of millions of such decisions were made.And for centuries to come,those long dead will smile and dance and communicate to their unborn progeny.Family history will be not only names on paper,but smiles on faces.
The cash flow not just provided thousands of people with job,but also allowed the company's founder to engage in some of the most generous philanthropy in America's history.Not just in Kodak's home city of Rochester,New York,but in Tuskegee and London,and at the Massachusetts Institute of Technology.He bankrolled two historically black colleges,fixed the teeth of Europe's poor,and quietly did good wherever he could.While doing good,Kodak did very well.Over all the years,all the Kodakers over all the years are essential parts of that monumental legacy.They prospered a great company,but they-with that company-blessed the world.
That is what we should remember about the Eastman Kodak Company.
Like its founder,we should remember how it lived,not how it died.
History will forget the small men who have scuttled this company.
But history will never forget Kodak.

55.According to the passage,which of the following is to blame for the fall of Kodak?B
    A.The invention of easy digital photography

    B.photos were very expensive and mostly taken indoors
    C.painting was the only way for people to keep a record of their ancestors.

60.Which do you think is the best title for the passage?C

13.Autumn blues?Let the sunshine in.
Falling leaves,withering flowers,cold winds,faint sunshine.(71)FSpirits can be low.
People who suffer from"the autumn blues"often are extremely exhausted,lack energy,need more sleep,feel increased appetite and gain weight.
"The exact cause of this condition,often called seasonal depression or seasonal affective disorder (SAD),is not known yet,"says Chen Jue,associate professor at Shanghai Mental Health Center."But recent studies indicate that weather change is influential and strongly suggest that this condition is caused by changes in the availability of sunlight."
One theory is that with decreased exposure to sunlight,the biological clock that regulates mood,sleep,and hormones is delayed,running more slowly in winter.(72)A.Another theory is that brain chemicals that transmit information between nerves may be altered (改變)in individuals with SAD.It is believed that exposure to light can correct these imbalances.
"(73)C Remember,spring always lives in your heart,"Chen says.
Here are some tips to deed with autumn depression.
•Go outdoors and get some sunlight.Move around.Fresh air and exercise improve the respiratory(呼吸)system and blood circulation and regulate the nervous system.Thus,exercise is calming and relieves one's mood.
•Relax at work.Stretch,breathe deeply.Take a tea break.Think of your next vacation.
•(74)_E Chocolate and sugar raise the spirits.
•Look at bright colors,such as red and orange.Color therapy improves mood.
•Listen to your favorite music.You can dance to it,or just lie on a cozy couch,reading a novel.
•(75)BBlooming plants are cheering.
•Call friends or family when you feel lonely or depressed.Recall some happy memories.

A.Exposure to light may reset the biological clock
B.Decorate your room and work space with flowers.
C.It is a sad season,but you can try to make it happy.
D.That is the way you can use to lighten yourself.
E.Keep a chocolate bar in your pocket.
F.For many people late autumn can be a season of gloom and depression (抑郁).
G.Autumn always gives us a beautiful scene.
