[不定项选择题]共用题干 Even Intelligent People Can Fail

1 The striking thing about the innovators who succeeded in making our modern world is
how often they failed.Turn on a light,take a photograph,watch TV,search the Web,jet
across the Pacific Ocean, talk on a celiphone(手机).The innovators who left us these
things had to find the way to success through a maze(错综复杂)of wrong turns.
2 We have just celebrated the 125th anniversary of American innovator Thomas Edison's
success in heating a thin line to white-hot heat for 14 hours in his lab in New Jersey,
U.S.He did that on October 22,1879,and followed up a month later by keeping a thread of
common cardboard alight(点亮着的)in an airless space for 45 hours.Three years later
he went on to light up half a square mile of downtown Manhattan,even though only one of
the six power plants in his design worked when he turned it on,on September 4,1882.
3 "Many of life's failures,"the supreme innovator said,"are people who did not realize
how close they were to success when they gave up."Before that magical moment in
October 1879,Edison had worked out no fewer than 3,000 theories about electric light,but
in only two cases did his experiments work.
4 No one likes failure,but the smart innovators learn from it.Mark Gumz,the head
of the camera maker Olympus America Inc,attributes some of the company's
successes in technology to understanding failure.His popular phrase is:"You only fail
when you quit."
5 Over two centuries,the most common quality of the innovators has been persistence.
That is another way of saying they had the emotional ability to keep up what they were
doing.Walt Disney,the founder of Disneyland,was so broke after a succession of
financial failures that he was left shoeless in his office because he could not afford the U.S.
$1.50 to get his shoes from the repair shop.Pioneering car maker Henry Ford failed with
one company and was forced out of another before he developed the Model T car.
6 Failure is harder to bear in today's open,accelerated world.Hardly any innovation
works the first time.But an impatient society and the media want instant success.When
American music and movie master David Geffen had a difficult time,a critic said nastily that
the only difference between Geffen Records(Geffen's company)and the Titanic(the ship
that went down)was that the Titanic had better music.Actually,it wasn't.After four years
of losses, Geffen had so many hits(成功的作品)he could afford a ship as big as the
Titanic all to himself. The media demand that_________.
A.he developed 3,000 theories
B.he couldn't afford to buy a pair of shoes
C.he found himself an unsuccessful man
D.they quitted
E.an innovation should work immediately
F.failure is the mother of success

Text 3
Just outside the northern Italian town of Bra, there rises a church tower with a clock that is a half hour slow. In Bra, that’s close enough to being tight on time. Though not far from the industrial city of Turin, Bra smells of roses, and leisure is the law. It is both the home of an international movement that promotes "slow food" (the opposite of American fast food) and one of 31 Italian municipalities that have joined a sister cause, the "slow cities." These cities have declared themselves paradises from the accelerating pace of life in the global economy. In Bra, population 27,866, the town fathers have declared that all small food shops be closed every Thursday and Sunday. They forbid cars in the town square.
