[单项选择]The dot-com collapse may have been a disaster for Wall Street, but here in Silicon Valley, it was a blessing. It was the welcome end to an abnormal condition that very nearly destroyed the area in an overabundance of success. You see, the secret to the Valley’s astounding multiple-decade boom is failure. Failure is what fuels and renews this place. Failure is the foundation for innovation.
The valley’s business ecology depends on failure the same way the tree-covered hills around us depend on fire—it wipes out the old growth and creates space for new life. The valley has always been in danger of drowning in the unwelcome waste products of success—too many people, too expensive houses, too much traffic, too little office space and too much money chasing too few startups. Failure is the safety valve, the destructive renewing force that frees up people, ideas and capital and recombines them, creating new revolutions.
Consider how the Internet revolution came to be. After half a
A. The Silicon Valley blamed its failure on the success of Wall Street.
B. The Silicon Valley is also noted for its complex ecological web.
C. The Silicon Valley takes a vain pride in its overabundant successes.
D. The Silicon Valley would benefit from the collapse in certain ways.

[简答题]
Radiation occurs from three natural sources: radioactive material in the environment, such as in soil, rock, or building materials; cosmic rays; and substances in the human body, such as radioactive potassium in bone and radioactive carbon in tissues. These natural sources account for an exposure of about 100 millirems a year for the average American.
The largest single source of man-made radiation in medical x-rays, yet most scientists agree that hazards from this source are not as great as those from weapons test fallout, since strontium-90 and carbon-14 become incorporated into the body, hence delivering radiation for an entire lifetime. (46)The issue is, however, by no means uncontroversial; indeed, the last two decades have witnessed intensified examination and dispute about the effects of low-level radiation.

[A] The impotence of creationism.
[B] Natural selection acts by competition.
[C] The role of natural selection in this colorful world
[D] The delicate hierarchy of the natural system.
[E] The agency of selection can account for more cases.
[F] No leaps in natural evolution.
As each species tends by its geometrical rate of reproduction to increase excessively in number; and as the modified descendants of each species will be enabled to increase by as much as they become more diversified in habits and structure, so as to be able to seize on many and widely different places in natural selection to preserve the most divergent offspring of any one species. Hence, during a long-continued course of modification, the slight differences characteristic of varieties of the same species, tend to be augmented into the greater differences characteristic of the species of the same genus.

[单项选择]It may turn out that the "digital divide"—one of the most fashionable political slogans of recent years—is largely fiction. As you will recall, the argument went well beyond the unsurprising notion that the rich would own more computers than the poor. The disturbing part of the theory was that society was dividing itself into groups of technology "haves" and "have-nots" and that this segregation would, in turn, worsen already large economic inequalities. It is this argument that is either untrue or wildly exaggerated.
We should always have been suspicious. After all, computers have spread quickly because they have become cheaper to buy and easier to use. Falling prices and skill requirements suggest that the digital divide would spontaneously shrink—and so it has.
Now, a new study further discredits the digital divide. The study, by economist David Card of the University of California, Berkeley, challenges the notion that computers have significantly worsened wage inequality.
A. that is responsible for economic inequalities.
B. deemed to be positive in poverty-relief.
C. that results from falling computer prices.
D. getting worse because of the Internet.

[单项选择]The title of the biography The American Civil War Fighting for the Lady could hardly be more provocative. Thomas Keneally, an Australian writer, is unapologetic. In labeling a hero of the American civil war a notorious scoundrel be switches the spotlight from the brave actions of Dan Sickles at the battle of Gettysburg to his earlier premeditated murder, of the lover of his young and pretty Italian-American wife, Teresa. It is not the murder itself that disgusts Mr Keneally but Sickles’s treatment of his wife afterwards, and how his behavior mirrored the hypocritical misogyny of 19th-century America.
The murder victim, Philip Barton Key, Teresa Sickles’s lover, came from a famous old southern family. He was the nephew of the then chief justice of the American Supreme Court and the son of the writer of the country’s national anthem. Sickles, a Tammany Hall politician in New York turned Democratic congressman in Washington, shot Key dead in 1859 at a corner of Lafayette Square, with
A. launch a surprise attack on Democratic congressman.
B. show sympathy for an abused but reputed lady, Teresa.
C. curse bitterly at the hypocrisy of notorious heroes.
D. expose the true character of a general in civil war.

[单项选择]The Tuscan town of Vinci, birthplace of Leonardo and home to a museum of his machines, should fittingly put on a show of the television-robot sculptures of Nam Jun Paik. This Korean-born American artist and the Renaissance master are kindred spirits: Leonardo saw humanistic potential in his scientific experiments, Mr Paik endeavors to harness media technology for artistic purposes. A pioneer of video art in the late 1960s, he treats television as a space for art images and as material for robots and interactive sculptures.
Mr Paik was not alone. He and fellow artists picked on the video cameras because they offered an easy way to record their performance art. Now, to mark video art’s coming of age, New York’s Museum of Modern Art is looking back at their efforts in a film series called "The First Decade". It celebrates the early days of video by screening the archives of Electronic Arts Intermix (EAI), one of the world’s leading distributors of video and new media art, founded 30
A. to introduce the topic of the technology of video art.
