【单选题】The questions in this group are based on the content of a passage.After reading the passage, choose the best answer to each question,Answer all questions following the passage on the basis of what is stated or implied in the passage.
Forget hostile aliens.According to a forthcoming book by noted astrophysicistEgbert Larson, the intrepid humans who first attempt interstellar space travel will face far more daunting challenges before they ever meet the Little Green Men.
Larson begins with the problem of relativistic time dilation. If you travel all the way toAlphaCentauri, you’d like to come back and tell your friends about it, right It’s not too likely to happen, though. If Mr.Einstein was right about relativity--and we’re not going to say he wasn’t--then time slows down when you approach the speed of light.A、person traveling at any velocity near the speed of light will age only days for every week, month, or even year that passes on earth. Relativity does not present a problem for interstellar space travel, per se, but it does mean that interstellar civilizations or even just interstellar communications will require a mind-boggling amount of calendar juggling.
Did we mention that you’d have to travel at near the speed of light That’s because the distance between stars is so vast that even if you could travel at the speed of light--which, Larson reminds us, you can’t--it would take more than four years to reach our closest star neighbors,Alpha Proxima andAlphaCentauri, and decades or centuries to reach the other stars in our "immediate neighborhooD、"And if you tried to accelerate directly to the speed of light like they do in the movies, you’d be instantly splattered on the back of your theoretical spacecraft.Achieving anything close to light speed will require sustained accelera- tion at a level that human bodies can withstand--say, a crushing two gravities--for over a year.Better hope somebody brings some chips.
Speaking of chips, food is going to be a problem. Since it is economically, if not physically, impossible to accelerate 200 years’ worth of food to nearly the speed of light, and since you’re not likely to find any grocery stores along the way, someone will have to figure out how to make food in space. Keeping a crew alive on the way turns out to be the trickiest part of all. Once you’ve got the nearly impossible physics of space travel worked out, you still have to figure out the chemistry and biology of keeping your air and water clean and keeping your crew fed and safe from radiation and infection, and--did we mention the 200 years --you’ll probably need several generations of crew members to complete the trip.Ever been on a bus for more than 24 hours It’s not a pretty picture.
We applaud Larson for his insightful writing and his scrupulous attention to scientific detail. For those of you seeking a cold, hard look at the reality of interstellar space travel, this is a stellar reaD、But be warned: Larson doesn’t let you down gently. For those of you sincerely hoping to beam up with Scotty--and you know who you are--you might want to give this one a pass.
According to the passage, which of the following will present the most difficult challenge for humans attempting interstellar space travel
A、Achieving velocities near the speed of light
B、Withstanding the acceleration necessary for traversing interstellar distances
C、Maintaining clean air and water on a journey that could last centuries
D、Accommodating the effects of relativistic time dilation
E、Enabling the humans on board to survive during the journey

【单选题】The questions in this group are based on the content of a passage.After reading the passage, choose the best answer to each question.Answer all questions following the passage on the basis of what is stated or implied in the passage.
The collapse of the stock "bubble" of Internet-related companies in 2000-2001 has resulted in more than its fair share of analysis, hand-wringing, and finger-pointing.A、panel discussion at a recent Technology Today conference in Santa Monica produced a heated debate between two former luminaries of the dot.corn world: investment banker Pat Verhofen and Sue Mickelson, founder andCEO of Internet retailer Frizbeez.com.
Verhofen fired the opening shot by placing blame for the collapse of Internet stocks on the shoulders of Internet entrepreneurs who aggressively promoted ideas without viable business models. These entrepreneurs were both irresponsible and deceptive, Verhofen argued, to take investors’ money to fund operations that could not reasonably turn a profit, such as giving computers away for free or selling bulky objects, such as dog food or furniture, over the Internet. Many of these companies, he suggested, were little more than arrangements of smoke and mirrors designed to separate investors from their money.
Mickelson responded that Verhofen was like a fox in a henhouse blaming the rooster for all the dead chickens.Entrepreneurs cannot be blamed, she argued, for trying to make money for themselves and other people, because that is what entrepreneurs do. She also stated that you cannot know what ideas will or will not work until you try them; contemporaries of the Wright brothers said that a heavier-than-air aircraft could never work, and look at the skies today.
Mickelson instead placed the blame on the unscrupulous bankers and fund managers who hyped Internet stocks in order to cash in on fees from IPOs and trades. In contrast to entrepreneurs, these financial types actually do have a responsibility to offer only sound financial advice to their clients. If anyone should bear the blame, she argued, it should be people like Pat Verhofen.
Indigo Smith, the moderator of the panel, responded that perhaps the true fault lay with the common investors, who should not have invested in technology stocks in the first place if they lacked the knowledge to do so properly. While she expressed sympathy for those elderly investors who lost substantial portions of their retirement savings on flimsy Internet stocks, she observed that no one forced them to invest in those stocks.
Which of the following best captures the meaning of the simile attributed to Mickelson that Verhofen "was like a fox in a henhouse blaming the rooster for all the dead chickens"
A、As an entrepreneur, Mickelson understands that similes and other figures of speech can help convey complex ideas to audiences.
B、Verhofen, as an investment banker, was personally responsible for promoting businesses that he knew were not viable from a long-term perspective.
C、Foxes, unlike roosters, have no legitimate business in henhouses, and are far more likely than roosters to kill chickens.
D、As an investment banker, Verhofen was more likely to be the culprit of the crime than those he identified as responsible.
E、Entrepreneurs cannot be blamed for trying to make money for themselves and other people because that is what they do.
