问答题Did life emerge spontaneously on earth, or did it come from outer space? 10 The scientific community is sharply split on the question, and the evidence from Mars (火星) not only heats up the debate but also adds a third possibility: life-forms may have arisen on Mars first and then hitched a ride on a meteorite (陨石) to Earth—or vice versa. As Stanford University chemist Richard Zare puts it, "Who is to say that we are not all Martians?" Sounds implausible? Consider the alternatives. Sir Fred Hoyle, the distinguished British astronomer, favors an even more radical theory. The idea is that billions of years ago, the solar system was peppered by biological "seeds", which took root wherever conditions were right. That would explain how life may have arisen at roughly the same time on Earth and on Mars. 11 But it also raises awkward questions about where those seeds came from and what, or who, sent them flying through space. There is something to this theory. 12 Even scientists who reject it acknowledge that some of life"s building blocks probably had extraterrestrial (外星的) origins. Indeed, they now believe that everything from organic chemicals to amino acids (氨基酸), the constituents of proteins, was carried in by the comets, asteroids (小行星) and meteorites.

问答题Brian and Kendelle Glynn, both 32, have been married seven years. Brian, a police officer, is the saver in the family. 1. Kendelle, a computer programmer, feels frustrated when she passes up the chance to buy things she feels she deserves. Many couples would be happier if they could agree on money. "It's the No. 1 problem that couples fight about," says Howard Markman, director of the Center for Marital and Family Studies at the University of Denver in the U. S. and co-author of Fighting for Your Marriage. 2. Talking about money is easier if spouses agree on priorities—the need to pay off debts, a plan to retire in ten years, a vacation to Maldives. But agreeing on financial priorities is sometimes difficult because money hahits are acquired over a lifetime and aren't easily changed. "A person's attitude toward money is almost a personality trait," says Marcia Lasswell, president of the American Association for Marriage and Family Therapy. Blame your in-laws if you want, but unless you believe a suitcase is a negotiating tool, you and your spouse need to allow for each other's financial traits. For example, Brian and Kendelle Glynn are working hard at compromise. 3. On an upcoming beach vacation they will stay in a condominium (公寓), as Kendelle wanted, instead of taking the less expensive motel room Brian had in mind. "A couple of years ago I would have said, ' No, it's too much, ' " Brian explains. And Kendelle doesn't expect to win every battle. "Next time, I have to remember that he gave in on this. /

问答题The huge earthquake that hit off the coast of northeastern Miyagi prefecture earlier this year was a harsh reminder of the more elemental dangers that can threaten economic activity on the crowded and seismically vulnerable Japanese archipelago. Weighing the full implications of the natural disaster will take time. Yet the earthquake at the very least throws a huge question mark over an economic recovery, that economists had hoped would gather steam in 2011 after stalling in the last three months of 2010. Although the areas worst hit are far less economically significant than the coastal industry zones, which suffered widespread stoppages alter the 1995 Kobe earthquake, the disaster could heighten recent uncertainty among consumers and investors about the prospects for Japan's continued recovery from its worst postwar recession. Learning from the lessons of the devastating disaster in 1995, the government and insurance companies have been actively encouraging even smaller companies to draw up detailed "business continuity plans" intended to minimize losses and aid quick recoveries. In the longer terms, the earthquake is certain to force heavy spending on construction and public works in the affected region. The terrifying footage of tsunami carrying away whole buildings makes it clear that dealing with the damage will require huge effort and heavy investment.

问答题Questions 7 to 10 are based on the several stanzas from Edgar Allen Poe"s poem The Raven.The Raven Once upon a midnight dreary, while I pondered weak and weary,Over many a quaint and curious volume of forgotten lore—While I nodded, nearly napping, suddenly there came a tapping,As of some one gently rapping, rapping at my chamber door—" Tis some visitor," I muttered, " tapping at my chamber door—Only this and nothing more.Ah, distinctly I remember it was in the bleak December;And each separate dying ember wrought its ghost upon the floor.Eagerly I wished the morrow; —vainly I had sought to borrowFrom my books surcease of sorrow—sorrow for the lost Lenore—For the rare and radiant maiden whom the angels named Lenore—Nameless here for evermore.And the silken sad uncertain rustling of each purple curtainThrilled me—filled me with fantastic terrors never felt before;So that now, to still the beating of my heart, I stood repeating"Tis some visitor entreating entrance at my chamber door—Some late visitor entreating entrance at my chamber door—This it is, and nothing more. "Presently my soul grew stronger; hesitating then no longer,"Sir, " said I, "or Madam, truly your forgiveness I implore;But the fact is I was napping, and so gently you came rapping,And so faintly you came tapping, tapping at my chamber door,That I scarce was sure I heard you"—here I opened wide the door—Darkness there, and nothing more.Deep into that darkness peering, long I stood there wondering, fearing,Doubting, dreaming dreams no mortal ever dared to dream before;But the silence was unbroken, and the darkness gave no token,And the only word there spoken was the whispered word, "Lenore?"This I whispered, and an echo murmured back the word, " Lenore!"Merely this and nothing more.

问答题但是，科学成就既在智力方面让人兴奋又能投入实际应用，它取决于科学自我修正的特征。一定有办法证明任何正确的观点，也一定有办法重复正确的实验。科学家的人格或信念并不重要，至关重要的是论据是否能证实他们的论点。权威人士的论点并不重要，因为许多权威人士频频出错。我希望看到学校和媒体传播这些行之有效的科学思维模式。当然，看到它们被引入政界更让人惊喜。众所周知，新论据或新论点呈现在科学家的面前时，他们会公开并彻底改变他们的观点，可我想不起有哪位政客同样表示要开诚布公地改变其观点。

问答题The question before us is no longer the nature of the challenge—the question is our capacity to meet it. For while the reality of climate change is not in doubt, I have to be honest, as the world watches us today, I think our ability to take collective action is in doubt right now and it hangs in the balance. I believe we can act boldly, and decisively, in the face of a common threat. That"s why I come here today—not to talk, but to act. Now, as the world"s largest economy and as the world"s second largest emitter, America bears our responsibility to address climate change, and we intend to meet that responsibility. That"s why we"ve renewed our leadership within international climate negotiations. That"s why we"ve worked with other nations to phase out fossil fuel subsidies. That"s why we"ve taken bold action at home—by making historic investments in renewable energy; by putting our people to work increasing efficiency in our homes and buildings; and by pursuing comprehensive legislation to transform to a clean energy economy. These mitigation actions are ambitious, and we are taking them not simply to meet global responsibilities. We are convinced that changing the way that we produce and use energy is essential to America"s economic future—that it will create millions of new jobs, power new industries, keep us competitive, and spark new innovation.

问答题What a lark! What a Plunge! For so it had always seemed to her, when, with little squeak of the hinges, which she could hear now, she had burst open the French windows and plunged at Bour-ton into the open air. How fresh, how calm, stiller than this of course, the air was in the early morning; like the flap of a wave; the kiss of a wave; chill and sharp and yet(for a girl of eighteen as she then was)solemn, feeling as she did, standing there at the open window, that something awful was about to happen; looking at the flowers; at the trees with the smoke winding off them and the rooks rising, falling; standing and looking until Peter Wash said, " Musing among the vegetables?"—was that it—"I prefer men to cauliflowers"—was that it?
