单选题Then felt like some watcher of the skies When a new planet swims into his ken, Or like stout Cortez, when with eagle eyes He stared at the Pacific--and all his men Looked at each other with a wild surmise-- Silent, upon a peak in Darien. --Keats With these well-loved lines John Keats recognized the most important geographical event in all the world, excepting only the feat of the Admiral Columbus himself. It was the discovery by European men of a vast sheet of water covering nearly 40 per cent of the globe--the ocean later to be named Pacific by Ferdinand Magellan because of its seeming tranquility. It is too bad that Keats' beautiful lines erred in naming stout Cortez instead of the equally stout Balboa, a hero of much courage and perseverance. Too bad it was, too, for the immortal Vasco Nunez de Balboa, that communications in his day were so slow and uncertain. Had they been better he might well have avoided losing his head for his pains in bringing renown to Spain and incalculable new knowledge to the civilized world. For lose it he did, under the axe at the insance of a jealous governor.

单选题It is hard to track the blue whale, the ocean"s largest creature, which has almost been killed off by commercial whaling and is now listed as an endangered species. Attaching radio devices to it is difficult, and visual sightings are too unreliable to give real insight into its behavior. So biologists were delighted early this year when, with the help of the Navy, they were able to track a particular blue whale for 43 days, monitoring its sounds. This was possible because of the Navy"s formerly top-secret system of underwater listening devices spanning the oceans. Tracking whales is but one example of an exciting new world just opening to civilian scientists after the cold war as the Navy starts to share and partly uncover its global network of underwater listening system built over the decades to track the ships of potential enemies. Earth scientists announced at a news conference recently that they had used the system for closely monitoring a deep-sea volcanic eruption for the first time and that they plan similar studies. Other scientists have proposed to use the network for tracking ocean currents and measuring changes in ocean and global temperatures. The speed of sound in water is roughly one mile a second—slower than through land but faster than through air. What is most important, different layers of ocean water can act as channels for sounds, focusing them in the same way a stethoscope does when it carries faint noises from a patient"s chest to a doctor"s ear. This focusing is the main reason that even relatively weak sounds in the ocean, especially low-frequency ones, can often travel thousands of miles.

单选题It's a cliche—but true—that a huge obstacle to a stronger economic recovery is the lack of confidence in a strong recovery. If consumers and businesses were more confident, they would be spending, hiring and lending more freely. Instead, we're deluged with reports suggesting that, because the recession was so deep, it will take many years to regain anything like the pre-crisis prosperity. Just last week, for example, the McKinsey Global Institute released a study estimating that the country needs 21 million additional jobs by 2020 to reduce the unemployment rate to 5 percent. The study was skeptical that this would happen. Pessimism and slow growth become a vicious cycle. Battered confidence most obviously reflects the ferocity and shock of the financial collapse and the ensuing recession, including the devastating housing collapse. But there's another, less appreciated cause: disillusion with modern economics. Probably without realizing it, most Americans had accepted the fundamental promises of contemporary economics. These were: First, we know enough to prevent another Great Depression; second, although we can't prevent every recession, we know enough to ensure sustained and, for the most part, strong recoveries. These propositions, endorsed by most economists, had worked themselves into society's belief structure. Embracing them does not preclude economic disappointments, setbacks, worries or risks. But for most people most of the time, it does preclude economic calamity. People felt protected. If you stop believing them, then you act differently. You begin shielding yourself, as best you can, against circumstances and dangers that you can't foresee but that you fear are there. You become more cautious. You hesitate more before making a big commitment-buying a home or car, if you're a consumer; hiring workers, if you're an employer; starting a new business, if you're an entrepreneur; or making loans, if you're a banker. Almost everyone is hunkered down in some way. One disturbing fact from the McKinsey report is this: The number of new businesses, a traditional source of jobs, was down 23 percent in 9,010 from 2007; the level was the lowest since 1983, when America had about 75 million fewer people. Large corporations are standoffish. They have about $2 trillion of cash and securities on their balance sheets, which could be used for hiring and investing in new products. It's not that economics achieved nothing. The emergency measures thrown at the crisis in many countries exceptionally low interest rates, "stimulus" programs of extra spending and tax cuts—probably averted another Depression. But it's also true that there's now no consensus among economists as to how to strengthen the recovery. Economists suffer from what one of them calls "the pretense-of-knowledge syndrome." They act as if they understand more than they do and presume that their policies, whether of the left or right, have benefits more predictable than they actually are. It's worth remembering that the recovery's present slowdown is occurring despite measures taken to speed it up. So modern economics has been oversold, and the public is now disbelieving. The disillusion feeds stubbornly low confidence.

单选题The author made a list of Sachs's positions to show that

单选题I knew a man, a very tall, gentle man who visited prisoners in our local prison week in and week out for decades. He would write letters for them, carry messages, fetch clothing or books. But mainly he just offered himself. He did not preach (说教) to them. and didn"t look for any return on his kindness. All that mattered was that they were in trouble. Why did he spend time with them when he could have been playing golf or watching TV? "I go in ease everyone else has lost hope for them," he told me once. "I never give up." Never giving up is a trait we honor in athletes, in soldiers, in survivors of disasters, in patients recovering from severe injuries. If you struggle bravely against overwhelming opponents, you"re likely to appear on the evening news. But in less flashy, less newsworthy forms, fidelity (忠诚) to a mission or a person or an occupation shows up in countless lives all around us. It shows up in parents who will not stop loving their daughter even after she dyes her hair purple and runs off with a rock band. It shows up in couples who choose to mend their marriages instead of end in divorce. It shows up in volunteers at the hospital or library or women"s refuge or soup kitchen for the hungry. It shows up in unsung people everywhere who do their jobs well, not because the leader is watching or because they are paid lots of money but because they know their work matters.
