| 第4题：For my proposed journey, the first priority was clearly to start learningArabiC、I have never been a linguist. Though I had traveled widely as a journalist, I had never managed to pick up more than a smattering of phrases in any tongue other than French, and even my French, was laborious for want of lengthy practice. The prospect of tackling one of the notoriously difficult languages at the age of forty, and trying to speak it well, both deterred and excited me. It was perhaps expecting a little too much of a curiously unreceptive part of myself, yet the possibility that I might gain access to a completely alien culture and tradition by this means was enormously pleasing. I enrolled as a pupil in a small school in the center of the city. It was run by a MrBeheit, of dapper appearance and explosive temperament, who assured me that after three months of his special treatment I would speakArabic fluently. Whereupon he drew from his desk a postcard which an old pupil had sent him from somewhere in the MiddleEast, expressing great gratitude and reporting the astonishment of localArabs that he could converse with them like a native. It was written inEnglish. MrBeheit himself spent most of his time coaching businessmen in French, and through the thin, partitioned walls of his school one could hear him bellowing in exasperation at some confused entrepreneur: "Non, M. Jones. Jane suis pas francais. Pas, Pas, Pas!" (No Mr. Jones, I’m NOT French, I’m not, not, NOT!). I was gratified that my own tutor, whose name wasAhmed, was infinitely softer and less public in approach. For a couple of hours every morning we would face each other across a small table, while we discussed in meticulous detail the colour scheme of the tiny cubicle, the events in the street below and, once a week, the hair-raising progress of a window-cleaner across the wall of the building opposite. In between, hearing in mind the particular interest I had in acquiringArabic, I would inquire the way to some imaginary oasis, anxiously demand fodder and water for my camels, wonder politely whether the sheikh was prepared to grant me audience now. It was all hard going. I frequently despaired of ever becoming anything like a fluent speaker, thoughAhmed assured me that my pronunciation was above average for a Westemer. This, I suspected, was partly flattery, for there are a couple ofArabic sounds which not even a gift for mimicry allowed me to grasp for ages. There were, moreover, vast distinctions of meaning conveyed by subtle sound shifts rarely employed inEnglish.And for me the problem was increased by the need to assimilate a vocabulary, that would vary from place to place across five essentiallyArabic-speaking countries that practiced vernaculars of their own: so that the word for "people", for instance, might be nais, sah ’ab or sooken. Each day I was mentally exhausted by the strain of a morning in school, followed by an afternoon struggling at home with a tape recorder. Yet there was relief in the most elementary forms of understanding and progress. When merely got the drift of a torrent whichAhmed had just released, I was childishly elateD、When I managed to roll a complete sentence off my tongue without apparently thinking what I was saying, and it came out right, I beamed like an idiot.And the enjoyment of reading and writing the flowingArabic script was something that did not leave me once I had mastered it.By the end of June, no-one could have described me as anything like a fluent speaker ofArabiC、I was approximately in the position of a fifteen-year old who, equipped with a modicum of schoolroom French, nervously awaits his first trip to Paris.But this was something I could reprove upon in my own time. I bade farewell to MrBeheit, still struggling to drive the French negative into the still confused mind of Mr Jones. It is known from’ the passage that the writer______. A、had a good com |

| 第6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, mostAmericans had accepted the fundamental promises of contemporary economics. These were: First, we know enough to prevent another GreatDepression; 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, whenAmerica 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 anotherDepression.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. Were they more open-minded about economic calamities, people would [A] take care not to trigger them in the first place. [B] become more cautious in making purchase decisions. [C] become less hesitant in economic activities. [D] feel more protected from unforeseeable dangers. |
