Passage 5　　In the eyes of Edmund Daukoru, Nigeria’s oil minister and the current president of the Organisation of the Petroleum Exporting Countries (OPEC), the price of oil is “ very low “. Compared with July, when it peaked at $ 78.40 a barrel, he is right. Since then, it has fallen by almost a quarter. On September 25th, it briefly slipped below $ 60 a barrel, its lowest level in six months. The same analysts who just a few short months ago were wondering about the effect of expensive oil on the world economy are now pondering the consequences of a slump.　　That might prove premature. For one thing, Mr. Daukoru insists that OPEC will do something to stem the slide. At its last meeting, in mid-September, the group threatened to cut its output without notice if the price fell further. Saudi Arabia, for one, has been selling less oil of late. Ministers from different OPEC countries have been making different noises about whether a cut is desirable or likely, but all would be loath to see their revenues eroded by lower prices.　　The world is still consuming almost as much oil as it can pump, so any reduction in supply could send prices skywards again. Both the relative calm of this year’s hurricane season and the diminishing threat of an interruption to Iran’s oil exports seem to have contributed to the recent fall. But should clouds gather over the Atlantic, or tempers rise in the Middle East, the price could jump again.　　Moreover, the price of oil usually falls in the autumn, after the summer surge in petrol consumption has abated but before winter brings higher demand for heating oil. According to Sabine Schels, a commodity strategist at Merrill Lynch, seasonal swings in fuel prices are becoming more pronounced, thanks to a shortage of refining and storage capacity. At times of peak demand, she argues, the petrol price must rise high enough to prompt the reopening of old and inefficient refineries that would not normally be profitable. Those refineries, in turn, use up a lot more oil, pushing up its price too.　　Oil markets will not escape this cycle, Miss Schels believes, until more refineries and storage tanks are built, and more fields developed—a process that can take years. Traders in the futures market also seem to believe that the oil price will rise again. Oil for delivery- in December 2007, for example, cost $ 68 on September 27th. The price is more than $ 60 for all months until December 2011.　　Those bets could sour, however, if the American economy slows, as many suspect it is already doing. That would dent demand for oil, both from America itself and from countries that supply it with imports, such as China. Economists at HSBC, who expect a sharp American slowdown in 2007, now think Asian GDP growth will be 5.8% in 2007, against the consensus forecast of 6.3 %.　　On the other hand, cheaper oil might help to mitigate any slowdown, in several ways. It would boost firms hit by higher energy prices, such as the struggling manufacturers of gas-guzzling cars. And it will relieve the pressure on consumers, at a time when many are worried that a stalling housing market may weigh on their spending. Economists at Morgan Stanley estimate that the fall in petrol prices from over $ 3 to $ 2.50 a gallon (the average is now $ 2.42) will alone have added some $ 78 billion to American purchasing power. Consumer confidence numbers, released on September 26th, were unexpectedly strong.　　Above all, cheaper oil would ease concerns about inflation, and so reduce the need for central bankers to increase interest rates. American inflation slowed in August, thanks in part to smaller increases in the cost of energy and transport. That’s good news, except that it might simply prompt Americans to drive more.　　1. What does the author mean by “that might prove premature”? (Para. 2) Why does he say so?　　2. Paraphrase the sentence “those bets could sour, however, if the American economy slows” (Para. 6)　　3. Why cheaper oil might help to “mitigate any slowdown”?

Passage2That everyone's too busy these days is a cliché.But one specific complaint is made especially mournfully:There's never any time to read.What makes the problem thornier is that the usual time-management techniques don't seem sufficient. The web's full of articles offering tips on making time to read;Give up TVorCarry abook with you at all times.But in my experience, using such methods to free up the odd 30 minutes doesn't work. Sit down to read and the flywheel of work-related thoughts keeps spinning-or else you' re so exhausted that a challenging book's the last thing you need. The modern mind, Tim Parks, a novelist and critic, writes,is overwhelmingly inclined toward communication.. It is not simply that one is interrupted; it is that one is actually inclined to interruption.Deep reading requires not just time, but a special kind of time which can't be obtained merely by becoming more efficient.In fact,becoming more efficientis part of the problem. Thinking of time as a resource to be maximised means you approach it instrumentally, judging any given moment as well spent only in so far as it advances progress toward some goal. Immersive reading, by contrast, depends on being willing to risk inefficiency, goallessness, even time-wasting. Try to slot it in as a to-do list item and you' ll manage only goal-focused reading-useful, sometimes but not the most fulfilling kind.The future comes at us like empty bottles along an unstoppable and nearly infinite conveyor belt,writes Gary Eberle in his book Sacred Time, and we feel a pressure to fill these different-sized bottles(days, hours, minutes) as they pass, for if they get by without being filled, we will have wasted them.No mind-set could be worse for losing yourself in a book.So what does work? Perhaps surprisingly, scheduling regular times for reading. You'd think this might fuel the efficiency mind-set, but in fact, Eberle notes, such ritualistic behavior helps us step outside time's flowintosoul time. You could limit distractions by reading only physical books, or on single-purpose e-readers.Carry a book with you at all timescan actually work, too-providing you dip in often enough, so that reading becomes the default state from which you temporarily surface to take care of business, before dropping back down. On a really good day, it no longer feels as if you' remaking time to read, but just reading, and making time for everything else.Carry a book with you at all timescan work if_______.
