In its latest economic health check, the Washington-based Bank said tougher economic policies and the jump in commodity prices would slow the pace of world growth this year before a pick-up in activity in 2012.
The Bank predicted that global growth was on course to edge down from 3.8 percent in 2010 to 3.2 percent this year, then accelerate to 3.6 percent in 2012. It forecast that the pace of activity in high-income countries would slow from 2.7 percent in 2011 to 2.2 percent in 2012. Developing countries, which were responsible for almost half global growth in 2010, would expand by 6.3 percent this year, down from 7.3 percent in 2010.
The Bank warned that its forecasts could be over-optimistic should oil prices continue to rise. Brent crude (布伦特原油) was t

Passage Two
Questions 51 to 55 are based on the following passage.
In the past, falling oil prices have given a boost to the world economy, but recent forecasts for global growth have been toned down, even as oil prices sink lower and lower. Does that mean the link between lower oil prices and growth has weakened？
Some experts say there are still good reasons to believe cheap oil should heat up the world economy. Consumers have more money in their pockets when they’re paying less at the pump. They spend that money on other things, which stimulates the economy.
The biggest gains go to countries that import most of their oil like China, Japan, and India, But doesn’t the extra money in the pockets of those countries’ consumers mean an equal loss in oil producing countries, cancelling out the gains？ Not necessarily, says economic researcher Sara Johnson. “Many oil producers built up huge reserve funds when prices were high, so when prices fall they will draw on their reserves to support government spending and subsidies(补贴) for their consumers.”
But not all oil producers have big reserves, In Venezuela, collapsing oil prices have sent its economy into free-fall.
Economist Carl Weinberg believes the negative effects of plunging oil prices are overwhelming the positive effects of cheaper oil. The implication is a sharp decline in global trade, which has plunged partly because oil-producing nations can’t afford to import as much as they used to.
Sara Johnson acknowledges that the global economic benefit from a fall in oil prices today is likely lower than it was in the past. One reason is that more countries are big oil producers now, so the nations suffering from the price drop account for a larger share of the global economy.
Consumers, in the U.S. at least, are acting cautiously with the savings they’re getting at the gas pump, as the memory of the recent great recession is still fresh in their mind. And a number of oil-producing countries are trimming their gasoline subsidies and raising taxes, so the net savings for global consumers is not as big as the oil price plunge might suggest.
What does the author mainly discuss in the passage？
A.The reasons behind the plunge of oil prices.
B.Possible ways to stimulate the global economy.
C.The impact of cheap oil on global economic growth.
D.The effect of falling oil prices on consumer spending.

The only attention that heat exchanger should require is to ensure that the heat transfer surfaces remain substantially clean and the flow passages generally clear of obstruction. Indication that undue fouling is occurring is given by a progressive increase in the temperature difference between the two fluids, over a period of time, usually accompanied by a noticeable rise in pressure loss at a given flow.
Fouling on the sea-water side is the most usual cause of deterioration in performance. The method of cleaning the sea water-side surfaces depends on the type of heat exchanger. With shell-and-tube heat exchangers, the removal of the header covers or, m the case of the smaller heat exchangers, the headers themselves, will provide access to the tubes. Obstructions, dirt, scale etc., can then be removed, using the tools provided by the heat exchanger manufacturer. Flushing through with fresh water is recommended before a heat exchanger is returned to service. In some applications, such as piston oil cooling, progressive fouling may take place on the outside of the tubes. Most manufactures recommend a chemical flushing pr6cess to remove this in situ~ without dismantling the heat exchanger.
Plate heat exchangers may be cleaned by unclamping the stack of plates and mechanically cleaning the surface of each plate as recommended by the manufacturers. The plate seals may require replacement from time to time and here the manufacturers&39; instructions should be closely followed
By which of the following indication, can we conclude that the lube oil-sea water heat exchanger is unduly fouled？
A.the heat exchanger lube oil inlet temperature lowering
B.the heat exchanger sea-water outlet pressure rise
C.the heat exchanger temperature difference between lube oil and sea water increasing
D.the heat exchanger pressure difference between sea water inlet and outlet decreasing
