its oil, depending on a constant flow from abroad to keep cars on the road and machines running. In addition, at that time a greater percentage of homes and electrical plants were run on petroleum than today. Then, in 1973, the predominantly Arab nations of the Organization of Petroleum Exporting Countries (OPEC) resolved to stop selling oil to the United States. The move was prompted by OPEC's desire to raise prices by restricting supply and by its opposition to US support of Israel in the Arab-Israeli Yom Kippur War. The embargo (禁运) created panic in the West and caused oil prices to shoot up. Short-term oil shortage drove American consumers to wait in long lines at gas pumps. In response to the embargo, the US government enforced a series of policies designed to reduce reliance on foreign oil. These included developing additional domestic sources (such as those on Alaska's North Slope), resuming extraction at sites that had been shut down because of cost inefficiency, capping the price that domestic producers could charge for oil, and beginning to import oil from a greater diversity of nations. The government also established a stockpile (贮存) of oil as a short-term buffer (缓冲) against future shortages. Stored underground in large salt caves in Louisiana, this stockpile is called the Strategic Petroleum Reserve, and currently contains over 600 million barrels of oil, roughly equivalent to one month's supply.

Passage One
Questions 52 to 56 are based on the following passage.
\is more than a serious economic downturn. What distinguishes a depression from a harsh recession is paralyzing fear - fear of the unknown so great that it causes consumers, businesses, and investors to retreat and panic. They save up cash and desperately cut spending. They sell stocks and other assets. A shattering loss of

confidence inspires behavior that overwhelms the normal self-correcting mechanisms that usually prevent a recession from becoming deep and prolonged: a depression.
Comparing 1929 with 2007-09, Christina Romer, the head of President Obama's Council of Economic Advisers, finds the initial blow to confidence far greater now than then. True, stock prices fell a third from September to December 1929, but fewer Americans then owned stocks. Moreover, home prices barely dropped. From December 1928 to December 1929, total household wealth declined only 3%. By contrast, the loss in household wealth between December 2007 and December 2008 was 17%. Both stocks and homes, more widely held, dropped more. Thus traumatized (受到创伤) the economy might have gone into a free fall ending in depression. Indeed, it did go into free fall. Shoppers refrained from buying cars, appliances, and other big-ticket items. Spending on such \fourth. And businesses shelved investment projects.
That these huge declines didn't lead to depression mainly reflects, as Romer argues, countermeasures taken by the government. Private markets for goods, services, labor, and securities do mostly self-correct, but panic feeds on itself and disarms these stabilizing tendencies. In this situation, only government can protect the economy as a whole, because most individuals and companies are involved in the self-defeating behavior of self-protection. Government's failure to perform this role in the early 1930s transformed recession into depression. Scholars will debate which interventions this time - the Federal Reserve's support of a failing credit system, guarantees of bank debt, Obama's ''stimulus\Regardless, all these complex measures had the same psychological purpose: to reassure people that the free fall would stop and, thereby, curb the fear that would perpetuate (使持久) a free fall.
All this improved confidence. But the consumer sentiment index remains weak, and all the rebound has occurred in Americans' evaluation of future economic conditions, not the present. Unemployment (9.8%) is abysmal (糟透的) , the recovery's strength unclear. Here, too, there is an echo from the 1930s. Despite bottoming out in 1933, the Depression didn't end until World War II. Some government policies aided recovery; some hindered it. The good news today is that the bad news is not worse.

Passage Two
Questions 57 to 62 are based on the following passage.
\leaves and organic debris on the forest floor,\increasingly get rustle and crunch. That's the sound of a dying forest.\
Predictions of the collapse of the tropical rain forests have been around for years. Yet until recently the worst forecasts were almost exclusively linked to direct human activity, such as clear-cutting and burning for pastures or farms. Left alone, it was assumed, the world's rain forests would not only flourish but might even rescue us from disaster by absorbing the excess carbon dioxide and other planet-warming greenhouse gases. Now it turns out that may be wishful thinking. Some scientists believe that the rise in carbon levels means that the Amazon and other rain forests in Asia and Africa may go from being assets in the battle against rising temperatures to liabilities. Amazon plants, for instance, hold more than 100 billion metric tons of carbon, equal to 15 years of tailpipe and chimney emissions. If the collapse of the rain forests speeds up dramatically, it could eventually release 3.5-5 billion metric tons of carbon into the atmosphere each year - making forests the leading source of greenhouse gases.

Uncommonly severe droughts brought on by global climate changes have led to forest-eating wildfires from Australia to Indonesia, but nowhere more acutely than in the Amazon. Some experts say that the rain forest is already at the
.
Extreme weather and reckless development arc plotting against the rain forest in ways that scientists have never seen. Trees need more water as temperatures rise, but the prolonged droughts have robbed them of moisture, making whole forests easily cleared of trees and turned into farmland. The picture worsens with each round of El Nino, the unusually warm currents in the Pacific Ocean that drive up temperatures and invariably presage (预示) droughts and fires in the rain forest. Runaway fires pour even more carbon into the air, which increases temperatures, starting the whole vicious cycle all over again.
More than paradise lost, a perishing rain forest could trigger a domino effect - sending winds and rains kilometers off course and loading the skies with even greater levels of greenhouse gases - that will be felt far beyond the Amazon basin. In a sense, we are already getting a glimpse of what's to come. Each burning season in the Amazon, fires deliberately set by frontier settlers and developers hurl up almost half a billion metric tons of carbon a year, placing Brazil among the top five contributors to greenhouse gases in the world.
