单选题{{B}}Text 3{{/B}} EI Nino is the term used for the period when sea surface temperatures are above normal off the South American coast along the equatorial Pacific, sometimes called the Earth's heartbeat, and is a dramatic but mysterious climate system that periodically rages across the Pacific. EI Nino means "the little boy" or "the Christ child" in Spanish, and is so called because its warm current is felt along coastal Peru and Ecuador around Christmas. But the local warming is just part of an intricate set of changes in the ocean and atmosphere across the tropical Pacific, which covers a third of the Earth's circumference. Its intensity is such that it affects temperatures, storm tracks and rainfall around the world. Droughts in Africa and Australia, tropical storms in the Pacific, torrential rains along the Californian coast and lush greening of Peruvian deserts have all been ascribed to the whim of EI Nino. Until recently it has been returning about every three to five years. But recently it has become more frequent--for the first time on record it has returned for a fourth consecutive year--and at the same time a giant pool of unusually warm water has settled clown in the middle of the Pacific and is showing no signs of moving. Climatologists don't yet know why, though some are saying these {{U}}aberrations{{/U}} may signal a worldwide change in climate. The problem is that nobody really seems sure what causes the EI Nino to start up, and what makes some stronger than others. And this makes it particularly hard to explain why it has suddenly started behaving so differently. In the absence of EI Nino and its cold counterpart, La Nina, conditions in the tropical eastern Pacific are the opposite of those in the west: the east is cool and dry, while the west is hot and wet. In the east, it's the winds and currents that keep things cool. It works like this. Strong, steady winds, called trade winds, blowing west across the Pacific drag the surface water along with them. The varying influence of the Earth's rotation at different latitudes, known as the Coriolis effect, causes these surface winds and water to veer towards the poles, north in the northern hemisphere and south in the southern hemisphere. The surface water is replaced by colder water from deeper in the ocean in a process known as upwelling. The cold surface water in turn chills the air above it. This cold dense air cannot rise high enough for water vapor to condense into clouds. The dense air creates an area of high pressure so that the atmosphere over the equatorial eastern Pacific is essentially devoid of rainfall.

单选题You"ve now heard it so many times, you can probably repeat it in your sleep. President Obama will no doubt make the point publicly when he gets to Beijing: the Chinese need to consume more; they need—believe it or not—to become more like Americans, for the sake of the global economy. And it"s all true. But the other side of that equation is that the U. S. needs to save more. For the moment, American households actually are doing so. After the personal-savings rate dipped to zero in 2005, the shock of the economic crisis last year prompted people to snap shut their wallets. In China, the household-savings rate exceeds 20%. It is partly for policy reasons. As we"ve seen, wage earners are expected to care for not only their children but their aging parents. And there is, to date, only the flimsiest (脆弱的) of publicly-funded health care and pension systems, which increases incentives for individuals to save while they are working. But China is a society that has long esteemed personal financial prudence (谨慎). There is no chance that will change anytime soon, even if the government creates a better social safety net and successfully encourages greater consumer spending. Why does the U. S. need to learn a little frugality (节俭)? Because healthy savings rates are one of the surest indicators of a country"s long-term financial health. High savings lead, over time, to increased investment, which in turn generates productivity gains, innovation and job growth. In short, savings are the seed corn of a good economic harvest. The U. S. government thus needs to act as well. By running constant deficits, it is dis-saving, even as households save more. Peter Orszag, Obama"s Budget Director, recently called the U. S. budget deficits unsustainable and he"s right. To date, the U. S. has seemed unable to see the consequences of spending so much more than is taken in. That needs to change. And though Hu Jintao and the rest of the Chinese leaderships aren"t inclined to lecture visiting Presidents, he might gently hint that Chinese government is getting a little nervous about the value of the dollar—which has fallen 15% since March, in large part because of increasing fears that America"s debt load is becoming unmanageable. That"s what happens when you"re the world"s biggest creditor: you get to drop hints like that, which would be enough by themselves to create international economic chaos if they were ever leaked. (Every time any official in Beijing deliberates publicly about seeking an alternative to the U. S. dollar for the $2.1 trillion China holds in reserve, currency traders have a heart attack. ) If Americans saved more and spent less, consistently over time, they wouldn"t have to worry about all that.

Companies that reimburse outside childcare programs actually see less absenteeism among working parents than companies with in-house programs. B. In-house childcare programs create distractions for nonparents that can harm their productivity. C. Absenteeism is not a serious problem for companies that impose harsh penalties on employees who miss work. D. Studies have shown that employees with children are more likely than those without children to remain in the same job for more than five years. E. Potential employees generally view companies with in-house childcare programs as more desirable places to work than companies without such programs.

单选题Saudi Arabia, the oil industry's swing producer, has become its flip-flopper. In February, it persuaded OPEC to cut its total production quotas by lm barrels per day (bpd), to 23.5m, as a precaution against an oil-price crash this spring. That fear has since been replaced by its opposite. The price of West Texas crude hit $40 last week, its highest since the eve of the first Iraq war, prompting concerns that higher oil prices could sap the vigour of America's recovery and compound the frailty of Europe's. On Monday May 10th, Ali al-Naimi, Saudi Arabia's energy minister, called on OPEC to raise quotas, by at least 1.5m bpd, at its next meeting on June 3rd. Thus far, the high oil price has been largely a consequence of good things, such as a strengthening world economy, rather than a cause of bad things, such as faster inflation or slower growth. China's burgeoning economy guzzled about 6m bpd in the first quarter of this year, 15% more than a year ago, according to Goldman Sachs. Demand was also strong in the rest of Asia, excluding Japan, growing by 5.2% to 8. lm bpd. As the year progresses, the seasonal rhythms of America's drivers will dictate prices, at least of the lighter, sweeter crudes. Americans take to the roads en masse in the summer, and speculators are driving up the oil price now in anticipation of peak demand in a few months' time. Until recently, the rise in the dollar price of oil was offset outside America and China by the fall in the dollar itself. But the currency has regained some ground in recent weeks, and the oil price has continued to rise. Even so, talk of another oil-price shock is premature. The price of oil, adjusted for inflation, is only half what it was in December 1979, and the United States now uses half as much energy per dollar of output as it did in the early 1970s. But if oil cannot shock the world economy quite as it used to, it can still give it "a good kick", warns Goldman Sachs. If average oil prices for the year come in 10% higher than it forecast, it reckons CDP growth in the Group of Seven (CT) rich nations will be reduced by 0.3%, or $70 billion. The Americans are certainly taking the issue seriously. John Snow, their treasury secretary, called OPEC's February decision "regrettable", and the rise in prices since then "not helpful". Washington pays close heed to the man at the petrol pump, who has seen the average price of a gallon of unleaded petrol rise by 39 cents in the past year. And the Saudis, some mutter, pay close heed to Washington. Besides, the high oil price may have filled Saudi coffers, but it has also affronted Saudi pride. Mr. al-Naimi thinks the high price is due to fears that supply might be disrupted in the future. These fears, he says, are "unwarranted". But the hulking machinery in the Arabian desert that keeps oil flowing round the world presents an inviting target to terrorists should they tire of bombing embassies and nightclubs. On May 1st, gunmen killed six people in a Saudi office of ABB Lummus Global, an American oil contractor. Such incidents add to the risk premium factored into the oil price, a premium that the Saudis take as a vote of no confidence in their kingdom and its ability to guarantee the supply of oil in the face of terrorist threats.
