单选题{{B}}Passage Three{{/B}} Thousands of gypsies have been trying to emigrate to Canada and Britain. They say they are fleeing persecution(迫害), but most have found they are not welcome in these countries either. Gypsies have never had a home. Europe has experienced enormous upheavals this century. Wars, revolutions, separations and elections have changed the political map of the continent countless times. And with each change, power has shifted, creating new winners and new losers. But for one group -- the gypsies -- change has always meant losing. With each upheaval, the gypsies have been left worse off than they were before. Yet they have survived to become Europe's largest minority. Moreover, they have succeeded in preserving their culture and their way of life in the face of genocide (种族灭绝), political persecution and poverty. In other cases where minorities have survived similar persecutions -- like Jews during World War Ⅱ, or blacks in South Africa -- their cause has received international support. By contrast, the gypsies' success at preserving their culture is not regarded as an achievement at all. Instead, it' s viewed as proof they are both unwilling and unable to change, and therefore irredeemable (不可救药的). Indeed, in 1993, the president of the Slovak Republic attacked their way of life and said steps should be taken to limit the extension of this socially unacceptable and mentally backward population. If such a thing had been said about any other minority, the political protest would have been enormous But, bemuse the Slovak President was referring to gypsies, there were few complaints, except from a few small organizations who try to protect gypsies' rights.

单选题Artificial hearts have long been the stuff of science fiction. In "Robocop", snazzy cardiac devices are made by Yamaha and Jensen, and in "Star Trek", Jean-Luc Picard, captain of the Enterprise, has one implanted in the year 2328. In the present day, however, their history has been more chequered. The first serious attempt to build one happened in the 1980s, when Jarvik-7, made by Robert Jarvik, a surgeon at the University of Utah, captured the world's attention. But Jarvik-7 was a complicated affair that needed to be connected' via tubes to machines outside the body. The patient could not go home, nor even turn around in bed. Various other designs have been tried since, but all were seen as temporary expedients intended to tide a patient over until the real thing became available from a human donor. That may be about to change. This week, America's Food and Drug Administration gave its approval to a new type of artificial heart made by Abiomed, a firm based near Boston. The agency granted a "humanitarian device exemption", a restricted form of approval that will allow doctors to implant the new device in people whose hearts are about to fail but who cannot, for reasons such as intolerance of the immunosuppressive drugs needed to stop rejection, receive a transplant. Such people have a life expectancy of less than a month, but a dozen similarly hopeless patients implanted with Abiomed's heart survived for about five months. Unlike Dr. Jarvik's device, this newfangled bundle of titanium and polyurethane alms to set the patient free. An electric motor revolving up to 10 000 times a minute pushes an incompressible fluid around the Abiomed heart, and that fluid, in turn, pushes the blood--first to the lungs to be oxygenated, and then around the body. Power is supplied by an electric current generated in a pack outside the body. This induces current in the motor inside the heart. All diagnostics are done remotely, using radio signals. There are no tubes or wires coming out of the patient. The charger is usually plugged into the mains, but if armed with a battery it can be carried around for hours in a vest or backpack, thus allowing the patient to roam freely. Most strikingly, the device's internal battery can last half an hour before it needs recharging. That allows someone time to take a shower or even go for a quick swim without having to wear the charger. Abiomed's chairman, Michael Minogue, does not claim that his firm's product will displace human transplants. Even so, the firm has big ambitions. It is already developing a new version that will be 30% smaller (meaning more women can use it) and will last for five years. That should be ready by 2008--320 years earlier than the writers of "Star Trek" predicted.

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.
