单项选择题 Questions 36 to 40 are based on the following passage. “Welcome to the U.S.A.! Major Credit cards accepted!” By the millions they are coming no longer the tired, the poor, the wretched mass longing for a better living. These are the wealthy. “We don’t have a budget,” says a biologist from Brazil, as she walks with two companions through New York City’s South Street. “We just use our credit cards.” The U.S. has long been one of the world’s most popular tourist destinations, but this year has been exceptional. First there was the World Cup, which drew thousands from every corner of the globe; then came the weakening of the U.S. dollar against major currencies. Now the U.S., still the world’s superpower, can also claim to be the world’s bargain basement (廉价商品部). Nobody undersells America these days on just about everything, from consumer electronics to fashion clothes to tennis rackets. Bottom retail prices-anywhere from 30% to 70% lower than those in Europe and Asia-have attracted some 47 million visitors, who are expected to leave behind $79 billion in 1994. That’s up from $74 billion the year before. True, not everyone comes just for brains. There remains an undeniable fascination in the rest of the world with all things American, nourished by Hollywood films and U.S. television series. But shopping the U.S.A. is proving irresistible. Every week thousands arrive with empty suitcases ready to be filled; some even rent an additional hotel room to hold their purchases. The buying binge (无节制) has become as important as watching Old Faithful Fountains erupt in Yellowstone Park or sunbathing on a beach in Florida. The U.S. has come at last to appreciate what other countries learned long ago: the pouring in of foreign tourists may not always be convenient, but is does put money in the bank. And with a trade deficit at about $130 billion and growing for the past 12 months, the U.S. needs all the deposits it can get. Compared with American tourists abroad, visitors to the U.S. stay longer and spend more money at each stop; an average of 12.2 night and $1624 a traveller versus the American s’ four nights and $298.第36题：From what the Brazilian biologist says, we know that tourists like her ________.A) are reluctant to carry cash with themB) simply don’t care how much they spendC) are not good at planning their expenditureD) often spend more money than they can afford

单项选择题 Passage Three:Questions 31 to 35 are based on the following passage.Just seven years ago, the Jarvik-7 artificial heart was being cheered as the model of human creativeness. The sight of Barney Clark-alive and conscious after trading his diseased heart for a metal-and-plastic pump-convinced the press, the public and many doctors that the future had arrived. It hadn’t. After monitoring production of the Jarvik-7, and reviewing its effects on the 150 or so patients (most of whom got the device as a temporary measure) the U.S. Food and Drug Administration concluded that the machine was doing more to endanger lives than to save them. Last week the agency cancelled its earlier approval, effectively banning (禁止) the device.The recall may hurt Symbion Inc., maker of the Jarvik-7, but it won’t end the request for an artificial heart. One problem with the banned model is that the tubes connecting it to an external power source created a passage for infection. Inventors are now working on new devices that would be fully placed, along with a tiny power pack, in the patient’s chest. The first sample products aren’t expected for another 10 or 20 years: But some people are already worrying that they’ll work-and that America’s overextended health-care programs will lose a precious $2.5 billion to $5 billion a year providing them for a relatively few dying patients. If such expenditures (开支) cut into funding for more basic care, the net effect could actually be a decline in the nation’s health.第31题：According to the passage the Jarvik-7 artificial heart proved to be ________.A) a technical failureB) a technical wonderC) a good life-saverD) an effective means to treat heart disease
