Women who drank three or more cups of coffee a day were 30 percent less likely to have memory decline at age 65 than whose who drank one cup or less daily. And the benefit increased with age. Women over age 80 who drank three or more cups of coffee a day were about 70 percent less likely to have memory decline than those who drank one cup or less. the researchers said.
Caffeinated tea had the same effect in the women. the study found, although more was needed to get the same caffeine boost. "Count roughly two cups of tea for a cup of coffee," said study leader Karen Ritchie of INSERM, the French National Institute for Health and Medical Research. But the researchers didn&39;t find a similarly protective effect in men, although other studies have found a benefit to males.
How might caffeine help ward off cognitive decline? "It is a cognitive stimulant." said Ritchie. It also helps to reduce levels of the protein called beta amyloid in the brain. she said. "whose accumulation is responsible for Alzheimer&39;s disease but which also occurs in normal aging."
Ritchie said she wasn&39;t sure why men in the study didn&39;t benefit from caffeine. "Our hypothesis is that either women metabolize caffeine differently than men, or there may be an interaction of the caffeine with the sex hormones.the estrogen-progesterone balance," she said.
The French study confirms previous research, said William Scott. professor of medicine at the University of Miami Miller School of Medicine. who has researched caffeine&39;s beneficial effects against Parkinson&39;s disease, also a neurodegenerative disorder.

参考答案：C
首段第2句概括了该段的主要内容，句中的benefit指的是记忆衰退的减缓。因此本段内容为：年龄越长，记忆衰退就比同龄人越慢,即C。本段关注的是咖啡影响记忆的衰退程度，而非咖啡是否能增强记忆，A.D（记忆力的好坏）在本段并未论及；虽然本段对比了喝三杯或更多咖啡的女性与喝一杯或更少的女性的记忆衰退程度，但这并不意味着咖啡喝得越多越好，因此，B、D中的themorecoffeethewomandrank这个前提不正确，故两项均错。

Early in the age of affluence（富裕）that followed World War II, an American retailing analyst named Victor Lebow proclaimed, "Our enormously productive economy... demands that we make consumption our way of life, that we convert the buying and use of goods into rituals, that we seek our spiritual satisfaction, our ego satisfaction, in consumption...We need things consumed, burned up, worn out, replaced and discarded at an ever increasing rate."

The health-care economy is filled with unusual and even unique economic relationships. One of the least understood involves the peculiar roles of producer or "provider" and purchaser or "consumer" in the typical doctor-patient relationship. In most sectors of the economy, it is the seller who attempts to attract a potential buyer with various inducements of price, quality, and utility, and it is the buyer who makes the decision, Such condition, however, does not prevail in most of the health-care industry.
In the health-care industry, the doctor-patient relationship is the mirror image of the ordinary relationship between producer and consumer. Once an individual has chosen to see a physician-and even then there may be no real choice-it is the physician who usually makes all significant purchasing decisions: whether the patient should return "next Wednesday", whether X-rays are needed, whether drugs should be prescribed, etc. It is a rare and sophisticated patient who will challenge such professional decisions or raise in advance questions about price, especially when the disease is regarded as serious.
This is particularly significant in relation to hospital care. The physician must certify the need for hospitalization, determine what procedures will be performed, and announce when the patient may be discharged. The patient may be consulted about some of these decisions, but in the main it is the doctor&39;s judgments that are final. Little wonder then that in the eye of the hospital it is the physician who is the real "consumer." As a consequence, the medical staff represents the "power center" in hospital policy and decision-making, not the administration.
