单选题If those "mad moments"—when you 'can't remember what your friend has told you or where you left your keys—are becoming more frequent, mental exercises and a healthy brain diet may help. Just as bodies require more maintenance with the passing years, so do brains, which scientists now know show signs of aging as early as the 20s and 30s. "Brain aging starts at a very young age, younger than any of us had imagined and these processes continue gradually over the years," said Dr. Gary Small, the director of the Center on Aging at the University of California, Los Angeles. "I'm convinced that it is never too early to get started on a mental or brain-fitness program," he added. In his book, The Memory Bible, the 51-year-old neuroscientist (神经学家) lists what he refers to as the 10 suggestions for keeping the brain young. They include training memory, building skills, reducing stress, mental exercises; brain food and a healthy lifestyle. It's a game plan for keeping brain cells sparking and neural networks in perfect shape. "Misplacing your keys a couple of times don't mean you should start labeling your cabinets. Memory loss is not an inevitable consequence of aging. Our brains can fight back," he said. Small provides the weapons for a full-scale attack. Simple memory tests give an indication of what you are up against and tools such as "look" and "connect" are designed to make sure that important things such as names and dates are never forgotten. "So if you wanted to learn names and faces, for example, you meet Mrs. Beatty and you notice a distinguishing facial feature, maybe a high eyebrow," said Small. "You associate the first thing that comes to mind. I think of the actor Warren Beatty so I create a mental picture of Warren Beatty kissing her brow." Small admits it may sound a bit strange but he says it works. "Mental exercises could be anything from doing crossword puzzles and writing with your left hand if you are right handed or learning a language. It could be anything that is fun that people enjoy doing," he added. He also recommends physical exercise, a low-fat diet and eating foods rich in fatty acids, such as fish, nuts, and fruits and vegetables high in antioxidants (抗氧化剂) including blueberries and onions in addition to reducing stress.

单选题Ants first captured the attention of software engineers in the early 1990s. A single ant cannot do much on its own, but a group of ants (51) can solve complex problems. That inspired people like Marco Dorigo, who is one of the founders of a (52) known as group intelligence. Ants are good at choosing the shortest possible route between a food (53) and their nest. This reminds us of a classic computational travelling-salesman problem. Given a list of cities and their (54) apart, the salesman must find the shortest route needed to visit each city once. As the number of cities (55) , the problem gets more complicated. Ants solve their own problem using chemical signals called pheromones (信息素), when an ant finds food, she takes it back to the nest, (56) a pheromone trail that will attract others. The more ants that (57) the trail, the stronger it becomes. (58) , the pheromones evaporate (挥发) quickly, so once all the food has been collected, the trail soon goes cold. This rapid evaporation means long trails are less (59) than short ones, all else being equal. Pheromones thus turn the (60) intelligence of the individual ants into something more powerful.

单选题{{B}}Passage Two{{/B}}
In 1998 consumers could purchase
virtually anything over the Internet. Books, compact discs, and even stocks were
available from World Wide Web sites that seemed to spring up almost daily. A few
years earlier, some people had predicted that consumers accustomed to shopping
in stores would be reluctant to buy things that they could not see or touch in
person. For a growing number of time-starved consumers, however, shopping from
their home computer was proving to be a convenient alternative to driving to the
store. A research estimated that in 1998 U.S. consumers would
purchase ＄ 7.3 billion of goods over the Internet, double the 1997 total.
Finding a bargain was getting easier, owing to the rise of online auctions and
Web sites that did comparison shopping on the Internet for the best
deal. For all the consumer interest, retailing in cyberspace was
still a largely unprofitable business, however. Internet pioneer Amazon.
com, which began selling books in 1995 and later branched into recorded music
and videos, posted revenue of $153.7 million in the third quarter, up from ＄
37.9 million in the same period of 1997．Overall, however, the company's loss
widened to ＄ 45.2 million from $ 9.6 million, and analysts did not expect the
company to turn a profit until 2003．Despite the great loss, Amazon com had a
stock market value of many billions, reflecting investors' optimism about the
future of the industry. Internet retailing appealed to investors
because it provided an efficient means for reaching millions of consumers
without having the cost of operating conventional stores with their armies of
salespeople. Selling online carried its own risks, however. With so many
companies competing for consumers' attention, price competition was intense and
profit margins thin or nonexistent. One video retailer sold the hit movie
Titanic for ＄ 9.99, undercutting (削价) the ＄19.99 suggested retail price and
losing about ＄ 6 on each copy sold．With Internet retailing still in its initial
stage, companies seemed willing to absorb such losses in an attempt to establish
a dominant market position.

单选题Holding on to hope may not make patients happier as they deal with chronic illness or diseases, according to a new study by University of Michigan Health System researchers.
"Hope is an important part of happiness," said Peter A. Ubel M. D., director of the U-M Center for Behavioral and Decision Sciences in Medicine and one of the authors of the happily hopeless study, "but there"s a dark side of hope. Sometimes, if hope makes people put off getting on with their life, it can get in the way of happiness."
The results showed that people do not adapt well to situations if they are believed to be shortened. Ubel and his co-authors—both from U-M and Carnegie Mellon University—studied patients who had new colostomies: their colons were removed and they had to have bowel movements in a pouch that lies outside their body.
At the time they received their colostomy, some patients were told that the colostomy was reversible-that they would undergo a second operation to reconnect their bowels after several months. Others were told that the colostomy was permanent and that they would never have normal bowel function again. The second group, the one without hope, reported being happier over the next six months than those with reversible colostomies.
"We think they were happier because they got on with their lives. They realized the cards they were dealt, and recognized that they had no choice but to play with those cards," says Ubel, who is also a professor in the Department of Internal Medicine.
"The other group was waiting for their colostomy to be reversed," he added. "They contrasted their current life with the life they hoped to lead, and didn"t make the best of their current situation."
"Hopeful messages may not be in the best interests of the patient and may interfere with the patient"s emotional adaptation," Ubel says. "I don"t think we should take hope away. But I think we have to be careful about building up people"s hope so much that they put off living their lives."
