单选题{{B}}Passage Two{{/B}} Want a glimpse of the future of health care? Take a look at the way the various networks of people involved in patient care are being connected to one another, and how this new connectivity is being exploited to deliver medicine to the patient—no matter where he or she may be. Online doctors offering advice based on standardized symptoms are the most obvious example. Increasingly, however, remote diagnosis (telemedicine) will be based on real physiological data from the actual patient. A group from the University of Kentucky has shown that by using an off-the-shelf (现成的) PDA (personal data assistance) such as a Palm Pilot plus a mobile phone, it is perfectly feasible to transmit a patient's vital signs over the telephone. With this kind of equipment in a first-aid kit (急救包), the cry asking whether there was a doctor in the house could well be a thing of the past. Other medical technology groups are working on applying telemedicine to rural care. And at least one team wants to use telemedicine as a tool for disaster response—especially after earthquakes. Overall, the trend is towards providing global access to medical data and expertise. But there is one problem. Bandwidth is the limiting factor for transmitting complex medical images around the world—CT scans being one of the biggest bandwidth consumers. Communications satellites may be able to cope with the short-term needs during disasters such as earthquakes, wars or famines. But medicine is looking towards both the second-generation Internet and third-generation mobile phones for the future of distributed medical intelligence. Doctors have met to discuss computer-based tools for medical diagnosis, training and telemedicine. With the falling price of broadband communications, the new technologies should usher in (迎来) an era when telemedicine and the sharing of medical information, expert opinion and diagnosis are common.

单选题It has happened to most of us at one time or another. You"re strolling along the pavement, when suddenly one shoe gets 11 to the ground. With a sinking feeling, you realize you"ve stepped in chewing gum—or worse. Walking through British towns and cities, it"s often 12 to avoid the litter covered across the pavements, roads and green spaces—anything from food wrappers and cigarette butts to bottles, cans and plastic bags. A shocking 30m tonnes of litter are 13 from our streets every day. 14 numerous anti-litter campaigns over the last decade, the amount of litter being dropped is not decreasing. The latest data shows that while there has been a modest 15 of 3% in the amount of litter compared to the previous year, levels have risen since 2004/05. At first glance, the failure of the current strategy to reduce littering substantially is 16 . There are numerous ongoing anti-litter campaigns backed by 17 . In 2005, the government introduced the Clean Neighbourhoods and Environment Act (CNEA) that gave local authorities new powers to 18 businesses and individuals to get rid of litter from their land and to make companies help clear up the rubbish they generate. But the CNEA"s effectiveness depends on 19 local authorities implement it. It is quite possible that you could be 20 for dropping litter in one district, but cross the road on to another local authority"s patch and not be punished for the same offence.

单选题ost episodes of absent-mindedness—forgetting where you left something or wondering why you just entered a room--are caused by a simple lack of attention, says Schacter. "You're supposed to remember something, but you haven't encoded it deeply. " Encoding, Schacter explains, is a special way of paying attention to an event that has a major impact on recalling it later. Failure to encode properly can create annoying situations. If you put your mobile phone in a pocket, for example, and don't pay attention to what you did because you're involved in a conversation, you'll probably forget that the phone is in the jacket now hanging in your wardrobe (衣柜). "Your memory itself isn't failing you," says Schacter. "Rather, you didn't give your memory system the information it needed. " Lack of interest can also lead to absent-mindedness. "A man who can recite sports statistics from 30 years ago," says Zelinski, "may not remember to drop a letter in the mailbox. " Women have slightly better memories than men, possibly because they pay more attention to their environment, and memory relies on just that. Visual cues can help prevent absent-mindedness, says Schacter. "But be sure the cue is clear and available," he cautions. If you want to remember to take a medication (药物) with lunch, put the pill bottle on the kitchen table—don't leave it in the medicine chest and write yourself a note that you keep in a pocket. Another common episode of absent-mindedness, walking into a room and wondering why you're there. Most likely, you were thinking about something else. "Everyone does this from time to time," says Zelinski. The best thing to do is to return to where you were before entering the room, and you'll likely remember.

单选题{{B}}Passage Four{{/B}} There are over 6 000 different computer and online games in the world now. A segment of them are considered to be both educational and harmlessly entertaining. One such game teaches geography, and another trains pilots. Others train the player in logical thinking and problem solving. Some games may also help young people to become more computer literate, which is more important in this technology-driven era. But the dark side of the computer games has become more and more obvious. "A segment of games features anti-social themes of violence, sex and crude language," says David Walsh, president of the National Institute on Media and Family. "Unfortunately, it's a segment that seems particularly popular with kids aged eight to fifteen." One study showed that almost 80 percent of the computer and online games young people preferred contained violence. The investigators said "These are not just games anymore. These are learning machines. We're teaching kids in the most incredible manner what it's like to pull the trigger. What they are not learning are the real-life consequences. " They also said "The new and more sophisticated games are even worse, because they have better graphics and allow the player to participate in even more realistic violent acts." In the game Carmageddon, for example, the player will have driven over and killed up to 33 000 people by the time all levels are completed. A description of the outcome of the game says: "Your victims not only squish under your tires and splatter blood on the windshield, they also get on their knees and beg for mercy, or commit suicide. If you like, you can also {{U}}dismember{{/U}} them. " Is all this simulated violence harmful? Approximately 3 000 different studies have been conducted on this subject. Many have suggested that there is a connection between violence in games and increased aggressiveness in the players. Some specialists downplay the influence of the games, saying that other factors must be taken into consideration, such as the possibility that kids who already have violent tendencies are choosing such games. But could it be that violent games still play a contributing role? It seems unrealistic to insist that people are not influenced by what they see. If that were true, why would the commercial world spend billions of dollars annually for television advertising?
