It began as just another research project, in this case to examine the effects of various drugs on patients with a severe mood disorder. Using an advanced brain scanning technology—the clumsily named echo-planar magnetic resonance spectroscopic imaging (磁共振光谱成像) procedure, or EP–MRSI—researchers at Boston’s McLean Hospital scanned the medicated and un-medicated brains of 30 people with bipolar disorder in order to detect possible new treatments for the more than 2 million American adults who suffer from the disease.But something unexpected happened. A patient who had been so depressed that she could barely speak became ebullient after the 45-minute brain scan. Then a second patient, who seemed incapable of even a smile, emerged actually telling jokes. Then another and another. Was this some coincidence? Aimee Parow, the technician who made these observations didn’t think so. She mentioned the patients’ striking mood shifts to her boss and together they completely refocused the study: to see if the electromagnetic fields might actually have a curative effect on depressive mood.As it turns out, they did. As reported last month in the American Journal of Psychiatry, 23 of the 30 people who were part of the study reported feeling significantly less depressed after the scan. The most dramatic improvements were among those who were taking no medication. The researchers are cautious. Says Bruce Cohen, McLean’s president and psychiatrist in chief: “I want to emphasize that we are not saying this is the answer but this is a completely different approach in trying to help the brain than anything that was done before.It’s a completely different approach because of the way the magnetism is applied to the brain. But it’s an example of new research on an old idea: that the brain is an electromagnetic organ and that brain disorders might result from disorder in magnetic function. The idea has huge appeal to psychiatrists and patients alike, since for many people the side effects of psychiatric (精神的) drugs are almost as difficult to manage as the disease itself. And 30 percent of the nearly 18.8 million people who suffer from depression do not respond to any of the antidepressants available now. People with other severe mental disorders might benefit as well. And while no one fully understands exactly why or how the brain responds as it does to electrical currents and magnetic waves, fascinating new research is offering some possible explanations.1.

Last month, the public address system at Earl’s Court subway station in London was ordered to get the noise down. Passengers, it seems, had had enough of being told the blindingly obvious: “Stand back or the train will run you over.” “Don’t lean on the doors.” “Stand back from the opening doors.” “Do this.” “Don’t do that.”Bossiness is not just aural. It is also written. As a commuter, I’m continually bombarded by notices on car walls. “Please take your feet of the seat.” “Please turn down your personal stereo.” And when I drive past the local primary, a sign flashes: “School. Slow down!”The presumption behind these signs is that Britons must have everything spelled out because we are tow, uncivilized people who were raised by wolves. Britain didn’t use to be so bossy. When I was a boy, for instance, the local cinema put a warming on screen before we settled down to watch. “Don’t,” it said, “make noises.” In those days, long before mobile phones, it was the only bossiness we saw in the cinema. Since then, bossiness has become more commonplace. Television, that strongest guide to public morals and lifestyles in this country, is alive with dominant people. On screen, we see health experts holding some poor woman’s breasts and demanding that she get in shape. Cooking programs tell us not to think of leaving toast crumbs on the kitchen table.There is no point in blaming TV for this new bossiness. We want to be bossed. We have behaved badly and now we yearn to feel the whip to correct us. On July 1, smoking will be banned in public places in England. My local government told churches in the area last week that no-smoking posters must be prominently displayed by church entrances.I love this: the governments are bossing people to make them bossier. They are insisting that priests tell their congregations (教区的教民) what to do.My local government isn’t the only source of bossiness. I find it everywhere. But the rise in bossiness does not seem to have been accompanied by a rise in socially well-adjusted behavior. In fact, the opposite. Perhaps this is because, if you feel as though you are treated with contempt, you will respond with the same.1. The case at Earl’s Court subway station shows that（）.2. It is presumed that bossiness is everywhere because Britons（）.3. It is suggested in the passage that（）.4. According to the passage, which of the following statements is true?5.

Did your mum and dad go to university, or did they leave school and go straight to the Job Centre? The educational experience of parents is still important when it comes to how today’s students choose an area of study and what to do after graduation, according to The Future-track research in the UK.The research was done by the Higher Education Careers Service Unit. It plans to follow university applicants for six years from 2006 through their early careers.The first year’s findings come from a study of 130,000 university applicants. They show significant differences in prospective students’ approach to higher education, depending on whether their parents got degrees (second-generation applicants) or didn’t (first-generation applicants).First-generation applicants were more likely to say that their career and employment prospects were uppermost in their minds in deciding to go to university. About one-fifth of this group gave “to enable me to get a good job” as their main reason for choosing HE. And 37 percent said that a degree was “part of my career plan”.A young person coming from a non-professional household where finances are stretched may find the idea of learning for its own sake to be a luxury. This explains the explosion in vocational courses.At Portsmouth University, first-year student Kim Burnett, 19, says that she specifically chose her degree in health research management and psychology to get a secure, well-paid job. Harriet Edge, 20, studying medicine at Manchester University, also wanted job security. Her parents lacked college degrees, though the fact that her uncle is a doctor appears to have influenced her choice.“Medicine is one of those fields where it’s pretty likely you’ll get a job at the end. That’s a big plus, as the debt levels after five years of study are going to be frightening,” she says. Many experts believe that this situation affects those with no family tradition of higher education far more keenly. The fact that 26 percent of respondents said that they needed more advice implies that some students may end up feeling that their higher education investment was not worthwhile.For those with graduate parents, this lack of guidance may, the researchers suggest, be less of a problem. “But, for those without the advantages, lack of access to career guidance before applying for higher education leaves them exposed to making poorer choices,” the survey concludes.1. The main idea of the passage is that（）.2. “HE” in the 4th paragraph probably refers to（）.3. A young person coming from a non-professional household（）.4. In which of the following aspects do Kim Burnett and Harriet Edge have in common?5. It is implied that（）.

It did say that the price of goods and services at universities have risen rapidly. Some of the fastest growth has been in employee health（4）, and professional salaries.Living expenses on campus have also（5）.
