填空题As companies continue to cut costs, the days of frequent promotions are a distant memory. So are the days of endless opportunities to show off your skills. Layoff survivors, faced with fewer options are finding themselves in career purgatory—there's no way up and no way out. After talking to career coaches, managers, recruiters, and psychologists, Fortune put together eight tips to help workers break free from the inertia. 41. Avoid taking cover Don't hide out behind your computer. "You should really work to increase or maintain the visibility that you have," says David Opton, founder and CEO of career management firm ExecuNet. Build a circle of allies Fortify your current relationships and work on making new ones, both within and outside the office. "Allies will be helpful in terms of letting you know information, like if there's a job possibility that comes up," says Dee Soder, founder of the CEO Perspective Group. Who you know can make a big difference, especially in difficult times. 42. Load up on new tools This is the perfect time to acquire new expertise. (If the boss can't pay, do it on your own.) 43. Look beyond your job description People don't get promotions just because they do their jobs well; they get promotions because they take initiative. Lauren Doliva, a partner at recruiting firm Heidrick Struggles International, has a client looking to hire a CO0. 44. Manage your own PR "Doing well is part productivity and part publicity," says Marilyn Moats Kennedy, a managing partner at Career Strategies. Be creative Remember, says Doliva, "people hire us to think, not just to do." This is the perfect time to tackle the project that you've always wished you had more time for. Soder recommends scheduling an hour each day to work on extra things such as new initiatives or ways to improve your job or that of those above you. Take responsibility for your success Be proactive, not reactive. Says Kennedy: "If you're waiting for something to happen to you, it's not going to be anything positive." Figure out your goals and let managers know what they are; identify your weaknesses and work on them; find better ways to harness your strengths. For nontangible skills— leadership, management, communication—coaches recommend hiring a coach. A client of Soder's was put into a new management role, but didn't feel like she had what it took to oversee a bigger team. She went out and hired a coach who helped her learn how to interact with top executives as well as how to run a bigger territory. She has since been promoted again. Taking responsibility for your own success is something everyone should do, regardless of external factors. Otherwise you're heading straight for burnout. 45. Adjust your attitude Don't panic. Even though the economy is in a recession, your career is not coming to an end. How you look at the situation will have a big impact on whether you stay stuck or move ahead. "One can choose to say there is no opportunity or one can choose to look for it," says Doliva. In fact, many coaches believe that being stuck is just a state of mind. [A] Let people know when you accomplish something or when you put in the extra effort to get a project done early. Without being cheesy, make sure that you're giving off the right vibes by keeping a positive attitude, avoiding emotional outbursts, and appearing calm and organized. And don't forget to look the part. Many didn't get promotions because of their professional presence—grooming, clothes, and body language. [B] When someone brought up the VP of operations, who was the obvious candidate for the job, the CEO rejected him outright. "He said no because the VP only does what's expected," says Doliva. "The CEO didn't see him as someone who would take the risks and the time to do the job better. " Now is not the time for complacency, even if you're not gunning for a spot in the executive suite. Coaches suggest that employees come in early, stay late, and take on extra projects. Little things can make a big difference. [C] Brush up on computer skills, audit a class, or get a certificate or degree in your field—and when jobs do open up, you'll be ready. [D] "What you don't want to do is start getting depressed", adds Melissa Karz, founder of Kadima Coaching. "Be what you want to attract." It might be helpful to hunt for motivation in other places. "Now is the time to start taking a look at how fulfilling your life is outside of work," says Lois Frankel, president of Corporate Coaching International. Find exciting activities to replenish yourself with—and then bring that positive spirit into the office. [E] Amid all of the layoffs, you've managed to keep your job—but the chances of moving up are slim to none. Nobody above you is going to leave now, and there's no money for special projects to prove yourself. You're stuck. Here's how to avoid fading into the woodwork. [F] Speak up in meetings, join task forces; and volunteer for difficult projects that co-workers aren't willing to tackle.

填空题"Universal history, the history of what man has accomplished in this world, is at bottom the History of the Great Men who have worked here," wrote the Victorian stage Thomas Carlyle. Well, not any more it is not. Suddenly, Britain looks to have fallen out with its favourite historical form. This could be no more than a passing literary craze, but it also points to a broader truth about how we now approach the past: less concerned with learning from forefathers and more interested in feeling their pain. Today, we want empathy, not inspiration. From the earliest days of the Renaissance, the writing of history meant recounting the exemplary lives of great men. In 1337, Petrarch began work on his rambling writing De Viris Illustribus—On Famous Men, highlighting the virtus (or virtue) of classical heroes. Petrarch celebrated their greatness in conquering fortune and rising to the top. This was the biographical tradition which Niccolo Machiavelli turned on its head. In The Prince, the championed cunning, ruthlessness, and boldness, rather than virtue, mercy and justice, as the skills of successful leaders. Over time, the attributes of greatness shifted. The Romantics commemorated the leading painters and authors of their day, stressing the uniqueness of the artist's personal experience rather than public glory. By contrast, the Victorian author Samual Smiles wrote Self-Help as a catalogue of the worthy lives of engineers, industrialists and explores. "The valuable examples which they furnish of the power of self-help, if patient purpose, resolute working and steadfast integrity, issuing in the formulation of truly noble and many character, exhibit," wrote Smiles. "what it is in the power of each to accomplish for himself" His biographies of James Walt, Richard Arkwright and Josiah Wedgwood were held up as beacons to guide the working man through his difficult life. This was all a bit bourgeois for Thomas Carlyle, who focused his biographies on the truly heroic lives of Martin Luther, Oliver Cromwell and Napoleon Bonaparte. These epochal figures represented lives hard to imitate, but to be acknowledged as possessing higher authority than mere mortals. Communist Manifesto. For them, history did nothing, it possessed no immense wealth nor waged battles: "It is man, real, living man who does all that. "And history should be the story of the masses and their record of struggle. As such, it needed to appreciate the economic realities, the social contexts and power relations in which each epoch stood. For: "Men make their own history, but they do not make it just as they please; they do not make it under circumstances chosen by themselves, but under circumstances directly found, given and transmitted from the past. " This was the tradition which revolutionized our appreciation of the past. In place of Thomas Carlyle, Britain nurtured Christopher Hill, EP Thompson and Eric Hobsbawm. History from below stood alongside biographies of great men. Whole new realms of understanding—from gender to race to cultural studies—were opened up as scholars unpicked the multiplicity of lost societies. And it transformed public history too: downstairs became just as fascinating as upstairs. [A] emphasized the virtue of classical heroes. 41. i Petrarch [B] highlighted the public glory of the leading artists. 42. Niccolo Machiavelli [C] focused on epochal figures whose lives were hard to imitate. 43. Samuel Smiles [D] opened up new realms of understanding the great men in history. 44. Thomas Carlyle [E] held that history should be the story of the masses and their record ofstruggle. 45. Marx and Engels [F] dismissed virtue as unnecessary for successful leaders. [G] depicted the worthy lives of engineer industrialists and explorers.

填空题[A] Mark Williams and Jason Mattingley, whose study has just been published in Current Biology, looked at the way a person’s sex affects his or her response to emotionally charged facial expressions. People from all cultures agree on what six basic expressions of emotion look like. Whether the face before you is expressing anger, disgust, fear, joy, sadness or surprise seems to be recognised universally — which suggests that the expressions involved are innate, rather than learned. [B] Moreover, most participants could find an angry face just as quickly when it was mixed in a group of eight photographs as when it was part of a group of four. That was in stark contrast to the other five sorts of expression, which took more time to find when they had to be sorted from a larger group. This suggests that something in the brain is attuned to picking out angry .expressions, and that it is especially concerned about angry men. Also, this highly tuned ability seems more important to males than females, since the two researchers found that men-picked out the angry expressions faster than women did, even though women were usually quicker than men to recognized every other sort of facial expression. [C] Dr Williams and Dr Mattingley showed the participants in their study photographs of these emotional expressions in mixed sets of either four or eight. They asked the participants to look for a particular sort of expression, and measured the amount of time it took them to find it. The researchers found, in agreement with previous studies, that both men and women identified angry expressions most quickly. But they also found that anger was more quickly identified on a male face than a female one. [D] Men are notoriously insensitive to the emotional world around them. At least, that is the stereotype peddled by a thousand women’s magazines. And a study by two researchers at the University of Melbourne, in Australia, confirms that men are, indeed, less sensitive to emotion than women, with one important exception. Men are acutely sensitive to the anger of other men. [E] Dr Williams and Dr Mattingley suspect the reason for this is that being able to spot an angry individual quickly has a survival advantage — and, since anger is more likely to turn into lethal violence in men than in women, the ability to spot angry males quickly is particularly valuable. [F] The ability to spot quickly that an alpha male is in a foul mood would thus have great survival value. It would allow the sharp-witted time to choose appeasement, defence or possibly even pre-emptive attack. And, if it is right, this study also confirms a lesson learned by generations of bar-room tough guys and schoolyard bullies: if you want attention, get angry.[G] As to why men are more sensitive to anger than women, it is presumably because they are far more likely to get killed by it. Most murders involve men killing other men — even today the context of homicide is usually a spontaneous dispute over status or sex.(作图)
