单选题A: Have a nice weekend! B: ______

单选题"Years ago, a friend of mine observed that 80 percent of the people in this country have too much self-esteem and 20 percent have much too little. That struck me as pretty accurate, but psychologists will tell you that self-esteem is not a constant. People"s appraisal of their own worth varies I have the impression that more people have unstable self-esteem than before. I say this because some of the traditional standards people used to measure their own worth have eroded (middle class respectability), whereas more people now seem to measure themselves against celebrities and superstars. It would be interesting to know if anybody has studied changes in the criteria we use to measure self-worth." Comment 1: You bring up an interesting point because I do believe values and beliefs have changed. It would be very interesting to see the criteria used for self-worth. I find it hard to believe that only 20% of people have low self-esteem. I"ve been following Brene Brown"s thoughts on the subject of self-worth, and low self-worth (on some level) seems much more common. Comment 2: If the quality of one"s self-esteem is going to be judged by comparisons with those who are celebrities and superstars, then the entire exercise is really pointless. Comment 3: Self-esteem solution: A happy marriage. Comment 4: Ego (self-worth) is proportionate to wealth. The more wealth, the more self-worth. Comment 5: Benjamin Franklin said it best, and it applies to all facets of life. "Contentment will make a poor man rich just as discontent will make a rich man poor." It does not mean not try to do your best, or be the richest. It simply means once you"ve done your best be content with yourself, just as if you don"t give your best effort discontent is sure to follow. Comment 6: I"ve "retired" from 30 years of expensive, if interesting, "personal growth" and "self-improvement", much probably motivated by trying to "fix" myself. Hanging out with friends at a local café is way more satisfying. Comment 7: A related concept you may be interested in is the "sociometer theory" of self-esteem, pioneered by Mark Leary (Wake Forest). Basically it states that our self-esteem is determined by the amount of perceived social acceptance/rejection, and that determination is full of cognitive biases and errors. Awesome stuff.

单选题"We"ve seen a 1 of people, people who have had longstanding problems with their sleep, who report that their sleep is getting worse because of the added stress of the economy, 2 people who are coming in, saying that they"ve never had a sleep problem before." 3 for sleep medications are at a record high. 4 if pill popping doesn"t sound like the solution, consider a good old-fashioned power-nap. "You can nap 5 sleep loss, so after the fact, or you can nap in anticipation (预测，预料) of sleep loss because only sleep can replace sleep." And napping may be just the ticket. Business is booming here at Yelo Wellness where believe it or not, people in Manhattan will pay nearly $30 for a 40-minute 6 . "I just think it makes a real 7 first of all in my work, I do a better job, which means I"m gonna get a better bonus, and I"m not gonna burn 8 ." Two thirds of adults say sleepiness interferes with their concentration and makes handling stress on the job more difficult. Regulars here say the fee 9 is a small price to pay to overcome exhaustion. "Coming here, spending the money, taking a nap allows me to kind of burn the candle at 10 ends."

单选题"Museum" is a slippery word. It first meant (in Greek) anything consecrated to the Muses: a hill, a shrine, a garden, a festival or even a textbook. Both Plato"s Academy and Aristotle"s Lyceum had a mouseion, a muses" shrine. Although the Greeks already collected detached works of art, many temples—notably that of Hera at Olympia (before which the Olympic flame is still lit)—had collections of objects, some of which were works of art by well-known masters, while paintings and sculptures in the Alexandrian Museum were incidental to its main purpose. The Romans also collected and exhibited art from disbanded temples, as well as mineral specimens, exotic plants, animals; and they plundered sculptures and paintings (mostly Greek) for exhibition. Meanwhile, the Greek word had slipped into Latin by transliteration (though not to signify picture galleries, which were called pinacothecae) and museum still more or less meant "Muses" shrine". The inspirational collections of precious and semi-precious objects were kept in larger churches and monasteries—which focused on the gold-enshrined, bejewelled relics of saints and martyrs. Princes, and later merchants, had similar collections, which became the deposits of natural curiosities: large lumps of amber or coral, irregular pearls, unicorn horns, ostrich eggs, fossil bones and so on. They also included coins and gems—often antique engraved ones—as well as, increasingly, paintings and sculptures. As they multiplied and expanded, to supplement them, the skill of the fakers grew increasingly refined. At the same time, visitors could admire the very grandest paintings and sculptures in the churches, palaces and castles; they were not "collected" either; but "site-specific", and were considered an integral part both of the fabric of the buildings and of the way of life which went on inside them—and most of the buildings were public ones. However, during the revival of antiquity in the fifteenth century, fragments of antique sculpture were given higher status than the work of any contemporary, so that displays of antiquities would inspire artists to imitation, or even better, to emulation; and so could be considered Muses" shrines in the former sense. The Medici garden near San Marco in Florence, the Belvedere and the Capitol in Rome were the most famous of such early "inspirational" collections. Soon they multiplied, and, gradually, exemplary "modern" works were also added to such galleries. In the seventeenth century, scientific and prestige collecting became so widespread that three or four collectors independently published directories to museums all over the known world. But it was the age of revolutions and industry which produced the next sharp shift in the way the institution was perceived: the fury against royal and church monuments prompted antiquarians to shelter them in asylum-galleries, of which the Musee des Monuments Francais was the most famous. Then, in the first half of the nineteenth century, museum funding took off, allied to the rise of new wealth: London acquired the National Gallery and the British Museum, the Louvre was organized, the Museum-Insel was begun in Berlin, and the Munich galleries were built. In Vienna, the huge Kunsthistorisches and Naturhistorisches Museums took over much of the imperial treasure. Meanwhile, the decline of craftsmanship (and of public taste with it) inspired the creation of "improving" collections. The Victoria and Albert Museum in London was the most famous, as well as perhaps the largest of them.

单选题Being sociable looks like a good way to add years to your life. Relationships with family, friends, neighbours, even pets, will all do the trick, but the biggest longevity (长寿) boost seems to come from marriage or an equivalent relationship. The effect was first noted in 1858 by William Fair, who wrote that widows and widowers (鳏夫) were at a much higher risk of dying than their married peers. Studies since then suggest that marriage could add as much as seven years to a man"s life and two to a woman"s. The effect holds for all causes of death, whether illness, accident or self-harm. Even if the odds are stacked against you, marriage can more than compensate. Linda Waite of the University of Chicago has found that a married older man with heart disease can expect to live nearly four years longer than an unmarried man with a healthy heart. Likewise, a married man who smokes more than a pack a day is likely to live as long as a divorced man who doesn"t smoke. There"s a flip side, however, as partners are more likely to become ill or die in the couple of years following their spouse"s death, and caring for a spouse with mental disorder can leave you with some of the same severe problems. Even so, the odds favour marriage. In a 30-years study of more than 10,000 people, Nicholas Christakis of Harvard Medical School describes how all kinds of social networks have similar effects. So how does it work? The effects are complex, affected by socio-economic factors, health-service provision, emotional support and other more physiological (生理的) mechanisms. For example, social contact can boost development of the brain and immune system, leading to better health and less chance of depression later in life. People in supportive relationships may handle stress better. Then there are the psychological benefits of a supportive partner. A life partner, children and good friends are all recommended if you aim to live to 100. The ultimate social network is still being mapped out, but Christakis says: "People are interconnected, so their health is interconnected."

单选题In the first year or so of Web business, most of the action has revolved around efforts to tap the consumer market. More recently, as the Web proved to be more than a fashion, companies have started to buy and sell products and services with one another. Such business-to-business sales make sense because business people typically know what product they"re looking for. Nonetheless, many companies still hesitate to use the Web because of doubts about its reliability. "Businesses need to feel they can trust the pass way between them and the supplier," says senior analyst Blane Erwin of Forrester Research. Some companies are limiting the risk by conducting online transactions only with established business partners who are given access to the company"s private intranet. Another major shift in the model for Internet commerce concerns the technology available for marketing. Until recently, Internet marketing activities have focused on strategies to "pull" customers into sites. In the past year, however, software companies have developed tools that allow companies to "push" information directly out to consumers, transmitting marketing messages directly to targeted customers. Most notably, the Pointcast Network uses a screen saver to deliver a continually updated stream of news and advertisements to subscribers" computer monitors. Subscribers can customize the information they want to receive and proceed directly to a company"s website. Companies such as Virtual Vineyards are already starting to use similar technologies to push messages to customers about special sales, product offerings, or other events. But push technology has earned the contempt of many Web users. Online culture thinks highly of the notion that the information flowing onto the screen comes there by specific request. Once commercial promotion begins to fill the screen uninvited, the distinction between the Web and television fades. That"s a prospect that horrifies Net purists. But it is hardly inevitable that companies on the Web will need to resort to push strategies to make money. The examples of Virtual Vineyards, Amazon.com, and other pioneers show that a website selling the right kind of products with the right mix of interactivity, hospitality, and security will attract online customers. And the cost of computing power continues to free fall, which is a good sign for any enterprise setting up shop in silicon. People looking back 5 or 10 years from now may well wonder why so few companies took the online plunge.

单选题Tides are created mainly by the pull of the moon on the earth. The moon"s pull causes water in the oceans to be a little deeper at a point closest to the moon and also at a point farthest from the moon, on the opposite side of the earth. These two tidal "waves" follow the apparent movement of the moon around the earth and strike nearly every coast line at intervals of about twelve hours and twenty-five minutes. After reaching a high point, the water level goes down gradually for a little more than six hours and then begins to rise towards a new high point. Hence, most coast lines have two tides a day, and the tides occur fifty minutes later each day. Differences in the coast line and in channels in the ocean bottom may change the time that the tidal wave reaches different points along the same coast line. The difference in water level between high and low tide varies from day to day according to the relative positions of the sun and the moon because the sun also exerts a pull on the earth, although it is only about half as strong as the pull of the moon. When the sun and the moon are pulling along the same line, the tides rise higher, and when they pull at right angles (直角) to one another, the tide is lower. The formation of the coast line and variations in the weather are additional factors which can affect the height of tides. Some sections of the coast are shaped in such a way as to cause much higher tides than in other areas. A strong wind blowing towards the shore may also cause tides to be higher.

单选题Someday a stranger will read your e-mail without your permission or scan the Websites you"ve visited, or perhaps someone will casually glance through your credit card purchases or cell phone bills to find out your shopping preferences or calling habits. In fact, it"s likely some of these things have already happened to you. Who would watch you without your permission? It might be a spouse, a girlfriend, a marketing company, a boss, a cop or a criminal. Whoever it is, they will see you in a way you never intended to be seen—the 21st century equivalent of being caught naked. Psychologists tell us boundaries are healthy, that it"s important to reveal yourself to friends, family and lovers in stages, at appropriate times. But few boundaries remain. The digital bread crumbs (碎屑) you leave everywhere make it easy for strangers to reconstruct who you are, where you are and what you like. In some cases, a simple Google search can reveal what you think. Like it or not, increasingly we live in a world where you simply cannot keep a secret. The key question is: Does that matter? For many Americans, the answer apparently is "no". When opinion polls ask Americans about privacy, most say they are concerned about losing it. A survey found an overwhelming pessimism about privacy, with 60 percent of respondents saying they feel their privacy is "slipping away, and that bothers me". But people say one thing and do another. Only a tiny fraction of Americans change any behaviors in an effort to preserve their privacy. Few people turn down a discount at tollbooths (收费站) to avoid using the EZ-Pass system that can track automobile movements. And few turn down supermarket loyalty cards. Privacy economist Alessandro Acquisti has run a series of tests that reveal people will surrender personal information like Social Security numbers just to get their hands on a pitiful 50-cents-off coupon (优惠券). But privacy does matter—at least sometimes. It"s like health: When you have it you don"t notice it. Only when it"s gone do you wish you"d done more to protect it.
