单选题The rough guide to marketing success used to be that you got what you paid for. No longer. While traditional "paid" media — such as television commercials and print advertisements — still play a major role, companies today can exploit many alternative forms of media. Consumers passionate about a product may create " owned" media by sending e-mail alerts about products and sales to customers registered with its Website. The way consumers now approach the broad range of factors beyond conventional paid media. Paid and owned media are controlled by marketers promoting their own products. For earned media , such marketers act as the initiator for users' responses. But in some cases, one marketer's owned media become another marketer's paid media — for instance, when an e-commerce retailer sells ad space on its Website. We define such sold media as owned media whose traffic is so strong that other organizations place their content or e-commerce engines within that environment. This trend , which we believe is still in its infancy, effectively began with retailers and travel providers such as airlines and hotels and will no doubt go further. Johnson & Johnson, for example, has created BabyCenter, a standalone media property that promotes complementary and even competitive products. Besides generating income, the presence of other marketers makes the site seem objective, gives companies opportunities to learn valuable information about the appeal of other companies' marketing, and may help expand user traffic for all companies concerned. The same dramatic technological changes that have provided marketers with more and more diverse communications choices have also increased the risk that passionate consumers will voice their opinions in quicker, more visible, and much more damaging ways. Such hijacked media are the opposite of earned media: an asset or campaign becomes hostage to consumers, other stakeholders, or activists who make negative allegations about a brand or product. Members of social networks, for instance, are learning that they can hijack media to apply pressure on the businesses that originally created them. If that happens, passionate consumers would try to persuade others to boycott products, putting the reputation of the target company at risk. In such a case, the company's response may not be sufficiently quick or thoughtful, and the learning curve has been steep. Toyota Motor, for example, alleviated some of the damage from its recall crisis earlier this year with a relatively quick and well-orchestrated social-media response campaign, which included efforts to engage with consumers directly on sites such as Twitter and the social-news site Digg.

单选题Culture shock is the result of the removal of the familiar. Suddenly the individual is faced with the necessity of working, commuting, studying, eating, shopping, relaxing, even sleeping, in an unfamiliar environment organized according to unknown rules. In mild form, culture shock shows itself in symptoms(症状)of fatigue, irritability(易怒)and impatience. Being unable to interpret the situations in which they find themselves, people often believe they are being deliberately deceived or exploited by host-country nationals. They tend to perceive(感觉，觉察到)rudeness where none is intended. Their efficiency and flexibility is often impaired and both work and family suffer. Some people may respond by developing negative stereotypes(老一套)of the host culture, by refusing to learn the language and by mixing exclusively(排外地，专有地)with people of their own cultural background. In extreme cases, rejection may be so complete that the individual returns immediately to their own culture, regardless of the cost in social, economic or personal terms. Alternatively, people may retreat into their own private world, either mentally or physically.

单选题Walking down any of Shanghai"s main shopping streets this week, newcomers might think the locals have been celebrating Christmas for centuries. Christmas may not be a customary holiday in China, but businessmen in Shanghai know it will bring something more valuable than tradition: people willing to spend money. Most Chinese may feel little connection with the Christmas celebration, but with most shops offering discounts (折扣), the message couldn"t be clearer—it is the season to part with one"s hard-earned cash. Much of that marketing drive is directed towards the thousand of foreigners and foreign companies that call Shanghai home. But for Shanghai"s 13 million locals, regardless of personal interest, there seems no avoiding the season"s commercial (商业的) greetings. Along some major roads, nearly every shop window displays some symbols to the holiday: a man-made fir tree (杉树) with lights, or a snowman. With an increasing number of Westerners arriving in the city for work, young Shanghainese, eager to keep pace with the latest Western fashions, have begun to show their interest in Christmas. But some people still don"t think Christmas is an important festival in China. At least it is less important than the New Year and China"s Spring Festival.
