单选题The classic difficulty felt with democracy arises from the fact that democracy can never express the will of the whole people because there never exists any such unchanging will (at least in any society that call itself democratic). The concept of government of the whole people by the whole people must be looked on as being in the poetry rather than in the prose of democracy; the fact of prose is that real democracy means government by some kind of dominant majority. And the ever-present danger, repeatedly realized in fact, is that this dominant majority may behave toward those who are not of the majority in such a manner as to undermine the moral basis of the right of people, because they are people, to have some important say in the setting of their own course and in the use of their own faculties. Other forms of government may similarly fail to respect human independence. But there is at least no contradiction in that; the underlying assumption of every kind of government by wisers and betters is that people on the whole are not fit to manage their own affairs, but must have someone else do it for them, and there is no paradox when such a government treats its subjects without respect, or deals With them on the basis of their having no rights that the government must take into account. But democracy affirms that people are fit to control themselves, and it cannot live in the same air with the theory that there is no limit to the extent to which public power--even the power of a majority--can interfere with the lives of people. Rational limitation on power is therefore not a contradiction to democracy, but is of the very essence of democracy as such. Other sorts of government may impose such limitations on themselves as an act of grace. Democracy is under the moral duty of limiting itself because such limitation is essential to the survival of that respect for humankind which is in the foundations of democracy. Respect for the freedom of all people cannot, of course, be the only guide, for there would then be no government. Delicate ongoing compromise is what must be looked for. But democracy, unless it is to deny its own moral basis, must accept the necessity for making this compromise and for giving real weight to the claims of those without the presently effective political power to make their claims prevail in elections.

单选题My problem with food began when I graduated from high school. About that time. I began eating out a lot. There were two fast-food restaurants near the place where I worked, so I ate lunch at one or the other almost every day. I found it much easier to go to a fast-food restaurant than to prepare my own lunch. When I moved away from home my eating habits got worse. I didn"t know how to cook, and I didn"t have much money; but my favorite fast-food restaurant was just two blocks away. Eating there seemed like the easiest and cheapest option. In addition to eating the wrong kind of food, I ate way too much. I wasn"t satisfied with a standard fast-food meal. I ordered more French fries, a larger soft drink, and an extra hamburger—whatever I could afford—in the largest size available. The turning point came when I was in my late 20"s. I started thinking more seriously about my health. I was overweight. I felt sluggish all the time, and I lacked self-confidence. I knew that I needed to make changes. So I began to try to get my eating under control. I took a gradual approach. First, I reduced the amount of food I ate. I would tell myself, "This isn"t my last meal; I can always eat again." At times I literally had to walk away from the dinner table. But I felt good afterward, as if I had won a victory. Besides I had to give up something completely. For example, I eliminated soft drinks and drank only water. That was difficult. I loved soft drinks, and I hated water. After I drank a glass of water, I would take a small cup of juice, which put some flavor in my mouth. After a while, water itself became more appealing. Now I still do go out to eat occasionally. But when I do, I control how much I eat. If the portion I"m served is too big, I ask for a take-out box. Then I put half of the meal in the box before I start eating. That way, I consume a reasonable portion instead of eating.

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 " earned media" by willingly promoting it to friends, and company may leverage "owned" media by sending E-mail alerts about products and sales to customers registered with its Web site. In fact, the way consumers now approach the process of making purchase decisions means that marketing's impact stems from a 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 Web site. 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 stand-alone 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To which of the following statements would Matthew Simmons most likely agree?

单选题Patients tend to feel indignant and insulted of the physician tells them he can find no organic cause for the pain. They tend to interpret the term "psychogenic" to mean that they are complaining of nonexistent symptoms. They need to be educated about the fact that many forms of pain have no underlying physical cause but are the result, as mentioned earlier, of tension, stress or hostile factors in the general environment. Sometimes a pain may be a manifestation of "conversion hysteria". Obviously, it is folly for an individual to ignore symptoms that could be a warning of a potentially serious illness. Some people are so terrified of getting news from a doctor that they allow their malaise to worsen, sometimes past the point of no return. Total neglect is not the answer to hypochondria. The only answer has to be increased education about the way the human body works; so that more people be able to steer an intelligent course between promiscuous pill-popping and irresponsible disregard of genuine symptoms. Of all forms of pain, none is important for the individual to understand than the "threshold" variety. Almost everyone has a telltale ache that is triggered whenever tension or fatigue reaches a certain point. It can take the form of a migraine-type headache or a squeezing pain deep in the abdomen or cramps or a pain in the lower back or even in the joints. The individual who has learned how to make the correlation between such threshold pains and their cause doesn"t panic when they occur; he or she does something about relieving the stress and tension. Then, if the pain persists despite the absence of apparent cause, the individual will telephone the doctor.
