单选题 At the present time, 98 percent of the world energy consumption comes from stored sources, such as fossil fuels or nuclear fuel. Only hydroelectric and wood energy represent completely renewable sources on ordinary time scales. Discovery of large additional fossil fuel reserves, solution of the nuclear safety and waste disposal problems, or the development of controlled thermonuclear fusion will provide only a short-term solution to the world's energy crisis. Within about 100 years, the thermal pollution resulting from our increased energy consumption will make solar energy a necessity at any cost. Man's energy consumption is currently about one part in ten thousand that of the energy we receive from the sun. However, it is growing at a 5 percent rate, of which about 2 percent represents a population growth and 3 percent a per capita energy increase. If this growth continues, within 100 years our energy consumption will be about 1 percent of the absorbed solar energy, enough to increase the average temperature of the earth by about one degree centigrade if stored energy continues to be our predominant source. This will be the point at which there will be significant effects in our climate, including the melting of the polar ice caps, a phenomenon which will raise the level of the oceans and flood parts of our major cities. There is positive feedback associated with this process, since the polar ice cap contributes to the partial reflectivity of the energy arriving from the sun: As the ice caps begin to melt, the reflectivity will decrease, thus heating the earth still further. It is often stated that the growth rate will decline or that energy conservation measures will preclude any long-range problem. Instead, this only postpones the problem by a few years. Conservation by a factor of two together with a maintenance of the 5 percent growth rate the problem by only 14 years. Reduction of the growth rate to 4 percent postpones the problem by only 25 years; in addition, the inequities in standards of living throughout the world will provide pressure toward an increase in growth rate, particularly if cheap energy is available. The problem of a changing climate will not be evident until perhaps ten years before it becomes critical due to the nature of an exponential growth rate together with the normal annual weather variations. This may be too short a period to circumvent the problem by converting to other energy sources, so advance planning is a necessity. The only practical means of avoiding the problem of thermal pollution appears to be the use of solar energy. (Schemes to "air-condition" the earth do not appear to be feasible before the twenty-second century. ) Using the solar energy before it is dissipated to heat does not increase the earth's energy balance. The cost of solar energy is extremely favorable now, particularly when compared to the cost of relocating many of our major cities.

单选题In most American cities, the tent for a one-bedroom apartment was $250 or more per month in recent years. In some smaller cities such as Louisville, Kentucky or Jacksonville, Florida the rent was less, but in larger cities it was more. For example, if you lived in Los Angeles, you had to pay $400 or more to rent a one-bedroom apartment, and the same apartment rented for $625 and up in Chicago. The most expensive rents in the U. S. were in New York City, where you had to pay at least $700 a month to rent a one-bedroom apartment in most parts of the city. Renters and city planners are worried about the high cost of renting apartments. Many cities now have rent-control laws to keep the cost of renting low. These laws help low-income families who cannot pay high rents. Rent control in the United States began in 1943 when the government imposed rent controls on all American cities to help workers and the families of soldiers during World War II. After the war, only one city—New York—continued these World War II controls. Recently, more and more cities have returned to rent controls. At the beginning of the 1980s, nearly one fifth of the people in the United States lived in cities with rent-control laws. Many cities have rent-control laws, but why are rents so high? Builders and landlords blame rent controls for the high rents. Rents are high because there are not enough apartments to rent, and they blame rent controls for the shortage of apartments. Builders want more money to build more apartment buildings, and landlords want more money to repair their old apartment buildings. But they cannot increase rents to get this money because of the rent-control laws. As a result, landlords are not repairing their old apartments, and builders are not building new apartment buildings to replace the old apartment buildings. Builders are building apartments for high-income families, not low-income families, so low-income families must live in old apartments that are in disrepair. Builders and landlords claim that rent-control laws really hurt low-income families. Many renters disagree with them. They say that rent control is not the problem. Even without rent controls, builders and landlords will continue to ignore low-income housing because they can make more money from high-income housing. The only answer, they claim, is more rent controls and government help for low-income housing.

单选题I have observed that the Americans show a less decided taste for general ideas than the French. This is especially true in politics. Although the Americans infuse into their legislation far more general ideas than the English, and although they strive more than the latter to adjust the practice of affairs to theory.no political bodies in the U-nited States have ever shown so much love for general ideas as the Constituent Assembly and the Convention in France. At no time has the American people laid hold on ideas of this kind with the passionate energy of the French people in the eighteenth century, or displayed the same blind confidence in the value and absolute truth of any theory. This difference between the Americans and the French originates in several causes, but principally in the following one. The Americans are a democratic people who have, always directed public affairs themselves. The French are a democratic people who for a long time could only speculate on the best manner of conducting them. The social condition of the French led them to conceive very general ideas on the subject of government, while their political constitution prevented them from correcting those ideas by experiment and from gradually detecting their insufficiency; whereas in America the two things constantly balance and correct each other. It may seem at first sight that this is very much opposed to what I have said before, that democratic nations derive their love of theory from the very excitement of their active life. A more attentive-examination will show that there is nothing contradictory in the proposition. Men living in democratic countries eagerly lay hold of general ideas because they have but little leisure and because these ideas spare them the trouble of studying particulars. This is true, but it is only to be understood of those matters which are not the necessary and habitual subjects of their thoughts. Mercantile men will take up very eagerly, and without any close scrutiny, all the general ideas on philosophy, politics, science, or the arts which may be presented to them;but for such as relate to commerce, they will not receive them with-out inquiry or adopt them without reserve. The same thing applies to statesman with regard to general ideas in politics. If, then, there is a subject upon which a democratic people is peculiarly liable to abandon itself, blindly and extravagantly, to general ideas, the best corrective that can be used will be to make that subject a part of their daily practical occupation. They will then be compelled to enter into details, and the details will teach them the weak points of the theory. This remedy may frequently be a painful one, but its effect is certain. Thus it happens that the democratic institutions which compel every citizen to take a practical part in the government moderate that excessive taste for general theories in polities which the principle of equality suggests.

单选题Habits are a funny thing. We reach for them mindlessly, setting our brains on auto-pilot and relaxing into the unconscious comfort of familiar routine. "Not choice, but habit rules the unreflecting herd." William Wordsworth said in the 19th century. In the ever-changing 21st century, even the word "habit" carries a negative connotation. So it seems antithetical to talk about habits in the same context as creativity and innovation. But brain researchers have discovered that when we consciously develop new habits, we create parallel synaptic paths, and even entirely new brain cells, that can jump our trains of thought onto new, innovative tracks. Rather than dismissing ourselves as unchangeable creatures of habit, we can instead direct our own change by consciously developing new habits. In fact, the more new things we try—the more we step outside our comfort zone—the more inherently creative we become, both in the workplace and in our personal lives. But don"t bother trying to kill off old habits, once those ruts of procedure are worn into the brain, they"re there to stay. Instead, the new habits we deliberately ingrain into ourselves create parallel pathways that can bypass those old roads. "The first thing needed for innovation is a fascination with wonder," says Dawna Markova, author of "The Open Mind". "But we are taught instead to "decide," just as our president calls himself "the Decider."" She adds, however, that "to decide is to kill off all possibilities but one. A good innovational thinker is always exploring the many other possibilities." All of us work through problems in ways of which we"re unaware, she says. Researchers in the late 1960s discovered that humans are born with the capacity to approach challenges in four primary ways: analytically, procedurally, relationally (or collaboratively) and innovatively. At the end of adolescence, however, the brain shuts down half of that capacity, preserving only those modes of thought that have seemed most valuable during the first decade or so of life. The current emphasis on standardized testing highlights analysis and procedure, meaning that few of us inherently use our innovative and collaborative modes of thought. "This breaks the major rule in the American belief system—that anyone can do anything," explains M.J.Ryan, author of the 2006 book "This Year I Will..." and Ms. Markova"s business partner. "That"s a lie that we have perpetuated, and it fosters commonness. Knowing what you"re good at and doing even more of it creates excellence." This is where developing new habits comes in.
