单选题Custom has not been commonly regarded as a subject of any great moment. The inner workings of our own brains we feel to be uniquely worthy of investigation, but custom, we have a way of thinking, is behavior at its most commonplace. As a matter of fact, it is the other way around. Traditional custom, taken the world over, is a mass of detailed behavior more astonishing than what, any one person can ever evolve in individual actions, no matter how unusual. Yet that is a rather trivial aspect of the matter. The fact of first-rate importance is the predominant role that custom plays in experience and in belief, and the very great varieties it may manifest. No man ever looks at the world with pristine eyes. He sees it edited by a definite set of customs and institutions and ways of thinking. Even in his philosophical probing he cannot go behind these stereotypes; his very concepts of the true and the false will still have reference to his particular traditional customs. John Dewey has said in all seriousness that the part played by custom in shaping the behavior of the individual as over against any way in which he can affect traditional custom, is as the proportion of the total vocabulary of his mother tongue over against those words of his own baby talk that are taken up into the common language of his family. When one seriously studies the social orders that have had the opportunity to develop autonomously, the figure becomes no more than an exact and matter-of-fact observation. The life history of the individual is first and foremost an accommodation to the patterns and standards traditionally handed down in his community. From the moment of his birth the customs into which he is born shape his experience and behavior. By the time he can talk, he is the little creature of his culture, and by the time he is grown and able to take part in its activities, its habits are his habits, its beliefs his beliefs, its impossibilities his impossibilities. Every child that is born into his group will share them with him, and no child born into one on the opposite side of the globe can ever achieve the thousandth part. There is no .social problem it is more obligatory upon us to understand than this of the role of custom. Until we are intelligent as to its laws and varieties, the main complicating facts of human life must remain unintelligible.

单选题Science and politics make uncomfortable bedfellows. Rarely is this more true than in the case of climate change, where it is now time for emergency counseling. One point repeatedly made at last week's climate change congress in Copenhagen was that formulating an action plan to curb climate change is not a job of scientists. Politicians may be left scratching their heads over what to do, but at this stage climate scientists cannot provide more guidance than they did in the 2007 report from the Intergovernmental Panel on Climate Change, for two reasons. First, models will never provide a straightforward prediction of how the climate will change. As one Copenhagen delegate put it: "Tell me what the stock market will do in 100 years and I will tell you what the climate will do. " Second as most climate scientists will agree, their role is not to formulate policy. They can provide more or less apocalyptic(大灾预测的)scenarios of what will happen if emissions hit certain thresholds, from burning forests to disappearing islands. But when politicians ask what is the absolute maximum amount of carbon dioxide we should allow to be pumped out, the answer is, invariably, how much risk do you want to take? There are ways out of the deadlock. As the major climate negotiations in December approach, scientists need to be able to take off their labcoats sometimes and speak as concerned citizens. Some may feel uncomfortable with blurring the line between science and activism, but they should be aware that no one understands the risks better than they do and no one is better placed to give informed opinions. Politicians, for their part, should stop begging climatologists for easy answers. What they need instead is a new breed of advisers to descend from the ivory towers of academia and join the climate fray — people who are willing and able to weight up the risks, costs and benefits of various degrees of action. If all else fails, there may still be the safety net of geoengineering. As we have said on several occasions, this option can no longer be dismissed as fantasy. Reputable scientists are discussing options among themselves and with policy-makers, but the fact that we are even considering it should spur governments to cut emissions, cut them deeply and cut them fast. Geoengineering is no get-out-of-jail-free card; it has dangers of its own. The military are already taking an interest, raising the spectre of climate weapons able to divert rainfall and bring drought. That is the last thing we want.

单选题 In the art of the Middle Ages, we never encounter the personality of the artist as an individual; rather, it is diffused through the artistic genius of centuries embodied in the rules of religious art. Art of the Middle Ages is a sacred script, the symbols and meanings of which were well settled. The circular halo placed vertically behind the head signifies sainthood, while the halo impressed with a cross signifies divinity. By bare feet, we recognize God, the angels, Jesus Christ and the apostles, but for an artist to have depicted the Virgin Mary with bare feet would have been tantamount to heresy. Several concentric, wavy lines represent the sky, while parallel lines represent water or the sea. A tree, which is to say a single stalk with two or three stylized leaves, informs us that the scene is laid on earth. A tower with a window indicates a village; and should an angel be watching from the battlements, that city is thereby identified as Jerusalem. Saint Peter is always depicted with curly hair, a short beard and a tonsure, while Saint Paul always has a bald head and a long beard. Through this system, even the most mediocre talent was elevated by the genius of the centuries. The artist of the early Renaissance broke with tradition at their own peril. When they are not outstanding, they are scarcely able to avoid insignificance and banality in their religious works; and even when they are great, they are no more than the equals of the old masters who passively followed the sacred rules.
