单选题The great chariot of society, which for so long had run down the gentle slope of tradition, now found itself powered by an internal combustion engine. Transactions and gain 21 a new and startling 22 force. What forces could have been 23 powerful to smash a comfortable and 24 world and institute in its place this new society? There was no single massive 25 . It was not great events, single adventures, individual laws, or charming 26 which 27 about the economic revolution. It was a process of internal growth. First, there was the gradual emergence of national political 28 in Europe. A second great current of change was to be found in the slow decay of the religious spirit under the 29 of the skeptical, inquiring, humanist views of the Italian Renaissance. Still another 30 current lies in the slow social changes that eventually 31 the market system possible. In the 32 of this change, power naturally began to gravitate into the hands of those who understood money matters-the merchants. Perhaps most important of all in the pervasiveness of its effect was a rise in scientific curiosity. 33 the world would wait until the age of Adam Smith for its 34 burst of technology, the Industrial Revolution could net have taken place had not the ground been prepared 35 a succession of basic sub-industrial discoveries. No single one of these currents, acting by itself, could have turned society 36 . Indeed, many of them may have been as much the 37 as the causes of a great convulsion in human organization. History turns no 38 corners, and the whole vast upheaval sprawled out over time. Evidences of the market way of life sprang up side by side with older traditional ways, and remnants of the former day 39 long after the market had for all practical purposes taken over the 40 principle of economic organization.

单选题This leaves us with the challenge of finding some politically practicable way to reduce greenhouse gas emissions. But it is an awkward truth that when most U.S. senators were asked informally in 2000 if they would support the Kyoto Protocol should President George W. Bush send it to the Senate for ratification , the overwhelming majority, Democrats as well as Republicans, said they could not. The reason for the liberals"surprising reply is clear. Many studies, not all by conservatives, suggest that full compliance with the terms of the Kyoto Protocol would likely lead to a deep American recession. For those willing to Fun this risk, sober reflection on the consequences of the economic collapse of 1929 and the subsequent worldwide depression with all its political and ultimately military consequences is certainly in order. That said, what can be done, in particular by our own country? Independent of the issues raised by the Kyoto Protocol, and given the weight of evidence that the problem of global warming is serious and fraught with dire consequences, failure to do anything at all and instead to promote "business as usual" is downright criminal. Yet the Bush administration has given no more than lip service to the problem, though that could be changing. It is one thing to weigh alternatives and implement compromises that reflect the complexity of the problem; it is quite another thing to do nothing, especially if doing nothing is just a way of securing support from certain industries that worsen the problem. There are, after all, things that can be done. Reopening a serious international dialogue, and not just saying a few good words, would be a useful if inadequate start. Not every problem must be solved before the weight of evidence becomes so compelling that certain initial steps become almost mandatory. We already know how to make more fuel-efficient automobiles, yet no national policy has surfaced to accomplish this. The scientific and engineering communities are the ones best suited to identify the scientific research that is still needed and the technical projects that show the greatest promise. These issues should be decided by them and not the politicians. Once solutions look promising, as a few already do, industry will be all too ready to jump in, for at that stage there is money to be made. And only a fool would underestimate human ingenuity when given a proper incentive, or the strength of American industry once the boiler is lit under it.
