问题 The following paragraphs are given in a wrong order. For Questions 41-45, you are required to reorganize these paragraphs into a coherent article by choosing from the list A-G. Some of the paragraphs have been placed for you. (10 points)

A. Electronics should also make it technically easier to charge cars the proper costs for road congestion. Road-side sensors could identify and charge cars at a high rate during busy periods, and less or nothing at other times. The trouble is that the technology looks easier to develop than the political will to use it. Drivers are as hooked on cars as smokers are on cigarettes. This is true not only when there are few alternatives, as in rural America, but even in cities such as Paris, with a highly developed urban rail system and stinging petrol taxes. Indeed, even colossal traffic jams, for all their cost in wasted time, have failed to deter motorists.
B. There are 500 million cars on the world’s roads today, ten times as many as 50 years ago. By 2030 there could be a billion, plus another 500 million lorries and motorcycles. That is splendid news: few things transform lives for the better as fast and as thoroughly as access to a car. Yet even drivers admit that more cars (other people’s, of course) will also bring heavy costs, notably in air pollution and congestion.
C. Indeed, all political action to reduce car use seems as gridlocked as downtown New York. California, which pioneered innovations such as catalytic converters to reduce carbon-monoxide emissions and car-sharing on highway, has backed off its demand that 2% of new sales should be "zero emission vehicles" (i.e. electric cars) in 1998. This was not merely the result of lobbying; battery technology is simply not good enough to make electric cars attractive. Petrol taxes remain highly unpopular in America. In Europe, although high fuel taxes are more widely accepted, experiments to reduce congestion by charging car commuters have repeatedly been postponed.
D. Over the past 20 years, technical fixes have made cars far cleaner. Now the fixes will get fewer; and sheer traffic growth will soon swamp any gains. Cleaning up city air is also easier than curbing output of carbon dioxide, a gas thought to cause climate change. Road transport accounts for one-fifth of world carbon-dioxide out-put, and the share may grow as developing countries get wheels. Congestion makes things worse: cars stuck in traffic jam pollute three times as much as those on the open road. But the simple answer to the building more roads-is increasingly expensive and politically unacceptable.
E. Yet something must be done about the future rise in congestion and pollution. The best approach is to tackle what remains the fundamental cause of both problems: the fact that the full external costs of each car journey (in congestion, pollution and accidents) are not home by the motorist. That suggests using the tax system in harness with market forces to limit the growth of car travel and to coax motorists into more environmentally friendly behavior.
F. As with cigarette taxes, higher taxes on car use in general look like good ways to raise revenue. It is surely sensible to tax socially and economically damaging behavior rather than such desirable activities as saving and hard work. If voters see such taxes as substitutes for more undesirable ones, they may grudgingly accept them. But they will always be more unpopular than taxes merely aimed at persuading drivers to switch, for instance, those that have successfully promoted unleaded over leaded petrol. Taxes of this sort should be able to boost sales of less polluting cars such as today’s natural-gas vehicles and tomorrow’s hybrid electric cars, which will use tiny internal-combustion engines running at a steady, low-polluting rate to generate electricity for the engine.
G. New technology ought to make this easier. A promising way to load the pollution costs of motoring on to motorists may be a plan developed by green activists in Germany. This would implant an electronic smart card in cars’ engine-management systems, to monitor the quantity of polluting emissions. The results would then be totted up every year to produce a tax bill.

Order: B is the first paragraph, and F is the last one.
