While Americans have become ever more dependent upon electricity in their daily lives, a crucial part of the system that supports their way of life has not kept up. Yes, the country has built more power plants—enough to create a glut of power in most parts of the country. 【R1】______.
California’ s disastrous partial energy deregulation and the role played by Enron and other energy marketing companies in its power crisis have impeded changes in the national ability to deliver power.
【R2】______. Moreover, the deficiency also includes inadequate coordination among the regions in managing the flow of electricity. These interregional weaknesses are so far the most plausible explanation for the blackout on Thursday.
【R3】______. The problem is with the system of rules, organization, and oversight that governs the transmission networks. It was set up for a very different era and is now caught in a difficult transition.
The transmission networks were built to serve a utility system based on regulated monopolies. In the old days, there was no competition for customers. Today, the mission is to connect buyers and sellers seeking the best deal, irrespective of political boundaries and local jurisdictions.
【R4】______. Yet the power industry is probably not even halfway there in its shift from regulation to the marketplace. The California power crisis and the power-trading scandals sent regulators back to the drawing board, slowing the development of new institutions, rules and investment to make competitive markets work.
【R5】______.
[A] Over all, for more than a decade, the power industry has been struggling with how to move from the old regulation to the new marketplace. This shift was driven by the view that half a century of state regulation had produced power prices that were too high and too varied among states. Factories and jobs were migrating from states with high electric power prices to those with lower prices.
[B] But the transmission system is caught in the middle of the stalled deregulation of the American electric power industry.
[C] As a result, the development of the regional transmission organizations is erratic. More than one-third of the power transmitted is not under the control of regional transmission organizations. Some states fear that their cheap power would be sucked away to other markets; others do not want to subordinate state authority to the Federal Energy Regulatory Commission.
[D] It was unclear when the waters would recede, never mind when life would return to normal. Power may not be restored for weeks. Looting, too. Began to spiral out of control. Mr Nagin, who said the city might be uninhabitable for three months, was forced to order police to concentrate on stopping crime, not saving people.
[E] What’ s preventing greater connection and coordination between regions? The technology exists, and is available; the economic benefits of relieving the bottlenecks between regions far exceeds the costs by many billions of dollars.
[F] Yet, despite claims in the wake of last week’s blackout that the nation has a "third world" power grid, the regional networks are first world. But in one critical aspect, the system has become increasingly vulnerable: in the interconnections among the different regions. Both the number and size of the wires on the borders between regions are inadequate for the rising flow of electricity. This missing part creates the worst bottlenecks in the system.
[G] Since entering the overseas power market in 1993, KEPCO has established several achievements through its distinguished international business strategies to promote electric power development of the world. Based on its long experience and advanced technology gained over 100 years in Korea, KEPCO continues to build up its outstanding reputation as a leading utility company. Moreover, KEPCO embraces challenges and makes bold steps into wider markets in the world by its flair for dynamic activities, which is favorably received in the Philippines, China, Vietnam and Libya.

选项
答案
F
解析
本题考查段落主题句(首句)以及段落的前半部分与段落的后半部分之间的语意连贯性。本段后半部讲“这个缺陷(deficiency)还(also)包括……”,故本题的正确选项应该是F,因为该选项的中间部分(即第一个“But”以后部分)主要论述美国电力系统的缺陷(vulnerable和inadequate),与本段的后半部分在论述内容方面保持一致。“also”一词在本题的解题过程中作用重大。
