A deal is a dealexcept, apparently, when Entergy is involved. The company, a major energy supplier in New England, provoked justified outrage in Vermont last week when it announced it was reneging on a longstanding commitment to abide by the states strict nuclear regulations.

Instead, the company has done precisely what it had long promised it would not: challenge the constitutionality of Vermonts rules in the federal court, as part of a desperate effort to keep its Vermont Yankee nuclear power plant running. Its a stunning move.

The conflict has been surfacing since 2002, when the corporation bought Vermonts only nuclear power plant, an aging reactor in Vernon. As a condition of receiving state approval for the sale, the company agreed to seek permission from state regulators to operate past 2012. In 2006, the state went a step further, requiring that any extension of the plants license be subject to Vermont legislatures approval. Then, too, the company went along.

Either Entergy never really intended to live by those commitments, or it simply didnt foresee what would happen next. A string of accidents, including the partial collapse of a cooling tower in 2007 and the discovery of an underground pipe system leakage, raised serious questions about both Vermont Yankees safety and Entergys managementespecially after the company made misleading statements about the pipe. Enraged by Entergys behavior, the Vermont Senate voted 26 to 4 last year against allowing an extension.

Now the company is suddenly claiming that the 2002 agreement is invalid because of the 2006 legislation, and that only the federal government has regulatory power over nuclear issues. The legal issues in the case are obscure: whereas the Supreme Court has ruled that states do have some regulatory authority over nuclear power, legal scholars say the Vermont case will offer a precedent-setting test of how far those powers extend. Certainly, there are valid concerns about the patchwork regulations that could result if every state sets its own rules. But had Entergy kept its word, that debate would be beside the point.

The company seems to have concluded that its reputation in Vermont is already so damaged that it has nothing left to lose by going to war with the state. But there should be consequences. Permission to run a nuclear plant is a public trust. Entergy runs 11 other reactors in the United States, including Pilgrim Nuclear station in Plymouth. Pledging to run Pilgrim safely, the company has applied for federal permission to keep it open for another 20 years. But as the Nuclear Regulatory Commission (NRC) reviews the companys application, it should keep in mind what promises from Entergy are worth.

A.单用红霉素治疗
B.使用第三代头孢菌素
C.使用青霉素类+β内酰胺酶抑制剂
D.红霉素+第三代头孢菌素
答案:D
解析:

因业务需要,某公司欲将甲、乙、丙、丁、戊、己、庚7个部门合并到丑、寅、卯3个子公司。已知:(1)一个部门只能合并到一个子公司;(2)若丁和丙中至少有一个未合并到丑公司,则戊和甲均合并到丑公司;(3)若甲、乙、庚中至少有一个未合并到卯公司,则戊合并到寅公司且丙合并到卯公司。根据上述信息,可以得出以下哪项?

A.甲丁均合并到丑公司。
B.乙戊均合并到寅公司。
C.乙丙均合并到寅公司。
D.丁丙均合并到丑公司。
E.庚戊均合并到卯公司。
答案:D
解析:
【D】解析:分析推理。设甲-丑,即未到卯,结合条件(3)可知,戊-寅且丙-卯。由“戊-寅”结合条件(2)逆否可得:丁-丑且丙-丑。这种假设推出来的结论“丙-卯”“丙-丑”与条件(1)“一个部门只能合并到一个子公司”不符,假设不成立,所以可得:甲-非丑。再结合条件(2)逆否可得:丁-丑且丙-丑。所以选D。
