根据下列材料请回答 31～35 题：CThe police fired tear gas and arrested more than 5,000 passively resisting protestors Friday in an attempt to break up the largest antinuclear demonstration ever staged in the United States. More than 135,000 demonstrators confronted the police on the construction site of a 1,000-megawatt nuclear power plant scheduled to provide power to most of southern New Hampshire. Organizers of the huge demonstration said that the protest was continuing despite the police actions. More demonstrators were arriving to keep up the pressure on state authorities to cancel the project. The demonstrator had charged that the project was unsafe in the densely populated area, would create thermal pollution in the bay, and had no acceptable means for disposing of its radioactive wasters. The demonstrations would go on until the jails and the courts were so overloaded that the state judicial system would collapse.Governor Stanforth Thumper insisted that there would be no reconsideration of the power project and no delay in its construction set for completion in three years. “This project will begin on time and the people of this state will begin to receive its benefits on schedule. Those who break the law in misguided attempts to sabotage the project will be dealt with according to the law,” he said. And the police called in reinforcements from all over the state to handle the disturbances.The protests began before dawn Friday when several thousand demonstrators broke through the police lines around the cordoned-off construction site. They carried placards that read “No Nukes is Good Nukes,” “Sunpower, Not Nuclear Power,” and “Stop Private Profits from Public Peril.” They defied police order to move from the area. Tear gas canisters fired by the police failed to dislodge the protestors who had been prepared with their own gas masks or facecloths. Finally the gas-masked and helmeted police charged into the crowd to drag off the demonstrators one by one. The protestors did not resist the police, but refused to walk away under their own power. Those arrested would be charged with unlawful assembly, trespassing, and disturbing the peace.第 31 题 What were the demonstrators protesting about?A． Private profits.B． The nuclear power station.C． The project of nuclear power construction.D． Public peril.

DBatteries can power anything from small sensors to large systems. While scientists are finding ways to make them smaller but even more powerful, problems can arise when these batteries are much larger and heavier than the devices themselves. University of Missouri(MU) researchers are developing a nuclear energy source that is smaller, lighter and more efficient.“To provide enough power, we need certain methods with high energy density(密度)”，said Jae Kwon, assistant professor of electrical and computer engineering at MU. “The radioisotope(放射性同位素) battery can provide power density that is much higher than chemical batteries.”Kwon and his research team have been working on building a small nuclear battery, presently the size and thickness of a penny, intended to power various micro / nanoelectromechanreal systems (M/NEMS). Although nuclear batteries can cause concerns, Kwon said they are safe.“People hear the word ‘nuclear’ and think of something very dangerous,” he said, “However, nuclear power sources have already been safely powering a variety of devices, such as pace-makers, space satellites and underwater systems.”His new idea is not only in the battery’s size, but also in its semiconductor(半导体). Kwon’s battery uses a liquid semiconductor rather than a solid semiconductor.“The key part of using a radioactive battery is that when you harvest the energy, part of the radiation energy can damage the lattice structure(晶体结构) of the solid semiconductor,” Kwon said, “By using a liquid semiconductor, we believe we can minimize that problem.”Together with J. David Robertson, chemistry professor and associate director of the MU Research Reactor, Kwon is working to build and test the battery. In the future, they hope to increase the battery’s power, shrink its size and try with various other materials. Kwon said that battery could be thinner than the thickness of human hair.71. Which of the following is true of Jae Kwon?A. He teaches chemistry at MU.B. He developed a chemical battery.C. He is working on a nuclear energy source.D. He made a breakthrough in computer engineering.
Liquid semiconductor is used to _________.A. get rid of the radioactive wasteB. test the power of nuclear batteries.C. decrease the size of nuclear batteriesD. reduce the damage to lattice structure.
Text 2 A deal is a deal-except,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 strict nuclear regulations.Instead,the company has done precisely what it had long promised it would not challenge the constitutionality of Vermont’s rules in the federal court,as part of a desperate effort to keep its Vermont Yankee nuclear power plant running.It’s a stunning move.The conflict has been surfacing since 2002,when the corporation bought Vermont’s 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 plant’s license be subject to Vermont legislature’s approval.Then,too,the company went along.Either Entergy never really intended to live by those commitments,or it simply didn’t foresee what would happen next.A string of accidents,including the partial collapse of a cooling tower in 207 and the discovery of an underground pipe system leakage,raised serious questions about both Vermont Yankee’s safety and Entergy’s management–especially after the company made misleading statements about the pipe.Enraged by Entergy’s 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 that 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 noting left to lose by going to war with the state.But there should be consequences.Permission to run a nuclear plant is a poblic 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 company’s application,it should keep it mind what promises from Entergy are worth.29.In the author’s view,the Vermont case will testA.Entergy’s capacity to fulfill all its promises.B.the mature of states’patchwork regulations.C.the federal authority over nuclear issues.D.the limits of states’power over nuclear issues.

问答题If increased income is spent on more and larger automobiles, larger houses, and increased consumption of other material goods, the results could cause catastrophic resource exhaustion, and pollution. Take the increase of the consumption of oil for instance. The consumption is so huge that the oil reserves might last only a decade or two if not supplemented by imports.Ten years ago it appeared that nuclear power would solve the anticipated energy crisis. Although supplies of uranium fuel were known to be limited and might become exhausted in half a century, the nuclear power plant has for a long time been a favorite project. But work on it has met with grave problems. The fear of possible atomic explosion and the problem of disposing of polluting byproduct waste have slowed down the construction of further nuclear plants. Eventually atomic technology may be able to control these problems, but at present there seems to be little agreement along atomic scientists about when this can be achieved.
