WASHINGTON―The Environmental Protection Agency on Wednesday denied California and 16 other states the right to set their own standards for carbon dioxide emissions (排放) from automobiles.
The E.P.A. administrator, Stephen L. Johnson, said the proposed California rules were preempted (抢在……之前行动) by federal authority and made moot (争论未决的) by the energy bill signed into law by President Bush on Wednesday. Mr. Johnson said California had failed to make a compelling case that it needed authority to write its own standards for greenhouse gas emissions from cars and trucks to help control global warming.
The decision immediately provoked a heated debate over its scientific basis and whether political pressure was applied by the automobile industry to help it escape the proposed California regulations. Officials from the states and numerous environmental groups swore to sue (控告) to overturn the edict rules．
In an evening conference call with reporters, Mr. Johnson defended his agency's decision.
“The Bush administration is moving forward with a clear national solution, not a confusing patchwork of state rules,” he said. “I believe this is a better approach than if individual states were to act alone."
The 17 states―including New York, New Jersey and Connecticut―had waited two years for the Bush administration to issue a ruling on an application to set stricter air quality standards than those adopted by the federal government. The decision technically known as a Clean Air Act waiver, was the first time California was refused permission to carry out its own pollution rules; the federal government had previously granted the state more than 50 waivers(弃权声明书).
The emissions standards California proposed in 2004―but never approved by the federal government―would have forced automakers to cut greenhouse gas emissions by 25 percent in new cars and light trucks by 2020, with the cutbacks to begin in 1990 models.
68. What is one of the possible conclusions of the experiment?
67. The underlined word “officials” (Para．4)most probably refers to“
A. the researchers involved in the experiment
B. the inspectors of the football tournament
C. the referees of the football tournament
D. the observers at the site of the experiment
【解析】C. 短语的理解不仅要基于上下文，也要紧扣短文主题，不论是上下文还是结合短文主题，这里的officials都应该指referees．
66. The findings of the experiment show that _________.
A. errors are more likely when a referee keeps close to the ball
B. the farther the referee is from the incident，the fewer the errors
C. the more slowly the referee runs，the more likely will errors occur
D. errors are less likely when a referee stays in one Spot
【解析】A. 本题涉及实验结果，第四段第二句即是本题答案依据。
65. The number of refereeing errors in the experimental matches was
A. slightly above average
B. higher than in the 1998 World Cup
C. quite unexpected
D. as high as in a standard match
【解析】C. 本题涉及短文第三段关于误判率的要点。第三段第一句句末的a remarkably high number
即是本题答案依据。
