[单项选择]A factory that makes uranium fuel for nuclear reactors had a spill so bad it kept the plant closed for seven months last year and became one of only three events in all of 2006 serious enough for the Nuclear Regulatory Commission to include in an annual report to Congress. After an investigation, the commission changed the terms of the factory’s license and said the public had 20 days to request a hearing on the changes.
But no member of the public ever did. In fact, no member of the public could find out about the changes. The document describing them, including the notice of hearing rights for anyone who felt adversely affected, was stamped "official use only," meaning that it was not publicly accessible.
The agency would not even have told Congress which factory was involved were it not for the efforts of Gregory B. Jaczko, one of the five commissioners. Mr. Jaczko identified the company, Nuclear Fuel Services of Erwin, Tenn,, in a memorandum that became part of the public
A. Because the general public often show no interest in such matters.
B. Because the hearing rights of the public are adversely affected.
C. Because the public has stamped the documents "official use only".
D. Because the public are not aware of the changes in the first place.

[简答题]
As technology continues to advance, countries must decide how they will deal with the issue of human cloning for reproduction or research. So far, several nations have placed strong restrictions on healing cloning; others are moving towards such restrictions, and a few have staked out positions in favor of curative cloning. After months of bitter debate, the Unite States must decide what it will do.
All legislators can agree that it would be wrong now to make a walking, talking, reallife human clone. The National Academy of Sciences also supports that position. But its institute of Medicine has rightly said that its objections to the safety of reproductive cloning do not apply to research cloning. Indeed,’ some scientists say that research cloning could yield stem cells that could be used to grow healing tissues for patients with diseases such as Parkinson’s. (47)They also say that studying stem cells made from the cells of diseased patients could he -
[单项选择]Most of the people who appear most often and most gloriously in the history books are great conquerors and generals and soldiers, whereas the people who really helped civilization forward are often never mentioned at all. We do not know who first set a broken leg, or launched a seaworthy boat, or calculated the length of the year, or manured a field; but we know all about the killers and destroyers. People think a great deal of them, so much so that on all the highest pillars in the great cities of the world you will find the figure of a conqueror or a general or a soldier. And I think most people believe that the greatest countries are those that have beaten in battle the greatest number of other countries and ruled over them as conquerors. It is just possible they are, but they are not the most civilized. Animals fight; so do savages; hence to be good at fighting is to be good in the way in which an animal or a savage is good, but it is not to be civilized. Even being good at getting
A. most history books were written by conquerors, generals and soldiers.
B. no one who really helped civilisation forward is mentioned in any history book.
C. history books neglect the real heroes behind civilisation.
D. conquerors, generals and soldiers should not be mentioned in history books.

[单项选择]Plato asked "What is man" and St Augustine asked "Who am I’ A new breed of criminals has a novel answer: "I am you!" Although impostors have existed for ages, the growing frequency and cost of identity theft is worrisome. Around 10m Americans are victims annually, and it is the leading consumer-fraud complaint over the past five years. The cost to businesses was almost $50 billion, and to consumers $5 billion, in 2002, the most recent year that America’s Federal Trade Commission collected figures.
After two recent, big privacy disasters, people and politicians are calling for action. In February, ChoicePoint, a large data-collection agency, began sending out letters warning 145,000 Americans that it had wrongly provided fraudsters with their personal details, including Social Security numbers. Around 750 people have already spotted fraudulent activity. And on February 25th, Bank of America revealed that it lost data tapes that contain personal information on over lm government emp
A. raise philosophical questions.
B. show an obvious contrast.
C. introduce the criminals,
D. pave the way for the main topic.

[填空题]
Do mobile phones cause explosions at petrol stations That question has just been exhaustively answered by Adam Burgess, a researcher at the University of Kent, in England. Oddly, however, Dr Burgess is not a physicist, but a sociologist. For the concern rests not on scientific evidence of any danger, but is instead the result of sociological factors: it is an urban myth, supported and propagated by official sources, but no less a myth for that. Dr Burgess presented his findings this week at the annual conference of the British Sociological Association.
Mobile phones started to become widespread in the late 1980s, when the oil industry was in the middle of a concerted safety drive, Dr Burgess notes. This was, in large part, a response to the Piper Alpha disaster in 1988, when 167 people died in an explosion on an oil platform off the Scottish coast. 41.______So nobody questioned the precautionary ban on the use of mobile phones at petrol stations. The worry was that an ele -
[单项选择]The history of modem pollution problems shows that most have resulted from negligence and ignorance. We have an appalling tendency to interfere with nature before all of the possible consequences of our actions have been studied in depth. We produce and distribute radioactive substances, synthetic chemicals and many other potent compounds before fully comprehending their effects on living organisms. Our education is dangerously incomplete.
It will be argued that the purpose of science is to move into unknown territory, to explore, and to discover. It can be said that similar risks have been taken before, and that these risks are necessary to technological progress.
These arguments overlook an important element. In the past, risks taken in the name of scientific progress were restricted to a small place and brief period of time. The effects of the processes we now strive to master are neither localized nor brief. Air pollution covers vast urban areas. Ocean pollutants have bee
A. Unconcerned.
B. Humorous.
C. Serious.
D. Exaggerated.
