     The scene in the Hollywood movie The Day After Tomorrow, where global warming could soon turn the global climate (气候) into a new ice age, may never occur, according to new research.

    The next ice age could be 15,000 years away, say European scientists who last month announced a continuous record of 7.40,000 years of climate data (数据) obtained from the Antarctic ice.                         

     Scientists from 10 nations have now almost completely drilled through a 3,000-meter.depth of ice high in the Antarctic mainland. They figure out that the area where summer temperatures can fall to –40℃, has at least 900,000 years of snowfalls,, kept as neatly as the growth rings of a tree. And the ice and air caught in each layer(层) have begun to answer questions about the climates in the past..

     The results show that there have been eight ice ages in the past 740, 000 years and eight warmer periods. And by comparing the pattern of global conditions today with those of the past, the researchers reported in Nature that the present warm period could last another 15, 000 years.

     Research suggests that there is a very close connection between greenhouse gas levels and global average temperatures. It also shows that carbon dioxide (二氧化碳) levels are the highest for at least 440,000 years.         

     "If people say to you: the greenhouse effect is a good thing because we would go into an ice age otherwise, our data say no, a new ice age is not hanging over our heads,” said Eric Wolff from the British Antarctic Survey. "Now we have eight examples of how the climate goes in and out of ice ages… and you can learn what the rules are that go into the climate models that tell us about the future."

     Scientists found that whenever temperatures rose in the frozen record, so did carbon dioxide level. "In 440,000 years we have never seen greenhouse gas get as thick as it is today," said Dr Wolff.

48. In drilling through the ice in Antarctica, scientists, have found that______.

     A. the lowest temperature there is -40℃     B. the depth of ice is 3,000 meters

     C. the ice has existed for 15,000 years          D. snowfalls are kept in certain patterns

49. The information of the global climate conditions in the past can be obtained through______.

     A. separating carbon dioxide from the air     

   B. examining the growth rings of trees

     C. comparing temperatures in different areas

     D. studying the ice and air caught in each layer

50. We can infer from Eric Wolff's words that_______.

     A. there is something wrong with the data     B. greenhouse effect is always a bad thing

     C. a new ice age will not come in the near future

     D. greenhouse gas will get thick in the future

51. What would be the best title for the passage?

     A. Research over the Antarctic area.                    B. Warm period to last about 15, 000 years.

     C. Report on the eight ice ages in the past.    D. Hollywood movies and the global climate.

The disaster at the Chernobyl(former USSR前苏联) power station happened quickly and without warning. It was in the early hours of April 26, 1986 when the cooling system of the reactor(反应堆) failed. Minutes later, a violent (猛烈地) explosion blew the top off the reactor and blasted(爆炸生成) a huge cloud of radioactive gas high into atmosphere. Two people were killed immediately. Hundreds received powerful radiation overdose (过量). And more than 25,000 had to be taken away from their homes.
Days later, the radioactive cloud had spread as far as Scotland. Its radiation was weak, but all over Europe radioactive rain was falling. In some areas people were advised not to eat fresh vegetables, or drink fresh milk, and the sale of meat was forbidden.
The accident at Chernobyl was the world’s worst nuclear accident. In Britain, it convinced (使……相信) many people that all nuclear power stations should be shut down for good. But the Central Electricity Generating Board didn’t agree. They claimed that ·similar disasters could not happen in Britain because of safer designs, fewer deaths are caused using nuclear fuel (燃料) than by mining for coal or drilling for oil and gas. Nuclear accidents are unusually fewer compared with other types of accidents-such as air crashes, fires or dam break-down more nuclear power stations are necessary because the world’s supplies of oil, coal and natural gas are running out.
In 1957 in Cumbria (Britain) a nuclear reactor overheated and caught fire. No one was killed but fourteen workers received radiation overdose. Small amounts of gas and dust were let out over the local countryside.
An official report said the accident was nearly a full-scale disaster. The Nuclear Authority wanted the report published but the Prime Minister at the time refused. He thought that it would make people less confident in Britain’s nuclear industry. Thirty years later, the cabinet(内阁) records of 1957 were published. Only then did the public discover what had really happened in Cumbria.
【小题1】. One result of the Chernobyl nuclear disaster was that ______.

A.25,000 people were killed
B.fresh foods were polluted
C.people in Scotland were taken away from their homes
D.hundreds of houses in Chernobyl were destroyed
【小题2】.According to the passage, nuclear accidents______.
A.are most unlikely to cause deathB.are always kept secret from the public
C.can only happen in underdeveloped countriesD.may happen in any country that has nuclear power station.
【小题3】. After the nuclear accident at Chernobyl many people in Britain _______.
A.still believed it could not happen in their country.
B.were not convinced that nuclear power stations could be safe
C.accepted that there would be fewer deaths than in drilling for oil
D.supported nuclear power stations because world fuel supplies were low
【小题4】.. The British Government refused to publish the report on the Cumbria accident because _______.
A.Britain’s supplies of oil, coal and gas were running out
B.it takes thirty years for the effects of radiation to appear
C.fewer people died in that accident than in other types of accidents
D.it was concerned that the British people would doubt their country’s nuclear expertise (核技术)
