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

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)

The blind man smiled, “I have been keeping goats for decades and can tell one of them is male or female as well as their age according to their voices.The goat you led just now is obviously a male goat, but you said female.The goat is simply a little more than one year old, but you said you had kept it for three years.Moreover, the goat will bleat totally differently when he is led by a stranger instead of his owner.So I can tell the goat does not belong to you!” Only then did the thief understand the whole thing with his head dropped down.

The largest campaign of killing rats in history is set to poison millions of rats on the sub-Antarctic island of South Georgia. Scientists say the campaign planned for 2013 and 2014 will restore beautiful South Georgia to the position it once held as the world’s most important nesting sites for seabirds.

It was sailors in the late 18th century who unintentionally introduced rats to what had been a fresh environment. “If we can destroy the rats, at least 100 million birds will return to their home on South Georgia,” says Tony Martin, a biology professor at the University of Dundee who was invited to lead the project.

South Georgia is by far the largest island to get rid of animals that destroy native wildlife after being introduced deliberately or accidentally by people. Though rats and mice have done the most damage, cats, foxes, goats, deer, rabbits and other species have been targeted in the campaigns around the world.

South Georgia is seven times the size of New Zealand’s Campbell Island, currently the largest area ever killing rats. The successful war against Campbell Island rats was carried our in 2001 with 132 tons of poison dropped from five helicopters.

“New Zealand pioneered the techniques for ridding islands of rats and in fact our operation on South Georgia is based on New Zealand’s technology.” Says Martin. “Some New Zealanders will be helping our campaign, including our chief pilot, Peter Garden, who was also chief pilot for the projects at Campbell Island and Rat Island, in the Aleutian chain of the north Pacific.”

The second and third stages in 2013 and 2014 will involve dropping as much as 300 tons of poison from the air onto every part of the island where rats might live. It is a huge operation, carried out during the stormy southern autumn when the rats are hungry and the risks of poisoning native wildlife are less than in the spring and summer months. “Ideally we’d do in winter but the weather makes that too risky,” Martin says.

The ecological payback will be priceless. But Martin says, “The full benefits will take decades to arrive, because some of these birds are slow to hatch.”

1.According to the passage, how did the rats appear on the sub-Antarctic island of South Georgia ?

A. They were attracted there by wildlife.    

B. They escaped there from Campbell Island.

C. They were introduced there by sailors accidently.

D. They were brought in by people deliberately.

2.Which of the following is True about Peter Garden ?

A. He is in charge of the campaign on the sub-Antarctic island.

B. He will be the only pilot for the project on the sub-Antarctic island.

C. He will benefit a lot from the campaign on the sub-Antarctic island.

D. He made great contributions to the project at Campbell Island and Rat Island.

3.The operation of ridding South Georgia of rats is to carried out in autumn because _________.

A. the war against Campbell Island rats failed in all seasons except autumn.

B. only then do the New Zealanders to help the operation have the spare time.

C. rats then need more food and the operation does less harm to native wildlife.

D. the poison kills rats more effectively than it does in any other season.

4.What can we infer from the passage?.

A. The campaign of killing rats will benefit the native wildlife in a short time.

B. Rats aren’t the only species to be blamed for the disappearance of wildlife.

C. The first stage of killing rats on the sub-Antarctic island didn’t make great achievements.

D. The campaign in South Georgia will fully follow in the footsteps of that on Campbell Island.
