Question

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.”

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?.

試題分析： 本文敘述了在南極洲南喬治亞島上進(jìn)行的大規(guī)模滅鼠運(yùn)動。18世紀(jì)晚期，海員無意間把老鼠引入到南極洲南喬治亞島這個清新的環(huán)境，為了讓鳥類重回這里，他們開始滅鼠。估計這所產(chǎn)生的效益會在幾十年的時間里完全實現(xiàn)。

1.細(xì)節(jié)理解題。根據(jù)第二段“It was sailors in the late 18th century who unintentionally introduced rats to what had been a fresh environment.”可知是18世紀(jì)晚期，海員無意間把老鼠引入到南極洲南喬治亞島這個清新的環(huán)境。故答案選C。

2.細(xì)節(jié)理解題。根據(jù)“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, ”可知Peter Garden是滅鼠工程的首席飛行員，所以他為Campbell島和鼠島的滅鼠工程做出了卓越貢獻(xiàn)。故答案選 D。

3.細(xì)節(jié)理解題。根據(jù)“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.”可知這場大規(guī)模滅鼠運(yùn)動在多暴風(fēng)雨的男方秋季實施，是因為這時候鼠類饑餓，而且毒死本土野生動物的風(fēng)險比春天和夏天更小。故答案選C。

4.推理題。根據(jù)“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.”盡管鼠類危害最大，貓狐貍山羊鹿兔子和其他物種在全世界范圍內(nèi)被定為目標(biāo)�？芍�野生動物的消失不能只歸咎于鼠類。故答案選B。
