20．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 2013and 2014will 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．"

分析 本文敘述了在南極洲南喬治亞島上進行的大規(guī)模滅鼠運動．18世紀晚期，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)．
解答 32．D 細節(jié)理解題．根據(jù)第二段的"It was sailors in the late 18th century whounintentionally introduced rats to what had been a fresh environment．"可知是18世紀晚期，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．所以老鼠是偶然被海員引進的，故選D．
33．C 細節(jié)理解題．根據(jù)第五段的"Some New Zealanders will be helping ourcampaign，including our chief pilot，Peter Garden，who was also chief pilot for the projects atCampbell 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．故選C．
34．A 細節(jié)理解題．根據(jù)倒數(shù)第二段的"It is a huge operation，carriedout during the stormy southern autumn when the rats are hungry and the risks ofpoisoning native wildlife are less than in the spring and summer months．"可知這場大規(guī)模滅鼠運動在多暴風雨的南方秋季實施，是因為這時候鼠類饑餓，而且毒死本土野生動物的風險比春天和夏天更�。蔬xA．
35．B 推理判斷題．根據(jù)第三段的"Though rats and mice have done the most damage，cats，foxes，goats，deer，rabbitsand other species have been targeted in the campaigns around the world．"可知盡管老鼠和老鼠造成的危害最大，但貓、狐貍、山羊、鹿、兔子和其他物種在全世界的運動中已成為攻擊目標．所以野生動物的消失不能只歸咎于鼠類．故選B．
點評 本文是政治經(jīng)濟類閱讀，主要考查細節(jié)理解題和推理判斷題．在做細節(jié)理解題時，首先根據(jù)題目要求迅速在文章里找出相應的段落、句子或短語．認真比較選項和文中細節(jié)的區(qū)別，在做推理判斷題時不要以個人的主觀想象代替文章的事實，要根據(jù)文章事實進行合乎邏輯的推理判斷．
