第 29 題
One of the scariest videos on YouTube was recorded by the nose-cone camera of a fighter jet as it was taking off. 26 The pilot spends an agonizing 30 seconds or so trying to regain control, before issuing the order to eject, after which the viewer is treated to a shot of the onrushing ground before the screen goes blank.
Bird strikes are a problem—sometimes a fatal one—for military and civil aviation alike. America's Federal Administration reports that there are about 10,000 such strikes a year to the country's non-military aircraft, costing more than $957 million in damage and delays. 27
Moreover, though relatively few people have been killed in accidents caused by bird strikes, the potential for something horrible to happen is real—as was shown by one of the most famous strikes of recent years. 28 The passengers were saved only by the skill of the pilot, Chelsley Sullenberger, who managed to ditch the plane safely in the Hudson river.
At the moment, attempts to deal with the problem mostly involve efforts to cull flocks of the larger species—geese in particular—in the vicinity of airports, and also the use of bird scarers to try to drive off those actually sitting near runways. 29 There may, however, be a better way. For a decade or more the air forces of several countries have used radar to track birds which might threaten their aircraft. 30 If they work, the old methods of trying to scare birds away, or cull them, can be abandoned.
Choose the best answer from the box below for blank 29.

Choose the best answer from the box below for blank 29.
- A Now, similar systems are being considered for civilian airports.
- B In 2009 an Airbus with 155 people on board hit a flock of geese when it was taking off from LaGuardia airport in New York.
- C As the figures suggest, these approaches do not work well.
- D Just after the plane leaves the runway a large bird comes hurtling towards it and vanishes into the aircraft's engine.
- E The world-wide figure is estimated by the European Space Agency to be $1.2 billion.
思路引導 VIP
觀察第 29 格後方的句子，作者提到「或許有更好的方法（a better way）」，這暗示了前一句話對「現行方法」的評價通常會是什麼？另外，選項中提到的「數據（figures）」在文章前面的段落中有出現過相關的具體數字嗎？

恭喜你精準地掌握了文章的邏輯脈絡！選對 (C) 選項代表你敏銳地觀察到了段落間細微的轉折關係。
語意銜接與代名詞指代
這題的核心在於「承上啟下」。第 29 格的前一句介紹了目前常用的驅鳥方法（撲殺與驚嚇），而格位後方緊接著提到「然而，或許有更好的方法（There may, however, be a better way）」。(C) 選項中的 these approaches（這些做法）正好指代了前述的舊方法，而 As the figures suggest（如數據所示）則巧妙地呼應了前一段落提到的龐大損害金額與事故次數，強化了「現行做法成效不彰」的結論，為後續介紹「雷達追蹤科技」鋪墊了完美的轉折點。
