Scott Babcock was carrying out an early morning runway inspection at America\'s farthest north airport when he saw what he thought were a couple of wolves.He took a closer look through his headlights and saw something bigger.Two young polar bears ran away when they saw the Alaska airport worker\'s truck approach.He made sure to videotape their departure.Most airports only worry about wildlife when dealing with bird strikes, but state officials at the airport in the city of Utqiagvik have to prepare for marine mammals that wander in from the Chukchi Sea.A bearded seal weighing about 450 pounds sat down and relaxed on a runway in October after a storm.The Department of Transportation warned pilots of “low seals”.But polar bears are another story.They come with claws, teeth and sometimes they can cause death.And at this time of year, when the sun is down all day for the next few months, polar bears can be hard to see.“Those bears could be 40 yards away from you and you wouldn\'t know it,” said Babcock, the equipment operator.If someone walked out of a building and was trapped between a polar bear and a fence, “things could get real ugly and real fast,” he said.What makes Babcock\'s job more difficult is that polar bears are protected marine mammals.Airport workers are not permitted to run after or attack them.If bears wouldn\'t leave, they call in the wildlife management department of the North Slope Borough.The bears got themselves out of harm\'s way Thursday.They entered the airport before scheduled flights, and 30 mph winds had grounded some local flights.When the bears saw Babcock\'s headlights, they ran to an infield area and eventually a snow dump.The bears hung out for a few hours, disappeared and showed up again Thursday night.An animal control officer may have driven them away, Babcock said.He figured they were hungry.Calls to the North Slope Borough and the U.S.Fish and Wildlife Service, which manages American polar bears, were not immediately returned.1.What did Scott Babcock do when the polar bears were leaving?

【答案】 CBCC 考点：时事新闻类短文阅读 【解析】
试题解析：本文是一篇记叙文。主要介绍了美国最北部的阿拉斯加州的一家机场不仅要应对鸟类撞机这类常有事故，还要应对机场附近北极熊的“入侵”。
1.C.细节理解题。 根据文章第一段最后一句“He made sure to videotape their departure.”可知，他把北极熊离开的情景拍成了视频，故选C。 2.B.细节理解题。 根据文章第五段“What makes Babcock\'s job more difficult is that polar bears are protected marine mammals.”机场工作人员不能追赶或攻击北极熊，故选B。
3.C.推理判断题。 根据第六段“The bears got themselves out of harm\'s way Thursday”以及“They entered the airport before scheduled flights, and 30 mph winds had grounded some local flights”。部分航班停飞，北极熊相对也更安全，所以未受到伤害，故选C。
4.C.主旨大意题。 本文主要报道了北极熊进入美国的机场并给机场带来困扰的事。这家机场不仅要应对鸟类撞机这类常有事故，还要应对机场附近北极熊的“入侵”，故选C。
