单选题
Early in January 2009, the temperature in Tanana,
Alaska, fell to 55 below zero F. It was so cold that when the airport runway
lights stopped working, crews were {{U}} {{U}} 1 {{/U}}
{{/U}}from going outside to fix them. So it was a real concern
when Vicky Aldridge, a nurse practitioner at the village health center, realized
that 61-year-old Winkler Bifelt was bleeding {{U}} {{U}} 2
{{/U}} {{/U}}and needed medical treatment at Fairbanks Memorial Hospital,
{{U}} {{U}} 3 {{/U}} {{/U}}150 miles away. The sun was already
down when Aldridge made the {{U}} {{U}} 4 {{/U}} {{/U}}telephone
call to Frontier Flying Service in Fairbanks. "We told them the
only way we could fly was if they could find enough vehicles to {{U}}
{{U}} 5 {{/U}} {{/U}}the runway with headlights so we could land,"
said Bob Hajdukovich, the company's president. Aldridge's next calls went to
airport and town officials, who, {{U}} {{U}} 6 {{/U}} {{/U}},
called villagers. Forty-five minutes later, enough cars, trucks, minivans and
snowmobiles had lined up so that the runway was {{U}} {{U}} 7
{{/U}} {{/U}}. Pilots Nate Thompson and David Fowler landed
without {{U}} {{U}} 8 {{/U}} {{/U}}, and then took off again,
with Bifelt. "There is this wonderful caring {{U}}
{{U}} 9 {{/U}} {{/U}}in the village," Aldridge said. "If anyone
needs anything, all I have to do is to call one or two people and everything
will get {{U}} {{U}} 10 {{/U}} {{/U}}."
单选题
A. objected
B. obstructed
C. obliged
D. observed
【正确答案】
B
【答案解析】[解析] 文章开头介绍了背景：天太冷了，机场跑道的指示灯都“罢工”了。选择该题的选项时，要参考空白处后面的介词。object和oblige需要接介词to，而observe可用于observe sb. doing，不需要介词from。obstruct有“妨碍”的含义，可用于obstruct sb. from doing。
【答案解析】[解析] 第三段开头的句子含义是：飞机起飞的唯一条件是找到足够多的机动车，打开前灯，照亮跑道。要思考四个选项中哪个适合与跑道连用，以便飞机起降。line：在……两侧(1ine the runway：停在跑道两侧)；cross：穿越(显然不合适，有汽车穿越跑道，飞机无法起飞)；span：跨越，穿越；park：停车，接runway不合适。
