问题    Sixty days walking over ice and snow in temperature as low as -45 °C , with nothing to keep you company except the occasional polar "bear". This is no small achievement. Only a few people have ever walked to the North Pole unassisted, and if Christina Franco succeeds, she will have earned a place in the history books and met one of the few remaining challenges of exploration left to women.
   Her 480-mile journey will begin in northern Canada, dragging a sledge that weighs as much as she does. At the end of each day’s walking or skiing, she will pitch her tent in subzero temperatures, get into a sleeping bag filled with ice, and attempt to sleep to the unsettling background sounds of howling wind and cracking ice, which may or may not signal the approach of one of those polar bears. "I’ll carry a pistol to scare any bears away, " says Franco, 42. "The bears that far north won’t have had contact with humans, fortunately, so they won’t associate me with food, but they will be curious and that’s dangerous. If it uses a paw to see what you are, it could damage your tent—or your arm. I imagine I’ll have quite a few sleepless nights."
   Many of the early polar explorers suffered from disease and injuries, and while modern technology (lightweight materials, satellite phones, places on stand-by to carry out rescue missions) has lessened the dangers, it can never make such an inhospitable landscape anything approaching safe. It can take just five minutes for any uncovered skin to become frostbitten and, once the sun has risen, Franco will only be able to remove her sunglasses inside her tent, otherwise the intensity of the sunlight reflecting off the snow would cause snow blindness. Just to heighten the danger, the cold will slow down her brain functions, so it will be more difficult to make split-second decisions in the event of a sudden crisis.
   She will use about 8, 000 calories a day, losing nearly half a kilogram every 24 hours. "The problem is that the human body can only take on about 5, 500 calories a day, " she says. "So you have to fatten up before you set off or you’ll run out of energy." Franco is currently trying to put on 19 kilos. She may complain about not fitting into any of her dresses, but when Franco weighs herself in front of me and finds she’s lost one kilo rather than gained two, as she’d expected, she’s very upset. "I hope my scales are wrong because, if not, I’ve lost weight, " she says, reaching for one of many bars of chocolate lying around her kitchen. [br] What does Franco say about the danger from polar bears?
选项 A、They could injure her without meaning to.
B、If they are hungry, they might attack her.
C、In that part of the Arctic they are harmless.
D、She will have to shoot any that attacks her.
答案 A
解析 根据第二段中的“The bears that far north won’t have had contact with humans，fortunately, so they won’t associate me with food，but they will be curious and that’s dangerous．If it uses a paw to see what you are，it could damage your tent—or your arm．”可知，佛朗哥认为，北极熊没有与人类接触过，所以它们不会把她当作食物，但是它们可能会对她比较好奇，这样就会出现危险。北极熊会用熊掌去探查她是什么，这样可能会损坏帐篷或她的胳膊。据此可知，北极熊可能会在无意中对她造成伤害，A项正确。
