4 Beware—polar bear!

Chapter Four BEWARE—POLAR BEAR! Kiki gasped. "Connor, look!" Connor's face turned pale as he saw the giant paw print. "We have to be careful, Kiki," he said. His voice was quiet. "Polar bears look cute, but they are incredibly dangerous. They're stealthy hunters—fast, too. And their jaws are unbelievably powerful. Let's get back to the Beagle.

第四章当心——北极熊！Kiki气喘吁吁地说。 “康纳,看!”当康纳看到巨大的爪印时，他的脸变得苍白。 “我们得小心点，琪琪，”他说。 他的声音很平静。“北极熊看起来很可爱，但它们非常危险。 它们是隐形的猎人，而且速度很快。 它们的下颚无比有力。 让我们回到小猎犬号。

We might need to make a quick getaway." "How will we see it?" Kiki said, glancing around. "It's white, and so's the snow..." "A polar bear isn't actually white," said Connor. Kiki stared. "What do you mean?" Connor grinned at Kiki's expression. "Its strands of fur aren't white—they're transparent and hollow. That means the fur scatters the light, so it looks white." "That must be good for camouflage," Kiki said. Connor nodded. "And underneath their fur, their skin is black to absorb heat from the sun better. They're amazingly well adapted to life in the Arctic!" he said. "Good to hear," Kiki said a little wryly as she scrambled on to the snowmobile as fast as she could.

我们可能需要赶快逃走。” “我们怎么看呢？”琪琪环顾四周说。 “它是白的，雪也是白的……” “北极熊实际上并不是白色的，”康纳说。 Kiki盯着。“你是什么意思？”康纳对琪琪的表情咧嘴一笑。 “它的毛不是白色的，而是透明中空的。 这意味着皮毛会散射光线，所以它看起来是白色的。” “那一定是很好的伪装，”琪琪说。 康纳点点头。“在它们的皮毛下面，它们的皮肤是黑色的，可以更好地吸收太阳的热量。 它们非常适应北极的生活！”他说。 “很高兴听到这个消息，”琪琪有点挖苦地说，她尽可能快地爬上雪地摩托。

"Just don't tell me how well adapted their teeth are next." Connor climbed on behind Kiki. "After the crash, Dr. Mikkelsen must have run away to hide," he guessed. "But nobody could outrun a full-size polar bear." Kiki shivered. She hoped Dr. Mikkelsen had a good hiding place. She pressed the "START" button. The Beagle roared to life. "Where are we going to look?" Connor shouted over the sound of the engine. Kiki studied Dr. Mikkelsen's GPS tracker. The signal was strong and steady, some way off to the west of the crash site. She directed the Beagle away from the cliff, carefully skirting the polar bear prints. Soon they were driving toward a broad plain of ice that seemed to stretch forever. Kiki had never seen anywhere so empty. She

“只是不要告诉我接下来他们的牙齿适应得有多好。” 康纳爬到琪琪身后。 “坠机后，米克尔森博士一定是跑开躲起来了，”他猜测。 “但没有人能跑得过一只全尺寸的北极熊。” Kiki颤抖。她希望她的医生。 米克尔森有一个很好的藏身之处。 她按下“开始”按钮。 小猎犬号咆哮着复活了。 “我们去哪儿找？”康纳在引擎声中喊道。 琪琪研究了米克尔森博士的GPS追踪器。 信号强烈而稳定，在坠机地点以西一段距离之外。 她引导小猎犬号离开悬崖，小心翼翼地避开北极熊的脚印。 很快，他们就驶向一片广阔的冰原，那片冰原似乎永远延伸不下去。 琪琪从来没见过这么空的地方。 她

frowned at the coordinates on the Beagle's dashboard. "The signal says Dr. Mikkelsen should be nearby," she called to Connor behind her. "Can you see her?" "There's nothing out here," Connor called back.

对着小猎犬号仪表板上的坐标皱起了眉头。 “信号显示米克尔森博士应该就在附近，”她对身后的康纳喊道。 “你能看见她吗？”“外面什么也没有。”康纳喊道。

It was true. There was nothing in sight but the endless white horizon. Kiki put on the brakes. "I think it's time we called the Exploration Station," she said. The Beagle BEEPED in agreement. The sound echoed across the snow. Kiki pressed a button and a screen flickered to life on the Beagle's dashboard. "Hey!" said Tamiko, from the familiar black-walled surroundings of the Exploration Station. "How's the mission going?" Ollie appeared behind Tamiko. "Had a snowball fight yet?" he said. "We haven't had time for that," said Kiki. "We urgently need to find a research scientist who's disappeared. Her name is Dr. Mikkelsen. She had a snowmobile accident, but she didn't stay with the snowmobile and headed out here somewhere."

这是真的。除了一望无际的白色地平线，什么也看不见。 琪琪踩了刹车。她说：“我觉得是时候给探索站打电话了。” 小猎犬发出哔哔声表示同意。 声音在雪地里回荡。 琪琪按下了一个按钮，小猎犬号仪表盘上的屏幕闪烁起来。 “嘿！”多美子在探索站熟悉的黑墙环境中说。 “任务进行得怎么样了？”奥利出现在多美子身后。 “打雪仗了吗？”他说。 “我们没时间了，”Kiki说。 “我们迫切需要找到一名失踪的科学家。 她叫Mikkelsen博士。 她在雪地摩托上出了事故，但她没有留在雪地摩托上，而是去了这里的某个地方。”

"And there's a polar bear," Connor added. Leah appeared. "A polar bear?" she said eagerly. "Where?" "That's the trouble," said Kiki. "We don't know. Can you help us? The GPS tracker is telling us that Dr. Mikkelsen is nearby, but we can't see anyone." "We could search for thermal activity," Roshni suggested. "Astronomers use the

“还有一只北极熊，”康纳补充说。 利亚出现了。“北极熊？”她急切地问。 “在哪里?”“这就是问题所在，”Kiki说。 “我们不知道。你能帮助我们吗？ GPS追踪器告诉我们。 米克尔森就在附近，但我们看不到任何人。” “我们可以寻找热活动，”Roshni建议道。 天文学家使用
