When you’re all comfortable and warm, watching the snowflakes pile up outside, you might wonder, what about the poor animals? No fire. No cocoa. No blankets.【小题1】 Well, it’s really people who aren’t designed to live in cold climates.【小题2】 Geese have built-in down comforters. Bears have fur coats. Robins just fly south. But look at people. No fur. No feathers. No fair! And not everyone can jet off to Florida when it snows. 【小题3】Mainly, our big brains. Still, it’s taken us a long time to figure out how to cope with cold weather, and along the way we’ve borrowed a few tricks from the animals, too. When you put on a jacket, you feel warm. Why? Because your jacket traps the heat your body produces. Your body uses the food you eat as fuel to stay warm.【小题4】 Active muscles burn more fuel and produce more heat. That’s why you shiver when you’re cold. By shivering, your body is doing its best to get your muscles moving and warm you up. 【小题5】 Even in the coldest weather, your brain needs lots of warm blood. That’s one reason why your feet and hands get cold --- your body is sending heat to your brain. If you put on a hat, you will find that your feet and hands get warmer.
A．How do they stand it?
B．It can no longer trap a layer of warm air.
C．If you run or jump around, you feel even warmer.
D．So what do people have to help beat the cold?
E. Animals have lots of cool ways to survive the winter. F. That’s because water carries heat away from your skin. G. The most important part of your body to keep warm is your brain.
答案：【小题1】A 【小题2】E 【小题3】D 【小题4】C 【小题5】G
试题分析：本文是一科普文，主语介绍了人类是怎样抵御寒冷的，此文较简单，主要联系上下文语境即可。 【小题1】A。根据上文：当我们在温暖的房间里，而户外寒冷飘着雪花，那些动物们没有火，可可，毛毯自然会想到How do they stand it。故填A。 【小题2】E。联系下文鹅有羽绒被，熊有毛皮大衣，知更鸟飞到南方。可知该句Animals have lots of cool ways to survive the winter为总说。故填E。 【小题3】D。联系下文人类抵御寒冷是通过我们的大脑想出来的，借鉴了动物的做法可知该句为So what do people have to help beat the cold?起引起下文的作用。故填D。 【小题4】C。联系下文肌肉运动燃烧脂肪制造热量可知If you run or jump around, you feel even warmer.故填C。 【小题5】G。联系下文：即使在最冷的季节，你的大脑需要许多温暖的血液。可知The most important part of your body to keep warm is your brain.故填G。 考点：考查科普类阅读。
