摘　　要：On a chilly morning,a relatively small piece of blanket can make us feel warm and cozy.A blanket doesn’t generate any heat of its own and it isn’t something you necessarily define as“hot”,so how does it keep you warm?Simply by trapping the body heat from escaping!A blanket in itself isn’t warm;all that it does is prevent the loss of our body heat.雪屋是由冰冷的雪做成的,但它却有很好的保暖功能,这是怎么做到的呢?这与雪的神奇特性和雪屋的结构有关。

关 键 词：SOMETHING necessarily TRAPPING
