奇特的窗玻璃

冬天到了，天气渐渐冷了起来。雪花漫天飞舞，给大地铺上了一层雪白的地毯。

When winter comes, it's getting cold. Snowflakes are flying all over the sky, laying a white carpet on the earth.

小熊穿着一身厚厚的棉袄来到小湖边一看，湖面上结着一层厚厚的冰雪。小熊看见冰既漂亮又透明。

Wearing a thick padded jacket, little bear came to the little lake to have a look. There was a thick layer of ice and snow on the lake. The little bear saw that the ice was beautiful and transparent.

于是，小熊用小刀割下了一块冰，想把冰当玻璃，透明闪亮真美丽啊！后来，小熊把冰带回了家。它把冰安在窗框上，然后，小熊开始生火做饭了。火越烧越旺，屋子里越来越暖和。

So, the little bear cut off a piece of ice with a knife. He wanted to use the ice as a glass. How beautiful it is to be transparent and shiny! Later, bear brought the ice home. He put the ice on the window frame, and then the little bear began to make a fire and cook. The fire grew hotter and hotter, and the room grew warmer and warmer.

咦？玻璃怎么会滴水呀！后来，小熊终于明白了，原来呀，屋内的温度升高了，屋外的温度低，所以冰会化成水。

Why? How can glass drip! Later, the bear finally understood that the temperature inside the house increased and the temperature outside the house was low, so the ice would turn into water.
