     Have you ever seen snow? Many people in the world have not. Some countries never have snow; some have

only a little on the tops of very high mountains. In the north of England, there is quite a lot of snow every winter,

but in the south of England, there is usually little.

     When a student from a warm country comes to England in autumn for the first time, he feels cold at first.

There are often dark clouds, grey sky and cold rain in England in autumn, and most students from warm

countries do not like this.

     But snow is different. Though it is cold, it is also beautiful. Perhaps, after several dark mornings, the student

wakes up one day, and there is a lot of light in his room. He thinks"Is it so late?" and jumps out of bed. But no, it

is not very late. He looks out of the window and there is the snow on the ground and on the houses and

everywhere. The light of his room comes from clean, beautiful snow.
