A Happy Day
Winter came and the first snow began to fall. It was early Saturday morning. When I got up and looked out of the window, I saw trees, roofs and the ground all covered with snow. The world seemed to be a vast expanse① of whiteness②. How beautiful!“A heavy snow, a rich harvest.”Peasants must be very happy. I was happy, too, because…. Well, let me tell you.In the previous afternoon, when school was over, our teacher came into the classroom. “Shall we go to the hill and have a snow fight?”she asked us with a smile.“Good!”the whole class shouted cheerfully.
That`s why I was so happy in the morning.
When we got to the hill, we started making snow balls at once. Suddenly a snow ball hit me in the face. How cold! When I had made enough snow balls, I began to throw them at my“enemies”.
We threw snow balls at each other; we kept laughing and shouting. What great fun! We were children again. We did not stop enjoying ourselves until we could not see each other clearly for the dark.
On our way home, we were still talking about our snow fight. The wind was blowing hard, but we did not feel the cold. What a happy day!
