[Q]: Article: Our first winter in Canada was the happiest we have experienced. We were living in the countryside then and had just arrived from Hong Kong that autumn. One evening in mid December snow began to fall. When we looked out of the window and saw that it was snowing, we all cheered. It was the first snow we had ever seen and we were excited. We could hardly wait for the snow to stop so that we could go out to play. Next morning when we woke up, it was still snowing. We switched on the radio and learned that more than ten inches of snow had falled during the night and that since the roads were blocked there would be no school that day. We jumped up and down for joy and begged mother to let us go outside to play in the snow. She said we could go out after breakfast if we dressed ourselves warmly and promised to come back as soon as we felt cold. When we went out, the snow had almost stopped. The roads , paths, gardens, and playing grounds were all hidden under a white blanket of soft snow. It was the most beautiful sight we had ever seen. Just then, we saw some neighbour's children coming out to play. We ran over to join them. Together we built a snowman and a snow house. After that, we took turns sliding down a hill on a large piece of cardboard. We were having so much fun when supper time came. Mother almost had to force us to go in and eat.

And they work hard to become well-known during the summer. The musicians and directors are experts who come from the best orchestras and operas in the country during their vacations. They enjoy working there because they like to live in Santa Fe, which is near both the mountains and the desert. It is very beautiful there in summer. The state government of New Mexico advertises the Santa Fe Opera in newspapers all over the country, and a great many tourists come to New Mexico because of the opera ,Still ,most of the audience does come from Santa Fe and other nearby cities. And all the seats in the theater are sold for every show. There is only one thing that some people do not like about the Santa Fe Opera, and that is the cold weather .Because the theater is open, performances cannot start before it gets dark at nine o'clock in the evening, and then the mountain air becomes very cool.
