[课时作业] [限时30分钟] Ⅰ.阅读理解 A (2022·渭南三贤中学高一期末)Anyone watching the Winter Olympics in Beijing, China over the last few days has seen man­made snow. Since the area gets little natural snow, the Winter Olympics took place on almost 100% man­made snow for the first time. This year's Winter Olympics were held in Beijing, China, and in two areas northwest of Beijing，Yanqing and Zhangjiakou. The areas get cold in the winter, but they don't get a lot of snow. That's because they're not far from the Gobi Desert, and are generally very dry. China took water from a reservoir (水库) which helped supply Beijing's drinking water and sent it to a nearby river. To carry the water to the mountains for making snow, China ran miles and miles of pipes. China says making the snow took about 49，000 gallons (185，500 liters ) of water. China hired a company called TechnoAlpin to create the snow. TechnoAlpin created man­made snow at several earlier Winter Olympics. For the snow in this year's Olympics, TechnoAlpin laid over 40 miles ( 64 kilometers ) of pipes and brought in hundreds of snow­making machines. With all equipment, making the snow for this year's Games took seven weeks. Man­made snow isn't the same as natural snow, which has more air and less water. Still, the advanced machines can make several different kinds of snow depending on what's needed for each sport. China says that the snow at this year's Winter Olympics was produced by using wind and solar energy. Man­made snow was used in the Winter Olympics in 2010 and 2014 because of warm weather. In the 2018 Games in PyeongChang, South Korea, approximately 90% of the snow was also made by machine. [语篇解读]　本文是一篇说明文，主要讲的是北京冬奥会运动赛场的人造雪的制造方法。 1．What is the first paragraph mainly about?
