形势在发展,时间在疾驶。今年十二月二十二日,是我国人民粉碎“四人帮”后,迎来的第二个“冬至”日。地球绕太阳公转,同时又绕地轴自转,地球的公转和自转,导致了一年四季的变化和昼夜的更替。每年冬天,太阳移向南半球,北半球受到的阳光是斜射的,照到阳光的时间也短。“冬至”这一天,北半球各地正午时太阳的高度最小,白天时间最短,黑夜时间最长。
The situation is developing, the time is running. December 22 this year marks the second “Winter Solstice” day ushered in after the Chinese people crushed the “gang of four.” The earth revolves around the sun and at the same time rotates about the earth’s axis. The revolution and rotation of the earth lead to the change of the year and the change of day and night. Every winter, the sun moves to the southern hemisphere, the sunlight in the northern hemisphere is oblique, and the time it takes to sunshine is short. On the “winter solstice” day, the height of the sun is the lowest at noon in the Northern Hemisphere, with the shortest daytime and the longest nighttime.
