《高中地理》第一章中有一段“(地球)公转的轨道和周期”的内容,文字不多,插图仅有一幅。但近年来高考地理试题中屡次在此设题,不能不令人寻味。这段课文所牵涉的知识内容可谓“包罗万象”。通过多角度设题,可以考查学生对地球公转速度、太阳直射点、太阳高度角、昼夜长短,南北半球季节等知识的掌握程度;也可以考查有关全球海陆气压状况、海陆等温线分布、主要气团活动、地域天气或气候特征等基础识识;还可以考查有关河流补给与汛期、海洋航运与洋流
The first chapter of “Geography of High School” contains a section of the orbit and cycle of the “(Earth) revolution,” with only a few words and only a few illustrations. However, in recent years, many questions have been asked in the geographical examination questions in the college entrance examination. The content of the knowledge involved in this text can be described as “all-inclusive.” Through multiple angles, you can examine students’ knowledge of the speed of the Earth's revolution, the direct sun's rays, the elevation angle of the sun, the length of the day and night, and the seasons of the northern and southern hemispheres. You can also examine the global air and sea pressure conditions, the distribution of land and sea isotherms, and major air masses. Basic knowledge of activities, geographical weather, or climate characteristics; can also be used to investigate river replenishment and flood seasons, ocean shipping, and ocean currents
