摘　　要：根据伯努利原理对北京市2020年普通高考物理第14题进行深度剖析,利用伯努利方程详细分析由于空气动力学原理造成篮球下落轨迹偏离竖直方向的本质原因.并试图从该试题的命题视角窥视高考改革的导向或高考试题的命题走向.According to Bernoulli′s principle,it conducts an in-depth analysis of the physics question 14 of the 2020 Beijing General College Entrance Examination,and uses Bernoulli′s equation to analyze in detail the essential reason why the falling trajectory of basketball deviates from the vertical direction due to the principle of aerodynamics.And try to see the direction of the reform of the college entrance examination or the trend of the proposition of the college entrance examination questions from the perspective of the proposition of the test questions.

关 键 词：马格努斯效应 伯努利原理 伯努利方程 空气动力学
