通过对2011年“华约”七校自主招生试题第5题的分析,提出原题选项设计欠妥。并从命题规范的角度进行修正,追根溯源试题为俄罗斯中学物理竞赛试题改编而成。 Through the analysis of the fifth question of the self-enrollment questions of “Seven Schools” in 2011 “Hua Jiao”, it is suggested that the design of the original question is not properly designed. And revised from the perspective of propositional norms, tracing the source for the Russian high school physics contest adapted from the test questions.
