近年来国内外数学竞赛和考试命题的一些动向值得注意,如选择题明显增多,在不脱离“双基”的前题下灵活度加大,高等数学的一些思想逐渐渗入,问题提法新颖多样等等,这都要求解答者对基础知识要融汇贯通,运用自如,通晓一般解题术, In recent years, some movements in the math contests and examination propositions at home and abroad are worth noting. If the number of multiple-choice questions has increased significantly, the degree of flexibility will increase under the premise that the “double bases” will not be separated. Some ideas of advanced mathematics will gradually infiltrate, and the problems will be novel and diverse. And so on, all of these require that the solver must integrate basic knowledge, apply freely, and be familiar with general problem solving techniques.
