2012—2013年高考理科综合能力测试(新课标I)化学试卷中选择题7小题,赋42分。对比表1、表2,可以看出化学选择题的命题,考查内容较为稳定,突出考查了学科的主干知识、基础理论和基本技能。一、存同求异,难度提升两年选择题内容有重现的内容,但具体考查内容又不尽相同,如关于元素周期律的考查,2012年侧重于元素推断及元素周期律,而2013年却侧重于元素推断及微粒对平衡的影响。如,关于化学平衡的考查,2012年的落脚点为水的电离平衡,而2013年则关
2012-2013 college entrance examination science comprehensive ability test (New Course I) chemistry papers in the multiple choice 7 small questions, assigned 42 points. Comparing Table 1 and Table 2, it can be seen that the propositions of the chemical multiple choice questions are relatively stable and highlight the subject knowledge, basic theory and basic skills. First, the coexistence of different, more difficult to upgrade the contents of the two-year multiple-choice questions content, but the specific content of the test is not the same, such as the examination of the periodic law of the elements, in 2012 focused on element inference and periodic law of the law, and 2013 Years are focused on the elements of inference and the impact of particles on the balance. For example, on the test of chemical equilibrium, the 2012 target is the ionization equilibrium of water, while in 2013 it was off
