高考理科综合能力测试中化学计算试题常用选择、填空、简答、全过程计算等基本题型,与过去3+2单科化学卷不同的是,“3+X”理科综合测试中化学计算题的难度大大降低,加强计算能力考查(分值约占试卷化学部分的19％～29％),题型呈现多样化特征。高考通过计算题的形式考查学生对化学概念、化学理论、元素化合物、有机化学等知识的理解、掌握情况及思维的敏捷性、逻辑性、灵活性和创造性。现释例说明。
In the comprehensive test of science in the college entrance examination, the basic questions such as selection, filling in the blank, short answer, and whole course calculation are used in the chemistry test questions. The difference from the previous 3+2 single-chemistry chemistry roll is that the “3+X” chemistry test questions in chemistry The difficulty is greatly reduced, and the calculation ability is enhanced (the score accounts for approximately 19% to 29% of the chemical part of the test paper), and the questions are diversified. The college entrance examination examines the students’ understanding of the concepts of chemistry, chemistry theory, elemental compounds, and organic chemistry, and grasps the agility, logic, flexibility, and creativity of the students in the form of calculation questions. The explanations are now explained.
