一、基本保持稳定1.题型比例与分值今年的选择题由14个调整为12个,但立体几何选择题的个数并没有发生变化,仍为3个,只不过分值由去年的13分调整为15分.填空题、解答题的个数与分值都与去年一样,一个填空题,4分;一个有三小问的解答题,12分.这样,立体几何试题的总分数为31分,占20.7%,符合《考试说明》的规定.2.考查内容立体几何试题的考查内容与去年基本一致,选择题的三个小题考查的内容与去年一样,都是第二章多面体和旋转体的内容.填空题以考查第一章线面位置关系为主.解答题仍是以某一多面体为依托,考查线面位置关系的证明,角或距离的计算,只不过今年是两问证明,一问计算.
First, basically stable 1. Question proportions and scores This year’s multiple-choice questions were adjusted from 14 to 12, but the number of three-dimensional geometric multiple-choice questions did not change, still three, but scores from last year’s 13 points are adjusted to 15 points. Fill in the blank questions, the number of questions and scores are the same as last year, a blank-filled question, 4 points; a question with three small questions, 12 points. In this way, the total score of the three-dimensional geometry questions is 31 points, accounting for 20.7%, in line with the “Exam Description” provisions. 2. Examination content The content of the three-dimensional geometric examination questions are basically the same as last year. The contents of the three small questions of the multiple-choice questions are the same as last year. They are all the second chapter polyhedron. And the content of the rotating body. Fill in the blanks to examine the positional relationship of the first chapter. The answer is still based on a polyhedron, and the verification of the positional relationship of the line surface, the calculation of the angle or the distance, but this year is two Ask the proof and ask for a calculation.
