1. The college entrance examination questions in different provinces are different, and the scores of solid geometry are also different. According to the examination questions in previous years, solid geometry mainly examines the relationship between points, lines and surfaces, with cones in the majority and lines and surfaces in the majority. Most of them should investigate the combination of cone or cylinder and sphere, paying special attention to three views. There is little difference in the difficulty between liberal arts and science examination questions, but the liberal arts topic is slightly simpler. Liberal arts and science are two small questions (a multiple-choice question, a fill-in-the-blank question or two multiple-choice questions) and a big question, with 5 points for a small question and 0/2 points for a big question, and 22 points for * * *.

2, solid geometry preparation strategy.

First, we should have the concept of space. Always regard three-dimensional graphics as plane graphics, can't draw straight views and three views, and can't figure out the relationship between points, lines and surfaces of spatial graphics, so there is no way to do three-dimensional geometry problems. The physical model can be compared with the direct view to improve the spatial imagination of candidates.

Second, consolidate the basic knowledge. The main problem of solid geometry is the positional relationship between points, lines and surfaces, which should be described by angles and distances. There are three kinds of angles in space (dihedral angles formed by lines, lines and planes) and eight kinds of distances (distance between two points, distance between points and straight lines, distance between points and planes, distance between parallel lines, distance between different planes and straight lines, distance between lines and planes, distance between two points on a sphere).
