在 2 0 0 4年全国各省市中考数学试卷的几何解答题中 ,抽象的逻辑推理论证问题的难度普遍有所降低 .而探究性开放性问题的数量明显有所增多 ,且这类问题的文字表述大都较长 ,在总的题干之下 ,多个小题层层推进 ,环环相扣 ,形成了一个长长的问题链 .要完整、准确地解答这类问题 In the geometric answer questions for the mathematics examination papers of the provinces and cities across the country in 2004, the difficulty of the abstract logic in the theoretical evidence problem has generally been reduced, and the number of exploratory open questions has increased, and the number of such questions has increased. Most of the statements are long. Under the general title, several small topics are pushed forward and linked together to form a long problem chain. To solve such problems in a complete and accurate manner
