初中数学共有170个左右的知识点,中考数学试题中所考查的知识点一般有120个左右,约占70％。这就是说,对各章节的重点知识的考查,其覆盖面十分广泛。中考试题与我们平时所学习的数学课本密切相关,一般地讲,50％左右的试题源于课本。为了帮助同学们在学好课本知识的同时,提前了解和熟悉中考数学命题,把握关键,提高能力,增强信心,本刊编辑部将有计划地向大家介绍各章节的中考数学考点,并辅以配套自测题(例题与习题均选自近年来各省市中考题)。
There are about 170 knowledge points in junior high school mathematics, and there are about 120 knowledge points examined in mathematics questions in the examination, accounting for about 70%. This means that the examination of the key knowledge of each chapter covers a very wide range of coverage. The examination questions are closely related to the math textbooks that we usually study. Generally, about 50% of the questions are from textbooks. In order to help the students to understand and familiarize themselves with the mathematics proposition in advance, grasp the key, improve their abilities, and enhance their confidence while learning the textbook knowledge, the editorial department of the periodical will systematically introduce each chapter to the mathematics test center for the senior high school entrance exam, supplemented by matching facilities. Self-test questions (examples and exercises are selected from the examination questions of provinces and cities in recent years).
