近年来,一类具有高中知识背景的试题,在中考中频频出现,且大多以阅读理解的形式出现,范围广、立意新、思路活、解题巧.这些试题的阅读量虽大,但难度并不大,只要考生认真阅读,仔细分析,把握新旧知识之间的联系,灵活处理,便能得出正确的答案.之所以出现这种现象,主要是因为初中许多知识是高中数学知识的生长点,而高中数学内容是初中有关知识的延伸与提高.
In recent years, a series of questions with senior high school knowledge backgrounds have appeared frequently in the middle school exams, and most of them have appeared in the form of reading comprehension. They have a wide range, new ideas, lively ideas, and clever solutions. Although the reading of these questions is large, it is difficult. Not so big, as long as candidates carefully read, carefully analyze, grasp the connection between old and new knowledge, and deal with it flexibly, we can get the correct answer. The reason why this phenomenon occurs is mainly because many knowledge in junior high school is the growth of high school mathematics knowledge. Point, and the content of high school mathematics is the extension and improvement of junior high school knowledge.
