高考命题稳中有变,科技说明文的阅读是“稳定性”的试题。考生丢分比较严重,课文难度又往往偏低,指导与练习又往往不到位,师生陷于困惑。本文拟就命题特点、考查要点,以及复习指导谈一点意见,以探讨走出困惑的蹊径。文中涉及的93—95年试题,只标明题号,不附原题,以节省篇幅。 命题特点 (一)选材 一般是高科技知识的简有介绍,或科普短文。所涉及的科技知识一般是高科技领城的科研成果:93年介绍“生物降解(塑料的降解)”,94年介绍生物进化方面的新发现,95年是关于“地球以外人类文明”的探索。材料都是科技工作者最新提供的,涉足于高、新、深、尖
There is a change in the stability of the college entrance examination proposition, and the reading of scientific explanations is a “stability” test. The scores of the candidates are more serious, the difficulty of the texts is often low, and the guidance and practice are often not in place. Teachers and students are puzzled. This article intends to discuss some aspects of propositional features, examination points, and review guidance to explore ways to get out of confusion. The 93-95 test questions involved in the text only indicate the title number, and the original question is not attached to save space. Propositional Features (1) Material selection is generally a brief introduction of high-tech knowledge, or a popular science essay. The scientific and technological knowledge involved is generally the scientific research achievement of the high-tech city: the introduction of “biodegradation (degradation of plastics)” in 1993, the new discovery of biological evolution in 1994, and the exploration of “human civilization outside the earth” in 1995. . The materials are all provided by the scientific and technological workers and they are involved in high, new, deep and sharp.
