理科综合题常从社会热点与科技前沿说起,分步或分类设问,不像单学科题.按学科知识体系循序递进,每道题不一定有“学科核心”.学生答题时不要先考虑“学科划分”,要认真读题,当作科普问题求答.“多想科学,少想学科”,将会使你从实际出发,联想解题.左右逢源.下面以DNA为背景材料,作一点探讨. The science synthesis questions often start from the social hotspot and the frontier of science and technology, step by step or classify and ask questions, unlike single subject questions. According to the subject knowledge system progressively, each question does not necessarily have “subject core”. Students should not answer questions first Considering “discipline division”, you must read questions carefully and ask questions as science questions. “Think science more and think less about disciplines” will enable you to start from reality and think of solutions. Right and left are the sources. The following uses DNA as background material. A little discussion.
