一、考情分析纵观近五年的高考命题,我们不难发现,高考对《现代生物科技专题》的考查方式是固定的,即以特定的背景材料为依托来组织命题,在此背景下,寻找各种工程技术的应用落点.“起点高,落点低”是选修3命题的主要特点,即考查的都是基本的概念、原理和基本的工程技术应用,重点考查对技术应用及分析,综合性强,但难度不大.二、考点整合考点一、基因工程1.基因工程的基本工具 First, test analysis Throughout the past five years college entrance examination proposition, we can easily find that the college entrance examination on the “modern biotechnology topics” test is fixed, that is, to rely on specific background materials to organize propositions, in this context , Looking for a variety of engineering application of the application. “High starting point, low landing point ” is the main features of the elective 3 proposition, that is to examine the basic concepts, principles and basic engineering applications, focusing on technology Application and analysis, comprehensive, but not difficult.Second, the test center integration test sites First, the genetic engineering 1. The basic tools of genetic engineering
