Unit 3 Period 2 课时练案 课文整体阅读(Reading)-【名师导航】2025-2026学年高中英语选择性必修第二册教师用书word（译林版）

本高中英语讲义以“基因组编辑”为核心主题，构建“词汇学习—长难句分析—阅读理解—批判性思考”的递进式学习支架。通过affect、contract等核心词汇的多义辨析及用法示例，结合课文长难句的断句指导与翻译训练，辅助学生夯实语言基础，再通过主旨题、细节题、态度题等阅读理解题型及开放性问题（如对“设计婴儿”的看法），实现从篇章理解到深层思维的过渡。 该资料突出语言能力与思维品质的协同培养，词汇部分通过教材原句实例强化语境应用，长难句分析提升复杂文本理解能力，开放性问题引导学生探讨科技伦理，培养批判与评价思维。课中助力教师分层引导学生从语言输入到输出，课后学生可借助词汇表、句型解析及问题提示自主复习，弥补语言知识与思维训练的盲点。

What consequences might it have? Philosophers，geneticists and government officials have all started to wrestle with such moral issues．We have to figure out how to keep the technology from running wild．This means putting appropriate controls in place to make sure that genome editing will work to our advantage．Without them，genome editing could be as dangerous as a car out of control． 4 / 4 学科网（北京）股份有限公司 $
