Their population has dropped sharply in recent years. Human activities bring them serious trouble. People cut down trees and use harmful chemicals. These actions destroy their natural home and kill the plants that monarch caterpillars feed on. Luckily, people have taken action to save them. Scientists record their migration and work to make sure there are enough plants for them to live on. More and more people are raising public awareness of protecting this lovely creature. Every small effort matters. We should learn more about monarch butterflies and tell our friends about their difficult situation. Let’s refuse harmful chemicals and plant more milkweed for them. If we all take action, these wonderful butterflies will fly freely in nature for many years to come. Design a simple English poster slogan for protecting wild migrating animals. Draw simple pictures and write 3‑5 English sentences on your poster. ●分层设计，照顾不同层次学生；实现知识迁移，从阅读走向书面输出。 板书设计 必修第一册Unit 5 Into the Wild Starting out & Understanding ideas Text structure（说明文） 1. Lead‑in：phenomenon（Monarch butterflies migration） 2. Process：when / where / why 3. Threats：human activities 4. Appeal: protect wildlife Think: Man and nature (live in harmony) 教学反思 优点：教学设计遵循英语学习活动观，以主题意义引领课堂，从视频导入到读、思、说，活动层层递进，完整落实科普说明文阅读教学 缺点：科普文本包含较多长难句与专有名词，部分基础薄弱学生阅读压力较大；课堂时间有限，长难句拆解讲解不够充分。 改进：课前布置预习任务，提前扫清部分专有名词障碍；细读环节挑选 2‑3 个典型长难句进行句法拆解，降低理解难度。 1 / 11 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $
