Unit 5 Safety Lesson 3成都市龙江路小学高燕教材分析：本单元的话题是安全，共7个课时。本课为第三课时，呈现了 10条生活中常用的安全 规则，并在其中呈现核心功能句型:祈使句Don't. Ifs dangerous.以及Please . . Ifs safe. 这些规则还渗透了情感教育：在生活中遵守安全规则，提醒学生提高安全意识。通过本课的学习，学生能够大致了解生活中常用的安全规则，并能熟练运用分辨事情 是否安全，能否去做。实现从理解语言到实际运用语言的过程。学情分析：本课所面向的是已有三年英语基础的小学四年级学生，他们已经在三年级时通过I can和lean3表达过什么事情能做，什么事情不能做。而在这节课上，学生会以此为基础, 用Dont.和please来表达什么事情安全可以做，什么事情危险不能做。并且学生经过三年 的英语学习，已经具备了一定的英语听、说、读、写的能力，养成了较好的学习习惯，并掌 握了一定的自主学习，合作学习的学习策略。教学目标：1 .语言能力：学生初步感知祈使句；学生能够运用以下祈使句进行自主表达：1. Don't . . Ifs dangerous. 2. Please . It's safe；2 .学习能力：学生采取小组探究合作式的策略，来完成梳理不同场景中的安全规则；在以安全为主 题的学习中，主动探寻、讨论分享生活中安全的做法和不安全的行为。3 .思维品质:在充分解读学校和街道上的安全规则后，学生通过小组探究，梳理出不同场景中的安 全规则，并用不同的方式进行表述，实现英语多元思维的培养目标。4 .文化品格：通过对书中安全规则的解读，以及各组对于各自场景中安全规则的梳理，让学生J'解生 活中常见的安全规则，提醒学生遵守安全规则，提高安全意识和自我保护意识。教学重点：通过解读学校和街道上的安全规则，熟练运用核心句型：1. Don't . . It,s dangerous. 2. Please . It,s safe.来描述不同情景中的安全规则。教学难点：学生在了解街道和学校的安全规则后，小组合作梳理，并书写其他场景下的安全规则。教学过程：一、Warm up1. Greeting（设计意图：课前寒喧，拉近师生距离）2.
