外研版 (2019)必修 第三册Unit 6 Disaster and hope教学设计

这是一份外研版 (2019)必修 第三册Unit 6 Disaster and hope教学设计，共5页。教案主要包含了设计意图等内容，欢迎下载使用。
本课时涉及的部分是语言知识运用，包括语法“Ellipsis——省略”，Types f natural disasters和 Extreme weather cnditins三部分。
语法“Ellipsis——省略”讲解省略结构的原则及其用法。
Types f natural disasters介绍了几种常见的自然灾害，包括：干旱、台风、暴风雪、海啸、野火、雪崩和地震。通过介绍这几种自然灾害，让学生进一步认识到灾害天气的影响和破坏性。
Extreme weather cnditins部分主要以听、说的方式讲述了人类从数千年前就尽力预测天气状况，从商朝的甲骨文到西方亚里土多德的天气形成理论，再到现在的卫星和计算机技术的运用，使天气预报一步步精准化。

【设计意图】该部分基本按照课本顺序设置活动，由浅入深，逐层加深难度，锻炼了学生读、听、写、说的能力。首先，通过读 “Did Yu knw？”部分，了解人们对天气的预测情况。然后，通过听录音，先解决浅层的理解，再记录听力的要点，完成 Activity 7和8。接下来是说的环节，通过语言输入，学生头脑中对自然灾害、极端天气状况有了初步认识，同时掌握了该部分常见词汇和句型，再仿照上述内容进行对话练习。整个环节内容不多，但环环相扣，遵循了语言的认知规律，设置科学、合理。
