摘要:
该高中英语课件聚焦“现在完成时被动语态”语法及科学职业词汇构词法,通过Activity 1对比主动与被动句实例,引导学生发现被动语态强调动作承受者的特点,结合4种使用场景总结规则,构建“识别差异-理解规则-情境应用”的学习支架,衔接语法改写、实验室情境描述及职业词汇(-ist/-ian后缀)拓展练习。
其亮点在于融合语言能力与思维品质培养,语法教学依托3D打印、医学应用等真实科技语境,任务型活动(如改写3D打印影响的句子、Dr Moore实验室报告)促进语言表达与逻辑推断;词汇拓展结合郭守敬、达尔文等中外科学家案例,渗透科学精神与文化意识,分层练习帮助学生构建语法网络,提升自主学习能力,教师可借情境任务实现语法与主题意义的深度融合。

Within the next 80 years, our lives may be changed beyond recognition by 3D printing. It has already affected many things in our lives, right down to the food we eat. For instance, some restaurants in London have served 3D-printed hamburgers to customers. But perhaps the most significant success that people have achieved to date is in medicine. They have made human body parts, including a beating heart, with 3D printing technology. And it is not just humans who are benefiting — in Brazil, people have given a new 3D-printed shell to a turtle injured in a forest fire!
