Unit4 Safety first 第三课时Grammar time （课件）-2026-2027学年译林版(三起) 英语五年级上册

该小学英语课件围绕Unit4 Safety first主题，聚焦情态动词should/shouldn't的用法，通过Let's learn表格呈现主语与行为搭配，从零基础语法讲解过渡到选择题练习，再到Look and say看图判断，以Make a poster活动为学习支架，帮助学生逐步掌握语法知识。 其亮点在于结合“School safety”主题，通过情境化任务（如制作安全海报）和多样化练习（选择、看图说话、连词成句），提升学生语言能力（运用should/shouldn't表达安全规则）和思维品质（对比判断行为对错）。例如Look and say中“run”在教室和操场的不同表达，Make a poster整合10余项安全规则，助力学生在实践中巩固语法、培养安全意识，教师可直接使用结构化资源提升教学效率。
