Unit 2 Teenage Problems (Grammar)课件2026-2027学年译林版英语九年级上册

该初中英语课件聚焦九年级译林版Unit 2语法模块，核心讲解if/whether和疑问词引导的宾语从句。课堂以“作业问题”讨论导入，通过改写yes-no疑问句（如“是否需完成所有作业”）引出if/whether用法，再过渡到疑问词引导的从句（如“同学如何看待外貌”），以例句分析、规则总结和人称/时态变化小贴士搭建学习支架。 其亮点在于情境化与任务型结合，用青少年真实问题（如考试焦虑、朋友矛盾）激发兴趣，通过改写、对话填空到写作产出的分层练习，培养学生语言能力（从句理解与表达）和思维品质（规则归纳与逻辑运用），总结融入“逢山开路，遇水搭桥”等中英文谚语渗透文化意识。学生能在实践中掌握语法，教师可借助清晰结构提升教学效率。

When meeting mountains, build roads; when crossing rivers, build bridges. 逢山开路，遇水搭桥。 Summary of this lesson We have learned to use the two object clauses: Object clauses introduced by if/whether Object clauses introduced by question words to express a yes-no question and a wh- question after verbs such as ask, see, wonder, be not sure, find out and so on. The word order in the clauses like these should be the same as that in a statement. We have also learned about how to describe our problems clearly. I often wonder if I have too much homework. I ask myself whether I can finish tasks quickly. I don’t know how I can reduce study stress, and I want to find out when I can have free time for my hobbies. Homework Must do: Write about one of your problems, using object clauses introduced by that, if/whether and question words. Optional: Use the internet to check your sentences and learn more useful expressions to talk about your problems. 24 $
