Unit 4 课时5 Section B Vocabulary in Use（情境教学课件）英语新教材人教版九年级上册

该初中英语课件围绕“如何提升记忆力”展开词汇教学，核心知识点为常见词缀构词规则及重点词汇句型。课堂导入通过观看“猫咪记忆”视频引发兴趣，结合复习已学词缀（如-ful、un-等）搭建学习支架，引导学生用re-、-ion等词缀生成新词，建立词汇网络。 其亮点在于采用任务型词汇教学，结合词缀构词法（学习能力）和语境应用（语言能力），如2a用词典从“act”“forget”等中心词生成衍生词，2c通过动物记忆语篇填空应用短语。帮助学生自主拓展词汇、提升语境运用能力，教师可借助系统活动设计提高教学效率。

猫的记忆有多久？猫是不是根本不会想主人好问题？经常有人说猫太独立，没有感情。事实上，猫要忘记你可能需要十年更久。想知道这一点，你得先了解猫的记忆系统。有人问，猫这么小一脑袋，还有记忆系统，这必须有啊，而且还得分长期记忆和短期记忆，长期记忆远超人的预估能有16小时左右，就是觉得这也没多长，看看隔壁狗，短期记忆五分钟被训一顿还傻乐，甚至可能训到一半都忘了自己为啥被训不过猫在联想机这一块比不过狗子就是为什么狗能学会指定猫就很难有人又问，猫的长期记又有多久那是针灸用维基百科引证猫的长期记忆超过十年如果猫咪对你有感情，可能这一生都不会忘记你这是叫空间的猫咪被主人一直从小养到大但因为主人生病，他不得不被送养给其他人然而时隔两年之后的实验中，在一堆陌生人和主人的录音中，对陌生人呼唤无动于衷的他，却在听到主人呼唤时，马上竖起了耳朵寻找主人。You can对你在猫咪心中可能远比。你想象的还重要。毕竟你的一生可能不止一只猫咪，他们的一生只有你。 如果你知道pressure是压力，那么一分钟后你将学会这15个单词，准备好了吗？首先它们都有一个共同的核心词跟press，它的核心含义就是暗合压。而X这个前缀有向外的意思，把心里的想法用力向外挤压出来，这就是express，表达、表露。再加上形容词后缀，就变成了expressive，富有表现力的看，表示一起，把东西都压到一起，这就是compress，压缩，压紧。再加上形容词后缀，就变成了compressible，可压缩的sup，表示在下面，把东西死死压在脚下，这就是surprise，压制控制再加上形容词后缀就变成了suppressive，压制性的M表示向内，把一个画面深深的向内压进你的脑海里，这就是impress，留下深刻印象再加上形容词后缀就变成了impressive，令人印象深刻的奥皮，表示反向，一大股势力反向冲着你压过来，这就是a press压迫压再加上形容词后缀就变成了oppressive，压迫的沉闷的地表是向下，如果是心情被向下压，那就是沮丧，如果是经济被向下压，那就是萧条再加上形容词后缀就变成了depressive抑郁的V表示挽回。眼泪快掉出来了，又硬生生压回去。这就是repress、克制、压抑，再加上形容词后缀，就变成了repressive、压制的、益智的，最后加上名词后缀诱饵。那种压在你身上的无形重量就是pressure、压力、压强。你学会了吗？死记硬背不如掌握底层逻辑，关注我，一起努力进步。 课型：词汇课 Unit 4 Our Memory 课时：Vocabulary in Use Section B How can we improve our memory? 在语境中感知常见词缀的构词规则，理解本节课重点词汇与固定短语的词性、释义以及使用语境，读懂词汇在句子和简短语篇里的含义，建立系统的词汇认知。（学习理解） 01 把学到的构词技巧和重点表达运用到真实话题交流当中，自主借助词缀积累课外生词，围绕记忆学习相关话题发表自己的观点，养成高效记词习惯。（迁移创新） 03 运用词缀知识拓展衍生词汇，结合时态、主谓一致调整词汇形式完成填空练习；借助核心短语造句、完成情景练习，在句子层面完成词汇的有效输出。（应用实践） 02 教学目标 01 Lead-in 3 Let’s watch and learn.
