Unit 4 Body language Learning About Language Build up your vocabulary 课件-2025-2026学年高中英语人教版选择性必修第一册

该高中英语课件围绕“体态语”主题，聚焦构词法（转化、派生等）核心知识，从Wave、Nod等肢体语言词汇导入，通过视频引入构词法，再以定义、特点讲解为支架，结合表格对比（如名词-动词转化例句）和语境练习，构建“词汇感知-理论理解-应用实践”的学习脉络。 其亮点在于融合视频资源与表格化呈现（转化法拼写不变、词性改变特点，派生法前缀后缀作用），通过“一词多性”词义猜测（如book作动词“预订”）和语篇填空练习，提升学生语言能力（词汇运用）和思维品质（分析比较），同时强调查字典习惯培养学习能力。学生能在语境中掌握构词规律，教师可直接利用系统练习与理论讲解优化教学。

Unit 4 Body Language Learning About Language Learning objectives By the end of this section, you will be able to: Enhance your own vocabulary through learning about the different forms of the words; Understand the difference in meaning of words that are spelt the same based on their parts of speech or usage; Grasp and practise words in context; Get into the habit of looking up dictionaries during learning. Three ways of word formation: 构词法 1.转化 Conversion 2.合成 Compounding 3.派生/缀合 Derivation 4.缩略法 Abbreviation 5.截短法 Clipping Now, let’s watch a video about English word-formation. 1. 转化法(Conversion)：也叫 “零派生法”，（Zero Derivation）是英语中最简洁、最常用的构词法之一，核心定义是：不改变单词的拼写形式，仅通过改变其语法词性（如名词→动词、形容词→名词），从而产生新含义、形成新词的方法。 转化法的核心特点： 1.拼写不变：新词与原词的字母组合完全一致，无任何形式变化（这是与派生法、合成法的核心区别）； 2.词性改变：核心变化是语法功能的转换（如名词作动词、形容词作名词）； 3.语义关联：新词的含义通常与原词密切相关，多是原词语义的延伸或场景化应用（不会完全脱离原词本义）。 词（名词） 转化词（动词） 例句 book（书） book（预订） I need to book a flight to Beijing. water（水） water（浇水） She waters the flowers every morning. doctor（医生） doctor（诊治） He doctored the wounded soldier on the battlefield. park（公园） park（停车） Can I park my car here? email（邮件） email（发邮件） I’ll email you the report tonight. 原词（动词） 转化词（名词） 例句 run（跑） run（跑步；短途旅行） Let’s go for a run after dinner. look（看） look（样子；一瞥） She gave him a strange look. build（建造） build（建筑；构造） The new building is a modern build. win（赢） win（胜利） That’s a big win for our team. help（帮助） help（帮手；帮助） He’s a great help in the office. 2.派生(Derivation)：通过在基础单词（词根 / 词干）前添加前缀（Prefix）、或后添加后缀（Suffix），甚至同时添加前后缀，改变原词的含义、词性或语义色彩，从而构成新词的方法。 组成部分 定义 位置 核心作用 词根 单词的核心语义单元，承载单词最基本的含义（无词性） 单词中心 决定单词的核心语义（如port=“搬运”，vis=“看”） 前缀 附加在词根前的词缀 词根前 主要改变单词的含义（如 “肯定→否定”“时间→空间”），不改变词性（少数例外） 后缀 附加在词根 / 词干后的词缀 词根 / 词干后 主要改变单词的词性（如名词→动词、形容词→副词），可轻微调整语义（如褒义→贬义） 前缀 含义 例子 dis- un- 否定 dislike unhappy re- 再一次 retell pre - 事先，先前 prehistory sub- 向下 subway 后缀 含义 例子 -ist 一类人 journalist artist -ive ....的 creative active -ness 表名词 vastness darkness -al ...的 traditional natural Fill in the table with different forms of the words.
