Unit 3 Same or Different Section A (Grammar Focus) 教案 —— 形容词与副词的比较级（人教版八年级上册 2026-2027学年） 课题 Unit 3 Same or Different Section A (Grammar Focus) 学科 英语 年级 八年级 教材版本 人教版（2024） 课时 第 3 课时 课型 语法课 教学方法 归纳法、任务型教学法、情境教学法 教学用具 多媒体课件、黑板、粉笔 学情分析 八年级学生在前两节课中已经学习了人物比较的词汇和基本句型，对比较级有了一定的感性认识。本课是语法聚焦课，需要将感性认识上升为理性归纳，系统学习形容词和副词比较级的构成规则、常用句型和特殊用法。部分学生在多音节形容词比较级的构成（more + 原级）和不规则变化上仍存在困惑，需要通过大量例句和练习来强化。同时，"比较级表最高级"这一特殊用法对学生来说较为陌生，需要重点讲解和操练。 教学目标 ①语言能力：系统掌握形容词和副词比较级的规则变化和不规则变化；能熟练运用比较级的七种常用句型进行人物和事物的比较描述；能正确使用修饰比较级的副词（much, a little, far, even等）；理解"比较级表最高级"的特殊用法。②学习能力：通过观察例句归纳比较级的变化规则，培养归纳总结和演绎推理能力；通过对比练习提升语言运用的准确性。③思维品质：培养对比分析的逻辑思维能力，能从多角度运用比较级进行客观描述。④文化意识：了解英语中比较表达的文化习惯，如委婉比较和礼貌用语。 教学重难点 重点：形容词和副词比较级的规则变化（加-er/加-r/变y为i加-er/双写加-er/more+多音节）和不规则变化（good/well→better, bad/badly→worse, many/much→more, little→less, far→farther/further）；比较级的常用句型（A+比较级+than+B, Which/Who+比较级, A or B? 等）。难点：比较级与最高级的转换表达（no+比较级, 比较级+than+any other+单数名词）；修饰比较级的程度副词的正确使用；在真实语境中灵活运用比较级的各种句型。 一、教学过程 Step 1 Warm-up（热身导入）（3~5 min） 【教师活动】T: Good morning, class! In the last two lessons, we learned how to compare people using adjectives. Today we are going to focus on the grammar — the comparative degree of adjectives and adverbs. Let's first watch a short video to review what we know about comparatives. 【学生活动】Ss: (学生观看比较级相关视频，回顾已学的比较级用法) 【学生活动】Ss: I heard 'taller than', 'more beautiful than', 'runs faster than'... 【教师活动】T: Excellent! Today we will learn the rules behind these forms — how to form comparatives correctly and how to use them in different sentence patterns. 【过渡语】通过视频导入，同学们已经激活了关于比较级的已有知识。接下来我们进入Grammar Focus环节，通过观察例句来发现比较级的规律。 Step 2 Grammar Focus 3a（观察发现）（5~8 min） 【教师活动】T: Now open your books to Grammar Focus 3a. Read the sentences in the box carefully. Pay attention to the comparative forms of the adjectives and adverbs. Can you find the pattern? 【学生活动】Ss: I see 'taller', 'shorter', 'more outgoing' — some add -er and some use 'more'! 【教师活动】T: Very good observation! Now let's look through Section A and find more examples of comparatives. Work with your partner. 【学生活动】Ss: (学生在Section A中寻找更多比较级例句，如 better, louder, harder, longer, more outgoing 等) 【学生活动】Ss: We found: plays better, sing louder, work harder, taller, dances better, longer hair, more outgoing, as slim as, less serious. 【教师活动】T: Great! Why do some words add -er while others use 'more'? 【知识点】3a 观察归纳：比较级有两种构成方式——加-er和使用more。例句：taller, shorter, better, louder, harder, longer, more outgoing, slimmer, less serious。 【过渡语】通过3a的观察发现，同学们初步感知了比较级的两种构成方式。接下来我们系统学习比较级的规则变化和不规则变化。 Step 3 Grammar Rules（语法规则详解）（15~20 min） 一、核心定义与功能 【教师活动】T: The comparative degree is used to compare two people or things. The basic structure is: A + comparative + than + B. For example: Tom is taller than Jack. We can compare appearance, personality, ability and habits using comparatives. 【学生活动】Ss: So comparatives are for comparing two things, and 'than' is the key word! 【教师活动】T: Exactly! When we want to show how much difference there is, we can add words like 'much', 'a little', 'far' before the comparative. 【知识点】核心定义与功能：比较级用于两者对比，标志结构 A+比较级+than+B。用于对比外貌、性格、能力和习惯，常搭配 much, a little, far 等修饰。 三、规则变化 【教师活动】T: Now let's learn the rules for forming comparatives. There are five main rules for regular comparatives. Please listen carefully and take notes. 【学生活动】Ss: (学生记录规则变化的五种情况) 【教师活动】T: Rule 1: For most short adjectives, we add -er. tall → taller, short → shorter, fast → faster, hard → harder. Rule 2: For adjectives ending in -e, we just add -r. nice → nicer, large → larger, late → later. Rule 3: For adjectives ending in consonant + y, we change y to i and add -er. happy → happier, heavy → heavier, funny → funnier, early → earlier. 【教师活动】T: Rule 4: For short adjectives with a consonant-vowel-consonant pattern (one syllable, ending in one consonant after one vowel), we double the last consonant and add -er. big → bigger, hot → hotter, thin → thinner, slim → slimmer. Rule 5: For long adjectives (two or more syllables), we use 'more' + adjective. outgoing → more outgoing, beautiful → more beautiful, serious → more serious, hard-working → more hard-working. 【学生活动】Ss: So short adjectives add -er (with different rules), and long adjectives use 'more'! 【教师活动】T: Exactly! But be careful — some two-syllable adjectives can use both forms: clever → cleverer / more clever; quiet → quieter / more quiet. Also remember: adverbs follow the same rules. fast → faster, hard → harder, early → earlier, carefully → more carefully. 【易错提示】规则变化易错点 ① 辅音+y 变i加-er，不是直接加-er：happy→happier（不是happyer）。② 双写规则只适用于"元音+辅音"结尾的重读闭音节词：big→bigger（不是biger），但 small→smaller（不需要双写）。③ 多音节形容词（含双音节）用 more，不是加-er：outgoing→more outgoing（不是outgoinger）。④ 以-ly结尾的副词一律用 more：carefully→more carefully。 四、不规则变化 【教师活动】T: Unfortunately, not all adjectives follow the rules. Some very common adjectives and adverbs have irregular comparative forms. You must memorize these! 【教师活动】T: good and well → better. bad and badly → worse. many and much → more. little → less. far → farther or further. These are very common words, so you will see them all the time. Let's practise: This book is better than that one. She sings worse than before. He has more books than me. There is less water in this cup. She lives farther from school than I do. 【学生活动】Ss: good/well→better, bad/badly→worse, many/much→more, little→less, far→farther/further. We must remember these! 【重点强调】不规则变化记忆口诀 "好"good/well变better，"坏"bad/badly变worse，"多"many/much变more，"少"little变less，"远"far变farther/further。这五个是最常见的不规则变化，必须熟记！特别注意：good 的副词 well 的比较级也是 better；far 的两个比较级 farther/further 含义略有不同，farther 多指距离，further 多指程度。 五、常用句型 【教师活动】T: Now let's learn the seven common sentence patterns with comparatives. These patterns will help you express comparisons in different ways. 句型(1): A + be + 比较级 + than + B / A + 动词 + 副词比较级 + than + B 【教师活动】T: This is the most basic pattern. Tom is taller than Jack. She runs faster than me. He works harder than his brother. This pattern directly compares two subjects using a comparative adjective or adverb with 'than'. 【学生活动】Ss: Subject + be + comparative + than + object. Easy! 句型(2)(3): Which/Who + be/动词 + 比较级, A or B? 【教师活动】T: Pattern 2: Which is bigger, this box or that box? This one is bigger. Pattern 3: Who runs faster, Tom or Jack? Tom runs faster. These are questions asking for a comparison between two options. The answer should name one of the two. 【学生活动】Ss: Which/Who + comparative, A or B? We choose one to answer! 句型(4)(5)(6)(7): 其他常用句型 【教师活动】T: Pattern 4: A + be + the + 比较级 + of the two. Example: She is the taller of the two sisters. This means we are comparing two specific people, and A is the one with more of the quality. 【教师活动】T: Pattern 5: 比较级 + and + 比较级 / more and more + 原级. Example: It's getting colder and colder. She is becoming more and more beautiful. This shows something is increasing or changing over time. 【教师活动】T: Pattern 6: the + 比较级, the + 比较级. Example: The harder you work, the luckier you get. The more you read, the more you know. This shows a proportional relationship — one thing increases as another increases. 【教师活动】T: Pattern 7: A + be + 倍数 + 比较级 + than + B. Example: This room is three times larger than that one. This is used for numerical comparisons. 【学生活动】Ss: (学生记录七种比较级句型及其例句) 【知识点】七种比较级句型：(1) A+be+比较级+than+B / A+动词+副词比较级+than+B；(2) Which+be+比较级, A or B?；(3) Who+动词+副词比较级, A or B?；(4) A+be+the+比较级+of the two；(5) 比较级+and+比较级 / more and more+原级；(6) the+比较级, the+比较级；(7) A+be+倍数+比较级+than+B。 【判断技巧】句型(5)和(6)的区分 句型(5)"比较级+and+比较级"表示"越来越..."，描述事物自身的变化趋势，如：colder and colder, more and more beautiful。句型(6)"the+比较级, the+比较级"表示"越...越..."，描述两个变化之间的因果/比例关系，如：The harder you work, the luckier you get. 两者结构不同，含义不同，切勿混淆。 六、修饰比较级的前置词 【教师活动】T: We can add certain words before comparatives to show the degree of difference. much, a lot, far mean 'a big difference'. a bit, a little mean 'a small difference'. even means 'surprisingly more'. 【学生活动】Ss: much/a lot/far = 差距大；a bit/a little = 差距小；even = 甚至更。 七、比较级表最高级 【教师活动】T: Now here is a very special and important usage — using the comparative degree to express the superlative meaning. This is advanced, but very useful. Let me show you three patterns. 【教师活动】T: Pattern 1: no / nobody / nothing + 比较级. Example: Nobody is taller than him in our class. = He is the tallest in our class. I have never seen a better movie. = This is the best movie I have ever seen. No one runs faster. = He/She runs the fastest. When we use 'no/nobody/nothing + comparative', it actually means 'the most/the best'. 【教师活动】T: Pattern 2: 比较级 + than + any other + 单数名词. This is used when comparing within the SAME group. Example: China is larger than any other country in Asia. (China is in Asia, comparing with other Asian countries.) Tom is more hard-working than any other student in our class. (Tom is a student in our class.) 【教师活动】T: Pattern 3: 比较级 + than + any + 单数名词. This is used when comparing with a DIFFERENT group. Example: China is larger than any country in Africa. (China is NOT in Africa.) Tom is more hard-working than any student in Class Two. (Tom is NOT in Class Two.) Notice the key difference — 'any other' for same group, 'any' for different group! 【学生活动】Ss: (学生认真记录比较级表最高级的三种用法) 【易错提示】any other 与 any 的区别 比较级+than+any other+单数名词：同范围比较，加 other 排除自身（如 China is larger than any other country in Asia）。比较级+than+any+单数名词：不同范围比较，不加 other（如 China is larger than any country in Africa）。关键：主语是否属于比较范围。另外，no/nobody/nothing+比较级也表示最高级含义，如 Nobody is taller than him = He is the tallest. 【过渡语】通过系统学习，同学们已经掌握了比较级的规则变化、不规则变化、七种常用句型、修饰词用法和比较级表最高级的特殊用法。接下来进入Practice环节，通过练习巩固所学。 Step 4 Practice 3b（句型操练）（5~8 min） 【教师活动】T: Now let's do Activity 3b. Use the words in brackets to write questions and answers. Read the information carefully and think about what comparative form to use. 【学生活动】Ss: (学生阅读题目，思考如何用括号内的词写问答) 【教师活动】T: Let's check the answers. Number 1: Is Julie slimmer than you? No, she isn't. She is as slim as me. Notice — 'as slim as' means they are the same in slimness. This is not a comparative but an equal comparison. 【学生活动】Ss: Number 2: Are you as serious as your cousin? No, I'm not. I am less serious than he is. 'Less serious' means not as serious — the opposite of 'more serious'. 【教师活动】T: Number 3: Do you think Tom is smarter than Sam? No, I don't think so. Sam is as smart as Tom. 'As smart as' means they are equally smart. Number 4: Does Jack swim faster than Sally? No, he doesn't. He swims as fast as Sally. 'As fast as' means they swim at the same speed. 【学生活动】Ss: We also learned 'as...as' for equal comparison and 'less' for the opposite of 'more'! 【知识点】3b 答案：1. Is Julie slimmer than you? No, she isn't. She is as slim as me. 2. Are you as serious as your cousin? No, I'm not. I am less serious than he is. 3. Do you think Tom is smarter than Sam? No, I don't think so. Sam is as smart as Tom. 4. Does Jack swim faster than Sally? No, he doesn't. He swims as fast as Sally. 【过渡语】通过3b的练习，同学们巩固了比较级问答句型和as...as同级比较结构。接下来进行3c的读图比较练习。 Step 5 Practice 3c（读图比较）（5~8 min） 【教师活动】T: Now let's do Activity 3c. Look at the chart and compare Guangzhou and Vancouver. You will use the words in the box: large, small, much, warm, cool. Read the chart carefully first. 【学生活动】Ss: (学生仔细阅读广州和温哥华的数据图表，思考如何用给定词汇进行比较) 【教师活动】T: Let's check the answers. Number 1: The population of Vancouver was smaller than that of Guangzhou in 2024. Notice we use 'that of' to avoid repeating 'population'. 【学生活动】Ss: Number 2: In area, Guangzhou is larger than Vancouver. 【教师活动】T: Number 3: It rains more in Guangzhou than in Vancouver. Number 4: Guangzhou has a pleasant temperature in January. It is warmer than Vancouver in January. Number 5: Vancouver is cooler than Guangzhou in July. 【学生活动】Ss: We used the comparison words from the box: smaller, larger, more, warmer, cooler. 【知识点】3c 答案：1. smaller (that of 替代population) 2. larger 3. more 4. warmer 5. cooler 【过渡语】通过3c的读图比较练习，同学们学会了在实际语境中运用比较级进行城市对比描述。接下来我们学习本课的语言点。 Step 6 Language Points（语言点讲解）（5~8 min） 【教师活动】T: Let's study two important language points. First: population. When used as a subject for the total number, the verb is singular. Ask with 'What', not 'How many'. Describe size with 'large/small', not 'many/much'. Second: average can be an adjective (平均的), a noun (平均数), or used in the phrase 'on average' (平均来说). 【学生活动】Ss: (学生记录语言点：population 的用法、average 的词性和用法) 【过渡语】语言点讲解完毕。接下来进入当堂检测环节，通过练习来检验同学们对本课知识的掌握情况。 Step 7 Exercises（当堂检测）（8~10 min） 【教师活动】T: Let's do the exercises. First, four multiple choice questions about comparatives. Then four sentence completion questions. Please do them independently. 【学生活动】Ss: (学生独立完成单选和完成句子练习) I. 单项选择 1. My sister is ___ than me. A. hard-working B. more hard-working C. most hard-working D. as hard-working 2. This year's festival is ___ colourful than last year's. A. many B. more C. much D. most 3. Ella dances ___ than Emma, but Emma sings louder. A. good B. well C. better D. best 4. Emma always gets up ___ than Ella. A. early B. earlier C. earliest D. the earliest II. 完成句子 1. 她看起来比以前开心多了。 She looks _________________________ than before. 2. 这个班的平均年龄只有12岁。 The class has _________________________ only 12. 3. 读书越多，你越博学。 _________________________ you read, _________________________ you will be. 4. 城市的交通变得越来越便利。 The transport in the city is becoming _________________________. 【教师活动】T: Let's check the answers together. 【学生活动】Ss: 1. B. more hard-working 2. B. more 3. C. better 4. B. earlier 【教师活动】T: Good job! Now the sentence completion: 1. much happier 2. an average age of 3. The more...the more...wiser 4. more and more convenient. 【过渡语】通过当堂检测，同学们对本课知识的掌握情况已经显现。接下来我们进行课堂总结。 Step 8 Summary & Homework（总结与作业）（3~5 min） 【教师活动】T: Let's summarize. Today we learned: the comparative degree compares two things, with the structure A + comparative + than + B. We learned five rules for regular changes and five irregular forms. We studied seven sentence patterns and special usages for expressing superlative meaning. Don't forget the degree modifiers — much, a little, far, even! 【教师活动】T: For homework: Write five comparative sentences using different patterns we learned, and translate them into Chinese. Also preview the next lesson. 【学生活动】Ss: OK! We will write five comparative sentences with translations and preview the next lesson. 【过渡语】本节课系统学习了形容词和副词比较级的构成规则、常用句型和特殊用法。希望同学们课后认真完成作业，多做比较级造句练习，巩固所学。 二、板书设计（三栏式） Regular Changes（规则变化） Irregular（不规则变化） Sentence Patterns（常用句型） tall → taller nice → nicer happy → happier big → bigger outgoing → more outgoing good/well → better bad/badly → worse many/much → more little → less far → farther/further A + 比较级 + than + B Which/Who + 比较级, A or B? the + 比较级, the + 比较级 比较级 + and + 比较级 no + 比较级 = 最高级 Modifiers（修饰词）: much/a lot/far (差距大) a bit/a little (差距小) even/rather (甚至更) Superlative Form（表最高级）: no + 比较级 比较级 + than + any other + 单数 比较级 + than + any + 单数 Key Structure（核心结构）: A + 比较级 + than + B Unit 3 Grammar Focus Unit 3 Same or Different Section A (Grammar Focus) 三、教学反思 1.
