学情分析 学生在七年级已学习形容词基本用法，能简单描述人物特征，但在听力中快速捕捉比较信息、运用比较级句型及as...as...结构进行人物对比方面仍有困难。本课通过学校音乐节话题的听力训练和口语比较活动，帮助学生掌握比较级的初步运用。
教学目标 语言能力：运用比较级句型和核心词汇描述并比较人物的外貌和性格特征。 文化意识：通过学校音乐节和双胞胎话题，理解个体差异的多样性。 思维品质：分析对话中的人物比较信息，归纳比较级句型结构。 学习能力：运用预测-听取-核对的听力策略，提取人物特征比较信息。
教学重难点 重点：核心词汇9个（shy/lazy/loud/outgoing/hard-working/perform/alone/solve/flute）、比较级句型（A is taller than B / A plays better than B）、反义词配对。 难点：听力中快速捕捉人物比较信息并完成1b/1c/1d任务、as...as...句型的理解和运用、比较级中形容词和副词的正确形式变化。
图3-1 学习目标（词汇与比较级运用）
一、教学过程
Step 1 情景导入 Look and share（3~5 min）
【教师活动】T: Good morning, class! Today we start Unit 3 — Same or Different Look at the photo. What is the possible relationship between the girls in the photo What do they have in common And how are they different from each other
【学生活动】Ss: Students look at the photo and discuss the three questions in pairs. They identify the girls as twin sisters and note their common features and differences.
Look and share 讨论问题：
1. What is the possible relationship between the girls in the photo — They are twin sisters.
2. What do they have in common — Looks, heights and school uniforms.
3. How are they different from each other — The girl on the left is outgoing and likes playing table tennis. The girl on the right is shy and enjoys reading.
图3-2 Look and share 情景导入（双胞胎姐妹）
【教师活动】T: Good! The left girl is outgoing and the right girl is shy. 'Outgoing' means friendly and liking to meet people. 'Shy' means being afraid to speak in front of people. These two words are opposites. Can you think of other opposite words
【学生活动】Ss: Students learn the words 'outgoing' and 'shy', and brainstorm other opposite adjective pairs they already know, such as tall/short, big/small.
【知识点】情景导入：通过Look and share观察双胞胎姐妹图片，激活学生关于人物特征比较的背景知识，引出outgoing/shy等核心词汇
【过渡语】同学们已经能描述人物的不同特征，现在让我们通过一首歌来感受比较级的用法。
Step 2 Lead in 听歌填空（5~7 min）
【教师活动】T: Now let's listen to a song. Listen carefully and fill in the blanks. Pay attention to the ending of each adjective — they all have '-er' or 'more'.
【学生活动】Ss: Students listen to the song and fill in the comparative forms of the adjectives, noticing the pattern of adding '-er' to describe something becoming more.
Listen and fill in the blanks:
Grass gets greener（更绿）
Days gets warmer（更温暖）
Sun gets brighter（更亮）
Brighter and brighter
Dreams get bigger（更大）
Smiles get wider（更广阔）
Love gets stronger（更强大）
Stronger and stronger
It gets better（更好）
图3-3 Lead in 听歌填空（比较级感知）
【教师活动】T: Great! You found that 'greener', 'warmer', 'brighter' all end with '-er'. These are comparatives. We use comparatives to compare two things. For example, 'Grass gets greener' means the grass becomes more green.
【学生活动】Ss: Students repeat the lyrics and notice the comparative endings, understanding that '-er' and 'more' are used to show comparison.
【知识点】比较级感知：通过歌曲填空感知比较级的构成（-er/more），初步理解比较级用于比较两个事物的用法
【过渡语】我们已经感知了比较级，现在让我们学习1a中的反义词并掌握核心词汇。
Step 3 1a 反义词匹配与核心词汇学习（8~10 min）
1a Match each word with its opposite.
【教师活动】T: Open your books to 1a. Here are two groups of words. Match each word in the first group with its opposite in the second group. The first group: fast, shy, late, tall, lazy, loud, funny. The second group: outgoing, boring, short, quiet, early, slow, hard-working.
【学生活动】Ss: Students read the word lists and match each word with its opposite, then share their answers with the class.
1a 反义词匹配答案：
fast slow
shy outgoing
late early
tall short
lazy hard-working
loud quiet
funny boring
图3-4 1a 反义词匹配练习
【教师活动】T: Well done! Now let's learn the key words from this lesson. Look at these words: shy, lazy, loud, outgoing, hard-working, perform, alone, solve, flute. Some of them are from 1a, and some are from the listening conversation.
【学生活动】Ss: Students read the key words after the teacher, paying attention to pronunciation and meaning.
核心词汇讲解
单词 音标 词性 释义
shy / a / adj. 害羞的
lazy / le zi/ adj. 懒惰的；懒洋洋的
loud /la d/ adv. 响亮地 adj. 大声的
outgoing / a t ɡ / adj. 外向的
hard-working / hɑ d w k / adj. 勤奋的
perform /p f m/ v. 表演；执行
alone / l n/ adv. & adj. 独自；单独
solve /s lv/ v. 解决；解答
flute /flu t/ n. 长笛
【易错提示】loud 的词性
loud 既是副词（响亮地）也是形容词（大声的）。
例：She sings louder than Ella.（副词比较级，唱得更大声）
例：Don't be as loud as your brother.（形容词，大声的）
注意：比较级在词尾加-er或前面加more，不要同时使用。
【知识点】1a词汇学习：掌握7组反义词配对及9个核心词汇（shy/lazy/loud/outgoing/hard-working/perform/alone/solve/flute）
【过渡语】掌握了核心词汇后，让我们学习形容词比较级的构成规则。
Step 4 比较级构成规则（8~10 min）
Try to write the comparatives of the following words.
【教师活动】T: Now let's practice. Look at the words from 1a. Try to write the comparatives of these words. Think about the rules — when do we add '-er' and when do we use 'more'
【学生活动】Ss: Students write the comparatives of the 14 words, discussing the rules in pairs and noticing the different patterns.
原级 比较级
fast faster
shy shyer
late later
tall taller
lazy lazier
loud louder
funny funnier
slow slower
outgoing more outgoing
early earlier
short shorter
hard-working more hard-working
quiet quieter
boring more boring
图3-5 比较级构成练习
【教师活动】T: Let's summarize the rules. Who can tell me the rules for forming comparatives
【学生活动】Ss: Students summarize the rules based on the examples: single-syllable words add '-er', words ending in 'e' add '-r', consonant+y changes 'y' to 'i' and adds '-er', multi-syllable words use 'more'.
比较级构成规则小结：
1. 一般直接加-er：tall → taller, strong → stronger
2. 以e结尾加-r：nice → nicer, fine → finer
3. 辅音+y结尾变y为i加-er：happy → happier
4. 多音节词：前加more：beautiful → more beautiful
5. 不规则变化：good → better
图3-6 比较级构成规则小结
【理解要点】比较级构成规则
1. 一般直接加-er：tall → taller, strong → stronger
2. 以e结尾加-r：nice → nicer, fine → finer
3. 辅音+y结尾变y为i加-er：happy → happier, lazy → lazier
4. 多音节词前加more：beautiful → more beautiful, outgoing → more outgoing
5. 不规则变化：good → better
【知识点】比较级构成：掌握5条比较级构成规则（-er/-r/变y加-er/more/不规则），能正确写出常见形容词的比较级
【过渡语】掌握了比较级的构成规则，现在让我们进入听力练习。
Step 5 1b & 1c 听力训练（10~12 min）
1b Listen to the conversation at the music club and complete the sentences.
【教师活动】T: Now listen to two conversations. Conversation 1 takes place at the music club, and Conversation 2 takes place at the music festival. Listen and tick the correct place for each conversation.
【学生活动】Ss: Students listen to the two conversations and tick where each conversation takes place, focusing on key context clues.
1b 听力答案：
Conversation 1: at the music club（Peter和Chen Jie在音乐社团讨论音乐节）
Conversation 2: at the music festival（Mrs Brown在音乐节上观看Peter和Chen Jie的表演）
图3-7 1b 听力勾选练习
【重难点突破】人物比较信息提取
Step 1 听前预测：阅读1b题目，预测可能听到的人物特征
Step 2 首次听力：整体理解对话大意，完成1b勾选
Step 3 二次听力：逐题核对1c/1d，注意比较级形式
Step 4 核对答案：对照听力原文，纠正错误
1c Listen to the conversations again and complete the sentences.
【教师活动】T: Now listen again. This time, complete the sentences. Read the sentences first and try to predict the answers. Pay attention to the key information — who, what, and how they solve the problem.
【学生活动】Ss: Students read the sentences, predict the answers, then listen and fill in the blanks, checking their predictions against the listening.
1c 听力填空：
1. Peter and Chen Jie are talking about the _____________. Chen Jie is afraid of performing alone so they solve the problem by playing a song _________.
2. Mrs Brown and Peter are talking about _____ and _______ show.
答案：

空2: together（Chen Jie害怕独自表演，两人决定一起合奏）
空3: Ella（Mrs Brown和Peter谈论Ella和Emma的表演）
空4: Emma's（Ella和Emma的表演）
图3-8 1c 听力填空练习
【判断技巧】听力信息提取三步法
Step 1 听前预测：阅读题目，预测可能听到的人物和事件
Step 2 听中抓取：重点关注人物特征词（taller/louder/longer/better）和比较级结构
Step 3 听后核对：对照听力原文确认答案，注意比较级形式和主语对应关系
【知识点】1b/1c听力训练：通过预测-听取-核对的策略完成听力勾选和填空，训练抓住关键比较信息的能力
【过渡语】完成了听力练习，让我们听第三遍完成1d人物特征匹配，并学习对话原文。
Step 6 1d 听力匹配与对话原文学习（12~15 min）
1d Listen to the two conversations again. Match the characters with the correct descriptions.
【教师活动】T: Now listen to the conversations one more time. Match each character — Chen Jie, Peter, Emma, and Ella — with the correct descriptions. There are 8 descriptions in total. Pay attention to who is being compared.
【学生活动】Ss: Students listen carefully and match each character with the correct descriptions, noting the comparative forms used in the conversations.
1d 人物特征匹配答案：
Chen Jie:
● plays the Chinese flute better
● is shyer
● works harder
Peter:
● is more outgoing
Emma:
● is taller
● sings louder
Ella:
● has longer hair
● dances better
图3-9 1d 人物特征匹配练习
Conversation 1 原文学习
【教师活动】T: Let's read Conversation 1 together. Pay attention to the comparative sentences and the as...as... structure. 'You play the Chinese flute better than anyone else' — what does this mean
【学生活动】Ss: Students read Conversation 1 aloud, paying attention to intonation and the comparative structures.
Peter: Chen Jie, did you hear about the school music festival
Chen Jie: Yeah, it sounds fun.
Peter: Why don't you perform You play the Chinese flute better than anyone else in our music club.
Chen Jie: Well, I'm afraid of performing alone. I'm not as outgoing as you.
Peter: But you work harder than me. And last week you played a really beautiful song!
Chen Jie: You liked it Maybe we could play it together!
Peter: Great idea!
图3-10 对话1原文填空与知识点
【重点强调】as...as... 句型
as + 形容词/副词原级 + as ... = 和……一样……
例：I'm not as outgoing as you.（我不如你外向。）
否定形式：not as/so + 形容词/副词原级 + as ... = 不如……
注意：as...as...中间必须用原级，不能用比较级。
Conversation 2 原文学习
【教师活动】T: Now let's read Conversation 2. Mrs Brown is watching the performance at the music festival. Pay attention to how Peter and Chen Jie compare Emma and Ella.
【学生活动】Ss: Students read Conversation 2 aloud, noting the comparative sentences about Emma and Ella.
Mrs Brown: I loved your performance! You two did a wonderful job!
Peter and Chen Jie: Thank you!
Peter: Look, it's time for Ella and Emma's show!
Mrs Brown: Is that Ella singing
Peter: No, that's Emma. Emma is taller than Ella. And she sings louder than Ella.
Chen Jie: Look! That is Ella dancing. Her hair is longer than Emma's.
Peter: They both dance well, but I think Ella dances better than her sister.
图3-11 对话2原文填空
【易错提示】比较级中的 than
形容词比较级句子中通常含有标志词than，意思是'比'。
例：Emma is taller than Ella.（Emma比Ella高。）
例：You work harder than me.（你比我更努力。）
注意：比较级后必须有than（除非语境中省略），不能说 Emma is taller Ella。
【知识点】对话原文学习：分析两段对话中的人物比较信息，掌握比较级句型（A is taller than B / A plays better than B）和as...as...结构
【过渡语】理解了对话内容后，让我们运用1d的信息进行口语比较练习。
Step 7 1e 口语比较练习（8~10 min）
1e Use the information from 1d to make comparisons.
【教师活动】T: Now work in pairs. Use the information from 1d to make comparisons about the four characters. Ask and answer questions like 'Is Ella taller than Emma ' and 'Who dances better, Ella or Emma '
【学生活动】Ss: Students work in pairs, using the 1d information to ask and answer comparison questions about Chen Jie, Peter, Emma, and Ella.
1e 参考对话：

【学生活动】Ss: Students compare themselves with their partners using comparatives, practicing the sentence patterns learned in this lesson.
【重点强调】比较级句型小结
A is + 比较级 + than + B（A比B更……）
Emma is taller than Ella.
A plays/sings/dances + 比较级 + than + B（A做某事比B更好）
Ella dances better than Emma.
A is not as + 原级 + as + B（A不如B……）
Chen Jie is not as outgoing as Peter.
【知识点】1e口语练习：运用1d信息展开比较对话，实现比较级句型的真实交际运用
