教学过程

教学环节	教师活动	学生活动	设计意图
Step 1: Warming-up & Lead-in (热身与导入) (约5分钟)	Greetings: Greet the students and ask them about their mood. 2. Song & Game: Play a short, lively song or show a funny video clip to get students relaxed. Then, ask: "Is the song happy or sad?" "Is the video funny or serious?" 3. Lead-in: Show two contrasting pictures (e.g., a sunny beach vs. a quiet library). Ask: "Which place do you like? Why? Is it fun or boring?" Guide students to use simple adjectives to describe.	Greet the teacher and answer questions. 2. Enjoy the song/video and answer the teacher's questions using happy, sad, funny, serious. 3. Look at the pictures and try to describe them using the adjectives they know.	通过轻松的歌曲和图片，快速吸引学生注意力，复习旧知（简单形容词），自然地引出本课主题——比较事物，为新知识的学习做好铺垫。
Step 2: Presentation (新知呈现) (约15分钟)	Vocabulary Teaching: Present pictures of two people with different personalities (e.g., an outgoing person talking to many friends vs. a quiet person reading alone). Introduce the new words: outgoing, quiet. Use the same method to present funny, hard-working, serious with clear examples and pictures. Read the words aloud and have students repeat. 2. Sentence Pattern Presentation: Point to the two pictures of outgoing and quiet. Ask: "Who is more outgoing?" Guide students to answer: "The person on the left is more outgoing." Write the sentence structure on the blackboard: A + be + more + 形容词原级 + than + B. Give more examples: "Sam is more serious than Tom." "Tina is funnier than Tara." Introduce the comparative form for short adjectives: "tall" -> "taller", "short" -> "shorter". Explain the rule: add -er. * Explain the rule for long adjectives (with more than two syllables): "outgoing" -> "more outgoing", "beautiful" -> "more beautiful". 3. Drill: Show pictures of famous cartoon characters (e.g., Tom & Jerry, Shrek & Donkey). Ask students to make sentences using the pattern.	Look at the pictures, listen to the teacher, and learn the new words. Repeat the words after the teacher. 2. Listen to the teacher's questions and try to answer. 3. Observe the sentence structure on the blackboard and try to understand the rule. 4. Actively participate in the drill, making sentences about the cartoon characters.	直观的图片和情境帮助学生在语境中理解和记忆新词汇，通过对比，自然引出核心句型，归纳总结比较级的构成规则，有助于学生形成系统的语法认知，利用学生熟悉的卡通人物进行操练，增加了趣味性和参与度。
Step 3: Practice (巩固练习) (约10分钟)	Listening (1b): Ask students to look at the picture in 1a. Play the recording for 1b. Play it again and ask students to circle the words they hear. Check the answers with the class. 2. Pair Work (1c): Ask students to work in pairs. Let them practice the conversation in 1c, using the information from the picture in 1a. Encourage them to create their own conversations. Walk around the classroom to offer help and monitor their progress. * Invite a couple of pairs to present their dialogues to the class.	Look at the picture and listen to the recording carefully. Circle the words they hear. 2. Work with their partner, read the sample dialogue, and then create their own conversations using the target language. 3. Act out their dialogues in front of the class.	听力练习训练学生抓取关键信息的能力，结对活动为学生提供了在真实语境中运用目标语言的机会，从模仿到创造，逐步内化知识，展示环节则增强了学生的成就感和自信心。
Step 4: Production (拓展运用) (约10分钟)	Survey: Divide the class into small groups of 4-5. Give each group a task: Interview their group members and find out who is hard-working, funny, outgoing, etc. Provide a simple survey form on the PPT or on the blackboard: Name: __ Who is more hard-working than you? __ Who is funnier than you? __ Who is more outgoing than you? __ 2. Report: After the survey, ask a group leader to report their findings to the class. * Example: "In our group, Li Ming is more hard-working than me. Wang Hua is funnier than me."	Work in groups, ask and answer questions according to the survey task. 2. Take notes and prepare a short report. 3. The group leader stands up and reports their group's findings to the whole class.	这是一个从控制性练习到自由交际的过渡，调查活动将语言学习与学生自身生活紧密联系，极大地激发了学生的参与热情，这不仅巩固了所学知识，还锻炼了学生的信息整理、口头汇报和合作能力。
Step 5: Summary & Homework (总结与作业) (约5分钟)	Summary: Ask students: "What have we learned today?" Guide them to summarize the key vocabulary and sentence patterns. Review the rules of forming comparative adjectives. 2. Homework: Level 1 (基础): Copy the new words and sentences three times. Level 2 (巩固): Write five sentences to compare yourself with your best friend or a family member. Level 3 (拓展): Interview your parents and write a short paragraph comparing them when they were young and now. (e.g., "My father is more serious now than he was 20 years ago.")	Recall what they have learned and participate in the summary. 2. Listen carefully and write down the homework assignments.	总结环节帮助学生梳理本课知识，形成知识体系，分层作业设计体现了因材施教的原则，既保证了所有学生都能巩固基础，又为学有余力的学生提供了拓展空间，将课堂学习延伸到课外。

教学反思

本教案的设计力求体现以学生为主体的教学理念,通过多种互动形式激发学生的学习兴趣。

• 成功之处:

  1. 情境导入和卡通人物的使用有效调动了课堂气氛,学生参与度高。
  2. 从词汇到句型，再到自由对话和调查活动，层层递进,符合学生的认知规律。
  3. 分层作业设计照顾到了不同层次学生的需求,有助于个性化发展。

• 待改进之处:

  1. 在Pair Work环节，可能会出现部分学生语言组织能力不足，无法顺利开口的情况，下次可以准备一些句型卡片或关键词提示,帮助他们更好地完成任务。
  2. 对于形容词比较级的不规则变化，本课时只做了简单提及,下一课时需要重点强化和练习。
  3. 在小组活动中，要更好地关注“沉默的少数”,确保每个学生都有机会参与。
