Students share vocabulary they know. 2、The teacher writes the unit title "Amazing Plants and Animals" on the blackboard and introduces today's topic: Vocabulary in Use. 3、The teacher asks students to look at 2a and guess what the activity is about. [Teaching purpose] Activate students' prior vocabulary knowledge about animals and prepare them for the vocabulary focus of this lesson. step2：vocabulary practice - 2a (8mins) 1、The teacher asks students to work in pairs to circle the odd one in each group and give reasons. 2、Students share their answers. The teacher guides them to understand the categorization logic (e.g., habit is not a physical feature like height/size/weight). 3、The teacher summarizes the word groups: physical features, emotions, verbs of appearance, food/drink items. [Teaching purpose] Develop students' ability to categorize words and think critically about word meanings and relationships. step3：word formation - 2b (10mins) 1、The teacher introduces noun-forming endings (-ance, -(t)ion, -ness, -ity) with examples on PPT. 2、Students complete 2b individually, adding the correct endings to form nouns. The teacher circulates to help. 3、Students check answers in pairs, then the teacher reviews the answers with the whole class. [Teaching purpose] Help students master common noun-forming suffixes and expand their vocabulary through word formation rules. step4：sentence and passage practice - 2c and 2d (12mins) 1、The teacher asks students to complete 2c by choosing the correct word forms to fill in the blanks. Students work individually first. 2、Students compare answers with partners. The teacher checks answers and explains key points (e.g., "disappointed" describes feelings). 3、The teacher reads the passage in 2d aloud and asks students to listen carefully. 4、Students complete 2d by filling in the passage with correct word forms. The teacher provides hints and checks answers. [Teaching purpose] Consolidate vocabulary through contextualized practice in sentences and passages, improving students' ability to use words correctly. step5：group discussion and sharing (8mins) 1、The teacher asks students to discuss in groups: Why are frogs important? What can we learn from the passage in 2d? 2、Each group selects a representative to share their discussion results with the class. 3、The teacher summarizes the key messages and praises students' participation. [Teaching purpose] Provide opportunities for students to use the vocabulary they have learned to express their ideas and develop speaking skills. step6：homework (2mins) 1、Complete the vocabulary exercises (2a-2d) in the exercise book. 2、Make a word family chart using the suffixes learned today (-ance, -(t)ion, -ness, -ity) with at least 5 new words. 五、Blackboard Design 1、Unit 4 Amazing Plants and Animals - Vocabulary in Use. Key vocabulary: habit, height, size, weight, joy, happiness, appear, disappoint, imagine, store, weigh. Word endings: -ance, -(t)ion, -ness, -ity. Key passage: frogs and their importance in the ecosystem. 六、教学反思 1、本节课通过词汇分类和词缀构词法帮助学生系统梳理词汇，学生参与度较高，2a的找不同活动有效激发了思考。 2、部分学生对词缀辨析仍不够熟练，后续可增加更多例句巩固。 3、2d短文填空环节时间略紧，下次可提前布置预习让学生熟悉词汇。 学科网（北京）股份有限公司 $
