三、教学过程
学习活动 效果评价
◆Step 1　Lead-in Show a video about nature.Ask the students to remember what they can see and hear. 观察学生对动植物等主题的兴趣专注度,感受大自然的神奇。
设计意图:通过观看视频,激活学生的已有知识,激发学习兴趣,同时为新课内容的引入创造自然过渡。
◆Step 2　Pre-listening Work on 1a Present the words in the box “beautiful,big,fast,heavy,large,long,old,small,tall,short” on the blackboard or PPT.Explain the meanings and pronunciations of these words,especially the superlative forms.Use some simple examples to help students understand how to use them,like “The elephant is big.The blue whale is the biggest animal in the world.” 通过让部分学生朗读,检查他们对单词发音的掌握情况。通过简单例子,观察他们是否能理解最高级的基本用法。
设计意图:为接下来的听说活动奠定词汇基础,帮助学生理解最高级在描述动植物语境中的用法。
◆Step 3　While-listening 1.Work on 1b Play the recording of the dialogues for students to listen for the first time.Ask them to number the plants and animals in 1a in the order they hear them. 2.Work on 1c Play the recording again.This time,ask students to match the words “heaviest,largest,most beautiful,oldest,fastest,tallest” with the plants and animals in 1a.Some may have two answers.Students complete the task individually.Then,have students discuss their answers in groups of four. 在1b和1c听力练习中,多数学生基本掌握,少数学生掌握起来有困难。学生整体掌握水平有差异,后续需针对性教学提升。
设计意图:训练学生在听力材料中捕捉主要信息的能力,使他们熟悉对话的整体内容。
◆Step 4　Post-listening 1.Write down some sentences according to the listening materials. (1)Moss is one of the oldest plants in the world. (2)The blue whale is the largest and heaviest animal in the world. (3)… 2.Pair work. A:What's amazing about the cheetah B:It runs the fastest. 3.Group work Divide students into groups of 4.Each group chooses one plant or animal they are interested in,and then discusses more amazing things about it, and writes them down.After 5 minutes,each group selects a representative to share their findings with the whole class. 观察学生的口语表现,包括发音、语调、语法以及所学知识的运用情况。提供个性化反馈,帮助他们改进。评估学生在小组讨论和展示中的表现,包括分享信息的内容、语言使用以及在公共场合发言的自信程度。
设计意图:让学生在真实情境中练习使用目标语言,提高口语表达能力和语言流利度。培养学生自主探索和拓展知识的能力,以及公共演讲和信息分享的技能。进一步增强他们对令人惊叹的动植物这一话题的兴趣。
◆Step 5　Pronunciation 1.Present the table in Pronunciation 1,teach the phonetic symbols and words,and ask students to pay attention to the pronunciation rules. 2.Play the recording,and let students follow and read.Then ask students to add one more word that follows the same pronunciation rule to each group on their own. 3.Play the recording of Pronunciation 2,ask students to notice the differences in sentence stress and meaning,and follow and imitate. 观察学生跟读的准确性、单词添加的合理性以及对句子重音的理解,评估学生是否能够掌握目标音标的发音规则,并判断听力活动是否有效提升了学生的语音意识和发音能力。
设计意图:通过系统的发音教学和听力练习,帮助学生掌握目标音标的发音规则,理解重音对句子意义的影响,从而提升学生的语音准确性和听力理解能力。

课堂评价
作业布置
必做: Create information cards for the animals and plants in 1a,label the corresponding adjectives (e.g.,blue whale—largest,heaviest),and attempt to describe other common animals and plants using superlatives (e.g.,panda—most lovely). 选做: Investigate a plant or animal of interest,describe its characteristics using superlatives (e.g.,“The sunflower is one of the tallest flowers in my garden.”),create an illustrated poster,and share it with the class.
教学反思
　　在教学过程中,Pre-listening 环节的头脑风暴和词汇引入成功激发了学生的兴趣,调动了他们已有的知识。然而,在词汇讲解时,部分学生对形容词最高级的构成和用法理解不够深入,后续应多加练习。While-listening 环节中,学生在第一次听力捕捉顺序信息时表现欠佳,需要加强专项训练。小组讨论时,存在部分小组参与度不均衡的情况,教师应更有效地进行引导。Post-listening 环节,学生在口语表达中仍存在一些语法和发音错误,这提示在今后教学中要持续进行纠正和强化训练。总体而言,学生对动植物话题兴趣浓厚,但听说能力的提升需要更多样化的练习和长期的培养。
