Unit 1 Charms of Nature Expressing Your Ideas 教案 -2025-2026学年高中英语人教版选修第一册

UNIT 1 Charms of Nature-Expressing Your Ideas 内容导航 This section, “Expressing Your Ideas” in Unit 1 “Charms of Nature”, is based on the theme of natural beauty and human-nature relationship. It guides students to integrate the vocabulary, sentence patterns and reading skills learned in the unit, express their feelings and views on natural scenery, environmental protection and human-nature harmony in oral and written forms, and focuses on cultivating students' ability to express their ideas clearly, logically and appropriately in English. It connects the input of reading materials with the output of language expression, helping students internalize knowledge and improve their comprehensive language application ability. 教学目标和重难点 1. 教学目标 Language Ability: Master the vocabulary and sentence patterns for describing natural scenery and expressing views, and improve the ability of oral and written expression. Cultural Awareness: Understand the different perceptions of natural beauty in various cultures, establish the concept of respecting and protecting nature, and enhance cultural confidence and cross-cultural communication awareness. Thinking Quality: Develop logical thinking through organizing and expressing views, and cultivate critical thinking by discussing the relationship between humans and nature. Learning Ability: Master effective learning strategies such as cooperative discussion and independent expression, and form the awareness of active practice and continuous improvement in language learning. 2. 教学重难点 Key Points: Master the core vocabulary (e.g., magnificent, serene, breathtaking, conservation) and sentence patterns for expressing feelings and views on nature; be able to clearly and fluently express personal perceptions of natural charms in oral and written forms. Difficult Points: How to use appropriate vocabulary and sentence structures to convey true feelings and unique views; how to organize ideas logically and coherently in oral reports and short essays; how to combine the theme of nature with practical life and put forward reasonable suggestions on environmental protection. 教学过程 Stage 1: Lead-in (Warm-up and Activation) Activity 1: Video Appreciation and Free Talk Show students a 3-minute English video about natural scenery, which includes magnificent mountains, clear lakes, lush forests, blooming flowers and other scenes, with simple English narration introducing the characteristics of each scenery. After watching the video, ask students to answer the following questions in English: “What natural scenery did you see in the video? Which part impressed you the most? Why?” Encourage students to speak freely, and guide them to use simple words and sentences to express their feelings, such as “I saw a beautiful lake. The water is very clear, and I feel relaxed when I look at it.” Design Intention: The video can intuitively show the charms of nature, arouse students' interest in the theme, and activate their existing vocabulary and expression experience related to natural scenery. Free talk provides a relaxed language environment for students, reduces their anxiety in speaking English, and lays a foundation for the subsequent expression activities. At the same time, it can detect students' current language level and adjust the teaching progress and content accordingly. Activity 2: Vocabulary and Sentence Pattern Review Display the core vocabulary and sentence patterns learned in the unit on the blackboard or courseware, including adjectives for describing natural scenery (magnificent, serene, breathtaking, rugged, picturesque), verbs for expressing feelings (admire, appreciate, cherish, adore), and sentence patterns such as “I am deeply impressed by...”, “The most fascinating part of nature is...”, “We should protect nature because...”. Ask students to read the vocabulary and sentence patterns aloud together, then invite several students to make sentences with the given vocabulary and sentence patterns. For example, ask a student to use “breathtaking” to make a sentence, and guide them to say “The sunset on the beach is breathtaking.” Design Intention: Reviewing the learned vocabulary and sentence patterns can help students consolidate the knowledge they have mastered, laying a solid foundation for their subsequent expression activities. Reading aloud together can enhance students' sense of language, and sentence-making practice can help students flexibly use the learned knowledge, improving their ability to apply language in context. This link also connects the previous learning content with the current “Expressing Your Ideas” module, ensuring the continuity and coherence of the teaching process. Stage 2: Presentation (Guide and Demonstration) Activity 1: Sample Analysis Present two English samples to students. Sample 1 is an oral report about “My Favorite Natural Scenery”, which introduces the speaker's favorite mountain scenery, including its characteristics, the feelings it brings, and the reasons why he likes it. Sample 2 is a short essay about “The Importance of Protecting Nature”, which expounds the charms of nature, the current problems of environmental damage, and puts forward some practical suggestions. Ask students to read the samples carefully, and then discuss the following questions in groups: “What is the main idea of each sample? What vocabulary and sentence patterns are used in the samples to express ideas? How are the ideas organized in the samples?” After the group discussion, invite representatives of each group to share their views. The teacher summarizes and comments, emphasizing the key points of expressing ideas: first, clarify the central idea, second, use appropriate vocabulary and sentence patterns to enrich the expression, third, organize the ideas logically (e.g., from description to feeling, from phenomenon to suggestion), and fourth, convey true feelings. At the same time, point out the advantages of the samples, such as the accurate use of vocabulary, the smooth connection of sentences, and the clear expression of views, and guide students to learn from these advantages. Design Intention: Sample analysis can provide students with specific examples of expression, let them have a clear understanding of how to express their ideas in English, and avoid the confusion of “not knowing how to start”. Group discussion can stimulate students' thinking, let them learn from each other, and deepen their understanding of the methods of expressing ideas. The teacher's summary and comments can help students sort out the key points of expression, correct possible misunderstandings, and guide students to form correct expression habits. Activity 2: Skill Guidance Based on the sample analysis, the teacher conducts targeted skill guidance, focusing on three aspects: vocabulary selection, sentence structure optimization, and idea organization. In terms of vocabulary selection, guide students to choose accurate and vivid vocabulary according to the content to be expressed. For example, when describing a quiet lake, they can use “serene” instead of “quiet”; when describing a grand mountain, they can use “magnificent” instead of “big”. At the same time, remind students to avoid repeating the same vocabulary, and use synonyms or antonyms to enrich the expression. For example, instead of always using “beautiful”, they can use “gorgeous”, “stunning”, “fascinating” and other words. In terms of sentence structure optimization, guide students to use a variety of sentence structures to make the expression more vivid and varied. For example, they can use simple sentences to express clear meanings, compound sentences (such as compound sentences with and, but, so, because) to connect ideas, and complex sentences (such as attributive clauses, adverbial clauses) to enrich the content. For example, instead of saying “The lake is clear. We can see the fish in it.”, they can say “The lake is so clear that we can see the fish swimming in it.” or “The lake, which is clear and transparent, allows us to see the fish in it.” In terms of idea organization, guide students to sort out their ideas before expressing them. For oral expression, they can list simple outlines, such as “Introduction of natural scenery → Feelings brought by it → Reasons for liking it”; for written expression, they can divide the article into three parts: beginning (putting forward the theme), body (expounding the theme with specific content) and ending (summarizing or putting forward suggestions). At the same time, remind students to use transition words (such as first, next, besides, finally, however, therefore) to connect sentences and paragraphs, ensuring the coherence of the expression. Design Intention: Skill guidance is the key link of this module. It can help students master scientific and effective expression skills, improve the quality of their expression, and avoid the problem of “simple and rough expression”. Targeted guidance on vocabulary, sentence structure and idea organization can help students break through the difficulties in expression, make their expression more accurate, vivid and logical, and lay a foundation for the subsequent practice activities. Stage 3: Practice (Cooperative Practice and Independent Expression) Activity 1: Group Cooperative Practice - Oral Expression Divide students into groups of 4-5, and assign a task to each group: “Discuss your favorite natural scenery in the group, and each member should introduce their favorite natural scenery, including its characteristics, the feelings it brings, and the reasons why you like it. Then, each group selects a representative to make an oral report to the whole class, with a duration of 2-3 minutes per report.” During the group discussion, the teacher walks around the classroom, observes the performance of each group, and provides timely guidance. For students who have difficulty expressing, the teacher can prompt them with appropriate questions, such as “What does the scenery look like? What do you usually do when you are in this scenery? How do you feel when you see it?”; for students who use simple vocabulary and sentence patterns, the teacher can guide them to use more vivid vocabulary and complex sentence structures. After the group discussion, each group's representative makes an oral report in turn. After each report, the teacher and other students make comments, pointing out the advantages and areas for improvement of the report, such as “Your report is very clear, but you can use more vivid vocabulary to describe the scenery.” or “Your idea is very good, but the connection between sentences can be smoother.” Design Intention: Group cooperative practice can create a positive interactive atmosphere for students, let them practice oral expression in cooperation and communication, and improve their speaking ability. The teacher's on-site guidance can help students solve problems in time, avoid wrong expression habits, and improve the efficiency of practice. Comments from teachers and students can help students recognize their own advantages and shortcomings, learn from each other, and continuously improve their oral expression ability. At the same time, cooperative practice can also cultivate students' cooperative spirit and communication ability. Activity 2: Independent Practice - Written Expression Ask students to complete a short essay independently, with the theme of “My View on the Relationship Between Humans and Nature”. The requirements are as follows: 1. Clarify the central idea, which can be about the importance of protecting nature, the harm of environmental damage, or the ways to achieve harmony between humans and nature; 2. Use the vocabulary and sentence patterns learned in the unit, and try to use a variety of sentence structures; 3. Organize the ideas logically, with clear beginning, body and ending; 4. Convey true feelings and put forward reasonable views or suggestions. Before writing, the teacher reminds students to sort out their ideas first, list a simple outline, and then start writing. During the writing process, the teacher walks around the classroom, provides guidance for students who have difficulty writing, such as helping them sort out their ideas, prompting them with appropriate vocabulary and sentence patterns, and correcting their grammatical mistakes in time. After students finish writing, ask them to check their own articles first, focusing on checking whether the vocabulary is accurate, whether the sentence structure is correct, whether the ideas are coherent, and whether there are spelling and grammatical mistakes. Then, let students exchange their articles with their deskmates, and help each other check and revise, putting forward revision suggestions. Design Intention: Independent practice can test students' ability to apply the learned expression skills independently, and help students internalize the knowledge and skills they have mastered. Asking students to list an outline before writing can help them organize their ideas logically and avoid the problem of “disorganized writing”. The teacher's on-site guidance can help students solve difficulties in writing in time, and peer review can let students learn from each other, find their own shortcomings, and improve their writing ability. At the same time, independent practice can also cultivate students' independent thinking ability and sense of responsibility. Activity 3: Comprehensive Practice - Speech Competition Organize a small speech competition with the theme of “Charm of Nature, Our Responsibility”. Ask students to prepare a speech based on their written essays, with a duration of 3-4 minutes per speech. Invite several students as judges, and the teacher formulates the evaluation criteria: 1. Clear central idea and logical organization; 2. Accurate and vivid vocabulary, flexible use of sentence patterns; 3. Fluent speaking, standard pronunciation and intonation; 4. True feelings and strong appeal. During the speech competition, each student takes turns to give a speech, and the judges score according to the evaluation criteria. After all speeches are completed, the teacher summarizes the competition, commends the outstanding students, and comments on the overall performance of the students, pointing out the common advantages and problems, and putting forward suggestions for improvement. Design Intention: The speech competition integrates oral expression and written expression, which can comprehensively test students' language expression ability and comprehensive quality. It can arouse students' enthusiasm and initiative in participation, let them show their expression ability in a competitive atmosphere, and enhance their confidence in speaking English. The evaluation of judges and teachers can help students have a more comprehensive understanding of their own expression level, and the commendation of outstanding students can stimulate students' learning motivation. At the same time, the theme of the speech is closely related to the unit theme, which can further deepen students' understanding of the relationship between humans and nature and enhance their sense of environmental protection. Stage 4: Consolidation and Extension Activity 1: Summary and Reflection The teacher leads students to summarize the key points of this lesson: the methods and skills of expressing ideas about nature in English, including vocabulary selection, sentence structure optimization and idea organization; the requirements of oral and written expression. Then, ask students to reflect on their own performance in this lesson, such as “What have I learned in this lesson? What are my advantages in expressing ideas? What aspects do I need to improve? What difficulties have I encountered and how to solve them?” Encourage students to speak freely and share their reflections, and the teacher gives appropriate guidance and encouragement. Design Intention: Summary can help students sort out the knowledge and skills learned in this lesson, form a systematic cognitive structure, and deepen their memory and understanding. Reflection can help students recognize their own advantages and shortcomings, clarify the direction of improvement, and cultivate their ability of self-reflection and self-improvement. The teacher's guidance and encouragement can enhance students' confidence in learning and stimulate their enthusiasm for continuous learning. Activity 2: Extension Task Assign an extension task to students: 1. Observe the natural scenery around you (such as parks, rivers, mountains near your home or school), take a photo, and write a short English introduction (about 80-100 words) to describe the scenery in the photo, including its characteristics and your feelings; 2. Collect English articles or speeches about natural protection, read them carefully, and extract the key points and useful vocabulary and sentence patterns, and share them in the next class. At the same time, remind students to use the expression skills learned in this lesson to complete the task, and pay attention to the accuracy and fluency of the expression. Design Intention: The extension task connects the classroom learning with real life, making the language learning more practical and interesting. Observing the natural scenery around can let students feel the charm of nature personally, stimulate their love for nature, and at the same time provide real materials for their expression. Collecting English articles or speeches about natural protection can expand students' horizons, enrich their vocabulary and expression experience, and further enhance their sense of environmental protection. This task also can consolidate the knowledge and skills learned in this lesson, and promote the continuous improvement of students' language expression ability. Stage 5: Evaluation and Feedback Activity 1: Multi-dimensional Evaluation Carry out multi-dimensional evaluation of students' performance in this lesson, including teacher evaluation, peer evaluation and self-evaluation. Teacher evaluation focuses on students' participation in classroom activities, the mastery of expression skills, and the quality of oral and written expression, and gives specific and targeted comments and suggestions. Peer evaluation focuses on the performance of students in group discussions, oral reports and speech competitions, and puts forward objective evaluation and revision suggestions. Self-evaluation requires students to evaluate their own learning process and results according to the learning objectives and evaluation criteria, and put forward plans for improvement. The teacher collects students' written essays, extension tasks and self-evaluation forms, sorts out and analyzes them, summarizes the common problems of students, such as inaccurate use of vocabulary, incorrect sentence structure, disorganized ideas, etc., and prepares targeted review and guidance for the next class. At the same time, the teacher records the outstanding performance of students, and gives timely praise and encouragement. Design Intention: Multi-dimensional evaluation can comprehensively and objectively reflect students' learning results and performance, avoid the one-sidedness of single teacher evaluation. Teacher evaluation can help students understand their own learning level and direction of improvement; peer evaluation can promote students' mutual learning and communication; self-evaluation can cultivate students' self-management ability and sense of responsibility. The analysis of students' works and self-evaluation forms can help teachers grasp students' learning situation in time, adjust teaching strategies, and improve teaching effect. Activity 2: Feedback and Guidance The teacher feeds back the evaluation results to students in the next class, focusing on the common problems and outstanding cases. For common problems, the teacher conducts targeted guidance and explanation, such as explaining the correct use of certain vocabulary and sentence patterns, demonstrating how to organize ideas logically, and letting students practice again. For outstanding cases, the teacher shares them with the whole class, lets students learn from them, and encourages other students to learn from them. At the same time, the teacher answers the questions raised by students in the learning process, and provides personalized guidance for students with special difficulties. Design Intention: Feedback and guidance are important links to improve teaching effect. Timely feedback can let students know their own learning results and problems, and clarify the direction of improvement. Targeted guidance can help students solve common problems, consolidate the knowledge and skills they have learned, and avoid the accumulation of mistakes. Sharing outstanding cases can stimulate students' learning motivation, and personalized guidance can meet the different learning needs of students, ensuring that every student can make progress in this module. Conclusion: This teaching process takes “Expressing Your Ideas” as the core, closely around the theme of “Charms of Nature”, and integrates lead-in, presentation, practice, consolidation and evaluation. It focuses on cultivating students' four-dimensional core literacy, pays attention to the combination of knowledge input and language output, and the connection between classroom learning and real life. Through a variety of teaching activities, students are guided to master the skills of expressing ideas in English, improve their comprehensive language application ability, and at the same time establish the concept of protecting nature and enhance their sense of social responsibility. Each link of the teaching process is designed with clear intentions, which not only pays attention to the improvement of students' language ability, but also focuses on the cultivation of their thinking quality, cultural awareness and learning ability, so as to achieve the teaching goal of this module. 1 / 1 学科网（北京）股份有限公司 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $
