Difficult Points: Understand the implied meaning of the text and the metaphorical expressions, and use the learned knowledge to express personal views on "no limits". 教学过程 Step 1: Lead-in (Warm-up and Lead-in) The teacher starts the class with a question-and-answer interaction: “Have you ever faced a challenge that made you feel helpless? How did you deal with it? Do you think there are any limits in our life?” Then, the teacher shows some short video clips or pictures, including Paralympic athletes overcoming physical disabilities to win honors, scientists breaking through research bottlenecks, and teenagers challenging themselves in extreme sports. After watching, invite 2-3 students to share their feelings in English briefly. Then, the teacher naturally leads to the topic of the unit: “Today, we will read a passage about breaking limits and explore the true meaning of ‘No Limits’ together.” Design Intention: This lead-in links students’ real life with the theme of the unit, stimulates students’ learning interest and emotional resonance through vivid audio-visual materials. The question-and-answer interaction not only activates students’ existing knowledge and experience, but also creates a relaxed English communication atmosphere, laying a foundation for the subsequent reading and interaction links. At the same time, it implicitly guides students to think about the connotation of “breaking limits”, which is in line with the requirement of cultivating students’ thinking quality. Step 2: Pre-reading (Vocabulary and Background Preview) First, the teacher presents the core vocabulary and phrases of the reading passage, including blame, pressure, statistic, seatbelt, solution, independent, surf, adapt, reveal, limit, etc. For each word and phrase, the teacher explains its meaning in simple English, combines it with the context of the passage to give example sentences, and guides students to read aloud to master the correct pronunciation and usage. For example, when explaining “blame”, the teacher says: “Blame means to say that someone or something is responsible for a bad situation. In the passage, it mentions ‘Blame your brain’, which means your brain is the reason for some behaviors.” Then, the teacher briefly introduces the background of the passage: The passage is a narrative and expository text that explores why teenagers tend to take more risks, analyzes the reasons from the perspectives of brain development, peer pressure and other aspects, and puts forward suggestions on how to make wise choices. It combines scientific knowledge with real life, which is close to students’ actual situation. After the vocabulary and background preview, the teacher asks students to predict the content of the passage based on the title “No Limits” and the previewed information: “What do you think the passage will talk about? Will it tell a story or explain a scientific phenomenon? What kinds of ‘limits’ will be mentioned?” Students can discuss in pairs for a short time and then share their predictions. Design Intention: Vocabulary is the foundation of reading comprehension. Previewing core vocabulary helps students reduce reading obstacles and improve reading efficiency. Explaining vocabulary in English and combining it with the context of the passage helps students master the practical usage of words, which is conducive to cultivating their language ability. Background introduction enables students to have a preliminary understanding of the style and content of the passage, laying a foundation for in-depth reading. Predicting the passage content can stimulate students’ reading motivation, cultivate their ability of logical reasoning and prediction, and exercise their thinking quality. Step 3: While-reading (In-depth Reading and Information Extraction) This step is divided into three parts: skimming, scanning and careful reading, to guide students to extract information layer by layer and understand the passage in depth. Skimming: Ask students to read the passage quickly, ignore the new words they don’t understand temporarily, and focus on the main idea of the passage. After reading, ask students to answer the following questions: “What is the main topic of the passage? What is the author’s purpose in writing this passage?” Then, invite several students to share their answers, and the teacher summarizes and corrects them: The main topic of the passage is why teenagers take more risks and how to make wise choices; the author’s purpose is to help teenagers understand the reasons for their risky behaviors and guide them to break the wrong limits and make rational choices. Design Intention: Skimming training helps students master the reading strategy of grasping the main idea quickly, which is an important part of improving students’ reading ability. Through answering questions, it can test students’ understanding of the main idea, and guide students to form a holistic understanding of the passage, laying a foundation for in-depth reading. Scanning: Ask students to read the passage again, scan for specific information, and complete the following information form. The form includes four columns: Reasons for Teenagers’ Risk-taking Behaviors, Specific Performances, Scientific Explanations, and Suggestions. Students need to find relevant information from the passage and fill in the form accurately. During the process, the teacher walks around the classroom, provides guidance for students who have difficulties, and reminds students to pay attention to key sentences and signal words (such as first, besides, finally, etc.). After students finish filling in the form, invite a group to present their answers, and the teacher checks and supplements them, emphasizing the key information and difficult sentences in the passage. Design Intention: Scanning training helps students master the strategy of extracting specific information quickly, which is conducive to improving their reading efficiency and accuracy. The information form can help students sort out the structure of the passage and clarify the logical relationship between different parts of the passage, which is conducive to cultivating their logical thinking ability. The teacher’s guidance can help students solve difficulties in time, ensure that all students can participate in the reading activity, and reflect the teaching concept of student-oriented. Careful Reading: Guide students to read the passage carefully, focus on understanding the implied meaning of the text, difficult sentences and rhetorical devices, and deepen their understanding of the theme. First, the teacher lists several difficult sentences in the passage, such as “The real barrier was not his wheelchair but people’s stares”, “The last part to fully develop is the frontal cortex, which allows us to control feelings and make good decisions”, and explains them in detail. For example, when explaining the first sentence, the teacher guides students to analyze the metaphorical meaning: “Wheelchair is a physical tool, but people’s stares represent social prejudice. The sentence implies that the biggest limit for disabled people is not their physical disability, but the prejudice from society.” Then, the teacher asks students to find other metaphorical expressions or key sentences in the passage, discuss in groups, and analyze their meanings. In addition, guide students to think about the following questions: “What is the author’s attitude towards teenagers’ risk-taking behaviors? Do you agree with the author’s suggestions? Why?” Design Intention: Careful reading is the key link to understand the passage in depth. Explaining difficult sentences helps students break through reading obstacles and improve their ability to understand complex sentences. Analyzing metaphorical expressions and key sentences helps students grasp the deep connotation of the text, cultivate their ability of text analysis and logical reasoning, and improve their thinking quality. Group discussion encourages students to communicate and cooperate, express their views, and improve their interactive expression ability and cooperative learning ability. Step 4: Post-reading (Consolidation and Interaction) This step includes three activities: vocabulary consolidation, group discussion and interactive expression, to help students consolidate the learned knowledge, apply it flexibly, and deepen their understanding of the theme. Vocabulary Consolidation: The teacher designs a fill-in-the-blank exercise. The exercise uses the core vocabulary and phrases of the passage, and the context is closely related to the content of the passage. For example: “Many teenagers take more risks because of the low level of dopamine in their brains. They need to take risks to get the wow factor. When facing peer pressure, they should be independent and make wise choices instead of being pushed into doing dangerous things.” Students complete the exercise independently, and then the teacher checks the answers and explains the key points again, helping students consolidate the usage of vocabulary and phrases. Design Intention: Vocabulary consolidation exercise helps students consolidate the core vocabulary and phrases learned in the passage, and improve their ability to use vocabulary in context. The context of the exercise is closely related to the passage, which can help students connect the vocabulary with the theme of the unit, and lay a foundation for subsequent language application. Group Discussion: Divide students into groups of 4-5, and assign the discussion topic: “Combined with the passage and your own life experience, discuss: What are the limits you have faced in your study and life? How can you break these limits? What can we learn from the spirit of ‘No Limits’?” Before the discussion, the teacher gives some guiding questions to help students sort out their ideas: “What is your biggest limit now? Is it a physical limit, a psychological limit or a social limit? What methods have you tried to break it? What difficulties have you encountered? How can we apply the suggestions in the passage to break our own limits?” During the discussion, the teacher walks around the classroom, listens to the discussion of each group, provides guidance for students who have difficulties in expression, and encourages students to express their views bravely in English. After the discussion, each group sends a representative to share the group’s views, and the teacher makes comments and summaries, affirming the positive views of the students and guiding them to establish a correct view of “breaking limits”. Design Intention: Group discussion is an important link to realize interactive teaching. It can not only improve students’ oral expression ability and cooperative learning ability, but also guide students to combine the text content with their own life experience, deepen their understanding of the theme of “No Limits”, and cultivate their ability of critical thinking and practical application. The teacher’s guidance and comments can help students standardize their oral expression, correct their wrong views, and ensure the effectiveness of the discussion. Interactive Expression: The teacher designs a role-play activity. Assign different roles to students: a teenager who likes to take risks, a parent who is worried about the teenager, a scientist who explains the reasons for teenagers’ risk-taking behaviors, and a teacher who gives guidance. Students need to design dialogues according to their roles, combining the knowledge and views learned in the passage. For example, the teenager can talk about his own risk-taking experiences and feelings, the parent can express his worries, the scientist can explain the relationship between brain development and risk-taking behaviors, and the teacher can put forward reasonable suggestions. After the role-play, invite several groups to perform in front of the class, and the teacher makes comments, focusing on evaluating students’ oral expression, the rationality of the dialogue and the application of the learned knowledge. Design Intention: Role-play activity makes the language learning more vivid and interesting, which can stimulate students’ enthusiasm for participation and improve their oral expression ability and language application ability. Through role-play, students can better understand the different perspectives on teenagers’ risk-taking behaviors, deepen their understanding of the passage content, and cultivate their ability of empathy and communication, which is in line with the requirements of cultivating students’ language ability and social communication ability. Step 5: Summary and Extension First, the teacher leads students to summarize the content of the lesson: Review the main idea of the passage, the core vocabulary and phrases, the reasons for teenagers’ risk-taking behaviors and the corresponding suggestions, and emphasize the theme of “No Limits” — the real limit is not the objective difficulty, but the subjective cognition. We should bravely break the wrong limits, make rational choices, and pursue our dreams with perseverance. Then, the teacher designs the extension activity: Ask students to write a short passage (80-100 words) after class, with the title “My Way to Break Limits”, which combines their own life experience and the knowledge learned in the lesson, describing the limits they have faced and the process of breaking them. At the same time, recommend relevant English materials for students to read after class, such as English articles about famous people breaking limits, TED speeches on the theme of “No Limits”, etc., to expand their horizons and accumulate language materials. Design Intention: Summarizing the lesson helps students sort out the knowledge learned in the class, form a systematic knowledge structure, and deepen their understanding of the theme. The extension activity combines classroom learning with after-class practice, which can not only consolidate the learned knowledge, but also improve students’ writing ability and autonomous learning ability. Recommending relevant materials helps students expand their learning channels, accumulate language materials, and cultivate their interest in English learning, which is in line with the requirement of cultivating students’ learning ability. 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 $
