Unit 1 Beware and take care-Assessment 教案-2025-2026学年高中英语译林版选修第二册

Unit 1 Beware and take care-Assessment 教学目标和重难点 1. 教学目标 It focuses on language ability, cultural awareness, thinking quality and learning ability, enabling students to master safety-related vocabulary and expressions, understand safety cultures at home and abroad, develop logical thinking, and form autonomous and cooperative learning habits. 2. 教学重难点 Key points: Master core vocabulary (e.g., caution, hazard, prevent) and sentence patterns about safety warnings; understand safety-related passages. Difficult points: Use language flexibly to express safety warnings and solve practical safety problems. 教学过程 Lead-in: Safety Awareness Activation The teacher starts the class by showing a series of real-life safety-related pictures and short videos, including scenes like wet floors with warning signs, crowded public places, and potential fire hazards. Then the teacher asks students two questions: “What potential safety hazards can you find in these pictures?” and “What warnings should we give in such situations?” After students share their answers freely, the teacher writes down key words and expressions they mention on the blackboard, such as “be careful”, “watch out”, “wet floor”, “danger”, and then naturally leads to the unit theme “Beware and take care”. Finally, the teacher briefly introduces the learning objectives of this unit: to master safety-related vocabulary and sentence patterns, to understand safety tips in different situations, and to learn to express safety warnings in English. Design Intention: The real-life pictures and videos can quickly attract students’ attention and arouse their interest in learning. By asking questions, students can activate their existing knowledge and life experience about safety, laying a foundation for the subsequent learning of new knowledge. Meanwhile, introducing learning objectives helps students clarify their learning direction and enhance their learning initiative. Presentation: New Knowledge Input Vocabulary Teaching The teacher presents the core vocabulary of the unit one by one, combining pictures, definitions and example sentences to help students understand and remember. For example, when teaching the word “caution”, the teacher shows a picture of a caution sign, gives the definition “a warning or piece of advice about a possible danger, problem, or difficulty”, and makes an example sentence: “We need to exercise caution when crossing the road.” For the word “hazard”, the teacher explains it as “a thing that is dangerous and likely to cause harm”, and uses the example: “Smoking is a serious hazard to health.” For phrasal verbs like “watch out for” and “look out for”, the teacher demonstrates their usage through situational dialogues: “A: Watch out for the car! B: Thank you, I almost didn’t see it.” After presenting each word and phrase, the teacher invites students to make their own sentences, and corrects their mistakes in pronunciation and grammar in time. Then, the teacher organizes a quick memory game: show the Chinese meaning of the vocabulary, and ask students to respond with the corresponding English words or phrases as quickly as possible. This game can help students consolidate the newly learned vocabulary in a relaxed atmosphere. Design Intention: Combining pictures, definitions and example sentences can help students understand the meaning and usage of vocabulary more intuitively, avoiding mechanical memorization. Asking students to make sentences can test their mastery of vocabulary and improve their ability to use vocabulary flexibly. The quick memory game can stimulate students’ learning enthusiasm and strengthen their memory of vocabulary. Sentence Pattern Teaching Based on the vocabulary learned, the teacher presents the key sentence patterns of the unit, which are mainly used to express safety warnings. The key sentence patterns include: “Beware of + n./doing sth.”, “Be careful not to + do sth.”, “You’d better + do sth. to avoid danger”, “It’s dangerous to + do sth.”, etc. The teacher explains the structure and usage of each sentence pattern in detail with example sentences. For example, “Beware of the dog.” (Beware of + n.), “Beware of touching the hot wire.” (Beware of + doing sth.), “Be careful not to fall off the stairs.” (Be careful not to + do sth.), “You’d better wear a helmet to avoid danger.” (You’d better + do sth. to avoid danger), “It’s dangerous to swim in the deep river.” (It’s dangerous to + do sth.). Then, the teacher asks students to practice these sentence patterns in pairs, using the vocabulary they just learned. For example, students can make dialogues about safety in the school, at home or in public places. Design Intention: Sentence pattern teaching is closely combined with vocabulary teaching, which helps students form a complete language system. Pair practice can provide students with more opportunities to speak, improve their oral expression ability, and make them familiar with the usage of sentence patterns in practical communication. Text Reading The teacher distributes the reading material of the unit, which is a passage about common safety hazards in daily life and corresponding prevention measures. First, the teacher asks students to read the passage quickly and answer two questions: “What are the common safety hazards mentioned in the passage?” and “What prevention measures are given?” This helps students grasp the main idea of the passage. Then, the teacher asks students to read the passage carefully. During the reading process, students need to underline the new words and difficult sentences they don’t understand. After reading, the teacher leads students to analyze the passage paragraph by paragraph: explains the difficult words and sentences, sorts out the logical structure of the passage, and helps students understand the details of the passage. For example, the teacher explains the sentence “It’s crucial to keep a clear mind when facing unexpected dangers, as panic can often lead to more serious consequences.”, emphasizing the importance of keeping calm in danger and explaining the meaning of “crucial” and “panic”. After analyzing the passage, the teacher organizes a group discussion: “What other safety hazards do we have in our daily life that are not mentioned in the passage? What prevention measures can we take?” Each group discusses for a few minutes and then sends a representative to share their opinions. The teacher comments on students’ opinions and supplements relevant safety knowledge. Design Intention: Fast reading training can improve students’ reading speed and ability to grasp the main idea. Careful reading and detailed analysis can help students understand the passage thoroughly, master new vocabulary and sentence patterns in the context, and improve their reading comprehension ability. Group discussion can stimulate students’ thinking, cultivate their cooperative learning ability, and connect the knowledge learned with real life. Practice: Knowledge Consolidation and Application Vocabulary and Sentence Pattern Practice The teacher designs a fill-in-the-blank exercise. The exercise includes 10 blanks, which need to be filled with the newly learned vocabulary and sentence patterns. For example: 1. We should exercise ______ (caution) when using electrical appliances. 2. ______ (Beware of) the broken glass on the ground. 3. It’s dangerous ______ (swim) in the lake without adult supervision. After students finish the exercise independently, the teacher checks the answers together with the whole class, explains the mistakes that students often make, and strengthens their mastery of vocabulary and sentence patterns. Then, the teacher designs a translation exercise. Students need to translate Chinese sentences into English using the key sentence patterns. For example: 1. 小心别碰那个机器，它很危险。(Be careful not to touch that machine; it’s very dangerous.) 2. 你最好锁好门窗以避免被盗。(You’d better lock the doors and windows to avoid being stolen.) 3. 当心路上的冰，很容易滑倒。(Beware of the ice on the road; it’s easy to slip.) This exercise can test students’ ability to apply vocabulary and sentence patterns flexibly. Design Intention: Fill-in-the-blank and translation exercises are classic ways to consolidate vocabulary and sentence patterns. They can help students review the knowledge learned, find out their own weak points, and improve their ability to use language accurately and flexibly. Situational Simulation Practice The teacher divides students into groups of 4-5, and assigns different safety scenarios to each group, such as “safety in the laboratory”, “safety on the playground”, “safety in a shopping mall”, “safety at home” and so on. Each group needs to design a short situational dialogue or a small performance, which should include at least 3 key sentence patterns and 5 core vocabulary words of the unit. The dialogue or performance should reflect the safety hazards in the scenario and corresponding warning and prevention measures. Each group prepares for a few minutes, then performs in front of the whole class. After each performance, the teacher and other students comment on it, focusing on whether the vocabulary and sentence patterns are used correctly, whether the scenario is realistic, and whether the safety tips are reasonable. The teacher gives positive comments and puts forward suggestions for improvement. Design Intention: Situational simulation practice is closely combined with real life, which can make students apply the knowledge learned to practical communication scenarios, improve their oral expression ability and practical application ability. Group cooperation in the practice process can also cultivate students’ team spirit and cooperative learning ability. Reading and Writing Practice The teacher asks students to read a short passage about campus safety, which is similar to the reading material learned before but has some new safety tips. After reading, students need to write a short passage (about 100 words) titled “My Safety Tips for Campus Life”. The passage should include at least 2 safety hazards on campus and corresponding prevention measures, and use the key vocabulary and sentence patterns learned in the unit. When students are writing, the teacher walks around the classroom, provides help for students who have difficulties, and reminds students to pay attention to the correct use of vocabulary and sentence patterns, as well as the logic and coherence of the passage. After students finish writing, the teacher collects some representative compositions, reads them out in class, and comments on them, pointing out the advantages and disadvantages of each composition. Then, students exchange their compositions with their deskmates and revise them according to the teacher’s comments. Design Intention: Reading and writing practice can integrate reading and writing skills, improve students’ reading comprehension and written expression ability. Writing about campus safety can make students pay more attention to campus safety in real life, and realize the practical significance of learning this unit. Peer revision can help students find out their own mistakes and learn from each other, improving their writing level. Consolidation and Summary: Systematization of Knowledge First, the teacher invites students to summarize the knowledge learned in this class, including core vocabulary, key sentence patterns, and safety tips. The teacher supplements and sorts out students’ summaries, forming a complete knowledge framework on the blackboard, helping students systematize the knowledge learned. Then, the teacher reviews the key and difficult points of the unit again, emphasizing the correct use of vocabulary and sentence patterns, and the importance of applying safety knowledge to real life. The teacher also reminds students to pay attention to safety in their daily life and form good safety habits. Finally, the teacher assigns after-class homework: 1. Recite the core vocabulary and key sentence patterns of the unit. 2. Finish the reading and writing exercises in the workbook. 3. Discuss with family members about family safety hazards and write down 3 safety tips in English. 4. Collect 5 English safety slogans and share them in the next class. Design Intention: Letting students summarize independently can improve their ability to sort out and summarize knowledge. The teacher’s supplement and sorting out can help students form a systematic knowledge structure, deepening their understanding and memory of knowledge. After-class homework can consolidate the knowledge learned in class, extend the learning content to daily life, and realize the connection between classroom learning and real life. Assessment and Feedback: Promoting Learning through Assessment The assessment in this unit is divided into formative assessment and summative assessment. Formative assessment runs through the whole teaching process, including students’ performance in class discussions, pair practice, situational simulation, and the completion of in-class exercises. The teacher records students’ performance in time, gives positive feedback and guidance, and helps students find out their own problems and improve them in time. Summative assessment is carried out at the end of the unit, including a written test and an oral test. The written test mainly examines students’ mastery of vocabulary, sentence patterns, reading comprehension and writing ability. The oral test requires students to introduce a safety scenario and corresponding safety tips in English, examining their oral expression ability and practical application ability. After the assessment, the teacher analyzes the assessment results, summarizes the common problems of students, and carries out targeted review and guidance. At the same time, the teacher collects students’ opinions and suggestions on the teaching process, and adjusts the teaching methods and contents according to the feedback to improve the teaching effect. Design Intention: Formative assessment can timely reflect students’ learning progress and mastery of knowledge, helping the teacher adjust the teaching strategy in time and providing targeted guidance for students. Summative assessment can comprehensively examine students’ learning results of the whole unit, helping students understand their own learning level. The combination of formative assessment and summative assessment can promote students’ continuous progress and improve the teaching quality. 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 $
