Unit 3 Historical Events-Language Focus 2 教案-2025-2026学年高中英语人教版选修第一册

Unit 3 Historical Events-Language Focus 2 内容导航 This section focuses on the key vocabulary, phrases and complex sentence structures related to historical events. It helps students master the usage of past perfect tense and passive voice in the context of historical events, and improve their ability to express historical processes and their influences in English. 教学目标和重难点 1. 教学目标 Language Ability: Master core vocabulary (e.g., troop, tank, revolutionary) and phrases about historical events, and skillfully use past perfect tense and passive voice to express historical contexts. Cultural Awareness: Understand the historical backgrounds and cultural connotations of major historical events at home and abroad, respect cultural diversity and enhance historical consciousness. Thinking Quality: Cultivate logical thinking through analyzing the cause-effect relationship of historical events and critical thinking through evaluating historical influences. Learning Ability: Master effective methods of vocabulary and grammar learning, and improve autonomous learning and cooperative inquiry ability in group activities. 2. 教学重难点 Key Points: Master the usage of past perfect tense (expressing actions completed before a certain past time) and passive voice (describing historical events objectively) in the context of historical events; memorize and use core vocabulary and phrases related to historical events flexibly. Difficult Points: Distinguish the usage of past perfect tense and simple past tense in historical narration; correctly use passive voice in different sentence structures to describe historical events accurately and fluently; apply the learned language knowledge to express historical views and feelings. 教学过程 Step 1: Lead-in (Warm-up and Activation) Activity 1: Historical Picture & Sentence Matching The teacher shows pictures of typical historical events (e.g., the founding of the People's Republic of China, the Industrial Revolution, the American Revolution) on the screen. Each picture is matched with two sentences: one uses simple past tense, and the other uses past perfect tense. Students are asked to work in pairs to match the pictures with the correct sentences and discuss the differences between the two tenses. After the discussion, invite 2-3 groups to share their answers and explain their reasons. Design Intention: This activity starts with visual pictures to arouse students' interest in historical events, activate their existing knowledge of simple past tense, and naturally lead to the key grammar point of this lesson - past perfect tense. Through pair discussion, students can initially perceive the difference between past perfect tense and simple past tense in the context of historical events, laying a foundation for the formal teaching of grammar. Activity 2: Vocabulary Activation The teacher presents the core vocabulary of this lesson (troop, tank, warrior, revolutionary, breakthrough, defeat, victory, announce, witness, occur) on the screen, with English definitions and simple example sentences related to historical events. For example, "troop: a group of soldiers; The troops were sent to the front line to fight for the country." Students read the words and example sentences aloud together, then work in groups to make one simple sentence with each word, combining their own understanding of historical events. The teacher walks around to guide students, corrects their mistakes in sentence making, and asks some students to share their sentences in front of the class. Design Intention: Vocabulary is the foundation of language learning. By presenting vocabulary with definitions and historical context example sentences, students can better understand the meaning and usage of words. Group sentence making not only helps students consolidate the memory of vocabulary but also enables them to initially connect vocabulary with historical events, laying a foundation for the subsequent application of language knowledge. Step 2: Presentation (Key Knowledge Explanation) 2.1 Vocabulary and Phrases Presentation The teacher focuses on explaining the key vocabulary and phrases that are difficult for students to master, combining the context of historical events. For example, for the word "revolutionary", the teacher explains its part of speech (adjective and noun), meaning ("relating to a revolution; a person who takes part in a revolution") and usage, and gives examples related to historical events: "The revolutionary movement changed the fate of the country. Many revolutionaries devoted their lives to the pursuit of freedom." For key phrases (e.g., take place, break out, in memory of, come to an end, play a key role in), the teacher explains their meanings and usages, and contrasts similar phrases. For example, compare "take place" and "break out": both mean "to happen", but "break out" is usually used for unexpected events (such as wars, fires), while "take place" is used for planned events. Examples: "The First World War broke out in 1914. The opening ceremony of the Olympic Games will take place in Beijing." After the explanation, the teacher gives students 5 minutes to read the vocabulary and phrases again, and asks them to mark the words and phrases they find difficult to remember. The teacher then answers students' questions and summarizes the memory skills, such as associating words with historical events or making word groups (e.g., revolutionary - revolution - revolve). Design Intention: Focusing on difficult vocabulary and phrases can help students break through the learning bottleneck. Combining historical context examples makes the explanation more vivid and easy to understand. Contrasting similar phrases helps students avoid confusion and use them correctly. Allowing students to mark difficult points and ask questions can improve the pertinence of teaching and meet the individual learning needs of students. 2.2 Grammar Presentation: Past Perfect Tense First, the teacher reviews the simple past tense with students, and then presents two sentences related to historical events on the screen: ① The war ended in 1945. ② Before the war ended, many people had lost their homes. The teacher asks students to observe the two sentences and discuss the following questions: What is the time relationship between the two actions in sentence ②? What is the difference between the verb tenses used in the two sentences? After the discussion, the teacher summarizes the definition of past perfect tense: It is used to express an action that was completed before another action or a certain time in the past. The structure is "had + past participle". The teacher then explains the signal words of past perfect tense, such as before, by the time, by 1990, when, after, etc., and gives examples combined with historical events: "By the time the People's Republic of China was founded in 1949, the Chinese people had suffered a lot from wars. Before Columbus discovered America, many people had thought the earth was flat." Next, the teacher focuses on the distinction between past perfect tense and simple past tense: Simple past tense expresses an action that happened at a certain time in the past, while past perfect tense expresses an action that was completed before another past action or time. The teacher uses a time axis to help students understand: draw a time axis on the blackboard, mark a past time point (e.g., 1945), an action completed before this time point (e.g., many people lost their homes) uses past perfect tense, and an action happening at this time point (e.g., the war ended) uses simple past tense. Finally, the teacher gives some practice sentences, and asks students to fill in the blanks with the correct form of the verbs. For example: ① By 1910, the country ______ (already, become) a modern nation. ② When we arrived at the historical site, the meeting ______ (end). Design Intention: Starting from the review of simple past tense, students can smoothly transition to the learning of past perfect tense. Through observing and discussing sentences, students can independently summarize the definition and usage of past perfect tense, which is more conducive to their understanding and memory. Using a time axis can visually show the time relationship between actions, helping students distinguish past perfect tense and simple past tense. Timely practice can consolidate the learned grammar knowledge and detect students' understanding. 2.3 Grammar Presentation: Passive Voice in Past Tense The teacher presents sentences related to historical events on the screen: ① The government built many schools after the war. ② Many schools were built by the government after the war. The teacher asks students to compare the two sentences and find out the differences in structure and meaning. Then, the teacher summarizes the definition of passive voice: It is used to emphasize the object of the action or when the doer of the action is unknown or not important. The structure of passive voice in simple past tense is "was/were + past participle", and in past perfect tense is "had been + past participle". The teacher explains the usage of passive voice in the context of historical events: When describing historical events, passive voice is often used to emphasize the event itself rather than the doer, making the expression more objective and formal. For example: "The Declaration of Independence was signed in 1776. Many cultural relics had been destroyed before the government took measures to protect them." Then, the teacher explains the steps of converting active voice to passive voice: ① Find the object of the active sentence and make it the subject of the passive sentence; ② Change the verb to the corresponding passive form; ③ Keep the adverbial of time, place, etc.; ④ If the doer of the action needs to be emphasized, add "by + doer" at the end of the sentence. The teacher gives examples to demonstrate the conversion: Active: The workers built the Great Wall in the Qin Dynasty. Passive: The Great Wall was built by the workers in the Qin Dynasty. After the explanation, the teacher asks students to work in pairs to convert the active sentences about historical events into passive sentences. For example: ① The soldiers defended the city bravely. ② The scientists had made great progress in the research by the end of last century. Design Intention: By comparing active and passive sentences, students can intuitively understand the structure and function of passive voice. Combining historical events to explain the usage of passive voice makes students realize the practical significance of passive voice in actual communication. Pair conversion practice can help students master the conversion method proficiently and improve their ability to use passive voice flexibly. Step 3: Practice (Consolidation and Application) 3.1 Vocabulary and Phrases Practice Activity 1: Fill in the Blanks with the Correct Words/Phrases The teacher presents a passage about a historical event (e.g., the Industrial Revolution) with some blanks. The words and phrases provided include the core vocabulary and phrases of this lesson (e.g., breakthrough, take place, play a key role in, revolutionary). Students are asked to complete the passage independently. After completing, students check their answers with their deskmates. The teacher then explains the key points and difficult points in the passage, especially the usage of words and phrases. Sample Passage: The Industrial Revolution ______ in Britain in the 18th century. It was a ______ change that ______ the development of the world. Many technological ______ were made during this period, which ______ improving people's living standards. Design Intention: This activity integrates vocabulary and phrases into a coherent passage about historical events, helping students consolidate the usage of words and phrases in context. Independent completion and pair checking can not only improve students' autonomous learning ability but also enhance their communication and cooperation ability. Activity 2: Word Formation Exercise The teacher presents some root words related to historical events (e.g., revolve, victory, defeat) and asks students to form new words according to the word formation rules (e.g., prefixes and suffixes). For example, revolve → revolutionary, victory → victorious, defeat → defeated. Students work in groups to complete the exercise and share their answers. The teacher summarizes the common word formation rules and encourages students to use these rules to expand their vocabulary. Design Intention: Word formation is an important method for students to expand their vocabulary. By this exercise, students can master the common word formation rules, improve their ability to guess word meanings, and lay a foundation for their future English learning. 3.2 Grammar Practice: Past Perfect Tense Activity 1: Multiple Choice The teacher presents 10 multiple-choice questions, focusing on the usage of past perfect tense and its distinction from simple past tense. The questions are closely related to historical events. For example: ① By the time he arrived at the historical museum, the exhibition ______. A. began B. had begun C. has begun D. begins ② The old man told us that he ______ in this city for 50 years before he moved to the countryside. A. lived B. has lived C. had lived D. lives Students complete the questions independently, then the teacher checks the answers and explains the reasons for each question, focusing on the signal words and time relationship of past perfect tense. For the questions that students often make mistakes, the teacher gives extra examples to strengthen their understanding. Design Intention: Multiple-choice questions can quickly detect students' mastery of grammar knowledge. Combining historical events makes the questions more vivid and close to the teaching content. Explaining the reasons in detail helps students correct their mistakes and deepen their understanding of past perfect tense. Activity 2: Sentence Making with Signal Words The teacher writes the signal words of past perfect tense (before, by the time, by 2000, when, after) on the blackboard. Students are asked to make one sentence with each signal word, combining historical events. For example, with "before": Before the Second World War broke out, many countries had tried to maintain world peace. Students work independently, then share their sentences in front of the class. The teacher comments on their sentences, corrects mistakes, and praises excellent sentences. Design Intention: This activity helps students master the usage of past perfect tense with signal words, and improves their ability to apply grammar knowledge to actual sentence making. Sharing and commenting can enhance students' confidence in speaking English and promote their mutual learning. 3.3 Grammar Practice: Passive Voice Activity 1: Rewrite Sentences into Passive Voice The teacher presents 8 active sentences about historical events, and asks students to rewrite them into passive voice, paying attention to the tense (simple past tense and past perfect tense). For example: ① The ancient people built the Pyramids in Egypt. ② The government had protected the historical site before it was damaged. Students complete the exercise independently, then the teacher collects some students' answers and writes them on the blackboard, comments on them, and emphasizes the key points of conversion (e.g., the change of verb form, the retention of adverbial). For the common mistakes (e.g., forgetting to use "was/were" or "had been", wrong past participle form), the teacher gives targeted guidance. Design Intention: This exercise focuses on the conversion between active and passive voice, helping students master the structure and usage of passive voice proficiently. Targeted guidance on common mistakes can help students avoid making the same mistakes again and improve their accuracy in using grammar. Activity 2: Complete the Passive Voice Passage The teacher presents a passage about the history of the Great Wall, which is written in passive voice with some blanks. Students are asked to fill in the blanks with the correct form of the verbs (simple past tense or past perfect tense of passive voice). For example: The Great Wall ______ (build) by the ancient Chinese people. It ______ (repair) many times before it became a world cultural heritage. After completing, students read the passage aloud together. The teacher checks the answers and explains the key points, helping students understand how to use passive voice in a coherent passage. Design Intention: This activity integrates passive voice into a coherent passage, helping students master the usage of passive voice in context and improve their ability to apply grammar knowledge comprehensively. Reading aloud can enhance students' sense of language and improve their pronunciation and intonation. 3.4 Comprehensive Practice Activity: Group Discussion and Report The teacher divides students into groups of 4-5, and assigns each group a historical event (e.g., the founding of the People's Republic of China, the Industrial Revolution, the French Revolution). Each group is required to discuss the following questions: ① When and where did the event take place? ② What caused the event? ③ What happened during the event? ④ What influence did the event have on the world? During the discussion, students are required to use the vocabulary, phrases and grammar knowledge learned in this lesson (past perfect tense, passive voice). After the discussion (about 10 minutes), each group sends a representative to give a 3-5 minute report in front of the class. The teacher evaluates the reports from the aspects of language accuracy (vocabulary, grammar), fluency, and content completeness, and gives positive comments and suggestions for improvement. Design Intention: This comprehensive practice integrates vocabulary, phrases and grammar knowledge, and combines listening, speaking, reading and writing skills. Group discussion can improve students' cooperative inquiry ability and communication ability. Report presentation can enhance students' oral expression ability and confidence. The teacher's evaluation can help students find their own advantages and disadvantages and improve their language application ability. Step 4: Consolidation and Extension 4.1 Summary The teacher leads students to summarize the key content of this lesson: ① Core vocabulary and phrases related to historical events, and their usage; ② The definition, structure, signal words and usage of past perfect tense, and its distinction from simple past tense; ③ The structure and usage of passive voice in past tense, and the conversion between active and passive voice. The teacher emphasizes that students should flexibly use the learned knowledge to describe historical events and express their views. Design Intention: Summarizing the key content can help students sort out the knowledge system of this lesson, strengthen their memory of the learned knowledge, and improve their ability to summarize and induce. 4.2 Extension Activity The teacher assigns an after-class task: Ask students to choose a historical event they are interested in, write a short passage (about 150 words) to introduce the event, using the vocabulary, phrases and grammar knowledge learned in this lesson (at least 3 core words, 2 phrases and 2 sentences using past perfect tense or passive voice). Students are required to collect relevant information about the historical event before writing. In addition, the teacher recommends some English materials about historical events (e.g., English historical documentaries, short articles on historical events) to students, and encourages them to read and watch in their spare time to expand their knowledge and improve their English reading and listening ability. Design Intention: The after-class writing task can help students consolidate the learned knowledge and improve their written expression ability. Collecting information can cultivate students' autonomous learning ability. Recommending English materials can expand students' horizons and create a good English learning environment for them. 4.3 Error Correction and Feedback In the next class, the teacher collects students' after-class writing tasks, checks them carefully, records the common mistakes (e.g., wrong usage of vocabulary and phrases, incorrect tense, wrong passive voice structure), and explains these mistakes to students in class. For the excellent compositions, the teacher reads them aloud in class and encourages other students to learn from them. Students are asked to correct their own mistakes and rewrite their compositions if necessary. Design Intention: Error correction and feedback can help students find their own mistakes in time, correct them, and avoid making the same mistakes again. Showing excellent compositions can stimulate students' learning motivation and improve their writing level. Step 5: Emotional Education and Value Guidance At the end of the lesson, the teacher guides students to think about the significance of learning historical events in English: Learning historical events in English can not only improve our English language ability but also help us understand the historical and cultural background of different countries, broaden our horizons, and cultivate our historical consciousness and global vision. The teacher encourages students to learn from history, cherish the present life, and strive to become people who can contribute to the development of the country and the world. Design Intention: Combining language teaching with emotional education and value guidance can realize the goal of "moral education in all subjects", help students establish correct values, and cultivate their sense of responsibility and mission. 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 $
