Unit 2 Great people Grammar 教学设计 I. Teaching Objectives Enable students to master the usages of simple present, present continuous, simple past, past continuous, and present perfect tenses, including their functions and sentence structures. Improve students’ ability to choose the correct tenses in different contexts through practice, preparing for exam - related grammar tasks. Enhance students’ awareness of tense consistency and accuracy in expressing actions and states, which is crucial for effective communication and exam success. II. Language Knowledge 1. Key Tense Structures Simple present: Used for present states, daily routines, scheduled actions, and general truths. Example: “John lives in New York. I always go to bed at 10 p.m.” Present continuous: Used for actions happening now, simultaneous actions, temporary actions, and future arrangements. Example: “The reporter is interviewing the astronaut. I am leaving for Shanghai tonight.” Simple past: Used for past actions, sequential past actions, and past actions at a specific time. Example: “Simon played football yesterday. Simon came home, turned on the computer and checked his email.” Past continuous: Used for past actions in progress, simultaneous past actions, and past actions with duration. Example: “Yesterday at 4 p.m., Simon was playing football. Simon was playing computer games while Millie was watching TV.” Present perfect: Used for emphasizing past action results, and actions happening multiple times till now. Example: “Qian Xuesen and his team have saved millions of people’s lives. Jing Haipeng has been to space three times.” 2. Key and Challenging Points Tense Functions: Clearly distinguishing the uses of each tense, especially the differences between simple past and present perfect. Contextual Application: Choosing the correct tense based on context in written and spoken communication. Exam - related Practice: Applying tense knowledge to complete exercises similar to exam questions, such as sentence transformation and error correction. III. Teaching Procedures Step 1: Lead - in & Review (5 minutes) Show pictures of actions happening in different time frames (e.g., a student studying now, a student playing football yesterday). Ask students to describe the actions using different tenses. Quick review: Write sentences on the board and ask students to identify the tenses (e.g., “I play football every day.” — simple present; “She is reading a book now.” — present continuous). Step 2: Presentation of Simple Present & Present Continuous (10 minutes) Structure Explanation: Use Section A to explain the functions and structures of simple present and present continuous tenses. Highlight signal words (e.g., always, often for simple present; now, at the moment for present continuous). Give more examples: “He works in a factory. (simple present, daily routine)” “They are building a new school. (present continuous, action happening now)” Exercise Practice (Section A): Do “We enjoy the modern life!” exercise. Students complete the article with correct tenses. Walk around to help with tense choice, especially for future arrangements (e.g., “I am leaving for Shanghai tonight.”). Check answers and explain common mistakes. Step 3: Presentation of Simple Past & Past Continuous (12 minutes) Structure Explanation: Use Section B to explain simple past (for completed past actions, sequential actions) and past continuous (for actions in progress, simultaneous actions). Emphasize signal words (e.g., yesterday, last night for simple past; at this time yesterday, while for past continuous). Give examples: “I saw a movie yesterday. (simple past)” “While I was sleeping, my brother was playing games. (past continuous)” Exercise Practice (Section B): Do “What did you do last night?” exercise. Students complete the conversation with correct tenses. Discuss answers, focusing on tense consistency in simultaneous actions (e.g., “Simon was playing computer games while Millie was watching TV.”). Step 4: Presentation of Simple Past & Present Perfect (10 minutes) Structure Explanation: Use Section C to explain the differences between simple past (past actions at a specific time) and present perfect (emphasizing results, actions till now). Highlight signal words (e.g., in 2019 for simple past; already, so far for present perfect). Give examples: “He landed on the Moon in 2019. (simple past)” “They have saved millions of people’s lives. (present perfect)” Exercise Practice (Section C): Do “Great inventions” exercise. Students choose correct words to complete the article. Guide them to analyze context (e.g., “Fresh food would go bad... The invention of the fridge has solved this problem.” — present perfect for result). Check answers and clarify tense uses. Step 5: Comprehensive Practice & Exam Link (5 minutes) Mixed Tense Practice: Create sentences with mixed tenses and ask students to identify and correct mistakes. For example: “I am watching TV yesterday. (Correct: I watched TV yesterday.)” Have students write short paragraphs using different tenses to describe a day, including past, present, and future actions. Exam - style Questions: Show simple exam - like grammar questions (e.g., sentence transformation: “He went to Beijing last year. → He has been to Beijing.”). Let students practice and explain tense transformation rules. Step 6: Summary & Homework (3 minutes) Summary (1 minute): Recap the key tenses: simple present, present continuous, simple past, past continuous, present perfect. Emphasize their functions and signal words. Homework (2 minutes): Ask students to write a short story (100 - 150 words) using at least three different tenses. Review the tense structures and prepare for a small quiz next class. IV. Assessment of Teaching Effectiveness Formative Assessment: Observe students’ participation in exercise practices (A, B, C), checking for understanding of tense uses. Evaluate students’ sentence - making in comprehensive practice for accuracy. Summative Assessment (for later): Check homework stories for correct tense application in different contexts. Use quiz results to assess mastery of tense structures and exam - related application. V. Design Purpose Gradual Learning: Breaks down tense teaching into categories, making complex grammar manageable. Textbook - Centered: Fully uses textbook exercises to ensure students grasp content while connecting to real - life and exam scenarios. Application - Oriented: Practices tense usage in writing stories, enhancing practical language skills for exams and communication. VI. Blackboard Design Unit 2 Great people Grammar — Tenses 1.
