Unit 7 Means of communication-C Grammaring 教学设计 2025-2026学年沪外教版英语八年级上册

Unit 7 Means of communication-C Grammaring This part of Unit 7 in the textbook focuses on the grammar related to means of communication. It mainly involves the usage of tenses in the context of talking about communication methods, such as the present perfect tense to describe experiences of using different communication tools, and the simple past tense to narrate past events about communication. Also, it may include the usage of relative clauses when referring to communication devices or concepts. For example, "The mobile phone which I bought last week is very useful for communication." These grammar points are crucial as they help students accurately express ideas about communication, both in speaking and writing. 教学目标 A. Knowledge Objectives Students will be able to master the key grammar structures related to means of communication, including the correct forms and usage of relevant tenses and relative clauses. They can identify and understand the grammar points when reading texts or listening to materials about communication. B. Ability Objectives Enable students to use the learned grammar to describe their own experiences with communication means, make comparisons between different communication methods, and express their views on the development of communication in oral and written forms. Develop students' ability to analyze and solve grammar - related problems, and improve their language application ability in various communication - related situations. C. Emotional Objectives Cultivate students' interest in learning English grammar through interesting teaching activities related to communication, which is closely related to their daily lives. Encourage students to actively participate in group discussions and pair - work, enhancing their sense of cooperation and communication skills. 教学重难点 A. Teaching Key Points The correct usage and formation of tenses, especially the present perfect tense and simple past tense, in the context of communication. For example, "I have used WeChat to communicate with my friends for a long time." and "I sent an email to my teacher yesterday." The understanding and application of relative clauses when describing communication means. Such as "The computer that I use for online communication is a new model." B. Teaching Difficult Points Helping students distinguish the subtle differences between the present perfect tense and the simple past tense in communication - related expressions. For instance, differentiating between "I have visited my pen - pal in the UK." (emphasizing the experience) and "I visited my pen - pal in the UK last summer." (emphasizing the past action at a specific time). Guiding students to correctly use relative clauses in complex sentences about communication, especially when dealing with different antecedents and relative pronouns. A. Tenses Present Perfect Tense Form: Have/has + past participle. Usage in communication context: To talk about experiences of using communication tools. E.g., "I have used video calls to see my grandparents who live far away." To express actions that started in the past and continue to the present in terms of communication habits. For example, "My father has used the landline for business communication since he started working." Simple Past Tense Form: Verb in the past form. Usage in communication context: To describe past events related to communication. Such as "She wrote a letter to her friend last month." To talk about specific communication actions that happened at a definite time in the past. E.g., "The company held a video conference yesterday to discuss the new communication plan." B. Relative Clauses Definition: A relative clause is a subordinate clause that modifies a noun or pronoun in the main clause. Usage in communication context: When referring to communication devices. For example, "The smartphone which has a high - quality camera is popular for taking pictures and sharing them immediately." When talking about communication concepts. Such as "The way that we communicate with each other has changed a lot in recent years." Relative Pronouns Who: Used for people. E.g., "The person who invented the telephone was Alexander Graham Bell." Which: Used for things. E.g., "The email which I received this morning is from my boss." That: Can be used for both people and things. E.g., "The device that helps us communicate wirelessly is a Wi - Fi router." 教学过程 A. Warming - up (5 minutes) Show some pictures of different means of communication, such as letters, telephones, mobile phones, and the Internet, on the PPT. Ask students to quickly name these communication tools and briefly describe their most recent experience of using one of them. For example, "I used my mobile phone to play an online game with my friends last night." This activity aims to activate students' prior knowledge about communication means and get them interested in the topic. B. Presentation (12 minutes) Present the grammar points related to tenses. Write two sentences on the blackboard: "I have sent many text messages this week." and "I sent a text message to my mom an hour ago." Explain the differences between the present perfect tense and the simple past tense in terms of meaning and usage. Use more examples related to communication, like "He has learned how to use WeChat Pay." (present perfect, emphasizing the result of learning up to now) and "He learned how to use WeChat Pay last month." (simple past, emphasizing the action happened in the past). Then, introduce relative clauses. Show a sentence: "The mobile phone is very important. I bought it last week." Combine these two sentences into one with a relative clause: "The mobile phone which I bought last week is very important." Explain the function of relative clauses and the usage of relative pronouns (who, which, that) with more examples about communication, such as "The person who taught me to use email is my English teacher." C. Practice (15 minutes) Tense Practice Hand out a worksheet with a series of sentences about communication. Some blanks need to be filled with the correct form of the present perfect tense or the simple past tense. For example: I ______ (send) an email to my pen - pal in the US yesterday. My sister ______ (use) WeChat to chat with her classmates since she got a new phone. Let students work individually first, and then check the answers in pairs. Walk around the classroom to offer help if necessary. Relative Clause Practice Present some sentences on the PPT and ask students to combine them into relative - clause sentences. For example: The computer is very fast. I use it for online learning. (Answer: The computer which I use for online learning is very fast.) The girl is my friend. She often helps me with my English by chatting online. (Answer: The girl who often helps me with my English by chatting online is my friend.) Divide students into groups of four to discuss and complete the tasks. Each group selects a representative to present their answers to the class. D. Production (10 minutes) Group Work Divide students into groups of five. Ask each group to create a short dialogue about communication. In the dialogue, they need to use at least three grammar points (tenses and relative clauses) that they have just learned. Give them some topics to choose from, such as "A discussion about the best communication tool", "Sharing experiences of communicating with foreigners", etc. After the groups finish creating the dialogues, ask each group to perform their dialogues in front of the class. The rest of the students listen carefully and pay attention to whether the grammar points are used correctly. Evaluation After each group's performance, let the other students give some comments. The teacher also gives comprehensive evaluations, praising the good points and pointing out the grammar mistakes if there are any. E. Summary and Homework (3 minutes) Summary Briefly review the key grammar points of this class, including the usage of tenses and relative clauses in the context of communication. Ask students to summarize in their own words what they have learned. Homework Ask students to write a short passage about the development of communication in their families. They should use at least five sentences with the grammar points learned in this class. Suggest students to search for more information about new communication technologies and be ready to share in the next class. 教学反思 After this class, I will first reflect on whether the teaching objectives have been achieved. Did students really master the grammar points related to communication means? I will judge this from their performance in class activities, such as the accuracy of filling in the blanks in the practice part and the correct usage of grammar in the group - work dialogues. If students still have difficulties in distinguishing between the present perfect tense and the simple past tense, I may need to design more specific exercises and create more vivid contexts in the next class to help them understand. For relative clauses, if many students make mistakes in using relative pronouns, I will review the rules in a more detailed and patient way, and provide more real - life examples for them to practice. Also, I will consider whether the teaching methods are appropriate. Were the group - work activities effective in promoting students' cooperation and communication? If some groups did not perform well, I will think about how to better organize group work in the future, such as giving more clear instructions and providing more guidance during the group - work process. In general, based on this teaching reflection, I will adjust my teaching strategies and methods to improve the teaching effect of grammar classes in the future. 2 / 37 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $
