Unit 4 Epic engineering-C Grammaring 教学设计 2024-2025学年沪外教版英语七年级下册

Unit 4 Epic engineering-C Grammaring This part of "C Grammaring" in Unit 4 "Epic engineering" mainly focuses on the grammar usage of "although" and "though". It helps students understand how to use these two conjunctions to express contrast in sentences. Through various examples related to engineering works, students will not only learn the grammar rules but also get a deeper understanding of the challenges and solutions in epic engineering projects, which links grammar learning with the theme of the unit. 教学目标 A. Knowledge Objectives Students will be able to understand the meaning and usage of "although" and "though" to express contrast. Students can correctly identify and use "although" and "though" in different sentence structures. Master the common patterns and positions of "although" and "though" in sentences. B. Ability Objectives Improve students' reading and comprehension ability by analyzing sentences with "although" and "though". Develop students' writing skills to correctly use these conjunctions to connect ideas in writing. Enhance students' oral communication skills, enabling them to use "although" and "though" appropriately in daily conversations when expressing contrast. C. Emotional Objectives Cultivate students' interest in grammar learning through interesting engineering - related examples. Encourage students to be brave in facing challenges just like engineers by learning about the difficulties and solutions in epic engineering projects while studying grammar. 教学重难点 A. Key Points The usage and differences between "although" and "though" in expressing contrast. How to correctly place "although" and "though" in sentences, either at the beginning or in the middle. Understanding the logical relationship expressed by "although" and "though" in context. B. Difficult Points Helping students distinguish the subtle differences in the usage of "although" and "though", especially in spoken English where "though" is more commonly used and often combined with "even". Training students to use "although" and "though" accurately in complex sentence structures and avoid common mistakes. Meaning: "Although" and "though" both mean "in spite of the fact that", used to introduce a subordinate clause that contrasts with the main clause. Usage in sentence structure: They can be placed at the beginning of a sentence. For example, "Although/Though it was a difficult task, Chinese engineers and workers did their best to overcome the challenges." They can also be placed in the middle of a sentence. For example, "The workers managed to complete the project on time, although/though they faced many difficulties." Differences: "Though" is used more often in speech. We often use "even" with "though" (but not with "although"). For example, "Even though he tried hard, he failed to solve the problem." 教学过程 A. Lead - in (5 minutes) Show some pictures of famous epic engineering works, such as the Great Wall, the Qinghai - Xizang Railway, and the Grand Canal. T: "Boys and girls, we have learned a lot about epic engineering works in this unit. Look at these pictures. Can you name these amazing engineering works?" Let students answer briefly. Then, ask students to think about the challenges these engineering works faced during construction. T: "When building these great projects, engineers and workers must have faced many challenges. Can you guess some of the challenges?" Encourage students to share their ideas, like difficult terrain, bad weather, lack of advanced technology, etc. Present some simple sentences on the blackboard or PPT, for example: "Engineers worked hard. There were many challenges." "The dam was built a long time ago. It is still used to stop floods." T: "Now, I want you to think about how we can combine these two sentences to show the contrast between the two facts. Discuss with your partners." Let students discuss in pairs for about 2 minutes. B. Presentation (10 minutes) After the discussion, ask some pairs to share their combined sentences. T: "OK, who would like to share your combined sentences?" Write down some of the students' answers on the blackboard. Then, introduce the usage of "although" and "though". T: "Today, we are going to learn two very useful words to express contrast - 'although' and 'though'. Look at the correct way to combine these sentences. For example, 'Although/Though engineers worked hard, there were many challenges.' or 'The dam was built a long time ago, although/though it is still used to stop floods.' " Explain the meaning and basic usage of "although" and "though" in detail, using more examples related to engineering works. For example, "Although the terrain was tough, the workers still built the railway successfully." "Though the weather was challenging, the engineers didn't give up." Compare the positions of "although" and "though" in sentences (at the beginning and in the middle) and show the examples again for students to observe. C. Practice (15 minutes) Exercise 1: Sentence completion Present some incomplete sentences on the PPT, such as: "__________ it takes a long time to build a park, it will give us a nice place to play and relax." "The workers continued to work on the site, __________ they faced many difficulties." "__________ the material was expensive, the engineers still chose it for its high quality." Let students fill in the blanks with "although" or "though". Walk around the classroom to check students' work and offer help if necessary. After students finish, ask them to read out their answers one by one. Exercise 2: Sentence combination Provide a set of two - sentence groups on the worksheet. For example: Group 1: "The bridge was very long. The engineers managed to build it in a short time." Group 2: "They didn't get any help from abroad. They completed the project independently." Ask students to combine each group of sentences using "although" or "though". Students can work individually first, and then exchange their answers with their deskmates for peer - checking. Select several students to write their combined sentences on the blackboard for class discussion. Exercise 3: Oral practice Divide the class into pairs. Each pair is given a topic related to engineering or daily life, such as "Building a tall building" or "Doing homework". Students need to make up short conversations using "although" and "though" to express contrast. For example, if the topic is "Building a tall building": A: "Building a tall building is very difficult." B: "Yes, although there are many challenges, engineers always find ways to solve them." A: "Though the cost is high, the building will be very useful when it is completed." Walk around the classroom to listen to students' conversations and give guidance on pronunciation, intonation, and grammar usage. After about 5 minutes, invite some pairs to perform their conversations in front of the class. D. Consolidation (10 minutes) Reading comprehension Present a short passage about an epic engineering work on the PPT. The passage should contain several sentences with "although" and "though". For example: "The Qinghai - Xizang Railway is an amazing epic engineering project. Although the construction environment was extremely harsh, with high altitude and freezing weather, the engineers and workers were determined to complete it. They faced many technical challenges, though they never gave up. Even though the construction period was long, they finally managed to build this 'Heavenly Road', which has greatly promoted the development of Tibet." Ask students to read the passage carefully and then answer some questions related to the content and the usage of "although" and "though". For example: Q1: What challenges did the engineers face during the construction of the Qinghai - Xizang Railway? Q2: Find two sentences that use "although" or "though" in the passage and explain the contrast they express. Let students read the passage silently for 2 - 3 minutes, and then answer the questions. Discuss the answers as a class. Writing practice Ask students to write a short paragraph about an epic engineering work they know. They need to use "although" or "though" at least twice in their paragraphs to describe the challenges and achievements. Give students some hints on the PPT, such as the name of the engineering work, its main functions, and some possible challenges. For example: Name of the work: The Three Gorges Dam Main functions: Generate electricity, control floods, improve shipping conditions Possible challenges: Massive construction scale, environmental impact, relocation of a large number of people Students write their paragraphs individually. After they finish, ask them to exchange their writing with their group members (4 - 5 students in a group) for peer - review. Group members can give each other suggestions on grammar, content, and organization. Then, each student can revise their paragraph based on the suggestions. Select several students to read their paragraphs aloud to the class. E. Summary and Homework Assignment (5 minutes) Summary Review the key points of "although" and "though" with the students, including their meaning, usage, and differences. T: "Today, we learned about the usage of 'although' and 'though' to express contrast. Remember, 'although' and 'though' can be placed at the beginning or in the middle of a sentence. 'Though' is more commonly used in spoken English, and we can use 'even' with 'though'. Can you give some examples?" Invite several students to give examples to reinforce the knowledge. Homework Assignment Ask students to find at least three English articles or short passages (from textbooks, English newspapers, or online resources) that contain "although" or "though". Underline the sentences with these conjunctions and write a short summary of the contrast expressed in each sentence. Students are also required to write a short story about an imaginary engineering project. They need to use "although" and "though" at least three times in the story to make it more vivid and logical. 教学反思 After this 45 - minute class, overall, the teaching objectives were basically achieved. Most students showed a good understanding of the usage of "although" and "though" through various practice activities. The lead - in part, by showing pictures of epic engineering works and discussing challenges, successfully aroused students' interest and connected grammar learning with the unit theme. However, there were still some areas that needed improvement. During the practice exercises, some students had difficulty in using "although" and "though" correctly in complex sentence structures. For example, in the sentence combination exercise, some students made mistakes in word order or used the wrong form of verbs. This indicates that more targeted practice on complex sentence structures is needed in future classes. Also, in the oral practice, a few students were a bit shy and did not actively participate in the conversations. In the future, more encouragement and more diverse oral practice activities should be designed to make every student more involved. In the reading comprehension and writing practice, students' performance was relatively good. But some students' writing content was a bit monotonous. Teachers can provide more detailed writing guidance and rich examples in the future to help students enrich their writing. Overall, through continuous improvement of teaching methods and more targeted practice, students' grammar - using ability can be further enhanced. 2 / 37 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $
