Unit 3 Same or Different-Section A Grammar Focus 教学设计 2025-2026学年人教版（2024）八年级英语上册

Unit 3 Same or Different-Section A Grammar Focus This Grammar Focus section in Unit 3 of the 2024 PEP English textbook for Grade 8 focuses on the comparative forms of adjectives and adverbs. It equips students with the necessary grammar knowledge to compare people, things, and actions. By studying this section, students will be able to describe differences and similarities more accurately in their English expressions. The content includes the formation rules of comparative adjectives and adverbs, both regular and irregular, as well as the usage of the "as... as" structure for making equal comparisons. 教学目标 Students will be able to summarize the formation rules of comparative adjectives and adverbs, including regular changes like adding "-er" for one - syllable adjectives (e.g., tall - taller) and using "more" for most multi - syllable adjectives (e.g., beautiful - more beautiful), and also remember the irregular forms (e.g., good - better, bad - worse). Master the usage of comparative adjectives and adverbs in sentences, such as "A + be + adjective comparative + than + B" (e.g., Tom is taller than Jack) and "A + verb + adverb comparative + than + B" (e.g., She runs faster than her sister). Understand and correctly use the "as... as" structure to express equality, for example, "He is as tall as his father" and "She works as hard as her classmates". 教学重难点 1. Key Points The formation rules of comparative adjectives and adverbs, especially the differences between regular and irregular forms. The correct usage of comparative adjectives and adverbs in different sentence structures, and the understanding of the "as... as" structure. 2. Difficult Points Helping students correctly use adverbial modifiers like "much", "a little", etc., with comparative forms, such as "much taller", "a little faster". Avoiding common mistakes like double comparisons (e.g., more taller is incorrect). Also, enabling students to apply these grammar points fluently and accurately in real - life communication scenarios. 1. Comparative Adjectives Regular Changes One - syllable adjectives: Add "-er" to the end. Examples: tall - taller, short - shorter, fast - faster Adjectives ending with "e": Add "-r". Examples: nice - nicer, large - larger, fine - finer Two - syllable adjectives ending with "y": Change "y" to "i" and add "-er". Examples: happy - happier, friendly - friendlier, busy - busier Most two - syllable and multi - syllable adjectives: Use "more" before the adjective. Examples: beautiful - more beautiful, interesting - more interesting, expensive - more expensive Irregular Changes good - better bad - worse many/much - more little - less far - farther/further 2. Comparative Adverbs Regular Changes One - syllable adverbs: Add "-er" to the end. Examples: fast - faster, hard - harder Adverbs ending with "ly": Use "more" before the adverb. Examples: quickly - more quickly, slowly - more slowly, carefully - more carefully Irregular Changes well - better badly - worse 3. "As... As" Structure Used to show that two people or things are equal in a certain aspect. Structure: A + be + as + adjective + as + B (e.g., Lucy is as tall as Lily) A + verb + as + adverb + as + B (e.g., He runs as fast as his brother) 教学过程 1. Lead - in (5 minutes) Display some pictures of two people or things with obvious differences, such as two students with different heights, two animals with different sizes. Ask students questions like "Who is taller? Can you describe the picture using English?" Guide them to recall some simple comparative sentences they learned before, like "He is taller than her." This activity aims to arouse students' interest and review the basic concept of comparison, making a smooth transition to the grammar focus of this class. 2. Presentation (15 minutes) Work on 3a Ask students to read the sentences in 3a carefully and observe the bold - faced words. Then, divide them into small groups to discuss and try to summarize the rules for forming comparative adjectives and adverbs. After a few minutes, invite some groups to share their summaries. The teacher then elaborates on the rules, using more examples on the blackboard or PPT. For example, when explaining the rule of adding "-er" for one - syllable adjectives, write "tall - taller", "short - shorter", "strong - stronger" and ask students to give more similar examples. Explain the irregular forms of comparative adjectives and adverbs in detail. Write the irregular words and their comparative forms on the board and ask students to copy them in their notebooks, emphasizing the need to remember these special cases. Demonstrate how to use comparative adjectives and adverbs correctly through more example sentences. For instance, "The red car is faster than the blue one." and "She sings more beautifully than her sister." Let students pay attention to the sentence structure. 3. Practice (15 minutes) Work on 3b Organize students to complete the content of 3b through group cooperation. Each group is assigned a set of tasks. For example, one group needs to complete the sentences using the correct forms of the given adjectives, while another group focuses on adverbs. After they finish, ask students to read the completed sentences in different roles within the group. For example, one student reads the first part of the sentence, another reads the comparative part. This can help students better understand the context and usage of the comparative forms. Walk around the classroom during the group work, providing guidance and correcting students' mistakes in time. Work on 3c Show the pictures in 3c on the screen. Divide students into pairs. Each pair is required to discuss and summarize the differences between the two cities shown in the pictures. Then, ask them to fill in the blanks with the appropriate comparative forms of the given words. Encourage them to use complete sentences to describe the differences, such as "City A has a larger population than City B." Select several pairs to share their answers and descriptions with the whole class. Other students can ask questions or make comments. 4. Consolidation and Extension (8 minutes) Prepare some additional exercises on the PPT, including multiple - choice questions, sentence - making exercises, and translation exercises related to comparative adjectives, adverbs, and the "as... as" structure. Let students complete these exercises individually first, and then check the answers together. For the questions that students make mistakes frequently, explain them in detail, analyzing the reasons for the mistakes and strengthening the correct usage. For extension, ask students to think about and describe some differences and similarities between their hometown and another city they know, using at least three comparative sentences. They can share their descriptions with their partners. 5. Summary and Homework Assignment (2 minutes) Briefly summarize the key points of this class, including the formation rules of comparative adjectives and adverbs, and the usage of the "as... as" structure. Ask students if they have any questions. Assign homework: Ask students to write a short passage comparing themselves with one of their classmates, using at least five comparative sentences. Review the grammar knowledge learned in this class and preview the next part of the textbook. 教学反思 After this class, it is necessary to reflect on the teaching process and students' learning effects. In the lead - in part, most students were actively involved, which successfully activated their prior knowledge. However, during the presentation of grammar rules, some students seemed a bit confused, especially when dealing with irregular forms. Maybe more vivid and memorable ways could be used to help them remember, such as creating short stories or rhymes. In the practice section, group cooperation was generally effective, but some groups had unequal participation. In the future, more specific group roles could be assigned to ensure every student is engaged. Also, when checking students' answers in the exercises, it was found that some students still made mistakes in using adverbial modifiers with comparative forms. This indicates that more targeted practice and explanation are needed. Overall, through this reflection, adjustments can be made to improve the teaching quality in the following classes. 2 / 37 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $$
