Module 3 Life now and then-Unit 3 Language in use 一、教学目标 Language Ability: Proficiency in vocabulary about life changes (e.g., "technology", "lifestyle") and flexible use of comparative/superlative structures. Cultural Awareness: Recognizing global variations in past-present life transitions to build intercultural empathy. Thinking Quality: Synthesizing information to compare life aspects logically and form balanced judgments. Learning Ability: Applying grammar (comparatives, superlatives, modal verbs for opinions) in integrated tasks. 二、重难点 Accurately using comparative/superlative forms of adjectives/adverbs, including irregular ones. Combining opinion phrases ("I believe", "It seems") with comparative structures coherently. Producing structured texts/dialogues analyzing life differences with clear reasoning. 三、教学过程 教学环节 教师活动 课内探究 复习导入 T（Teacher）：Good morning, class! Let's start today's lesson by reviewing what we've learned in Unit 1 and Unit 2. Who can tell me the key grammar points we practiced? S（Student）1：We learned how to use comparative forms to compare life now and then, like "better", "wealthier". T：Exactly! What else? S2：We also used "used to" to talk about past habits, such as "People used to light homes with candles". T：Perfect! Today we'll focus on using these language points in different contexts. Let's look at some pictures first. (Show pictures of 1990s classrooms vs. modern classrooms) Describe the differences using comparative forms. S3：Modern classrooms are brighter than 1990s classrooms. S4：There are more computers in modern classrooms than in 1990s ones. T：Excellent! Now let's practice turning these observations into full sentences with "used to" and comparatives. 语法巩固练习 T：Open your workbooks to Page 45. Let's do Exercise 1 together. Fill in the blanks with the correct comparative forms. The first one: "Cities are ______ (crowded) now than 50 years ago." S5：More crowded. T：Correct. Next: "People's houses are ______ (big) today than in the past." S6：Bigger. T：Good. Now Exercise 2: Rewrite sentences using "used to". Example: "I lived in a small village. Now I live in a city." → "I used to live in a small village, but now I live in a city." Let's try the first one: "She walks to school. Ten years ago she took the bus." S7：She used to take the bus to school, but now she walks. T：Well done! Let's check Exercise 3 in pairs. You have 3 minutes to complete the dialogue with "used to" or comparatives. (Students work in pairs. After 3 minutes...) T：Let's role-play the dialogue. Who wants to be Tom? And who will be Lucy? (S8 and S9 act out the dialogue.) T：Wonderful! You used "used to" and comparatives correctly. Remember: "used to" describes past states that no longer exist, while comparatives show differences between two times. 听力理解训练 T：Now let's listen to a radio interview about family life changes. First, read the questions on the screen. (Show questions: 1. How many children did families usually have 50 years ago? 2. What did parents used to do for entertainment? 3. Are families closer now than before?) (Play the recording once.) T：Who can answer Question 1? S10：Families usually had more children 50 years ago—often 3 or 4. T：Correct. Question 2? S11：Parents used to play board games or tell stories in the evening. T：Yes. And Question 3? S12：No, the interviewer says families are not as close now because everyone is busy with phones. T：Excellent listening! Let's listen again and underline all the "used to" phrases and comparatives in the transcript. (Distributes transcripts) (Students underline phrases while listening. Then check together.) T：Look at this sentence: "Meals used to be a time for talking, but now people watch TV instead." What's the structure here? S13：It uses "used to" and "instead" to contrast past and present. T：Exactly! This is a useful way to show differences. 小组合作任务 T：Now let's do a group project. In groups of 4, create a poster comparing "Weekends Now vs. 30 Years Ago". Include 4 categories: Activities, Food, Transportation, Communication. Use at least 5 comparatives and 3 "used to" sentences. You have 15 minutes. (Students discuss and design posters. Teacher circulates to assist.) T：Time's up! Let's present. Group 1, please. Group 1 Representative：Our poster shows... (Presents using phrases like "People used to visit relatives on weekends, but now they travel further. Trains are faster than before..." ) T：Fantastic! You clearly compared the two time periods. Group 2? (Group 2 presents with similar structure.) T：Wonderful use of "more convenient" and "less expensive". All groups did great—your posters really show language in use! 写作练习指导 T：Now let's write a short paragraph: "The Biggest Change in My Hometown". Use these prompts: 1. What was it like 10 years ago? 2. What is it like now? 3. Why is this change important? Remember to use comparatives and "used to". (Students write for 8 minutes. Teacher checks papers individually.) T：Let's share. S14, please read your paragraph. S14：My hometown used to have small houses. Now there are tall buildings... It's better because there are more jobs. T：Great! Can we make it stronger? Let's add "much taller" instead of "tall" to emphasize the difference. Who wants to try revising? S15：My hometown used to have small houses, but now there are much taller buildings. It's better because there are more job opportunities than before. T：Perfect! Adding "much" and "opportunities" makes it more precise. 综合应用练习 T：Turn to Page 50, Exercise 6. Complete the survey about life changes, then interview your partner. Use questions like "Did your parents use to...?" and "Is... better now than before?". (Students survey each other. Then share results.) S16：My partner's dad used to ride a bike to work, but now he drives a car. He thinks cars are faster but less healthy. T：Excellent! You're using the language naturally. Remember, language in use is about communication, not just rules. 错误分析与总结 T：Let's look at common mistakes. (Shows sentences on screen: 1. "I am used to live in a village." 2. "Today is more hot than yesterday.") What's wrong here? S17：First sentence should be "I used to live"—"am used to" is for habits, not past states. S18：Second sentence: "hotter" instead of "more hot". T：Exactly! "Used to + verb" for past actions; one-syllable adjectives add "-er" for comparatives. T：Today we practiced comparatives and "used to" through speaking, listening, and writing. Remember: compare carefully, use "used to" for past habits, and always think about how language works in real communication. 作业布置 T：For homework: 1. Write a 100-word email to a pen pal describing how your daily life is different from your grandparent's. 2. Make a list of 5 things your family "used to" do that you miss. 3. Prepare for tomorrow's speaking test: Compare two photos of your school—2000 vs. 2025. Class dismissed! See you tomorrow. 思维延伸 课堂小结： 老师：通过今天的学习，我们了解了数形结合的思想，并且学会了用数形结合的方法来解决一些实际问题。数形结合不仅可以帮助我们更直观、更简单地理解问题，还可以帮助我们更准确地计算答案。希望大家在以后的学习中，能够灵活运用数形结合的思想和方法来解决问题。 巩固提升 学生讨论小结，互相补充回忆巩固本节课知识，进一步夯实基础提升能力。 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 $$
