Unit 3 Same or Different-Section A-Grammar Focus
【教学目标】
Language Competence: Master comparative/superlative adjectives/adverbs and "as...as" structures, applying them in sentences.
Cultural Awareness: Recognize how English-speaking cultures use grammatical comparisons to express attitudes (e.g., modesty vs. emphasis).
Thinking Quality: Analyze grammar rules through examples, differentiate regular/irregular forms, and justify usage logically.
Learning Ability: Acquire strategies to memorize exceptions (e.g., good→better) and practice via context-based tasks.
【教学重难点】
Key Points: Formation of comparative/superlative (e.g., +er/est, more/most), "as + adj./adv. + as", and irregular forms (e.g., bad→worse).
Difficult Points: Correct use of comparative markers (than) and adverbial modifiers (much/a little), avoiding double comparisons (e.g., more braver). Apply grammar in real-life comparisons fluently.
【教学过程】
Teacher: Hello, class! Welcome back to English class. Today, we are going to focus on an important part of our Unit 3, which is the Grammar Focus. We've been talking about comparing people and things, right Like who is taller, who is more outgoing. Now, let's dig deeper into the grammar rules behind these comparisons.
First, let's take a look at the sentences on the screen.
Teacher reads the sentences from Grammar Focus:
Is Tom smarter than Sam No, he isn't. Sam is smarter than Tom.
Is Tara more outgoing than Tina No, she isn't. Tina is more outgoing than Tara.
Are you as friendly as your sister No, I'm not. I'm friendlier.
Does Tara work as hard as Tina Yes, she does.
Who's more hard - working at school Tina thinks she works harder than me.
Teacher: Now, class, I want you to pay attention to the words in bold. These are what we call comparatives. They are used to compare two people or things. Let's start with the basic rule. For most one - syllable adjectives, we add - er to the end to make the comparative form. For example, 'tall'. If we want to compare the height of two people, we say 'taller'. Can you give me some other one - syllable adjectives and make their comparative forms Raise your hands.
Student 1: 'Short', it becomes'shorter'.
Teacher: Great! Very good. What else
Student 2: 'Fast', it's 'faster'.
Teacher: Excellent! You got it. Now, for some two - syllable adjectives that end with - y, we change the - y to - i and then add - er. Take 'friendly' as an example. Instead of 'friendlier', we say 'friendlier'. Can you think of another one like this
Student 3: 'Lazy', it becomes 'lazier'.
Teacher: Exactly! You are all so smart. Now, there are some two - syllable or more - syllable adjectives where we don't add - er. Instead, we use'more' before the adjective. For example, 'outgoing'. We say'more outgoing'. What about 'beautiful' How do we make its comparative form
Student 4: More beautiful.
Teacher: Perfect! Now, let's move on to the sentences structure. When we want to compare two people using adjectives, we use the structure 'A + be + adjective comparative + than + B'. Look at the sentence 'Sam is smarter than Tom'. Here, Sam is A, Tom is B, and'smarter' is the comparative form of'smart'. Can you make a sentence like this using other adjectives Work with your partner for a minute and then share your sentences with the class.
(Students work in pairs)
Teacher: Okay, time's up. Who wants to share their sentence
Student 5: My brother is taller than me.
Teacher: Good job! That's a great sentence. What about someone else
Student 6: My cat is fatter than my neighbor's cat.
Teacher: Very creative! Now, let's talk about another structure. When we want to say that two people or things are equal in some way, we use 'as + adjective or adverb original form + as'. For example, 'Are you as friendly as your sister ' Here, we are comparing the level of friendliness. Can you give me an example using this structure
Student 7: My bag is as big as yours.
Teacher: Excellent! Now, let's look at adverbs. Adverbs also have comparative forms. Some adverbs follow the same rules as adjectives. For example, 'fast' can be used as an adjective and an adverb. 'He runs faster than me.' Here, 'faster' is the comparative form of the adverb 'fast'. But some adverbs, especially those ending in - ly, we use'more' to make the comparative. For example, 'carefully'. The comparative is'more carefully'. Can you make a sentence using a comparative adverb
Student 8: She writes more carefully than her brother.
Teacher: Great! You really understand this. Now, let's do some exercises to practice what we've learned. Look at the first question on the worksheet.
(Teacher goes through the exercises on the worksheet, asking students to answer and explaining the answers)
Teacher: For the first question, it says 'Is your father _ (tall) than your mother ' What should we fill in here
Student chorus: Taller.
Teacher: Correct! And for the second one, 'My sister sings _ (beautifully) than I do.'
Student 9: More beautifully.
Teacher: Exactly! Now, let's look at this sentence: 'I think math is _ (difficult) than English.' What do we put in the blank
Student 10: More difficult.
Teacher: Perfect! You are all doing a wonderful job. Now, let's play a little game. I'll describe two people or things, and you tell me which one is greater or better using the correct comparative form. Are you ready
Teacher: I have two apples. One is small, and the other is big. Which one is bigger
Student chorus: The big one is bigger.
Teacher: Good. Now, I have two students. One studies hard, and the other studies very hard. Which one studies harder
Student 11: The one who studies very hard studies harder.
Teacher: Excellent! Let's do one more. I have two runners. One runs fast, and the other runs very fast. Which one runs faster
Student chorus: The one who runs very fast runs faster.
Teacher: Great! You all seem to have a good grasp of this grammar point. Now, let's do a group activity. In your groups, compare the three of you in terms of different aspects like height, personality, hobbies, etc. Use the comparative forms we've learned. Then, each group will choose one person to come to the front and share your comparisons with the whole class.
(Students work in groups)
Teacher: Okay, time's up. Group 1, who would like to come and share your comparisons
Student 12 from Group 1: In our group, I am taller than Student 13, but Student 14 is the tallest. Student 13 is more outgoing than me, and Student 14 is the most outgoing. In terms of hobbies, I like reading more than Student 13, and Student 14 likes painting more than both of us.
Teacher: Wonderful! That's a very detailed comparison. Group 2, your turn.
Student 15 from Group 2: We compared our schoolwork. I work harder than Student 16, but Student 17 works the hardest. Student 16 is as friendly as me, but Student 17 is the friendliest.
Teacher: Great job, Group 2. You all did a fantastic job in this activity. Now, let's summarize what we've learned today. We learned about the comparative forms of adjectives and adverbs, how to make them, and how to use them in sentences to compare two people or things. Remember the rules: for one - syllable adjectives, usually add - er; for two - syllable adjectives ending in - y, change - y to - i and add - er; for most two - syllable or more - syllable adjectives, use'more'; and for adverbs, some follow the same rules as adjectives, while those ending in - ly usually use'more'. Also, we learned the sentence structures 'A + be + adjective comparative + than + B' and 'as + adjective or adverb original form + as'.
For homework, I want you to write a short paragraph comparing yourself with your best friend. Use at least five comparative sentences. I'm looking forward to reading your paragraphs tomorrow. That's all for today's class. Class is dismissed.
