Grammar I: Describing things with adjectivesT: When we use adjectives to describe someone or something, we can put an adjective before a noun or after a link verb.E.g. She has short hair. Her hair is short. A lazy cat is sleeping on the sofa. The cat is lazy.T: We can use adjectives after these link verbs, like “be, become, feel, get, grow, keep, look, seem, smell, sound, taste, turn”E.g. look smart, get green, smell goodDo you understand how to use adjectives?Ss: Yes.T: Please give me some examples.S1: He has a round face. His face is round.S2: She wears short skirt. Her skirt is short.S3: .T: Students can understand how to use adjectives.

(Ask students to think of more examples.) But if we want to compare two people /things, we should use comparatives of adjectives. If we want to compare three or more people/things, we should use superlatives of adjectives. Do you know comparatives and superlatives?Ss: Sorry.T: Next lets learn about comparatives and superlatives.Step IV. Grammar II: Comparatives and superlatives.T: Comparatives of adjectives: When we compare two people /things, we usually use comparatives of adjectives. We usually add “-er” to short adjectives and use “more” for long adjectives. Then we add “than” after the comparatives.E.g. She is shorter than I am. My book is more interesting than his book.Sandys hair is longer than Millies hair.T: Superlatives of adjectives: When we compare three or more people/things, we usually use superlatives of adjectives. We usually add “-est” to short adjectives and use “most” for long adjectives. Then we add “the” before the superlatives.E.g. He is the tallest boy in my class. This is the most expensive printer in the shop.T: What should we know when we use comparatives and superlatives?Ss: We should know the comparatives and superlatives of adjectives.T: Good! So now I will show you a table to show how we form comparatives and superlatives with adjectives in detail. We should master the rules.Show the table to Ss.
