Step4 Oral practice
A
A has long hair.
B has long hair, too.
B
→ A has longer hair than B .
Work out the rule
（1）when we compare two things , we use ） comparatives, and we put “than” after the comparatives, we usually add “er” to short adjectives and use “more” for long adjectives. e.g. She is shorter than I am. My book is more interesting than his book.
（2）There are also some other rules. If the ） word: a. Ends with “e”, we add “r” directly. b. Ends in a consonant +“y”, we exchange “y” to “i” , add “e r”. c. End in a vowel + a consonant, double the consonant, add “e r”. d. Special adjective, good---better, bad---worse. Please look at the table on Page 13 carefully.

Step1.Part A 1. Lead-in :
We have learned many adjectives, but do you know how to use to describe people and things? Think about it, and you can look at Page12 to consult it. I’ll see who is clever.
Consolidation:
Do the exercises on Page 13, B1. comparative, than ask you to answer, also speak out why you change this.
Step3.Part B Superlatives
We use comparatives when we compare two things, but when we compare three or more people/things, how do we say?
2.Presentation: The girl’s hair is longer than any other girl in class. The girl’s hair is the longest in class.
Work out the rule
a.when we compare more than three things, we can use superlatives, we usually add “est” to short adjectives and use “most” for long adjectives, than 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.
2. Presentation
① We use adjectives to describe people and things, which puts before a noun or after a link verb and look at the examples on the book. ② Analysis, “She has short hair”, “hair” is the noun. “short” is the adjective, according to the rule, put the adjective before the noun, so we put short before hair. Ask a student to analysis the second sentence. ③ Look at the sentence “Her hair is short”, before the adjectives is a linking verb. We can use adjective after these linking verbs. Such as : be , become, feel, get, grow…… ④ Call you to analysis the sentence “The cat is lazy.”
3. Consolidation: Do part A on Page12. Remember that put an adjective before a noun or after a link verb, then find the subject and predicate to make sentence. Read them and translate them.
1.Ask you to compare their classmates, using comparatives and superlatives. 2.Practice in groups, let the students compare things/people around them , then I’ll ask 1-2 groups to speak it out.
There are also some other rules. If the word:
A. Ends with “e”, we add st” B.Ends in a consonant+ “y”, we exchange “y” to “i” , add “est” C.End in a vowel + a consonant, double the consonant, add “est” D. Special adjective, go---best, bad---worst Please look at the table on Page 13 carefully.
Step2.Part B Comparatives 1.Lead-in : We learned to use the adjectives to describe things. But if we compare two things, how do we say? And you want to compare with your friends, how do you say?
