8A Unit 1 Grammar Ⅰ
Teaching objectives
1. To use an adjective before a noun or after a linking verb to describe someone/something
2. To use comparatives and superlatives to compare people/things.
Teaching procedures
Grammar A
Step 1 Lead-in
1. Review some useful adjectives by asking students to describe a girl’s appearance
with adjectives. Then read the description together with the class.
2. Tell the students that this lesson we’ll go on to learn describing someone or
something with adjectives. Ask them if they know how to describe someone or something with adjectives. Then start to learn Grammar A..
Step 2 Learning for use
Show a picture of a lovely girl. Tell the students the girl is lovely and encourage them to think of another way to express the same meaning: She is a lovely girl. Then show some other pictures and help students to put an adjective before a noun or after a linking verb to complete the sentences.
Step 3 Rule out
1. Ask the class to read the sample sentences carefully and try to find out where we should put an adjective in a sentence when we use them to describe things. The teacher can divide the sentences into two groups to help them.
2. Work out the rule together with the students. Tell them that we use adjectives to
describe someone or something. We can put an adjective before a noun or after a
linking verb such as the verb ‘be’.
Step 3 Practice
1. Ask the students to do some practice!
1. ‘He is a strong man.’ means ‘The man is strong.’
2. ‘Tom’s hair is long.’ means ‘Tom has long hair.’
3. ‘He has small eyes.’ means ‘His eyes are small.’
4. ‘This book is interesting.’ means ‘This is an interesting book.’
2. Ask the students to open their books at page 12 and help Daniel rearrange the words
to form complete sentences. Then check answers with the whole class.
T&Ss: Millie has short hair. / Sandy wears round glasses. / Amy is funny and cheerful. / Millie does not like long hair. / Sandy is tall and has long hair.
Step 5 Rule out
1. Go through the rules about adjectives again. Then invite students to think of more linking verbs.
2. Show some linking verbs that we often use to the students and ask them to read together: be, become, feel, get, grow, keep, look, seem, smell, sound, taste, turn.

Step 6 Practice
Ask students to make sentences using these linking verbs with adjectives.
The teacher can offer some adjectives. The students can choose some of these linking
verbs to make sentences with them. Of course, they can make sentences with other
adjectives if they like.
Grammar B
Step 1 Lead-in
Use pictures of two girls to elicit examples with comparative forms.
Linda is taller than Nancy is.
Nancy is shorter than Linda is.
Then ask students to guess the meaning.
Step 2 Learning for use
1. Show pictures of two bags and compare their price.
S: The green bag is 50 yuan. The pink one is 100 yuan.
Tell the students ‘The green bag is cheaper than the pink one.’ or ‘The pink bag is more expensive than the green one.’
2. Ask the students to look at the sentences again and read them together.
Linda is taller than Nancy is. / Nancy is shorter than Linda is.
The green bag is cheaper than the pink one. / The pink bag is more expensive than
the green one.
Step 3 Rule out
1. Ask the students to look at these sentences carefully and try to find out some rules
of comparatives through them. They can talk about this with their partners.
2. Try to elicit the rule from students, e.g., we use comparatives to compare two people or things. We usually add ‘-er’ to short adjectives and use ‘more’ for long adjectives. Then we add ‘than’ after the comparatives.
3. Ask students to complete the two model sentences using comparatives.
She is shorter than I am. / My book is more interesting than his book.
4. Ask students if they know what is a short adjective and what is a long adjective. Ask them to read Part B on Page 12 and try to find the answer.
5. Explain that short adjectives are adjectives of one or two syllables such as ‘clean’ and ‘heavy’. Long adjectives are adjectives of three or more syllables such as ‘interesting’ and ‘beautiful’.
Encourage them to think of more short adjectives and long adjectives.
Step 4 Learning for use
1. Add another girl – Kate to the picture of Nancy and Linda to elicit examples with superlative forms.
Elicit the answer from students ‘Linda is the tallest girl of the three.’ / ‘Kate is the shortest girl of the three.’
2. In the same way, add another bag to the two bags and help students to get the right superlative form.
‘The green bag is the cheapest one of all the bags.’
Ask students to talk about the purple one. Ask them if we can add ‘-est’ to ‘expensive’
too.
Explain that ‘cheap’ is a short adjective while ‘expensive’ is a long adjective.
We add ‘-est’ to short adjectives to compare three or more people or things.
Obviously, we can’t add ‘-est’ to the word ‘expensive’. We should use ‘most’ for long
adjectives.
So, we should say like this: The purple bag is the most expensive one of all the bags.
Step5 Rule out
1. Ask students to put two model sentences into Chinese.他是我们班最高的男生。/ 这是这家商店最贵的一台打印机。
Point out that we call the parts marked in yellow superlatives of adjectives.
2. Go through when we should use comparatives with the class. Then ask students when we should use superlatives. Elicit the rule from students that we use superlatives to compare three or more people/things. we usually add ‘-est’ to short adjectives and use ‘most’ for long adjectives. Then we add ‘the’ before the superlatives.
3. Ask how we can form comparatives and superlatives with different adjectives.
Tell students to read the table on Page 13 and find the answer. Then go through the table and check understanding.
Point out the exceptions. ‘Good’ and ‘bad’ are two of the special adjectives. We form their comparatives and superlatives in a different way.
Then ask them to use the right forms of good and bad to complete the sentences.
1) I’m better at English than at Chinese.
2) His handwriting is the worst of all the students.
Step 6 Practice
Ask students to turn to Page 13 and do Part B1. Help Daniel write the comparatives and superlatives of these adjectives:
funny-funnier-funniest, good-better-best, happy-happier-happiest
interesting-more interesting-most interesting, large-larger-largest
smart-smarter-smartest, thin-thinner-thinnest
