Teaching Advice
Lead-in
Look and Say Show students some different pictures, and then ask them to make comparisons and give their reasons.Here are two examples. ◆The teacher can show students pictures of a cheetah and a horse, and then ask“Which animal runs faster,a cheetah or a horse？” ◆The teacher can show students pictures of playing basketball and football, and then ask “Which sport is more popular in our class, basketball or football？” Revision Tell students they are going to compare people now.Review the different aspects they can use to compare people. Choose two students and ask other students to compare the two students from their appearances, personalities, habits and strengths. Teaching Tip：Remind students that when comparing people, focus on their strengths and positive qualities.For example, instead of saying “Student A is shorter than Student B”, they can say“Student B is taller than Student A”． Think and Say Write the sentences that students make on the blackboard.Ask if they can find the common features of these sentences.The teacher can use the following questions as prompts： ◆Look at these sentences.What do you notice about the adjectives(and adverbs)？Do they change in any way ◆What word do we use to connect the two things being compared Tell students that we use the comparative form to compare two people or two things. 比较级表示两者(人或事物)的比较。由“比较级＋than”的句型构成，意思是“……比……较为……”。
Explore the Grammar
3a 1.Ask students to read the sentences and notice the comparatives in bold.Then find more examples in Section A． 2.Ask students to divide the words in bold into three categories：words that add “ er”，words that end with “ ier” and words that use “more”．Ask students to add more words which use “more”． 3. Let students read the words and think about the following questions. ◆Look at the words which add “ er”．What do you notice about the number of syllables in these words ◆What happens to the spelling of words like “funny” and “lazy” when we add “ ier”？ ◆Why do we use “more” with words like “colourful” and “interesting”？ ◆So，can you find any rules for forming comparatives？Discuss with your partners.

Grammar Exercises
3b Ask students to read the sentences and the words in brackets.Then ask them to write the comparative forms of the adjectives and adverbs. Let them use the words in brackets to write questions and answers. 3c 1.Ask students to look at the chart.Make sure they can read and understand all the information. 2.Have them use the words in the box and than to complete the sentences to compare Guangzhou and Vancouver. 3.Encourage students to make more sentences to compare Guangzhou and Vancouver using the information in the chart. E.g.The population of Guangzhou was (much) larger than that of Vancouver in 2024. Guangzhou rains more than Vancouver every year. If you don't like the cold weather，it's a better choice to visit Guangzhou in January. Extension Exercises Option 1：The teacher can ask students to work in pairs and take turns to be a tour guide and a tourist.The tour guide should compare Guangzhou and his/her hometown to help the tourist decide which city to visit. Option 2：The teacher can also ask students to correct the mistakes of some comparative sentences.
Summary Ask students to summarize the forming rules of comparatives. Homework Finish the related exercises in the books produced by Youyi. Blackboard Design Write the forming rules of comparatives on the blackboard.
Teaching Reflection
After teaching this lesson, I noticed that students were good at using comparatives in simple comparison sentences.Most of them could use “than” to compare two things correctly.However, they had trouble with comparative change rules.They often made mistakes because they didn't fully grasp the rules for forming comparatives.To help them improve, I will add more related class exercises and assign more targeted homework.
