Step III Practice the new vocabulary

Ask the students to explain in their own words the words in Section A in the workbook.

T: Very good. Please turn to Section A of workbook, the first part. Discuss these words in groups and explain their meanings in your own words.

Sample answers:

S1: Invent: There was not such a thing in the world. Someone made it and then there is such a

thing. So we can say someone invented it.

S2: Discover: There is a thing. But people don’t know it or few people know it. Someone find it and make it known to people. We can say someone discovers it.

S3: Scoop: When it is a noun, it means a short-handled tool for taking up and moving something. When it is a verb, it means lifting something with a scoop.

S4: Mistake: If I say 2 and 2 is 1, you can say I make a mistake.

S5: Annoying: make one angry, unhappy or uncomfortable.

S6: Adjustable: that can be made more helpful or useful.

S7: Microwave: very short wave.

S8: Braces: something used to tighten.

Ask the students to circle the words in the table.

T: Very good. Now please find these words and circle them in the table. Volunteers?

Show a hanging chart with the same table to the students. Ask them to come to the front and circle the words in the table in the hanging chart.

Check the answers and correct the mistakes if there are any.

Step IV Words about food taste(1a, 1b: P71)

Ask one student to come to the front to do a blind taste test.

Show a bag to the students.

T: Look, there are 4 kinds of food in it. I will let one of you come to the front and taste them. But I will use a piece of cloth to cover his or her eyes. After tasting, he or she has to tell how each food tastes and what food it is. Are you clear? Sophie, please.

Cover Sophie’s eyes and give her the food one by one. Sophie tastes each foo d and tries to guess what it is.

S: It is sweet. I think it is an apple.

They are salty and crispy. I think they are potato crisps.

It is sour. I think it is a tomato.

It is salty. But I don’t think I have eaten this food before. It is delicious.

T: Do you enjoy the food? Now you can take off the cloth. The last one is Pizza, which is popular with westerners. You can take it with you and go back to your seat. Thank you.

Sophie goes back to her seat.

T: Hi, class. What are the four different tastes of the food Sophie had?

S: They are sweet, crispy, salty and sour.

T: Yes. They are words used to describe different tastes of food. Try to use them to describe the food in the picture of 1a, Section B.

Ask the students to read the pictures of 1a in Section B and describe how the food tastes.

T: Now, look at the four pictures. What are they?

Ss: They are potato chips, lemon, ice cream and tea.
