Step 4 Dialogue Presentation

The teacher’s brief introduction

Today we will learn a dialogue about keeping fish. Kate and Li Qun are talking about it. Now read the dialogue silently and find out the answers to these questions:

(A few large rocks and some underwater plants)








2. The first listening

A. Listening and answering

Play the tape for the Ss to listen. Go through the dialogue briefly. Ask questions

Slide 3

Why should Kate put a few large rocks in the tank?

( Because fish love swimming round the rocks and through holes in them.)

Why should Kate put some underwater plants in the tank?

( Because the underwaer plants can keep the water clean and make the tank look much prettier.)








Allow the Ss a few moments to carry out the task. Check the answers.



3. The second listening

A. Listening and explanation

Play the tape again.Let the Ss listen the second time. While listening, I explain the language points. Make sure the Ss understand it.

a. the other day = a few days ago

b They don‘t get enough air:

With a bowl, only a small surface area of the water is in contact with the air. So the water does not receive enough oxygen.

c 30 cm by 30 cm by 50 cm.

We describe two-dimensional and three-dimensional measurements using the word by. So the length of the tank is 50 cm, and the width and height both 30 cm.

e underwater plants:

These plants oxygenate the water and keep it clean.

d For one thing = one reason (for putting plants in the tank)



Step 5 . Practice and deep understanding

a. Following

Let the Ss listen and follow the dialogue,then I ask a few pairs to act the scene in front of the class.

b. Question

Why should Kate get a large tank to keep the fish in?

(With a bowl, only a small surface area of the water is in contact with the air. So the water does not receive enough oxygen.)

c. Moral lessons

Keeping fish or birds or keeping any other animal can bring us happiness and enjoyment. It can cultivate our healthy hobby. So we must love these animals. They are our good friends. We are living on the earth happily together.

If the animals die out, it will cause dying out of human being, like the dying out of dinosaur. I mean disappear throughly from the earth. Not only the mankind but also everything in the world. Much more, the earth will also be destroyed. what a horrible thing! We must protect our environments and keep the balance of the nature.
