3.Study the language items in the lesson. Step I Warming--up The teacher asks the students the questions: Do you keep animals? If yes, what kind of animal do you keep? Do you find keeping animals interesting? Tell us something important about keeping fish, birds or other animals. Divide the class into four groups. Give them a few minutes for the discussion. Then collect answers from the class. Get several students to report their discussion. The teacher sums up and says, “Today, we are going to learn Lesson 45. In the dialogue, two friends, Kate and Li Qun, are talking about keeping fish.” Step II Watching Page 67. Part one. Read the introduction to the dialogue aloud. Ask the Students to cover the dialogue silently and quickly to find out the answer to the question: What does Li Qun advise Kate to do? Allow them a few moments to carry out the task. Check the answer. Get a large tank to keep the fish. Step III Listening Books closed. Present more questions before playing the tape: Where does Kate want to keep the fish? What’s wrong with keeping fish in a bowl? What size tank should she get? What should she put in the tank, Play the tape of the dialogue. Get another 4 students to give out the answers. ——In a round bowl. The fish can’t get enough air in a bowl. She should get one about 30 centimetres by 30 cm by 50 cm. A few large rocks and some underwater plants. Step ⅣLanguage points A. the other day = a few days ago B. So are the fish; the fish are small, too. C. 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 any oxygen. D.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 clear. F. for one thing = one reason (for putting plants in the tank) Step V Practice Page 67. Part 2. Write the question on the Bb: What should I do to keep a dog / a cat, etc.? Ask the Students to choose a specific kind of animal, and offer their suggestions by using the following expressions: I suggest (that) … You should … You ought to… You need to… First the teacher practises the dialogue with a good student as an example. Then the class do it in pairs. Get 2 pairs of students to come to the front and demonstrate their dialogues. Do similar practice using the words and phrases in part 2. (责任编辑：admin) |
