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 .

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.  Step 6 Practice Part 2      Ask the students to make similar dialogues to practise making suggestions and replying, using the phrases given. Pay particular attention to sentence stress and intonation.      Slide 4      Situation: One of your friends wants to keep fish, he/she wants to buy some golden fish and a fish tank. He/she would like to ask for advice from you. Now you'd like to advise him/her what to do.      Model:      A: Excuse me , would you please tell me what you are going to do?      B: I want to keep fish. I'd like to buy some golden fish. What should I do?      A: Oh, I suggest that you'd better go to the market. They are much cheaper there.      B: That's a good idea. But where should I keep them?      A: You should keep them in a large tank.      B: What size tank should I get?      A: You need to buy one about 30 cm by 30 cm by 50 cm.      B: Is that Ok?      A: You ought to put some large rocks in the tank.      B: Are they necessary?      A: You'd better put some underwater plants in it.      B:Why is that?      A: Because they keep the water clean and make the tank look more beautiful.      B: Thanks.      A: You're wele.      Then get the Ss to work in pairs.

He/she would like to ask for advice from you. Now you'd like to advise him/her what to do.      Step 7 Workbook      Finish Exx 1 and 3 orally, do Ex 2 as written work.      Ex. 1 revises the Object Clause. When transforming the structures,       pay attention to the change of the verb tenses, personal pronouns   and word order. After doing the exercises orally in class, ask the Ss to do it as written work.      Ex. 2 is a revision of the Modal Verbs and some useful expressions.       Let the Ss work in pairs and then check the answers with the whole class.       Write down the sentences on the Bb for the Ss to see.       Ex. 3 lists pairs of words with somewhat similar pronunciation       but different meaning. Get the Ss to read aloud the words and say what each of them means.      Step 9 Homework      Do Ex 2 in the exercise books.      Step 10 Blackboard Work      Unit 12Lesson 45      1.the other day = a few days ago      2. 30 cm by 30 cm by 50 cm.      the length 50 cm      the width 30 cm      the height 30 cm.      3.For one thing = one reason Making suggestions:      I suggest (that)      You should.      You ought to.      You need to.      You'd better.      PART 5 ments      Teachers should employ proper teaching methods and techniques to satisfy      their needs. They are in great need of instructions on how to be successful       language learners. Teachers should train them with some effective learning       strategies to optimize their learning results.      My lesson plan is designed on the basis of these two principles. The questions       in my teaching plan are raised for the purpose of arousing the students'       interests and aimed to help the students to concentrate on the meaning of the dialogue.      As for the language points, they are presented and practiced related to       students' life as much as possible. This way of teaching language points      is employed in the hope that students will find them easier to understand       and retain, and that they can use some of them immediately in their everyday life.       Dialogue Production is a solution to the problem of lacking chances to       practice English outside class. This activity can train the students with       this learning method. The teacher's encouragement and facilitation are necessary to make the students feel the happiness of success, so that they may want       to try more either in class or outside class in the future.
