Task 2 New usage of the -ing formAsk the students to look at Exercise 4 on Page 20. And then work in pairs to finish the Exercise. In order to make sure the quality, the teacher can ask some of the students to explain some of the phrases in the Exercise.T: Now let’s finish the Exercise 4 on Page 20. I’ll give one minute for you to check your answers. Because you have done this in the homework, I think one minute is enough. And then I’ll choose some of them to let you explain. But before doing this you’d b etter pay attention to the example. In the example, we can use for ... phrase or an attributive to explain the -ing phrases. Are you clear?Ss: Yes.T: Ok, do the Exercise now.One minute later.T: Well, what does cooking pot mean?S1: A pot that is used for cooking.T: What does operating table mean?S2: A table for operating.T: What does drinking horse mean?S3: It means a horse that is drinking water.T: It seems that you have master the usage of the -ing form as attribute. Now, let’s look at the Exerci se1 on Page 21. What does it tell us to do?S4: It tells us to find the sentences in the reading passage where the -ing form isused as the object complement.T: Can you find some?S4: Yes. In fact we have done this work in the last period. But I don’t und erstand what object complement means.T: This is a good question. The object complement is used to explain what object has done, or doing, or to do. Or we can think that the speaker wants to express his/her meaning more completely. Of course, in this unit we only study the -ing form as the object complement. The structure of the sentence with an object complement is: (Show the following on the screen.)Subject + Predicate + Object + Object complementAre you clear now?S4: Yes.T: Now, let’s look at Exercise 2. Have you done this?Ss: Yes.T: Ok, now let’s check the answers for this Exercise. Who would like to say your answers out?Teacher can ask 9 students to read the 9 complete sentences to check the answers. If there are some questions, teacher should give students some explanations, and make some changes if there are some incorrect answers.T: Well, can you analyze the part of speech of the -ing form in the 9 sentences? S5: In the first three sentences the -ing form is used as object complement.T: Right. Have you found the same structure in other sentences?S5: Yes. In the fifth, the sixth, the seventh, the eighth and the ninth sentence, the -ing form is also used as the object complement.T: How about the rest?S5: In the fourth sentence, the -ing form is used as the attribute.T: Quite right. Now I think we can go on to do Exercise 3. Let me see if you have finished this Exercise.Teacher walks around, the students are asked to check their answers.T: I’m very glad that most of you have finished the exercise. But some of you need to be more deligent. Next time I’ll specially check your answers. Well, the structure of the sentences has been given. Can you tell me the structure?S6: Yes, I can. The words in the left column are the subject. The -ing forms in the middle column are the attribute. And the words in the right column the words are used as the predicate, and so on.T: Right. Now I’d like you to read out one of your sentences and then translate it. Who can?S7: The boy climbing the mountain is a friend of my brother. 爬山的那个男孩儿是我哥的一个朋友。
