Let's do an exercise to see how to explain some words in English, according to the meanings of the sentences. Please turn to Page 5. Let's do the exercise in Word Study. Choose the closest meaning to the underlined word in each sentence. Before we do it, we'll learn a new phrase: use up. (Write it on the blackboard. And give some explanations and two examples. ) (Bb: use up He has used up all his strength. The boy has used up all the money for only three days. ) T: Are you clear about the use of “use up”? Ss: Yes. T: OK. Do the exercise by yourself. You can discuss it with your partner if necessary. I'll check the answer in a few minutes. T: (A few minutes later.) Now I'll ask some of you to give your answers. At the same time, translate the sentences into Chinese. (Teacher asks the students to do it one by one.)

(Bb.. 1. He hoped to visit China again. 2. It took a lot of time to finish the report. 3. Please give the boy something to play with. 4.He went home to see his sick mother. 5. Her wish is to become a pop singer. ) T: Now look at the sentences on the blackboard. And tell me the function of the underlined part in each sentence. Who'd like to do the first? (One students stands up.) S: Let me try. In the first sentence, “to visit China again” is used as the object. T: Good. The second, Ma Lu? S: In the second sentence, I think, “to finish the report” is used as the attribute modifying “time”. T: What he said is right or wrong? Ss: Wrong. It is used as the subject, not the attribute. T: Yes. “To finish the report” is used as the subject. It is more usual to use formal subject “it” and the infinitive phrase is usually placed at the end of the sentence, that is “it is … to do sth. .”Are you clear, Ma Lu? S: Yes. T: Now let's look at the third sentence. Any volunteer? S: “To play with” is used as the attribute. T: Is what she/he said right or wrong? Ss: Right. T: Yes. Look at the fourth sentence. Li Jia, you have a try. S: Here “to see his sick mother” is used as the adverbial for purpose. T: Good. Now look at the last sentence. Let's do it together. T and Ss: “To become a pop singer” is used as the predicative. T: Now you have known some usages of the infinitive. Let's do an exercise on the screen. (Show the exercise on the screen.)
