Ask Ss one by one questions about the dialogue:
　　1) What did Jenny probably ask Mei Ge to do before they have the dialogue? (to find out the price for the IBM PC 486)
　　2) What does Jenny prefer to buy, PC 486 or PC 586? Why? (see book for the answer)
　　3) Why does Mei Ge want to buy the smaller one?
　　4) Why can’t they waste any more time? (price may go up and the factory needs the computers badly)
　　5) What is their final decision? (not mentioned)
　　2. Ask the next student to correct the mistakes if any
　　3. Give Ss one minute or two to go over the dialogue again and then ask one of the students to be Jenny and tell the others what has happened in the dialogue
One possible answer:
　　I am Jenny and I am working with Mei Ge in a factory. Our factory planned to buy a new computer so Mei Ge and I talked about buying a new computer. I asked Mei Ge to find out the price of the IBM PC 486 but I want to buy the IBM PC 586 because it is better and bigger. What’s more, we will change the 486 for 586 in a few years’ time. But Mei Ge still prefers the smaller one because he thinks it is a waste of money to buy a very good one. He believes PC 486 is good enough. We will meet again to make a decision the next day.
