C： That's not true.
D： You have a skirt in that bag which you haven't paid for.
C： I think you have made a mistake.
D： Would you please come back inside the store and explain.
C： Right.
(They go back inside the store and go to the skirt department. )
D： This skirt, Madam. You did not pay for it and you took it out of the store.
C： You're right. I didn't pay for it because I didn't buy it. I only changed it.
D： You say you changed it?
C： Yes. It was the wrong size. It was a Christmas present from my sister, so I brought it back today and changed it for a larger size.
D： Madam. Here is the skirt which you said was too small. Would you look at this label inside the pocket, please? Do you see this date on the label?
C： Yes.
D： It's yesterday's date. So this means that this skirt was brought into the store yesterday.
Not before Christmas.
C： I expect someone made a mistake.
D： Yes, Madam, you made the mistake. I saw you take this skirt from the skirt department. Then you walked around the store and went up to the second floor. While goingup the stairs I saw you put the skirt into an old M & S bag. Then later you went back to the ground floor and asked to change this skirt.

Step 4 Speaking
SB Page 54, Part 2. Check the forms： go through the expressions for expressing possibility and impossibility and check that Ss know how to form complete sentences. Write up some cues on the Bb： pass /fail /go/come back/buy/send/hire/spend. Ask Ss to complete the expressions given in this part. Point out that It is possible that and It is likely that are rather more formal and impersonal than the others. Situation： Demonstrate this activity by talking about situation 1. If you like, you can say： Where's X? He may be at home. He may just be late. It's possible that he's had an accident on his way to school. Or he may not be well.

Step 5 Workbook
Wb Lesson 84, Exx. 1 - 2.
Ex. 1 provides four situational dialogues in which the expressions about possibility and impossibility in Lesson 84, Part 2 may be used. Ask the Ss to do it in pairs first. Then call out some pairs to give their dialogues and discuss the answers. Ex. 2 should be done individually first so that everybody makes an effort to extract the relevant information from the reading passages in this unit. Then call out some Ss to read aloud the whole passage.
Step 6 Checkpoint
Go through the Grammar study section in the previous lesson. Revise the Attribute, especially if any Ss had difficulties, and deal with any language points that you or the Ss wish to raise.
