　　"____________，"Li Ming said to his teacher.

　　A. Can you buy me a new watch？

　　B. Give me that book，

　　C. Lend me your bike，

　　D. Could you help me with my English？

　　S：I think D is the right answer.

　　T：Could you tell me why？

　　S：Because A is not logical. B and C are commands. In last period we learnt that commands should be made by people who have authority. So I think here D is right.

　　T：Your explanation is perfect.

　　Step 2 Talking （Workbook P48）

　　T：Great. Now let's practise the sentence patterns by making up dialogues. So please turn to P48 and look at the part of talking. Please work in groups of four. And choose one situation to role-play.

　　（5 minutes for preparation）

　　T：Now let's begin.

　　Possible version：

　　Group 1：

　　A.（foreigner）：Excuse me，could you give me a hand？

　　B：Sure. You seem to be looking for someone.

　　A：Yes. My Chinese friends and I promised to meet at the exit of the subway.

　　B：Could you speak a bit slowly. I can't quite follow you. I guess you are looking for your Chinese friends.

　　A：I'm sorry. I wasn't noticing it just now. Yeah，we said that we would meet here-the exit of the subway at 2 p.m. And it is 2：15，but I still can not find them.

　　B：Exit 1 or Exit 2？

　　A：What do you mean？There're 2 exits？

　　B：Yes. Here are two exits. So you should be sure which one is where you promised to meet.

　　A：I see. I am sure that they must be waiting for me at the other exit. Thank you very much!

　　Group 2：

　　（P：parents；W：waitress；Y：you）

　　P：Excuse me，could you tell me where the toilet is？

　　W：Er...the restroom？Well，go straight ahead，and it will be at the end of the corridor.

　　P：But we do not need rest. We are just looking for a toilet.

　　Y：I mean we want to go the WC.

　　W：WC？We don't have one.

Y：No WC! How can a restaurant have no WC？
