[高一]Unit 2 In the lab Lesson7(人教版)

Step 1. Checking the retelling and the exercises of the workbook.
Step 2. Presentation
Show the students some instructions.
Example:
(1) Open the door.(2) Close the windows.(3) Sit down.
Ask them whether these instructions are polite enough. Then ask them to make these instructions more polite. They can use the following expressions:
Could you please ┉ ?
Please do ┉ .
Can you do ┉ ?
Draw a conclusion:
The first way of asking others to do something is called “ORDER” which is not very polite enough. And the second way is called RREQUEST” which is more polite than the first one.
Step 3. Practice

(5) Watch TV plays after you finish your homework.
Step 4. Language focus
Ask one of the students to stand up. And then ask the others answer the question: What did I tell him? Then help the students to say in this way: You told him to stand up.
Conclusion:
Tell somebody to do something
Tell somebody not to do something
Ask somebody to do something
Ask somebody not to do something
The first two are not so polite as the second two. Give the students some more examples:
