StepⅠ Revision
Check the homework.
Ask the students to act out the play.
T: Yesterday I asked you to prepare for the play-acting. Have you prepared? Now I want to ask three students to have a try.
After they finish, make some comments on their performances.
Step Ⅱ Word study
Ask the students to finish Exx. 1 and 2 in Learning about Language.
Then check the answers with the class.
Step Ⅲ Grammar
First ask the students to find out the examples of the past participle as the adverbial in the play:
Sample sentences:
1. An expert in phonetics, convinced that the quality of a person’s English decides his/her position in society. P28
2. But, sir, (proudly) once educated to speak properly, that girl could pass herself off in three months as a duchess at an ambassador’s garden party. P30
Explanation:
T: The past participle as the adverbial is a very important grammar, and it can indicate time, condition, reason, and way. We can add when / while / if or other conjunctions before the past participle in order to make the meaning more clearly. For example:
Show the following.
If bitten by a snake, you should send for help and don’t walk.
The room, although supposed to be kept locked, was often left open.
T: Now please look at the following examples. Can you rewrite these sentences?
Show the following.
1. Given more time, we could do it better.
2. Heated to a high temperature, water will change to vapour.
3. Frightened by the noise in the night, the girl did not dare sleep in her room.
4. Disturbed by the noise, we had to finish the meeting early.
5. Seen from the hill, the park looks very beautiful.
6. She walked out of the house, followed by her little daughter.
Sample answers:
1. When / If we were given more time, we could do it better.
2. When / If it is heated to a high temperature, water will change to vapour.
3. As she was frightened by the noise in the night, the girl did not dare sleep in her room.
4. As we were disturbed by the noise, we had to finish the meeting early.
5. When it is seen from the hill, the park looks very beautiful.
