15. Part IV Post-Reading

16. Requirements Task 1: Let’s read the article (p19).
One student reads the king and one reads the wise old man.
Others read the voice-over(旁白).
Loud and emotional.

17. Group work: Think and discuss the following question.
The king faced a very difficult problem. If you were the adviser(谋士) to the king, how can you help him solve the problem?
2 to the power of 63

18. How can you help the king solve the problem?
Solution 1: send the old man to prison and forget about the game
Solution 2: ask the old man to count the rice himself
How can you help the king solve the problem?
Solution 3: ask the old man to think of another prize(official position, house…)
Who can help the king? If I were the adviser of the king, I would give the old man as much as rice as I have, but the old man had to count the rice himself. As we know, that will be a big number. It’s impossible for the old man to finish this task. I think this is a good idea.
Solution 4:
give the old man a piece of land and ask him to grow rice himself

19. Homework Retell the article The king and the rice.
Write an ending to the story to make it acceptable and reasonable.
