S: The passage is about the development and influence of Zheng He’s achievement.
T: History develops in two ways, and different choices may result in different outcomes. Discuss with your partner and find out what are the two different outcomes. Then please raise some questions following the examples below.
Students discuss and think out different outcomes.
1. What if China was the first to discover Australia?
2. What if Chinese first settled in Australia and America before the westerners?
3. What if Chinese continued trade with the western world in a large scale after Zheng
He’s expedition?
4. What if Chinese began to run restaurants in Europe in 1800s?
5. What if in most part of the world people can speak Chinese?
6. What if Chinese set up Chinese clinics in Europe after Zheng He’s exploration?
Task two: Discuss and explore
T: Look at the second topic and find out more possibilities.
Students read the requirement and find more possibilities following the sample.
Possible answers:
1. If China had continued to sail further down the African coast, China might have discovered the way to the west Europe. Through continuous contact with the west, China could have established embassy relationship with the westerner.
2. If China had continued to explore to the south and across the Pacific Ocean, she might be the first to discover Australia and America. This way, Chinese might be the dominant language around the world.
3. If China had opened her door earlier as in 1400s, she might have suffered greater loss and have been invaded by the westerners earlier.
