Discussion
If you had a time machine, which dynasty would you go back to Why
Which historical figure would you like to meet What would you say to him/her
If I had a time machine, I would like to go back to the Ming Dynasty, when Zheng He, one of the greatest explorers, set sail to explore the western seas.
I would like to meet Zheng He, because he led the navigation for 7 times, strengthening harmonious relations with foreign countries, exposing foreign people to Chinese culture and allowing Chinese to better understand overseas lands. I’d like to ask him: “Why are you so brave to take the risk ” “What was the difficulty in your navigation and how did you overcome it ”
Now, let’s come to today’s lesson—— get closer to two famous explorers.
What difficulties did explorers face in the past
loss of direction
pirate(海盗)
natural disasters
extreme weather
sickness and medical treatment
fear of the unknown
