T: Can you find the answer? In which paragraph ? S:„
T:For more details, let’s move on to Intensive reading. Paragraph One, first. What was Mao Zedong’s dream? Ok. Let’s say the answer together. This sentence comes from Mao Zedong’s poem. This is the poem. Can you find the Chinese meaning of the sentence? S:„

T: what does hold back refer to？Continue or stop? S:„
T: what does clouds and rain refer to？Flooding or electricity? S:„
T: Well done! So we can answer this question in another way. That is to build a dam across the Yangtze River to control flooding and harness its power. Do you think so?

Who’d like to answer the first question? What is the size of the Dam? S:„
T: Good. But how tall is the dam? It’s about 185 meters. Here is the question. This place is very high, but this place is very low. How does a ship get through the dam? Can you give me a solution? This is the first highlight of the Three Gorges Dam. Let’s watch

T: Did you see the photo about Wuhan last year? Wuhan was flooded. Someone on the Internet said that the Three Gorges Dam was useless, because it couldn’t control flooding. What’s your opinion? Since we have the dam, why was Wuhan flooded last year? S:„
