This sentence comes from Mao Zedong’s poem. This is the poem. Can you find the Chinese meaning of the sentence? 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?
But what is the dam like? Let’s move on to the second paragraph. Please read Paragraph 2 and answer the questions.
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:„
T: Because of the continuous heavy rainfall in Wuhan, not the upper or middle stream. Are you clear?
T: How does the Three Gorges Dam generate electricity? S:By the pressure of water.
T:Have your noticed the direction of the water? Usually, the water flows downward, just like this. But here it flows upward. The upward water is the second highlight of the Three Gorges Dam. But why does the water flow upward? Let’s watch the second video and find the answer.
Have you got the answer? Who can explain it for us? S:„
T: Are you clear now? What do you think of the two highlights? S: „
T: Next time when you visit the Three Gorges Dam, remember to see them by yourself. Does the dam have other advantages? Or does it have disadvantages? Let’s move on to the last three paragraph. Group work. Complete the table according to the information you have found from the passage and the reading material. You can omit the repeated aspects. I’d like to divide you into two big groups. The students on the left should find the advantages, and the others find the disadvantages. Let’s have a competition to check which group is more quickly. Here are the tips. Let’s begin.
