Now let’s see how Li Rui’s hometown has changed. Watch and answer. 1a The photos show changes in Li Rui’s hometown over the years. What are they? How do they make you feel? The land was dry and poor. Now it’s green with plants, a river, and a village. Hopeful and happy — nature and life can return with hard work. I’m going to call Li Rui and give him a surprise. Why does George call Li Rui? 1b Listen to a telephone conversation. Then answer the questions. Because he and his father are going to visit Li Rui’s hometown, and he wants her to be their guide. They are good friends. About 20 years ago. 2. What is the relationship between George’s father and Li Rui’s grandfather? 3. When did George’s father last visit the place? Thank you so much, Li Rui. Take us to these places. The transportation is so convenient now. It doesn’t matter. We are very happy that you could come. My grandfather also misses you very much. There are so many shops. The mountains are truly green! 1c Li Rui is now showing George and his father around her hometown. Listen to their conversation and complete the table.

How do you think they happened? Past Present It took half a day to reach the town. Going to school by bus took 40 minutes over rough roads. With the new roads, it takes only an hour. Going to school takes only 15 minutes. They used to travel far to see a doctor. The town has built a new hospital. They didn’t have any good places for shopping. They now have a supermarket down the street. The hills were covered with sand. They are now covered with beautiful trees. 角度一：政府支持（侧重政策） I think the changes happened because the government provided support. They built new roads, a hospital, and helped with planting trees. With better infrastructure, people's lives improved a lot. 角度二：当地人努力（侧重人力） I believe the local people worked really hard. They planted trees on the hills and built new buildings step by step. Without their hard work, nothing would change. 角度三：科技发展（侧重技术） Maybe new technology played a big role. Better machines helped build roads faster, and scientific farming made the land greener. Technology made these changes possible. 角度四：时间积累（侧重过程） I think changes like this take a long time. It didn’t happen in one day—people kept working for years. Little by little, the town became better and better. 角度五：多因素结合（综合角度） I think it was a mix of all these: the government gave support, people worked hard, and technology helped. Together, they turned a poor town into a much better place to live. The government led us to overcome many difficulties together. 2a Rank the following problems from 1 to 4, with 1 being the worst. Give your reasons. farmland shortage sandstorms difficult environment lack of technology n. /ˈsændstɔːm/  n. / ˈfɑːmlænd/  n. /ˈʃɔːtɪdʒ/ n. /læk/ farmland shortage – No land, no food. sandstorms – Harm health and crops. lack of technology – Slows down development. difficult environment – Can be improved with effort. This place is really different from when I was here before. I also heard many stories about the past from my grandfather. We’re almost home. My grandpa is waiting for you at home. Welcome back here, my friend! My old friend, I miss this place very much. The changes here have really surprised me 2b Listen to the conversation between George’s father and Li Rui’s grandfather. What problems in 2a did they mention? They mentioned sandstorms and farmland shortage.
