Unit 1 The Changing World! Section B 1a-1f 1 By the end of this lesson, we will be able to： 1. make predictions through the title and the picture. 2. understand the positive impact of infrastructure development (like the railway) on local lives. 3. develop awareness of global changes and the importance of international collaboration. 1a Does your hometown have a train system? How does it benefit local lives? Yes. People can travel by train, and people from other cities can also come to our hometown for a trip by train. It saves time. Brainstorming Prediction 1b Look at the title and the picture. What is the text probably about? Title: On the Fast Track From the title “On the Fast Track” and the picture of a train, I think the text is probaly about a new railway line. The text may talk about how this railway makes travel faster, and what good changes it brings to local people’s lives. 通过预测任务引发学生思考，培养学生利用标题和图片线索进行推断预测的能力 On the Fast Track In 2017, the new 480-kilometre Mombasa-Nairobi railway was opened. Before then, the only transport links between Mombasa, Kenya’s main port, and Nairobi, Kenya’s capital, were rough roads and an old railway line completed in 1901. The old trains were very slow. It took 10 hours to get to Nairobi from Mombasa by train. However, the new railway, built with China’s help, has already cut the travel time between Mombasa and Nairobi to about five to six hours for passengers. Now, more than two million people use it every year. Local Kenyans have benefited a lot from the new railway. A government worker said, “I’m very happy with the new railway built by our Chinese friends. Many changes have taken place in the town over the last few years, and the people who live here have become rich.” A businessman said, “My experience of using the train since 2017 has been good. It is very convenient and doesn’t cost much money. I am able to get to places on time and make business deals with ease.” The railway has also made the transport of food easier. “It used to take hundreds of lorries to carry food between the two cities, but now it takes only two or three trains,” said a supermarket manager. As a result, people now have more fresh food to eat. Although China and Kenya are far away from each other, the railway shows how different countries can work together to build a better world. 交通路线 崎岖的 受益 政府 发生 便利的 花费 按时 结果 交易 1c Match the numbers with the information. 1. ____________: the year the new railway was opened 2. ____________: the year the old railway line was completed 3. ____________: the number of people who use the new train every year 4. ____________: the length of the Mombasa-Nairobi railway in kilometres 5. ____________: the hours it used to take to reach Nairobi from Mombasa by train 6. ____________: the hours it takes to reach Nairobi from Mombasa now by train about five to six 10 480 1901 2017 over two million about five to six over two million 2017 1901 10 480 通过数字信息匹配，训练学生快速定位文本细节信息的能力，聚焦文本中的关键数据 1d Read again and answer the questions.
