Careful reading Read Part.1 and answer the questions. 1 How long did it take to travel from Mombasa to Nairobi by the old train before 2017? It took 10 hours. 2 What were the only transport links between Mombasa and Nairobi before the new railway was opened in 2017? The only transport links were rough roads and an old railway line built in 1901. Read Part.2 and fill in the chart. However, the new railway, built with China's help, has already cut the travel time between Mombasa and Nairobi to about four 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 fewyears, and the people who live here have become rich."A businessman said, "My experience of using the train since 2017 has been good.

Person What they said or benefited from the new railway A government worker A businessman A supermarket manager 1. Happy with the new railway built by Chinese friends. 2.

What type of writing is the text? 2. What was the problem with the old railway? 3. How have local Kenyans benefited from the new railway? It is a news report / informational text (or narrative non-fiction). It reports facts about the Mombasa–Nairobi railway and includes quotes from local people. The old railway was built in 1901 and was very slow. It took 10 hours to travel from Mombasa to Nairobi by train. The only other transport links were rough roads. A government worker said people in the town have become rich and many changes have taken place. A businessman said the train is convenient, cheap, and helps him get to places on time to make business deals with ease. A supermarket manager said food transport is easier: food used to need hundreds of lorries, but now only two or three trains carry it, so people have more fresh food to eat. 4. Why is it important to make food transport easier? 5. What does “on the fast track” mean? Because easier food transport means food can be moved more quickly and in larger quantities. This gives people more fresh food to eat (as the supermarket manager said). It also reduces the need for many lorries, which may be slower and less efficient. This exact phrase does not appear in the passage. However, based on the context of the new railway cutting travel time from 10 hours to 4 hours, “on the fast track” would mean making rapid progress or moving quickly toward a goal (e.g., development, economic growth, or better transport). 1e Complete the table with the information from the text. Paragraph 1 Introduction old railway Paragraph 2 new railway Paragraph 3 comments from locals government worker: businessman: supermarket worker: Paragraph 4 conclusion Before 2017: only rough roads and old railway (1901). Old trains very slow → 10 hours. Built in 1901, very slow, 10 hours. Opened in 2017, 480 km, built with China’s help. Travel time: 4 hours. Over 2 million users/year. Happy, many changes, people become rich. Convenient, cheap, on time, easy business deals. Food: hundreds of lorries → 2-3 trains. More fresh food. China & Kenya far apart, but railway shows countries can work together for a better world. 1f Discuss the questions. 1. Have you seen or heard of any similar changes in the world over the last several years? Where was it and what happened? Yes, I have heard of similar changes. For example, in Pakistan, the China-Pakistan Economic Corridor (CPEC) has built new roads, railways, and power plants over the last several years. Before CPEC, some areas had poor transport and frequent power cuts. Now, travel times between major cities like Islamabad and Lahore have been greatly reduced, and many people have jobs in construction and transport. This has helped local businesses grow and improved daily life, just like the Mombasa-Nairobi railway in Kenya. 2. In what other ways can China work together with other countries to build a better world? China can work with other countries in several other ways to build a better world: Green energy projects – Help build solar or wind farms in countries that need clean and affordable electricity. Healthcare cooperation – Send medical teams, build hospitals, or share vaccines to fight diseases together. Education and training – Offer scholarships and vocational training to help young people learn useful skills. Digital connectivity – Help build internet networks and smart city technologies so more people can access information and online services. Disaster relief – Work together to provide food, water, and shelter quickly when earthquakes, floods, or other disasters happen. greenhouse, Activity 2 compound word 2a Use a word on the left and a word on the right to create a compound word.
