Learning objectives
、
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.

Today our topic is “My Hometown over the Years”. Some students will share something about their hometowns.
Years ago, my hometown was small and quiet. There were no tall buildings, just small farmhouses on the farmland. The main road was a narrow dirt road, not a smooth highway. Near the village, a wooden footbridge crossed the small river. Villagers sold food at a small market on weekends. Sometimes, sandstorms came from the nearby sandy land. Kids played in the schoolyard after class.

塞罕坝
、
塞罕坝位于河北省承德市围场满族蒙古族自治县北部 ，历史上是水草丰沛的皇家猎苑木兰围场，清朝康熙、乾隆、嘉庆三位皇帝曾在此举行木兰秋狝105次，后因过度砍伐退化为荒漠沙地。
1962年塞罕坝机械林场正式组建，369名来自全国18个省区市的创业者上坝造林，经过几代人60多年艰苦奋斗，建成世界上面积最大的人工林生态系统。如今森林面积达115.1万亩，森林覆盖率82%，每年涵养水源2.84亿立方米，固定二氧化碳86.03万吨，成为守卫京津生态安全的绿色屏障。被誉为“河的源头、云的故乡、花的世界、林的海洋”。 2007年5月，塞罕坝自然保护通过国务院审定被批准为国家级自然保护区。 2017年12月5日，联合国环境规划署宣布，中国塞罕坝林场建设者获得2017年联合国环保最高荣誉——“地球卫士奖”。
