Changes in My Hometown — Transportation In the past, the roads were narrow, rough, and made of mud. It was hard to walk or drive, and traveling took a long time. Now, we have wide, smooth roads. Buses run on time, and many families own cars. Travel is fast and convenient. The change happened because the government built new roads and people worked together. How I feel — I feel proud and happy. Life is much easier now. Show your poster and introduce. Changes in My Hometown — Environment In the past, the land was dry and sandy. Sandstorms often covered everything in dust. The hills were bare and lifeless. Now, the land is covered with green trees and flowers. The air is fresh, the water is clear, and birds have returned. The change happened because the government and local people planted millions of trees and never gave up. How I feel — I feel grateful and amazed. Our hometown has become a greener, better place. Show your poster and introduce. Changes in My Hometown — Living Facilities In the past, people lived in small, old houses. There was no hospital nearby. Students studied in poor school buildings. Now, we have new houses, a modern hospital, and a well-equipped school. There are street lights and a community center. The change happened because the government invested in local development and people worked hard together. How I feel — I feel grateful and hopeful. Our life is more comfortable now, and I believe the future will be even brighter. Poster making : Changes in My Hometown. Each group will put up their posters, and the entire class will vote for the "Best Poster". We started today with two pictures of Saihanba—one from 1962 and one from today. Now we know the words to describe this amazing change: sandy → green, sandstorms → clean air, difficult → miracle. Remember: change is possible when we work together and never give up. 05 Summary Summary Unit 1 The Changing World (Section B Vocabulary in use) 06 Language points Let's learn and take notes. narrow /ˈnærəʊ/ adj. 狭窄的 词性转换：副词 narrowly（狭窄地；勉强地），名词 narrowness（狭窄） 反义词：wide（宽阔的） 固定搭配：narrow road（狭窄的道路） 用法：形容词，常用来描述道路、街道等物理空间的狭窄。 词 讲 练 The road used to be narrow and dirty.（这条路过去又窄又脏。） The street is too narrow for two cars to pass.（这条街道太窄，两辆车无法并行。） 例 填空：The old bridge is very _________ (narrow) than the new one. 翻译：以前这条路很窄，现在很宽。 narrower The road used to be narrow, but now it is wide.
