But I still remember what it was exactly like. And I often “see” it in many of my dreams. My hometown was a beautiful place. It stood beside a wide river and was rich in fish and rice. But in the old days it was a poor little town. Many people had no work. They lived a hard life. There were no tall buildings and the only street was narrow. But trees and flowers made the town beautiful. Just outside the town,there was a river. You could see different kinds of fish swimming in the clear water. People here lived a simple life. Since the government carried out a new policy,great changes have taken place. The streets have been widened. Factories,schools,hospitals,cinemas and theatres have been built one after another. People’s life is greatly improved. You can see tall buildings,big department stores and factories everywhere. Different kinds of cars and buses are running in the wide streets. But with the development of the industry,we have fewer trees. Air pollution and water pollution are becoming more serious. And there are also other problems. We should try our best to make our town richer,but at the same time we must do something to stop pollution. 6.When did the writer leave his hometown?（不超过5个词） _________________________________________________________________ 7.What are the bad results of the development of the industry?（不超过15个词） _________________________________________________________________ 8.What will be talked about at the end of the text?（不超过10个词） _________________________________________________________________ >词汇积累 policy /ˈpɒləsi/n. ______ 参考答案 🟢语法精讲 Ⅰ.用括号内所给单词的适当形式填空 1. chosen 2. succeeded 3. were 4. have been 5. have visited Ⅱ.根据汉语意思完成句子 6. has built 7. been away from 8. led to 9. argued with 10. threw;away Ⅲ.单项填空 11.A 12.C 13.B 14.C 🔵课时精练 Ⅰ.单词拼写 1. digital 2. dirt 3. wide 4. audio 5. track Ⅱ.阅读理解 6.
