When I was a child, there were only old houses everywhere. The river near our village was dirty, and people threw rubbish into it. Most people went to work on foot or by bike because the roads were narrow and bumpy. Living conditions were hard—many families shared small rooms with no running water. But now, everything is different. Tall buildings stand in the city center, and the river has become clean with clear water. You can even see fish swimming in it! Wide ring roads have replaced the old narrow streets, and buses and cars are common for transportation. People now live in comfortable apartments with modern facilities like air conditioners and elevators. I am so glad to see these changes. We will work hard to make our hometown even better. 范文二 The Changes in My Hometown Great changes have taken place in my hometown. In the past, people lived a poor life. The houses were small and dark. The roads were narrow and there were not many ring roads. Few children had the chance to receive education Now our living conditions have improved a lot. People are living in tall and bright buildings. What's more, more and more ring roads appear. There are many modern schools and the children can learn lessons on the Internet. I hope my hometown will be more and more beautiful in the future and people will live a better life.

There are many kinds of pollution around us, such as air pollution, noise pollution, water pollution and light pollution. We can find that pollution not only damages our environment but also harms people's health. So we should not throw rubbish everywhere. Some factories pour waste water into the rivers and the lakes. The behavior of these factories will pollute the water. So we should stop factories from pouring waste water directly into rivers. We have only one earth. We must keep our environment clean and tidy. We must try our best to protect her,and make our home more beautiful. 学科网（北京）股份有限公1 / 1 学科网（北京）股份有限公司 $ 专题01 Units 1~2 重点单词短语句型&写作通用表达 Unit 1 The Changing World 重点单词 学科网（北京）股份有限公1 / 1 学科网（北京）股份有限公司 1. volunte er /vɒlənˈtɪə/ n. 志愿者 2. be ll /bel/ n. 钟（铃）声，铃，钟 3.

When I was a child, there were only old houses everywhere. The river near our village was dirty, and people threw rubbish into it. Most people went to work on foot or by bike because the roads were narrow and bumpy. Living conditions were hard—many families shared small rooms with no running water. But now, everything is different. Tall buildings stand in the city center, and the river has become clean with clear water. You can even see fish swimming in it! Wide ring roads have replaced the old narrow streets, and buses and cars are common for transportation. People now live in comfortable apartments with modern facilities like air conditioners and elevators. I am so glad to see these changes. We will work hard to make our hometown even better. 范文二 The Changes in My Hometown Great changes have taken place in my hometown. In the past, people lived a poor life. The houses were small and dark. The roads were narrow and there were not many ring roads. Few children had the chance to receive education Now our living conditions have improved a lot. People are living in tall and bright buildings. What's more, more and more ring roads appear. There are many modern schools and the children can learn lessons on the Internet. I hope my hometown will be more and more beautiful in the future and people will live a better life.

Pollution, deforestation, and waste are harming our planet. For example, many rivers are polluted by chemical factories, and animals are losing their homes because of deforestation. We can do something to help. First, we should use cloth bags instead of plastic bags when shopping. Second, we can recycle paper and bottles to reduce waste. Third, we must plant more trees to keep the air clean. Finally, we should tell our friends and family to join us in protecting the environment. Protecting the earth is our duty. Let’s act now before it’s too late! 范文二 Saving the Earth How to protect the environment has become one of the biggest problems in the world. There are many kinds of pollution around us, such as air pollution, noise pollution, water pollution and light pollution. We can find that pollution not only damages our environment but also harms people's health. So we should not throw rubbish everywhere. Some factories pour waste water into the rivers and the lakes. The behavior of these factories will pollute the water. So we should stop factories from pouring waste water directly into rivers. We have only one earth. We must keep our environment clean and tidy. We must try our best to protect her,and make our home more beautiful. 学科网（北京）股份有限公1 / 1 学科网（北京）股份有限公司 $
