Unit 2 The environment 同步练习(一)总分 100分 时间 40 分钟 成绩评定 __________________ I. 学生习作欣赏：ASave our earthWith the development of society, the earth is being damaged by people who are seeking comfort at all costs. The sky is no longer blue. The air is no longer fresh. The rivers are no longer clean. Many animals and plants are disappearing from the earth. And the size of deserts is growing rapidly every year. Our planet has been seriously polluted.There are many reasons for this. First, many paper mills send out waste water and smoke that are not processed. Second, the expansion of large cities also brings about terrible pollution. Nowadays, waste gas and everyday rubbish have become big problems. Third, a huge number of trees are cut down each year. Whenever there is a strong wind, the top soil is blown away. Sandstorms badly affect people’ s lives and health.We all know that we have only one home. If we continue polluting it, the earth will turn out to be a planet which is unfit for us to live on. To save the earth means to save ourselves. Let’s take action without any delay. Let’s try our best to save the earth, our home.II. 阅读下文，完成后面问题：Wuzhen (乌镇), an ancient river townOn both sides of a stone-paved street stand pubs, restaurants, pawnshops(当铺), and other businesses all housed in brown wooden buildings.
