First of all, I have ridden my bike to school instead of taking the car for two years. This helps reduce air pollution. Second, I have been used to thinking twice before throwing things away. I recycle paper boxes, plastic bottles, and glass jars. I also avoid using plastic bags when shopping. My family produces less waste now. Protecting the environment is everyone’s responsibility. I will join the school’s environmental club to do more to make the world better. 【亮点解析】 开篇交代时间，用现在完成进行时体现持续性。 “I have been trying to live a green life for the past two years.”用现在完成进行时强调“从两年前开始一直持续到现在”，暗示环保不是一时兴起，而是长期坚持的行为。同时点明了第二个要点“从什么时候开始”。 行动具体可操作，分类清晰。 出行方面：“ridden my bike to school instead of taking the car”——把“不开车”换成了“骑车”，行动明确；废弃物处理方面：“recycle paper boxes, plastic bottles, and glass jars”——三类可回收物逐一列出；“avoid using plastic bags when shopping”——购物场景的具体做法。三个行动覆盖了“行”“废”“购”三个生活场景，读者可以照着做。 效果与行动一一对应，逻辑紧密。 “This helps reduce air pollution.”紧跟在骑自行车之后，直接说明减排效果。“My family produces less waste now.”放在回收利用和少用塑料袋之后，说明家庭垃圾减量的结果。效果不单独成段，而是紧随行动之后，因果关系清晰。 看法简短有力，计划具体可行。 “Protecting the environment is everyone's responsibility.”一句话表明观点，简洁不啰嗦。“I will join the school's environmental club”是具体计划，“to do more to make the world better”补充目的。计划从个人行为延伸到组织参与，体现了环保意识的升级。 五、阶梯训练 （一）句子训练 Level 1 汉译英 1. 环境污染已经成为全球性的严重问题。 ____________________________________________________________ 2. 为了减少垃圾，我们可以少用塑料袋。 ____________________________________________________________ 3. 再利用意味着再次或以另一种方式使用某物。 ____________________________________________________________ 4. 当我们回收时，我们把用过的材料变成新产品。 ____________________________________________________________ 5. 在过去的几年里，人们种了成千上万棵树。 ____________________________________________________________ Level 2 句型仿写（参照例句完成句子） 句型 1：... has become a serious problem.（描述问题严重性） 例句： Environmental pollution has become a serious problem around the world. （1）空气污染在许多城市已经成为严重的问题。 ____________________________________________________________ （2）水污染在发展中国家已经成为严重的问题。 ____________________________________________________________ 句型 2：To reduce ..., we can ...（描述减少污染的方法） 例句： To reduce trash, we can use fewer plastic bags. （1）为了减少水污染，我们可以停止向河流中排放废物。 ____________________________________________________________ （2）为了减少空气污染，我们可以多乘坐公共交通。 ____________________________________________________________ 句型 3：Reusing means ...（解释再利用） 例句： Reusing means making use of something again or in another way. （1）再利用意味着再次使用物品，比如用旧瓶子种花。 ____________________________________________________________ （2）回收意味着把用过的材料变成新产品。 ____________________________________________________________ 句型 4：When we recycle, we turn ... into ...（描述回收过程） 例句： When we recycle, we turn used materials into new products. （1）当我们回收时，我们把旧报纸变成新的纸制品。 ____________________________________________________________ （2）当我们回收时，我们把塑料瓶变成新的塑料制品。 ____________________________________________________________ 句型 5：... have / has ... for ... years.（描述持续行动） 例句： People have planted trees for many years to protect the environment. （1）我们学校进行垃圾分类已经两年了。 ____________________________________________________________ （2）我已经骑自行车上学三年了。 ____________________________________________________________ 句型 6：Small acts can make a big difference.（表达信念） 例句： Small acts can make a big difference to our environment. （1）每个人的小小努力都能带来巨大的变化。 ____________________________________________________________ （2）如果我们齐心协力，就能实现这一目标。 ____________________________________________________________ Level 3 句子升级 要求：参照下方示例，将基础句升级为内容更丰富、表达更高级的句子。 示例： 基础句：Pollution is serious. 升级句：Environmental pollution has become a serious problem around the world. 1. 基础句：We should reduce waste. 升级句：____________________________________________________________ 2. 基础句：We can reuse things. 升级句：____________________________________________________________ 3. 基础句：We can recycle waste. 升级句：____________________________________________________________ 4. 基础句：People have planted many trees. 升级句：____________________________________________________________ 5. 基础句：We should protect the Earth. 升级句：____________________________________________________________ 6. 基础句：The environment is better now. 升级句：____________________________________________________________ （二）篇章训练 如今环境污染问题日益严峻，低碳生活人人有责。请以 “Go Green, Live Low-carbon” 为题，写一篇英语短文。 要点： 1. 目前身边存在的污染问题； 2. 我们日常生活中的低碳做法（节约水电、绿色出行、垃圾分类、多种树等）； 3. 呼吁大家一起保护环境。 要求：80词左右，语句通顺，语法正确。 _________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 参考答案 Level 1 汉译英 1.
