Lesson 46 Protect our environment
第46课：保护我们的环境
预习导航+阅读训练
原文翻译
我叫凯蒂。
我认为每个人都应该爱护环境。我住在埃德蒙顿，它是加拿大的一座城市。埃德蒙顿的空气和水很干净，但有时人们浪费严重。
我们浪费最多的是什么呢？我觉得是纸张。人们也浪费水。我不想浪费水，我尝试用很多方式来节约用水。我快速淋浴（洗短时间的澡）。我经常检查以确保没有任何漏水情况，而且我从不忘记关水龙头。
我们在家进行回收利用吗？是的！我们对汽水罐、啤酒瓶和废纸进行分类。每周都有一辆卡车来收取我们的回收物。它们会被制成新的东西。我们也重复使用塑料袋。我们反复使用它们，或者用它们装其他垃圾。
汽车和工厂造成的污染最多。我认为埃德蒙顿的汽车太多了。更多的人应该骑自行车或者乘坐公共汽车。我每天骑自行车去上学。与其他交通方式不同，自行车不会产生任何污染。公共汽车会产生一些污染，但很多人可以乘坐一辆公共汽车出行。公共汽车产生的污染比汽车少。
事实上，如果我们每个人在生活中做出一个小小的改变，我们就能对我们的环境产生很大的影响。保护环境并不太难。我们只需要努力尝试。
我们喜欢骑自行车。这对环境有好处。
以下是文中重要语法的提取：
一、情态动词 should 的用法
表示建议或义务，后接动词原形。
例句：Everybody should take care of the environment.（每个人都应该爱护环境。）
作用：强调环保行为的必要性。
二、一般现在时的用法
1. 表示习惯性动作或事实：
例句：I ride my bike to school every day.（我每天骑自行车上学。）
结构：主语 + 动词原形/第三人称单数形式。
2. 描述客观事实或现状：
例句：The air and water are clean in Edmonton.（埃德蒙顿的空气和水很干净。）
三、比较级的用法
用于两者对比，结构为“形容词比较级 + than”。
例句：Buses make less pollution than cars.（公交车比汽车产生的污染更少。）
注意：“less”是“little”的比较级，修饰不可数名词“pollution”。
四、被动语态的用法
结构：be + 过去分词，表示动作的承受者。
例句：Recycling is made into new things.（回收物被制成新东西。）
作用：强调动作的对象（回收物）而非执行者。
五、条件状语从句（if 引导）
结构：if + 一般现在时从句，主句用情态动词或一般将来时。
例句：If each of us makes a small change, we can make a big difference.（如果我们每个人做出一点改变，就能带来大影响。）
六、否定句与否定词的使用
通过“don’t/doesn’t”或“never”构成否定。
例句：I never forget to turn off the tap.（我从不忘记关水龙头。）

Let's Save Our Planet
In a small town called Greenville, people are thinking about how to protect the environment.
Alex, a middle - school student, says that people here use too many plastic bags when shopping. These plastic bags are thrown away everywhere and make the town look messy. Alex always uses a cloth bag to carry things. He also tells his friends to do the same.
There is a big river near Greenville. But now it's not as clean as before. Some factories pour waste water into it. Lisa, who loves fishing in the river, is very sad about this. She writes letters to the local government, asking them to stop the factories from polluting the river.
Many people in Greenville like to drive to work. This makes a lot of air pollution. Tom, a bike shop owner, suggests that people should ride bikes more often. He says riding bikes not only helps keep the air clean but also makes people healthier.
If everyone in Greenville starts to make small changes, like using cloth bags, protecting the river, and riding bikes, the town will become a better place to live in.
