【话题范文必背】
Protect Our Precious Nature
Nature gives us everything we need—fresh air, clean water and delicious food. But now, our nature is in danger because of human activities.
Last month, my hometown experienced a terrible sandstorm. The sky turned yellow, and we had to wear masks when going out. The weather reporter said the sandstorm happened because too many trees were cut down in the nearby desert. Besides, I often see people throw plastic bottles into rivers—these bottles make the water dirty, and fish can’t live in polluted water anymore.
We must take action to save nature right now. First, we can plant more trees to stop deserts from expanding. Second, we should recycle waste like paper and glass instead of throwing them away. Third, we can ask our family and friends to use less plastic, such as bringing their own cups to buy drinks.
Nature is precious, and it’s our duty to protect it. If everyone does a little, our nature will become better and better.
保护我们珍贵的自然
自然给予我们所需的一切——新鲜的空气、干净的水和美味的食物。但现在，由于人类活动，我们的自然正处于危险之中。
上个月，我的家乡遭遇了一场严重的沙尘暴。天空变成了黄色，我们出门时不得不戴口罩。天气预报员说，沙尘暴的发生是因为附近沙漠的树木被砍伐得太多了。此外，我经常看到人们把塑料瓶扔进河里——这些瓶子让水变脏，鱼儿再也无法在被污染的水里生存。
我们必须立即采取行动拯救自然。首先，我们可以种更多的树，阻止沙漠扩张。其次，我们应该回收纸张、玻璃等垃圾，而不是把它们扔掉。第三，我们可以呼吁家人和朋友少用塑料制品，比如自带杯子买饮料。
自然很珍贵，保护它是我们的责任。如果每个人都做一点，我们的自然会变得越来越好。

写作练习
Dear Peter,
Thank you for your letter. It’s important to talk about global warming—it brings many bad effects, like ice melting and more hot days.
People around me are trying to deal with it. My family turns off lights when leaving rooms to save electricity. My classmates and I often take buses to school instead of asking parents to drive us.
I have two suggestions for you. First, you can plant a small tree in your garden—it helps absorb carbon dioxide. Second, use reusable boxes for food instead of disposable ones.
Let’s work together to stop global warming!
Yours,
Li Hua
