The "Zero Waste" Challenge
What is a "Zero Waste" challenge? It means making very little waste. What should we do?
Step 1: Reduce (The best way!)
Don't buy things you don't need. Say "NO" to single-use(一次性的) things. Save water and use less electricity.
Step 2: Reuse (Be smart!)
Think before you throw things away: Can I use them again? You can use old jars to keep small things. You can also use old bottles to grow plants.
Step 3: Recycle (The last step!)
If you can't use things again, recycle them. Put old newspapers and boxes into the recycling bin.
Would you like to join us?

2) 文中Step1明确要求我们对一次性物品说"NO"，而不是更多使用一次性物品，该表述错误。

本题是结合本单元环保主题的开放性写作题，第一空填写自己的姓名即可，后续三个空分别对应减少浪费、重复利用物品、资源回收三类环保行为，使用六年级已学的简单英语表达，内容符合零浪费的环保主题就合理，答案不唯一。
