先听一遍
听一听，一个塑料瓶回收后可能变成什么。
展开英文短文，再悬停查词
I used to think a plastic bottle had only one life. You drink from it, throw it away, and it is gone.
At a recycling center, I learned that bottles can become new bottles, clothes, or other products. But this does not happen by magic.
The bottle must be collected, sorted, cleaned, and changed into material again.
Recycling is useful, but using fewer bottles is even better. The best waste is the waste we do not make.

读懂了什么？
读完后，试着用一句话说出本文的主要意思，并从原文找出支持它的一句话。
查看中文译文
以前，我以为塑料瓶只用一次：喝完饮料，扔掉瓶子，它就没有下文了。
在回收中心，我知道了瓶子可以变成新瓶子、衣服或其他产品。但这个变化不是凭空发生的。
旧瓶子要经过收集、分类、清洗，再加工成材料。
回收有用，少用塑料瓶则更好。最理想的废弃物，是我们一开始就没有制造出来的。
