　　The Significance of Waste Sorting
　　People are producing waste every day, which is a huge burden on the planet’s habitat. Some waste is not①degradablenaturally, which will exist forever, but some waste can be recycLED and reused again.
　　Waste sorting can help divide the reusable waste from the rest. And three are two reasons for doing this.②Firstly, the earth is limited in its natural resources, and many products are made from③finite resources, which cannot be generated by nature in a short period of time. Simply dumping this kind of products is wasting resources.④Secondly, some part of the waste is of value. To reuse and recycle this kind of waste is to save resources⑤to a large extent, which also contributes to environmental protection.
　　Sorting waste is a meaningful deed. If everyone can do it，small things can make a big positive imPACt on the environment.

　　③指出应该进行垃圾分类的原因，分别用“Firstly”和“Secondly”引导。
