之前，我和妈妈去楼下扔垃圾，我发现其他人都把垃圾扔在垃圾桶旁边，堆都堆不下了，只有老奶奶一个人收拾。于是，我们决定帮老奶妈一起捡。可是，其它人要是明天，后天……都扔在旁边怎么办呢？
Previously, my mother and I went downstairs to throw garbage, and I found that everyone else was throwing garbage next to the trash can, and the pile couldn't fit any more. Only the old lady was cleaning up. So we decided to help the old nanny pick it up together. But what if everyone else leaves it by tomorrow, the day after tomorrow?
回到家，我还在发愁时，妈妈高兴地跑过来对我说：“你看，现在垃圾桶可以主动开门了！”
When I got home and was still worried, my mother happily ran over to me and said, "Look, now the trash can can can open the door voluntarily
我急忙跑下去看，果然，那里的地上没有了垃圾，所有人都能自觉地把垃圾扔到垃圾桶里了。
I hurriedly ran down to take a look, and sure enough, there was no more garbage on the ground there. Everyone could consciously throw their garbage into the trash can.
只需要用手机扫一下二维码或在手机上录一个脸，然后到那儿一扫垃圾桶就能自动打开了，真是太方便了。
Just scan the QR code with your phone or record a face on your phone, then scan the trash can there and it will automatically open. It's really convenient.
那个软件上还能积分，一些积分就能换一个实用的东西，哪个人不想要呢？
That software can also earn points, and some points can be exchanged for something practical. Who wouldn't want it?
就是这个软件，它让人们可以自觉垃圾分类，真是太棒了！垃圾分类，从我做起！
It's this software that allows people to consciously sort their garbage. It's really great! Garbage classification starts with me!
