If your pencil box is broken, the batteries(电池)in your flashlights run out, or you have some leftover food, how will you deal with these things? You will probably throw them all into one rubbish bin. But actually, we need to sort(分类)all the rubbish separately. If you don't sort your rubbish, all of it will go to a special place where it is buried(埋藏)together. As a result, it willtake upsome fields. Some rubbish will pollute the groundwater. Some rubbish that can be reused will be wasted.
In recent years, some Chinese cities have been working hard on rubbish sorting.
Shanghai has called on all the people living in this city to sort their rubbish into four groups: wet, recyclable, harmful and dry. Wet waste is known as household waste. They are things you don't want but pigs can eat. Paper, metal, glass, plastic and other things that can be reused are recyclable waste. Harmful waste includes thins like medicine, batteries. Finally, any waste that is not wet, recyclable or harmful will go to the “dry waste” bin.
Many other Chinese cities are also using this way to sort their rubbish. For example, Deyang has been sorting its rubbish into the same four groups since several years ago. Students in Deyang have already received waste-sorting guidebooks. They have studied these books and known how to sort the rubbish.
China is now improving its waste-sorting efforts. There is still a long way to go. But it's never too late to learn how to sort your rubbish rightly. We should take an active part in it.
