If you live in Shanghai， you might have taken a "lesson" on garbage sorting（垃圾分类），Shanghai is the first city to carry out（实施）strict rules on garbage sorting． People in Shanghai know that garbage is sorted into four categories（类别）﹣recyclable， harmful， dry and wet waste． If people fail to sort their garbage properly， they can be finedup to 200yuan， while companies will have to pay between 1，000 to 50，000yuan for breaking the rules． Since the rules took effect， the amount of total daily waste in Shanghai has been reduced． The city also rebuilt 21，000 waste﹣sorting stations and more than 40，000 waste bins have been updated．

However， there have also been some problems．Some people complained that it is difficult to deal with wet garbage， as they are asked to remove wet garbage from its bag when dumping． According to the sorting rules， the wet garbage must go in the wet waste bin and the bag must go in the dry waste bin．Because the wet garbage will decompose（分解）properly ad become useful organic（有机的）waste．

By the end of 2020， garbage﹣sorting systems will be set up in 46 cities in our country． Everyone should take an active part in garbage sorting．
