   Have you noticed the waste bins(垃圾桶) in different colors on the street? Do you often put all the waste in the same bin? It's reported by Changchun Daily that people must do waste sorting(分类)in most places in Changchun at the end of 2019. Waste sorting is a wonderful way to make good use of energy and protect the environment. But do you know how to sort the waste?

Usually, people should sort their waste into four groups: wet, recyclable, harmful and dry.Different kinds of waste should go into different bins. Wet waste means the things you don't want but pigs can eat, mostly coming from your kitchen. Things that can be used again, such as paper, metal and glass, are recyclable waste. Harmful waste might be dangerous or cause serious pollution, like medicine and batteries(电池). And any waste that's not wet, recyclable or harmful will go into the dry waste bin.

Different countries are trying different methods to sort the waste. A university in England has invented a smart bin. When people drop their waste into the bin. It can tell what kind of waste it it and sort it correctly. The bin can also compress the waste to make it smaller in size and take up less space. In South Korea, people have to separate their food waste from other kinds of waste and pay for it. The more food waste they throw away, the more they pay. Japan has the strictest rules for waste sorting in the world. For example, plastic bottles and their caps should go into different bins.

   There are many kinds of music in the world, such as pop music, country music, rock music and so on. But have you heard of grime? It's OK to say no because it's less than 20 years since this kind of music was invented in the UK.

Hip-hop and grime are both noisy. They reflect the thoughts of young people. But if you know nothing about underground music culture, it's difficult to tell the differences between them. For example, grime singers sing with strong accents(口音) , giving a special feeling to their songs.

Leshurr, known as the "Grime Queen", said that she once tried to hide her accent, for she didn't want people to know where she was from. But one day, she realized she didn't need to change herself just to satisfy other people. There is no doubt that this is the spirit of grime: always by yourself.

There is one more difference between hip-hop and grime. Hip-hop is mainly about being rich and famous while grime singers pay more attention to social problems like wars and illnesses.  

Nowadays, grime has begun to show people its strange beauty. Although grime is only popular with some young people, one thing is for sure: in grime, singers always stay true to themselves.

   “Every worker coming to Beijing has their own reasons. No one lives here without a dream,” said Chen Jianguo, a 35-year-old food deliveryman(送餐员) from a small city called Songyuan.

Chen Jianguo dreamed of having his own business in Beijing about 16 years ago when he graduated from senior high school. but his father asked him to take his place as a truck driver at the oil field. Although Chen disliked the job, he didn’t want to let his father down. He took the job as a truck driver. Then he got married and had a son.

"I got quite good pay, but life was boring there during those years. Most of the time I had nothing to do, because the trucks were not often used," said Chen.

Two months ago, Chen decided to give up his job and come to Beijing. His wife agreed that he should go for his dream.

Chen has been a food deliveryman for a month. He works 15 hours every day and hardly has time for lunch at noon. Chen spends only 10 yuan on each meal to cut the cost of living in Beijing. "I want to give a better life to my wife and little son." he said. "I must work harder and try to become the best food deliveryman at my station." Chen likes his job because he can meet many different people. Every "thank you" from a customer is like praise for his work.
