    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.

My name is Maisie Hall and I have five brothers and sisters! Life in our house is fun, but it's difficult, too.

On school days I get up very early at 6:30 a.m. I have my breakfast first. After breakfast I take a shower and get dressed.

At 8:00 a.m. we go to school by bus. School starts at 8:30 a.m. and we go home at 3:00 p.m. After school I don't watch TV. I clean the house for my mom and play with my brothers and sisters.

We have dinner together at 7:00 p.m. My baby brother goes to bed at 8:00 p.m. and my other brothers and sisters go to bed at 9:00 p.m. Then I can study!

From 9:00 p.m. to 10:00 p.m. I do my homework and read a book. After that I brush my teeth and go to bed.

Script Murder (剧本杀), also known as the mystery of murder, is gaining popularity among young people. A guest in the party secretly plays the role of the murderer without the knowledge of others while other guests, as players, need to find out the murderer through investigating (调查) and reasoning. In recent years, this game has gradually become a top choice for parties in China. 

There are two ways to play Script Murder, that is, online and offline. Most of the scripts provided by online apps are free; only a few high-quality scripts need to be paid. Players play role-playing games in a network "room" while offline stores usually set up scenes exactly the same as script settings. Players live in a "room", performing stories through language, expression, conversation, body movements and so on. This game often takes about 4 to 6 hours in total. 

In fact, murder-inspired board games, card games and party games have been around at least since the so-called golden age of British crime fiction in the 1920s and 1930s. The enduring popularity of these games presents a mystery of its own: What drives people to spend an evening investigating fake cases and hunting for "murderers"? 

One simple explanation might be curiosity (好奇心). When he's playing Script Murder in particular costumes, one feels like he's in that world. But that is not the full story. Instead, murder games follow a surprisingly complex set of psychological (心理的) rules, which can be educational and help people develop important thinking and acting skills. 

"People are considering the games as a way to simulate threatening plots (模拟威胁情节) and then play around with how they would react to it." Coltan Scrivner, a behavioral scientist, says, "After all, real-life violent (暴力的) crime is every person's worst nightmare."
