【推荐1】Mr Guo is a teacher from Xi’an. He asked his students to hand in their homework through a QR code (二维码). “We spent an hour or two in class learning how to generate (使产生) the codes, and in the end everything gets easier,” said Guo. “When students finish the homework, they keep it on WeChat. Then, each student makes his own QR code and gives it to me. So I can check their work everywhere using my computer or telephone.”

Students can send the QR codes to Mr Guo by email, QQ and WeChat. When Guo scans (扫描) his students’ QR codes, their homework appears (出现) on his phone. He finds that their homework becomes more creative (创造性的), with many pictures, music and even videos.

Guo’s students like the new way and think it is interesting. “We are living in the information age. Many students like to work with computers, which makes learning more fun.” said Tingting, a student of Guo’s.

“The paper is not easy to keep, but the code is easy to keep and share.” Guo said. “It is worth trying to use new technology in education. Education itself is a kind of creation. I don’t want my students to fall behind the times.”

However, some parents are worried. They are afraid that their children will spend too much time on computers and less time communicating with teachers. But in fact, it’s unnecessary. Students still need to look up information in books and write it down when they do their homework. They only use the code when they hand in their work, which doesn’t take them too much time. Also for teachers, it makes them check the students’ work at any time. And it’s also an easy way to share homework with other students.

【推荐3】This year, COVID-19 broke out again in many places in China. Shanghai is one of the worst cities among them. To fight against COVID-19, Shanghai built many makeshift（临时的）hospitals in the city.

【推荐2】When your pen is broken, or you have some leftover food, what do you do with these things? You will probably throw them all into one bin. But in fact, all of the garbage needs to be sorted separately.

Garbage sorting is a big problem worldwide. In recent years, some Chinese cities have been working hard on it. Shanghai has worked with Alipay to create a service for garbage sorting. People may get points by correctly sorting their garbage. Through the Alipay app, they can exchange the points for milk, phone cards and other things. The city is asking all the people to sort their garbage into four groups: wet, recyclable, harmful and dry.

Wet waste is also known as household waste. They are things you don’t want but that pigs can eat. Paper, glass and other things that can be reused are recyclable waste. Harmful waste includes things like medicine and batteries. Finally, any waste that’s not wet, recyclable or harmful will go in the “dry waste” bin.

Many other Chinese cities are also using this method to sort their garbage. For example, Shenzhen has been sorting its garbage into the same four groups. Students there also receive waste-sorting guidebooks that they must study.

If you don’t sort garbage, all of it will go to a landfill. These landfills can take up large areas of ground that could have been used for planting trees. The waste you throw away, such as batteries, can pollute the groundwater. Other pieces of garbage, like the metal part of a pen, can be used to make other things if they are properly recycled.
