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 in on WeChat（微信）. 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.”
The QR codes can be sent to Mr. Guo by email, QQ and WeChat. When Guo scans（扫描）his students’ QR codes, their homework appears on his phone. He finds that their homework becomes more creative（创新的）, 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. “48 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 allows them to check the students’ work at any time. And it’s also an easy way to share homework with other students.

The idea that red means stop and green means has influenced our lives in more ways than just traffic signals(信号). We have been taught from a young age that the color red means danger and green means it's okay to move forward. But why were those colors chosen for traffic lights in the first place? For something we have to look at every day, why couldn't they have been prettier colors?
Well, it's import to know that before traffic lights for cars, there were traffic signals for trains. At first, railway companies used red to mean stop, white to mean go, and green to mean warn. As you could imagine, trains ran into a few problems with white meaning go. For example, one train mistook a bright star for a white light and something unexpected happened. Because of that, railway companies finally moved green meaning go and used yellow to mean warn. And it's been that way ever since.
Red has always been a color that mean danger, long before cars were even around. This most likely started because it's the color with the longest wavelength(波长) so it can be seen somewhere farther than other colors.
But, believe it or not, yellow was once used to mean stop. Back in the 1900s, some stop signs were yellow because it was too hard to see a red sign in a poorly lit area. Finally, highly reflective materials(高反射材料) were developed and red stop signs were born. Since yellow can be seen well at all times of the day, school zones, some traffic signs, and school buses continue to be printed yellow.
So next time you are impatiently waiting at a traffic light, don't get so mad at them, they've certainly come a long way.
