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 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 anywhere using my computer or phone.”

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， 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 surfing the Internet 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 codes 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.

Modern robots are important to space exploration （探索） and are being used in different ways for several important reasons.

1 Aside from the earth， just about every surface in the solar system is unsafe for humans to explore. The air on most other planets is thin for humans， making it necessary to wear a space suit and oxygen equipment. The temperatures on these surfaces are much too hot or much too cold for any human. Plus， there would be radiation， bad weather， and a lack of gravity. Robots have much less limitation （限制） in these areas. 2

Robots are designed for collecting scientific data. 3 Important scientific projects from detecting minerals， analyzing ground samples， to finding water are all performed much quicker and accurately by robots.

The use of robots has made the cost of space exploration much less expensive than it would cost for humans to do the work. In order to successfully send humans into space， we would need to build a vehicle that can not only carry humans， but also enough food and water to keep them alive for the duration of the trip. Moreover， robots have no problems working for hours on end. 4 Robots don’t require food or water and they never need a bathroom break.

Over the past 30 years or so， there have been many different types of robots used successfully in the exploration of space. 5 They have both been successful with experiments on soil and rocks and have even found evidence of water in Mars’ history.

A. Robots never complain.

B. Robots make great explorers.

C. This is because it is moving around the earth.

D. Perhaps the most famous are Spirit and Opportunity.

E. They can process information much more efficiently.

F. They can survive much longer under these conditions.

G. There are millions of pictures taken by robot explorers.
