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 Mr. 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 cheek their work anywhere using my computer or telephone. "

    The QR codes can be sent to Mr. Guo by email, QQ and WeChat. When Mr. Guo scans (扫描) his students' QR codes, their homework appears on his phone, lie finds that their homework becomes more creative, with many pictures, music and even videos.

    Mr. 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 Tingling, a student of Mr. Guo's.

    "The paper is not easy to keep, hut the code is easy to keep and share." Mr. 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 codes when they hand in their work, which doesn't take them too much time.  Also for teachers, it allows them to cheek the students' work at any time.  And it's also an easy way to share homework with other students.

    A traveler in South Africa once set out on a long journey. When crossing a wide plain(平原), far from home, he saw a lion at a distance. The lion saw him at the same time, and followed him slowly.

    When the traveler walked fast, the lion walked fast! When he stopped, the lion stopped! The man realized that the lion meant to follow him until the dark, and then attack(攻击) him.

    He was not able to run away from the lion because the lion ran faster than him. So he thought of a plan to fool it.

    He came to a large rock. He hid behind the rock, where the lion could not see him. Then taking a stick which he could find there, he put his coat and his hat on it, in order to make them look like a man. He then placed the stick with the coat and the hat standing in the ground above the rock. He then left quietly.

    The lion stopped and watched the coat and the hat, at a distance. At nightfall, it jumped onto the coat and the hat to try to kill the man.

    But the traveler was already far away. Before long, he reached his own home.
