    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.

    When it comes to the letter grade on your test or homework, you might notice that there is no letter E. Have you ever thought about why that is so?

    In the A, B, C, D and F grading system, the first four letters are typically considered passing grades. An F in this system simply stands for "fail". The word "fail" happens to start with the letter F, which seems to leave out the letter E.

    The first college in the US to use a letter grading system like the ones we use today is Mount Holyoke College. In 1897, they began to use the following grading scale;

    A: 95-100% (excellent)         B: 85-94% (good)      C: 76-84% (fair)

    D: 75%( nearly passed)         E: below 75% (failed)

    We can see the inclusion of E instead of F.

    Gradually, the letter grading system became more popular all over the US. However, many schools decided to drop the E grade and go straight to F. There is no evidence(证据) to really support this, but one possible explanation is that teachers were worried that some students and parents might mistake E for "excellent".

    Why do we have letter grades? Well, part of the reason is that they made grading simpler during a time of great change for schools. As the 20th century began, growing cities and an increase in immigration led to larger school classrooms. Most teachers at that time thought this new letter grading system was an easy, fair and clear way to grade students.

    Today, more and more people think that letter grades don't fully show students' learning. However, as teachers try to improve grading methods, many parents continue to prefer the letter grades they got as kids, as they are familiar and easy for parents to understand. So while they might not be perfect, the letter grades probably aren't going away any time soon.

    An 11-year-old blind girl is proud of walking alone every day to and from school. Why? She has to walk past so many barriers (障碍物) in her way. The girl's home is near the school, yet her mother follows her without letting her know.

    The case of the girl shows the barrier-free facilities (设施) are not enough in her city. Many other cities are short of barrier-free facilities as well. There's no well-designed path for the blind. In fact, in the early 2000s, some cities started to build barrier-free facilities for disabled people. However, almost 20 years later, only a few large cities have had facilities of high quality.

    It's common that sidewalks are taken up with barriers. Few workers are sent to move them away, so it's dangerous for the blind to walk on them. Also, some other barrier-free facilities are badly destroyed（毁坏）. Only a few workers are assigned (分配) to do the task of repairing the broken ones.

    Some ideas can make a difference-build more barrier-free facilities and employ more of them require money. In a word, more money is needed to carry on with the work. It's our duty to make life easy for disabled people, so that they can live without barriers some day.
