Now we can see QR codes （二维码）in many places. We use the m phone to scan （扫描）QR codes. Then we can pay bills, get more information about something, add friends and so on. QR codes are u. Do you know who invented them and w he invented them?

Before QR codes were invented, people u bar codes（条形码）. A bar code can't store（储存）so much information. A Japanese man wanted to solve（解决）the problem and he invented the QR code with his team. His n  is Masahiro Hara. 
       Maybe in the future, you will find QR codes are not good enough and you may invent another kind of code. That will be great!

    I'm Sam. I have a pen pal, his name is Li Ming. We all like reading books. He's from China, and he gives me some stamps about famous Chinese people. He also tells me something about them. I know his hobby is to collect kites, so I send him different kites from America, and tell him many stories about America.

    Last summer holiday, I went to China and visited him. He told me something about many famous places such as the Great Wall, Tian'anmen Square and the Summer Palace. I had a great time in Beijing.
