A road is just like a bridge between two places. The Silk Road has been a bridge between East and West. But the Silk Road is not a single route! It is a series of trade and cultural transmission routes. From the time Zhang Qian opened up the world-famous Silk Road during the Han Dynasty, until the Yuan Dynasty, it enjoyed a history of about 1,600 years.

 This ancient road begins at Chang'an (now Xi'an), and it reaches Dunhuang, where it divides into three, the Southern Route, Central Route and Northern Route. And then it ends in Eastern Europe, near the Mediterranean Sea(地中海). The Silk Road is about 6,500 kilometers long. It goes across one-fourth of the planet. (3)In fact, there is another trade road which is called the “Silk Road on the Sea” in the southwest of China.

 The Silk Road was very important to both China and the rest of the world. Besides trade, knowledge about science, arts and technologies were shared across the Silk Road. The Four Great Inventions of China was introduced to the West and Chinese also knew about the religions of the West. (4)In this way, languages and cultures developed and influenced each other. Today, places along the Silk Road are great places of interest, such as the Terracotta Warriors in Xi'an and Mogao Grottoes in Dunhuang, Gansu.

    I was coming back home late at night in a ”Sharing” minivan. In Hyderabad, India, it is a cheap and quick means of transport. The van drivers ply (揽客) as many as 13 people at times in a vehicle which is designed for the transport of 8 people．Our van was crowded as well. People were getting off and on at many places.

    On the journey, one girl waved her hand to ask the driver to stop. While getting down, she tripped and fell．None of us notice it，as it was dark. The driver was waiting for her to pay. It was then that we saw the girl was on her knees by the side of the road. Another passenger and l got down and held her up．

    Even in pain, the girl held up a note and asked us to pay the driver．The other passenger took the note and paid the driver．My stop was a few hundred meters away. I decided to stay with her till she was fine. I paid the driver for myself and he took off with the other passengers.

    I neither knew her nor did I know what to do, but I was there, saying some comforting words to a stranger in pain. I asked her to stand still for a few minutes. We then looked for a place for her to sit. From out of nowhere, her friend joined us.

    We made her sit in a nearby grassland and her friend rushed to get a taxi. In the meantime, she examined her leg and her ankle had swollen up (肿胀). It looked like a sprain (扭伤). Once her friend came back, they took the taxi and rushed to a hospital. Before they left, the girl thanked me and said they could manage as it was only a small sprain.

    I do not know if I did enough. But I feel I gave some comfort to her in a small way.

    Hello, I'm Lin Tao. This is my school. It's a big and beautiful school. There is a big play ground. The gym is next to the playground. In front of the gym, there are science labs. Behind the gym, there is a library. So we can see the gym is between the science labs and the library. In the library, there are many books. Look! This is our teaching building, and there are 48 classrooms in it. In my class, there are 56 students.34 of them are boys, the rest are girls. On the right of the teaching building, there is a dining hall, and we often have lunch there. Teachers' offices are in front of our teaching building.

    In America, some teenagers are interested in charity. They are willing to help others. Some teenagers even set up their own charity group. Shreya Papneja is one of them.

    Shreya Papneja is 13 years old. She started a charity group called Children's Health Awareness Program in Schools. Her charity group helps kids make healthy choices and tries to stop childhood obesity(肥胖).

    A doctor once told Papneja that more than one-third of children were overweight. She did a lot of research about it. Then she made a website to teach other children about exercise and healthy eating.

    She does a lot of things for her charity group when she is free. For example, she often organizes different activities at schools around her hometown.

    I know how hard it is to make a change, but I won't give up. At least I've changed a lot. Now I eat more healthy food instead of junk food," she said to a reporter.
