The idea that red means stop and green means has influenced our lives in more ways than just traffic signals(信号). We have been taught from a young age that the color red means danger and green means it's okay to move forward. But why were those colors chosen for traffic lights in the first place? For something we have to look at every day, why couldn't they have been prettier colors?

Well, it's import to know that before traffic lights for cars, there were traffic signals for trains. At first, railway companies used red to mean stop, white to mean go, and green to mean warn. As you could imagine, trains ran into a few problems with white meaning go. For example, one train mistook a bright star for a white light and something unexpected happened. Because of that, railway companies finally moved green meaning go and used yellow to mean warn. And it's been that way ever since.

Red has always been a color that mean danger, long before cars were even around. This most likely started because it's the color with the longest wavelength(波长) so it can be seen somewhere farther than other colors.

But, believe it or not, yellow was once used to mean stop. Back in the 1900s, some stop signs were yellow because it was too hard to see a red sign in a poorly lit area. Finally, highly reflective materials(高反射材料) were developed and red stop signs were born. Since yellow can be seen well at all times of the day, school zones, some traffic signs, and school buses continue to be printed yellow.

So next time you are impatiently waiting at a traffic light, don't get so mad at them, they've certainly come a long way.

The Silk Road is the name of different roads that connected Europe, Africa and Asia long ago. It was named by F. von Richthofen, who was a famous German geographer. Scientists believe people began to travel the Silk Road about 3,000 years ago. People reached these different places along these roads. By the time the Chinese silk trade became important in the world, the Silk Road covered almost 7,000 kilometers. It went from Rome to China, which is from the West to the Far East.

Businessmen travelled along the Silk Road to carry silk, of course. They also carried and traded other things like spices(香料), cloth, jewels and gold.

Along and around these ancient paths(小路), have come many fascinating and mysterious stories.

It is said that Roman soldiers who lost a war travelled through central Asia. They decided to live somewhere near the ancient Chinese villages. Some of these Romans married local Chinese women and the stories of the blondhaired, blueeyed tribes of China was started.

Some historians believe that the people of Kashmir were taken away from their country Israel. They were prisoners(俘虏) of war almost 2,800 years ago. People say that these people travelled along the Silk Road. They kept their Jewish way of life for a long time.

During its busiest period, the Silk Road allowed people from many different cultures and countries to meet each other and mix. The Silk Road allowed the sharing of valuable things and new ideas. It included people and trading goods from different areas. All these peoples travelled the Silk Road, and they shared goods, stories, languages. and cultures.

In modern times, the old Silk Road routes(路线) are still used, but now they are crossed by trains instead of camels and horses. There is even a Silk Route Museum in Jiuquan in China.  It has over 35,000 objects from all along the Silk Road. In this way, China protects the history of many countries and peoples.
