Monarch butterflies(帝王蝶) from the eastern part of North America make the most amazing journey in the insect world. Each year, this tiny creature(生物) travels up to 3,000 miles(4,800 kilometers) to its winter home in central Mexico(墨西哥). How can it fly so far? And what is the purpose of its long and dangerous trip? Scientists still don’t have an explanation.
The length of the butterflies’ trip is only one part of the mystery. The other amazing thing is that the butterflies always return to the same place in central Mexico. How do the butterflies find their way back to the same place? This is an interesting question because only every fourth generation(代) makes the trip south. In other words, the butterfly that travels to Mexico this year is the great-great-grandchild of the butterfly that traveled there last year.
Each year, four generations of a Monarch butterfly family are born. Each generation of the family has a very different life. The first generation of Monarchs is born in the south in late April. It slowly moves north, reproduces, and then dies. On the trip north, two more generations are born, reproduce, and die. Each of these generations of butterflies lives for only two to five weeks. In the fall, the fourth generation of butterflies is born. Compared to its parents, this generation has a long life. It lives for about eight months. This generation of butterflies makes the amazing journey to the winter home of its great-great-grandparents. The butterflies spend the winter there, and in the spring they reproduce and then die. Their children will be the first generation of the next circle. How amazing it is!

The Silk Road went from China to Eastern Europe. It went along the north of China, India, and Persia and ended up in Eastern Europe near today's Turkey and the Mediterranean Sea.

Besides silk, the Chinese also sold teas, salt, sugar, porcelain（陶瓷）, and spices. Most of the goods was expensive. This was because it was a long trip and traders didn't have a lot of room for goods. They bought goods like cotton, ivory, wool, gold, and silver.
Traders traveled in large caravans. They would have many guards with them.2.Most of the road was through dry land. So camels were popular animals for transport.
Although there was some trade between China and the rest of the world for some time, the silk trade developed quickly during the Han Dynasty which ruled from 206 BC to 220 AD.3.During this time the Mongols controlled most of the trade road, and Chinese traders travel safely.

“Pisin” means “pidgin”. A pidgin language is one which is a mixture of two other languages, while a creole is a pidgin language that has become the mother language of a community. Tok Pisin started as a pidgin language and became a creole language.
Although the majority (大多数) of Tok Pisin vocabulary (词汇) comes from English, it also includes words from German, Portuguese, Latin and a number of other languages.
