China has a long history of creating amazing inventions that changed the world. Here are the four most important ones. Paper Paper was invented by Cai Lun in 105 AD． Before paper, people wrote on heavy bamboo or expensive silk. Cai Lun used tree bark, bamboo, and old cloth to make cheap, thin paper. This invention made it easy to spread knowledge. Today, paper is still used all over the world for books, newspapers, and art. Movable Type Printing Movable type printing was invented by Bi Sheng in the 11th century. Before this, people used woodblock printing, which was slow and expensive. Bi Sheng made small clay characters that could be rearranged to print different pages. This invention made books cheaper and easier to produce. It helped spread education and ideas across China and later to Europe. The Compass The compass was invented during the Han Dynasty(206 BC­220 AD). At first, it was used for fortune­telling. Later, sailors used it to find their way at sea. The compass made long­distance travel possible. It helped European explorers discover new lands during the Age of Discovery. Gunpowder Gunpowder was invented by Chinese alchemists(炼金术士)in the 9th century. They were trying to make a potion for eternal life when they accidentally created gunpowder. At first, it was used for fireworks. Later, it was used in weapons like cannons(大炮)and guns. Gunpowder changed warfare and led to the creation of modern weapons. These inventions have changed the world a lot. They made it easier to share ideas, travel long distances, and protect countries. Without these inventions, the world would be very different today. In addition, great inventors are curious, creative, and persistent. They ask questions, try new things, and don't give up when they fail. Cai Lun, for example, tried many different materials before he found the right way to make paper. We should learn from ancient hardworking people. 根据以上内容，选择最佳答案。 ( )1.Who invented movable type printing? A．Cai Lun.　　　　　 B．Shen Kuo. C．Zhang Heng. D．Bi Sheng. ( )2.When was the compass invented?
