D Strange stones of Costa Rica 哥斯达黎加的石球究竟是不是人类的杰作? One of the strangest mysteries in archaeology was discovered in the Diquis River delta, in southern Costa Rica. Since the 1930s, hundreds of stone balls have been found. They range in size from a few centimetres to over two metres. Who made these perfect spheres and how they made them remains a mystery. Some researchers believe the stones were made by extreme heating followed by cooling. People could have polished the spheres with sand or leather. The ancient Costa Ricans had no written language so there is no written record of just how they made the spheres. Almost all are made of granite , a hard stone created by volcanoes . The granite quarries were 25 to 30 miles away from the largest stones, which weigh more than 10 tons each. Nobody knows how people moved them. Many of the stones have been found near the remains of houses or graves . Some believed that the stones contained hidden treasures and a few have been smashed but nothing has been found inside. Despite these losses, the National museum of Costa Rica has recorded 130 spheres. However, many stones are not included because they have been removed from their original sites and used as ornaments in homes, gardens and churches. Clearly, there are also many stones that lie undiscovered. 68. The stones were discovered A. near the volcanoes B. in the south Costa Rica C. in a grave D. churches 69. The passage mainly tells us . A. the stones are of great value B. the stones proved to be made by non-humans C. the stones are a mystery D. the stones are ornaments 70. The writer in this passage. A. admires the spheres very much. B. doesn’t believe the spheres were once made by humans C. tells us of a discovery D. describes the spheres nicely 71. The underlined word “polished refers to . A. buried B. wrapped C. made shining D. made big 查看更多
