Egypt is the country that people usually associate of pyramids but there are pyramids in many others places around the world. One of these places are the island of Tenerife, which is in the Canary islands. There are six steps pyramids near the town of Guimar in the south of the island. Nevertheless, these pyramids, which are made from black volcanic stone, are very controversially. Many scientists believe the structures, which were only discovered fairly recently, are simply natural stone terraces and not a mysterious wonderful of ancient times. Thor Heyerdahl, the famous Norwegian researcher, whom spent the last years of his life on Tenerife, claimed the pyramids are, in fact, made by humans who had used building techniques that were similar with those used to build pyramids in Mexico, Peru and ancient Mesopotamia. 0. ____with___ 1. ___________ 2. ___________ 3. ___________ 4. ___________ 5. ___________ 6. ___________ 7. ___________ 8. ___________ 9. ___________ 10. __________
