It shows how powerful the secrets of Ancient Maya civilisation are among people. Maya civilisation ③has_been_surrounded (surround) by mystery since its rediscovery in the 19th century. The Maya built impressive palaces and temples. ④What is most extraordinary about these complex structures is how they were built without the use of wheels, metal tools or even animal power. The Maya's understanding of mathematics and astronomy was also quite ⑤amazing (amaze). On top of all this ⑥was (be) an achievement unique in the Americas at that time: a true writing system. But the greatest mystery of all is what caused the Maya to abandon most of their great cities. Some research seems ⑦to_indicate (indicate) that the Maya people themselves may have played ⑧a part in their downfall. Research also suggests that those natural disasters may have led ⑨to the decline of the Maya. Its once­great cities fell into ruin, leaving ⑩various (vary) mysteries for later people to solve. Meanwhile, the rise and fall of this civilisation must also leave us thinking about our own past, present and future. 学科网（北京）股份有限公司 $
