24、ent and future.6画线部分是现在分词短语，在句中作结果状语。译文参考玛雅人的奥秘15 岁的加拿大人威廉加杜里(William Gadoury)从小就对玛雅文明很感兴趣，他认为自己从研究古代星图中获得了一个不可思议的发现。通过比较，他发现 117 个已知玛雅城市的位置与恒星的位置相对应。基于此，他相信他发现了一个埋在丛林深处的未知的玛雅城市。虽然他的理论已经被学者们所否定，但它显示了古代玛雅文明的奥秘在人们心中是多么的有影响力。不难理解为什么。从我们现在所知的墨西哥南部延伸到美洲中部，自 19世纪被重新发现以来，玛雅文明一直被神秘所笼罩。玛雅人建造了令人印象深刻的宫殿和寺庙，包括他
25、们代表性的阶梯金字塔。这些复杂建筑的最不寻常之处是它们如何在不使用轮子、金属工具甚至动物运输的情况下建成的。玛雅人对数学和天文学的理解也相当惊人。他们把这种理解应用到玛雅历法中，精确到每年 30 秒以内。除这些之外还有一个当时美洲独一无二的成就：一个真正的文字系统。它包含 800 多个字符，其中一些符号代表动物、人和物体，另一些则代表音节。这是一个非常复杂的文字系统，到目前为止，还没有人能够完全理解它。玛雅社会在技术上是原始的，这使得它的成就更加不可思议和神秘。但最神秘的是什么导致玛雅人遗弃了他们大部分的大城市。到公元 700 年，玛雅文明达到了顶峰。然而，仅仅几代人之后，它就开始神秘地衰落。
26、城市被丛林夺回了。当欧洲人在 16 世纪初来到中美洲索要其财富时，剩下的玛雅人就住在小的定居点里。玛雅文明为何崩溃仍是个谜。是自然灾害吗？是致命的疾病吗？是城市之间的冲突吗？或者是几个不同因素的综合作用吗？一些研究似乎表明，玛雅人自己可能在他们的垮台中起了一定的作用。他们把湿地变成了种植粮食的田地，他们挖了巨大的运河系统。并且随着人口的增长，更多的土地需要用于农业，更多的树木需要用于建设。通过这种方式改变地貌，有可能是玛雅人在不知不觉中降低了应对自然灾害的能力。研究还表明，这些自然灾害可能导致了玛雅人的衰落。最近的一些研究发现，公元 700 年到 1000 年之间，热带气旋的数量比平时少得多。这很可能导致了一系列的干旱，每一次都持续了几年，其中包括公元 900 年左右的一次“超级干旱”。许多科学家认为，这些干旱是玛雅文明在不同地方开始以不同速度崩溃的主要原因。这些干旱将导致粮食短缺、冲突，最终导致城市的崩溃。不管是什么原因，玛雅文明基本上消失在丛林深处。它曾经辉煌的城市都毁灭了，留下了各种各样的谜团让后人去解开。同时，这个文明的兴衰也必须让我们思考自己的过去、现在和未来。Thank you for watching!
