12、iscovery from his study of ancient star charts.Through comparison,he found that the locations of the 117 known Maya cities correspond to the positions of the stars.Based on this,he believed he had spotted an unknown Maya city buried deep in the jungle.Although his theory has been dismissedby scholar

14、the 19th century.The Maya built impressive palaces and temples,including their representative step pyramids.What is most extraordinary about these complex structures is how they were built without the use of wheels,metal tools or even animal power.2The Mayas understanding of mathematics and astronom

15、y was also quite amazing.They applied this understanding to the Maya calendar,which was accurate to within 30 seconds per year.On top of all this was an achievement unique in the Americas at that time:a true writing system.It contained more than 800 characters,with some signs representing animals,pe

17、t the greatest mystery of all is what caused the Maya to abandon most of their great cities.By 700 AD,Maya civilisation was at its peak.Yet,within just a couple of generations,it began to mysteriously decline.The cities were left to be taken back by the jungle.When Europeans arrived in Central Ameri

21、ound that there were far fewer tropical cyclones than usual between 700 AD and 1000 AD.This is likely to have led to a series of droughts,each lasting for a couple of years,including a “megadrought”around 900 AD.Many scientists believe that these droughts were the main reason why Maya civilisation b

23、.Its oncegreat cities fell into ruin,leaving various mysteries for later people to solve6. Meanwhile,the rise and fall of this civilisation must also leave us thinking about our own past,present 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

24、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

25、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。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

26、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。
