参考范文 
A 15-year-old Canadian, William Gadoury, said he had found out an unknown Maya city. The Maya civilisation made many great achievements at its peak, such as complex structures, mathematics, astronomy as well as a writing system, but to people's surprise, it went into decline for some unknown reasons. Whether it collapsed because of man-made or natural factors, the mysterious Maya civilisation left us thinking about our own past, present and future.

玛 雅 文 明
玛雅文明,是分布于现今墨西哥东南部、危地马拉、洪都拉斯、萨尔瓦多和伯利兹国家的丛林文明。虽然处于新石器时代,却在天文学、数学、农业、艺术等方面都有极高成就。玛雅文明与印加文明及阿兹特克文明并列为美洲三大文明。

The Mysteries of THE MAYA
Intrigued by Maya civilisation from a very young age, 15-year-old Canadian William Gadoury thought he had made an incredible discovery 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(1). Based on this, he believed he had spotted an unknown Maya city buried deep in the jungle(2). Although his theory has been dismissed by scholars, it shows how powerful the secrets of Ancient Maya civilisation are among people.
玛雅的奥秘
15岁的加拿大人威廉·甘德瑞从很小的时候就对玛雅文明产生了浓厚的兴趣,他认为自己通过研究古代星图有了一个令人难以置信的发现。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。基于这一点,他相信他发现了一个埋藏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否定,但它表明了古代玛雅文明的秘密在人们心中是多么有影响力。

(2)本句为宾语从句,省略了引导词that,其中buried deep in the jungle为动词-ed形式作后置定语。
  It isn't difficult to see why. Extending south from parts of what we know as Mexico(3) into Central America, Maya civilisation has been surrounded by mystery since its rediscovery in the 19th century. The Maya built impressive palaces and temples, including their representative step pyramids. What is most extraordinary about these complex structures(4) is how they were built without the use of wheels, metal tools or even animal power(5). The Maya's understanding of mathematics and astronomy was also quite amazing. They applied this understanding to the Maya calendar,which was accurate to within 30 seconds per year(6). 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, people and objects and others representing syllables. It was a writing system so complicated that, so far, no one has been able to interpret it completely(7).
  不难看出其中的原因。玛雅文明从我们所知的墨西哥部分地区向南延伸到中美洲,自19世纪重新发现以来一直有许多未解之谜。玛雅人建造了令人印象深刻的宫殿和寺庙,包括具有代表性的阶梯金字塔。这些复杂建筑最令人惊奇的地方在于它们是如何在不使用轮子、金属工具甚至畜力的情况下被建造的。玛雅人对数学和天文学的理解也相当惊人。他们将这种理解应用于玛雅历法,该历法的精确度极高,每年的误差在30秒内。除此之外,当时美洲还有一项独一无二的成就:一套真正的书写系统。它有800多个字符,一些字符代表动物、人和物体,另一些字符代表音节。这是一套如此复杂的书写系统,以至于到目前为止还没有人能够完全解释它。

  The fact that Maya society was technologically primitive(8) makes its achievements all the more incredible and mysterious. But 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 America in the early 16th century to claim its riches(9), the remaining Maya people were living in small settlements.
  玛雅社会在技术上是原始的,这一事实使它的成就变得更加令人难以置信和神秘。但最大的谜团是什么导致玛雅人抛弃了他们的大部分大城市。到公元700年,玛雅文明达到顶峰。然而,在短短几代人的时间里,它开始神秘地衰落。这些城市被丛林夺回。当欧洲人在16世纪初抵达中美洲索取其财富时,剩下的玛雅人就住在小的村落里。

(9)when引导时间状语从句。
  Why Maya civilisation collapsed(10) remains a mystery. Was it a natural disaster A deadly disease Conflicts between cities Or was it a combination of several different factors Some research seems to indicate that the Maya people themselves may have played a part in their downfall(11). They had turned wetlands into fields for growing grains, and had dug huge canal systems. As their population expanded(12), yet more land was needed for agriculture and more trees for construction. By changing the landscape in this way, it is possible that the Maya people unknowingly reduced their ability to deal with natural disasters(13).
  玛雅文明为什么崩溃仍然是个谜。是因为自然灾害,致命的疾病,还是城市之间的冲突 或者是几个不同因素的综合作用 一些研究似乎表明,玛雅文明的衰落可能是玛雅人自身造成的。他们把湿地变成了种粮食的田地,还挖了巨大的水渠系统。随着人口的增加,农业需要更多的土地,建设需要更多的树木。通过这种方式改变地形,玛雅人可能在不知不觉中降低了他们应对自然灾害的能力。

(10)why引导主语从句。

(12)as引导时间状语从句。
(13)it为形式主语,真正的主语是that引导的从句。
  Research also suggests that those natural disasters may have led to the decline of the Maya. Some recent studies have found that there were far fewer tropical cyclones than usual between 700 AD and 1000 AD(14).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 began to collapse at different rates in different places(15). These droughts would have led to food shortages, conflicts and, ultimately, the downfall of the cities.
  研究还表明,那些自然灾害可能导致了玛雅文明的衰落。最近的一些研究发现,在公元700年到公元1000年之间,热带气旋的数量比往常要少得多。这可能导致了一系列旱灾,每一次旱灾都持续好几年,包括大约在公元900年的一次“特大旱灾”。许多科学家认为,这些旱灾是玛雅文明开始在不同地方以不同的速度崩溃的主要原因。这些旱灾将导致粮食短缺、冲突,并最终导致城市的衰败。

  Whatever the reasons(16), Maya civilisation largely disappeared within the deep jungle. Its once-great cities fell into ruin, leaving various mysteries for later people to solve(17). Meanwhile, the rise and fall of this civilisation must also leave us thinking about our own past, present and future.
  不管什么原因,玛雅文明基本上消失在了丛林深处。它曾经伟大的城市变成废墟,留下了各种各样的谜团供后人去解开。同时,这种文明的兴衰也必须让我们思考我们自己的过去、现在和未来。
