Human_beings_should_respect_nature_and_not_violate_the_law_of_its_development._On_the_one_hand,_we_should_follow_the_natural_law_and_believe_in_the_survival_of_the_fittest._On_the_other_hand,_we_should_actively_transform_the_world_around_us_and_bravely_fight_against_all_kinds_of_disasters_as_much_as_possible. 2．What can we do to help protect modern civilisation? We_should_attach_great_significance_to_our_modern_civilisation._As_we_all_know,_it_is_not_so_easy_for_us_humans_to_have_the_civilisation_that_we_have_got_today.We_should_spare_no_effort_to_protect_our_modern_civilisation.In_no_way_should_we_make_profits_at_the_cost_of_our_homeland. |阅|读|技|能|提|升| 本文的语篇类型为说明文。课文标题“The Mysteries of THE MAYA”直接点明了文章的主题“玛雅之谜”。文章第一段以加拿大一个十五岁青少年的发现为引子导入主题，然后逐层剖析了玛雅文明消失的可能原因及对人类的启示。文章的最后一段是总结提升段，阅读时应重点分析，把握文章的深层内涵。 (一)赏用词之妙 1．The Maya built impressive palaces and temples, including their representative step pyramids. 赏析：本句中的修饰词impressive及representative写出了玛雅文明曾经的辉煌。 2．The Maya's understanding of mathematics and astronomy was also quite amazing. 赏析：此处的quite amazing充分传达了作者对玛雅文明的赞叹之意。 3．Research also suggests that those natural disasters may have led to the decline of the Maya. 赏析：本句中的may表明了此处只是对玛雅文明衰落的原因的一种推测，语气并不确定。 ①Equally_impressive_is Li Bai's free expression of strong feelings, which breathes vitality into the lifeless objects he describes. 同样令人叹服的是李白对强烈情感的恣意抒发，他笔下的万物都被赋予灵性。　　 ②The sunset painted the sky in shades of orange and purple, and_it_was_quite_amazing how the whole village seemed to glow in that warm light. 夕阳将天空染成橙紫相间的色调，整个村庄在那温暖的光芒中仿佛都在发光，这相当令人惊叹。 (二)赏句式之高 1．The fact that Maya society was technologically primitive makes its achievements all the more incredible and mysterious. 赏析：本句中使用了that引导的同位语从句，具体解释了玛雅社会的科技水平十分原始这一事实，反衬了玛雅的成就令人难以置信、神秘莫测。 2．Whatever the reasons, Maya civilisation largely disappeared within the deep jungle. 赏析：本句中使用了whatever引导的让步状语从句的省略形式，传达了作者对曾经辉煌的玛雅文明最终沦为废墟的深深叹惜之情。 ①No matter what happens, always have_the_belief_that_the_things_you_desire _may_not_happen_today,_but they will happen. 无论发生什么，始终要抱有信念：你渴望的事情即使今天没有发生，但迟早终会发生。 ②It was this unique experience that made me understand whatever_difficulty_we_are_faced_with,_we should by no means give up our hope. 正是这次独特的经历让我明白：无论我们面临什么困难，都不应该放弃希望。　　 (三)赏描摹之韵(场景描写) 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. 赏析：此处at its peak与 mysteriously decline形成鲜明对比。同时，副词yet突出了这种转折差，激发读者探究玛雅文明衰落的缘由的兴趣。最后一句中的 were left to be taken back by the jungle生动形象地展现了玛雅文明被丛林蚕食取代的场景。 It began with a low rumbling sound like thunder. Soon the rumbling grew_into a roar. The ground shook and deep cracks opened_up in the streets.Huge buildings collapsed, sending_clouds_of_dust_into_the_air. Within seconds the town lay_in_ruins,_a terrible choking smell filling the air. (地震)开始像打雷似的发出低沉的轰鸣声。不久，轰鸣声变成了咆哮。大地摇晃，街上出现了很深的裂缝。高楼倒塌，在空中扬起了团团灰尘。几秒钟的工夫，这个城镇就沦为一片废墟，空气中弥漫着令人窒息的可怕气味。 　　　 (四)赏逻辑之巧 第四段中第二至五句连用四个疑问句，引发读者思考古玛雅文明衰落的原因。第六句给出解答，同时点明本段主旨，接着后面几句对此进一步解释说明。这种段落组织模式既有利于深入阐明主题，又能极大地调动读者的阅读兴趣。 打开人类历史的画卷，从浩瀚神秘的宇宙到绚丽多姿的地球，从远古生命的诞生到人类成为地球的主宰，我们可以发现：人类从未停止过对未知世界的探索。但世界之大，无奇不有。在科学已经有了飞跃式发展的今天，我们仍有许多难题没有找到答案。在人类的未知探索之路上，我们仍需砥砺前行。 Yeti, Bigfoot and the Wild Man of Shennongjia For centuries, people have reported seeing a wild creature in the Himalayas called Yeti. The Yeti is said to be a large, hairy animal that walks on two feet like a human being.People believe that Yetis sometimes come down from the mountains to attack villagers. In 1998, an American mountain climber said that he saw a Yeti on the Chinese side of the Himalayas. “It walked like a human, but it had thick black fur and was about six feet tall with huge shoulders, very long arms and large hands，” he said. In 2007, an American TV team saw Yeti tracks 33 centimetres in length in the snow near Mount Qomolangma. They made copies of these tracks and had them examined by a scientist in the USA. He reported that they looked like the tracks of a similar creature, called Bigfoot, which some people believe lives in the forests of the north­west of the USA. Yeti and Bigfoot are similar to a creature known as the Wild Man of Shennongjia. dozens of reports that people have seen a Wild Man in the Shennongjia Nature Reserve in western Hubei Province, China. In one case, a group of engineers ran after the creature, which moved with amazing speed and strength. Large tracks have also been discovered which some people say belong to the Wild Man. Because of these reports and the tracks, there have been several organized searches for this creature, but no strong evidence for its existence has ever been found. Dr Grover Krantz, a scientist from Washington State University, studied reports of such strange creatures for many years. He became convinced they exist. He believed that these creatures are linked to a common ancestor, . In his opinion, this animal made its way to other parts of the world, and continues to survive even today. Scientists hope that the mystery will be solved one day. If such creatures really exist, we might have the chance to see one with our own eyes.
