(课件网) 主题语境：人与自然———探究未知 本单元的写作任务是写一篇与自然之谜有关的文章。介绍自然之谜属于说明类文章，是高考英语写作中一种常见的考查形式。它要求从科学文献或权威机构搜集相关资料，并加以调查、整理，清楚地介绍自然之谜发生的时间、地点、经过等情况，使读者对此有一个完整、准确的了解。 第一部分：开门见山，引入话题。 1.The largest pyramid of all，also known as the Great Pyramid of Cheops (or Khufu)，was built around 4，600 years ago. 2.The topic of my speech is “The unexplained—the Loch Ness monster”. 3.In the north of Scotland there is a lake called Loch Ness，which is the deepest lake in the UK. 4.There are many unexplained mysteries of the natural world，of which the Sanxingdui Ruins is a particular one. 5.Many local citizens claim that they witnessed a big monster living in the water and weighing at least 1，000 kilos. 第二部分：列举猜想并给出解释。 1.Some believe that supernatural forces are responsible，while others put the accidents and disappearances down to coincidence. 2.What makes it more mysterious is that hundreds of perfectly round stones were found deep in a forest，but no one knows how nature made them. 3.Some people believe that a lake suddenly drying up was probably caused by supernatural things，such as angry spirits or magic from the earth. 4.The natural factors like gas bubbles rising from the ocean floor should also be taken into account because they can make water less dense and pull ships underwater. 5.Scientific theories，meanwhile，include pilot errors when pilots are trying to navigate the area，and huge “rogue waves” caused by terrible storms. 第三部分：得出结论。 1.Though scientists worldwide are still attempting to get to the bottom of this problem，no conclusive proof has been able to throw light on it so far. 2.Maybe in the future we can find the answer with the development of science and technology. 假定你是李华，埃及胡夫金字塔(the Pyramid of Khufu)是如何建造的是人类史上最大的谜题之一。有人说它是大量的奴隶建造的； 有人甚至认为它是外星人建造的。请用英语写一篇80词左右的短文向你校英语报的“The Unexplained”专栏投稿，要点包括： 1.胡夫金字塔的神奇之处(由230多万块巨石砌成； 平均每块重2.5吨)； 2.关于胡夫金字塔建造之谜的猜测； 3.相信这一谜题终将被解开。 [审题谋篇] [遣词造句] Ⅰ.对接单元词汇 1. 金字塔 2. 文明(社会) 3.
