Module 6 Unexplained Mysteries of the Natural WorldIn Chinese myths dragon is a positive symbol, indicating being generous, wise and noble. Besides, they can bring goodfortune. Dragon has a good reputation. Inemperors' robes, there was a gold dragon with five sharp claws. While in the western countries, dragon is considered to be a frightening creature. Due toits fierce appearance and the huge destruction, dragon has a bad reputation. Some people say dragon died out long time ago, but in fact, dragon doesn'texistin the world. It is an animal made up by man.Dragon is an ancient mystery. But recently, another mystery has caught our attention. The “Monster of Lake Tianchi” has been back in the news since several sightings. Tianchi is a volcanic lake and covers an area of about ten square kilometers. Some tourists here claimed that they saw a mysterious creature with two huge hornsunder the calm surface of the lake. It was in the middle of the lake for several minutes and soon dived into the water and disappeared. The experts are sceptical about the description, because the water temperature in the lake is so low that such a large living creature is unlikely to live in the lake. They can't adapt to such low temperature. The experts hope to find some evidence to throw light on the mysterious phenomenon.在中国的神话故事里龙是一种正面的象征，象征着慷慨、智慧和高贵。除此之外，它们还能带来好运。龙的名声很好。在皇帝的袍子上，总有一条五爪锐利的金龙。而在西方国家里，龙被认为是一种吓人的动物。因为它残暴的外表以及巨大的破坏力，龙的名声不好。有人说龙在很久以前就灭绝了，但实际上它在世界上根本就没有存在过。它是人们杜撰出来的一种动物。龙是一个古老的谜团。但是最近另一个谜团吸引了我们的注意。几次目击之后，“天池怪物”再次成为新闻。天池是一个火山湖，占地约 10 平方千米。有些到这儿的游客声称他们看到在平静的湖面下有一个长有两只巨角的神秘生物。它在湖中央待了几分钟，然后很快潜入水下，消失了。专家们对此描述表示怀疑，因为湖水温度非常低，像这样的大型生物不可能生活在湖里。它们适应不了这么低的温度。专家们希望找到证据，弄清这个神秘的现象。
