❶ 罗马斗兽场英文怎么说
罗马斗兽场英文是：The Roman Colosseum
罗马斗兽场在建筑史上堪称典范的杰作和奇迹，以庞大版、雄伟、壮观著称于世权。现在虽只剩下大半个骨架，但其雄伟之气魄、磅礴之气势犹存。斗兽场平面呈椭圆形，占地约2万平方米，外围墙高57米，相当于现代19层楼房的高度。该建筑为4层结构，外部全由大理石包裹，下面3层分别有80个圆拱，其柱形极具特色，按照多立克式、爱奥尼式和科林斯式的标准顺序排列，第4层则以小窗和壁柱装饰。场中间为角斗台，长86米，宽63米，仍为椭圆形，相当于一个足球场那么大。角斗台下是地窖，关押猛兽和角斗士。角斗台周围的看台分为3个区。底层的第一区是皇帝和贵族的座席，第二层为罗马高阶层市民席，第三层则为一般平民席，再往上就是大阳台，一般观众只能在此处站着观看表演了。场内看台共可容纳观众5万多人，底层地面有80个出入口，可确保在15分钟至30分钟内把场内5万观众全部疏散离场。斗兽场的建筑师究为何人，现在还是个未知数。有人认为可能是后来建筑多米斯亚诺宫的建筑师拉比利奥，但已无从查考。

发展旅游业，还能增长当地的就业机会，使更多的人有业可从，解决了社会中就业的一大难题，降低社会制安事件的发生频率.同时， 各地游客的进入， 增长了当地居民和外地人的接触和交往， 促进了相互间的文化交流， 扩大了视野， 提高了文化素养.发展国内旅游业还可以促进其他产业的发展.旅游业的发展能 *** 旅游者的消费，从而可以形成和扩大新的消费市场。 旅游对经济环境的有利影响是最为显著的，旅游业和其他产业相比，是一个投资少，见效快，无污染 的产业，同时，旅游业还能带动其他产业的发展，这就使旅游业对于该地区国民经济收入具有重大的意义. 旅游业对生态环境也有明显的有利影响.随着旅游业的日益发展，不断地开发旅游资源，其中有不少旅游资源原来就存在一些生态问题，，在旅游资源开发中，便可采取旅游生态建设和污染治理的措施，使开发出来的旅游资源比原来的生态环境质量更高，即旅游开发美化了生态环境.旅游业还能保持生态环境.旅游资源开发出来进入利用阶段，若能科学地管理，能使当地生态环境进入良性循环. 发展国内旅游业对于激发人民的爱国主义热情，增进人们的身体健康，提高生活质量具有较大的作用。
旅游者游览祖国锦绣山河和名胜古迹，对其开阔眼界，陶冶情操，扩大信息交流，增强身心健康都有积极的作用。尤其是在青少年中开展爱国主义教育，国内旅游发挥的作用更为明显。
再次，发展内旅游还可以促进思想观念的更新，从而提高人民的素质。国内旅游发展所形成的游客流是信息流、观念流的载体。

愿意的帮一下，谢谢 旅游区的旅游气氛环境是由当地的自然环境，以及反映当地历史、地方或民族气息的环境烘托出来的，这其中，当地的环境和文化以及历史起了很大的作用。游客在欣赏大自然美景中，也要注意遵守社会公德。
游客自身也是风景的组成部分，不文明的行为举止不仅会玷污美丽的风景，也会破坏他人游览时的心情。和谐是大家共同的心声，为了让人人都能尽其游兴，每一名游客都不能放纵自己，应多一份谦让，多一份风度，营造一个彼此友善、相互谦让的良好旅游氛围。

❺ 【悬赏50分】求碧玺的英文简介
Today, gem and specimen tourmaline is mined chiefly in Brazil and Africa. Some placer material suitable for gem use comes from Sri Lanka. Some fine gem and specimen material has been proced in the US, with the first discoveries having been made in 1822, in the state of Maine. California became a large procer of tourmaline in the early 1900s. The Maine deposits tend to proce crystals in raspberry pink-red as well as minty greens. The California deposits are known for bright pinks, as well as interesting bicolors. During the early 1900s, Maine and California were the worlds largest procers of gem tourmalines. The Empress Dowager Tz'u Hsi, the last Empress of China, loved pink tourmaline and bought large quantities for gemstones and carvings from the then new Himalaya Mine, located in San Diego County, California. [4]
Almost every color of tourmaline can be found in Brazil, especially in the Brazilian states of Minas Gerais and Bahia. In 1989, miners discovered a unique and brightly colored variety of tourmaline in the state of Paraíba. The new type of tourmaline, which soon became known as paraiba tourmaline, came in unusually vivid blues and greens. These colors were often described as "neon" since they appeared to glow. Brazilian paraiba tourmaline is usually heavily included. Much of the paraiba tourmaline from Brazil actually comes from the neighboring state of Rio Grande do Norte. Material from Rio Grande do Norte is often somewhat less intense in color, but many fine gems are found there. It was determined that the element copper was important in the coloration of the stone. The demand and excitement for this new material, which has fetched more than $50,000 per carat, earned more respect for the other colors of tourmaline. In the late 90s, copper-containing tourmaline was found in Nigeria. The material was generally paler and less saturated than the Brazilian materials, although the material generally was much less included. A more recent African discovery from Mozambique has also proced beautiful tourmaline colored by copper, similar to the Brazilian paraiba. While its colors are somewhat less bright than top Brazilian material, Mozambique paraiba is often less included and has been found in larger sizes. The Mozambique paraiba material usually is more intensely colored than the Nigerian. There is a significant overlap in color and clarity with Mozambique paraiba and Brazilian paraiba, especially with the material from Rio Grande do Norte. While less expensive than top quality Brazilian paraiba, some Mozambique material sells for well over $5,000 per carat, which still is extremely high compared to other tourmalines.
Tourmaline mineral (~ 10 cm tall)Another unique variety that is also highly valued is chrome tourmaline, a rare type of dravite tourmaline from Tanzania which occurs in a very rich green color caused by chromium, the same element which causes the green in emerald. Of the standard Elte colors, generally blue indicolite gems are the most expensive, followed by green verdelite and pink to red rubellite. There are also yellow tourmalines, sometimes known as canary tourmaline. Ironically the rarest variety, colorless achroite, is not appreciated and is the least expensive of the transparent tourmalines. In addition to Brazil, significant amounts of tourmaline are also mined in Tanzania, Nigeria, Kenya, Madagascar, Mozambique, Namibia, Afghanistan, Pakistan, and Sri Lanka, and Malawi.[5]
Some tourmaline gems, especially pink to red colored stones, are altered by irradiation to improve their color. Irradiation is almost impossible to detect in tourmalines, and does not impact the value. Heavily-included tourmalines, such as rubellite and Brazilian paraiba are sometimes clarity enhanced, which must be disclosed to the buyer. A clarity-enhanced tourmaline (especially paraiba) is worth much less than a non-treated gem。
