跪求有关 楼兰的消失 英文演讲稿 语法要正确，通常，最好再带上中文翻译，内容要文艺一点的
What is happiness?
Happiness is something you decide on ahead of time.
The 92-year-old, petite, well-poised and proud lady, who is fully dressed each morning by eight o'clock, with her hair fashionably coifed and makeup perfectly applied, even though she is legally blind, moved to a nursing home today.
Her husband of 70 years recently passed away, making the move necessary.
After many hours of waiting patiently in the lobby of the nursing home, she smiled sweetly when told her room was ready.
As she maneuvered her walker to the elevator, I provided a visual description of her tiny room, including the eyelet sheets that had been hung on her window. "I love it," she stated with the enthusiasm of an eight-year-old having just been presented with a new puppy.
"Mrs. Jones, you haven't seen the room .... just wait."
"That doesn't have anything to do with it," she replied. "Happiness is something you decide on ahead of time. Whether I like my room or not doesn't depend on how the furniture is arranged, it's how I arrange my mind. I already decided to love it. It's a decision I make every morning when I wake up. I have a choice; I can spend the day in bed recounting the difficulty I have with the parts of my body that no longer work, or get out of bed and be thankful for the ones that do. Each day is a gift, and as long as my eyes open I'll focus on the new day and all the happy memories I've stored away, just for this time in my life."
She went on to explain, "Old age is like a bank account, you withdraw from what you've put in. So, my advice to you would be to deposit a lot of happiness in the bank account of memories Thank you for your part in filling my Memory bank. I am still depositing."
And with a smile, she said: "Remember the five simple rules to be happy:
1. Free your heart from hatred. 2. Free your mind from worries.
3. Live simply. 4. Give more.
5. Expect less.
何为幸福？
幸福就是你能事先决定的东西。
这位娇小、优雅、骄傲的老妇人已有92岁高龄，她每天8点之前都把自己穿戴妥当，绾着时尚的发式，画着完美的妆容，即使如今她几乎已看不见东西并搬入了疗养院，这个习惯仍然雷打不动。
与她相伴七十多年的丈夫最近去世了，为此她才搬的家。
她耐心地等候在疗养院的大厅中，过了很长时间当有人来告诉她房间已经准备好的时候，她仍然面带亲切的微笑。
在她扶着助行器走向电梯时，我打量了一眼她的小屋，没放过挂在窗户上的针孔板。“我喜欢这里！”她高兴地说着，那神情就好像8岁的孩子刚得到别人赠送的一只小狗一样。
“琼斯太太，您还没看到房间……请稍等。”
“没关系，”她回答说，“幸福就是你能事先决定的东西。我是否喜欢自己的房间并不取决于家具如何摆放，而是由我的思想主宰的。我早就决定要喜欢这里了。每天早上醒来时，我都会做出这个决定。我可以选择或者在床上度日如年地反复琢磨自己身体上的残疾，或者离开床铺并对我身体上仍然健康的那部分表示感激。每天都是上天的恩赐，只要睁开双眼，我就会关注新的一天和存留在脑海中的所有幸福回忆，珍视我生命中的此时此刻。”
她接着解释说：“岁月就像一个供人存进取出的银行账户。所以，我建议你将大量的幸福都存到回忆银行的账户中。也谢谢你给我的回忆银行增添财富。我现在还在每天储存呢。
最后她笑着说：“记住这五条简单的幸福法则吧：
1.让心灵摆脱仇恨。 2.让大脑远离烦恼。
3.简单地生活。 4.付出更多。
5.期望更少。”

Loulan's disappearance:
Recently, LuoBuBo environment of scientific expedition team LuoBuBo drilling for the comprehensive system of environmental science. According to preliminary infer that sometime in the qinghai-tibet plateau, with seven to eight million years ago, the rapid uplift LuoBuBo bysouthing north migration, drying, resulting in increased gradually whole lakes dry. Such an explanation is not satisfactory, Chinese academy of sciences institute of geology and geophysics ZhouKun professor argues that, uncle LuoBuBo dry complex reasons. It is a global problem, and regional issues, besides natural causes, and human factors.
A global climate is dry, the big background
Human and neolithic in here, the Bronze Age here, then just value population prosperous period, the temperature LuoBuBo, environment. But then, after entering cooling zone, river water environment, lakes, desert expansion. At about 2000 BC, the performance of drought in north China area in loess accumulation, ice, lakes, retreat.
The disappearance of the ancient lou-lan and about in the fourth century to the han dynasty to the north (central), then it intensifies the dry periods. In fact, the dry process, not only is the ancient lou-lan and desert expansion, and successively occur in kelatongke pier, hananiah, milan, soil, and integration of khan city of wancheng etc.
Second, the qinghai-tibet plateau uplift is geography
Besides global climate change, the uplift of qinghai-tibet plateau is the most important cause of regional. In seven to eight million years ago, the rapid uplift of qinghai-tibet plateau. The uplift of northwest China's climate decisive role. LuoBuBo due to the geographical location is located in east Asia and the Pacific northwest inland, every year and the Indian Ocean warm air almost all rarely reach here.
When the global climate change, the east west began to appear the drought and desertification, gobi tendency. During this period, LuoBuBo started from the south to the north. 7 million years ago, when the lake near lake to the last drop dramatically. Because of the uneven terrain lake, the ancient great unity of LuoBuBo decomposing now, and manasseh kelatongke lake, north of lake and LuoBuBo larger.
In regional factors, there must be worthy of note, from the remote sensing data said recently, which had a big upstream of the landslide. The landslide whole blocked river channels, which was broken LuoBuBo of water. The question now is still don't know the exact time the landslide occurred in, whether it LuoBuBo dry before remains to study.
Third, LuoBuBo accelerate human development
Human activities on the LuoBuBo dry effect, more recent in late may. Waste water and trees are the key oasis can survive. Loulan city was established in kongquehe downstream of the water resources, there was a growing HuYangShu exuberant the materials for the building. When people in LuoBuBo edge loulan diameters for 10 million square meters of loulan city, they cut off many trees and reed, it will undoubtedly on environment.
In this period, human activities and the changes of water damage, make the war and the fragile worsening ecological environment. 5 the "river churchyard density, root stump" male who had felt loulan survival crisis, to pray tribe to bless his sons reproduction worship. But they cut the trees, already scarce has deteriorated to the local environment.
The final LuoBuBo dry, and in the tarim river upstream of the liberation of our development. When we in tarim river upstream of the tarim river after water diversion, bills, appear to flow downstream. This point in recent years from the Yellow River dry-up can get by. No water supplies because of LuoBuBo also began shrinking, eventually finally die.
楼兰消失的原因：
最近，中科院罗布泊环境钻探科学考察队对罗布泊进行了全面系统的环境科学考察。考察队认为：据初步推断，随着青藏高原在距今7到8万年前的快速隆升，罗布泊由南向北迁移，干旱化逐步加剧，最后导致整个湖泊干涸。这样的一个解释显然并不能让人满意，中国科学院地质与地球物理研究所的周昆叔教授则认为，罗布泊干涸的原因很复杂。这里面既是全球性的问题，也是地域性的问题，除了自然方面的原因，还有人为方面的因素。
一、全球气候旱化是大背景
新石器时代人类便涉足这里，青铜器时代这里人口繁盛，这时恰值高温期，罗布泊湖面广阔，环境适宜。但此后进入降温区后，水土环境变差，河水减少，湖泊缩减，沙漠扩大。在距今约2000年左右旱化加剧，这表现在中国北方广大地区冰进发生，黄土堆积，湖沼消亡，海退发生。
楼兰古城的消亡大约在公元前后至四世纪(中原的汉朝到北魏时期)，这时正是旱化加剧的时期。其实，在这一旱化过程中，不仅是楼兰古城消亡，而且由于沙漠扩大，先后发生尼雅、喀拉墩、米兰城、尼壤城、可汗城、统万城等的消亡。
二、青藏高原隆起是地域因素
除了全球气候的变化之外，青藏高原的隆起是地域性中最重要的原因。在距今7到8万年前，青藏高原快速隆升。这种隆起对中国西北部的气候具有决定性的作用。由于罗布泊所处的地理位置位于东亚西北内陆，每年，太平洋和印度洋的暖湿气流几乎都很少到达这里。
当全球气候发生变化时，整个东亚西部都开始出现了干旱和沙漠化、戈壁化趋势。在这期间，罗布泊开始从南向北推移。在距今7万年左右的时候，湖面急剧下降到最后接近湖底。因湖底地形的高低不平，原先巨大统一的古罗布泊分解成现在的台特玛湖、喀拉和顺湖和北面较大的罗布泊。
在地域性因素中，还有一点必须值得注意，据说从近来的遥感资料判断，孔雀河上游曾发生了一次大的滑坡事件。这次滑坡整个堵塞了孔雀河的河流通道，致使罗布泊的来水被断。现在的问题是还不知道这次滑坡的具体时间，它是否发生在罗布泊干涸之前还有待于研究。
三、人类过度开发加速罗布泊消亡
人类活动对罗布泊干涸的影响，在晚近期可以说越来越大。水源和树木是荒原上绿洲能够存活的关键。楼兰古城正建立在当时水系发达的孔雀河下游三角洲，这里曾有长势繁茂的胡杨树供其取材建设。当年楼兰人在罗布泊边筑造了10多万平方米的楼兰古城，他们砍伐掉许多树木和芦苇，这无疑会对环境产生负作用。
在这期间，人类活动的加剧以及水系的变化和战争的破坏，使原本脆弱的生态环境进一步恶化。5号小河墓地上密植的“男根树桩”说明，楼兰人当时已感到部落生存危机，只好祈求生殖崇拜来保佑其子孙繁衍下去。但他们大量砍伐本已稀少的树木，使当地已经恶化的环境雪上加霜。
罗布泊的最终干涸，则与我们解放后在塔里木河上游的过度开发有关。当年我们在塔里木河上游大量引水后，致使塔里木河河水入不敷出，下游出现断流。这一点从近年来的黄河断流就可以得到印证。罗布泊也由于没有来水补给，便开始迅速萎缩，终至最后消亡
斯文·赫定在这里发掘了大量文物，包括钱币、丝织品、粮食、陶器、36张写有汉字的纸片、120片竹简和几支毛笔……
斯文·赫定回国后，把文物交给德国的希姆莱鉴定。经鉴定，这座古城是赫赫有名的古国楼兰，整个世界震惊了，随后，许多国家的探险队随之而来…… 经历史学家和文物学家长期不懈的努力，楼兰古国神秘的面纱被撩开了一角。
1979年，新疆考古研究所组织了楼兰考古队，开始对楼兰古城古道进行调查、考察。在通向楼兰道路的孔雀河下游，考古队发现了大批的古墓。其中几座墓葬外表奇特而壮观：围绕墓穴是一层套一层共七层由细而粗的圆木，圈外又有呈放射状四面展开的列木。整个外形像一个大太阳，不由得让人产生各种神秘的联想。它的含义究竟如何，目前还是一个未解之谜。
说法一：楼兰消失于战争。公元五世纪后，楼兰王国开始衰弱，北方强国入侵，楼兰城破，后被遗弃。
说法二：楼兰衰败于干旱、缺水，生态恶化，上游河水被截断后改道，人们不得不离开楼兰。楼兰曾颁布过迄今为止发现的世界上最早的环境保护法律。
说法三：楼兰的消失与罗布泊的南北游移有关。 斯文·赫定认为，罗布泊南北游移的周期是1500年左右。3000多年前有一支欧洲人种部落生活在楼兰地区，1500多年前楼兰再次进入繁荣时代，这都和罗布泊游移有直接关系。
说法四：楼兰消失与丝绸之路北道的开辟有关。经过哈密（伊吾）、吐鲁番的丝绸之路北道开通后，经过楼兰的丝绸之路沙漠古道被废弃，楼兰也随之失去了往日的光辉。
说法五：楼兰被瘟疫疾病毁灭。一场从外地传来的瘟疫，夺去了楼兰城内十之八九居民的生命，侥幸存活的人纷纷逃离楼兰，远避他乡。
说法六：楼兰被生物入侵打败。一种从两河流域传入的蝼蛄昆虫，在楼兰没有天敌，生活在土中，能以楼兰地区的白膏泥土为生，成群结队地进入居民屋中，人们无法消灭它们，只得弃城而去。
说法七：由于佛教文化的输入而使楼兰失去了创造力和生产力，逐渐发展成为失去了生存的能力，在这种情况下，任何一件自然因素都会导致其消失。
楼兰古尸之谜
著名的“楼兰美女”出土于1980年，当时，考古学家在罗布泊铁板河发现一具保存完好的女性古尸，女性的皮肤为红褐色，还稍有弹性，面部轮廓非常明显，眼睛大而深、鼻梁高而窄、下巴尖而翘。经过图像处理后，生活在数千年前的一位美女，栩栩如生地出现在人们面前。由于这具女性古尸是在神秘的楼兰古城附近被发现的，所以就给她取名为“楼兰美女”。
在孔雀河下游的铁板河三角洲，曾发现了一片墓地，墓中出土有一具中年女性干尸，体肤指甲保存完好。她有一张瘦削的脸庞，尖尖的鼻子，深凹的眼眶、褐色的头发披肩。她身上裹一块羊皮，毛织的毯子，胸前毯边用削尖的树枝别住，下身裹一块羊皮，脚上穿一双翻皮毛制的鞋子，头上戴毡帽，帽上还插了两枝雁翎，被世人称为“楼兰美女”。经用她身上的羊皮残皮做碳14鉴定，表明是一具距今3800年的古尸。她是谁？为什么会在这荒无人烟的地方？就成为考古界的谜。
