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 backgroundHuman 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 geographyBesides 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 developmentHuman 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.（中文对照）楼兰的消失： 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。

如何消除食品安全的威胁
（模拟联合国大会英文演讲稿）
2Food security under threat: global response needed Climate change and commodity speculation are among the main factors threatening food security inside and outside the EU, according to a European Parliament resolution adopted on Thursday. MEPs call for urgent measures to combat food price manipulation and ensure that food production is maintained in the EU. Droughts, floods, fires and storms, on a greater scale than in the past, are reducing agricultural capacity all over the world, says the resolution. Soil and water management must be improved to prevent loss of farmland, and the Commission should monitor national climate change mitigation measures, believe MEPs. Tackling speculationMEPs criticise speculation in food commodities, agricultural raw materials and energy markets, all of which puts food security at risk. The G20 is urged to work for the convergence of market regulations by involving countries that are not part of the G20 in the fight against food price manipulation.Parliament asks the Commission to consider giving the new European Security and Markets Authority more power to prevent abuses in commodity markets. Dealing in food commodities should be limited to investors who have a genuine link with agricultural markets, MEPs believe.In addition, MEPs call on national governments not to impose curbs on exports, as these provoke greater uncertainty in the markets and disrupt world markets, and therefore have the potential to drive prices up further at global level. Helping EU farmersTo guarantee food security in the EU, a strong Common Agricultural Policy is needed, says the resolution. Declining farm incomes, caused by higher production costs to meet health, environmental and animal welfare standards, need to be urgently addressed to ensure there are farmers in the EU in the future. Market intervention tools, such as intervention and strategic stocks, must be part of the policy, says Parliament.Support for farmers in developing countriesSince agriculture is a key economic sector in the developing world, MEPs call for a larger proportion of the financial aid for this sector to be used to support more effective and sustainable farming practices. They add that land ownership should be promoted to reduce poverty and increase food security.The resolution was approved by show of hands. 3New threat to global food security as phosphate supplies become increasingly scarceA new report from the Soil Association reveals that supplies of phosphate rock are running out faster than previously thought and that declining supplies and higher prices of phosphate are a new threat to global food security. ‘A rock and a hard place: Peak phosphorus and the threat to our food security’ highlights the urgent need for farming to become less reliant on phosphate rock-based fertiliser. [1]Intensive agriculture is totally dependent on phosphate for the fertility needed to grow crops and grass. Worldwide 158 million tonnes of phosphate rock is mined every year, but the supply is finite. Recent analysis suggests that we may hit ‘peak’ phosphate as early as 2033, after which supplies will become increasingly scarce and more expensive. [2]This critical issue is missing from the global policy agenda - we are completely unprepared to deal with the shortages in phosphorus inputs, the drop in production and the hike in food prices that will follow. Without fertilisation from phosphorus it has been estimated that wheat yields could more then halve in coming decades, falling from nine tonnes a hectare to four tonnes a hectare. The current price of phosphate rock is approximately twice that of 2006. When demand for phosphate fertiliser outstripped supply in 2007\\\/08, the price of rock phosphate rose 800%.In Europe we are dependent on imports of rock phosphate, having no deposits of our own, but the geographical concentration of reserves adds further uncertainty to the future security of our sources. In 2009, 158 million metric tonnes of phosphaterock was mined worldwide. 67% of this resource was mined in just three countries - China (35%), the USA (17%) and Morocco and Western Sahara (15%). China has now restricted, and the USA has stopped, exports of phosphate. [3]Author of the report, Dr. Isobel Tomlinson, said: A radical rethink of how we farm, what we eat and how we deal with human excreta, so that adequate phosphorus levels can be maintained without reliance on mined phosphate, is crucial for ensuring our future food supplies.‘A rock and a hard place’ sets out the actions needed to close the loop on the phosphorus cycle. These include:Changing how we farmDifferent farming systems vary enormously in their reliance on mined phosphate. Organic farms are more resilient to the coming phosphorus rock ‘shock’, as it can only be used as a supplement to nutrient recycling (including crop rotations, green manures, and composting), and not as a replacement. Organic crops generally have a lower fertiliser requirement than non-organic crops, with a greater capacity to scavenge for nutrients through denser and deeper root systems.Changing what we eatEating less meat can reduce the demand for mined phosphate. This is because vegetable-based production is more efficient in its use of phosphorus then livestock production. Although different types of meat have different levels of mined phosphate demand depending on the farming system used to produce them. Meat from livestock grazed on grassland that has not been fertilised with artificial fertilisers, will perform much better than meat from livestock grazed on fields that have been, or livestock fed on grain grown using artificial fertilisers.Changing how we deal with human exretaThe report recommends a radical change in the way we treat human exreta and the need to abandon our current ‘flush-and-forget’ toilet systems in favour of Ecological Sanitation. The report also calls for a change to EU organic regulations to allow the use of human sewage – rich in ‘natural’ phosphate - on agricultural land to ensure phosphate levels are maintained. Globally only 10% of human waste is returned to agricultural soils. Urine alone contains more than 50% of the phosphorus excreted by humans.
中国受到的耻辱演讲稿
尊老师，亲爱的同学，大
今天，我演讲的题目是：“勿忘国振兴中华”。
中个历史悠久、美丽富饶的国家，有着自强不息的人民、奔腾的长江、咆哮的黄河
我热爱我的祖国，我为我是一个中国人而感到自豪
然而，中国的近代史却是一部中国人民饱受辛酸、欺凌与屈辱的历史。
1840年，中英鸦片战争中方失败，清政府将香港割让给英国，并租出新界99年，签订了第一个丧权辱国的《南京条约》，并赔偿英国2100万银元；1860年，清政府再次与英法两国鉴订《北京条约》；1895年中日甲午战争中方失败，中日签订《马关条约》；1937年日本侵华。
这些战争中，中国几乎没有一次胜利的。
同学们，这多么值得我们深思啊
在震惊中外的“南京大屠杀”事件中，日军在不到一星期的时间里残忍地杀害了三十多万手无寸铁的老百姓
三十多万啊
同学们，这个数字多么触目惊心啊
这些人中，有的被当作活靶子练习射击；有的被活埋；有的被生生地推入长江；有的成为细菌实验的牺牲品；他们连未满月的婴儿都不肯放过
这场惨绝人寰的大屠杀，给中国人民带来了永远的伤痛。
中国人民不会忘记，八国联军火烧了圆明园。
我们刚学完了《圆明园的毁灭》这一课，大家也搜集到了很多资料，不过，我还是再给大家详细地讲一下：当时咸丰皇帝逃到了热河，圆明园内空无一人，英法联军大摇大摆地从正门进入圆明园，他们带着工匠，把衣柜上、桌子上镶着的宝石、金边砍下来，放到麻袋里；有的人浑身挂满了金银珠宝。
他们把圆明园内凡是能拿走的统统掠走，拿不动的就用牲口搬运，实在运不走的就任意破坏。
最可恶的是他们为了销毁罪证，竟然丧心病狂的放火烧毁了圆明园。
我国这一艺术的瑰宝、建筑艺术的精华，这座世界上最辉煌壮丽的建筑顷刻间变成一片焦土和瓦砾，给我们留下的只是无尽的遗憾与愤怒。
而一些见利忘义的中国人竟充当了这些强盗的走狗
给英法联军带路的，正是清代大诗人龚自珍的儿子
多么令人心痛啊

“起来，不愿做奴录的人们，中华民族到了最危险的时候……”“平津危机!华北危机
中华民族危机
”日本帝国主义的铁蹄踩踏着中华的躯体，民族危机之时，1935年12月9日，北平数千名学生，走上街头，游行示威。
一时旗帜如海，标语成林。
“打倒日本帝国主义

我的中国心 当我看见一个个海外赤子思念家乡而抱头痛哭，我的心如刀割般疼痛。
当我看见一个个为祖国而牺牲的烈士，我的心如刀割般疼痛。
当我看见...... 这些人都是为了中华的强盛，为了中华的富有，为了人民的利益。
司马过说过“常思奋不顾身，而殉国家之急。
”有一些的人不知道珍惜现在眼前的一切去犯法，比如杀人，放火，诈骗，打劫，而做上了牢，受了应有的惩罚。
没有国家这个大家庭就没有个人的家庭,没有祖国的强大和和平，就没有社会的安定，个人的幸福。
没有个人也就不存在国家，没有社会的安定，没有个人的幸福也没有国家的强大和和平。
国家要考虑和实现社会、个人的利益，社会、个人也要实现国家的利益，国家、社会、个人和谐才会有国家的强大。
我爱中国，我爱我们的中华。
所以，让我们为中华之崛起而读书，为中华之富强而读书
