贵阳做全身体检要多少钱贵 阳 治 疗 妇 科 最 好 的 医 院 是 哪 里毕 节 人 流 手 术 多 少 钱 BERKELEY, Calif. — TO those of us who visit beaches only in summer, they seem as permanent a part of our natural heritage as the Rocky Mountains and the Great Lakes. But shore dwellers know differently. Beaches are the most transitory of landscapes, and sand beaches the most vulnerable of all. During big storms, especially in winter, they can simply vanish, only to magically reappear in time for the summer season.加利福尼亚伯克利——对于只在夏天去海边游玩的人来说,海滩仿佛是一种永久的自然遗产,就像落基山脉和五大湖一样。然而,住在海边的人知道,事实并非如此。海滩是最容易转瞬即逝的地貌,而沙滩又是其中最为脆弱的一种。遇到大风暴,尤其是在冬天,它们会消失,待到来年夏季将至的时候又会神奇地及时重现。It could once be said that “a beach is a place where sand stops to rest for a moment before resuming its journey to somewhere else,” as the naturalist D. W. Bennett wrote in the book “Living With the New Jersey Shore.” Sand moved along the shore and from beach to sea bottom and back again, forming shorelines and barrier islands that until recently were able to repair themselves on a regular basis, producing the illusion of permanence.物学家D·W·本内特(D. W. Bennett)在《与新泽西海滩共度时光》(Living With the New Jersey Shore)一书中写道,“海滩是沙子在继续前往别处之前停留片刻的地方。”曾几何时,的确可以这么说。沙子沿着水岸运动,从滩涂到海底再到滩涂,塑造了海岸线和堰洲岛。直到不久前,这些地貌还能经常自我修复,制造出一种永恒的假象。Today, however, 75 to 90 percent of the world’s natural sand beaches are disappearing, due partly to rising sea levels and increased storm action, but also to massive erosion caused by the human development of shores. Many low-lying barrier islands are aly submerged.然而今天,世界上75%到90%的自然沙滩正在消失。部分原因在于海平面上升和风暴活动增加,但更重要的是,人类对海滩的开发造成了大规模的侵蚀。许多地势较低的堰洲岛已经被海水淹没。Yet the extent of this global crisis is obscured because so-called beach nourishment projects attempt to hold sand in place and repair the damage by the time summer people return, creating the illusion of an eternal shore.可是,由于所谓的“人工育滩”计划,这一全球性危机的严重程度遭到了忽视。这些工程努力在夏季游客到来之前将沙子留在原处并修复损失,制造出一种海滩永在的幻象。Before next summer, endless lines of dump trucks will have filled in bare spots and restored dunes. Virginia Beach alone has been restored more than 50 times. In recent decades, East Coast barrier islands have used 23 million loads of sand, much of it mined inland and the rest dredged from coastal waters — a practice that disturbs the sea bottom, creating turbidity that kills coral beds and damages spawning grounds, which hurts inshore fisheries.下个夏天到来之前,看不到尽头的自卸车队会运来材料填补裸露的地表并修复沙丘。光是弗吉尼亚海滩,就被恢复了逾50次。近几十年里,美国东海岸的堰洲岛用掉了2300万车的沙子,其中许多采自陆地,其余则从沿海水域挖掘。挖沙的做法会干扰海床,产生不利于珊瑚礁生存并会破坏生物繁殖地的浑浊海水,从而损害近海渔业。The sand and gravel business is now growing faster than the economy as a whole. In the ed States, the market for mined sand has become a billion-dollar annual business, growing at 10 percent a year since 2008. Interior mining operations use huge machines working in open pits to dig down under the earth’s surface to get sand left behind by ancient glaciers. But as demand has risen — and the damming of rivers has held back the flow of sand from mountainous interiors — natural sources of sand have been shrinking.砂石行业的增长如今比整体经济更为迅猛。在美国,开采出来的沙子已形成了每年上十亿美元的市场规模,2008年以来的年增长率为10%。内陆采砂采用大型机械露天作业,挖开地表,以便开采出古老冰川留下的砂石。不过,随着需求的增加,以及在水上修建大坝的行为阻止了泥沙从多山的内陆地区向外的迁移,砂石自然资源一直在缩减。One might think that desert sand would be a y substitute, but its grains are finer and smoother; they don’t adhere to rougher sand grains, and tend to blow away. As a result, the desert state of Dubai brings sand for its beaches all the way from Australia.人们或许会认为,来自沙漠的沙子应当是现成的替代品。但实际上,这种沙粒更细、更光滑,不能与较为粗糙的沙粒黏合,而且容易被吹走。因此,沙漠之国迪拜需要为了本地的海滩万里迢迢从澳大利亚进口沙子。And now there is a global beach-quality sand shortage, caused by the industries that have come to rely on it. Sand is vital to the manufacturing of abrasives, glass, plastics, microchips and even toothpaste, and, most recently, to the process of hydraulic fracturing. The quality of silicate sand found in the northern Midwest has produced what is being called a “sand rush” there, more than doubling regional sand pit mining since 2009.现在出现了海滩用沙的全球性短缺,而导致这种短缺的是越来越依赖砂石的各大行业。沙子是生产磨料、玻璃、塑料、微芯片乃至牙膏的关键用料,最近还成为水力压裂工艺中不可或缺的一环。美国中西部北面发现的硅砂在当地掀起了一股“淘沙热”,使得该地区的沙坑开采活动自2009年以来翻番有余。But the greatest industrial consumer of all is the concrete industry. Sand from Port Washington on Long Island — 140 million cubic yards of it — built the tunnels and sidewalks of Manhattan from the 1880s onward. Concrete still takes 80 percent of all that mining can deliver. Apart from water and air, sand is the natural element most in demand around the world, a situation that puts the preservation of beaches and their flora and fauna in great danger. Today, a branch of Cemex, one of the world’s largest cement suppliers, is still busy on the shores of Monterey Bay in California, where its operations endanger several protected species.不过,所有工业生产中耗沙量最大的是混凝土行业。自19世纪80年代以来,来自长岛华盛顿港的砂石——1.1亿立方米——一直在为曼哈顿的通道和路面建设贡献力量。采砂业的80%产量目前依然流向了混凝土行业。除了水和空气,沙子是全球范围内需求量最大的自然产物。这一现状威胁到了对海滩和生长在其中的动植物进行保护的工作。就在当下,世界最大的水泥供应商之一西麦斯集团(Cemex)旗下的一家分公司,仍然在加州蒙特雷湾的海滩积极采砂,危及到了数种保护物种。The huge sand mining operations emerging worldwide, many of them illegal, are happening out of sight and out of mind, as far as the developed world is concerned. But in India, where the government has stepped in to limit sand mining along its shores, illegal mining operations by what is now referred to as the “sand mafia” defy these regulations. In Sierra Leone, poor villagers are encouraged to sell off their sand to illegal operations, ruining their own shores for fishing. Some Indonesian sand islands have been devastated by sand mining.全球范围内兴起的大型采砂活动中,许多都属非法行为,但它们并未进入发达国家的视野,也未被放在心上。不过在印度,政府已出手限制在海岸附近采砂,但那些已被人称为“采砂黑手党”的非法开采集团对这些监管规定视而不见。在塞拉利昂,贫困村民受到鼓励,要将沙子卖给非法企业,从而彻底破坏了当地的近海环境。一些印度尼西亚的沙岛因采砂而遭遇重创。It is time for us to understand where sand comes from and where it is going. Sand was once locked up in mountains and it took eons of erosion before it was released into rivers and made its way to the sea. As Rachel Carson wrote in 1958, “in every curving beach, in every grain of sand, there is a story of the earth.” Now those grains are sequestered yet again — often in the very concrete sea walls that contribute to beach erosion.是时候让我们了解沙子的来源和去向了。它曾被困在山上的岩石里,经过亿万年的侵蚀才得以进入山川河流,然后来到海里。正如蕾切尔·卡森(Rachel Carson)1958年写下的那样,“在每个蜿蜒的海滩,在每颗沙粒之中,都藏有大地的故事。”现在,这些沙砾却再次受困——往往就在那些助推海滩侵蚀的混凝土防波堤里。We need to stop taking sand for granted and think of it as an endangered natural resource. Glass and concrete can be recycled back into sand, but there will never be enough to meet the demand of every resort. So we need better conservation plans for shore and coastal areas. Beach replenishment — the mining and trucking and dredging of sand to meet tourist expectations — must be evaluated on a case-by-case basis, with environmental considerations taking top priority. Only this will ensure that the story of the earth will still have subsequent chapters told in grains of sand.我们不能再认为沙子取之不尽用之不竭,而是要把它当成一种稀缺的自然资源。玻璃和混凝土可以通过回收最终变回沙子,但这永远不够满足度假村的需求。因此,我们需要更好的办法来保护海滩和沿海地区。“海滩修复”项目——用采砂、运沙和挖沙的手法来满足游客的期待——必须一个一个通过评审,并让环境方面的因素成为优先考虑的对象。只有这样,才能确保大地的故事还可以在沙粒中写就后续的篇章。 /201411/340991贵阳七个月做引产多少钱

贵 阳 治 疗 卵 巢 囊 肿 的 权 威 医 院Die Organisation ;Islamischer Staat im Irak und in Syrien; (ISIS) geh#246;rt zu den radikalsten islamistischen Gruppen im Nahen Osten. Sie k#228;mpft für einen sunnitischen Gottesstaat im arabischen Raum. ISIS ging aus dem irakischen Widerstand der 2003 gegründeten Gruppe ;Tawhid und Dschihad; hervor, die sich gegen die US-Invasion im Irak wandte. Die Gruppe griff im Irak nicht nur US-Soldaten an, sondern verübte auch Selbstmordanschl#228;ge auf Schiiten und Christen im Land.伊斯兰国组织的全称是“在伊拉克及叙利亚的伊斯兰国”(ISIS),是中东地区极端伊斯兰武装中的一。他们的目标是在阿拉伯世界建立一个逊尼派神权国家。伊斯兰国的前身是2003年成立伊拉克抵抗军——“统一圣战者组织”,与入侵伊拉克的美军作战。但他们的攻击对象不仅于美军,同时也对国内的什叶派信徒及基督徒发动自杀式袭击。Erster Anführer war der für seine Grausamkeit berüchtigte Jordanier Abu Mussab Al-Sarkawi. Al-Sarkawi wurde 2006 von der US-Armee get#246;tet. Seither führen Iraker die Organisation. Seit Mai 2010 steht der Iraker Abu Bakr Al-Bagdadi an der Spitze der ISIS. Deren zweiter Name ;Islamischer Staat im Irak und der Levante; verdeutlicht den Anspruch, einen sunnitischen Gro#223;staat zwischen Mittelmeer und Euphrat zu errichten: Der Begriff Levante (;Sonnenaufgang;) bezieht sich auf das Hinterland der #246;stlichen Mittelmeerküste.该组织的第一任首领是臭名昭著的杀人狂约旦人阿布·穆萨布·阿尔·扎卡维。自从扎卡维于2006年被美军击毙后,该组织就一直由伊拉克人领导。从2010年10月起,伊拉克人阿布·伯克尔·阿尔·巴达迪成为了伊斯兰国的头号人物。这个组织的另一个名字是“在伊拉克及黎凡特的伊斯兰国”,这个名称清晰地表示他们要建立一个横跨地中海和幼发拉底河的巨大的逊尼派国家。黎凡特(日出之地)指的是地中海东岸的腹地。An Macht gewann die ISIS, als sie sich im Frühjahr 2013 in den syrischen Bürgerkrieg einmischte. Dort überwarf sie sich mit der aus syrischen Salafisten bestehenden Al-Nusra-Front, obwohl beide Gruppen damals dem Terrornetzwerk Al-Kaida nahestanden. Vor allem im Nordosten Syriens greift Isis syrisch-kurdische St#228;dte an und t#246;tet die Zivilbev#246;lkerung. Im Irak profitiert die ISIS vom Streit der von Schiiten dominierten irakischen Regierung unter Nuri Al-Maliki mit den sunnitischen Parteien des Landes.伊斯兰国与2013年初参与了叙利亚内战并赢得巨大的影响力。他们与叙利亚萨派武装“阿尔·努斯拉”阵线先合作后翻脸,尽管两者都和基地组织的恐怖网络关系密切。伊斯兰国首先在叙利亚东北部攻击库尔德人城市并屠杀平民。在伊拉克,由于马利基总理领导的什叶派政府和逊尼派政党的党争没完没了,伊斯兰国坐收渔翁之利。Durch Spenden finanziert伊斯兰国通过募捐获得资金ISIS finanziert sich vor allem durch Spenden aus den Golfstaaten Katar und Saudi-Arabien, aber auch durch Wegz#246;lle entlang der Grenzen zwischen Irak und Syrien. In den Reihen der Gruppe k#228;mpfen internationale Brigaden, darunter Muslime aus Nordafrika und den arabischen Golfstaaten sowie Konvertiten aus Europa und Nordamerika.伊斯兰国的主要经济来源是来自海湾国家卡塔尔和沙特的募捐,同时他们也在伊拉克与叙利亚边境地区收过路费。在这个组织中还有一国际部队,由来自北非和阿拉伯海湾国家的穆斯林以及归化的欧洲人和北美人组成。 /201408/324382 May Liu earns about ,500 a month as an office worker in Hong Kong, but she spends about 10 to 15 times that on luxury goods, buying everything from Prada handbags to products from US cosmetic brand Fresh.May Liu是一名在香港工作的办公室文员,每月收入约2500美元,但她在奢侈品上的花费是这一金额的10至15倍,购买的产品从普拉达(Prada)的手袋到美国馥蕾诗(Fresh)的化妆品无所不包。While Ms Liu loves shopping, she buys mostly for others in her role as a “daigou” agent – a growing breed of people who specialise in helping mainland Chinese consumers secure products from overseas.虽然May Liu喜欢购物,但她主要是作为一名“代购”帮别人买东西——作为一个人数日渐增长的群体,代购专门帮助中国内地顾客从境外购买商品。She started her daigou business a year ago as a way to earn more money, but the young mainland Chinese was soon bringing in up to ,000 a month. Ms Liu now has about 2,600 clients, who use Weibo, China’s equivalent of Twitter, and WeChat, a messaging app, to order goods.她一年前开始从事代购业务,以增加收入,但不久之后,这位来自中国内地的年轻人每月最高就可进账一万美元。May Liu现在约有2600名客户,这些客户通过微(Weibo,相当于中国的推特(Twitter))以及聊天应用微信(WeChat)来下单订购商品。“I didn’t know how much money I would make. I didn’t have any expectation of profits,” says Ms Liu, who asked to use a pseudonym. “I only knew it would be profitable.”May Liu要求使用化名。她说:“我不知道自己能赚到多少钱。我对利润没有任何预期。我只知道这一行能赚钱。”She has not given up her day job, realising that being a daigou agent, while highly profitable, can also be illegal.她没有辞去正职工作,因为她明白,代购这一行虽然利润丰厚,但可能是违法违规的。Some agents focus on ferrying goods from Hong Kong to mainland China.一些代购专门从事将商品从香港代送到中国内地的业务。But the web-based phenomenon has sp to expatriate Chinese who are help compatriots back home buy brands from cities such as Paris, London, New York, Hong Kong, Tokyo and Seoul.但这一兴起于网络的现象现已扩散到了旅居海外的中国侨胞群体,他们帮助国内同胞从巴黎、伦敦、纽约、香港、东京以及首尔等城市购买名牌商品。The daigou boom is an example of how ecommerce is rapidly transforming the Chinese retail market.代购热潮是一个明,表明电子商务正在快速改变中国零售市场的面貌。According to Chinese media, there are hundreds of thousands of people working in the daigou business. A search for the term on Alibaba’s Taobao, China’s largest online marketplace, produces more than 240,000 virtual stores and nearly 15m items from child car seats through air purifiers to pocket printers.据中国媒体报道,目前有好几十万人在从事代购业务。在阿里巴巴(Alibaba)旗下网站淘宝(Taobao)上搜索“代购”一词,会显示出超过24万个网络店铺以及近1500万种商品,从儿童汽车座椅、空气净化器到便携式打印机无所不包。淘宝是中国最大的在线交易平台。The China e-Commerce Research Centre says the daigou market grew 19-fold between 2008 and 2012 when it reached Rmb48bn, and reckons that it rose again in 2013 to Rmb74bn (bn). According to a recent study by Bain, about 60 per cent of the Chinese consumers who buy luxury goods have used daigou at some point.中国电子商务研究中心(China e-Commerce Research Centre)表示,代购市场在2008至2012年间增长了19倍,规模达到了人民币480亿元,2013年代购市场继续增长,规模达到了人民币740亿元(合120亿美元)。贝恩公司(Bain amp; Company)近期进行的一项研究显示,约有60%的中国奢侈品消费者曾经使用过代购务。The business is thriving for several reasons. Many Chinese believe the same product is better made when bought overseas because of the mainland’s uneven reputation for quality.代购行业蓬勃发展主要是由于以下几个原因。很多中国人认为,同一种产品,购自海外的质量会好一点,因为中国大陆的产品有着质量不稳定的名声。The rising strength of the renminbi, the growing purchasing power of Chinese consumers, and high-profile food safety scandals in China, have also spurred demand for safe and high-quality foreign products.人民币汇率稳步走强,中国消费者的购买力不断提升,中国食品安全丑闻引起公众关注,也都刺激了市场对安全性高、质量又好的外国产品的需求。Mo Daiqing, an analyst at the e-commerce research centre, says the main reason Chinese are turning to daigou is because of hefty import tariffs on luxury goods. China levies a 50 per cent duty on cosmetics, one of the dominant daigou categories, and that is before the imposition of the standard 17 per cent value added tax that is added to imported luxury products.中国电子商务研究中心的分析师莫岱青表示,中国消费者转向代购的主要原因是,国内对奢侈品的进口关税太高。目前中国对化妆品征收50%的关税(这是代购商品中的一大主要门类),而在此之后还要再对进口奢侈品按标准征收17%的增值税。“The same brands of milk powder, cosmetics and handbags are much cheaper in Hong Kong, the US, Japan and South Korea than in mainland China,” said Ms Mo.莫岱青表示:“同样品牌的奶粉、化妆品以及手袋,在香港、美国以及韩国买的要比在中国大陆便宜很多。”But the industry is increasingly drawing attention from customs officials in mainland China and Hong Kong, particularly with the rising numbers of so-called parallel traders who take advantage of multi-entry visas to cross the border at the southern Chinese city of Shenzhen many times a day, carrying products for resale that they do not declare at customs.但代购行业正日益受到中国内地和香港海关官员的关注,特别是人数越来越多的“水客”(parallel traders)。这类人利用一签多行政策,在中国南方城市深圳每日穿越边境多次,将所携带的未报关商品在境内转手出售。Dong Yizhi, a lawyer who specialises in ecommerce, points out that the daigou business is not illegal if the agents pay import taxes, but says that if agents pay duties the premise of the business becomes moot.专长电商领域的律师董毅智指出,如果代购人员付进口关税,那么代购业务就不是违法的;但在这种情况下,代购将失去存在的意义。“If they pay customs duties, the price disparities will be much smaller and they won’t make money,” said Mr Dong.董毅智表示:“如果代购付关税,国内外商品的差价将显著缩窄,代购就赚不了什么钱。”Chinese citizens can legally import Rmb5,000 (3) of duty-free goods for personal use each time they return to the mainland. But Shenzhen customs officers are taking a tougher line on parallel traders who cross the border back into the mainland more than once a day with goods over the value of Rmb500.中国公民从境外返回中国大陆时,每次可以依法携带价值不超过人民币5000元(合823美元)的免税商品供个人使用。但深圳海关对每天往返境内超过一次的水客采取了更加严厉的标准:每次携带的免税货品价值不得超过人民币500元。Liu Lizhen, a Shenzhen customs official, said the move was aimed at clamping down on the abuse of the multiple re-entry system.深圳海关官员刘丽珍(音译)表示,此举旨在打击滥用多次往返签机制的情况。This has become a more serious issue in Hong Kong since 2009 when it started allowing Shenzhen permanent residents to enter the former British colony without restrictions.自2009年以来,水客在香港已经成了一个愈发严重的问题。香港自2009年开始允许深圳市永久居民不限次数前往这片曾经的英属殖民地。“We once found a person who had crossed the border 26 times a day,” said Ms Liu.刘丽珍称:“我们曾经发现过一个人,他在一天之内穿越边境26次。”According to the Shenzhen customs bureau, more than 20,000 parallel traders operate at the six land border checkpoints between Hong Kong and the southern Chinese city.来自深圳海关的信息显示,在香港与深圳之间的6个陆路口岸往返的水客数量超过了两万人。Hong Kong’s immigration department said just over a thousand parallel traders were arrested last year for breaching the terms of their stay in the territory.香港入境事务处表示,去年超过1000名水客因为违反在香港境内的逗留条款而被逮捕。Despite the crackdown, May Liu, the daigou agent, says she is not worried, and still travels to Shenzhen a few times a week.虽然面临政府打压,但作为一名代购的May Liu表示自己并不担心,仍然每周数次前往深圳。“Carrying so much stuff across the border every time provides me with a lot of exercise. I don’t even have to go to the gym,” jokes Ms Liu.她开玩笑称:“每次带这么多东西穿越边境对我来说是强度很大的锻炼。我甚至都不用去健身房了。”‘Brands are much cheaper in Hong Kong, the US, Japan and South Korea than China’“名牌商品在香港、美国、日本以及韩国的售价远比在中国内地便宜。” /201402/277279贵阳哪家医院治月经不调贵 阳 女 性 打 胎 多 少 钱
