科学家曾对蜜蜂离奇死亡或消失的原因进行多番推论,包括全球气候暖化、疾病或杀虫药等。科学家和业界称这个蜜蜂消失现象为"蜂群衰竭失调"(Colony Collapse Disorder,简称CCD)。爱因斯坦的"蜜蜂预言"真是所言不假,他曾经说过"没有蜜蜂,就没有授粉,就没有植物,就没有动物,就没有人类。"蜜蜂在大自然食物链中扮演非常重要的角色,依靠蜜蜂传播花粉的行业。在美国,每年经蜜蜂授粉而生产的水果、蔬菜及核果种子总值数以百亿美元计。现时大量蜜蜂失踪或死亡,也将威胁全球农作物收成。Honey bees add billions of dollars in value to around one hundred thirty crops in the ed States. But since the nineteen eighties, researchers have been concerned about the health of these valuable pollinators.Worries grew after the winter of two thousand six. Some pollination services reported losses of anywhere from thirty to ninety percent of their hives. The beekeepers did not find dead adult bees as they often do after winter. Instead, the bees were gone. Experts gave a name to this mysterious situation: colony collapse disorder. A report in Agricultural Research magazine, from the Department of Agriculture, takes a fresh look at C.C.D. It says the disorder is truly a serious problem. But it says there were enough honey bees to provide all the agricultural pollination needed last year.Still, beekeepers reported losing about thirty-five percent of their hives in the fall and winter of two thousand seven. It two thousand six, it was thirty-one percent.The ed States has almost two and one-half million managed beehives. Experts from the Agriculture Department and the Apiary Inspectors of America did a study involving about one-fifth of them.One finding was that beekeepers who found no dead adult bees were more likely to have the most severe losses. Also, a virus called I.A.P.V., for Israeli acute paralysis virus, was present in almost half the colonies studied. But researchers say they do not know if this virus causes a colony to collapse. They say the lack of affected bees to examine makes it difficult to know exactly what the new disorder is. Losses in honey bee populations can result from a number of causes. A big problem, for example, is the varroa mite, a deadly parasite. And experts keep looking for other answers for the current situation.Scientists at the University of Virginia recently reported that air pollution may prevent bees from finding flowers to pollinate. They think ozone in the air is keeping bees and other pollinators from smelling the flowers. Bees feed on nectar and pollen from flowers. Jose Fuentes and his team at Virginia studied how far the scent of flowers travels with the wind. Before the eighteen hundreds, they say, it was more than one thousand two hundred meters. Now, they say, the scent can travel only about three hundred meters at best. Their study is in the journal Atmospheric Environment.03/65616赣州小腿吸脂术多少钱赣州整形美容医院激光祛斑多少钱U.S. President Barack Obama is urging Russians to work with the ed States to tackle the big security and economic problems of our time. In a speech to graduates of an economics school, Mr. Obama made the case for better relations.美国总统奥巴马呼吁俄罗斯民众和美国一道,携手应对我们这个时代安全和经济领域的挑战。奥巴马总统利用对俄罗斯一所经济院校毕业生发表演讲的集会,阐述了美俄两国改善关系的重要性。The president began his day in Moscow by wrapping up talks with Russian leaders.当地时间星期二,奥巴马总统首先完成了与俄罗斯领导人的会晤。He met for the first time with Russian Prime Minister - and former President - Vladimir Putin who many analysts consider the most powerful man in the country.他和俄罗斯现任总理、前总统普京首次举行了面对面的会谈。很多分析人士认为,普京目前仍然是俄罗斯最有权势的人物。Their words were cordial. Their tone was polite.会晤期间,气氛良好,言辞也彬彬有礼。"We may not end up agreeing on everything, but I think that we can have a tone of mutual respect and consultation that will serve both the American people and the Russian people well," said Mr. Obama.奥巴马说:“或许我们做不到在所有问题上都达成一致,但是我们可以采取相互尊重、互相协商的态度,我认为这对美国人民和俄罗斯人民都有好处。”A few hours later, the president shifted focus and took his case for better relations directly to the Russian people.几个小时之后,奥巴马总统把焦点直接转向了俄罗斯民众,再次阐述了改善两国关系的重要性。The venue was a graduation ceremony for the New Economic School, which was established in Moscow, after the fall of the Soviet Union, by Americans and Russians eager to provide training in free market theory.奥巴马总统一行抵达了位于莫斯科的新经济学院。这是继前苏联瓦解之后由美国和俄罗斯合建的,目的是提供自由市场经济理论的培训。Mr. Obama told the graduates that much has changed in the last 20 years. And, he talked about at length about just how the ed States sees the future of relations with its former Cold War adversary.奥巴马对该校的毕业生说,过去20年里,世界格局出现了很大的变化。他阐述了美方如何看待与俄罗斯这个冷战时期的对手今后的关系。"To begin with, let me be clear: America wants a strong, peaceful and prosperous Russia," he said. "This belief is rooted in our respect for the Russian people and a shared history between our nations that goes beyond competition."他说:“首先,我要说明的一点是,美国希望看到俄罗斯强大、和平、繁荣。这一信念源于我们对俄罗斯人民的尊重、源于我们两国之间超越竞争关系的历史上的往来。”He said the old Cold War assumption that America and Russia can only exist as antagonists who compete for spheres of influence is wrong.奥巴马说,冷战期间那种思维,即美苏两国只能作为扩大势力范围的竞争对手,是错误的。"That is why I have called for a "reset" in relations between the ed States and Russia. This must be more than a fresh start between the Kremlin and the White House - (al)though that is important and I have had excellent discussions with both your president and prime minister," said President Obama. "It must be a sustained effort among the American and Russian people to identify mutual interests and to expand dialogue and cooperation that can pave the way to progress."他说:“这就是为什么我希望美国和俄罗斯之间的关系能够进入一个崭新的局面。要做到这一点,不是说两国政府之间从头开始就足够了,虽然这也很重要,而且我和贵国总统和总理之间也举行了非常良好的会晤;但是,美国人民和俄罗斯人民之间也必须要长期努力,着眼于共同利益,扩大对话和合作,为两国关系的改善打下基础。”But the president made clear that, in his search for common ground, he is not going to set aside principles that he thinks are important.与此同时,奥巴马总统明确表示,在寻求共同点的同时,他不会将重要的原则和理念弃置不顾。He talked about human rights and matters of national sovereignty - issues that have created friction with Moscow in the past.他在讲话中谈到了人权问题以及一个国家的主权问题,这些都是让美国和俄罗斯之间产生过擦的话题和领域。"Just as all states should have the right to choose their leaders, states must have the right to borders that are secure and to their own foreign policies. That is true for Russia, just as it is true for the ed States," he said. "Any system that cedes those rights will lead to anarchy. That is why this principle must apply to all nations - including Georgia and Ukraine."他说:“就如所有国家的人民都应该有权选举他们的领导人一样,所有国家都应该有权保护边界的安全,实施自主的外交政策;对于俄罗斯、对美国来说,都是一样。一个不允许所有国家实施上述主权的体系必将导致国际局势的混乱。上述原则涵盖世界上所有的国家,包括格鲁吉亚和乌克兰。”Russia is vehemently opposed to the notion of NATO membership for the two former Soviet bloc countries. President Obama says he does not seek to impose a security arrangement on any nation. He noted Ukraine and Georgia must still clear many hurdles to be eligible for alliance membership. And, he stressed once again that NATO seeks collaboration with Russia, not confrontation.俄罗斯方面对格鲁吉亚和乌克兰这两个前苏联集团成员国希望加入北大西洋公约组织(北约)的诉求表示强烈反对。奥巴马总统说,他并不希望把某个安全框架强加给任何一个国家。他并且指出,乌克兰和格鲁吉亚还需要扫清很多障碍才有资格加入北约。他再次强调说,北约组织希望与俄罗斯合作,而不是对抗。 07/76957Obama Prepares for European Trip奥巴马总统为欧洲之行作准备  U.S. President Barack Obama will leave Washington early Tuesday morning on his first overseas trip since taking office. He will attend a global economic summit in London and a meeting of NATO leaders on the French-German border. 美国总统奥巴马星期二早上将离开华盛顿,开始他就任后的第一次海外之行。奥巴马将参加在伦敦举行的全球经济首脑会议以及在法国和德国边境举行的北约领导人会议。For the first time, Barack Obama will officially represent the ed States on the world stage. 奥巴马将第一次正式在世界舞台上代表美国。He will visit five countries in eight days, take part in three summits, hold numerous bilateral meetings, deliver a major speech on arms proliferation and open a dialogue with young people on the Internet. 在八天的行程中,他将访问五个国家,参加三个首脑会议,举行多个双边会谈。他将发表有关武器扩散问题的重要讲话,还将在互联网上与年轻人进行交流。His first stop is London for a summit on the international economic crisis held under the auspices of the G20 - a grouping of 20 of the biggest leading and emerging economies. 伦敦将是他出访的第一站。在那里,他将参加由20国集团主办的有关国际金融危机的首脑会议。20国集团由世界几个最大经济体和一些新兴经济体组成。All agree that action must be taken. But there are differences over the right mix of government stimulus spending and financial system reforms. 与会各国都同意必须采取行动,但是,各国在有关如何正确协调政府刺激开计划以及改革金融体系的关系上仍然存在分歧。President Obama was expected to push for more spending, similar to action he has aly taken to try to boost the U.S. economy. But White House spokesman Robert Gibbs says the president will not dictate specific spending targets. 预计,奥巴马总统会强调增加政府开,与他在美国采取的刺激经济的措施类似。但是,白宫发言人吉布斯说,总统不会强求各方提出具体的开数目。"The president and America are going to listen in London, as well as to lead," Gibbs said. “总统和美国在伦敦会议上担负领导责任的同时,也会倾听各方意见。”Reginald Dale is an analyst with the Center for Strategic and International Studies in Washington. 华盛顿战略与国际问题研究中心的分析人士戴尔说,奥巴马曾承诺美国将采取全新的领导方法,伦敦是他展示新领导能力的好机会。He says the president, who has promised new U.S. leadership, will have an opportunity to deliver in London."This is the chance - if Obama wants to restore world leadership - here is the opportunity being handed to him on a silver plate," Dale said. "And if he wants to show he is a world leader, he has to grasp that opportunity and do so." “这是一次机会,如果奥巴马想恢复世界领导地位,这是一个绝好的机会。如果他希望展示他是世界领导人,他就得抓住这个机会,表现出来。”Mr. Obama will also meet privately in London with the leaders of Russia, China, India, Saudi Arabia and South Korea. 奥巴马在伦敦时,还将私下会晤来自俄罗斯、中国、印度、沙特阿拉伯以及韩国的领导人。The president has talked about his desire to ease tensions between the ed States and Russia. And his initial one-on-one session with Russian President Dmitri Medvedev -- coming just days before the NATO summit -- will be watched closely. 奥巴马曾经表示,他希望缓解美国和俄罗斯之间的紧张关系。他提议与俄罗斯总统梅德韦杰夫面对面的会谈。这发生在北约峰会几天前,因此双方的会晤将受到密切关注。NATO talks will focus on the war in Afghanistan. And at this summit, President Obama's public popularity in Europe could collide with the reality that few support sending more troops into combat. 北约峰会的主要议题是阿富汗战争。尽管奥巴马总统在欧洲民众中很受欢迎,但是,在峰会期间,他可能会碰到这样的现实,那就是,很少有人持派出更多的部队投入战争。John Glenn, Foreign Policy Director for the German Marshall Fund of the ed States, says the Obama administration will likely ask the Europeans for more military trainers and civilian personnel. 设在美国的德国马歇尔基金会外交政策主任格伦说,奥巴马政府很有可能要求欧洲提供更多的军事训练人员以及非军方人员。"They are reluctant to send more troops and put them in harms' way. However, there are signs they are willing to do those other non-combat missions. I think that is going to have to be the way forward for the Obama administration," Glenn said. “他们不太愿意派遣更多的部队,让部队身处险境。不过,有迹象显示,他们愿意承担一些非战斗的任务。我认为奥巴马政府可以就此迈进一步。”Mr. Obama will not make his speech on weapons proliferation at the NATO summit. Instead, he will deliver it the next day in the Czech Republic - a relatively new NATO ally and the nation that holds the rotating presidency of the European Union. 奥巴马不会在北约峰会上发表有关武器扩散的演讲,这个话题将留到第二天访问捷克共和国时进行。捷克是北约新成员,目前是欧盟轮值主席国。The president is invited to Prague for an EU summit with Czech leaders and European Union officials. While there, he is also expected to discuss American plans for a missile defense system in Europe. The Czech Republic and Poland would host components of the system, which is now under review by the Obama administration. 奥巴马受邀访问布拉格,出席在那里举行的一个欧盟首脑会议,他将与捷克和欧盟官员举行会谈。预计,他会谈到美国在欧洲部署导弹防御系统的问题。这一系统将分别部署在捷克共和国和波兰。目前,这个系统正在接受奥巴马政府的审议。Mr. Obama will end his trip on a symbolic note in Turkey - the first predominantly Muslim country to host the new U.S. president. While there, he will seek to open a dialogue with young people in the region. Aides say Mr. Obama will host a question and answer session that will be conducted, in part, on the Internet. 奥巴马访问的最后一站是土耳其,这是具有象征意义的一个举措。这是一个穆斯林人口占主导地位的国家第一次接待美国新总统。在那里,奥巴马将与该地区的年轻人展开对话。助手们说,这些对话一部分会通过互联网问答活动来进行。03/65909江西省上犹县人民医院光子嫩肤多少钱

赣州权威整形美容医院赣州宽鼻整形要哪家医院好Sydney Weapons Summit Warns of Growing Nuclear Threat一核不扩散组织警告全球核武扩散  A new non-proliferation group warns the world is on the brink of a massive increase in nuclear weapons. The global organization has spent the past two days in Sydney looking at ways to strengthen international agreements to halt the sp of nuclear arsenals. 一个新的核不扩散组织警告说,世界处于核武器大扩散的边缘。在过去两天里,这个全球组织在澳大利亚的悉尼寻求加强国际协议的途径,停止世界核武库的增长。Leaders of the new International Commission on Nuclear Non-proliferation and Disarmament say the world had been "sleepwalking" on the issue of nuclear weapons for a decade.  新成立的“核不扩散与裁军国际委员会”的领导人表示,十年来,世界一直在核武器问题上梦游。They warn that a nuclear attack would dwarf the September 11 terrorist attacks in the ed States.  他们警告说,一次核攻击将使恐怖分子对美国的911攻击相形见绌。The organization was first proposed by Australian Prime Minister Kevin Rudd after his June visit to the Japanese city of Hiroshima, which was devastated by an American atomic bomb in 1945.  澳大利亚总理陆克文今年6月访问了日本的广岛,第一次提出成立“核不扩散与裁军国际委员会”。1945年,广岛被一枚美国的原子弹摧毁。It aims to reinvigorate the global debate on the nuclear weapons before a 2010 conference that will review the Nuclear Non-Proliferation Treaty.  该委员会的宗旨是,在2010年世界各国开会重新审议核不扩散条约之前,加强国际社会就核武器问题的辩论。The co-chairman of the group, Gareth Evans, said Tuesday that tough new measures are needed to stop the sp of nuclear warheads.  “核不扩散与裁军国际委员会”的共同主席、澳大利亚前外长埃文斯星期二说,需要采取新的强硬措施,制止核弹头扩散。"The big problem with both North Korea and Iran is the demonstration that while doing what you're totally allowed to do under the Non-Proliferation Treaty, namely develop energy for peaceful purposes, you can acquire the capacity to create enriched uranium, which in turn gives you the capacity to very quickly convert that into the material for making bombs," said Evans. 埃文斯说:“北韩和伊朗的大问题是,核不扩散条约允许它们发展核能用于和平目的,同时他们获得制造浓缩铀的能力,这种能力又使它们很快把浓缩铀转变成制造核武器的材料。”North Korea has tested a nuclear device, although it is negotiating with China, Japan, South Korea, Russia and the ed States to give up its nuclear programs. Many governments, including the ed States, think Iran is trying to violate its NPT commitments by developing a nuclear weapon. Evans says that there are between 13,000 and 16,000 nuclear warheads deployed around the world.  埃文斯说,目前在全世界部署着一万三千枚到一万六千枚核弹头。The former Australian foreign minister says it is "a bit of a miracle" that a nuclear catastrophe had not occurred during the Cold War or afterward.  他说,在冷战期间和冷战以后没有发生核灾难,这是一个奇迹。Evans heads the International Commission on Nuclear Non-proliferation and Disarmament along with a former Japanese diplomat Yoriko Kawaguchi.  埃文斯和前任日本外交官川口顺子是“核不扩散与裁军国际委员会”的共同主席。The new body includes representatives from five nuclear powers - the ed States, China, Russia, Britain and France - as well as other countries, including South Africa, Indonesia and Germany.  这个机构包括五个核大国的代表。它们是美国、中国、俄罗斯、英国和法国。该机构还有来自南非、印度尼西亚和德国的代表。Two senior figures from Pakistan and India also attended the Sydney conference. Both governments have developed nuclear weapons, and neither has signed the Non-Proliferation Treaty.  来自巴基斯坦和印度的高级官员也出席了在悉尼举行的会议。这两个国家都研发了核武器,而且两国都没有签署核不扩散条约。The NPT allows nations to develop peaceful uses of nuclear energy - such as power generation, but bars the sp of nuclear weapons.200810/53610Maradona dropped as Argentina coachDiego Maradonasspellas Argentina coach came to an end on Tuesday when soccer chiefs voted unanimously not torenew his contract,the countrys AFA football association said on Tuesday.Maradonas future had been in doubt since Argentinas 4-0 loss to Germany in the World Cup quarter-finals in South Africa earlier this month.;The executive committee... has resolved unanimously not to renew the contract of Diego Armando Maradona as coach of the national team,; an AFA spokesman told a news conference after the meeting of soccer bosses.Rumours had swirled ahead of the announcement that Maradona would not continue as Argentinas coach, a position he has held since November 2008, because of a disagreement with the AFA.Maradona told local media on Sunday he wanted to stay on as coach but only if he could keep control over the choice of his assistants.His departure means Argentina need to find a new coach for the Copa America regional tournament next year.Local media said former Boca Juniors coach Carlos Bianchi, who led the team to a string of national and continental titles in twostintsbetween 1998 and 2004, was a popular favorite to replace Maradona.Other names circulating as possible successors include Estudiantes coach Alex Sabella, Independientes former coach Americo Gallego, former Argentina coach Marcelo Bielsa and ex-River Plate, Inter Milan and Argentina striker Ramon Diaz.Vocabulary:spell: a continuous course or period of work or other activity(任期,做某事或在某处工作的一段时间)renew the contract:续约stint: a period of time spent doing something(从事某项工作或活动的时间)vibe:气氛;环境背单词 — 装英语词汇201007/110117龙南县妇幼保健人民医院打溶脂针多少钱Toyota Motor Corp. says it's on track to become the world's largest automaker. CNN's Eunice Yoon reports In the race for the title of world's largest automaker, Toyota of Japan proved Tuesday it's on track to unseat US car giant General Motors.'We've posted record highs from sales to net profit in our third quarter.' In its latest quarterly earnings report, profits jumped 7% to more than .5 billion. The company sold enough Camry sedans, Prius hybrid electric cars, and other vehicles in North America to warrant the construction of new factories there.'The impressive thing about Toyota is they're expanding in multiple regions at the same time and that's giving them a lot of momentum, er, to take that number one spot.'Drivers worldwide have praised Toyota for making what they consider low maintenance, high mileage vehicles. That formula is working in North America where the automaker is now thinking of building an eighth assembly plant, a move that could help ward off political pressure. But there has been growing criticism in the US over Toyota's rising imports. One American politician from the heart of the American auto industry in Detroit says the Japanese carmaker benefits unfairly from state-run pension systems and a government that dabbles in the currency markets. The weak yen played a big part in Toyota's profits. Yet many car analysts say those remarks are unfair.'If a politician wants to come out against Toyota, he's gonna have to come out against employment and environmental technology, and that's pretty tenuous ground to be standing on.'Toyota says it's sticking by its full year forecasts and analysts say the company is on course for an eighth straight year of record earnings. Still, Toyota in Japanese tradition is staying modest.'There is a lot of talk of us becoming number one in the world. We are trying not to be too conscious of it. We want to produce cars that the market wants.'And with it looking as though the market wants more Toyota-made cars, analysts say the company will drive by GM as soon as this year.
