Did you ever have a broken leg? 你曾经有过一条腿骨折吗?Or did you ever see someone else in a cast?或是你曾经看到过别人腿上裹着石膏吗?If so, you may have noticed something odd whenthe crutchescome out.如果有的话,你会发现拄着拐杖时,会有奇怪的事发生。You would think that person would be the slowest in the crowd,just hobbling along.你会认为那个拄着拐杖的人应该是人群中走得最慢的,因为他们步履蹒跚。But that is not so.但事实并非如此。Once someone becomes comfortable moving around on crutches, they can often move very quickly, even outpacing uninjured folks.当一个人习惯了用拐杖走路以后,他们就可以移动的很快,甚至超过没有受伤的人。Whats going onhere?这是为什么呢?The answer is found in the dynamics of walking. Ask yourself the following question:我们可以在走路的动力学中发现。问问你自己以下问题:who can walkfaster, a ballet dancer whose leg muscles are extremely fit, or a couch potato whose legs aresoft and flabby?谁可以走得更快?是腿部肌肉非常健壮的芭蕾舞演员,还是腿部柔软松弛,整天坐着看电视的人?Were not talking about running now, just about walking.我们不是说跑步,只是走路。The answer? Whichever one is taller.是?谁更高就走得更快。Yep. Leaving aside issues such as weak knees and just speaking in general, muscular ability doesnot determine walking speed.是的。撇开膝关节疲软不说,就一般来讲的话,肌肉的能力并不能决定走路的速度,Its the length of the leg that does it.但腿的长度可以。Little children have to run tokeep pace with a walking adult not because their muscles are weak but because their legs areshort.小孩子要跑步才能跟上大人的步伐,并不是因为他们的肌肉不够发达,而是他们的腿太短了。Now, lets think about the person with the broken leg.现在我们来看看骨折的腿。True, one leg is out of commission and theres the extra weight of the cast.的确,一条腿不能发挥作用了,并且还有额外石膏的重量。But if you watch a person on crutches walk, youll notice thatthey keep both legs together with their torso and pivot from the shoulder.但是如果你看到一个人拄着拐杖走路,你会发现他们的双腿总是与身体和肩部的点保持一致的。The body swings forward as the crutches lean back, and vice versa.当拐杖向后靠时身体就向前摆动,反之亦然。That way they canmove as if the majority of their body were two gigantic legs.这就是为什么他们可以走动,因为他们大部份的身体就像两条巨大的腿。Their stride effectively becomes thatof someone about twice their actual height.他们走路的速度可以和比他们高两倍的人相提并论。 201412/347614Do you take your vitamins everyday? Be careful.你每天都补充维他命么?小心点。Just as vitamin deficiency can make you sick, so can vitamin toxicity.就如缺乏维他命会使你生病一样,维他命中毒也会令你生病。Indeed, vitamins can be very dangerous if you take them in high quantities.事实上,如果摄入剂量太大,维他命会变得非常危险。Though vitamins A and D are the most likely to make you sick if you take too much of them, they arent the only vitamins that can be dangerous.尽管维他命A和维他命D是最有可能因为用过量导致生病的,但是它们不是仅有的两种会造成危险的维他命。All vitamins have the potential to be toxic if youingest too much of them.如果你用剂量过高,所有的维他命都有成为毒药的可能。Part of the reason why A and D put you at higher risk than Vitamin C and others has to do with the way vitamins are dissolved.用维他命A和维他命D比维他命C以及其他维他命存在更高风险的部分原因在于维他命的分解方式。Vitamin C dissolves in water.维他命C溶于水。Thus, if you take excess Vitamin C,your body can flush it out through urine.因此,如果你用了过量的维他命C,你的身体可以通过尿液将其排出体外。Vitamins A and D, however, dissolve in oils and meltedfat.而维他命A和维他命D却是溶于油和脂肪的。So, when you take too much of one of these vitamins, rather than flushing the excess out, the body stores the surplus in fat or in fatty tissues such as the liver and the brain.因此,如果你过量摄入这几种维生素的话,身体会将剩余部分存入脂肪或脂肪组织,比如肝脏和大脑,而不会排出体外。Accumulation of water in the brain, severe headaches, and birth defects are just three of the problems toxic levels of Vitamin A can cause.脑积水、严重的头痛和先天畸形仅仅是维他命A中毒会造成的众多疾病中的几种。If you keep a relatively well-balanced diet, youll most likely get the vitamins your body needs without the use of supplements.如果你保持饮食均衡,那么你也许已经摄取了身体所需的维他命,不需要补充。201412/351060

Last month, the State Board of Education did something that was right and courageous—and which I felt certain at the time was bound to be misconstrued.Board President John Austin announced they were considering a new set of voluntary polices to help make gay, lesbian, bisexual and transgender students feel safe in school.These included the suggestion that transgender students be allowed to use the bathroom in which they felt most comfortable.This wasnt a case of a bunch of out-of-touch bureaucrats imposing their dictates on the helpless population. The board couldnt if they wanted to; they dont have that kind of power.What they were proposing were voluntary guidelines.Whats more, they didnt even plan to adopt them until May. What they did was announce they were releasing their suggestions for public comment. Surprisingly, a board member told me that for a week or so, the reaction they received was largely positive.Then the national right-wing media got hold of the story, and reacted pretty much in the way sharks react to blood in the water.Fox TVs Tucker Carlson attacked the guidelines on his blog, and issued a demand for Austins emails about this issue. Tea Party activists sent out an ;action alert; advising members to attack guidelines, and the state board.This was followed by what looks like an orchestrated and well-financed campaign of postcards and luridly obscene robocalls, saying that John Austin wanted to allow male perverts to come into your little daughters bathroom at school.Republicans in the state Legislature then went after the state board, which now has a Democratic majority.Well, none of this surprises me very much, especially at the legislative level.After Flint and other excesses of the Snyder Administration, Republicans desperately need an issue if they hope to hang on to the lower house of the Legislature this year.But it would be nice if someone were to tell the truth as to what this is all about.This began when Rick Joseph, last years teacher of the year, came to the board and pleaded with them to do something to help LGBT students learn. Joseph, a middle school teacher in Birmingham, set out to become a lawyer, but went into education because he cared about closing the gap between minority and other students and helping them learn.According to statistics supplied by the state board, such students – who are more than eight percent of all Michigan students—have it worst of all. Their grades suffer. Many miss a lot of school because they feel unsafe.A really shocking 29% tried to commit suicide in the past year.Bullying goes on in high schools, some of which resemble the Lord of the Flies more than anything else; half a century ago I was called a queer and beaten up for the crime of being nonathletic and ing a lot.To make any childrens lives a living hell because of sexuality and gender identity makes no more sense than persecuting them if they are Black.The Michigan Board of Education has been trying to do its job and protect children. Sadly, there are others who see kids as only pawns to be used in their political games.Jack Lessenberry is Michigan Radios political analyst.

A new audience report from the Nielson company says that American adults spend about 10 hours and 39 minutes of each day consuming media. 尼尔森公司的一项新观众报告显示,美国成年人在媒体上每天花费约10小时39分钟。Those numbers include computers, smartphones, games, radio, and other media devices. 这些数字包括电脑、智能手机、游戏机、收音机和其他媒体设备。The report, released Monday, shows an overall increase of an hour over last year. 周一公布的报告显示,在过去一年中整体增加了一个小时。That dramatic rise is being attributed to the increased proliferation of tablets and smartphones.这引人注目的上升归因于平板电脑和智能手机使用的增加。According to the study, about 81% of U.S. adults have a smartphone.根据这项研究,大约81%的美国成年人有一部智能手机。译文属。201607/452330

There are 12 toxic hot spots in Michigan called Areas of Concern.These are places in the Great Lakes basin where pollution and development have damaged the ecosystems.The Detroit River is on this list. Before the Clean Water Act, industries on the river treated it as a dumping ground – think waste in the billions of gallons.Rose Ellison is with the Environmental Protection Agencys Great Lakes National Program Office.;In years gone by, billions and billions [of gallons] of untreated industrial and municipal waste went into the Detroit River,; she says.Over the years, a lot of people have been working to clean up the river.;Its in really good shape, but there are pockets,; Ellison says. ;No place is perfect, and its an industrial river, so there are pockets that still need attention.;She says the contaminated sediments at the bottom of the river are one of the major things they still have to tackle. At the same time, people are working to improve habitat for the creatures that live here.A big pot of federal money has given this cleanup a kick in the pants. Its called the Great Lakes Restoration Initiative.A two million dollar chunk of that money is going to a special construction project in the river near Ecorse.You have to get on a boat to see it.The boat takes us upstream of Grassy Island. Here, two barges are parked side by side and a crane operator is using a GPS-guided system to carefully drop buckets of broken limestone into the water.Theyre building a reef.Jennifer Read is with the University of Michigan Water Center.;On the bottom of the river were going to have a four acre reef,; she says. ;Its actually lots of space there for fish to lay eggs and for the eggs to be incubated and hatch out and protect the fry.;She says theyre making a better home for native fish. Especially the lake sturgeon. Its listed as a threatened species in Michigan.;Kids love them,; she says. ;Theyve been around since the dinosaurs unchanged, and I think thats what makes them really exciting. Theyre big fish — they can be up to 6 feet. Theyre huge.;She says the reefs also meant to help out whitefish and walleye.And that makes Terry Pickard pretty happy. Hes with the Downriver Walleye Federation.;I get to see where this reef really is, so if I come in the springtime I know where its at,; he says, laughing. ;All the other guys have to find it now!;He says he gets out here as soon as he can, every year.;Since the early 90s, I started fishing out here,; Pickard says. ;Jigging in the springtime, well be out here fishing when the ice flows are coming through, and youre dodging icebergs. You know, it feels like a mini Titanic out here. Its cold, you have ice on the eyes of your fishing rod, on your line, and youre like, Why am I out here? and then you get a walleye on — and its like, This is why Im here.;He says hed like to see more of these projects go in around the Great Lakes.And in fact, there are aly three reefs in the St. Clair River, and two reefs in the Detroit River, with another two planned for the future. The people who are doing this work say it looks simple, dropping some rocks in the river. But its a massive effort — 15 years in the making — with federal and state agencies and universities involved.Jim Boase is with the U.S. Fish and Wildlife Service. Boase is a biologist, but he says he feels more like a salesperson telling people why they should care about cleaning up the Detroit River.;I get this question from the public a lot: the So what? Why are you doing this?; he says.He says he has two main points to his sales pitch for the river.;Some of the best fishing in the world is right here,; Boase says. ;Theres also the migratory fly-way for ducks for people that hunt.;And he says when you create these opportunities it can have a ripple effect on the economy.;Folks that come here to fish, they stop at the bar possibly to celebrate the great things that theyre catching out here in the waterways,; Boase says. ;So the guy that owns the restaurant along Jefferson Avenue, its important to him, I betcha.;The reef projects are part of a bigger effort to improve fish and wildlife habitat. So that one day, the Detroit River can get off the toxic hot spot list.201510/404818

Japanese investment in South-East Asia东南亚地区的东瀛资本Outward bound向外拓展A weak domestic economy is spurring Japanese firms to expand abroad羸弱的国内经济形势鞭策着日本公司向海外进军IT IS not every day that the opening of a shopping centre attracts a prime minister, but then Aeon Mall in Phnom Penh is not any old shopping centre. The Japanese-built complex is Cambodias biggest, complete with an ice rink, television studio and bowling alley. For Hun Sen, the attending prime minister, it is a symbol of Japanese investment. Governments across South-East Asia are courting Japanese firms, and a torrent of yen is surging their way.一间购物商场的开张剪吸引了国家首相的参与,这可不是天天都能看到的事情。不过,位于金边市的永旺购物中心也不是一般的旧式商城。这间由日本人建造的综合体是柬埔寨国内规模最大的商城,其中还配备了溜冰场、电视演播室和保龄球场。对于这位参加了剪活动的首相洪森来说,永旺购物中心正是日本投资的象征。目前,东南亚各国政府都在极力讨好日本公司,而与此同时,后者也用大量的日元为自身铺出了一条康庄大道。Japanese investment in the region doubled to 2.3 trillion yen (24 billion) last year, the latest in a series of sizeable increases. Part of that is mergers and acquisitions by Japanese firms, which have skimped on investment at home and so have a cash hoard of some 229 trillion. SoftBank, a Japanese mobile carrier, just led a 100m investment in Tokopedia, an Indonesian e-commerce firm; Toshiba, a conglomerate, has pledged to invest 1 billion in South-East Asia over five years. A year ago Mitsubishi UFJ Financial Group, Japans biggest bank, spent 536 billion to buy 72% of Thailands Bank of Ayudhya.日本人在东南亚地区的投资额连续大幅上涨,最新数据显示,去年该指标翻了一番,达到了2万3000亿日元(约240亿美元)。其中部分数额是由日本公司所主导的企业吸收与合并产生的。这些公司省下了在日本国内的投资款项,从而囤积了约有229万亿日元的现金储备。在日本移动通讯产业巨头软银(SoftBank)的领投下,印尼电商平台Tokopedia刚获得了1亿美元的融资;在过去的五年时间里,东芝集团(Toshiba)已经在东南亚许下了10亿美元的投资承诺。而在一年前,三菱UFJ金融集团(Mitsubishi UFJ Financial Group,日本规模最大的)出资5360亿日元,购买了泰国大城(Bank of Ayudhya)72%的股权。During the first wave of Japanese investment, in the 1980s and 1990s, money poured into Thailand, Malaysia and Singapore, building up their automotive and electronics sectors. That flow largely ceased after the Asian financial crisis of 1997-98, when Japanese firms began to focus on Chinas vast, cheap labour force.在第一次日本投资潮期间,即20世纪的80年代和90年代,资本涌入泰国、马来西亚和新加坡,构建了当地的汽车和电子产业。而大部分资金流在97至98年的亚洲金融危机后便随之终止。从那时开始,日本公司便将发展焦点转移到了中土王国,后者所拥有的劳动力不仅规模庞大,其价格也十分低廉。Yet with labour costs now steadily rising in China, and political tensions between Japan and China continuing to flare, South-East Asia looks attractive again. Japanese investment in China fell by nearly two-fifths last year, even as it grew in places like Cambodia. Although China is still Japans biggest trading partner, Japanese firms invested nearly three times more in South-East Asia last year. For South-East Asian countries, too, Japan is an important hedge against China.然而,随着现在中土王国劳动力成本节节攀升,同时中日两国之间政治局势也在持续紧张,东南亚地区便再次成了令人垂涎三尺的宝地。即便是在柬埔寨之类的地区,去年的日本投资额也呈现出增长,但日方在华投资总额却下降了约五分之二。虽然中土王国目前还是日本最大的贸易伙伴,但去年日本企业在东南亚地区的投资总额比在中土王国的数额高出了接近三倍。对于东南亚各国来说,与日本方面合作同样也是一个抗衡中土王国的重要手段。But the embrace of South-East Asia is not without its critics. Some worry that the headlong rush to the region by Japanese banks, in particular, may prove short-lived. In 2013 the Bank of Japan began buying bonds with newly created money (quantitative easing), as part of a plan by Shinzo Abe, the prime minister, to banish deflation and boost growth. The central banks purchases left Japanese banks with lots of cash: they keep roughly 15% of their assets as excess reserves at the BoJ, earning minuscule returns. Since demand for loans in Japan is still subdued, they are hunting for borrowers abroad. Lending by Japanese banks to the rest of Asia, including China, has grown quickly since the end of 2012 and stood at 465 billion in June. But if Japans monetary policy changes, such flows could reverse.但是,一头扎进东南亚地区的策略也惹来了批评声音。部分人士担心,日本不顾一切地涌入该地区的行为,尤其是对于业来说,或许只是昙花一现。2013年,日本央行开始用新印的钞票购买债券(量化宽松),而这正是日本首相安倍晋三(Shinzo Abe)消除通缩和刺激经济增长计划当中的一部分。央行的债券购入使得日本各大拥有大量现钞:他们只预留了15%左右的资产作为央行所需要的超额准备金,而这是只能获得极低回报的那部分。由于日本的贷款需求依旧疲弱,们便把目光投向了海外市场。包括中土王国在内,日本对日本以外亚洲国家的放贷量迅速增长。本次增长自2012年底开始,到了本年6月贷款总额已经达到了4650亿美元。但如果日本的货币政策变更,情况也会随之逆转。Meanwhile, Japans government wants local firms to invest more at home. Quantitative easing has weakened the yen, making it more attractive to do so. But Japans rapidly ageing population means the domestic market is shrinking, undermining the incentive to build new factories. For every Canon, a camera-maker, which recently said it would increase the share of its production in Japan, there are several counter-examples, such as Mitsubishi Motors, a carmaker, which is building a new factory in Indonesia. Japanese firms focus more on profits than in the past, thanks to improvements in corporate governance, notes Robert Feldman of Morgan Stanley, an investment bank; that is prompting them to look for better prospects abroad.与此同时,日本政府希望本地公司更多地在日本本土进行投资。量化宽松政策已经使得日元贬值,投资活动也显得愈发吸引人。但日本方面急速加剧的人口老龄化问题,意味着国内市场的持续缩减,阻碍着新工厂的投资建设。近期,对于每一家声明想要增加“国内制造”份额的厂商来说,例如佳能(Canon,相机制造商),都有着好几家“反例”在与之共存。比方说,三菱汽车(Mitsubishi Motors,汽车制造商)就在印度设立了新的工厂。投行根士丹利(Morgan Stanley)的Robert Feldman表示,现在的日本公司比从前更注重于利润,而这都要归功于公司治理的进步;正是出于对利润的追求,鼓动着日本公司到海外寻找商机。With more production shifting abroad, Japans exports are also suffering. Deutsche Bank estimates that outbound investment reduced Japans trade balance by as much as 16 trillion yen in 2012, by providing local substitutes for Japanese exports. That is more than Japans trade deficit that year of 7 trillion yen. Profits from abroad were not sufficient to make up for the damage to the current account. As overseas ventures accelerate, they will help tilt Japan towards a trade deficit more often, leaving its financial system more vulnerable to the fragilities built up over decades.海外生产增加的同时,日本的贸易出口也遭到了沉重打击。根据德意志(Deutsche Bank)的估计,由于其他国家本土生产的产品,可以替代日本的出口产品,2012年日本的海外投资对本国贸易逆差的增加额为16万亿日元,而这比当年7万亿日元的贸易逆差数额还要高。海外的利润并不足以补偿国内经常账户的损失。随着海外投资的加速增长,日本会因而更容易地处于贸易逆差的态势,使得本国金融系统在数十年来累计的脆弱性之下无所遁形。The risk is that Japan could become a “rentier” economy, says Martin Schulz of the Fujitsu Research Institute in Tokyo. In this scenario, Japanese firms do not make the investments in Japan that are needed to generate broad-based wage growth, and focus instead on their foreign ventures. That would leave Japan living off the “rent” from its foreign assets, rather than the fruits of domestic economic activity.东京富士通研究所(the Fujitsu Research Institute)的Martin Schulz表示,海外投资的风险,在于日本很可能由此变成了一个“食利者”经济体。在上述情况下,日本公司不再向国内的项目进行投资,但国内投资是提高国内工资水平的必要因素;日本公司会专注于旗下的外国企业。这会使得日本经济靠国外资产的“利息”来存活,不再是由国内经济活动收益来撑。That prospect does not seem to be deterring Japanese firms. Just outside Phnom Penh is a new industrial park set up to lure Japanese manufacturers such as Minibea, which makes tiny motors for mobile phones, and Ajinomoto, which makes food seasonings. There is a constant stream of new tenants; the zone is now in its third phase of development, says Hiroshi Uematsu, who oversees it. “As a private firm, you need to go somewhere,” he says.这样的前景并没有阻止日本公司前进的脚步。就在金边市,有一片新建的工业园区,以吸引日本制造商的投资。例如,美蓓亚公司(Minibea,为手机提供微型马达的厂商)以及味之素公司(Ajinomoto,调味料厂商)都在该园区设立了厂房。园区项目的监管者Hiroshi Uematsu表示,现在不断地有新成员加入进来,而园区的第三期建设也在进程当中。他提到:“只要是一家私人企业,就需要走出国门去开拓新的领地。” 译者:颜士竣 译文属译生译世 /201411/340598

But a rival dynasty stood in the way of Plantagenet ambition. 但对手挡在了金雀花王朝的野心扩张之路上。The Princes of Gwynedd had ruled here for centuries. 格温内思郡的首领们已经统治近几个世纪。Llywelyn ap Gruffydd, and his younger brother Dyfed, were the latest in a long line of warrior leaders who held a crown said to be King Arthurs. 罗埃林格鲁菲和他的年轻弟弟德维是最近举起反对旗帜的勇士。Edwards father Henry, recognised Llywelyn as Prince of Wales, as long as he paid homage to the English crown. 爱德华的父亲亨利曾将罗埃林封为威尔士亲王,只要他对英国皇室效忠。But when Edward took the throne, Llywelyn refused to pay homage. 但当爱德华继承王位, 罗埃林却拒绝效忠。Edward declared Llywelyn a rebel and a disturber of the peace. 于是爱德华宣布罗埃林为叛军并且扰乱和平。And in 1277 set off westward from Chester at the head of a powerful army of 800 knights, crossbow men from Gascony and 16,000 infantry. 而在1277年一800名骑士组成的大军从西切斯特浩浩荡荡出发,还有来自加斯科尼的弩手,以及16000名步兵。201410/335446
