Triumphant horns blare while citizens ooh and aah at the plunder of conquered lands. That captive king is led by in handcuffs. And then Marcus Aurelius, the Eisenhower of the day, rolls through on his four-horse chariot, rose petals strewing in his path.凯旋的将军们带着满载战利品的推车沿着街道行进。市民们赞叹着来自征地的掠夺物,同时胜利的号角响起。那受俘的国王铐着手铐被带进来。接着马可·奥理略(罗马皇帝),等同于那时的艾森豪总统,驾着他的四马战车通过,玫瑰花瓣洒落在他行经的道路上。The Dying Gaul is a Roman copy of a Greek original made in the third century B.C. It was used as propaganda, part of the monument celebrating a victory over the barbarians. You can ponder scenes of Romans slaughtering barbarians, and look into the eyes of now-forgotten emperors.《垂死的高卢人》是座造于西元前三世纪的希腊原作的罗马复制品。它被用来作宣传用途,纪念碑的一部分颂扬一场击败野蛮人的胜利。你可以遥想罗马人屠杀野蛮人的场景,并且望进现已被遗忘的皇帝们的双眼。And the museum also shows a more peaceful and intimate side of Roman life. Heres a boy quietly pulling a thorn from his foot.物馆也展示出罗马生活较宁静且怡人的一面。这儿是个男孩静静地从他脚上挑出一根刺。At first glance, these look like paintings. But a closer look shows they are micro-mosaics made of thousands of tiny fragments. This one hung in Emperor Hadrians villa.乍看之下,这些看起来像画。但再靠近点会看见它们是由数千个小碎片组成的马赛克拼贴画。这一幅作品曾挂在哈得良大帝的别墅内。The Capotaline Venus, another Roman copy of a Greek original, is one of the truest represantations of the concept of feminine beauty from ancient times.卡比托利版维纳斯,另一件仿希腊原作的罗马复制品,是最合乎古代女性美感观念的代表作之一。And this statue, called the Drunken Faun, is a playful reminder that a th of ancient Rome that survives today is a fondness for good food and fine wine.而这座雕像,名为《醉酒牧神》,是个有趣的提醒,提醒着这条留存至今的古罗马历史脉络,是关于对佳肴和美酒的钟爱。201508/392374

Present day engineers have目前,工程师们begun thinking about the principals of building such a ship.已开始苦心研究如何建造出这样的飞船This is what it might look like.它看上去可能是这样的It could use atomic energy它可能会用到核能or perhaps more exotic fuel such as antimatter或更高能的燃料,如反物质supplying it with enormous amounts of power,用其产生的巨大能量供给机器加速yet I think the main challenges wont be technical.但我认为,真正的挑战并非科技The first will be financial.首要难题是资金The cost of constructing an interstellar spacecraft would be huge构建这样一艘宇宙飞船耗资巨大and for the society that made it, there would be little pay back.而筹建它的社会几乎没有任何回报They would never see it again.他们永不会再见到它So constructing such a machine will因此,建造这样一台机器either be the greatest act of generosity in history或成为人类历史上最无私的奉献or will have to be funded by the travelers themselves.或只能留给探索者自己去筹资And that raises the second problem.如此一来,第二个难题又来了Even if it could travel mind numbingly fast,即使它能以让人头晕目眩的速度航行say 1,000 times faster than Voyager,比如千倍于旅行者号11,000 miles a second,即秒速11000英里a journey to the nearest star system would still take这样到达最近的星系依然需要73 years.73年Such a long trip means that at least one whole generation of humans如此长距离的航行意味着至少一代人would have to live their entire lives in space.需要在宇宙中度过他们的一生We couldnt exactly say they volunteered for the mission.而我们还不能肯定,他们是否情愿The ethics of sending a human cargo on such a voyage从伦理角度讲,把人送上这样一艘飞船 would have to be carefully considered.必须经过周密的考虑Unless we could extend human lifespans to long enough to除非我们能够延长人类的寿命make such massive journeys.来完成这项重大的使命And that I think is what we will ultimately end up doing.我想,这很可能是我们最后的解决途径The process has aly begun as I know from personal experience.据我的个人经验,这一工程已经启动My muscles no longer function,我的肌肉已经萎缩although my eyes and my brain are still working pretty well.只有眼睛和大脑还能正常运作But technology helps me to move and communicate.但现代科技让我能够移动和与人交流In the future,在未来technology will do much more than that for all of us.科技将带给我们的远不止于此201510/406510

A new report from the Centers for Disease Control and Prevention says the Zika virus does cause birth defects like microcephaly, but not in every case. 美国疾病控制和预防中心的一份新的报告表明,寨卡病毒确实会造成像小头症样的出生缺陷,但并不是每个案例都如此。Researchers have been trying to determine the link between Zika and microcephaly since the mosquito-carried virus began to sp quickly early last year, especially in Central and South America. Microcephaly is a birth defect that causes a babys head to be abnormally small.自去年这种蚊携带病毒开始迅速传播,特别在美国中部和南部地区,研究人员一直试图确认寨卡病毒与小头症的关系。小头症是一种出生缺陷,造成婴儿头部不正常的小。CDC Director Dr. Thomas Frieden said in a press release, ;There is no longer any doubt that Zika causes microcephaly.; 疾病控制中心主任托马斯士在一份新闻稿中表示,“不再有任何疑问,寨卡病毒会导致小头症。”The CDC noted ;no single piece of evidence provides conclusive proof,; but said multiple studies backed up the CDC research. 疾病预防控制中心指出,“没有据提供确凿的明,”但多项调查持疾病预防控制中心的研究。There were other theories about what was causing the rise in microcephaly cases. One report suggested pesticide-contaminated water could be to blame.还有其它理论关于引起小头症病例上升。一份报告指出,有可能是农药污染的水引起的。And some Brazilians believed that vaccines were causing Zika. 一些巴西人认为疫苗导致了寨卡。Currently, theres no cure for the Zika virus or microcephaly. 目前,对寨卡病毒或小头症没有治愈方法。But researchers who worked on an Ebola vaccine say human trials for a Zika vaccine could begin as early as this summer. 但致力于埃拉病毒疫苗的研究人员表示,人体试验寨卡疫苗最早可能在今年夏天开始。译文属。201604/437587
