For many UFO conspiracy aficionados, the phrase "Area 51" conjures up images of a secret military facility in the Nevada desert that's home for captured flying saucers. But is this true?

　　对于众多UFO爱好者，“51区”这个词通常让人想到那个位于内华达沙漠，关押有来自飞碟的神秘外星人的军事重地。

　　"Area 51: An Uncensored History of America's Top Secret Military Base," a new book by investigative reporter Annie Jacobsen, lifts the veil on this six-decade mystery and raises a more explosive possibility: Did former Soviet leader Josef Stalin recruit Josef Mengele, the Nazi "Angel of Death," to surgically alter children to look like aliens in 1947 to be part of the legendary Roswell, NM, UFO crash?

　　《51区：史料无考、高度机密的美国军事重地》，调查记者安妮?雅各布森的新书解开了这个长达六十年的未解之谜的神秘面纱，并且给出了一个更具爆炸性的解释：前苏联领导人约瑟夫?斯大林是否曾招募纳粹的“死亡天使”约瑟夫?门格勒对儿童实施外科手术，将他们改造成罗斯维尔飞碟坠毁事件中所谓的“外星人”？

　　If the story is correct, the "UFO" and its otherworldly occupants eventually found their way to Area 51 for examination.

　　如果她的推论是对的，那么关于51区、UFO以及其上的外星人这一连串问题都将得到合理解释。

　　The government has never officially confirmed that Area 51 exists. And yet, as Jacobsen learned while researching her Area 51 book, Cold War spy planes (including the U-2) were developed at the base. Through declassified documents and discussions with Area 51 personnel, Jacobsen pieced together the puzzle of what went on there. "In my reporting, I used 74 sources, 32 of whom lived and worked at Area 51 for extended periods of time," Jacobsen told AOL.
