自7月17日起，一场浩浩荡荡的联署公开信行动正在中国网民之间展开，他们有着一个共同的目标，呼吁世卫组织彻底调查美国德特里克堡生物实验室。对此，外交部发言人赵立坚在例行发布会上表示：
此次联署自7月17日发起以来，得到了中国广大民众的积极响应，不到5天就有约500万人参加。节节攀升的数字代表着中国人民的心声，表明了他们对美方一些人借溯源问题搞政治操弄的愤怒。美国本应及早调查德特里克堡，但一直没有这样做。
since the open letter was published on july 17, it has received encouraging responses from the chinese people and
1 by about 5 million people within 5 days. the increasing
2 reflects the chinese people's
3 and their anger in the political manipulation by some in the us. a probe into fort detrick is long
4, but the us has not done it yet.
德特里克堡之谜至今无解。2019年7月，美国疾控中心给德堡基地发终止函，要求其终止大部分操作。就在同月，弗吉尼亚州北部开始出现不明原因的呼吸系统疾病，威斯康星州暴发大规模“电子烟疾病”。7月底，靠近德堡的两家养老院出现一种不明原因导致肺炎的呼吸道疾病。9月，德堡所在地马里兰州报告称“电子烟疾病”患者病例数增加了一倍。即便如此，美方仍以“国家安全”为由，拒绝公布关于关闭德堡的原因。历史上，德堡也有令人不安的劣迹和污点。基地中保存着包括德国纳粹和侵华日军“731部队”在内的细菌战研究资料。美国媒体也披露，德堡至今仍存放着大量严重威胁人类安全的病毒。这些事件之间，到底有何关联？美方究竟打算何时就此公开澄清？
the mystery of fort detrick remain unexplained and
5 by suspicions. in july 2019, the us cdc issued a "cease and desist order" to halt most research at fort detrick. in the same month, there were reports on the unexplained outbreaks of respiratory disease in northern virginia and on the subsequent evali outbreaks in wisconsin. by the end of july, two
6 communities near the base experienced unexplained
7 outbreaks. in september, vaping-related lung illness cases doubled in maryland where fort detrick is based. even so, the us cdc refused to release critical information regarding the base's closure by citing "national security reasons". the fort detrick base has disturbing records and stains in history. the base has in its storage research outcomes of biological
8 from people recruited after wwii, including head of
9 germany's biological warfare lab and head of unit 731 of the imperial japanese army that waged the war of
10 against china. according to us media reports, fort detrick stores large amount of viruses that
11 threaten people's safety. what is the
12 between those incidents? when will the us make public explanations?
调查德堡是包括中国人民在内的各国人民的呼声，是美方在病毒溯源问题上必须回答的问题。面对本国近63万因疫情逝去的生命，美方应展现透明，切实采取措施彻底调查本国疫情源头，彻底调查美国抗疫不力的原因并追究责任者，彻底调查德堡及200多个美国海外生物实验基地种种疑云，给世界人民和国际社会一个交代。
investigating fort detrick is an appeal of people all over the world, including the chinese people. it is a question that the us must answer. facing the 630,000 american lives lost to the coronavirus, the us should be
13, take concrete measures to
14 investigate the origins of the virus at home, thoroughly investigate the reason of its botched response and who should be held accountable, thoroughly investigate the mysteries over fort detrick and its over 200 overseas bio-labs, and explain the truth to people across the world and the international community.
