[1]It's exactly one month since the last reported case①. But [2] it is vital② not to take any chances③. So, [3]20 health care workers from almost as many countries ，comrades④ in arms, raise virtual⑤ glasses to each other. [1]本句为“It is＋一段时间＋since...”结构，意为“自从……已有……时间了”。 [2]此处it作形式主语，真正的主语是“not to...chances”。 [3]本句中的as many countries可看作“as many countries as 20...”的省略形式。 I arrived in Liberia with MSF almost three months ago. When I saw the tragic scenes⑥ on the news, I felt it was my duty as a doctor to go there and offer　my help. I knew I was putting my life at risk⑦， but I thought, “ If I don't do it, who will？” It is important to remember that Ebola doesn't respect national boundaries⑧. There are no borders for doctors, for patients or for anyone else [4]involved in combating⑨ this terrible disease. [4]此处是形容词短语在句中作后置定语，修饰anyone else。 My mission was to relieve⑩ Emma, a Canadian specialist in infectious⑪ diseases at the end of her posting⑫. [5] Emma spent an hour with me in the staff room⑬ talking me through⑭ the daily routine⑮.As she talked, I could [6]hear at least three different languages being spoken at the tables around us.Later, Emma introduced me to some of the others working for or alongside⑯ MSF：Wilton, a young local man, who helped carry the very sick⑰ into the treatment clinic⑱ and who disinfected⑲ clothing and surfaces; Maisy, a retired⑳ public health official from Darwin, Australia, whose local team of volunteers educated people oneq \o(○,\s\up8(21))preventing infection；Alfonso, a soft­spokeneq \o(○,\s\up8(22)) Argentinian doctor in his 50seq \o(○,\s\up8(23))， who had previouslyeq \o(○,\s\up8(24)) worked oneq \o(○,\s\up8(25)) Ebola outbreakseq \o(○,\s\up8(26)) in Sierra Leone and Guinea. The list went on. I found that I was the only Chinese doctor among people of all ages, colours and beliefseq \o(○,\s\up8(27))， from every continent except Antarctica. With each person I met, I felt a growing sense of prideeq \o(○,\s\up8(28)) as part of this extraordinary team, whose devotioneq \o(○,\s\up8(29)) to the causeeq \o(○,\s\up8(30)) shone from their eyes. [5]本句中的“spend some time (in) doing sth.”意为“花时间做某事”。 [6]此处为“hear＋宾语＋宾语补足语”结构，宾补由v.­ing的被动形式充当。 In the few weeks since then, I have come to knoweq \o(○,\s\up8(31)) these people very well. We have worked together, surrounded byeq \o(○,\s\up8(32)) blood, vomiteq \o(○,\s\up8(33)) and death. But, although the death rateeq \o(○,\s\up8(34)) is very high, we will never give up oneq \o(○,\s\up8(35)) a patient, and our efforts [7]do sometimes end in miracleseq \o(○,\s\up8(36)). [7]此处的do用于强调谓语动词，意为“确实，的确”。 Just after my arrival, a family of six were brought here in the back of a vaneq \o(○,\s\up8(37)). All of them were infected. The twin girls and their parents soon died. We knew there was little hope for the brothers, but we did everything [8]we could to save them.When we visited the wardeq \o(○,\s\up8(38)) the next morning, we were amazed [9]to see that against all oddseq \o(○,\s\up8(39))， both boys were still alive. Pascal and Daniel have since made a full recoveryeq \o(○,\s\up8(40)). This small but unexpected success compensatedeq \o(○,\s\up8(41)) for many other less fortunate cases. [8]此处的we could为省略了关系代词that和谓语动词do的限制性定语从句；“to save them”为不定式短语，在句中作目的状语。 [9]此处为不定式短语作原因状语；see后接that引导的宾语从句。 To be caught up ineq \o(○,\s\up8(42)) such a crisiseq \o(○,\s\up8(43)) creates powerful bonds between peopleeq \o(○,\s\up8(44))， [10]not only between carers and patients，but also between all those who have come from different parts of the world and joined together in a common cause. It is so inspiringeq \o(○,\s\up8(45)) to have colleagues like Wilton, Maisy and Alfonso, not to mentioneq \o(○,\s\up8(46)) all the others I have worked with. [10]此处为“not only...but also...”结构，对between people作进一步的说明；“who...cause”为关系代词who引导的限制性定语从句，修饰先行词those，who在从句中作主语。 Now my time is almost upeq \o(○,\s\up8(47)). In a few days, someone else will arrive to step into my shoeseq \o(○,\s\up8(48))， and the tirelesseq \o(○,\s\up8(49)) work that the MSF members do in more than 70 countries and regions around the world will go on. In a world still facing so many problems, [11]it is absolutely essentialeq \o(○,\s\up8(50)) for us all to collaborate eq \o(○,\s\up8(51)) to create a global community with a shared future of peace and prosperityeq \o(○,\s\up8(52)). [11]it作形式主语，真正的主语是动词不定式；不定式短语“to create...prosperity”作目的状语；介词短语“with...prosperity”作后置定语，修饰a global community。 词汇注解 ①case n．[熟词生义][C]病例，病案，病人，伤员 a severe case of COVID­19新冠感染重症病例 ②vital['vaItl] adj.极其重要的，必不可少的 ③take any chances 心存侥幸，冒险 ④comrade ['kɒmrId] n．同志；朋友 ⑤virtual ['vɜːtʃuəl] adj.模拟的，虚拟的；很接近的，实质上的 virtual glass 虚拟的杯子 ⑥scene n．[C]情景，场面，场景 tragic scenes悲惨场景 ⑦put one's life at risk置某人的生命于危险中 ⑧respect national boundaries不跨越国界线(在此为拟人用法) ⑨combat ['kɒmbæt] v．防止，抑制 n．[U]战斗，[C]格斗 combat crime/disease抑制犯罪/疾病 ⑩relieve [rI'liːv] v．[熟词生义] 接替；给(某人)换班 ⑪infectious[In'fekʃəs] adj.传染性的，感染的(尤指通过呼吸) ⑫posting ['pəʊstI] n．[C]派驻，派任；帖子，消息 ⑬the staff room 办公室，员工休息室 ⑭talk sb through sth向某人详细解释某事，使某人理解某事 ⑮routine [ruː'tiːn] n．[C，U]常规，惯例，例行 daily routine日常事务/生活 ⑯alongside prep.与……一起，与……同时 ⑰the very sick(重症病人)属于“the＋adj.”结构，该结构可表示一类人。 ⑱clinic ['klInIk] n．诊所；门诊部 the treatment clinic门诊治疗部 ⑲disinfect [ˌdIsIn'fekt] v．为……消毒，给……杀菌 ⑳retired [rI'taIəd] adj.已退休的，已退职的 eq \o(○,\s\up3(21))educate sb on doing sth在做某事方面教育某人 eq \o(○,\s\up3(22))soft­spoken adj.低声细气的 eq \o(○,\s\up3(23))in one's 50s(在某人50多岁的时候)属于“in one's＋几十的复数形式”结构，该结构表示“在某人几十多岁时”。 eq \o(○,\s\up3(24))previously ['priːvIəsli] adv.先前，之前 previous adj.先前的，以往的 eq \o(○,\s\up3(25))work on从事……，致力于…… eq \o(○,\s\up3(26))outbreak n．[C]爆发，突然发生 eq \o(○,\s\up3(27))belief [bI'liːf] n．[C]信仰 eq \o(○,\s\up3(28))a sense of pride自豪感 eq \o(○,\s\up3(29))devotion [dI'vəʊʃ(ə)n] n．[U]奉献，忠诚，专心，热心 devotion to...对……的奉献/投入/忠诚(to为介词) eq \o(○,\s\up3(30))cause n．[熟词生义][C]事业，理想，目标 eq \o(○,\s\up3(31))come to know渐渐了解/认识 eq \o(○,\s\up3(32))be surrounded by...被……环绕/包围 eq \o(○,\s\up3(33))vomit ['vɒmIt] n．[U]呕吐物 eq \o(○,\s\up3(34))death rate死亡率 eq \o(○,\s\up3(35))give up on...放弃…… eq \o(○,\s\up3(36))miracle ['mIrək(ə)l] n．意外的幸运事；奇迹 end in miracles以奇迹告终 eq \o(○,\s\up3(37))van [væn] n．小型货车 eq \o(○,\s\up3(38))ward [wɔːd] n．病房 eq \o(○,\s\up3(39))against all odds尽管凶多吉少，尽管困难重重 odds [ɒdz] n．[pl.]逆境，不利条件；可能性，几率 eq \o(○,\s\up3(40))make a full recovery完全康复 eq \o(○,\s\up3(41))compensate ['kɒmpenseIt] v．弥补，补偿 compensate for...弥补…… eq \o(○,\s\up3(42))be caught up in...被困在……中；被卷入…… eq \o(○,\s\up3(43))crisis ['kraIsIs] n．[C，U]危难时刻，危机，危急关头 eq \o(○,\s\up3(44))create bonds between people在人们之间建立纽带 eq \o(○,\s\up3(45))inspiring adj.令人鼓舞的，启发灵感的 eq \o(○,\s\up3(46))not to mention更不用说 eq \o(○,\s\up3(47))one's time is almost up某人的时间快结束了 eq \o(○,\s\up3(48))step into one's shoes接替某人(的职责或工作) eq \o(○,\s\up3(49))tireless ['taIələs] adj.不知疲倦的，不觉疲劳的 eq \o(○,\s\up3(50))essential [I'senʃl] adj.完全必要的，必不可少的，极其重要的 eq \o(○,\s\up3(51))collaborate [kə'læbəreIt] v．合作，协作 eq \o(○,\s\up3(52))prosperity [prɒ'sperəti] n．[U]繁荣 课文译文 与无国界医生 奋战一百天 2015年3月22日 今天是个值得庆祝的日子。距离上次报告的病例已经过去整整一个月了。但重要的是我们不能心存侥幸，因此我们这些来自将近20个国家的20名医护人员兼战友高举虚拟的酒杯，相互致意。 大约三个月前，我跟随无国界医生组织来到利比里亚。 看到新闻里的悲惨场景时，我深感作为一名医生，我有责任去提供帮助。我知道这是在拿自己的生命去冒险，可转念一想：“如果我不做，谁会做呢？”我们要明白埃博拉病毒的传播不分国界，医生、病人以及参与抗击这一可怕疾病的任何人需要共同面对。 我的任务是接替任期结束的加拿大传染病专家埃玛。她花了一个小时在办公室向我交代日常事务。她说话的时候，我听到周围几张桌子旁传来至少三种不同语言的说话声。后来，埃玛向我介绍了为无国界医生组织工作或与该组织并肩作战的人们：威尔顿，一个年轻的当地男子，他负责帮忙送重症病人到门诊治疗部，并为他们的衣服和身体表面消毒；梅斯，来自澳大利亚达尔文市的一位退休公共卫生官员，他带领当地的志愿者团队对人们进行预防感染的教育；阿方索，一位50多岁、说话温柔的阿根廷医生，他曾在塞拉利昂和几内亚应对过埃博拉病毒爆发。名单仍在继续。我这才发现，他们是来自除南极洲外不同年龄、肤色、信仰的世界各地的人们，而我是其中唯一一名中国医生。和遇到的每个人一起工作，作为这个非凡团队的一员，我感到非常自豪，他们眼中闪烁着对这项事业的热爱。 接下来的几个星期里，我开始深入了解这些同伴。我们并肩战斗，一起面对血液、呕吐物和死亡。但是，尽管死亡率很高，我们从不放弃一位病人，我们的努力有时的确会产生奇迹。 我刚来不久，一家六口人被一辆小货车送到了这里。他们已经全部感染。双胞胎女孩和她们的父母很快就去世了。我们对两兄弟也没有抱什么希望，但还是尽最大努力去救治他们。第二天早上，当我们去查看病房时，我们惊奇地发现，尽管困难重重，但两个男孩都还活着。现在，帕斯卡和丹尼尔已经完全康复。这个出乎意料的成功虽然微乎其微，但也弥补了许多其他的不幸。 患难与共的经历在人们之间建立了紧密的纽带，不仅是护理人员和病人之间，还有所有来自世界各地、为共同的事业团结一致的人之间。有威尔顿、梅西和阿方索这样的同事真令人鼓舞，更不用说再加上所有和我们一起共事的人了。 现在我的任期快到了。几天后，会有其他人来接替我。无国界医生组织的各位成员在世界70多个国家和地区的不懈努力会一直延续下去。在一个仍然面临许多问题的世界上，共同创造一个具有和平与繁荣的未来的全球共同体对我们大家都是很有必要的。 Ⅰ.重点单词 核心单词 1．　boundary n．分界线；边界 2．　statistic n.
