I was sleeping soundly last night when I was awakened by someone’s groans（呻吟）.I listened , and heard it was from Sam，a student from Africa. I really wanted to go on sleeping, as I had insomnia（失眠）and had just fallen asleep, but I couldn’t because Sam groaned louder and louder，showing he was seriously ill.

At that time , Robbie，a student from China , also got up to help. We found some pills，got some water , and helped him sit up to take them, hoping this would make his pain go down a little and get over the difficult time. If only daytime would come soon, everything would become easier.

Things went contrary相反）to our wishes. Sam’s condition developed from bad to worse. We telephoned the emergency service , and in no time an ambulance stopped in front of our gate. We helped the medical（医疗）workers carry Sam to the vehicle，and then both Robbie and I got in and took Sam to the hospital.

We helped him go through many medical examinations. After all kinds of tests，we were told that the final diagnosis（诊断）was appendicitis（盲肠炎）. Luckily , Sam didn’t need an operation because we brought him to the hospital in time. He got timely treatment.

After Sam felt much better , we rushed back to prepare ourselves for the class. We were a little tired , but we had certainly done something good，something right.

　　当你去超级市场购物时，常会看到商品上印有黑白相间、粗细不同的条纹，下面还有一排数字，这就是条形码。由线条“栅栏”组成的条形码，包含了国别、厂商、产品名称、重量、规格、型号等丰富信息，它已成了商品的身份证，入场券和“绿卡”。在国际市场上，没有条形码的产品只能摆在地摊，或置于货架的最低层压价贱卖。

　　商品有条形码，那么人呢出人意外的回答居然是：人也有，而且独一无二。

　　1985年，《自然》杂志上发表了英国莱斯特大学遗传学家亚历克·杰弗里的论文《DNA遗传指纹》，为法医与刑侦技术树立了一块新的里程碑。这种新技术能以极微量的血液、精液、唾液或人体组织对人作出鉴别。它是把人的体液和组织结构中所特有的成分离析出来，用一种特殊的放射性探针加以照射。

　　这对，“指纹印记”就将显示在放大的照片上。这些“指纹印记’’是一系列黑白相间，疏密不同的竖线条，看上去极像自选商品上的条形码。杰弗里说：“没有哪两个人的线条是以完全相同的模式排列的，除非是同卵双胞胎。”

　　打从《自然》杂志发表了杰弗里的研究论文之后，他立即声誉鹊起，英国移民局也来向他求教。原来，有一名从加纳来的男孩在伦敦希思罗国际机场被拒绝入境，这名男孩宣称自己是在英国出生的，后来随父亲返回非洲，现在要到英国来和母亲团聚，移民局官员怀疑他不是当初出境的那个男孩。后来，杰弗里根据男孩和他母亲以及母亲的其他儿女的DNA特征，证明了他们是一家人。结果，移民局接受了这种生物学上无可辩驳的证据，批准这个男孩在英国居留。

　　前些日子，巴西验尸官在对一名淹死河中的尸体进行检验后确认。这具尸体就是人们长期追捕的纳粹余孽门格尔。这个家伙当年曾在奥斯威辛集中营里屠杀了数以万计的老弱妇孺，被称为”死亡天使”。战后，他乔装潜逃，不知去向。巴西方面宣布这一结果后，当时的西德有关方面曾对照验尸报告，检查了门格尔生前的医疗和牙科记录，但仍然无法百打之百地肯定。后来，英国科学家采取了最先进的DNA检测法，将取自尸首的DNA同门格尔儿子的DNA怍了对比检查，最后确认那名淹死者就是门格尔本人无疑。

　　英国牛津大学的黑格尔伯格等专家从遗骨中回收DNA，通过聚合酶连锁反应将线粒体DNA加以放大，进行分析，他们声称，目前已可从5500年以前(相当于我国传说中“三皇五帝”的时代)的遗骸中回收DNA。这种遗骨DNA鉴定法已经引起生物学家、遗传学家、进化论者、历史学家和种族学家等的普遍关注与极大兴趣。

　　美国的专家认为，我们人类的基因是一份真正的“日记”，是历史与家谱的实录，由此上溯，可以查阅到人类的起源、进化和人种差异等一系列答案。

　　为此，他们建议收集南非的布许曼人、巴布亚新几内亚的巴布亚人、日本的阿伊努人等土著的 DNA，因为“每个种族都是通向遥远古代的窗口”。有人已经预言，达尔文的进化论可能将因此作出重大修正。

　　用最现代化的技术收集、分析和保存一些土著人种的DNA，通过数学手段分析它们之间的微细差别，很有可能绘制出古老部族的迁徙图，完成全世界各主要人种的进化谱系，从而揭开中、外历史上的许许多多的“千古之谜”。人的条形码的这种功能，其价值将比商品条形码高出千百倍！
