7、tes that connected the Far East with South Asia, Africa, the Middle East and southern Europe. Of course, when humans travel they carry their pathogens with them. So scientists and historians have wondered if the Silk Road was a transmission route not just for goods, but for infectious disease.Now we

8、 have the first hard evidence of ancient Silk Road travelers spreading their infections. The find comes from a 2,000-year-old latrine that had first been excavated in 1992. The report is in the Journal of Archaeological Science.So the site is a relay station on the Silk Road in northwest China. Its

9、just to the eastern end of the Tarim Basin, which is a large arid area just to the east of the Taklamakan desert, and not far from the Gobi Desert. So this is a dry part of China.Piers Mitchell, paleopathologist at the University of Cambridge, and one of the studys authors, along with his student Iv

10、y Yeh and colleagues in China.In the latrine, archaeologists found used hygiene sticks wrapped with cloth. These were used for what you think they were used for.This excavation was great because the cloth was still preserved and the feces was still adherent to the cloth on some of the sticks. So the

11、 archaeologist kept these sticks in the museum. And so my Ph.D. student, Ivy Yeh, whos first author on the paper, she went out to China took some scrapings from the feces adherent to the cloth. So we were then able to analyze that down the microscope when she brought it back to Cambridge.Where they

12、found eggs from parasitesincluding one from a liver fluke.And thats the exciting one because thats only found in eastern and southern China and in Korea, where they have marshy areas that have the right snails and the right fish.The fluke needs snails and fish for its lifecycle, but there were no su

13、ch snails or fish in this dry region of China. So the unlucky traveler who harbored the parasite had to have transported the disease to that spot.Well firstly it tells us that people were doing very long journeys along the Silk Road and you might think thats obvious. But no one really knew how long

14、people were traveling. Some people may have been trading, only going short distances selling their goods on to the next person. And so the goods might have gone all the way along the Silk Road, but people might not. But we know that some people were doing huge distances.Secondly it shows that this w

15、as, would be a viable route for the spread of those other infectious diseases like Bubonic plague and leprosy and anthrax that people had previously suggested might have been spread between East Asia and Europe along the Silk Road. Because modern genetic analyses have shown similarities between the

16、strains of one end and the other.Mitchell says theres much more work to be done to better understand the spread of diseases around the world. Perhaps from analyzing skeletonsor various other kinds of remainsto be found along the Silk Road.Thanks for the minute for Scientific American 60-Second Scien

17、ce Science. Im Cynthia Graber.数千年来，海洋与陆地之间的贸易路线丝绸之路将远东、南亚、非洲、中东和南欧连接起来。当然，人类在旅行时也携带着病原体。科学家和历史学家怀疑，丝绸之路运输的不仅仅是货物，还有传染性疾病。现在，我们掌握了第一个有力的证据，证明古代丝绸之路的游客传播了自身的疾病。这项结果源自1992年发掘的一个有2000年历史的茅厕。该项研究结果发表在考古科学：报告杂志上。“这里是中国西北部丝绸之路上的一个中转站。位于塔里木盆地的东端，塔里木盆地这块广阔干旱的地区位于塔克拉玛干沙漠的东部，距离戈壁沙漠不远。这里是中国的一个干旱地带。”皮尔斯米切尔是剑桥大学的

18、古生物病理学家，同时也是该报告的作者之一，他和他的学生艾薇叶以及来自中国的同事们一同进行了该项研究。考古学家在发掘的茅厕里发现了用过的卫生棍，这些卫生棍用布裹着。这些东西的用途和你认为的一样。“这次发掘意义很大，因为这些布仍然保存完整，而且排泄物还附着在一些棍子裹着的布上。考古学家把这些卫生棍保存在博物馆。我的博士学生艾薇叶，同时也是该论文的第一作者，去中国刮取了布上的一些排泄物。这样，我们就能够在显微镜下分析她带回剑桥的样本。”他们发现了寄生虫的卵，还有肝吸虫的卵。“这项发现让我们兴奋不已，因为这些只存在于中国东部和南部以及韩国，那里的沼泽地有含有这些病原体的蜗牛和鱼类。”肝吸虫需要依靠蜗牛

19、和鱼类进行生命循环，但是中国干旱地区没有这些病原体所需要的蜗牛和鱼类。所以，携带着寄生虫的倒霉游客将疾病带到了该地区。“首先，这告诉我们，人们沿着丝绸之路长途跋涉，你可能认为这是显而易见的。但是没有人确切知道人们到底走了多远。有些人可能一直在进行贸易活动，他们只走了很短的距离，将自己的货物转卖给他人。所以，货物可能要一直沿着丝绸之路运输，但是人就不一定了。不过我们知道有些人的确走了很远的距离。”“其次，这项发现表明，这可能也是黑死病、麻风病和炭疽等传染疾病的传播路线，此前人们认为这些疾病沿着丝绸之路在东亚和欧洲之间传播。因为，现代基因分析表明，菌株一端和另一端存在相似性。”米切尔表示，为了更好

20、的了解疾病在世界范围内的传播，还有更多的工作要做。也许可以分析在丝绸之路上发现的骨骼或是其他类型的遗留物。重点讲解：1. come from 来自;始于;例句：The news comes from a reliable source.这消息来自可靠的*。2. along with 与一起;例句：She came to dinner along with her boyfriend.她和她的男朋友一道来用餐。3. be adherent to 黏附;附着;例句：The brass plate must be adherent to the steel.黄铜片必须和钢粘结。sell on 转卖;

21、倒卖;例句：Mr Farrier bought cars at auctions and sold them on.法里尔先生拍得汽车后再将其转手。2020托福听力练习：气味大师环尾狐猴Ring-tailed lemurs are a chatty lot.They vocalize to exchange information.And they also communicate via a veritable smorgasbord of stinky secretions they use to mark their territory and advertise their roman

22、tic availability.But male lemurs, which have more scent glands than do females, are really masters of muskbecause they sometimes mix their smelly secretions to produce a veritable bouquet of stank.And now researchers have a better idea why.Male lemurs sometimes use the scent glands on their wrists t

23、o mark tree branches and saplings.Other times, they double down, rubbing their wrists against glands on their chests to create a foul and funky fusion.This special blend can then be smeared over objects or wiped onto their tails, which the males wave at their rivals in a display that scientists refe

24、r to as a “stink fight.”But why create such a custom combination?Perhaps adding the oily exudate from the chest alters the information conveyed by the wrist.Or maybe it acts as a kind of preservative that makes the wrist signal longer lasting.To find out, researchers gathered secretions from a dozen

25、 ring-tailed lemurs at the Duke Lemur Center in North Carolina.They then presented male lemurs with wooden dowels that were doused with either the wrist fragrance, the chest scent, or a mixture of the two.And they found that males spent more time sniffing the stick with the mixture, which suggests t

26、hat the fragrant combination does contain more interesting information than the solo scents alone.But the lemurs were even more interested in the odiferous amalgamation when it was left out to evaporate for 12 hours, licking the sticks to better access the dried volatile compounds.That observation s

27、upports the theory that mixing secretions actually boosts their staying power.The results are in the journal Royal Society Open Science.So while a rose is a rose is a rose, the perfume of the ring-tailed lemur is a complex concoction, the subtle meaning of which lies in the nose of the beholder.环尾狐猴

28、真的很健谈。它们发声的目的是交流信息。而且它们也会通过名副其实散发恶臭分泌物的混合物进行交流，而它们一般将这些分泌物用作标记领地及向异性求爱。但气味腺比雌性狐猴多的雄性狐猴才是真正的气味大师它们有时候会将那些臭味分泌物混合然后弄出一些散发恶臭的混合气。环尾狐猴或是气味大师.jpg而现在研究人员们已经对环尾狐猴这样做的原因有了进一步的了解。雄狐猴有时候会用手腕的腺体气味分泌物在树枝及嫩枝上做标记。其余时间它们就一直躺着，摩擦自己手腕上的腺体分泌物到胸部并制造出一种散发强烈臭味的混合物。这种特殊混合物随后就被涂在一些物体或者附着在它们的尾巴上，而雄性狐猴向它们的情敌宣战摆动尾巴时就会起到交流作用，

29、而科学家们将此称为“臭气的较量”。但为什么要特别弄出这种臭味的混合物呢?研究人员分析了环尾狐猴的气味变化.jpg或许加入从胸部分泌出的油状物可以改变手腕部臭气所代表的信息。又或者它起到的是一种防腐剂的作用，让手腕的信号更持久。为了一探究竟，研究人员们从北卡莱罗纳州的杜克狐猴中心收集到了12只环尾狐猴的分泌物。然后他们分别将附着腕部气味，胸部气味及两者混合气味的木钉放到雄性狐猴面前。结果研究人员发现雄性狐猴会在混合气体前驻足，这表明相比单独气味，混合气体确实含有更多更有趣的信息。但在随后静置12小时待气体蒸发后，狐猴对混合气味更感兴趣，它们会舔这些木棍以便更好的接触到这种干燥挥发性的混合气体化合

30、物。这项观察实验证明了混合分泌物确实会促进狐猴驻足停留的理论。这项研究已在皇家社会公开科学杂志上发表。因此虽然一支玫瑰就是一支玫瑰而且只会散发出玫瑰的气味时，但环尾狐猴的香水可是极为复杂的混合物，而其中所蕴含的微妙含义只能交由当事者的鼻子品评。1.wipe onto 擦上例句:Wipe the lotion onto your face.你在脸上搽些护肤液。2.wave at 朝挥手(致意)例句:So why you just wave at her?为什么你只是对她招招手?3.find out 发现;使发作例句:I need to find out who tried to frame me.我得找出是谁企图诬陷我。4.stick with 坚持例句:If youre in a job that keeps you busy, stick with it.如果你所做的工作能让你很忙，那要坚持下去。托福听力中的50个美式习惯用语汇总一览
