Back with our puppy, and shes joined a group of other potential guide dogs.再来看我们的小,她刚加入了一群导盲犬培养对象。And what do you know? Shes also right-pawed.果不其然,她也是右撇子。Theres still a year of training to complete, but for now she can have fun.它们还要接受一年的训练,但眼下还可以开心地玩耍。Weve trained dogs for thousands of years to work with us, harnessing their incredible physical abilities.几千年来,我们训练来协助我们,充分利用了它们难以置信的体能。And the husky is one of the best there is. Theyre superb athletes.哈士奇是其中的佼佼者,它们是出类拔萃的运动员。Able to run for over 100 miles a day in sub-zero temperatures. And they love it.能在零下的温度每天奔跑超过一百六十公里。它们也喜欢这样。They have a coat of fur two layers thick that insulates them from the cold.它们的皮毛是厚厚的两层,足以抵御寒冷。Even at -60, they wont get frostbite.即使是零下六十摄氏度它们也不会冻伤。And when they need to cool down, like all dogs, they pant.需要散热时,它们和所有一样喘气。By looking at these huskies with a thermal camera, we can see that their mouths and tongues are white withthe heat that theyre expelling from their body core.通过热成像仪观察这些哈士奇,可以看出它们的嘴和舌头是白色的,这是它们在驱散体内的热量。And it means that when your dog is panting after a run, shes not puffed out, shes just cooling down.这意味着如果你的在奔跑后喘气,她并不是气喘吁吁,只是在散热。Its a dogs main method of losing heat.这是散热的主要方法。As theyre covered in fur, the only place they can really sweat is through their paws.它们全身覆盖皮毛,唯一能出汗的地方就是它们的爪子。Dogs have been our working companions for as long as we can remember.长久以来,都是我们的好帮手。Weve used the Basset Hounds nose to sniff out prey; the Rottweilers strength for guarding our homes; the Afghans sight and speed to give chase; and the Huskys endurance in extreme environments.我们利用巴吉度猎犬的鼻子来寻找猎物;利用罗威纳犬的力量来保卫家园;利用阿富汗猎犬的视力和速度来追捕;并利用哈士奇在恶劣环境中的忍耐力。But from the very beginning, weve also chosen dogs that are cute and give us comfort.但从一开始我们也选择了可爱,能给我们慰藉的。And no matter what the size, dogs have worked their way into our hearts. Its a strong emotional bond.不管它们体型如何,都在我们心中留有一席之地。这是一种强烈的情感纽带。And one that our rapidly growing puppy is just beginning to discover.我们成长迅速的小才刚刚接触这一情感。201506/377745栏目简介:《造物小百科How its made》介绍了许多东西的制作或者说发明方法,非常实用。其中的英语视频发音地道,内容浅显易懂,过程形象生动,是提高英语听力水平,积累英语知识和一些简单生活常识的好素材。201508/391058You meet someone whose face is familiar, but you can’t remember their name.

The little scar in the middle of your abdomen marks the place where,for about nine glorious months,all the nutrients you needed to grow and develop and survive flowed straight into your bloodstream,while you just floated around in a sac of amniotic fluid.你腹中央的那道小伤疤就是,那九个光荣岁月里,你赖以生存成长的所有的营养素 直接流入你血液的地方 而你仅仅漂浮羊膜的液体中。But have you ever wondered what was going on with your other bodily functions,while you were in that enclosed space?To put it a little more bluntly.did you,you know,pee and poop in there? The answer to question #1 is yes,definitely:embryos start peeing after just two months of development.around the time they first begin swallowing-and,therefore,drinking-amniotic fluid.但你是否想过,当你处在这个封闭的空间内时,身体的其他部分发生了什么?更直白点说,你有没有在那里尿尿和便便?对第一个问题的是,当然:刚发育两个月的胚胎就已开始尿尿了,和他们第一次开始吞咽的时间大致相同,那么,他们必然会喝羊水。This does essentially mean that fetuses spend seven months drinking their own pee,but thats actually not as gross as it sounds.这的确意味着这些胚胎喝自己的尿足足喝了七个月,但这没有听上去那么恶心。For one thing,urine-unlike feces-is sterile,so it doesnt contain bacteria that could make the fetus sick.Also,the waste products we normally get rid of by urinating,like excess nitrogen,are instead filtered from the fetus and delivered,through the umbilical cord,back to the mother for disposal.And what about the waste we normally get rid of by pooping?首先,与便便不同的是 尿是无菌的,它并不含可导致胚胎生病的细菌。同时,我们通常靠尿排出体外的废物,比如多余的氮 被胚胎过滤 通过脐带,运送到母亲的体内 进而排出体外。那么 我们通常通过便便排泄的废物呢?Well,mom takes care of that,too-indirectly.She digests food before it gets to the baby.absorbing nutrients like sugar and protein into her bloodstream and then passing those nutrients to her fetus through the umbilical cord.So most of the potential poop products stay with the mother.The fetuss digestive system isnt totally empty,though:some waste does go there and get broken down by acidic bile in the small intestines,producing a slimy,sticky greenish mass called meconium.哦,母亲也一样照顾到了,不过是间接地。食物到达婴儿前,母亲先做初步消化,将糖类 蛋白质等营养物质吸收到自己血液内 之后通过脐带将这些营养物质传给婴儿。因此,大多数“致便物”仍留在母亲体内。而胚胎的消化系统中并非什么也没有:一些废物会到达那里 被小肠内的胆汁酸分解,产生黏糊样的,粘粘的物质,胎便。But,unlike the large intestine of everyone outside a womb.a fetuss large intestine is mostly sterile and devoid of the billions of bacteria that break down our waste,and make up as much as 50% of the brown pulp known as feces.So the green,sticky mass that forms in a fetuss small intestines eventually becomes a green,sticky,and mostly bacteria-free mass inside the babys first dirty diaper.但是,和每个脱离子宫的人的大肠不同的是,胚胎的大肠内几乎是无菌的。没有数十亿细菌来分解体内产生的废物 同时组成了50%的屎黄色的黏黏排泄物 便便。那么 在胚胎小肠内形成的绿色粘稠物,最终成为了绿油油的,粘粘的,几乎无菌的物质 并驻留在宝宝第一个尿布里。And in a way,its the first-and last-clean poop in anyones life.同时,这也是人生命中第一泼,也是最后一泼干净的便便。201503/363275
