课文讲解
Q: Let’s say you have a dog and a cat. If you run out of cat food, can you feed it dog food? 假设你有一只狗和一只猫。如果你的猫饲料用完了，可以用狗饲料喂猫吗？
(A) Of course I can. It’s healthy. 当然可以！很健康啊
(B) No way! It’s a bad idea. 绝对不行！这不是个好主意
(C) Only if the cat wants it. 只有在猫自己想要吃狗饲料的时候
A: Hopefully you guessed B because dog food is harmful to cats. Cat food contains proper proteins and necessary nutrients for felines. One of these must-have things is taurine. If a cat doesn’t receive taurine, it most certainly will die prematurely and will likely go blind or develop an enlarged heart. So, cat owners, please put your cat first and buy the proper food.
希望你猜的是B，因为狗饲料对猫有害。猫饲料含有适当的蛋白质和猫科动物所需的营养，其中一定要有的就是牛磺酸。如果没有吸收牛磺酸，猫会早夭，并可能失明或心肌肥大。所以，猫饲主们，请将您的猫放在第一顺位，去买合适的饲料吧。
Q: Snakes are able to eat animals much larger than themselves. Do you know how they do it? 蛇能够吃下比自己还大许多的动物。你知道牠们是怎么办到的吗？
(A) Snakes take small bites. 蛇小口咬食
(B) Snakes compact the food first. 蛇先将食物压紧
(C) Snakes change their jaws. 蛇会变动下巴
A: You may have escaped the clutches of a snake if you guessed answer C. Snakes have a unique jaw that widens to allow large animals like pigs and dogs to be consumed. Snakes’ complex jaws are highly mobile and able of bowing outward to increase the gape of their mouth. To ensure that the snake doesn’t lose tasty meals, a bone called the maxilla rotates and aids in pulling the meal into the snake’s mouth. Yummy!
如果你猜的是C，你可能已逃过蛇的捕捉。蛇有独特可变宽的下巴以吃下猪和狗等大型动物。蛇构造复杂的下巴容易活动，并能向外弯曲来增加张嘴的幅度。为了确保不会失去美味的食物，一种称为上颚骨的骨头会转动以帮助将食物拉进蛇的嘴巴里。好吃！

Q: When bones or skeletons are found, they are taken to a forensic laboratory for examination. Do you know how the forensic scientists tell if the bones belong to a make or a female? 当骨头或骨骼被发现时，会被带到法医实验室调查。你知道法医如何分辨骨头是属于男性还是女性吗？
(A) They use the skull and hip bones to tell if it is a man or woman. 他们用头颅和髋骨来分辨是男人或女人
(B) Police dogs are used to sniff out the gender. 警犬是用来嗅出性别的
(C) They test the blood in the bones to figure it out. 他们检验骨头里的血液而得知
A: If your guess is A, then maybe you have a future in criminal studies. The forensic scientists can look at skeletal remains and easily determine the gender because male and female bones are different. In the skull alone, there are three points of contrast: ridges over the eyes, a bone below the ear, and another bone in the back. What’s more, experts can look at hip bones too; women have wider, oval-shaped hips, built for pregnancy and childbirth.
如果你猜的是A，那你有研究犯罪的潜力。法医能看着残余骨骸就轻易地确定性别，那是因为男性和女性的骨头有所不同。单看头颅，就有三处差异：眼睛周围的突起处、耳朵下方的一块骨头，以及颅后的一块骨头。再者，专家也可看髋骨判断；女人有较宽、椭圆形的骨盆，是为了怀孕而形塑的。
Q: You often hear how effective stomach acid is when aiding in digestion. But why doesn’t stomach acid dissolve the stomach itself? 你常听说胃酸帮助消化多么有效，但是为什么胃酸不会将胃本身溶解呢？
(A) Aware of the damage it could cause, our bodies tell the acid not to do this. 我们的身体察觉可能产生的损害，因此叫胃酸别这么做
(B) A unique liquid coats the stomach to protect it from acid. 一种特殊的液体包覆胃来防止胃酸侵袭
(C) Gas inside the stomach keeps the power of the acid at bay. 装满气体的胃会快速运转来不使胃酸逼近
A: This question likely didn’t give you a stomachache if you guessed B. Our bodies create mucus that coats the inside of the stomach. The stomach lining is thus protected from acid. But this substance can be damaged if people are too stressed or drink too much alcohol. When this happens, it often causes an ulcer.
如果你猜B，这个问题应该没让你感到头痛。我们的身体产生包覆胃内部的黏液，胃壁便会免胃酸伤害。但若是人们压力过大或喝太多酒，这层物质就会被破坏。当此状况发生时，常会引发胃溃疡。
