chapter 1: The Power of Noses Hi there! My name is Dr. Ick. As my name suggests, I like all things icky, stinky, and gross! This is my good friend, Sam. He doesn't love stinky things as much as I do, but as a dog, he knows a lot about them. We're here to show you some of the smelliest things in the world!

第一章：鼻子的超能力 嗨，大家好！ 我叫伊克博士。 就像我的名字一样，我喜欢所有黏糊糊、臭烘烘、恶心吧唧的东西！ 这是我的好朋友萨姆。 他不像我这么喜欢臭东西，不过作为一只狗狗，他对臭味可了解得很呢。 今天我们就要带大家认识一些世界上最臭的东西！

Did you know that humans can smell some things as well as dogs can? No way! Yes way! Humans can be sensitive to certain scents. Some of these specific smells are bananas, flowers, blood, and even urine!

你知道吗，人类有些东西的嗅觉和狗狗一样灵敏哦？ 不可能！ 当然是真的！ 人类对某些气味会特别敏感。 这些特殊的气味包括香蕉、鲜花、血液，甚至还有尿液哦！

Some people are so sensitive to smells, they're called "super smellers"! Some super smellers are born with this ability, but other people can train their noses to become better smellers and use it for work!

有些人对气味特别敏感，大家都叫他们“超级嗅觉者”！ 有些超级嗅觉者天生就有这种能力，不过还有些人可以训练自己的鼻子，让嗅觉变得更灵敏，还能靠这个本领工作呢！

OLFACTORY BULB 300 MILLION Olfactory Receptors 220 MILLION Olfactory Receptors Dogs are still better smellers, though, right? That's right, Sam. Dogs have more olfactory receptor (say: ohl-FAK-tuh-ree rih-SEP-ter) cells in their noses than humans do. That means that dogs" special noses help them pick up more smells, and dogs recognize the scents much more quickly!

嗅球 3亿个嗅觉受体 2.2亿个嗅觉受体 不过狗狗的嗅觉还是更厉害，对不对？ 没错哦，萨姆。 狗狗鼻子里的嗅觉受体（读音：oh-FAK-tuh-ree rih-SEP-ter）细胞比人类多得多。 也就是说狗狗的特殊鼻子能帮它们闻到更多气味，而且识别气味的速度也快得多！
