Our Amazing Skin
我们神奇的皮肤 I-04 / 004

Our skin is like a bag that we live in. Inside the bag our bodies are mostly water. Our water is like the water in the sea. It is very salty. Also, like the ocean, we can lose our water. The wind and the sun could take it away. Our bag of skin keeps our body's ocean from drying up.

Our skin keeps out sunshine. Too much sun can hurt us. Skin also keeps out dirt. That's important because some kinds of dirt can make us sick. Our skin feels things. It feels warm things, cold things, things it touches, and things that hurt it. A campfire feels warm. A snowball thrown in our face feels cold and hurts us. A hug is the touch of another person's skin on our own.

Our hair is a special kind of covering. It helps keep things out of our eyes, ears, and nose. Hair is also good for keeping us warm. When we get goose bumps, our body hairs stand up. Then the hairs hold air close to our skin like a thick blanket. Hair keeps animals warm, too. Some animals have more hair than others, so they have a better blanket for cold weather.

Our nails are another special skin which are very hard. They help keep our fingers and toes from getting hurt. Our nails aren't as strong or sharp as the nails that animals have. But they are good for scratching backs and picking up coins.

译文

我们神奇的皮肤

我们的皮肤就像一个袋子一样把我们包裹在里面。在袋子里，我们的身体里大部分都是水分。像海水一样，我们身体里的水分也很咸；而且就像海洋一样，我们也会失去水分。风和阳光都会带走水分。而我们像袋子一样的皮肤能阻止身体里的水分枯竭。

我们的皮肤可以隔离阳光。太强的阳光会灼伤我们。同样地，皮肤也可以让我们与污物隔离。因为有些污物会让我们生病，所以这一功能非常重要。皮肤也可以感受外界事物，它能感知冷暖，以及感觉任何接触得到或会对它造成伤害的东西。篝火让我们觉得温暖，而砸在脸上的雪球则会让我们觉得冰冷和疼痛。拥抱则是我们的皮肤与他人的皮肤互相接触。

我们的毛发是一种特殊覆盖物。它能够防止东西飞进我们的眼睛、耳朵和鼻子。毛发同样也有保暖的功效。当我们起鸡皮疙瘩时，毛发就会竖起，然后毛发锁住空气使其紧贴着皮肤，就像一层厚厚的毛毯。对动物来说，毛发同样具有保暖的功效。有些动物的毛发比其他动物更浓密，所以它们有更好的“毛毯”来抵御寒冷。

我们的指甲是另一种特别的、坚硬的皮肤，它能保护我们的手指和脚趾免受伤害。虽然人类的指甲没有动物的指甲强壮、锋利，但是它们足以搔背，并且还能捡起硬币。
