There they are. We can see two beautiful specimens, Homo sapiens, young people. You see, they are a little confused. It's not really surprising, of course. So what could happen at any moment now? The girl goes first. That's how would you be. She doesn't know what's happening to her. That's what it's like at puberty. A gland in her brain—the pituitary gland, produces hormones that make her grow. There's nothing you can do about that. Then she shoots at first, the hands and the feet. Take a look —she needs new shoes.

他们在那。我们看见两个美丽的人，现代智人，年轻的人。你看到他们有点困惑。当然，这没什么可奇怪的。那现在会发生什么呢？女孩先开始发育（你也会这样的）。她不知道自己怎么了。这种状态就是青春期。她大脑里的垂体腺产生激素使她开始发育。这是不受人控制的。首先她快速长高，手脚变大。看啊，她现在需要新鞋了。

From now on, things start moving fast. Her breasts are now starting to grow. Ten years of age. Just image, the girl is now ahead of the boy, isn't she? Look at that boy. He doesn't have a clue what's going on. There he goes. While the girl's already starting to get pubic hair, the boy's only now embarking on puberty.

从现在开始，她开始快速发育。她的胸部也开始发育了（大概10岁时）。看啊，女孩现在是不是走在男孩前面了？再看男孩。他还没搞清楚发生了什么。他开始发育了。当女孩长出阴毛的时候，男孩才开始进入青春期。

The girl races ahead—pubic hair and breasts sprouting. And she shoots up ahead. She's growing so fast that she can't keep up herself. She no longer has her body under control. That must hurt.

女孩继续向前，阴毛和乳房发育。她长得如此快，她都跟不上自己的变化了。她控制不了自己的身体（这真让人伤心）。

It's time the boy got himself some new shoes. He sees all kinds of things happening in his underpants. His testicles start to grow. At least, that's what happens first. After the testicles, the penis also gets larger. Sometimes he also has an erection just like that. It just happens. If we are lucky we can catch a glimpse of that. The girl is now in the middle of her growth spurt. After her arms and legs her torso starts to grow. And now it's the turn of her hips and buttocks. They all get broad. The bones grow and there's an increase in fatty tissue.

男孩该买新鞋了。他注意到自己内裤里发生的动静了。他的睾丸开始长大。最后，那就是首先发生的。睾丸发育后，阴茎也增大。有时候他会出现那样的勃起。要是我们幸运的话我们可以看到。女孩现在走到了生长冲刺的中间阶段，在上下肢发育后现在她的躯干开始发育了。现在轮到她的髋部和臀部发育了，髋部和臀部均增宽。骨髂发育，脂肪组织也开始增加。

The boy now starts to get some pubic hair at last. And some hair starts growing under his arms. And now he starts losing control. It's all going too quickly for his proper left right left after all. And something funny starts happening to his neck. He develops an Adam's apple. That's also responsible for lowering his voice.

男孩现在终于开始长出阴毛了。腋下也长出腋毛。现在男孩开始失控了。所有这些都发生得太快了，他都要晕了。而且他的颈部出现了个有趣的东西——喉结，使他的声音变得低沉。
