（单词翻译）

One of the least pleasant things about being human is the appearance at adolescence¹ of pimples².

对于人类而言，最恼人的莫过于青春期脸上长痘痘了。

Not only do they make their entrance just at the time when people are most self-conscious, but they come and go for the rest of your life.

在人们最有自我意识的时候会冒痘痘，而且脸上的痘痘可能会反复发作。

It would almost be better to have a hairy face.

也许满脸毛发可能会更好。

Ironically, the general covering of our bodies in hair---what we call "fur" on other animals---is at the root of our problem with acne.

讽刺的是，我们身上的体毛，就是我们所说的其他动物的"皮毛"--就是我们脸上长粉刺的“罪魁祸首“。

In the course of evolution human beings lost their entirely³ hairy faces and now have a lot of exposed skin there: even a bearded man with bushy eyebrows⁴ has much of his face bare.

在进化的过程中，人类完全褪去了毛绒绒的面孔，逐渐露出大部分的皮肤：甚至是浓眉大眼的长满胡须的男人，他的面部皮肤都是光滑的。

The structures in the facial skin that once gave rise to hair, however, have not disappeared entirely: many still contain tiny vestigial hairs which do not grow.

面部皮肤的结构一旦长出毛发，就不会完全消失：很多还包含着微小残留的长不出来的毛发。
