蒙娜丽莎，为什么没有眉毛？

Leonardo painted a lady with no brows. 达芬奇画了一位没有眉毛的女士。 The Mona Lisa has no eyebrows. 这幅画，就是《蒙娜丽莎》。 Some people say it was the fashion then. 有人说，当年流行剃掉眉毛。 Others say the paint slowly wore off. 也有人说，是颜料慢慢掉了。 Today we cannot be sure which is true. 今天我们也说不准哪个对。 But her smile still looks like a secret. 可她那微笑，还是像藏着秘密。
