　　She is widely seen as proof that good looks can last forever．But，at nearly 500 years of age，time is catching up with the Mona Lisa．　1　

　　“The thin，wooden panel on which the Mona Lisa is painted in oil has changed shape since experts checked it two years ago，” the museum said．　2　

　3　“It is very interesting that when you're not looking at her，she seems to be smiling，and then you look at her and she stops，” said Professor Margaret Livingstone of Harvard University．“It's because direct vision（视觉）is excellent at picking up detail，but less suited to looking at shadows．Da Vinci painted the smile in shadows．”

　　However，the actual history of the Mona Lisa is just as mysterious as the smile．　4　

　　In 1911，the painting was stolen from the Louvre by a former employee，who took it out of the museum hidden under his coat．He said he planned to return it to Italy．The painting was sent back to France two years later．　5　

A．Nearly 6 million people go to see the Mona Lisa every year，many attracted by the mystery of her smile．

B．This picture is now so valuable that no one can tell its exact price．Therefore，many thieves tried to stead it in any way they could think of．

C．Visitors have noticed the changes but repairing the world's most famous painting is not easy．Experts are not sure about the materials the Italian artist used and their current chemical state．

D．Da Vinci himself loved it so much that he always carried it with him，until it was eventually sold to France's King Francis I in 1519．

E．The health of the famous picture，painted by Leonardo da Vinci in 1505，is getting worse by the year，according to the Louvre Museum（卢浮宫博物馆）where it is housed．

F．During World War Ⅱ，French hid the painting in small towns to keep it out of the hands of German forces．Like many old ladies，the Mona Lisa has some interesting stories to tell．
